The rapid assessment of fatigue severity in cancer patients: use of the Brief Fatigue Inventory.

Abstract: BACKGROUND Fatigue is a major disease and treatment burden for cancer patients. Several scales have been created to measure fatigue, but many are long and difficult for very ill patients to complete, or they are not easy to translate for non-English speaking patients. The Brief Fatigue Inventory was developed for the rapid assessment of fatigue severity for use in both clinical screening and clinical trials. METHODS The study enrolled 305 consecutive, consenting adult inpatients and outpatients with cancer who could understand and complete the self-report measures used in the study. The same instruments also were administered to 290 community-dwelling adults to obtain a comparison sample. Research staff completed a form that indicated the primary site and stage of the cancer, rated the Eastern Cooperative Oncology Group performance status of the patient, described the characteristics of the pain, and described the current pain treatment being provided to the patients. RESULTS The BFI was shown to be an internally stable (reliable) measure that tapped a single dimension, best interpreted as severity of fatigue. It correlated highly with similar fatigue measures. Greater than 98% of patients were able to complete it. A range of scores defining severe fatigue was identified. CONCLUSIONS The BFI is a reliable instrument that allows for the rapid assessment of fatigue level in cancer patients and identifies those patients with severe fatigue.

The International Neuroblastoma Pathology Classification (the Shimada system)

Abstract: BACKGROUND The International Neuroblastoma Pathology Committee, which is comprised of six member pathologists, was convened with the objective of proposing a prognostically significant and biologically relevant classification based on morphologic features of neuroblastic tumors (NTs) (i.e., neuroblastoma, ganglioneuroblastoma, and ganglioneuroma). METHODS A total of 227 cases were reviewed. Consensus diagnoses from morphologic features (criteria described separately) based on five of six or six of six agreements by the reviewer pathologists were used for prognostic analysis. Prognostic effects of morphology, both individual and in combination, taken in conjunction with age (Shimada classification, histologic grade, and risk group), were analyzed. RESULTS Approximately 99% of cases (224 of 227) had consensus diagnoses for categorization: neuroblastoma (Schwannian stroma-poor), 190 cases; ganglioneuroblastoma, intermixed (Schwannian stroma-rich), 5 cases; ganglioneuroma (Schwannian stroma-dominant) maturing, 1 case; ganglioneuroblastoma, nodular (composite Schwannian stroma-rich/stroma-dominant and stroma-poor), 19 cases; and NT-unclassifiable, 9 cases. For the NTs, subtype (93% consensus: undifferentiated, 6 cases; poorly differentiated, 155 cases; and differentiated, 15 cases), mitosis-karyorrhexis index (90% consensus: low, 94 cases; intermediate, 40 cases; and high, 37 cases), mitotic rate (75% consensus: low, 89 cases; high, 50 cases; and not determined, 4 cases), and calcification (100% consensus: yes, 110 cases and no, 80 cases) were recorded. Statistical analysis demonstrated that the Shimada classification system (90% consensus; 3-year event free survival: 85% for the group with favorable histology and 41% for the group with unfavorable histology; P = 0.31 × 10−9) had a significantly stronger prognostic effect than individual features and other combinations. CONCLUSIONS The International Neuroblastoma Pathology Classification, a system based on a framework of the Shimada classification with minor modifications, is proposed for international use in assessing NTs.

Langerhans cell histiocytosis: diagnosis, natural history, management, and outcome.

Abstract: A panel of experts representing the Histiocyte Society has suggested that the original terminology for the various syndromes in the “histiocytosis X” category (eosinophilic granuloma, Letterer-Siwe disease, and Hand-Christian-Schuller syndrome) be discarded and replaced by the term Langerhans cell histiocytosis (LCH) (Chu et al. 1987). This is because the proliferative cell which causes these entities is known to be the Langerhans cell.

Cognitive deficits after postoperative adjuvant chemotherapy for breast carcinoma.

Abstract: BACKGROUND A number of patients who have undergone adjuvant (CMF) chemotherapy for operative primary breast carcinoma have reported impaired cognitive function, sometimes even years after completion of therapy. The possible role of cytostatic treatment as a causative factor has scarcely been investigated. The objective of the current study was to examine the late effects on neuropsychologic functioning of CMF adjuvant chemotherapy given to patients with breast carcinoma. METHODS Thirty-nine breast carcinoma patients who had been treated with adjuvant CMF (6 courses) followed (n = 20) by 3 years of tamoxifen 20 mg daily or not (n = 19) were examined with neuropsychologic tests and interviews. The control group consisted of 34 age-matched axillary lymph node negative breast carcinoma patients who received the same surgical and radiation therapy but no systemic adjuvant treatment. The CMF patients were examined a median of 1.9 years after the sixth CMF course, and the controls a median of 2.4 years after surgery of the primary tumor. RESULTS Patients treated with CMF reported significantly more problems with concentration (31% vs. 6%, P = 0.007) and with memory (21% vs. 3%, P = 0.022) than the control patients. No relation was found between reported complaints and results on the neuropsychologic tests. Impairment in cognitive function was found in 28% of the patients treated with chemotherapy compared with 12% of the patients in the control group (odds ratio 6.4 [95% confidence interval 1.5–27.6] P = 0.013). Hormonal therapy had no influence on patients' self-reports of symptoms or cognitive function. Cognitive impairment following chemotherapy was noticed in a broad domain of functioning, including attention, mental flexibility, speed of information processing, visual memory, and motor function. CONCLUSIONS Breast carcinoma patients treated with adjuvant CMF chemotherapy have a significantly higher risk of late cognitive impairment than breast carcinoma patients not treated with chemotherapy (OR 6.4). This cognitive impairment is unaffected by anxiety, depression, fatigue, and time since treatment, and not related to the self-reported complaints of cognitive dysfunction.

Terminology and morphologic criteria of neuroblastic tumors : recommendations by the International Neuroblastoma Pathology Committee

Abstract: BACKGROUND As part of the international cooperative effort to develop a complete set of International Neuroblastoma Risk Groups, the International Neuroblastoma Pathology Committee (INPC) initiated activities in 1994 to devise a morphologic classification of neuroblastic tumors (NTs; neuroblastoma, ganglioneuroblastoma, and ganglioneuroma). METHODS Six member pathologists (H.S., I.M.A., L.P.D., J.H., V.V.J., and B.R.) discussed and defined morphologically based classifications (Shimada classification; risk group and modified risk group proposed by Joshi et al.) on the basis of a review of 227 cases, using various pathologic characteristics of the NTs. The classification-grading system was evaluated for prognostic significance and biologic relevance. RESULTS The INPC has adopted a prognostic system modeled on one proposed by Shimada et al. It is an age-linked classification dependent on the differentiation grade of the neuroblasts, their cellular turnover index, and the presence or absence of Schwannian stromal development. Based on morphologic criteria defined in this article, NTs were classified into four categories and their subtypes: 1) neuroblastoma (Schwannian stroma-poor), undifferentiated, poorly differentiated, and differentiating; 2) ganglioneuroblastoma, intermixed (Schwannian stroma-rich); 3) ganglioneuroma (Schwannian stroma-dominant), maturing and mature; and 4) ganglioneuroblastoma, nodular (composite Schwannian stroma-rich/stroma-dominant and stroma-poor). Specific features, such as the mitosis-karyorrhexis index, the mitotic rate, and calcification, were also included to allow the prognostic significance of the classification to be tested. Recommendations are made regarding the surgical materials to use for an optimal pathobiologic assessment and the practical handling of samples. CONCLUSIONS The current article covers the essentials and important points regarding the histopathologic evaluation of NTs. Using the morphologic criteria described herein, the INPC is proposing the International Neuroblastoma Pathology Classification.

Having children after cancer. A pilot survey of survivors' attitudes and experiences.

Abstract: BACKGROUND Although the prevalence of infertility after cancer treatment and the health of the offspring of survivors have been studied, little information has been available about survivors' attitudes, emotions, and choices with regard to having children. METHODS A questionnaire was received by 283 patients from the Cleveland Clinic Foundation tumor registry who were diagnosed before age 35 years, were age 18 years or older at the time of the survey, and were free of disease. The SF-36, a measure of health-related quality of life, was included, as well as questions about demographic and medical background, reproductive and fertility history, and a variety of concerns about having children after cancer. RESULTS The response rate to the survey was 47%, yielding a sample of 43 men and 89 women who had had cancer at various sites. Their mean age at diagnosis was 26 years and the mean time since diagnosis was 5 years. Before cancer, 35% had at least 1 child, compared with 46% currently. Of those currently childless, 76% want children in the future. Although about half of the entire sample view themselves as having impaired fertility, only 6% have undergone infertility treatment. Nineteen percent have significant anxiety that their cancer treatment could impact negatively on their children's future health. Of women, 18% fear that a pregnancy could trigger a cancer recurrence. Only 57% received information from their health care providers about infertility after cancer. Other reproductive concerns were discussed less often. Only 24% of childless men banked sperm before treatment. SF-36 scores were very similar to normative data for healthy Americans of similar age. About 80% of the sample viewed themselves positively as actual or potential parents. Feeling healthy enough to be a good parent after cancer was the strongest predictor (P < 0.001) of emotional well-being as measured by the Mental Component Score of the SF-36. CONCLUSIONS The great majority of younger cancer survivors see their cancer experience as potentially making them better parents. Those who are childless want to have children in the future. Many, however, are left with significant anxieties and insufficient information about reproductive issues. Cancer 1999;86:697–709. © 1999 American Cancer Society.

International Union Against Cancer. Classification of isolated tumor cells and micrometastasis.

Abstract: Background Findings of isolated (disseminated or circulating) tumor cells (ITC) by immunocytochemistry and molecular pathology methods have led to varied interpretations and different applications of the TNM system. Methods An analysis of the relevant literature was undertaken. In addition, optional proposals for the classification of ITC, micrometastasis, and cytologic results in pleural and peritoneal washings are presented. Results Immunocytochemistry has a lower false-positive rate than nonmorphologic methods such as flow cytometry or the polymerase chain reaction; therefore the method(s) used always should be recorded. At the current time, the independent prognostic significance of ITC in regional lymph nodes and in the general circulation (blood, bone marrow, and other distant sites) is difficult to assess. To enable comparisons of treatment results and to avoid variation in staging, a finding of ITC should not be considered in the TNM and residual tumor (R) classifications, at least not at the current time. However, for future evaluation of their prognostic significance, the respective findings should be documented according to uniform criteria. Conclusions ITC should be distinguished from micrometastasis. To investigate the independent prognostic significance of ITC and of positive lavage cytology, uniform data collection according to the proposed coding schema is recommended.

Effects of physical activity on the fatigue and psychologic status of cancer patients during chemotherapy.

Abstract: BACKGROUND Fatigue is a common and often severe problem in cancer patients undergoing chemotherapy. The authors postulated that physical activity training can reduce the intensity of fatigue in this group of patients. METHODS A group of cancer patients receiving high dose chemotherapy followed by autologous peripheral blood stem cell transplantation (training group; n = 27) followed an exercise program during hospitalization. The program was comprised of biking on an ergometer in the supine position following an interval training pattern for 30 minutes daily. Patients in the control group (n = 32) did not train. Psychologic distress was assessed at hospital admission and discharge with the Profile of Mood States and Symptom Check List 90. RESULTS By the time of hospital discharge, fatigue and somatic complaints had increased significantly in the control group (P for both < 0.01) but not in the training group. Furthermore, by the time of hospital discharge, the training group had a significant improvement in several scores of psychologic distress (obsessive-compulsive traits, fear, interpersonal sensitivity, and phobic anxiety) (P value for all scores < 0.05); this outcome was not observed in the control group. CONCLUSIONS The current study found that aerobic exercise can reduce fatigue and improve psychologic distress in cancer patients undergoing chemotherapy.

Extramedullary plasmacytoma: tumor occurrence and therapeutic concepts.

Abstract: Background Extramedullary plasmacytoma (EMP) is a rare entity belonging to the category of non-Hodgkin lymphoma. EMPs make up 4% of all plasma cell tumors and occur mainly in the upper aerodigestive tract (UAD). Seven patients with EMP included in this evaluation were under the authors' care and have been clinically followed since 1990. Because there are no general guidelines for the treatment of patients with EMP, the authors tried to obtain detailed data about the occurrence of this disease and also reviewed the therapies that have been used. To do so, they evaluated all EMP cases published in the medical literature until now and included their own experience. Methods Based on the clinical course and follow-up of their own EMP patients, the authors evaluated and reinvestigated all EMP cases cited in MEDLINE, Index Medicus, DIMDI (Deutsches Institut fur medizinische Dokumentation und Information, Cologne, Germany), and the reference lists of the publications found through these sources. Results In a detailed literature search, more than 400 publications between 1905 and 1997 were found, and these revealed that EMP mainly occurs between the fourth and seventh decades of life. Seven hundred fourteen cases (82.2%) were found in the UAD, and 155 cases (17.8%) were found in other body regions. The following therapeutic strategies were used to treat patients with EMP of the UAD: radiation therapy alone in 44.3%, combined therapy (surgery and radiation) in 26.9%, and surgery alone in 21.9%. The median overall survival or recurrence free survival was longer than 300 months for patients who underwent combined intervention (surgery and radiation). This result was statistically highly significant (P = 0.0027, log rank test) compared with the results for patients who underwent surgical intervention alone (median survival time, 156 months) or radiation therapy alone (median survival time, 144 months). In most cases of non-UAD EMP, surgery was performed (surgery alone, 55.6%; surgery and radiation combined, 19.8%; radiation alone, 11.1%), but there were no statistical differences in survival (P = 0.62). Overall, after treatment for EMP in the UAD, 61.1% of all patients had no recurrence or conversion to systemic involvement (i.e., multiple myeloma, MM); however, 22.0% had recurrence of EMP, and 16.1% had conversion to MM. After treatment for EMP in non-UAD areas, 64.7% of all patients had no recurrence or MM, 21.2% had recurrence, and 14.1% had conversion to MM. Conclusions The current investigation provides evidence that surgery alone gives the best results in cases of EMP of the UAD when resectability is good. However, if complete surgical tumor resection is doubtful or impossible and/or if lymph node areas are affected, then combined therapy (surgery and radiation) is recommended. These results, which were obtained from retrospective studies, should be confirmed in randomized trials comparing surgery with combined radiation therapy and surgery.

Pathologic findings from the National Surgical Adjuvant Breast Project (NSABP) eight-year update of Protocol B-17: intraductal carcinoma.

Abstract: BACKGROUND This report is an 8-year update of the authors' previous findings from National Surgical Adjuvant Breast Project (NSABP) Protocol B-17, which relates to the influence of pathologic characteristics on the natural history and treatment of intraductal carcinoma (DCIS). METHODS Nine pathologic features observed in a pathologic subset of 623 of 814 evaluable women enrolled in this randomized clinical trial were assessed for their role in the prediction of second ipsilateral breast tumors (IBT), other events, and selection of breast irradiation (XRT) following lumpectomy. RESULTS The frequency of subsequent IBT was reduced from 31% to 13% (P = 0.0001) by XRT. The average annual hazard rates for IBT were reduced by XRT for all pathologic features examined. Four characteristics were individually noted to be significantly related to IBT, but only moderate-to-marked and absent-to-slight comedo necrosis were found to be independent high and low risk predictors, respectively, for such an event in patients of both treatment groups. XRT effected a 7% absolute reduction at 8 years in the low risk group. Despite a relatively high incidence (≈40%) of IBT consisting of invasive cancer, mortality due to breast carcinoma after DCIS for the entire cohort was found to be only 1.6% at 8 years. CONCLUSIONS The degree of comedo necrosis in patients with DCIS appears to be sufficient for discriminating between high and low risks for IBT following lumpectomy for DCIS. Although margin status, unlike in our previous report, was found to have only a slight or borderline influence on the frequency of IBT at 8 years, excision of DCIS with free margins is advised. The low risk group exhibits a statistically significant reduction of IBT from XRT. The decision to forgo XRT in the treatment of this singular subset of patients would appear to depend on clinical considerations and the input of informed patients rather than being standard practice.

"Malignancy" in meningiomas: a clinicopathologic study of 116 patients, with grading implications.

Abstract: BACKGROUND Due to the rarity of malignancy in meningiomas, prior studies have been limited to small series. Controversies regarding the definition of malignant meningioma have complicated matters further. Although histologic anaplasia and extracranial metastasis are established criteria, the former is difficult to define and the latter represents a clinical finding. Traditionally, brain invasion has also been accepted, although this has recently been debated. In a prior series, the authors were unable to prove that 23 meningiomas that had invaded the brain were more aggressive than atypical meningiomas. METHODS The authors expanded their analysis to include 116 patients diagnosed with “malignant meningioma” due to brain invasion, frank anaplasia (20 mitoses per 10 high-power fields or histology resembling carcinoma, sarcoma, or melanoma), and/or extracranial metastasis. Patients were followed until death or for a median of 3.7 years. RESULTS Survival time was highly variable, ranging from 10 days to 24 years. In multivariate analysis, histologic anaplasia (P = 0.0035), subtotal resection (P = 0.0038), 20 mitoses per 10 high-power fields (P = 0.0071), and nuclear atypia (P = 0.0068) were associated with poor survival. Of the 89 cases of meningioma that had invaded the brain, 23% were otherwise benign, 61% were otherwise atypical, and 17% were frankly anaplastic. Those without anaplasia behaved similarly to atypical meningiomas from the authors' prior study. In contrast, anaplastic meningiomas were usually fatal, associated with a median survival of 1.5 years. CONCLUSIONS Based on these findings, the authors suggest that brain invasion constitutes an additional criterion for the diagnosis of atypical meningioma (World Health Organization [WHO] Grade II), whereas frank anaplasia indicates high grade (WHO Grade III–IV) malignancy.

The prognostic significance of amplification and overexpression of c-met and c-erb B-2 in human gastric carcinomas.

Abstract: BACKGROUND The c-met and the c-erb B-2 protooncogenes belong to a family of tyrosine kinase growth factor receptors. Abnormalities of these oncogenes and protein products have been reported in several cancers. The authors investigated the correlation between clinical factors and amplification or overexpression of the c-met and/or c-erb B-2 gene in Japanese patients with gastric carcinoma patients, with a focus on prognostic significance. METHODS Amplification and overexpression of c-met and c-erb B-2 were investigated retrospectively in 128 gastric carcinoma patients by using immunohistochemistry and Southern blot hybridization. Survival analysis was performed with the Kaplan–Meier test, and the log rank test was used for statistical analysis. RESULTS Overexpression of c-met and c-erb B-2 was observed in 46.1% and 16.4% of gastric carcinoma cases, respectively. Gene amplification of c-met and c-erb B-2 was detected in 10.2% and 11.7% of gastric carcinoma cases, respectively. Amplification and overexpression of c-met were correlated significantly with depth of tumor invasion and lymph node metastasis, whereas amplification and overexpression of c-erb B-2 were correlated significantly with histologic type. The survival rate of patients with amplification and/or overexpression of c-met or c-erb B-2 was significantly poorer than that of patients with no amplification or overexpression. Multivariate analysis revealed that c-met overexpression and lymph node metastasis were independent prognostic factors. CONCLUSIONS These data suggest that overexpression and/or gene amplification of c-met and c-erb B-2 may be prognostic factors in gastric carcinoma.

Epithelioid hemangioendothelioma of the liver: a clinicopathologic study of 137 cases.

Abstract: BACKGROUND Epithelioid hemangioendothelioma (EHE) is a rare neoplasm of vascular origin that occurs in the liver and other organs; its etiology is unknown. METHODS The authors analyzed the clinicopathologic and immunohistochemical features of 137 patients with EHE of the liver in an attempt to identify features that might predict tumor behavior. To their knowledge, this article represents the largest series reported from one institution. RESULTS Patients were ages 12–86 years; 84 (61%) were females and 53 (39%) were males. They presented with nonspecific symptoms such as right upper quadrant pain or weight loss. Macroscopically, the tumors usually were multiple. They typically were white, firm to hard, and ranged in size from 0.2–14 cm. Histologically, the tumors were comprised of dendritic and epithelioid cells that often contained vacuoles representing intracellular lumina. The stroma was fibrous, with myxohyaline areas. Immunohistochemically, all tumors were positive for at least one endothelial marker (factor VIII-related antigen [FVIII-RAg], CD34, and/or CD31). Treatment modalities included hepatic resection or transplantation. Although the metastatic rate in this series was 27%, the prognosis is considered much more favorable than that of other hepatic malignancies. Twenty-six patients (43%) survived ≥ 5 years; 2 patients were alive and well at last follow-up after 23 and 27 years, respectively. Twenty-six of 60 patients (43%) died of their disease, 1 of whom died 28 years after discovery of her tumor. In an attempt to predict behavior of the tumor, several histologic parameters were evaluated using univariate analysis. No significant correlation was found with mitoses, Glisson's capsule infiltration, or nuclear atypia. High cellularity was significantly correlated with a poor clinical outcome (P = 0.00012), whereas the association with tumor necrosis approached significance (P = 0.057). CONCLUSIONS EHE is a very rare clinical entity. The key to diagnosis is the demonstration of cells containing FVIII-RAg. The histology of the tumor, including nuclear pleomorphism and the mitotic count, are of no value in predicting clinical outcome. High cellularity most likely is the most significant parameter predicting an unfavorable prognosis in EHE because mitotic counts often are quite low in both low grade and aggressive tumors. Further studies are needed to identify the factors responsible for the apparent dissociation between the clinical behavior and biologic characteristics of this tumor.

The importance of hemoglobin levels during radiotherapy for carcinoma of the cervix

Abstract: Background It is unclear whether blood transfusion can overcome the negative impact of anemia before or during radiotherapy (RT) in patients with carcinoma of the cervix. The objective of this retrospective study was to examine the impact of anemia and blood transfusion on 605 patients with carcinoma of the cervix treated with radical RT at 7 centers across Canada in 1989, 1990, and 1992. Methods The data collected included hemoglobin (Hgb) levels from the time of diagnosis to the end of therapy; blood transfusions administered; and identifiable patient-, tumor-, and treatment-related factors. Survival, disease free survival, and pelvic control analyses were evaluated by univariate and multivariate analysis. Results The median follow-up was 41 months (range, 0-92 months). Presenting Hgb level, average weekly nadir Hgb (AWNH) during RT, and blood transfusion were correlated significantly with local control, disease free survival, and overall survival on univariate analysis. However, the AWNH remained significant on multivariate analysis, whereas Hgb at presentation and blood transfusion did not. The 5-year survival was 74% for patients with an AWNH >/= 120 g/L, 52% for patients with AWNH levels 110-119 g/L inclusive, and 45% for patients with AWNH levels /= 120 g/L compared with Conclusions AWNH is highly predictive of outcome for patients treated with RT for carcinoma of the cervix. Blood transfusion appears to overcome the negative prognostic effects of low presenting Hgb levels and AWNH levels.

Validation of a new scoring system for the assessment of clinical trial research of oral mucositis induced by radiation or chemotherapy

Abstract: BACKGROUND An impediment to mucositis research has been the lack of an accepted, validated scoring system. The objective of this study was to design, test, and validate a new scoring system for mucositis that can be used easily, is reproducible, and provides an accurate system for research applications. METHODS A panel of experts, convened to design an objective, simple, and reproducible assessment tool to evaluate mucositis with specific application to multicenter clinical trials, developed a scale that measured objective and subjective indicators of mucositis. Nine centers participated in the study's validation. Paired investigators at each center evaluated patients receiving chemotherapy or head and neck radiation. Objective measures of mucositis evaluated ulceration/pseudomembrane formation and erythema. Subjective outcomes of mouth pain, ability to swallow, and function were measured. Analgesia use for mouth sensitivity was recorded. RESULTS One hundred eight chemotherapy and 56 radiation therapy patients were evaluated. Seventy-eight percent of chemotherapy patients and 64% of radiation therapy patients had clinically significant mucositis. Cumulative daily mucositis scores demonstrated a high correlation among observers. Using area under the curve analysis, it was found that for chemotherapy patients, the highest correlations (correlation coefficient > 0.92) occurred for the scores that selected the three highest daily values over the course of mucositis assessment. High interobserver correlations were noted for patients receiving radiation therapy. Objective mucositis scores demonstrated strong correlation with symptoms. CONCLUSIONS The scoring system evaluated was easily used, showed high interobserver reproducibility, was responsive over time, and measured those elements deemed to be associated with mucositis. The use of concomitant symptomatic measurements appeared to be unnecessary. Cancer 1999;85:2103–13. © 1999 American Cancer Society.

Two hundred eighty-six cases of parathyroid carcinoma treated in the U.S. between 1985-1995 : A National Cancer Data Base Report

Abstract: BACKGROUND In combination with other Commission on Cancer programs, the National Cancer Data Base (NCDB), a national electronic registry system currently capturing > 60% of incident cancers in the U. S., offers a working example of voluntary, accurate, cost-effective “outcomes management” on a both a local and national scale. In addition, it is proving to be of particular value in capturing clinical information concerning rare cancers. METHODS For accession years 1985–1995, the NCDB captured prospectively collected demographic, stage, treatment, and outcome information for a national hospital-based sample of 286 parathyroid carcinoma cases (0.005 % of the total NCDB cancer cases). This report describes clinical and demographic features as well as patterns of care and 5-year and 10-year relative survival rates. RESULTS The NCDB's 10-year accrual of parathyroid carcinoma cases exceeded the cumulative number reported in the English literature though 1991. Gender distribution was equal. The authors were unable to detect any disproportionate clustering by race, income level, or geographic region. Treatment overwhelmingly was surgical. The data from the current study suggest that neither tumor size nor lymph node status are significant prognostic factors. Overall relative survival at 5 years and 10 years was 85.5% and 49.1%, respectively. CONCLUSIONS At 5 years of follow-up, and possibly beyond, neither tumor size nor lymph node status were found to be significant prognostic factors and basing a staging system on them would be useless. Although complete, en bloc resection of all tumor represents the best opportunity for cure, a substantial proportion of patients fail to receive such treatment. The authors speculate that the rarity of this condition and late intraoperative recognition occasionally prevent optimal treatment.

Paclitaxel in the treatment of patients with angiosarcoma of the scalp or face.

Abstract: BACKGROUND Angiosarcomas are rare tumors. Based on a complete response observed in a patient with angiosarcoma of the scalp treated with paclitaxel in a Phase II trial, the authors treated a cohort of patients with angiosarcoma of the scalp or face with paclitaxel as single agent. METHODS The authors identified nine patients with angiosarcoma of the scalp or face treated at Memorial Sloan-Kettering Cancer Center with paclitaxel between January 1992 and December 1998. Various paclitaxel schedules were used over 1, 3, and 24 hours. RESULTS Of the 9 patients, 8 had major responses (4 partial responses and 4 clinical complete responses) and 1 had a minor response, for a major response rate of 89%. The median duration of response was 5 months (range, 2–13 months). Neutropenia and peripheral neuropathy were the most frequent dose-limiting toxicities. No deaths were attributed to therapy. CONCLUSIONS Paclitaxel as a single agent has substantial activity against angiosarcoma of the scalp or face, even in patients previously treated with chemotherapy or radiation therapy. Further investigation is warranted to define the optimal treatment dose and schedule. Cancer 1999;86:2034–7. © 1999 American Cancer Society.

The management of unicentric and multicentric Castleman's disease: a report of 16 cases and a review of the literature.

Abstract: BACKGROUND Castleman's disease (CD), or angiofollicular lymph node hyperplasia, creates both diagnostic and therapeutic dilemmas for most physicians. For patients with this rare and poorly understood disease, the optimal therapy is unknown. The authors report their experience during the years 1986–1997 with this uncommon clinicopathologic entity. METHODS Sixteen patients with a histologic diagnosis of CD were identified in the pathology database. Unicentric disease was defined as a solitary mass. Multicentric disease compromised patients with widespread lymphadenectomy. Clinical, radiologic, and laboratory data were analyzed to evaluate treatment response. RESULTS The study group consisted of 16 patients classified into 3 clinicopathologic groups: hyaline-vascular, plasma cell, and “mixed.” Of those patients who underwent complete surgical excision of a unicentric hyaline-vascular CD mass (n = 8), all remain symptom free without clinical or radiographic recurrence. Two patients remain asymptomatic following partial resection or radiation therapy for an unresectable unicentric hyaline-vascular CD mass. Two patients with multicentric hyaline-vascular CD are currently in complete remission following adjuvant therapy. Multicentric plasma cell CD was present in a single patient. This patient (who underwent surgical and systemic therapy) died of disease within 4 months of presentation. Three patients with unicentric hyaline-vascular/plasma cell-CD remain symptom free following either complete resection or observation. CONCLUSIONS The authors recommend surgical resection for patients with the unicentric variant of CD. Surgical removal of a unicentric mass of hyaline-vascular or hyaline-vascular/plasma cell type is curative. Partial resection, radiotherapy, or observation alone may avoid the need for excessively aggressive therapy. Patients with multicentric disease, either hyaline-vascular or plasma cell type, do not benefit from surgical management and should be candidates for multimodality therapy, the nature of which has yet to be defined.

Vascular endothelial growth factor in the sera and effusions of patients with malignant and nonmalignant disease

Abstract: BACKGROUND Clinical data clearly indicate a correlation between tumor neovascularization, aggressiveness of tumor growth, and metastatic spread. One of the key factors capable of stimulating tumor angiogenesis is vascular endothelial growth factor (VEGF). Using an immunoassay for VEGF, we assessed the levels of soluble VEGF in the sera and effusions of patients with malignant and nonmalignant disease as well as in the sera of healthy controls. METHODS Using a sandwich enzyme-linked immunoadsorbent assay, the concentration of VEGF was measured in serum specimens (n = 445) and effusions (n = 56) collected from a total of 212 patients with various types of cancer, 88 patients with nonmalignant disease, and 145 healthy individuals. RESULTS Low and rather stable levels of VEGF were detected in the serum of healthy individuals (median, 294 pg/mL; range, 30–1752 pg/mL; 95th percentile, 883 pg/mL). Compared with healthy individuals, serum levels in patients with acute infections were elevated (P = 0.03), whereas patients with chronic cirrhosis had lower serum VEGF levels. Among patients with various types of neoplasia, VEGF serum levels in patients with ovarian or gastrointestinal carcinoma were significantly higher than in healthy individuals. Moreover, VEGF concentrations in sera from patients with metastatic disease were higher than in sera from patients with localized tumors. Maximum serum concentrations of VEGF (median, 1022 pg/mL; range, 349–7821 pg/mL) were found in patients with metastatic ovarian carcinoma. Median VEGF levels (and ranges) in malignant effusions were up to 10-fold higher than in matched serum samples: 5528 pg/mL (468–49269 pg/mL) in ovarian carcinoma, 885 pg/mL (77–14,337 pg/mL) in breast carcinoma, and 813 pg/mL (372–18,331 pg/mL) in gastrointestinal carcinoma. In contrast, ascitic fluid from patients with cirrhosis contained only 303 pg/mL (median, range 116–676 pg/mL) of VEGF, corresponding to the low serum levels in this patient group. CONCLUSIONS Depending on the tumor type, elevated levels of VEGF are detectable in the serum of only 0–20% of patients with localized cancer but in 11–65% of patients with metastatic cancer. Of cytology-proven malignant ascites or peritoneal exudates from various malignancies, 46–96% show VEGF levels above the upper limit (95th percentile, 676 pg/mL) of nonmalignant ascites. Maximum VEGF concentrations in malignant effusions indicate abundant local release of VEGF within the pleural or peritoneal cavity. These results suggest that VEGF might play an important role in tumor progression and the formation of malignant effusions. Further studies are warranted to determine the clinical value of soluble VEGF as a tumor marker, a prognostic factor, and a surrogate indicator of tumor angiogenesis.

A randomized comparison of indwelling pleural catheter and doxycycline pleurodesis in the management of malignant pleural effusions.

Abstract: BACKGROUND The purpose of this study was to compare the effectiveness and safety of a chronic indwelling pleural catheter with doxycycline pleurodesis via tube thoracostomy in the treatment of patients with recurrent symptomatic malignant pleural effusions (MPE). METHODS In this multi-institutional study conducted between March 1994 and February 1997, 144 patients (61 men and 83 women) were randomized in a 2:1 distribution to either an indwelling pleural catheter or doxycycline pleurodesis. Patients receiving the indwelling catheter drained their effusions via vacuum bottles every other day or as needed for relief of dyspnea. RESULTS The median hospitalization time was 1.0 day for the catheter group and 6.5 days for the doxycycline group. The degree of symptomatic improvement in dyspnea and the quality of life was comparable in each group. Six of 28 patients who received doxycycline (21%) had a late recurrence of pleural effusion, whereas 12 of 91 patients who had an indwelling catheter (13%) had a late recurrence of their effusions or a blockage of their catheter after the initially successful treatment (P = 0.446). Of the 91 patients sent home with the pleural catheter, 42 (46%) achieved spontaneous pleurodesis at a median of 26.5 days. CONCLUSIONS A chronic indwelling pleural catheter is an effective treatment for the management of patients with symptomatic, recurrent, malignant pleural effusions. When compared with doxycycline pleurodesis via tube thoracostomy, the pleural catheter requires a shorter hospitalization and can be placed and managed on an outpatient basis.

The natural history of breast carcinoma: what have we learned from screening?

Abstract: BACKGROUND The availability of breast carcinoma data from trials of mammographic screening provides an opportunity to study the natural history of breast carcinoma. METHODS The Swedish Two-County study is a randomized, controlled trial of mammographic screening for breast carcinoma in which 77,080 women were randomized to receive an invitation to mammographic screening and 55,985 were randomized to receive no invitation. During the trial, a total of 2468 breast carcinoma cases were diagnosed. The authors examined the effect of screening on the pathologic attributes of the tumors diagnosed, mortality and survival from breast carcinoma, and the consequences of arresting tumor development by screening. RESULTS Screening reduces mortality from breast carcinoma largely through its effect in detecting tumors at a smaller size, decreasing the probability of lymph node metastases, and reducing the opportunity for worsening of the grade of malignancy of the tumor. CONCLUSIONS Breast carcinoma is not a systemic disease at its inception, but is a progressive disease and its development can be arrested by screening. The point at which the tumor's progression is arrested is crucial. Detection of small (<15 mm) and lymph node negative invasive tumors will save lives and confer an opportunity for less radical treatment. Tumor progression in the preclinical phase occurs more rapidly in women age <50 years, suggesting the need for a shorter screening interval for this group.

Ten-year disease free survival after transperineal sonography-guided iodine-125 brachytherapy with or without 45-Gray external beam irradiation in the treatment of patients with clinically localized, low to high Gleason grade prostate carcinoma.

Abstract: BACKGROUND The authors report observed 10-year brachytherapy results in the treatment of 152 consecutive patients with clinically organ-confined prostate carcinoma. METHODS One hundred and fifty-two consecutive patients with T1-T3, low to high Gleason grade, prostate carcinoma were treated between January 1987 and June 1988 at Northwest Hospital in Seattle, Washington. Their median age was 70 years (range, 53-92 years). Of these 152 patients, 98 (64%) received an iodine-125 implant alone (Group 1), and the remaining 54 patients (36%), who were judged to have a higher risk of extraprostatic extension, also were treated with 45 gray (Gy) of external beam irradiation to the pelvis (Group 2). No patient underwent lymph node sampling, and none received androgen ablation therapy. Multivariate regression and the Mann-Whitney rank sum test were used for statistical analysis. Preoperative patient data with associated success or failure outcomes at 10 years after treatment were used for training and validating a back-propagation neural network prediction program. RESULTS The average preoperative prostate specific antigen (PSA) value, clinical stage, and Gleason grade were 11.0 ng/mL, T2, and 5, respectively. The median posttreatment follow-up was 119 months (range, 3-134 months). Overall survival 10 years after treatment was 65%. At last follow-up only 3 of the 152 patients (2%) had died of prostate carcinoma. Ninety-seven patients (64%) remained clinically and biochemically free of disease at 10 years of follow-up and had an average PSA value of 0.18 ng/mL (range, 0.01-0.5 ng/mL). In these patients a period of 42 months was required to reach the average PSA (0.5 ng/mL). The median to last PSA follow-up was 95 months (range, 3-134 months). Postoperative needle biopsies were negative in 56% of patients, positive in 15% of patients, and not available in 29% of patients. Only 6% of patients developed bone metastasis. At 10 years there was no statistically significant difference in treatment outcome between patients who received iodine-125 alone, and those who received iodine-125 with 45-Gy external beam irradiation (P = 0.08). Nevertheless, in these two groups preoperative PSA, stage, and Gleason grade were significantly different (P < 0.01). In the artificial neural network analysis, pretreatment serum PSA was the most accurate predictor of disease-free survival. CONCLUSIONS Percutaneous prostate brachytherapy is a valid and efficient option for treating patients with clinically organ-confined, low to high Gleason grade, prostate carcinoma. Observed 10-year follow-up documents serum PSA levels superior to those reported in several published external beam irradiation series, and comparable to those published in a number of published radical prostatectomy series.

Incidence and distribution pattern of pelvic and paraaortic lymph node metastasis in patients with Stages IB, IIA, and IIB cervical carcinoma treated with radical hysterectomy.

Abstract: BACKGROUND The incidence and distribution pattern of retroperitoneal lymph node metastasis in patients with cervical carcinoma should be investigated based on data from systematic pelvic lymph node (PLN) and paraaortic lymph node (PAN) dissection, so that a basis can be established for determining the site of selective lymph node dissection or sampling. METHODS A total of 208 patients with Stages IB, IIA, and IIB cervical carcinoma who underwent radical hysterectomy and systematic pelvic and PAN dissection were investigated for lymph node metastasis and histopathologic risk factors for lymph node metastasis. RESULTS Fifty-three patients (25.5%) had lymph node metastasis. The obturator lymph nodes were most frequently involved, with a rate of 18.8% (39/208). Forty-nine of 53 node-positive patients had lymph node metastasis in the obturator, internal iliac, or common iliac lymph nodes. Of 26 solitary lymph node metastases confined to one node group, 18 were in the obturator, 3 in the internal iliac, 3 in the parametrial, and 2 in the common iliac lymph nodes. A multiple logistic regression analysis revealed that deep cervical stromal invasion and lymph-vascular space invasion were related to PLN metastasis. It was also shown that metastasis to bilateral PLNs (excluding the common iliac lymph nodes) as well as metastasis to the common iliac lymph nodes were significantly related to PAN metastasis. CONCLUSIONS The results of this study suggest that the obturator lymph nodes can be sentinel lymph nodes of cervical carcinoma. PAN metastasis appears to occur secondarily to wide-spread PLN metastasis. These results provide a basis for determining the site of selective lymph node dissection and for estimating the existence of PAN metastasis from the pattern of metastasis in PLN in patients with cervical carcinoma.

Determinants of caregiving experiences and mental health of partners of cancer patients.

Abstract: BACKGROUND. Research regarding informal caregiving showed considerable individual variation in responses to cancer caregiving. The current longitudinal study examined determinants of caregiver outcomes in terms of caregiver experiences at 3 months and caregiver's mental health at 6 months after hospital discharge. It included both negative and positive dimensions of caregiving outcomes. METHODS. One hundred forty-eight patients with newly diagnosed colorectal carcinoma and their partners were included. Caregiver experiences were assessed by the Caregiver Reaction Assessment Scale, which contains four negative subscales (disrupted schedule, financial problems, lack of family support, and loss of physical strength) and one positive subscale (self-esteem). The mental health of the caregiver was assessed in terms of depression and quality of life. Possible determinants of the caregiver's experiences and mental health were categorized according to characteristics of the caregiver, the patient, and the care situation. Caregiving experiences were studied as a fourth additional category of possible determinants of the caregiver's mental health. RESULTS. Each domain of the caregiving experience was explained by different factors, with total explained variances ranging between 11-46%. Negative caregiver experiences were associated with a low income, living with only the patient, a distressed relationship, a high level of patient dependency, and a high involvement in caregiving tasks. Caregivers with a low level of education and caregivers of patients with a stoma were able to derive more self-esteem from caregiving. Although caregiving may lead to depression, especially in those experiencing loss of physical strength, caregivers may sustain their quality of life by deriving self-esteem from caregiving. CONCLUSIONS. It is important that professionals involved in the ongoing care of cancer patients and their families be aware of the increasing demands made on caregivers and the specific problems and uplifts they perceive in caregiving. Professional caregivers are urged to involve informal caregivers with care explicitly and continuously. However, specific attention to those caregivers who live only with the patient, those with a low income, those with a distressed relationship, and those with a high level of patient dependency and care involvement is warranted.

Age‐related differences in the quality of life of breast carcinoma patients after treatment

Abstract: BACKGROUND The objective of this study was to compare the quality of life (QOL) of younger (≤ 50 years) versus older (> 50 years) women on recent completion of treatment of breast carcinoma. METHODS Data reported herein were obtained from a baseline assessment of 304 breast carcinoma patients. These patients were enrolled in a multiinstitutional, randomized trial testing a psychosocial telephone counseling intervention for breast carcinoma patients immediately after treatment. The assessment was made using a self-administered (mail) questionnaire, with an overall response rate of 86%. Included in this questionnaire were standardized measures of QOL using the Functional Assessment of Cancer Therapy-Breast instrument, the Center for Epidemiologic Studies Depression Scale, and the Impact of Event Scale. RESULTS Comparisons of baseline data analyzed according to age approximating menopausal status (≤ 50 years and > 50 years) indicated that younger women reported significantly greater QOL disturbance. QOL was significantly worse for younger women globally (P = 0.021), and with regard to domains of emotional well-being (P = 0.0002) and breast carcinoma specific concerns (P = 0.022). Furthermore, symptoms of depression (P = 0.041) and disease specific intrusive thoughts (P = 0.013) were significantly worse for younger women. No significant sexual dysfunction or body image differences were noted. CONCLUSIONS Results from this analysis suggest that younger women with breast carcinoma should be considered to be at high risk for QOL disruption and significant clinical distress. Targeted interventions for this cohort are recommended. Cancer 1999;86:1768–74. © 1999 American Cancer Society.

The impact of nutritional status on the prognoses of patients with advanced head and neck cancer

Abstract: BACKGROUND. Malnutrition has been recognized as a poor prognostic indicator for cancer treatment-related morbidity and mortality in general, and it is reported to affect 30-50% of all patients with head and neck cancer. In this study, the correlation of nutritional status with 3-year survival was studied prospectively in 64 patients with T2-T4 carcinomas of the head and neck who were treated surgically with curative intent; the surgery was often followed by radiotherapy. METHODS. All patients underwent nutritional screening according to six different parameters on the day prior to surgery. Overall and disease specific survival analyses were performed with a follow-up period of at least 3 years. Survival analyses were performed with the log rank test and the Cox proportional hazards model. RESULTS. Lymph node stage, nonradical resection margins, and occurrence of major postoperative complications were demonstrated to affect disease specific survival for the group as a whole. None of the investigated nutritional parameters were correlated with survival. When men and women were analyzed separately, however, a preoperative weight loss of >5% did have a prognostic value for men. The combination of male gender, preoperative weight loss, and major postoperative complications were related to early death. CONCLUSIONS. Apart from the well-known prognostic parameters lymph node status (T classification) and status of surgical margins, preoperative weight loss and occurrence of major postoperative complications were also found to have a negative effect on the survival of male patients undergoing surgery for advanced head and neck cancer.

Long term tolerance of high dose three-dimensional conformal radiotherapy in patients with localized prostate carcinoma.

Abstract: BACKGROUND The current study was undertaken to evaluate the incidence and predictors of late toxicity in patients with localized prostate carcinoma treated with high dose three-dimensional conformal radiotherapy (3D-CRT). METHODS A total of 743 patients with prostate carcinoma classified as T1c–T3 were treated with 3D-CRT that targeted the prostate and seminal vesicles. A minimum tumor dose of 64.8 gray (Gy) was given to 96 patients (13%), 70.2 Gy to 266 patients (365), 75.6 Gy to 320 patients (43%), and 81.0 Gy to 61 patients (8%). The median follow-up time was 42 months (range, 18–109 months). Late toxicity was graded according to the Radiation Therapy Oncology Group morbidity scoring scale. RESULTS Late gastrointestinal (GI) and urinary (GU) toxicities were absent or minimal (Grade 0 or 1) in 90% of patients. The 5-year actuarial likelihood of the development of Grade 2 and 3 late GI toxicities was 11% and 0.75%, respectively. A multivariate analysis identified doses ≥75.6 Gy (P < 0.001), history of diabetes mellitus (P = 0.01), and the presence of acute GI symptoms during treatment (P = 0.02) as independent predictors of Grade ≥2 late GI toxicity. The 5-year actuarial likelihood of the development of Grade 2 and 3 late GU toxicities was 10% and 3%, respectively. Doses ≥75.6 Gy (P = 0.008) and acute GU symptoms (P < 0.001) were independent predictors of Grade ≥2 late GU toxicity. Among 544 patients who were potent before treatment (73% of all patients), 211 (39%) became impotent after 3D-CRT. The 5-year actuarial risk of potency loss was 60%. Doses ≥75.6 Gy (P < 0.001) and the use of neoadjuvant androgen deprivation (P = 0.01) were independent predictors of posttreatment erectile dysfunction. CONCLUSIONS The incidence of severe late complications after high dose 3D-CRT was minimal. Radiation doses ≥75.6 Gy and the presence of acute treatment-related symptoms during 3D-CRT correlated with a higher incidence of Grade ≥2 late GI and GU toxicities. In addition to higher doses, the use of androgen deprivation therapy increased the likelihood of permanent impotence in these patients. Intensity-modulated radiotherapy, which makes it possible to enhance the conformality of the dose distribution, has recently been implemented in an attempt to reduce the incidence of moderate grade toxicities in patients receiving high dose 3D-CRT.

Extremity and Trunk Desmoid Tumors: A Multifactorial Analysis of Outcome

Abstract: BACKGROUND The natural history of desmoid tumors remains an enigma. Previous reports attempting to identify their biology have included recurrent and primary tumors as well as tumors from both intra- and extra-abdominal sites. The purpose of this study was to analyze patients with primary extremity and trunk desmoid tumors treated and followed at a single institution and to determine factors influencing disease free survival. METHODS Between July 1982 and June 1997, 189 patients with extremity and superficial trunk desmoid tumors were treated and followed prospectively. Of these, 105 presented with primary disease and formed the basis of this study. RESULTS The median follow-up for the entire group of patients was 49 months; it was 46 months for patients who did not develop a local recurrence. During this time, 24 patients (23%) had a local recurrence. No patients died of disease. The 2-year and 5-year local recurrence free survival rates were 80% and 75%, respectively. None of the prognostic factors analyzed, including age, gender, depth of tumor, size of tumor, or tumor site, were significant for predicting local recurrence. Moreover, positive resection margins were not predictive of recurrence. The selective use of adjuvant radiation therapy did not influence the rate of local recurrence regardless of the margin status. CONCLUSIONS Attempts to achieve negative resection margins may result in unnecessary morbidity and may not prevent local recurrence. Operations that preserve function and structure should be the primary goal, because the presence of residual disease cannot be clearly shown to impact adversely on 5-year disease free or overall survival.

Male breast carcinoma: a review of 229 patients who presented to the Princess Margaret Hospital during 40 years: 1955-1996.

Abstract: BACKGROUND A single-institution review of clinical presentation, treatment, and outcome of male breast carcinoma was conducted. METHODS Data obtained by chart review of 229 cases were analyzed with respect to clinical presentation, treatment choice, significant prognostic factors, and survival. The patients were analyzed both as a single cohort and as four cohorts grouped according to decade of diagnosis. RESULTS Presentation occurred at a median age of 63 years, most often with a self-detected lump. Pathology consisted of subtypes similar to those of female breast carcinoma. The majority of tumors were larger than 2 cm in greatest dimension. Lymph node status, hormone receptors, and histologic and nuclear grade were underreported. Primary, adjuvant, and advanced disease treatment practices were reviewed over time. The 5-year disease free survival (DFS), overall survival (OS), and local control were 47%, 53%, and 91%, respectively. No difference in outcome by decade of diagnosis was observed. Negative lymph nodes and adjuvant hormone treatment predicted for better DFS and OS. Younger age and Stage 0 also predicted for better OS. CONCLUSIONS Compared with data from female breast carcinoma patients, 5-year OS for this series was low; however, when these patients were separated by lymph node status, survival was similar for those with axillary lymph node metastases. Despite a change in standard primary surgical treatment and an increased use of chemotherapy and hormone therapy over the study period, no difference in outcome was observed among these males. In the absence of prospective, randomized clinical trials, collection of comprehensive data on the presentation and management of male breast carcinoma may help to optimize clinical care.

The American College of Surgeons Commission on Cancer and the American Cancer Society. Adenocarcinoma of the small bowel: review of the National Cancer Data Base, 1985-1995.

Abstract: BACKGROUND Small bowel adenocarcinoma (SBA) accounts for 2% of gastrointestinal (GI) tumors and 1% of GI cancer deaths. The objective of this study was to review the National Cancer Data Base (NCDB) to identify case-mix characteristics, patterns of treatment, and factors influencing survival of patients with SBA. METHODS NCDB data from patients diagnosed with primary SBA between 1985–1995 were analyzed. Chi-square statistics were used to compare differences between groups. Disease specific survival (DSS) was calculated using the life table method for patients diagnosed between 1985–1990; univariate differences in survival were compared using the Wilcoxon statistic, and multivariate analyses were performed using a Cox regression model. RESULTS There were 4995 SBA cases reported to the NCDB between 1985–1995, 55% of which occurred in the duodenum, 18% in the jejunum, 13% in the ileum, and 14% in nonspecified sites. The overall 5-year DSS was 30.5%, with a median survival of 19.7 months. By multivariate analysis, factors significantly correlated with DSS included patient age, tumor site, disease stage, and whether cancer-directed surgery was performed. CONCLUSIONS SBA is found most commonly in the duodenum, and patient DSS is reduced at this site compared with those patients with jejunal or ileal tumors. This reduction in survival was associated with a lower percentage of cancer-directed surgery. Patients age > 75 years had a reduced DSS and more duodenal tumors, and were less frequently treated by cancer-directed surgery than their younger counterparts. This study reflects the experience with SBA from a large cross-section of U.S. hospitals, allowing for the identification of prognostic factors and providing a reference with which results from single institutions may be compared.
