Prognostic factors of patients after liver cancer surgery: Based on Surveillance, Epidemiology, and End Results database

This study aimed to investigate the prognostic factors of patients after liver cancer surgery and evaluate the predictive power of nomogram. Liver cancer patients with the history of surgery in the Surveillance, Epidemiology, and End Results database between 2000 and 2016 were preliminary retrieved. Patients were divided into the survival group (n = 2120, survival ≥5 years) and the death group (n = 2615, survival < 5 years). Single-factor and multi-factor Cox regression were used for analyzing the risk factors of death in patients with liver cancer after surgery. Compared with single patients, married status was the protective factor for death in patients undergoing liver cancer surgery (HR = 0.757, 95%CI: 0.685–0.837, P < .001); the risk of death in Afro-Americans (HR = 1.300, 95%CI: 1.166–1.449, P < .001) was higher than that in Caucasians, while the occurrence of death in Asians (HR = 0.821, 95%CI: 0.1754–0.895, P < .0012) was lower; female patients had a lower incidence of death (HR = 0.875, 95%CI: 0.809–0.947, P < .001); grade II (HR = 1.167, 95%CI: 1.080–1.262, P < .001), III (HR = 1.580, 95%CI: 1.433–1.744, P < .001), and IV (HR = 1.419, 95%CI: 1.145–1.758, P = 0.001) were the risk factors for death in patients with liver cancer. The prognostic factors of liver cancer patients after surgery include the marital status, race, gender, age, grade of cancer and tumor size. The nomogram with good predictive ability can provide the prediction of 5-year survival for clinical development.
