We performed a single-center retrospective study of sarcoma patients treated with trabectedin with long-term follow-up. In total, 147 sarcoma patients treated with trabectedin were analyzed, with a mean follow-up time of 5 years. At 5 years, increased PD-L1 expression corresponded to worse outcomes (HR = 1.87, p = 0.04, q = 0.199)...high PD-L1 expression were less likely to benefit from trabectedin...
