Abstract

The efficacy and safety of eribulin in Japanese patients with advanced soft-tissue sarcomas (STS) have not been evaluated in a large-scale cohort study. Thus, we aimed to investigate the clinical outcome of 82 Japanese patients with STS receiving eribulin across multiple study centers retrospectively. Of 82 STS patients receiving eribulin treatment, 13 were treated for locally unresectable tumor, 46 for metastasis, and 23 for both. The primary endpoint of this study was to evaluate the efficacy of eribulin against STS. The median age was 60 years. Thirty-seven were diagnosed with L-sarcoma (leiomyosarcoma or liposarcoma) and 45 had non-L-sarcoma. The median progression-free survival (PFS) for all patients was 2.7 months, with 3.4 months in those with L-sarcoma and 2.2 months in those with non-L-sarcoma. Patients with L-sarcoma showed a better PFS than those with non-L-sarcoma. Overall, the median survival time was 11.1 months, and 12.3 months and 7.9 months in patients with L-sarcoma and non-L-sarcoma, respectively; however, there was no significant differences between the groups. The prognostic significance of PS = 0 and both existence of local and metastatic STS was evaluated by multivariate analysis. We also evaluated the overall survival (OS) in patients with undifferentiated pleomorphic sarcoma (UPS) and other non-L-sarcomas. Patients with UPS had better OS than those with the other non-L-sarcomas. In conclusion, there was a significant difference in PFS between patients with L-sarcoma and non-L-sarcoma following treatment with eribulin. The anti-tumor potential of eribulin was evident in patients with UPS.
