Cox regression method was utilized for those analyses, with the following cutoff values for risk factors: age, 65 yrs; BMI, 18.5 kg/m2; tumor heredity, GC family history; HTN, hypertension; DM, diabetes mellitus; C3, 0.75 mg/mL at admission or postoperative day 3; tumor location, up/middle/low 1/3 stomach; TNM stage, I/II versus III/IV; histology, high/moderate/low differentiation; tumor marker, any increased values beyond upper limit of reference range at admission. Multivariate analysis using postoperative C3, pT stage, pN stage, pTNM stage, and tumor marker was performed with Enter mode. makers in digestive malignant diseases, including AFP (0–20 μg/L), CEA (0–5 μg/L), CA125 (0–35 U/mL), CA19-9 (0–35 U/mL), and SCC (0–1.5 μg/L), were measured at admission or follow-up visits.
