RESUMEN

BACKGROUND: Late recurrences in postmenopausal women with hormone receptor-positive breast cancers remain an important challenge. Avoidance or delayed development of resistance represents the main objective in extended endocrine therapy (ET). In animal models, resistance was reversed with restoration of circulating estrogen levels during interruption of letrozole treatment. This phase III, randomized, open-label Study of Letrozole Extension (SOLE) studied the effect of extended intermittent letrozole treatment in comparison with continuous letrozole. In parallel, the SOLE estrogen substudy (SOLE-EST) analyzed the levels of estrogen during the interruption of treatment. PATIENTS AND METHODS: SOLE enrolled 4884 postmenopausal women with hormone receptor-positive, lymph node-positive, operable breast cancer between December 2007 and October 2012 and among them, 104 patients were enrolled in SOLE-EST. They must have undergone local treatment and have completed 4-6 years of adjuvant ET. Patients were randomized between continuous letrozole (2.5 mg/day orally for 5 years) and intermittent letrozole treatment (2.5 mg/day for 9 months followed by a 3-month interruption in years 1-4 and then 2.5 mg/day during all of year 5). RESULTS: Intention-to-treat population included 4851 women in SOLE (n = 2425 in the intermittent and n = 2426 in the continuous letrozole groups) and 103 women in SOLE-EST (n = 78 in the intermittent and n = 25 in the continuous letrozole groups). After a median follow-up of 84 months, 7-year disease-free survival (DFS) was 81.4% in the intermittent group and 81.5% in the continuous group (hazard ratio: 1.03, 95% confidence interval: 0.91-1.17). Reported adverse events were similar in both groups. Circulating estrogen recovery was demonstrated within 6 weeks after the stop of letrozole treatment. CONCLUSIONS: Extended adjuvant ET by intermittent administration of letrozole did not improve DFS compared with continuous use, despite the recovery of circulating estrogen levels. The similar DFS coupled with previously reported quality-of-life advantages suggest intermittent extended treatment is a valid option for patients who require or prefer a treatment interruption.

RESUMEN

The present study analyses the influence of high-dose chemotherapy (HD) and autologous stem cell transplantation on natural and vaccine-induced specific immunity in breast cancer patients. Peripheral blood was collected from five breast cancer patients at serial time points in connection with treatment and in a follow-up period of 1 year. The frequencies of CD8+ and CD4+ T cells responsive to cytomegalovirus (CMV), varicella zoster virus (VZV), and tetanus in antigen-activated whole blood were determined by flow cytometric analysis of CD69, TNF alpha, IFN gamma and IL-4 expression. Mononuclear cells were labelled with PKH26 dye and the CMV, VZV, and tetanus toxoid-specific proliferation of T cell subpopulations was analysed by flow cytometry. In none of the patients did the treatment result in loss of overall T cell reactivity for any of the antigens. Prior to chemotherapy 5/5 patients possessed TNF alpha expressing T cells specific for CMV, 4/5 for VZV, and 3/5 for tetanus. One year after stem cell transplantation all patients possessed TNF alpha expressing T cells specific for CMV, VZV and tetanus. The highest percentages of cytokine-responding T cells were seen after stimulation with CMV antigen. In general, the lowest reactivity (close to zero) was measured in G-CSF-mobilised blood at the time of leukapheresis. In spite of a continuously reduced CD4 to CD8 ratio after transplantation, recovery of CD4+ T cells usually occurred prior to CD8+ recovery and often to a higher level. The study demonstrates that natural as well as vaccine-induced specific immunity established prior to HD can be regained after stem cell transplantation. These data indicate that introduction of a preventive cancer vaccination in combination with intensive chemotherapy may be a realistic treatment option.

RESUMEN

OBJECTIVE: This study was designed to establish prognostic factors for survival of patients with locally advanced or metastatic urothelial cancer. We have furthermore investigated changes in patient characteristics and treatment strategies during the last 20 years. PATIENTS AND METHODS: Between 1992 and 1997, a total of 156 patients with newly diagnosed recurrent locally advanced disease (nonresectable, radioresistant) and/or metastatic transitional cell carcinoma of the urothelial tract were included in a protocol evaluating clinical and laboratory prognostic factors at baseline. The relationship between these characteristics and survival was analyzed using univariate and multivariate methods. The results were compared to the survival results of similar patients treated previously from 1976 to 1991. RESULTS: Median survival after diagnosis of recurrent locally advanced or metastatic disease was 5.8 months. Multivariate analysis showed that good performance status (PS), normal alkaline phosphatase (AP), absence of liver metastases and chemotherapy were independent prognostic factors for long survival. An increase in survival was found when comparison was made with 240 patients treated in the period from 1976 to 1991, but the period of treatment had no independent importance in multivariate analysis. CONCLUSION: PS, AP and liver metastases are the major important prognostic factors in metastatic urothelial cancer. Stage migration and increased use of chemotherapy may have contributed to improved median survival during the last 20 years.

RESUMEN

CAELYX/DOXIL, pegylated liposomal doxorubicin, has shown antitumour activity and reduced toxicity compared with standard doxorubicin in other tumour types. In this prospective randomised trial, 94 eligible patients with advanced soft-tissue sarcoma (STS) were treated, 50 with CAELYX (50 mg/m(2) by a 1 h intravenous (i.v.) infusion every 4 weeks) and 44 with doxorubicin (75 mg/m(2) by an i.v. bolus every 3 weeks). Histological subtypes were evenly matched, 33% were leiomyosarcoma (CAELYX: 18; doxorubicin: 13). Primary disease sites were well matched. CAELYX was significantly less myelosuppressive, only 3 (6%) patients had grade 3 and 4 neutropenia, versus 33 (77%) on doxorubicin; febrile neutropenia occurred in 7 (16%) patients given doxorubicin, but only 1 (2%) given CAELYX. 37 (86%) patients on doxorubicin had grade 2-3 alopecia, but only 3 (6%) on CAELYX, and the major toxicity with CAELYX was to the skin. Palmar-plantar erythrodysesthesia with CAELYX was grade 1: 4 (8%) patients, grade 2: 11 (22%) patients, grade 3: 9 (18%) patients and grade 4: 1 (2%) patient. Other non-haematological grade 3 and 4 toxicities were rare. Confirmed responses were observed with both agents: CAELYX: complete response (CR) 1 (uterine), partial response (PR) 4 (response rate (RR) 10%); and doxorubicin: CR 1, PR 3 (RR of 9%); with the best response being stable disease (NC) in 16 and 18 patients, respectively. The reason for the low response rate is unknown, but it may be due partly to a high proportion of gastrointestinal stromal tumours. In conclusion, CAELYX has equivalent activity to doxorubicin in STS with an improved toxicity profile and should be considered for further investigation in combination with other agents such as ifosfamide.

RESUMEN

PURPOSE: To identify pretreatment variables predicting overall and complete response to cisplatin-based chemotherapy for metastatic urothelial cancer, and to study the relation between response and the duration of survival. PATIENTS AND METHODS: A total of 119 evaluable patients with recurrent locally advanced or metastatic urothelial cancer received cisplatin-based combination chemotherapy in four consecutive phase II studies from 1987 to 1997. The relationship of pretreatment variables and response was evaluated with logistic regression, and prognostic factors for survival were analyzed with Cox's multivariate model. RESULTS: Response was achieved in 49% of the patients with a complete response rate of 15%. Good performance status and absence of bone metastases were independently predictive of overall response. Good performance status and normal hemoglobin were independently predictive of complete response. Median survival was 8.9 months. Performance status, alkaline phosphatase, s-creatinine, liver and bone metastases were independent prognostic factors for survival. Median survival was 12.4 months in responding patients and 6.3 in nonresponding patients. Response to chemotherapy was included in the multivariate model and was the strongest prognostic factor for survival. CONCLUSION: The presence of bone metastases, low hemoglobin or poor performance status predicts decreased chance of response to chemotherapy. Response to chemotherapy is an independent prognostic factor for prolonged survival in patients with metastatic urothelial cancer.

RESUMEN

The efficacy of combined endocrine therapy with tamoxifen (TAM), aminoglutethimide (AG), and hydrocortisone (H) or tamoxifen and fluoxymesterone (FLU) was evaluated against treatment with tamoxifen alone in 311 patients above 65 years of age with a first recurrence of a metastatic breast cancer. A total of 279 patients were eligible. The response rates were assessed for 258 fully evaluable patients and were the following for the TAM (N = 94), the TAM+AG+H (N = 83), and the TAM+FLU (N = 81) groups, respectively, PR: 14, 18, and 21%, and CR: 20, 11, and 23%. The overall response rates are not statistically different (p = 0.30). The 95% CL of difference in response rates for TAM vs. TAM+AG+H are -9-19% and for TAM vs. TAM+FLU -4-25%. Time to treatment failure was comparable with median values of 9.2, 7.7, and 9.2 months in the TAM, TAM+AG+H, and TAM + FLU group, respectively (p = 0.17). The corresponding figures for survival are median times of 22.0, 24.1, and 21.1 months with a p-value of 0.62. Toxicity was more pronounced in both the combined treatment groups, and could in most instances be attributed to treatment with either AG+H or FLU. Currently, new specific aromatase inhibitors with lesser toxicity than AG are being evaluated in combination with TAM for treatment of primary and metastatic breast cancer. In conclusion, the simultaneous use of TAM and AG +H or FLU does not seem to improve the therapeutic efficacy in elderly postmenopausal patients with metastatic disease. So far, combined endocrine therapy in this group of patients should only be used in the context of clinical trials.

RESUMEN

Studies of urothelial tumors have identified structural abnormalities in a number of chromosomes. This study aimed to identify specific genetic changes of patients with advanced urothelial cancers, and relate these changes to increased chemotherapy sensitivity or good prognosis. We screened 56 muscle-invasive bladder cancer tumors for loss of heterozygosity (LOH) at chromosome 1p, 8p, 10p, 13q, and 17p with PCR using 6 microsatellite markers. All patients had recurrent locally advanced or metastatic disease. DNA was extracted after microdissection of the primary tumor and normal tissue from paraffin-embedded specimens. The PCR products were electrophoresed in an ABI Prism 377 DNA sequencer and the alleles from tumor DNA and normal tissue DNA were analyzed using the GeneScan program. The LOH findings were correlated with response to chemotherapy and survival. Allelic loss of specific markers was present in 26-50% of the informative tumors. The most frequent LOH was observed at 17p, supporting the notion that this region may contain genes of importance to urothelial cancer progression. The overall rate of response to chemotherapy was 48%, and ranged from 40% to 56% according to specific LOH changes. The median survival of all patients from start of chemotherapy was 5.8 months and ranged from 5.3 to 7.9 months for patients with specific LOH changes. Response and survival of patients with no lost markers was the same size, compared to patients with one, two, or more lost markers. Specific genetic changes were detected in a significant number of tumors from patients with advanced urothelial cancer. These changes were not predictive of response to chemotherapy or of the duration of survival.

RESUMEN

This study describes self-reported functional and psychological status of patients using The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (QLQ-C30) and relates this to the prognosis. Patients with incurable locally advanced or metastatic transitional cell cancer of the urothelial tract were prospectively included in a study of self-reported functional and psychosocial status. The study included 25 patients; 19 patients completed one or more Quality of Life Questionnaires. The median survival was 5.2 months, and there was a significant relation between functional, emotional, and social status and survival. The self-assessment of functional status was a better prognostic factor for survival than performance status evaluated by the clinician. The value of the global quality of life scale did not relate to survival after recurrence. Functional, emotional, and quality of life scales declined during the progression of the disease. The study suggests that evaluation with self-reporting questionnaires may provide the physician with useful information, and it may aid in making treatment decisions in patients with metastatic bladder cancer.

RESUMEN

This study analyzed prognostic factors at primary diagnosis and at first recurrence for impact on survival after isolated locoregional failure. The aims were: (1) assessment of prognostic factors for time to second locoregional failure, distant failure, and survival in isolated locoregional recurrence of breast cancer after mastectomy; and (2) investigation of the impact of a second locoregional failure on dissemination and survival. Between 1983 and 1985, 99 patients who had undergone mastectomy and then developed isolated local and/or regional recurrences, were treated with radical excision and radiotherapy; none of these patients had distant metastases. Survival and the times to second local failure and distant metastasis were analyzed according to potential prognostic factors. The median follow-up was 123 months; 38 patients were still alive. Median survival was 89 months and the 10-year survival rate was 38%, with no difference between local and regional recurrences. A total of 43 patients developed a second locoregional recurrence after a median of 73 months; primary tumour size and initial node status were significant independent prognostic factors. The annual hazard rates for recurrence were similar for patients developing local failure or systemic recurrence. The 10-year rate of dissemination was 49% for patients with locoregional control, compared with 51% for patients who had a second locoregional recurrence. The prognostic factors for survival were node status at mastectomy and haemoglobin level at first recurrence. The development of a second locoregional recurrence was not associated with an increased risk of dissemination or reduced survival. Differences in prognostic factors for locoregional control and distant metastases suggest that these recurrences represent different biological entities that require different treatment strategies. However, as the achievement of locoregional control had no influence on prognosis, the use of systemic adjuvant therapy may be warranted in a subset of these patients.

RESUMEN

The rate of reduction in the concentration of serum human chorionic gonadotrophin (hCG) following chemotherapy for germ cell tumours may follow a complex pattern, with longer apparent half-life during later stages of chemotherapy, even in patients treated successfully. The commonly used half-life of less than 3 days for hCG to monitor the effect of chemotherapy in patients with germ cell tumours of the testis may represent too simple a model. 125I-labelled hCG was injected intravenously in 27 patients with germ cell tumours and elevated hCG during chemotherapy. The plasma radioactivity and hCG concentrations were followed. During chemotherapy, the plasma disappearance of hCG showed a biphasic pattern, with an initial fast and a later slow component in all patients. Using the steep part of the hCG plasma disappearance curve, five patients who achieved long-term remission had half-lives longer than 3 days (3.6-6.8 days), whereas four out of five patients not achieving long-term remission had half-lives shorter than 3 days. After the third treatment cycle, eight patients who achieved long-term remission had hCG half-lives longer than 3 days (7.4-17.0 days). In these patients, the plasma disappearance of [125I]hCG was equivalent to that of hCG. Thus, the slow decline of hCG represented a slow plasma disappearance rather than a hCG production from vital tumour cells and could, consequently, not be used to select patients for additional or intensified chemotherapy. The concept of a fixed half-life for plasma hCG during treatment of hCG-producing germ cell tumours is inappropriate and should be revised. Difficulties in interpreting a slow decline of hCG may be overcome by comparing the plasma disappearance of total hCG with the plasma disappearance of [125I]hCG.

RESUMEN

PURPOSE: We propose an appropriate assessment of patients with disseminated transitional cell carcinoma of the urothelial tract, and investigate the pattern of metastases relative to pathological features and primary tumor treatment. MATERIALS AND METHODS: A total of 156 consecutive patients with recurrent locally advanced (nonresectable, radioresistant) and/or metastatic transitional cell carcinoma of the urothelial tract were evaluated with blood tests, chest x-ray, bone scintigraphy, bone marrow biopsy, and abdominal and brain computerized tomography. RESULTS: Distant metastases were evident in 86% of the patients, with lymph nodes and bones being the most frequent sites. Bone metastases were mostly in the pelvis or lower spine and were asymptomatic in 19% of patients. Bone marrow metastases were noted in 14% of these patients. However, most of them also had radiological bone metastases and bone marrow biopsy is not recommended for routine evaluation. Approximately 2% of patients had brain metastases without symptoms at recurrence. Elevated lactate dehydrogenase was predictive of disseminated disease. Patients receiving radical radiotherapy as primary treatment had an increased rate of recurrent locally advanced disease but the same frequency of distant metastases compared to those undergoing cystectomy. Primary tumor features did not relate to the pattern of metastases. CONCLUSIONS: We recommend chest x-ray, whole abdominal computerized tomography and routine blood tests, including lactate dehydrogenase, for patients with recurrent locally advanced or metastatic disease. Skeletal symptoms should be examined radiologically, while asymptomatic patients with recurrence in sites other than bone should be evaluated with bone scintigraphy.

RESUMEN

BACKGROUND: Postmastectomy radiotherapy is associated with a lower locoregional recurrence rate and improved disease-free and overall survival when combined with chemotherapy in premenopausal high-risk breast-cancer patients. However, whether the same benefits apply also in postmenopausal women treated with adjuvant tamoxifen for similar high-risk cancer is unclear. In a randomised trial among postmenopausal women who had undergone mastectomy, we compared adjuvant tamoxifen alone with tamoxifen plus postoperative radiotherapy. METHODS: Between 1982 and 1990, postmenopausal women with high-risk breast cancer (stage II or III) were randomly assigned adjuvant tamoxifen (30 mg daily for 1 year) alone (689) or with postoperative radiotherapy to the chest wall and regional lymph nodes (686). Median follow-up was 123 months. The endpoints were first site of recurrence (locoregional recurrence, distant metastases, or both), and disease-free and overall survival. FINDINGS: Locoregional recurrence occurred in 52 (8%) of the radiotherapy plus tamoxifen group and 242 (35%) of the tamoxifen only group (p<0.001). In total there were 321 (47%) and 411 (60%) recurrences, respectively. Disease-free survival was 36% in the radiotherapy plus tamoxifen group and 24% in the tamoxifen alone group (p<0.001). Overall survival was also higher in the radiotherapy group (385 vs 434 deaths; survival 45 vs 36% at 10 years, p=0.03). INTERPRETATION: Postoperative radiotherapy decreased the risk of locoregional recurrence and was associated with improved survival in high-risk postmenopausal breast-cancer patients after mastectomy and limited axillary dissection, with 1 year of adjuvant tamoxifen treatment. Improved survival in high-risk breast cancer can best be achieved by a strategy of both locoregional and systemic tumour control.

RESUMEN

Following modified radical mastectomy, pre- and perimenopausal (amenorrhoea for < 5 years) patients with stage II or III breast cancer received CMF (cyclophosphamide 600, methotrexate 40, 5-fluorouracil 600 mg/m2 intravenously (i.v.) every 4 weeks, 9 cycles). The effect on recurrence-free survival (RFS) and overall survival (OS) of the addition of adjuvant tamoxifen (TAM) to adjuvant chemotherapy was examined by randomisation either to no additional treatment (n = 314), or concurrently TAM 30 mg daily for 1 year (n = 320). 40% had positive, 12% negative and 48% unknown receptor status. One year after surgery 21% versus 35% (CMF + TAM versus CMF) were still menstruating (P < 0.01). With a median follow-up of 12.2 years there was no difference in RFS (10-year RFS 34% versus 35%, P = 0.81) or OS (45% versus 46%, P = 0.73). In a Cox proportional hazards model, tumour size, number of metastatic lymph nodes, frequency of metastatic nodes in relation to total number of nodes removed, degree of anaplasia, age, and menostasia within the first year after operation were significant independent prognostic factors for RFS, and the same factors except age for OS. No significant interactions with TAM were seen. Thus, in this group of pre- and perimenopausal high-risk early breast cancer patients with heterogeneous receptor status given CMF i.v., concurrent TAM for 1 year did not improve the outcome. These results do not exclude that receptor positive patients may benefit from adjuvant TAM for longer periods given sequentially to chemotherapy.

RESUMEN

PURPOSE: Docetaxel and cisplatin has documented single-agent activity and different toxicity profiles in patients with metastatic urothelial cancer. We performed a phase II study in which docetaxel was combined with cisplatin to evaluate response rate, toxicity, and survival. PATIENTS AND METHODS: Eligibility criteria included performance status (World Health Organization [WHO]) less than 3; normal bone marrow, liver, and renal function; and no concurrent malignancy or symptomatic peripheral neuropathy. Docetaxel (Taxotere; Rhône-Poulenc Rorer, Paris, France) 75 mg/m2 was combined with cisplatin 75 mg/m2 every third week. Patients received premedication with prednisolone and clemastine. RESULTS: A total of 25 patients were assessable for response and toxicity. Median age was 64 years; five patients had locoregional disease only and 20 had metastatic disease. Response was achieved in 15 patients (60%; 95% confidence interval [CI], 39% to 79%), including seven patients (26%) who achieved a complete response. Overall median survival time was 13.6 months (range, 1.5 to 26.4+). The most frequent toxicity was nausea and vomiting (80% of patients). Neutropenia grade 3 or 4 was observed in 56% of patients, but only one had febrile neutropenia. Mucositis and diarrhea were encountered in 13% of cycles, mostly grade 1 or 2. Peripheral neuropathy and skin changes grade 1 and 2 were observed in 76% and 36%, respectively. Fluid retention and hypersensitivity reactions were infrequent and mild. CONCLUSION: The combination of docetaxel and cisplatin is effective and feasible in patients with metastatic urothelial cancer with a manageable safety profile.

RESUMEN

OBJECTIVE: To evaluate the effect of oral treosulfan in patients with platinum-resistant ovarian cancer. METHODS: A phase II trial of oral treosulfan 500 mg per day in 30 females with platinum resistant ovarian cancer. All patients had measurable or evaluable disease. RESULTS: The treatment was well tolerated. One patient (3%) achieved a partial response lasting 12+ months. Seven patients had stable disease for 5.3 months (median) range 4.4-7.5 months. Median time to progression was 11.5 weeks (95% C.L. 11-12 weeks). Median survival was 31 weeks (95% C.L. 30-35 weeks). CONCLUSION: Oral treosulfan in the present schedule is not recommended in platinum resistant ovarian cancer.

RESUMEN

PURPOSES: The study evaluated prognostic factors for dissemination and survival in patients with local or regional recurrence of breast cancer. Furthermore, the aim was to define subgroups of patients at different risk of developing metastases in specific anatomical sites. PATIENTS AND METHODS: The study included 140 patients with isolated local or regional node recurrence, who entered a prospective study for staging of patients with first recurrence of breast cancer in the period 1983-85. The primary treatment was a simple mastectomy; node positive patients received adjuvant radiotherapy and chemotherapy or tamoxifen. If possible, the locoregional recurrence was treated with surgery and/or radiotherapy, otherwise by systemic therapy. RESULTS: Median follow up was 10.4 years; 78 patients developed distant metastases (soft tissue, 32%; bone, 45%; viscera 40%). Median time to dissemination was 4.4 years, and the ten year dissemination rate was 72%. Median time to dissemination was 3.7 years for patients with recurrence in the regional nodes compared to 6.5 years for patients with chest wall recurrence only, p = 0.05. No specific time sequence (temporal pattern) was observed in the anatomical distribution of metastases, and the anatomical site of recurrence could not be predicted by any of the prognostic factors. At follow up, 93 patients had died. The median survival was 5.6 years and 30% were alive after 10 years. Forty-three of the 99 patients who received local therapy only did not develop metastases. Fifteen of these patients died without evidence of metastatic disease while 28 patients were still alive without distant recurrence after a median follow up time of 9.3 years (range, 6.5-11.9 years). Level of LDH and the number of positive regional nodes (NPOS) at primary diagnosis were significant independent prognostic factors for survival after recurrence. CONCLUSIONS: Approximately one third of the patients receiving local treatment only, were alive and without distant metastases up to ten years after locoregional recurrence, indicating that there is a subset of patients which may be long term survivors after local treatment only (surgery or radiotherapy). The duration of survival can be estimated by LDH and NPOS, but the model needs validation in a separate data set before clinical use.

RESUMEN

BACKGROUND AND PURPOSE: The optimal treatment of elderly patients with bladder cancer is not established. This study aimed to evaluate prognostic variables for survival and morbidity, which may be important for treatment strategy. MATERIAL AND METHODS: The medical records of 94 patients aged > or = 75 years receiving curatively intended radiotherapy for bladder cancer were reviewed retrospectively. RESULTS: Median age was 78 years (range 75-93 years). Fifty patients had T1-2 tumors, and 42 patients had T3-4 tumors. The total planned dose was 57.6-62.6 Gy in 24-30 fractions in 6 weeks. In 76 patients, a 2 week rest period was planned after 16 fractions (split course). Half of the patients were hospitalized during or after the treatment because of gastrointestinal or urogenital side effects. Median survival was 13.9 months (range 0.6-150.0 + months), 29% survived for 2 years and 7% survived for 5 years. Patients aged > 78 years survived for a shorter period than patients aged 75-78 years (13.4 versus 16.1 months). Univariate survival analysis revealed that low stage (T1-2), good performance status (PS < or = 1), split course treatment, no treatment interruption due to side effects, and no hospitalization during treatment were associated with long survival. In multivariate analyses, T-stage, split course treatment, and performance status were independent prognostic factors. CONCLUSION: The results confirm that curative intended radiotherapy is feasible in elderly patients, but patients with stage T3-4 and PS > 1 have a short survival. These patients should be offered palliative treatment.

RESUMEN

Thirty-six patients with advanced epithelial ovarian cancer received epirubicin as second-line therapy after primary treatment with carboplatin and cyclophosphamide. Thirty-four patients were evaluatable for response, 36 for toxicity. There were 9 responses (response rate 26.4%, 95% CI = 12.9-44.4), 2 complete and 7 partial. Median duration of response was 149 days (range 42-183); 4 patients with partial remission are still on study. Toxicity consisted of fatal cardiac failure and paravenous injection (1 patient), fatal leukopenia and sepsis (1 patient), and severe loss of appetite, nausea and vomiting, fatigue, and general malaise in 3 patients. Platelet nadir grade 4 (WHO) was observed in 2 patients while leukocyte nadir grade 4 was seen in 3 patients. The present study showed a high response rate from standard-dose epirubicin. Toxicity was acceptable in most patients, but 2 patients died from treatment complications which gives a treatment-related mortality rate of 6%. Response was primarily seen in patients with minor tumor load and in good general condition.
