ALB and sarcopenia: Multivariate analysis showed that (Table 6), KPS score < 80 (HR 2.56, 95%CI [1.27–5.16], p = 0.009), albumin <40.0 g/L (HR 1.98, 95%CI [1.23–3.18], p = 0.005), N stage (2-3) (HR 1.94, 95%CI [1.17–3.20], p = 0.010) and sarcopenia (HR 2.54, 95%CI [1.40–4.63], p = 0.002) lived for a shorter PFS time.
