Sumario: | BACKGROUND: In real-world practice, eribulin mesylate provides significant survival benefit, with a manageable safety profile in heavily pretreated patients with metastatic breast cancer (MBC). METHODS: In this prospective, open-label, multicentre, observational study we evaluated the effectiveness and tolerability of eribulin as third-line treatment in a homogeneous population. The primary endpoints were the safety profile and response in metastatic sites; secondary endpoints included the response in different subtypes, overall response rate (ORR), progression-free survival (PFS) and overall survival (OS). RESULTS: From 2013 to 2016, 118 women were treated in 21 Sicilian institutions; the median age was 58 years (range 29–79), with 69% of patients under 65. The median cycles of eribulin were 5.5 (range 1–26). The most common adverse event was neutropenia (9.3%, 3 cases of grade 3, 4 of grade 4); only 1 case of QT prolongation was reported. Eribulin was effective in controlling metastatic disease in all sites, and it achieved the highest ORR in brain (16%) and liver (14.9%). Median OS was 31.8 months (95% CI 27.9–34.4) and median PFS 5.5 months (95% CI 4.2–6.6). PFS was 5.2 months (95% CI 2.8–8.4) in patients with triple-negative subtype. Median PFS was longer in patients over 65 years (6.1 months, 95% CI 4.4–8.3). In patients who had visceral metastases PFS was 5.5 months (95% CI 95% 3.5–6.6) and OS 33.9 months (95% CI 29.8–40.8). CONCLUSIONS: Eribulin as third-line treatment shows an acceptable safety profile and a substantial antitumour activity in the treatment of MBC, even in elderly patients and in those with visceral disease. |
