Breast cancer is the most frequent cancer in women: in 2018, almost two million cases have been diagnosed all over the world and it represents the principal cause of death from a neoplastic disease in women. In the past years, breast cancer prognosis has significantly improved over time: currently 5-year survival rates are in the range of 90%, and 10-year survival is about 80%. This improvement has been mostly observed in western countries, due to high coverage and compliance with screening programs, leading to early diagnosis, i.e., when the disease is at a subclinical level, and to an improvement in tumor molecular characterization and innovative systemic treatments. Yet the identification of different biological breast cancer subtypes prompted the development of innovative targeted agents and improved treatment personalization. On the other hand, longer survival rates and increasing proportions of cured patients require dedicated strategies to manage long-term sequelae of breast cancer treatments, with particular attention to quality of life. This review analyzes the most important issues, potentially occurring with cancer treatments, concerning long-term sequelae and quality of life, to define a global approach to breast cancer survivorship.
This retrospective multicenter analysis was aimed to evaluate clinical activity and tolerability of eribulin in pretreated metastatic breast cancer patients in clinical practice. Patients treated with eribulin from January 2012 to July 2013 were enrolled in the observational study from 10 italian hospitals. Tumor and toxicity evaluation were performed according to Agenzia Italiana Farmaco. One-hundred and thirteen patients were included in the study. Median age 62 years old. 71.7 % of the patients had visceral involvement and the majority had a burden of disease involving two or more organs with a median number of 2 (1–6). The median number of previous chemotherapy regimens for advanced disease was 3 (1–10). Median number of eribulin cycles was 4 (1–27). Overall response rate was 24 % (95 % CI 16.0–31.8). Clinical benefit rate, was 35.4 % (95 % CI 26.6–44.2). At a median follow-up of 29.6 months (8.3–41.9) the median progression free survival was 3.3 months (0.6–26.7; 95 % CI 2.4–4.2), and the median overall survival 11.6 months (0.6–33.3; 95 % CI 8.7–14.5). No correlation was recorded between subtypes in terms of ORR and CBR. Toxicity was manageable. Main common grade 3–4 toxicities were neutropenia (19.4 %), febrile neutropenia (0.9 %), asthenia (3.5 %), abnormal liver function test (1.8 %), stomatitis (0.9 %). Our results confirm that treatment with eribulin is feasible and safe in real-world patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
