Health-related Quality of Life Measured by the EORTC QLQ-C30 Reference Values From a Large Sample of the Swedish Population

Abstract: The EORTC QLQ-C30 Health-Related Quality of Life (HRQOL) questionnaire was completed by 3069/3919 (78%) of a random sample of the Swedish population aged 18-79 years. The aims of the study were to provide normative data on the questionnaire and to investigate differences in HRQOL with respect to age, gender, sociodemographic characteristics and reported chronic health problems. Women had lower scores than men on all but one of the EORTC QLQ-C30 subscales and reported more chronic health problems. The oldest respondents (70-79 years) had a greater degree of impaired HRQOL than the other age groups, with one exception, 'Emotional functioning', in which they scored higher. Unemployed respondents reported poorer HRQOL than employed respondents. Higher income was associated with a more positive assessment of HRQOL. The results of the study present reference values for EORTC QLQ-C30 Version 3 questionnaire and clarify the influence of factors which should be taken into account when planning studies of HRQOL.

Treatment of breast-cancer-related lymphedema with or without manual lymphatic drainage--a randomized study.

Abstract: A prospective randomized study was carried out to investigate whether the addition of manual lymphatic drainage (MLD) to the standard therapy could improve treatment outcome in women with lymphedema of the ipsilateral arm after breast cancer treatment. Forty-two patients were randomly assigned to receive standard therapy or standard therapy plus MLD 8 times in 2 weeks and training in self-massage. The standard therapy consisted of use of a compression garment, exercises and information about lymphedema and skin care. The efficacy of treatment was evaluated by reduction in lymphedema volume during treatment and by improvement in symptoms potentially related to lymphedema. The patients were followed-up for a total of 12 months. The study showed that both groups obtained a significant reduction in edema and that MLD did not contribute significantly to reduce edema volume.

Gynaecological infections as risk determinants of subsequent cervical neoplasia.

Abstract: A longitudinal cohort study was carried out to determine whether gynaecological infections other than human papillomavirus (HPV) are also related to the subsequent increased risk of cervical neoplasia. The study comprised 19114 women attending the organized mass screening in Finland in 1985-1990 with cytologically detected HPV, Actinomyces, herpes simplex, Trichomonas vaginalis, or yeast. The women were followed-up for subsequent preinvasive lesions and invasive cancers until the end of 1994 by linkage to the nation-wide Cancer Registry. Standardized incidence ratios (SIR) with rates for the whole of Finland as reference and 95% confidence intervals (CI) were estimated. Trichomonas vaginalis and HPV were associated with a high relative risk of cervical cancer, SIR 6.4 (CI 3.7-10, preinvasive lesion and invasive cancer combined) and SIR 5.5 (CI 4.2 7.2, preinvasive lesion and invasive cancer combined), respectively. Herpes simplex was rarely detected, but the highest and statistically most significant point estimate was observed (SIR 12, CI 2.4-34, preinvasive lesion and invasive cancer combined). Neither Actinomyces nor yeast was associated with a significantly increased risk of cervical cancer. None of these results could be accounted for by the confounding effect of the other infections. Our results, based on a prospective design, lead us to propose that Trichomonas vaginalis and herpes simplex virus are also predictors for cervical neoplasia.

Information needs and preferences for participation in treatment decisions among Swedish breast cancer patients.

Abstract: Patient participation in treatment decisions presupposes well-informed patients. The purpose of this study was to determine Swedish breast cancer patients' information needs and their preferences for participation in treatment decisions. Patients (n = 201) were interviewed on nine categories of information and five patient roles, using paired comparisons. Patients gave priority to facts about disease and treatment (chances of cure, stage of disease, treatment options). A collaborative role in treatment decisions was preferred by 87% of the patients. Most patients (56%) preferred a passive form of collaboration: I prefer that my doctor makes the final decision about my treatment but seriously considers my opinion. Younger and better educated patients tended to prefer a more active role. Many patients wanted to be more active (20%) and some more passive (8%) than they actually were. Patients gave priority to disease-specific information, but this reflected needs other than taking control of treatment decisions.

Arm morbidity after breast-conserving therapy for breast cancer.

Abstract: This study reports on 110 consecutive patients, mean age 59 years, operated on for partial mastectomy and axillary dissection. Radiotherapy of 50 Gy was administered to 75 of the patients. Most tumours were T1 tumours and all patients were N0. Lymphoedema is defined as an increase in arm volume >10% and impaired shoulder mobility as an impairment of 15 ° compared with the preoperative value. After operation, 21 patients developed lymphoedema, 17 in the radiotherapy group and 4 in the group without radiotherapy; 49% of the patients had reduced shoulder mobility, and of these, 57% were in the radiotherapy group and 30% in the group without radiotherapy. We found a good correlation between the number of patients stating arm swelling and patients with registered lymphoedema. There were fewer patients stating limitation of movement than patients with registered impaired mobility; 31% of patients were still perceiving some pain five years after the operation. We conclude, that breast-conserving therapy in br...

Late treatment-related morbidity in breast cancer patients randomized to postmastectomy radiotherapy and systemic treatment versus systemic treatment alone.

Abstract: Late treatment-related morbidity after mastectomy and adjuvant systemic treatment with and without postoperative irradiation was assessed in 84 patients randomized in the Danish Breast Cancer Cooperative Group Trials 82b and c A structured interview and physical examination, using a standardized assessment sheet, constructed on the basis of the late effects normal tissues (LENT) scoring system, was used The median length of follow-up from mastectomy was 9 years (range 6-13 years) Lymphedema was measured in 14%, of the irradiated patients versus 3% of the non-irradiated patients (NS) Slightly decreased shoulder morbidity was measured in 45% of the irradiated women versus 15% of the non-irradiated patients, but moderate or more severe impairment was seen in only 5% of the irradiated patients and in none of the non-irradiated patients (p = 0004) Seventeen percent of the irradiated patients and 2% of the non-irradiated patients found that impairment of shoulder movement caused symptoms (p = 0001)

Histologic grading in breast cancer--reproducibility between seven pathologic departments. South Sweden Breast Cancer Group.

Abstract: Histologic grade, including tubular formations, nuclear grade, and mitotic activity, is a well-documented prognostic factor in breast cancer. In comparison with other prognostic parameters, the evaluation of histologic grade is cheap and can be performed, in principle, in all cases of breast cancer. One possible disadvantage is that the evaluation may vary between different pathological departments. The aim of the present work was therefore to study the reproducibility of the histologic grading system by distributing haematoxylin-erythrosin-stained slides from 93 invasive breast cancers to the seven pathology departments within the southern healthcare region of Sweden. The evaluation was performed blindly and without any knowledge of other clinical parameters. In 31% of the cases the same histologic grade was obtained for all departments. The overall mean kappa was 0.54, indicating a moderate reproducibility. Of the three factors included in histologic grade, the agreement was best for tubular formations and poorest for nuclear grade and mitotic activity. The overall moderate reproducibility should be considered when the clinical usefulness of histologic grading is compared with other prognostic instruments.

High intratumoral accumulation of stealth liposomal doxorubicin in sarcomas--rationale for combination with radiotherapy.

Abstract: Sarcomas are radioresistant tumors, the only curative therapy being radical surgical resection. Stealth® liposomal doxorubicin (Caelyx®) is a novel drug formulation that allows prolonged circulation and high intratumoral concentration. This study investigates the concurrent use of radiotherapy with Caelyx® in a cohort of 7 patients with locally advanced or recurrent sarcoma. Radiotherapy was given as a standard fractionation regimen to a total dose of 70 Gy. Caelyx® was given as a 30-min infusion at a dose of 25 mg/m2

Liposuction Gives Complete Reduction of Chronic Large Arm Lymphedema After Breast Cancer

Abstract: About one-third of all women treated for breast cancer develop arm lymphedema. In addition to the worry of the cancer itself, the swollen and heavy arm is both a physical and a psychosocial handicap for the patients. Previous surgical and conservative treatments have not always given satisfactory and permanent results, conceivably because lymphedema causes hypertrophy of the subcutaneous adipose tissue. From this point of view, liposuction (LS) combined with Controlled Compression Therapy (CCT) is an interesting approach, as the hypertrophied adipose tissue is effectively removed and the outcome sustained by wearing a compression garment. Pre- and postoperative arm edema volumes were measured using the water displacement technique. Skin blood flow was recorded using Laser Doppler imaging. Lymph transport in the arm was assessed by indirect lymphoscintigraphy. LS+CCT reduced the arm edema volume completely, compared with a 50% decrease following CCT alone. The use of a compression garment after liposuction...

Risk factors of arm lymphedema in breast cancer patients.

Abstract: Chronic lymphedema is a life-long, potential complication of axillary treatment for breast cancer patients. In this article we focus on risk factors in the development of arm lymphedema and also discuss definition, type and stage, and incidence of arm edema.

Treatment of morbidity associated with the management of the axilla in breast-conserving therapy.

Abstract: The purpose of this study was to determine the impact of surgery and radiotherapy on late morbidity associated with the management of the axilla in breast cancer patients. Two hundred and sixty-six patients from a randomized breast conservation trial (DBCG-82TM protocol) were called in for a single follow-up interview and clinical examination of several functional outcome measures after a median of 6.6 years (3.5-10.5). All the patients were treated with lumpectomy and axillary dissection, followed by external beam radiotherapy to the residual breast. High-risk patients were given additional radiation to the regional lymph nodes plus adjuvant systemic treatment. Twenty-eight patients (11%) had arm edema (> or = 2 cm), which was associated with the extent of axillary node dissection as well as with age and radiotherapy (relative risk, RR = 4.5 (1.8-11.2, p = 0.001)). Impaired shoulder movement of any degree (7%) was associated with radiotherapy (RR = 4.0 (1.5-13.8, p = 0.007)) and advanced age (p = 0.002), while the extent of axillary dissection as described by the number of nodes retrieved was the only factor that predicted pain on logistic regression analysis (p = 0.02). A moderate to severe change in arm/shoulder strength and working ability was observed in 7% and 5% of patients, respectively, but no independent predisposing factor was discerned for these endpoints. It is concluded that the level of late functional morbidity several years after breast-conserving treatment is relatively low and clearly relates to age, extension of surgery, irradiation of the axilla or a combination of these factors, depending on the specific clinical outcome measure.

Morbidity related to axillary irradiation in the treatment of breast cancer.

Abstract: Some of the most debilitating morbidity after surgery and radiotherapy for breast cancer is related to treatment of the axilla. This includes persistent arm lymphoedema, impaired shoulder mobility and brachial plexopathy. Considerable research efforts have been carried out on the radiation pathogenesis and the clinical radiobiology of these clinical endpoints, which has enabled their severity and incidence to be minimized. It is clear that the radiation dose-response relationships for these late endpoints are very steep. In other words, even small changes in the exact dose fractionation and physical dose distribution can cause major changes in toxicity. In particular, in many treatment schedules dose fractions larger than 2 Gy have been used without a sufficient reduction in total dose to avoid increased late effects. This is important, as much of the available literature reports side effects after suboptimal dose-fractionation schedules and inferior radiotherapy techniques. Such reports are not representative of what can be achieved using modern radiotherapy. An interesting parallelism to the problems encountered in reviewing historical experience is found in the British breast litigation, the current status of which is presented in this article. Furthermore, morbidity after radiotherapy is strongly influenced by concomitant surgery and/or chemotherapy, and this should be allowed for when designing the overall treatment. Apart from other therapeutic modalities, it has been suggested that other exogenous factors have an influence on the risk of radiotherapy-related morbidity. However, patients' age and, in the case of lymphoedema, also obesity are the only factors that have been established with some certainty. Routine adjustment of radiotherapy dose in these cases is not recommended. Two current developments may strengthen the role of radiotherapy in the treatment of breast cancer. Sentinel node biopsy may allow nodal staging without major surgical excision of axillary nodes and this opens the possibility for a more optimal combination of radiotherapy and surgery in the management of the axilla. With more cancers now being detected by systematic screening programmes, this will also increase the possibilities for conservative management, which in most cases involves radiotherapy. In conclusion, the improved understanding of the clinical radiobiology of late sequelae after radiotherapy allows treatment schedules and techniques to be devised that are therapeutically effective while maintaining a minimal risk of serious, late morbidity.

Conformal radiotherapy and intensity-modulated radiotherapy--clinical data.

Abstract: Conformal radiotherapy (CRT) is based on three hypotheses: (i) a higher rate of local control can improve the survival rate; (ii) dose escalation can increase tumor control; and (iii) CRT allows the delivery of higher doses by decreasing the incidence of late effects. These postulates are now supported by several data. Three-dimensional conformal radiotherapy (3D-CRT) has markedly progressed since its introduction two decades ago. However, there are situations for which 3D-CRT cannot produce a satisfactory treatment plan because of complex target volume shapes or the close proximity of sensitive normal tissues. This is why intensity-modulated radiation therapy (IMRT) was introduced. Its aim is to overcome the limitations of 3D-CRT by adding modulators of beam intensity to beam shaping. IMRT can achieve nearly any dose distribution; however, the role of the planner remains crucial. CRT has been investigated mainly for prostate cancers and head and neck cancers. By and large, the clinical data, although still limited, seem to confirm the advantages of this type of radiotherapy. Dose escalation in prostate cancers improves the local control rate without increasing late effects and for this cancer site IMRT appears to be a significant advance over conventional 3D-CRT. In head and neck cancers the clinical data are still scarce but encouraging. CRT should be investigated in breast cancers with the aim of reducing the incidence of late effects. The available data underline the great potential for major progress in 3D-CRT and IMRT. The techniques are still costly and time consuming, nevertheless they merit investigation since their cost should decrease. Efforts should be concentrated on the specification of robust optimization criteria, taking into account clinical and radiobiological data.

Development of radiation therapy optimization.

Abstract: The principal radiobiological problems in the treatment of advanced tumors and the solution of many of them by radiobiologically optimized intensity-modulated radiation therapy are presented. Considerable improvements of the treatment outcome using radiobiologically optimized intensity-modulated treatments are achieved by: (a) increasing the tumor dose and dose per fraction; (b) keeping constant or even reducing slightly the dose and dose per fraction to organs at risk; (c) reducing the overall treatment time and the number of treatment fractions. The merits of the new radiation modalities and advanced intensity-modulated treatment techniques are compared in terms of equipment costs per patient cured. It is predicted that the new development of radiobiologically optimized intensity-modulated radiation therapy will rapidly become an important clinical tool, increasing the efficiency of the collaboration between radiation physicists, radiation biologists and radiation oncologists. Not only does it allow the...

Brachial plexopathy after postoperative radiotherapy of breast cancer patients--a long-term follow-up

Abstract: In 1963-1965 a group of 71 patients operated on for breast cancer with total mastectomy and axillary clearance were given aggressive postoperative telecobalt therapy to the axillary, supraclavicular and parasternal lymph node regions. The prescribed dose to these lymph node regions was 44 Gy in 11 fractions. Only two of the three fields were treated per day. Retrospective dose calculations showed that the total dose in the brachial plexus from the axillary and supraclavicular fields was c. 57 Gy in 16-17 fractions over 3-4 weeks. After a few years, symptoms and signs of brachial plexus injury appeared in many patients, which was reported in some early papers. The cohort has now been followed-up to 34 years. As expected, there was progression of both prevalence and severity of the late effects between 5 and 34 years and 11 of 12 patients who are still alive have paralysis of their arms. The neuropathy seems to be closely linked to fibrosis around the nerve trunks. The use of large daily fractions, in some cases combined with hot spots from overlapping fields, was certainly the cause of the complication.

Hypopharyngeal squamous cell carcinoma--treatment results in 138 consecutively admitted patients.

Abstract: The aim of this study was to evaluate the results of the initial and salvage treatment for hypopharyngeal carcinoma. The study was conducted in 1963 to 1991 and included 138 patients (38 females (28%) and 100 males (73%)). Most of the tumours originated in the piriform sinus (86%). Tumour stage distribution was T1: 20%, T2: 27%, T3: 37% and T4: 17% and nodal stage distribution was N0: 45%, N1: 25%, N2: 10%, and N3: 20%. Primary treatment was delivered with curative intent in 124 out of 138 cases (90%). Treatment failure was noted in 98 patients, with 55% recurrence in T-position, 39% in N-position, and 14% at distant metastases sites. Salvage surgery was successful in 9 out of 32 patients. The overall 5-year locoregional tumour control, cause-specific and overall survival rates were 20%, 25% and 19%, respectively. Univariate actuarial analysis showed that T- and N-stage, clinical stage, tumour size and well-differentiated tumours were significant prognostic parameters. A Cox multivariate analysis showed that only the T- and N-stages were independent prognostic factors. In conclusion, the prognosis for advanced hypopharyngeal carcinoma is extremely poor and the meagre results with conventional radiotherapy alone indicate that other treatment modalities should be introduced in the management of this disease.

Patient and staff perceptions of cancer patients' psychological concerns and needs.

Abstract: This paper reviews patient and staff perceptions of cancer patients' psychological concerns and needs. An extensive literature search resulted in a total of 22 studies. Six of these concern staff ratings of hypothetical 'average' patients, and the main findings are that staff and patients are in relative agreement about the overall spectrum of concerns relevant to cancer patients, but less so regarding which concerns are of most importance to patients. Sixteen studies compare patient ratings with staff ratings of individual patients. The overall pattern of results indicates that staff tend to overestimate patient anxiety and emotional distress and show limited ability adequately to assess patient distress in terms of rank. Staff were able correctly to detect a majority of anxiety 'cases', while the identification of depression was less accurate. High detection rates for anxiety were obtained partly at the expense of staff also presuming anxiety in many non-distressed patients. Generally, there was better ...

TP53 mutation is an independent prognostic marker for poor outcome in both node-negative and node-positive breast cancer.

Abstract: TP53 gene-mutation and protein expression of p53 are described as being of prognostic importance for the outcome of breast cancer The present study was therefore carried out to evaluate whether TP53 mutation would be a feasible prognostic marker in the routine diagnostic evaluation of breast cancer, and, in particular, to analyse the relationship between TP53 mutation and nodal status Tumour material was obtained from women with sporadic early breast cancer Gene mutations in exon 2-11 were identified using denaturing gradient gel electrophoresis (DGGE) as the initial scanning procedure and characterized by sequencing All patients were treated according to the guidelines of the Danish Breast Cancer Cooperative Group for the DBCG 89 protocols The results were correlated with clinico-pathological parameters and the prognosis evaluated by uni- and multivariate analysis using local control, freedom from distant metastasis, disease-free survival, and overall survival as endpoints The study included 294 patients TP53 mutations were found in 23% of cases Mutations were significantly more frequent in tumours from patients who were node-positive and with tumours characterized as being ductal, large of size, with a high degree of anaplasia, and oestrogen receptor negative Using univariate analysis, it was found that distant metastasis, disease-free, and overall survival were correlated to tumour size, nodal status, degree of anaplasia, oestrogen receptor status, and TP53 mutation In addition, overall survival was also correlated to age and menopausal status When analysed according to nodal status, TP53 mutation was found to have a significantly poor survival probability in each of the subgroups A Cox proportional hazard analysis, including all 294 patients, demonstrated that positive nodal status and TP53 mutation were the only parameters that had an independent poor influence on the risk of developing distant metastasis and reduced recurrence-free survival The same factors together with postmenopausal status were found to be significantly associated with increased risk of death TP53 mutation is a strong marker for the prediction of overall and disease-free survival in breast cancer, irrespective of nodal status A better understanding of the role of the p53 pathway, including analysis of different types of TP53 mutations, is required in order further to investigate the prognostic potential of this marker

Maspin--a novel protease inhibitor with tumor-suppressing activity in breast cancer.

Abstract: Maspin (mammary serpin) is a novel serine protease inhibitor related to the serpin family with a tumor-suppressing function in breast cancer. Maspin was originally identified from normal mammary epithelium by subtractive hybridization and might function as a class II tumor-suppressor gene. Maspin's decreased expression with increased level of malignancy and its loss in metastatic cells is regulated at the transcriptional level. Cytosin methylation and heterochromatinization in the promoter region might account for this down-regulation of maspin. Transfection of tumor cells with maspin cDNA inhibits invasion and motility and decreases tumor growth and metastatic ability in nude mice. Maspin interacts with the p53 tumor-suppressor pathway and function as an inhibitor of angiogenesis in vitro and in vivo. The progressive loss of expression of maspin during tumor progression makes this new protein an interesting diagnostic and prognostic marker. The re-expression of maspin by pharmacological intervention potentially offers a promising approach as a therapeutic option in breast cancer therapy.

Risk factors for basal cell carcinoma.

Abstract: The aim of this study was to assess the risk factors for basal cell carcinoma (BCC). A case-control study, carried out in two towns in Yugoslavia, comprised 200 BCC cases and 399 controls. For statistical analysis, univariate and multivariate logistic regressions were used. The risk factors found for BCC were: freckling before the age 15, seven or more weeks per year spent at the seaside during holidays (lifetime average), outdoor work during summer-time, occupational exposure to organic and non-organic dissolvents and organophosphatic compounds, use of tar for cosmetic purposes, and previous BCC in personal history. Subjects who tended to burn and not to tan after sun exposure also showed a significantly higher risk for BCC. Brown eyes and history of acne had a protective effect. This study confirmed the role of both constitutional and environmental factors in the development of BCC.

Feasibility of detecting hypoxia in experimental mouse tumours with 18F-fluorinated tracers and positron emission tomography : A study evaluating [18F]Fluoromisonidazole and [18F]fluoro-2-deoxy-D-glucose

Abstract: The study was designed to investigate the binding of [18F]Fluoromisonidazole ([18F]FMISO) and [18F]Fluoro-2-deoxy-D-glucose ([18F]FDG) in a C3H mouse mammary carcinoma. Non-anaesthetized tumour-bearing animals breathing either normal air or carbogen (to reduce tumour hypoxia) were examined by PET after tracer injection. Tumours were identified by radioactive labelling and methods of defining regions of interest (ROI) in the tumours were investigated. Reference tissue was selected elsewhere in the mice and the ratio between mean radioactivity in tumour and reference tissue was compared. The results showed a correlation between the methods of identifying ROIs and a significantly lower tumour to reference tissue ratio for carbogen-treated mice compared with controls when using [18F]FMISO. Only one of the methods showed a significant difference in the tumour labelling between treatment groups using [18F]FDG. The study supports the contention that [18F]FMISO may be able to identify hypoxia in tumours, whereas ...

Results of prophylactic irradiation in patients with resected keloids--a retrospective analysis.

Abstract: The data of 139 patients with 166 keloids treated postoperatively between 1962 and 1996 were evaluated for prognostic factors and outcomes. Treatment commenced within 48 h after surgery. Radiotherapy was carried out as brachytherapy, using an integrated radionuclide 90 Sr-90Y surface applicator. The median dose delivered to the subcutis amounted to 14 Gy (range 7.5-28.5 Gy). The overall recurrence-free response rate was calculated to be 80% for all keloids. Response rates differed significantly (p < 0.001) between the different anatomical regions. The recurrence rate was lowest (2%) with keloids of the face and neck and highest with keloids of the thorax (49%). Outcome also differed significantly, depending on the etiology. Keloids following burns had a poorer success rate than those developing after surgery or mechanical trauma (p < 0.001). We were unable to demonstrate any significance in outcome related to gender, age or size. No direct correlation was found between total doses and response rates. In our patients there were no signs of secondary malignancies in the irradiation area within a median follow-up period of 12 years. Two new prognostic factors have been identified: keloid etiology and localization of the disorder.

Morphine or oxycodone in cancer pain

Abstract: Oxycodone is an opioid analgesic that closely resembles morphine. Oxymorphone, the active metabolite of oxycodone, is formed in a reaction catalyzed by CYP2D6, which is under polymorphic genetic control. The role of oxymorphone in the analgesic effect of oxycodone is not yet clear. In this study, controlled-release (CR) oxycodone and morphine were examined in cancer pain. CR oxycodone and morphine were administered to 45 adult patients with stable pain for 3-6 days after open-label titration in a randomized, double-blind, cross-over trial. Twenty patients were evaluable. Both opioids provided adequate analgesia. The variation in plasma morphine concentrations was higher than that of oxycodone, consistent with the lower bioavailability of morphine. Liver dysfunction affected selectively either oxycodone or morphine metabolism. Three patients with markedly aberrant plasma opioid concentrations are presented. Significant individual variation in morphine and oxycodone metabolism may account for abnormal responses during treatment of chronic cancer pain.

Health-related quality of life and occurrence of intestinal side effects after pelvic radiotherapy--evaluation of long-term effects of diagnosis and treatment.

Abstract: Health-related quality of life (HRQOL) and occurrence of late intestinal side effects were assessed 3-4 years after pelvic radiotherapy for carcinoma of the endometrium and cervix. During 1988-1990, 143 women were included in a clinical trial to evaluate the effect of a low fat, low lactose diet on radiation-induced diarrhoea. Of 94 survivors, 79 (84%) answered the request. HRQOL was assessed by the EORTC QLQ-C36 and compared with population-based norms. The women scored lower than the general population on role functioning (81.5 versus 90.6 (p<0.01)) and higher on diarrhoea (23.8 versus 9.5 (p<0.01)). Compared with pre-treatment conditions, an increase in cases with pain in the lower back, hips and thighs was seen. Substantial pain and diarrhoea were associated with deterioration in HRQOL. In conclusion, few treatment and/or disease-related effects were detected 3-4 years after radiotherapy, with the exception of increased bowel frequency and pain in the lower back, hips and thighs.

Urinary Excretion of Platinum in Chemotherapy-treated Long-term Survivors of Testicular Cancer

Abstract: As the majority of patients with metastatic testicular cancer are cured by cisplatin-based chemotherapy and can expect an additional life span of around 50 years, late toxicity is of particular relevance. Urine and serum concentrations of platinum were determined by voltammetry in 37 patients at 5.3 to 16.8 years after cisplatin-based chemotherapy. Urinary excretion and serum levels of platinum were 100 to 1000 times higher in patients than in unexposed controls. There may be an association between platinum storage and endocrinologic and metabolic late sequelae, as well as a risk of second cancer. However, further research is necessary to clarify the biological relevance of long-term storage of platinum.

Imaging of axillary lymph nodes.

Abstract: There is increasing interest in the radiological diagnosis of axillary lymph nodes in patients with breast cancer, especially in the preoperative diagnosis of metastatic nodes. Both CT (computed tomography) and MRI (magnetic resonance imaging) are cross-sectional imaging methods that produce high-quality images of the axilla. MRI also uses contrast enhancement profile, for example in imaging of breast lesions. Few studies have been published on this subject, but the latest have shown high sensitivity and specificity (CT 93.8 and 82.1%, respectively; MRI 90 and 82%, respectively), although, both CT and MRI are restricted to imaging only. US (ultrasound) is widely spread and is fast and accurate with high resolution. Sensitivity and specificity vary (68.2-92% and 90-100%, respectively). Most importantly, there is the possibility of US-guided FNAB (fine-needle aspiration biopsy) of pathological nodes, which increases the specificity. Initial results with colour Doppler are promising, but a recent study has shown that the presence of colour Doppler flow signal is highly non-specific. Other parameters such as flow pattern and distribution may prove to be of value in this method. Today, the method of choice for the daily routine is US in conjunction with FNAB.

Esthesioneuroblastoma: What is the Optimal Treatment?

Abstract: A retrospective review was conducted on 13 patients with esthesioneuroblastoma (ENB), treated at our institution from 1977 to 1997. According to the Kadish classification, one patient was in stage A, 5 patients were classified as stage B and 7 patients were in stage C. Five-year disease-specific survival was found to be 51%. Forty-six percent of the patients experienced relapse and despite intensive salvage therapy, median survival after recurrences was only 12 months. This indicates the need for good primary control in local as well as distant disease. The role of pre- versus postoperative radiotherapy to secure good local control is discussed and compared with the literature, and treatment guidelines are proposed. The tumours were graded according to the Hyams' classification and its importance as a prognostic factor is briefly discussed.

Imaging of Myeloma Bone Disease - Implications for Staging, Prognosis and Follow-up

Abstract: Among all imaging modalities, magnetic resonance imaging provides the most useful information about the accurate staging of solitary bone plasmacytoma, the prediction of progression of asymptomatic multiple myeloma and the prognosis of symptomatic multiple myeloma. Furthermore, magnetic resonance imaging contributes to the differential diagnosis of compression fractures in patients with myeloma and can be used for assessment of response to treatment.

Neoadjuvant Chemotherapy for Ewing's Sarcoma of Bone in Patients Older than Thirty-nine Years: Experience of Twenty-three Cases at the Istituto Ortopedico Rizzoli

Abstract: The aim of this study was to determine whether the behaviour of Ewing's sarcoma of bone in adult patients is the same as that observed in children and adolescents. We reviewed the clinical features and outcomes of 23 patients over the age of 39 (17 males, 6 females) who had been treated with neoadjuvant chemotherapy between 1983 and 1995 at our institution. The most common primary sites of tumor were the extremities (16 cases); tumor volume was more than 100 ml in 17 patients, and elevated serum LDH levels were found in 6 cases. The local treatment was surgery in 8 cases, surgery plus radiotherapy in 8, and radiotherapy alone in 7 cases. Chemotherapy comprised a 4-drug regimen in 10 patients, while the other 13 patients received 6 drugs. At a follow-up of 8.8 years (3.5-15) 13 patients remained continuously free of disease and 10 relapsed. The 5-year disease-free survival and overall survival rates were 53% and 59%, respectively. Clinical features, dose intensity, and toxicity of chemotherapy, as well as ...

Diagnostic delay in pediatric malignancies--a population-based study.
