In the multivariable analysis, sarcopenia was an independent prognostic factor of poor OS (hazard ratio, 1.51, p = 0.029); no response to chemotherapy (p < 0.001), no second-line chemotherapy (p < 0.001), metastatic sites ≥ 3 (p < 0.001), and low serum albumin level (p = 0.033) were also independent prognostic factors of poor OS. Here, ALB is linked to sarcopenia.
