A total of 3378 older patients (aged \u226560 years) were enrolled. We extracted the patients\u2019 demographics, characteristics of disease, treatment\u2010related variables and indexes of laboratory examination. Receiver operating characteristic analysis was carried out to find the optimum cut\u2010off value for serum albumin.

Surgical site infection prolonged hospitalization of patients by a mean of 14.2 days. The overall incidence was 3.64%, with 0.47% for deep infection and 3.16% for superficial infection.
