OBJECTIVE: Eribulin mesylate (Halaven®) is a non-taxane inhibitor of microtubule indicated as monotherapy in patients with metastatic breast cancer (MBC), which progresses after anthracycline and taxanes therapy. In this retrospective observational study, we want to evaluate the efficacy of Eribulin in elderly women with MBC pretreated with anthracyclines and taxanes.

PATIENTS AND METHODS: 40 elderly patients > 70 years of age were enrolled, and the median age was 76 years (range 70-82). Overall survival (OS), Progression Free Survival (PFS), Objective Response Rate (ORR) were primary endpoints, tolerability, carcinoembryonic antigen levels 15.3 (Ca 15.3), before and after treatment, and Quality of Life (QoL) were secondary endpoints.

RESULTS: Eribulin treatment was well tolerated, produced a good level of disease control, a manageable toxicity profile and a significant impact on QoL. Median OS was 12.8 months and median PFS was 3.2 months. A significant correlation was observed between reduction of Ca 15.3 and PFS with a value of 0.59 (p = 0.002).

CONCLUSIONS: Despite a limited number of patients and a modest manageable toxicity, Eribulin is a chemotherapy treatment that has showed to be an effective and well-tolerated therapeutic option in elderly patients with MBC. Further analysis should focus on the elderly patients in our setting of study.
