Abstract:
e11573 Background: Several studies suggest that newer therapies can improve survival in MBC, but a different impact on overall survival (OS) is observed according to histology, extension of disease and prognostic factors. This survey was performed for evaluate Italian experience in cancer treatment in the last ten years. Methods: We collected data from 13 Italian Medical Oncology Unit; we registered all consecutive patients (pts) with breast cancer who have developed metastasis between 2000 and 2008. Demographic data, pathological characteristics and treatment were reported. OS was calculated from time of recurrence and stratified according to biological characteristics and to recurrence date. Results: 1542 pts was suitable for analysis; median age 61,7 (range 22-94); MBC at diagnosis 21,8%. Site of disease recurrence: bone 26,2%, visceral 25,4%, bone and visceral 20,7%, soft tissue 11,5%, soft tissue and visceral 8,4%, bone and soft tissue 7,8%. Molecolar classification: luminal A 66,3%, luminal B 14,5%, triple negative 11,5%, HER2+ like 7,7%. Pts received a median of 2 lines of chemotherapy (range 0-10) and 1 line of hormonal therapy (range 0-7); 22,5% received biological drugs. 15,5% of metastatic pts were enrolled in clinical trials. After a median follow up of 7.1 years 84,1% pts died (1297/1542 pts) and median OS was 2,7 years (range 2,6-2,9). We did not observe difference in OS for pts divided into 3 groups according to recurrence date (2000-2002, 2003-2005, 2006-2008). A longer median OS was observed in luminal B (3,8 years) versus luminal A and HER2+ like (2,8 years) and triple negative disease (1,2 years). Conclusions: Our survey describe a large number of MBC pts treated in 13 Italian Oncology Unit. OS analysis did not show significant differences according to recurrence date, but for different prognostic factors. OS data are superimposable to literature ones, showing a good transfer from clinical trials to clinical practice.
