ALB and sarcopenia: In the univariate analysis, sarcopenia (HR 1.865, 95% CI 1.238–2.811, P = 0.003), decreased SMI (HR 1.569, 95% CI 1.023–2.407, P = 0.039), ECOG 2 (HR 1.922, 95% CI 1.212–3.047, P = 0.008), overall response rate (ORR) (HR 0.509, 95% CI 0.322–0.805, P = 0.004) and low albumin (HR 1.592, 95% CI 1.054–2.407, P = 0.027) were significant prognostic factors for survival.
