Introduction and objectivesImproving the prognosis of patients with hepatocellular carcinoma (HCC) undergoing hepatectomy is critical. This article aims to investigate the risk factors affecting the prognosis of HCC patients with Child-Pugh A (CPA) liver function after hepatectomy and to compare the prognosis of patients with anatomical resection (AR) and nonanatomical resection (NAR). MethodsIn total, 186 patients diagnosed with HCC between 2013 and 2019 were retrospectively enrolled. Univariate and multivariate analyses were performed using a Cox proportional hazard regression model to explore the factors related to prognosis. Overall survival (OS) and progression-free survival (PFS) were analyzed by log-rank tests and are shown by Kaplan-Meier curves. Chi-square tests and Mann-Whitney U tests were used to compare the difference in clinical characteristics between AR and NAR patients. ResultsAmong the 186 enrolled patients, only 73 were followed over 60 months. The 1-, 3-, and 5-year survival rates were 74.5%, 46.7% and 26.0%, respectively. Multivariate analyses demonstrated that portal vein invasion (PVI) and tumor size were independent risk factors for OS and PFS. Preoperative hepatitis B surface antigen (HBsAg) and a-fetoprotein (AFP) levels were identified as independent risk factors only for PFS. In univariate analysis, the NAR group had a better OS rate than the AR group (1-year: 80.4% vs. 63.6%, 3-year: 55.9% vs. 30.3%, 5-year: 34.8% vs. 11.1%), but this was not confirmed by multivariate analysis. ConclusionsPVI and tumor size > 5 cm are risk factors for the prognosis of CPA HCC patients after hepatectomy, but the surgical type is not.
