RESUMO

The validated EndoPredict assay is a novel tool to predict the risk of metastases of patients with estrogen receptor positive, HER2 negative breast cancer treated with endocrine therapy alone. It has been designed to integrate genomic and clinical information and includes clinico-pathological factors such as tumor size and nodal status. The test is feasible in a decentral setting in molecular pathology laboratories. In this project, we investigated the performance of this test in clinical practice, and performed a retrospective evaluation of its impact on treatment decisions in breast cancer. During one year, EndoPredict assays from 167 patients could be successfully performed. For retrospective evaluation of treatment decisions, a questionnaire was sent to the clinical partner. Regarding the molecular EP class, samples from 56 patients (33.5%) had a low-risk, whereas 111 patients (66.5%) showed a high-risk gene profile. After integration of the clinicopathological factors the combined clinical and molecular score (EPclin) resulted in a low-risk group of 77 patients (46.4%), while 89 (53.6%) had a high risk EPclin score. The EPclin-based estimated median 10-year-risk for metastases with endocrine therapy alone was 11% for the whole cohort. The median handling time averaged three days (range: 0 to 11 days), 59.3% of the tests could be performed in three or less than three days. Comparison of pre- and post-test therapy decisions showed a change of therapy in 37.7% of patients. 16 patients (12.3%) had a change to an additional chemotherapy while 25.4% of patients (n = 33) changed to an endocrine therapy alone. In 73 patients (56.2%) no change of therapy resulted. In 6.1% of patients (n = 8), the patients did not agree to the recommendation of the tumor board. Our results show that the EndoPredict assay could be routinely performed in decentral molecular pathology laboratories and the results markedly change treatment decisions.

RESUMO

AIM: We describe the impact of a sequential dose-dense schedule of carboplatin and paclitaxel on the quality of life (QoL) of patients with ovarian cancer. PATIENTS AND METHODS: In this multicenter phase II trial, four cycles of carboplatin followed by 12 cycles of weekly paclitaxel were applied after cytoreductive surgery. QoL was assessed using the QoL questionnaires EORTC QLQ-C30 and QLQ-OV28 before chemotherapy (baseline), after four cycles of carboplatin, at the end of treatment (EOT), and after 6, 12, and 24 months. RESULTS: Out of 104 eligible patients 87 (84%) participated in at least one QoL assessment. At baseline, all QLQ-C30 scales and symptoms were significantly worse than age-adjusted values for the general population. Subsequently QoL improved in general. During chemotherapy with paclitaxel, most functioning scales and symptoms worsened slightly (not significantly). However, peripheral neuropathy and chemotherapy-related side-effects increased to clinically important levels. At the end of treatment, most QoL scores were similar to those of the general population, but physical functioning and fatigue were worse. Sexual functioning and peripheral neuropathy remained problematic. CONCLUSION: QoL was affected mainly by the weekly paclitaxel schedule, but effects were in most cases only temporary. A dose-dense regimen using a sequential protocol may be favourable in terms of QoL.

RESUMO

PURPOSE: The management of recurrent ovarian cancer remains controversial. Single-agent topotecan is an established treatment option, and preliminary evidence suggests improved tumor control by combining topotecan with etoposide or gemcitabine. PATIENTS AND METHODS: Women with relapsed ovarian cancer after primary surgery and platinum-based chemotherapy were randomly assigned to topotecan monotherapy 1.25 mg/m(2)/d, topotecan 1.0 mg/m(2) plus oral etoposide 50 mg/d, or topotecan 0.5 mg/m(2)/d plus gemcitabine 800 mg/m(2) on day 1 and 600 mg/m(2) on day 8 every 3 weeks. Patients were stratified for platinum-refractory and platinum-sensitive disease according to a recurrence-free interval of less or more than 12 months, respectively. The primary end point was overall survival. Secondary end points included progression-free survival, objective response rates, toxicity, and quality of life (as measured by the European Organisation for Research and Treatment of Cancer [EORTC] 30-item Quality-of-Life Questionnaire). RESULTS: The trial enrolled 502 patients with a mean age of 60.5 years (+/- 10.2 years), 208 of whom were platinum resistant. Median overall survival was 17.2 months (95% CI, 13.5 to 21.9 months) with topotecan, 17.8 months (95% CI, 13.7 to 20.0 months) with topotecan plus etoposide (log-rank P = .7647), and 15.2 months (95% CI, 11.3 to 20.9 months) with topotecan plus gemcitabine (log-rank P = .2344). Platinum-sensitive patients lived significantly longer than platinum-refractory patients (21.9 v 10.6 months). The median progression-free survival was 7.0, 7.8, and 6.3 months, respectively. Objective response rates were 27.8%, 36.1%, and 31.6%, respectively. Patients under combined treatment were at higher risk of severe thrombocytopenia. CONCLUSION: Nonplatinum topotecan combinations do not provide a survival advantage over topotecan alone in women with relapsed ovarian cancer.

RESUMO

OBJECTIVES: To study the toxicity and efficacy of weekly paclitaxel and carboplatin (PC-W) in women with primary ovarian cancer METHODS: This investigation extended a phase-I dose finding study and was approved by the institutional review boards of all participating institutions. Between 1999 and 2003, women with radically resected ovarian cancer of FIGO stages II B to IV were enrolled at 17 German centres. Patients received weekly paclitaxel at a dose of 100 mg/m2, followed by carboplatin AUC 2. After a first treatment block consisting of six cycles of chemotherapy, patients had a treatment-free interval of 14 days, followed by a second block of six cycles. Treatment was completed by a 28-days break and a final block of six cycles. RESULTS: Altogether, 129 women with a mean age of 59 +/- standard deviation 11 years entered the study. Most patients (82.9%) had serous papillary carcinoma of FIGO stage III (72.9%) and IV (20.9%). Participants received 1,851 cycles of chemotherapy; averaging 14.3 +/- 4.3 cycles each patient. PC-W produced low rates of peripheral neuropathy (grade 3: 2.3%, 95% confidence interval [CI] 0.5-6.6%), with rapid recovery after 3 months. However, 72 patients had grade III/IV anaemia (55.8%, 95% CI 46.8-64.5%). There were 36 events of grade III/IV leukopenia (27.9%, 95% CI 20.4-36.5%). One patient sustained neutropenic fever. CA-125- and objective response was noted in 73.9% (95% CI 64.7-81.8%) and 55.6% (95% CI 41.4-69.1%) of patients. Median progression free and overall survival was 21 and 43 months, respectively. CONCLUSIONS: PC-W is feasible; a randomized study is warranted to compare this new regimen with conventional 3-weekly treatment.
