ABSTRACT
BACKGROUND:
Everolimus (Afinitor®) plus exemestane are indicated for hormone receptor-positive, HER2/neu-negative metastatic breast cancer (MBC), in menopausal women without symptomatic visceral disease after recurrence or progression following aromatase inhibitors. But everolimus efficacy as late treatment has not been explored.METHODS:
Sixty-three MBC patients progressing under hormonotherapy (HT; n = 30) or after chemotherapy (CT; n = 32) received everolimus plus HT (EHT) and were analyzed for safety, efficacy and overall survival (OS). This cohort was compared with our previous 530 MBC patients stratified by line (PMID 21852136).RESULTS:
The median duration of EHT was 27.8 weeks at 5-10 mg/day until clinical progression or toxicity. Median OS was not reached (median follow-up 18 months). Twelve-month survival was 100, 79 and 49% for patients treated with 0 (n = 13), 1-2 (n = 18) and >3 CT (n = 32), respectively. Median time-to-treatment failure was 6.4 months. In 62 EHT patients randomly matched 17 with 421 previous patients for age and number of CT, OS improved compared with patients receiving a new CT (p = 0.062). In patients pretreated with <2 CT, EHT gave a better OS than in those with a new CT (p = 0.026).CONCLUSIONS:
These results may support the use of EHT whatever the number of previous lines.
