Abstract:
Objective To establish a clinical scoring system for the prognosis of patients with single large hepatocellular carcinoma (HCC) after hepatectomy.Methods 268 patients with single large HCC who underwent hepatectomy in West China Hospital of Sichuan University from January 2009 to December 2013 were included in this prospective study. There were 227 males and 41 females, of which 198 cases aged≤60 years old, 70 aged>60 years old. The informed consents of all patients were obtained and the local ethical committee approval was received. The patients' survival were observed. The independent risk factors for postoperative prognosis of patients with single large HCC were selected by Cox proportional risk regression mode. Based on the risk factors, the prognostic scoring system for single large HCC wasestablished. The scoring system was tested through survival analysis by Kaplan-Meier and Log-rank test. Results The median overall postoperative survival was 45 months, and the tumor-free survival was 31 months. Platelet-to-lymphocyte ratio (PLR)≥107, tumor diameter≥6.8 cm and positive microvascular invasion (MVI) were the independent risk factors for postoperative overall survival and tumor-free survival in patients with single large HCC (HR=1.004, 1.092, 2.233 and 1.003, 1.062, 1.534; P<0.05). Every independent risk factor was assigned 1 point. All patients were divided into low risk group (0 point), moderate risk group (1-2 points) and high risk group (3 points). The 5-year survival rate of high risk group was 25.4％, and that of moderate and low risk group was 33.2％ and 52.1％ respectively, where significant difference was observed (χ2=23.1, P<0.05). Similar Results were observed when the scoring system was used in patients with or without cirrhosis.Conclusions PLR≥107, tumor diameter≥6.8 cm and positive MVI are the independent risk factors for the prognosis of patients with single large HCC after resection. The prognostic scoring system established in this study can be used to predict the postoperative long-term survival of patients.
