TL;DR: The results of the analyses suggest that disease progression to distant sites does not occur exclusively via the axillary lymph nodes, but rather that lymph node status serves as an indicator of the tumor's ability to spread.
Abstract: Two of the most important prognostic indicators for breast cancer are tumor size and extent of axillary lymph node involvement. Data on 24,740 cases recorded in the Surveillance, Epidemiology, and End Results (SEER) Program of the National Cancer Institute were used to evaluate the breast cancer survival experience in a representative sample of women from the United States. Actuarial (life table) methods were used to investigate the 5-year relative survival rates in cases with known operative/pathologic axillary lymph node status and primary tumor diameter. Survival rates varied from 45.5% for tumor diameters equal to or greater than 5 cm with positive axillary nodes to 96.3% for tumors less than 2 cm and with no involved nodes. The relation between tumor size and lymph node status was investigated in detail. Tumor diameter and lymph node status were found to act as independent but additive prognostic indicators. As tumor size increased, survival decreased regardless of lymph node status; and as lymph node involvement increased, survival status also decreased regardless of tumor size. A linear relation was found between tumor diameter and the percent of cases with positive lymph node involvement. The results of our analyses suggest that disease progression to distant sites does not occur exclusively via the axillary lymph nodes, but rather that lymph node status serves as an indicator of the tumor's ability to spread.

TL;DR: Dietary and lifestyle characteristics were evaluated in relation to subsequent prostatic cancer risk in a cohort of approximately 14,000 Seventh‐day Adventist men who completed a detailed lifestyle questionnaire in 1976 and who were monitored for cancer incidence until the end of 1982.
Abstract: Dietary and lifestyle characteristics were evaluated in relation to subsequent prostatic cancer risk in a cohort of approximately 14,000 Seventh-day Adventist men who completed a detailed lifestyle questionnaire in 1976 and who were monitored for cancer incidence until the end of 1982. During the 6-year follow-up period, 180 histologically confirmed prostatic cancers were detected among some 78,000 man-years of follow-up. Increasing educational attainment was associated with significantly decreased risk of prostate cancer in this study; age at first marriage was also inversely associated with risk, although this was not significant. There was no relationship between body mass index (as measured by Quetelet's Index) and risk. A history of prostate “trouble” was associated with a 60% increase in risk which was highly significant. Although there were suggestive relationships between increasing animal product consumption and increased risk, these results did not persist after accounting for the influence of fruit and vegetable consumption. Nor was exposure to the vegetarian lifestyle during the childhood years associated with alterations in subsequent risk. However, increasing consumption of beans, lentils and peas, tomatoes, raisin, dates, and other dried fruit were all associated with significantly decreased prostate cancer risk.

TL;DR: The Third National Wilms' Tumor Study as discussed by the authors sought to reduce treatment for low-risk patients and find better chemotherapy for those at high risk for relapse by randomized treatment regimens.
Abstract: The Third National Wilms' Tumor Study sought to reduce treatment for low-risk patients and find better chemotherapy for those at high risk for relapse. Eligible patients (1439) were randomized according to stage (I-IV) and histology (favorable [FH] or unfavorable [UH]), and contributed data to survival and relapse-free survival (RFS) analyses. Four-year (postnephrectomy) survival percentages and randomized treatment regimens for low-risk patients were 96.5% for 607 Stage I/FH patients who received dactinomycin (Actinomycin D [AMD], Merck Sharp & Dohme, West Point, PA) and vincristine (VCR) for 10 weeks versus 6 months; 92.2% for 278 Stage II/FH patients; and 86.9% for 275 Stage III/FH patients who received AMD + VCR +/- Adriamycin (ADR, Adria Laboratories, Columbus, OH) for 15 months. Stage II/FH patients also had either zero or 2000 cGy irradiation (RT) postoperatively and Stage III/FH patients either 1000 or 2000 cGy. Four-year survival was 73.0% for 279 high-risk patients (any Stage IV, all UH) who received postoperative radiation therapy (RT) and AMD + VCR + ADR +/- cyclophosphamide (CPM). Statistical analysis of survival and RFS experience shows that the less intensive therapy does not worsen results for low-risk patients and CPM does not benefit those at high risk.

TL;DR: Although 68% of CR patients have relapsed, CR median survival will exceed 38 months compared with 11 months for partial (36%) and minor (6%) responders, and 8 months for nonresponders: 2‐year and 3‐year survivals were 68% and 55%, respectively, versus 0% to 7% for the remaining patients.
Abstract: Of 133 patients with advanced urothelial tract cancer given methotrexate (MTX), vinblastine (VBL), Adriamycin (ADR) (doxorubicin; Adria Laboratories, Columbus, OH), and cisplatin (DDP) (M-VAC regimen), significant tumor regression occurred in 72% +/- 8% of 121 with transitional cell carcinoma (TCC) evaluable for response. Complete remission (CR) was achieved in 36% +/- 9% of patients, of whom 11% required the addition of surgical resection of residual disease. Although 68% of CR patients have relapsed, CR median survival will exceed 38 months compared with 11 months for partial (36%) and minor (6%) responders, and 8 months for nonresponders: 2-year and 3-year survivals were 68% and 55%, respectively, versus 0% to 7% for the remaining patients. Sixteen percent of responders developed brain lesions, half of whom had no systemic relapse at the time of progression. Three patients with non-TCC histologies did not respond. In 32 patients who had pathologic restaging, the clinical (T) understaging (T less than pathologic [P] restaging) error was 35%. Although all metastatic sites showed evidence of tumor regression, CR was noted more frequently in lung, in intraabdominal lymph nodes and masses, and in bone (24% to 35%); the rate for hepatic lesions was 15%. There were 52% of 21 N3-4M0 patients who achieved CR versus 33% of 100 with N0-+M+ lesions. Toxicity was significant with 4 (3%) drug-related deaths, 25% incidence of nadir sepsis, 58% greater than or equal to 3+ myelosuppression, and 49% with mucositis. Responsiveness of metastasis in various sites, patterns of relapse, and the usefulness of the new CR response criteria are reported, as is the current status of cisplatin and methotrexate combination regimens.

TL;DR: Surgical intervention for gastrointestinal complications in peritoneal carcinomatosis can provide significant palliation, with a few exceptions such as in patients with pancreatic or gastric carcinoma, ascites, and poor performance status.
Abstract: Regional recurrence of malignant tumors in the peritoneal cavity usually signifies a poor prognosis for the host and often results in gastrointestinal complications requiring surgical intervention. One hundred patients with nongynecological malignancies found with peritoneal carcinomatosis were followed prospectively. The most common primary tumors were colorectal (N = 45) and pancreatic (N = 20) carcinoma. When associated with pancreatic carcinoma, 65% of patients had liver metastases and 60% had ascites. The presence of ascites was associated with poor survival, with no patient surviving past 30 days. Ascites was also a sign of poor prognosis in patients with colorectal carcinoma. Among possible prognostic factors in colorectal carcinoma patients, only disease-free interval, presence of lung metastases, and ascites showed statistically significant correlations with survival. Peritoneal carcinomatosis in sarcoma (N = 7) and breast cancer (N = 6) patients had median survival of 12 and 7 months, respectively. Surgical intervention for gastrointestinal complications in peritoneal carcinomatosis can provide significant palliation, with a few exceptions such as in patients with pancreatic or gastric carcinoma, ascites, and poor performance status.

TL;DR: Nuclear grade would appear to identify subsets of DCIS more likely to produce local failure after tylectomy alone, with duct carcinoma in situ with high‐grade nuclear morphology and comedo‐type necrosis associated with a 19% local recurrence rate after an average interval of 26 months.
Abstract: Seventy-nine patients with mammographically detected foci of duct carcinoma in situ (DCIS) of histologically confirmed extents of 25 mm or less, were treated by tylectomy without irradiation or axillary dissection. Adequacy of excision was confirmed histologically, by radiographic-pathologic correlation and by postoperative mammographic examination. Eight patients (10.1%) have recurred locally in the immediate vicinity of the biopsy site. Four patients developed recurrent in situ disease identified mammographically, and all were initially treated by reexcision. One of these patients subsequently elected to undergo mastectomy; no residual in situ or invasive disease was detected in the breast or in axillary lymph nodes. Four patients developed recurrent invasive disease; 50% of these recurrences were detected mammographically. All patients were treated by mastectomy with node dissection. Three had confirmed minimal invasive carcinomas and were N0, one patient had a 13-mm invasive lobular carcinoma with a single Group I micrometastasis. All patients, including those treated for a recurrence, are presently free of disease but three patients died of heart disease. Nuclear grade would appear to identify subsets of DCIS more likely to produce local failure after tylectomy alone. Duct carcinoma in situ with high-grade nuclear morphology and comedo-type necrosis was associated with a 19% local recurrence rate after an average interval of 26 months; only one of ten patients with intermediate-grade DCIS developed a local recurrence at 87 months; and none of 33 patients with DCIS of micropapillary/nonnecrotic cribriform type and low-grade nuclear morphology developed local recurrence in the follow-up period.

TL;DR: No survival advantage could be demonstrated for patients who received chemo and/or radiotherapy, although numbers are small and staging not uniform, and an evaluation by electron microscopy and immunohistochemistry cannot confirm recent claims that ASPS is a muscle tumor.
Abstract: In the period from 1923 to 1986 our pathologists examined pathologic material from 102 patients with alveolar soft-part sarcoma (ASPS). Followup clinical data is available for 91. Median followup is 7 years (range 1 month to 27 years). Local recurrence was only found if residual disease was left at the time of the original excision. Survival in those patients who presented without metastases was 77% at 2 years, 60% at 5 years, 38% at 10 years and 15% at 20 years (median 6 years). No survival advantage could be demonstrated for patients who received chemo and/or radiotherapy, although numbers are small and staging not uniform. An evaluation by electron microscopy and immunohistochemistry cannot confirm recent claims that ASPS is a muscle tumor. ASPS is an unusual neoplasm; the primary therapeutic option is aggressive surgical excision. Survival even with the development of metastases can be long.

TL;DR: Mammary recurrences were studied in 1593 patients with Stage I and II breast cancer treated by macroscopically complete tumor excision followed by megavoltage radiotherapy, including a boost to the tumor bed, showing the protracted time course and more favorable prognosis associated with the former.
Abstract: Mammary recurrences were studied in 1593 patients with Stage I and II breast cancer treated by macroscopically complete tumor excision followed by megavoltage radiotherapy, including a boost to the tumor bed (mean dose, 78 Gy). The actuarial freedom from mammary recurrence was 93% at 5, 86% at 10, 82% at 15, and 80% at 20 years. Seventy-nine percent of the recurrences were in the vicinity of the tumor bed, but with increasing time interval, an increasing percentage of recurrences was located elsewhere in the breast. A majority of recurrences after 10 years could be considered new tumors. Only ten of 181 patients with recurrence had prior or concomitant distant metastases, and 159 of 171 isolated mammary recurrences (93%) were operable. Uncorrected overall survival after operable recurrence was 69% at 5 and 57% at 10 years. Prognosis after late recurrence (after 5 years) was favorable (84% 5-year survival). Operable early recurrences retained a favorable prognosis if smaller than 2 cm and confined to the breast (74% 5-year survival). Disease-free interval and histologic grade also appeared to be important prognostic factors after early recurrence. Survival after recurrence did not depend upon the type of salvage operation. Locoregional control was 88% at 5 years after salvage mastectomy and 64% after breast-conserving salvage procedures. The role of adjuvant systemic therapy at time of local recurrence requires additional study. This experience illustrates the important differences between mammary failure and chest wall recurrence after mastectomy, in particular the protracted time course and more favorable prognosis associated with the former.

TL;DR: It is concluded that nonpolypoid early colorectal carcinomas easily progress to advanced carcinoma, and de novo carcinoma occupied about 80% of coloreCTal carcinoma.
Abstract: The growth type of early colorectal carcinoma was classified into two types. The first type is intramucosal polypoid growth (PG-Ca) and the second type nonpolypoid growth (NPG-Ca) which shows mainly massive infiltration of tumor cells below the submucosal layer. The incidence of adenoma-carcinoma sequence was 72 of 75 lesions (96.0%) in pedunculated polypoid carcinoma, and 61 of 71 lesions (85.9%) in sessile and broad-based polypoid carcinomas. Their average sizes were 15.0 and 18.7 mm, respectively. Submucosal invasive carcinoma (SM-Ca) showed a low incidence. They were detected as microscopical or scattered lesions with a few lymphatic and venous permeation. The NPG-Ca contained 32 lesions. Intramucosal carcinoma without adenoma showing slight depression consisted of ten lesions of which the average size was 5.1 mm. The other 22 lesions showed massive submucosal invasion with marked lymphatic and venous permeation. The average size was 10.3 mm being smaller than PG-Ca. Histologically, NPG-Ca was not accompanied with adenoma. The NPG-Ca arose from de novo carcinoma less than 10 mm in diameter and invaded into the submucosal layer. In advanced carcinoma, the PG-Ca showed a low incidence (21.8%), and almost all cases were of the NPG type (78.2%). The NPG advanced carcinomas increased in those over the size of 20 mm. It is concluded that nonpolypoid early colorectal carcinomas easily progress to advanced carcinoma, and de novo carcinoma occupied about 80% of colorectal carcinoma.

TL;DR: The modified SBR (MSBR), defined five new risk subgroups with statistically different risk ratios for MFS, and was the most important factor for prediction of relapse of MFS (P < 0.00001).
Abstract: We did a multivariate analysis of 1262 patients with operable, invasive ductal breast carcinoma to assess the prognostic value of the Scarff-Bloom-Richardson (SBR) histologic grading system Nodal metastasis and SBR were the two most important factors for metastasis-free survival (MFS), P = 10-9 and P = 10-5, respectively, for total study time In patients who were node negative, the SBR and International Union Against Cancer (UICC) stages were the most important for MFS (P = 4 X 10-4 and P = 003) In order to try to improve the SBR prognostic value, we first studied the three components of the SBR separately: ductoglandular differentiation proved the least predictive and nuclear pleomorphism and mitotic index the most predictive A rearrangement of the two nuclear scores alone produced higher risk values and better risk separation of patient subpopulations than SBR, and eliminated the SBR from the multivariate model This rearrangement, modified SBR (MSBR), defined five new risk subgroups with statistically different risk ratios for MFS (P = 3 X 10-8) SBR grade II (55% of patients) was separated into three MSBR groups significantly different according to MFS (P = 0008) In the patients who were node negative, MSBR replaced the SBR and was the most important factor for prediction of relapse of MFS (P less than 000001) The MSBR is more accurate and predictive than the standard SBR grade and is particularly useful when the nodal status of the patient is negative or unknown
TL;DR: There would appear to be justification for reexamining extended nodal dissection for gastric cancer in the US, although patients with both apparent and confirmed direct adjacent organ invasion can be helped by resection of those organs, extended resections of uninvolved pancreas and spleen do not improve rate of survival.
Abstract: Overall results after operations for gastric cancer in Japan are far superior to results obtained in the US and Europe. We have reviewed the Japanese literature in an effort to determine what factors explain this difference. It appears that the survival differences are due mainly to a greater frequency of early gastric cancer in Japan; meticulous histopathologic evaluation of the surgical specimens, resulting in more accurate pathologic staging; and the presumed benefit of extended nodal dissection when it extends outside of the level of node-positive disease. Although patients with both apparent and confirmed direct adjacent organ invasion can be helped by resection of those organs, extended resections of uninvolved pancreas and spleen do not improve rate of survival beyond the benefit of improved nodal dissection. Overall, there would appear to be justification for reexamining extended nodal dissection for gastric cancer in the US. Opportunities for a meaningful national study are significant.
TL;DR: The results clearly demonstrate that surgical trauma renders a nonprivileged organ susceptible to experimental metastasis formation, and that at least in this model both laser and electrocautery have similar effects.
Abstract: Influence of surgical trauma on experimental metastasis in healing wounds is investigated using a transplantable murine mammary carcinoma cell line, TA3Ha. Intravenous injection of 10(5), 10(6), and 2 x 10(6) TA3Ha cells into syngeneic Strain A mice led to liver or kidney tumor development in none of the 96, ten, and ten mice tested, respectively. In contrast, injection of 10(5) cells into mice immediately after hepatic wedge resection performed using milliwatt carbon dioxide laser and electrocautery resulted in tumor formation at the site of trauma in 21/37 (57%) and 25/52 (48%) mice, (P less than 0.001) respectively. Similar results were obtained in mice subjected to partial nephrectomy using the laser (nine of 18) and electrocautery (eight of 13). These results clearly demonstrate that surgical trauma renders a nonprivileged organ susceptible to experimental metastasis formation, and that at least in this model both laser and electrocautery have similar effects. Tumor cell injection 1, 7, and 10 days posthepatic surgery resulted in 36%, 20%, and 0% tumor formation, respectively, indicating that the earlier events in wound healing support tumor implantation and/or growth better than those later on. Frequency of tumor formation at sites of trauma in the peritoneum induced by scalpel blade, laser, and electrocautery were 28%, 50% and 82%, respectively. Peritoneal tumors were seen in 33% of the nonsurgical mice. Skin incisions induced with the three above probes had little influence on experimental metastasis formation. Thus the influence of trauma on tumor formation is not uniform in every organ.
TL;DR: Chemotherapy side effects, patient distress, and patient‐practitioner communication were evaluated in an inception sample of 238 patients with breast cancer or malignant lymphoma and communication between patient and practitioner was found to be inadequate.
Abstract: Chemotherapy side effects, patient distress, and patient-practitioner communication were evaluated in an inception sample of 238 patients with breast cancer or malignant lymphoma. Participants were interviewed at five points during their first six cycles of therapy, and a subsample kept brief daily symptom diaries. Nausea, hair loss, and tiredness were each experienced by more than 80% of patients. By cycle 6, 46% of patients had thoughts about quitting therapy, but only a few had told medical staff. Patients' ratings of the objective difficulty of treatment increased over time, varied by treatment regimen, and were predicted by the experience of side effects, with the number of different side effects serving as the best predictor. In contrast, emotional distress was less sensitive to the directly assessable characteristics of treatment. Communication between patient and practitioner was found to be inadequate in a number of respects (i.e., patients did not fully anticipate the toxicities of treatment and did not report their concerns to medical staff). Communication may be impeded by inaccuracies in a patient's recall of treatment difficulties and by a patient's inability or unwillingness to attend to all presented information. More frequent opportunities for patient-practitioner discussion are necessary.
TL;DR: Serum AFP values at the time of presentation are not only of diagnostic value, but also of prognostic significance in patients with HCC.
Abstract: Clinical features of hepatocellular carcinoma (HCC) with normal serum alpha-fetoprotein (AFP) levels were compared with those of AFP-positive cases. A total of 606 patients were divided into four groups based on their serum AFP levels at the time of diagnosis: group 1 (less than or equal to 20 ng/ml, N = 125), group 2 (20-1000 g/ml, N = 256), group 3 (1000-10000 ng/ml, N = 149), and group 4 (greater than 10000 ng/ml, N = 76). Increasing prevalence of group 1 patients and decreasing prevalence of group 4 were noted during the last 9 years. The proportion of hepatitis B virus-positive cases was significantly lower in group 1 than in group 4. The serum glutamic oxaloacetic transaminase/serum glutamic pyruvic transaminase ratio was found to be significantly higher in group 4 than in group 1 regardless of the size of the tumors. The survival rates were compared among the four groups in size matched cases since the size of the tumor significantly influenced their prognosis. The median survival in relatively small HCC patients (less than or equal to 5 cm in diameter, N = 199) were 24.6 months for group 1, 20.6 months for group 2, and 13.7 months for group 3 patients; and those in large HCC (greater than 50% in the proportion of the tumor area, N = 200) were 15.1 months for group 1, 6.3 months for group 2, 5.8 months for group 3, and 5.2 months for group 4. Thus, serum AFP values at the time of presentation are not only of diagnostic value, but also of prognostic significance in patients with HCC.
TL;DR: Elderly women do as well as younger patients in survival time for localized and regional stages of breast cancer; for distant disease, they fare worse; results emphasize the need to focus on elderly women for screening, early detection, diagnostic evaluation, and therapy.
Abstract: Over 43% of the newly diagnosed breast cancers in the US occur in women 65 years or older. Yet little attention is devoted to the age-associated aspects of this malignancy. This study uses data on more than 125,000 women diagnosed from 1973 to 1984 to examine the influence of advancing age on breast cancer. The National Cancer Institute's Surveillance, Epidemiology, and End Results Program provides information on disease stage, surgery, histologic type, and survival time to compare and contrast women in all age groups. Women who present initially with distant disease are more likely to be elderly. Certain surgical procedures are used less frequently for older women. No unusual age variations in histologic features are noted. Elderly women do as well as younger patients in survival time for localized and regional stages of breast cancer; for distant disease, they fare worse. Results emphasize the need to focus on elderly women for screening, early detection, diagnostic evaluation, and therapy.
TL;DR: With adequate sampling, the finding of 100% sensitivity in the diagnosis of malignant neoplasms by FNA cytology reaffirms its role as the procedure of choice in the initial screening of thyroid nodules.
Abstract: Smears obtained from 795 patients with suspicious thyroid nodules by fine needle aspiration (FNA) of the thyroid gland were seen over a 5-year period at the UCLA Center for the Health Sciences. From 72 patients who underwent subsequent surgical excision of their nodules, inadequate or discrepant FNA diagnoses were noticed in 20 cases (27.8%). These errors could be attributed to inadequate material for diagnosis (n = 6), sampling errors (n = 2), and cytodiagnostic errors (n = 12). If the diagnosis of follicular neoplasm was treated as indeterminate for malignancy, the overall efficiency of FNA was 88.9%. All false-negative diagnoses were related to procedure (i.e., inadequate smears or missed sampling of the lesion). The frequency of inadequate smears, in turn, was strongly related to the type of physician performing the aspiration. The frequency was highest among community-based clinicians (32.4%) and lowest among hospital-based cytopathologists (6.4%). With adequate sampling, the finding of 100% sensitivity in the diagnosis of malignant neoplasms by FNA cytology reaffirms its role as the procedure of choice in the initial screening of thyroid nodules.
TL;DR: Findings indicate biphasic differentiation by cells possessing epithelial and mesenchymal characteristics and suggest myoepithelial origin or differentiation in carcinosarcoma.
Abstract: The clinical and pathologic features of 70 examples of carcinosarcoma (CS) of the breast are reported. Thirty-three neoplasms had infiltrating carcinoma, seven had in situ carcinoma, and 28 had both admixed or contiguous with the sarcomatous component. Squamous carcinoma, present in 15 neoplasms, was the exclusive epithelial component of two. The admixed carcinoma often appeared distinct from the sarcoma component; however, at high magnification transitional differentiation zones and more subtle merging of infiltrating carcinoma with sarcoma were present in most neoplasms. A total of 40 neoplasms were studied by immunohistochemistry for keratins, EMA, vimentin, S-100 protein, and actin. The sarcomatous component in 55% of CS was immunoreactive for keratin, and 98% were immunoreactive for vimentin. A majority were also immunoreactive for actin (77%), and S-100 protein (55%). Ultrastructural examination of the sarcoma in eight neoplasms yielded variable nonspecific findings compatible with sarcoma. These findings indicate biphasic differentiation by cells possessing epithelial and mesenchymal characteristics and suggest myoepithelial origin or differentiation. The cumulative 5-year survival rate for CS was 49%, worse than for other forms of metaplastic carcinoma. The respective 5-year survivals for TNM clinical Stages I, II, and III were 100%, 63%, and 35%. Of patients with axillary dissection, 26% had metastases to axillary lymph nodes with carcinoma as the most frequent component to metastasize. Metastasis was an ominous sign as 33 of 34 patients who developed metastases died from tumor. Local recurrence was not as ominous as 40% who had only local recurrence subsequently died from tumor. Size and microscopic circumscription were also significant prognostic factors.
TL;DR: Home nursing care assists patients with forestalling distress from symptoms and maintaining their independence longer in comparison to no home nursing care, suggesting that home care may also include assisting patients in acknowledging the reality of their situation.
Abstract: A randomized clinical trial was conducted to assess the effects of home nursing care for patients with progressive lung cancer One hundred sixty-six patients were assigned to either an oncology home care group (OHC) that received care from oncology home care nurses, a standard home care group (SHC) that received care from regular home care nurses, or an office care group (OC) that received whatever care they needed except for home care Patients were entered into the study 2 months after diagnosis and followed for 6 months Patients were interviewed at 6-week intervals across five occasions At the end of the study, there were no differences in pain, mood disturbance, and concerns among the three groups There were significant differences in symptom distress, enforced social dependency, and health perceptions The two home nursing care groups had less distress and greater independence 6 weeks longer than the office care group In addition, the two home nursing care groups steadily reported worse health perceptions over time Thus, it was remarkable that the office care group, which indicated more symptom distress and social dependency with time, also indicated perceptions of improved health with time These results suggest that home nursing care assists patients with forestalling distress from symptoms and maintaining their independence longer in comparison to no home nursing care Home care may also include assisting patients in acknowledging the reality of their situation
TL;DR: No relationship between tumor size and risk of local recurrence could be demonstrated, and no difference could be identified between borderline and malignant lesions, in terms both of local and distant relapse.
Abstract: Eighty-one female patients with phyllodes tumors of the breast, surgically treated from 1974 to 1983, were studied. Their age ranged from 9 to 88 years. According to histology, the series was divided into three groups, of 28 (34.5%) benign tumors, 32 (39.5%) border-line tumors, and 21 (25.9%) malignant tumors. Because ten patients were lost to follow-up, only 71 women could be evaluated. All the patients had received surgical treatment: 51 women had been treated conservatively (11 enucleations, 40 wide resections), and 20 had undergone radical operations (13 underwent total and five underwent subcutaneous mastectomies, whereas one underwent modified and one underwent radical mastectomy). The mean follow-up, for the three groups, was 106 months for benign, 84 months for borderline, and 82 months for malignant tumors; in no case was radical surgery followed by local recurrence: of 51 women conservatively treated, 14 experienced local relapse, i.e., one of 24 women with benign, ten of 22 with borderline, and three of 8 with malignant lesions. Only two of 47 patients (4.2%) with borderline or malignant tumors developed distant metastasis and died from disease. No relationship between tumor size and risk of local recurrence could be demonstrated, and no difference could be identified between borderline and malignant lesions, in terms both of local and distant relapse. Local recurrences do not appear to affect survival: as a consequence, wide resection should be the primary treatment. Enucleation is to be proscribed. Total mastectomy has been indicated for very large tumors and for local recurrences of borderline and malignant lesions. Axillary dissection is not worthwhile.
TL;DR: The clinical and histologic features of twenty cases of a type of papillary‐cystic temporal bone neoplasm are reported, which destroyed a large portion of the posterior temporal bone and included a prominent extension into the posterior cranial fossa.
Abstract: The clinical and histologic features of twenty cases of a type of papillary-cystic temporal bone neoplasm are reported. Ages of the patients ranged from 15 to 71 years. The tumors destroyed a large portion of the posterior temporal bone and included a prominent extension into the posterior cranial fossa. Patient histories indicated a slow growth rate of the lesions. Awareness of the parameters of this neoplasm, including the site of origin and probably histogenesis, may enable earlier diagnosis and more successful treatment of the tumor in the future.
TL;DR: The results help to estimate the nodal metastatic potential of early colorectal carcinomas and stress the importance of adequate pathologic evaluation in order to assess metastatic risk in these patients accurately.
Abstract: Adenomas that contain early invasive carcinoma (ACIC) represent the earliest form of clinically relevant cancer of the colorectum in most patients. In order to assess the incidence of nodal metastases of ACIC, we studied 31 patients in whom the colon was resected after endoscopic polypectomy (EP) done from 1975 to 1987. We also reviewed the pathologic features reported in individual cases and in literature series of ACIC with lymph node metastases published from 1958 to 1986. The lymph node metastatic potential of ACIC is relatively high, ranging from an average value of 8.5% in the literature of to 16.1% in our own study, and is equivalent to the range of 10%-17% that occurs in colorectal carcinomas that invade the submucosa. When an ACIC is seen in an EP specimen in which the polypectomy margin is normal, the decision as to whether the patient should enter a follow-up protocol or have radical surgical resection is determined by the assessment of the probability of the occurrence of nodal metastases. According to several authors, certain histopathologic features make it possible to distinguish between an ACIC with a high-risk of nodal metastases versus those with a low-risk. The most relevant pathologic parameters include the state of the resection margins, the grade of the invasive carcinoma, and the presence or absence of vascular invasion. Of 351 cases of ACIC that were operated on, derived from 16 literature series, 45.6% were high-risk cases and 8.5% had lymph node metastases. In our group of high-risk ACIC that had surgical resection subsequently, the lymph node metastatic rate was 35.7%. Our results help to estimate the nodal metastatic potential of early colorectal carcinomas and stress the importance of adequate pathologic evaluation in order to assess metastatic risk in these patients accurately.
TL;DR: M Mammographic and clinical tumors in the quantitative range of the incidental group (50 ducts) showed significant differences from it for all variables studied, and Histologic and quantitative study of these tumors is necessary to best guide treatment.
Abstract: Fifty-one women (29 to 75 years of age) with 55 cancers (ductal carcinoma in situ (DCIS) or ductal carcinoma in situ with microinvasion (DCISM) were studied by comparing biopsy specimens with mastectomy specimens. Presentation, histologic type, nuclear grade, microscopic duct counts, multicentricity, and microinvasion were correlated. Forty-seven percent of the cancers (26 of 55) were detected by mam-mography, 18% (ten of 55) were incidental to benign disease, and 35% (19 of 55) were palpable or exhibited nipple abnormality. Incidental tumors were all DCIS, averaged seven ducts, and showed no residual tumor during mastectomy. Mammographic lesions averaged 117 ducts (31% (eight of 26) were DCISM and 42% (11 of 26) were multicentric). Most comedocarcinomas that showed a high incidence of microinvasion were in this group. Clinical lesions averaged 110 ducts (42% (eight of 19) were DCISM and 68% (13 of 19) were multicentric). Three had nodal metastases. Mammographic and clinical tumors in the quantitative range of the incidental group (50 ducts) showed significant differences from it for all variables studied. Histologic and quantitative study of these tumors is necessary to best guide treatment. Incidental tumors, however, may only need observation.
TL;DR: The clinical and pathologic data suggest that the MPIC is a nonneoplastic reactive mesothelial proliferation, occasionally simulating a malignant mesothelioma.
Abstract: Twenty-five cases of multilocular peritoneal inclusion cysts (MPIC) were investigated. All but four cases were associated with a history of a previous abdominal or pelvic operation, or evidence of endometriosis or pelvic inflammatory disease, or combinations of these findings. All of the lesions were attached to pelvic organs, 44% also occupied the upper abdominal cavity, and 16% involved the retroperitoneum. In three cases free-floating cysts were present as well. The median diameter of the lesions was 13 cm. The cyst locules were lined by one to several layers of flat to cuboidal mesothelial cells that occasionally formed papillae, had a hobnail shape, or had undergone squamous metaplasia. The stroma was characterized by chronic inflammation and often acute inflammation. In most of the cases there was mural proliferation of the mesothelial cells, occasionally simulating a malignant mesothelioma. Twelve lesions were complicated by postoperative local recurrence; in four of these cases the recurrences were multiple; neither the size of the lesion nor the presence of mural mesothelial proliferation influenced the outcome. The clinical and pathologic data in this series suggest that the MPIC is a nonneoplastic reactive mesothelial proliferation.
TL;DR: The degree of budding, which was abundant in the actively in asive region, showed a strong correlation with the degree of ly and the existence of n in the resected specimens, implying that the level of budding in theactively invasive region can be a great help in predicting the presence of n.
Abstract: We examined resected specimens from 40 cases of advanced rectal cancer to determine the extent of microtubular cancer nests and undifferentiated cancer cells (budding). We investigated the relationship between this budding and lymphatic invasion (ly), venous invasion (v), and lymph node metastasis (n), respectively. Moreover, we examined the relationship between ly, budding, and n in the preoperative biopsy specimens of 112 patients, including those of the 40 cases mentioned above. The degree of budding, which was abundant in the actively invasive region, showed a strong correlation with the degree of ly and the existence of n in the resected specimens. Also, budding was recognized in a relatively large portion of the biopsy specimens (52 of 112 [46.4%]) and lymph node metastasis was found in 41 of 52 specimens (78.8%). In 57 specimens, neither ly nor budding was found, and 16 of these specimens (28.1%) had positive lymph nodes. These results implied that the degree of budding in the actively invasive region can be a great help in predicting the presence of n. The presence or absence of budding in preoperative biopsy specimens also can be an important factor (along with the degree of differentiation and ly) in estimating the probability of n.
TL;DR: The current knowledge about the epidemiology of cancer pain and its syndromes is summarized.
Abstract: Medical practitioners face the challenge of assuring that pain management has a central place in the treatment of patients with cancer. To meet this challenge, they must understand the prevalence of pain in cancer patients, the frequency with which cancer pain goes untreated or is inadequately managed, and the numerous causes and manifestations of cancer pain. With the goal of contributing to this understanding, this article summarizes the current knowledge about the epidemiology of cancer pain and its syndromes.
TL;DR: In general, nephrectomy alone appears to be adequate therapy for CPDN, but regular monitoring by noninvasive techniques would seem advisable, and the authors recommend several modifications of existing terminology and definitional criteria for these lesions.
Abstract: The entities commonly known as multi-locular cyst of the kidney (MLC) and cystic partially differentiated nephroblastoma (CPDN) were reviewed, based on material in the National Wilms' Tumor Study Pathology Center. The authors recommend several modifications of existing terminology and definitional criteria for these lesions. Because MLC probably represents a neoplastic lesion, the designation "cystic nephroma" (CN) is preferred. This term should be used only for predominantly cystic tumors composed entirely of differentiated tissues, without blastema or other embryonal elements. The designation CPDN should be applied to predominantly cystic lesions, lacking nodular solid regions, in which blastemal or other embryonal cells are present in the septa of the cysts. Solid Wilms' tumor with multifocal cystic change should be distinguished from CPDN. Five cases of CN and 18 cases of CPDN were reviewed. No CN, for which follow-up data was available, showed aggressive behavior. Only one case of CPDN underwent local recurrence, and there were no metastases. In general, nephrectomy alone appears to be adequate therapy for CPDN, but regular monitoring by noninvasive techniques would seem advisable.
TL;DR: Assessment of the validity and reliability of a tool designed to evaluate quality of life as a measure of pain management outcome in the individual patient revealed that it has test‐retest reliability, internal consistency, and interrater reliability, as well as content and construct validity for the major factors, psychologic well‐being, worry, and nutrition.
Abstract: Valid measurement tools are needed by oncology researchers to help in the evaluation of the effectiveness of pain relief methods used in the treatment of cancer patients. A study was conducted to assess the validity and reliability of a tool designed to evaluate quality of life as a measure of pain management outcome in the individual patient. Items in the tested quality of life survey represented the areas of psychologic well-being, physical well-being, general and specific symptom control, and degree of social support. Using the test instrument, two oncology nurses interviewed subjects in three groups, each consisting of 50 subjects: cancer patients with pain, cancer patients without pain, and subjects with no cancer. Statistical analysis of the interview results revealed that the instrument has test-retest reliability, internal consistency, and interrater reliability, as well as content and construct validity for the major factors, psychologic well-being, worry, and nutrition. Further revision of the instrument is needed to restructure its subscales. The quality of life tool will enable researchers to evaluate a treatment regarding not only its effect on pain intensity but also its impact on the total individual.
TL;DR: Women's sexual satisfaction, capacity for orgasm, and frequency of masturbation remained stable, whereas frequency of sexual activity with a partner and range of sexual practices decreased significantly by one year; cancer treatment modality was not related to marital happiness or stability, however.
Abstract: Assessment of sexual frequency, function, and behavior, as well as marital happiness and psychological distress was performed for 61 women with early stage, invasive cervical cancer at the time of diagnosis. Cancer treatment was radical hysterectomy alone for 26 women and radiotherapy with or without surgery for 37. Followups took place at 6 and 12 months after cancer therapy. Women's sexual satisfaction, capacity for orgasm, and frequency of masturbation remained stable, whereas frequency of sexual activity with a partner and range of sexual practices decreased significantly by one year. Women who received irradiation with or without surgery resembled women who underwent radical hysterectomy alone at 6 months. By one year, however, the radiotherapy group had developed dyspareunia, which was reflected in gynecologist ratings at pelvic examination. The women receiving radiotherapy also had more problems with sexual desire and arousal, and were less likely to resume several daily life activities. Cancer treatment modality was not related to marital happiness or stability, however.
