The median survival of women with metastatic breast cancer (MBC) is 18-24 months, and fewer than 5% are alive and disease free at 5 years.

Abstract
The median survival of women with metastatic breast cancer (MBC) is 18-24 months, and fewer than 5% are alive and disease free at 5 years. We report toxicity and survival in a cohort of MBC patients receiving high-dose chemotherapy (HDC) with autologous hematopoietic SCT (AHSCT) in Italy between 1990 and 2005. Data set for survival analysis has been obtained for 415 patients. Clinical parameters including probability of transplant-related mortality (TRM), PFS and OS. With a median follow-up of 27 months (range 0-172), OS and PFS at 5 and 10 years in the whole population were 47/23 and 32/14%, respectively. A total 239 patients are alive with a median follow-up of 33 months (range 2-174). Survival was significantly more pronounced in patients harboring hormone receptor positive tumors (P=0.028), without visceral metastases (P=0.009) and in women with chemosensitive disease (P<0.0001). Sixty eight patients (20.4%) who received HDC in partial response, stable or progressive disease underwent conversion to CR. TRM was 2.5% overall and 1.3% since 2000. Our findings suggest that could be a role for HDC and AHSCT in delaying disease progression and possibly cure a subset of MBC patient harboring chemosensitive tumors.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
