Before propensity-matching, there were statistically significant differences in the age (p < 0.0001), BMI (p < 0.0001), NRS2002 (p < 0.0001), albumin (p < 0.0001), LYM% (p = 0.01) and WBC (p = 0.006) between the two groups, but no significant differences were observed in the sex, tumor histological grade, pT Stage, pTNM Stage, comorbidities or type of resection (all p > 0.05) (Table 2). This evidence concerns the gene ALB and neoplasm.
