ABSTRACT

PURPOSE: Combining bevacizumab with paclitaxel significantly improves progression-free survival (PFS) versus paclitaxel alone in HER2-negative metastatic breast cancer (MBC). Eribulin is active and tolerable in pretreated MBC. To assess whether eribulin may offer a more tolerable yet effective combination partner for bevacizumab, we evaluated a bevacizumab/eribulin combination regimen as first-line therapy for MBC. METHODS: In this single-arm phase II study, patients with histologically confirmed HER2-negative MBC and no prior chemotherapy for MBC received eribulin 1.23 mg/m2 on days 1 and 8 every 3 weeks for ≥6 cycles plus bevacizumab 15 mg/kg on day 1 every 3 weeks until disease progression. The primary endpoint was non-progression rate at 1 year. Secondary endpoints included objective response rate (ORR), PFS, and safety. RESULTS: The median age of the 61 treated female patients was 59 years, 16% had triple-negative MBC, 30% had ≥3 metastatic sites, and 71% had received prior (neo)adjuvant chemotherapy. Patients received a median of six eribulin and nine bevacizumab cycles. The non-progression rate at 1 year was 32% (95% confidence interval [CI]: 20-43%), ORR was 47% (95% CI: 34-60%), and median PFS was 8.3 months (95% CI: 7.0-9.6 months). The only grade ≥3 clinical adverse events in >5% of patients were hypertension (39%), neutropenia (26%), thrombosis (10%), and paresthesia/dysesthesia (7%). CONCLUSION: First-line eribulin/bevacizumab combination therapy showed interesting activity in MBC with an acceptable safety profile, including a particularly low incidence of high-grade neuropathy.

ABSTRACT

BACKGROUND: Expression IV survey evaluated the patients' expectations to a maintenance therapy. METHODS: From January 2015 to March 2016, 401 French patients, in first line or recurrent disease, answered a 24-items anonymous questionnaire. The results were specifically analyzed according to the demographic characteristics and treatment lines. RESULTS: Among the patients, 62% had already been informed about maintenance therapy. Thirty-seven percent of patients received a maintenance treatment: 111 patients during first line and 39 patients in relapse. Expectations of patients were: 1) the chance of cure (73%), 2) the tumor shrinkage (36%), 3) quality of life improvement (35%) and 4) tumor growth reduction (27%). Among the responders, 42% were willing to take the treatment for 6-24 months, 20% for 24-60 months and 38% until tumor progression. 64% of patients expected more than a 6 months progression-free survival. Patients older than 70 years were less informed than their younger counterparts (48% vs 66%) and had lesser hope for cure with maintenance treatment (60% vs 77%). Patients in relapse had more expectation than patients in remission (tumor shrinkage: 47% vs 22%, slowing of tumor growth: 37% vs 15%, improving the progression-free survival of more than 6 months: 71% vs 53%, respectively). Among patients, 48% in relapse consented to take a treatment until progression vs 24% of patients in remission. CONCLUSION: This sub-analysis in French patients demonstrate a gap between the efficacy of maintenance therapy and the patients' expectations in ovarian cancer, particularly in relapsing disease justifying better information and explanations.
