ABSTRACT
BACKGROUND:
Few therapeutic options are approved as second-line treatment after failure of platinum-based chemotherapy for patients with extensive-stage small-cell lung cancer (ES-SCLC). Topotecan widespread use remains challenged by the risk of severe toxicities in a pretreated population. Little is known about the efficacy and safety of epirubicin-paclitaxel doublet in second-line and beyond and especially cerebral outcomes.METHODS:
EpiTax is a retrospective multicenter observational real-life study. We evaluated the efficacy of epirubicin 90 mg/m2 combined with paclitaxel 175 mg/m2 every 3 weeks in SCLC patients after failure of at least one line of platinum-based chemotherapy. The primary endpoint was progression-free survival (PFS). Secondary endpoints were overall survival (OS), objective response rate (ORR), disease control rate (DCR), intracranial control rate (ICR), and safety.RESULTS:
A total of 29 patients were included. The median of previous systemic therapy lines was 2 (1-4). Eleven patients received the treatment in the second line. Characteristics of patients were a median age of 60 years (45-77), 65.5% of males with 72.4% of PS 0-1. Fifteen patients had a history of brain metastases. Median PFS and OS achieved 11.0 (95% CI, 8.1-16.3) and 23 (95% CI, 14.1-29.6) weeks, respectively. ORR was 34.5% and DCR was 55.2%. ICR was 3/15 (20%). Grade 3-4 adverse events were mainly hematological and concerned 7 patients. No case of febrile neutropenia or toxic death was reported.CONCLUSION:
Epirubicin-paclitaxel association highlighted promising efficacy with PFS and OS of 11 and 23 weeks, respectively, ORR of 34.5%, and a tolerable safety profile. This doublet could represent another valuable therapeutic option for ES-SCLC patients treated in the second line and beyond.Key words
