Background: There are no standard cytotoxic treatments for non-small-cell lung cancer (NSCLC) patients beyond third-line therapy. The purpose of this study was to evaluate the efficacy and safety of amrubicin in pretreated NSCLC patients. Methods: The records of NSCLC patients who received amrubicin monotherapy as a third or later line of chemotherapy at Shizuoka General Hospital between April 2007 and March 2015 were retrospectively reviewed. Tumor response was evaluated according to the Response Evaluation Criteria in Solid Tumors version 1.1. Toxicities were evaluated according to the Common Terminology Criteria for Adverse Events version 3.0. Results: Overall, 69 patients were enrolled in this study; 16 patients were female and the median age was 67 years. The median number of treatment cycles was 3. The response rate was 7.2%, and the disease control rate was 63.8%. The median progression-free survival was 2.8 months. The median overall survival was 7.7 months. Hematological toxicities of ≥ grade 3 included leukopenia (59.4%) and neutropenia (62.3%). Non-hematological toxicities of ≥ grade 2 included anorexia (27.5%) and fatigue (24.6%). Conclusion: Although hematological toxicities were severe, these results suggested that amrubicin in NSCLC patients beyond third-line therapy shows sufficient clinical benefit.
