AbstractObjective: To examine clinical efficacy and prognostic factors of hepatocellular carcinoma(HCC) patients with different China Liver Cancer Staging (CNLC) after hepatectomy. Methods: From January 2010 to December,2019,549 patients underwent surgical resection and pathologically proven HCC were retrospectively reviewed in the First Affiliated Hospital of Nanjing Medical University. There were 462 males(84.2%) and 87 females(15.8%);the median age was 57 years (range: 21-84 years). Preoperative parameters,intraoperative and postoperative conditions,and postoperative pathological examination were observed.Survival analysis was performed by Kaplan-Meier method and the Log-rank test. Factors associated with disease-free survival(DFS) and overall survival(OS) of HCC patients were identified using univariate and multivariate Cox proportional hazards regression models. Results: Among the 549 patients underedwent liver resection,200 patients(36.4%) belonged to CNLC Ⅰa,whiles 148 patients(27.0%) belonged to CNLC Ⅰb. Furthermore,there were 49 patients(8.9%) with CNLC Ⅱa,32 patients(5.8%) with CNLC Ⅱb, 101 patients(18.4%) with CNLC Ⅲa and 19 patients(3.5%) with CNLC Ⅲb.The 1-,3-,5-,10-year OS for the entire cohort was 83.8%,69.0%,54.2%,37.7%,respectively,while 1-,3-, 5-year DFS was 61.0%,44.2%,36.0%, respectively. The 1-,3-, 5-year OS and DFS for CNLC Ⅰa were 97.3%,90.6%,80.5% and 83.9%,65.0%,54.0%,respectively;The 1-, 3-, 5-years OS and DFS for CNLC Ⅰb were 87.9%,71.0%,47.7%,and 58.4%,42.3%,33.4%,respectively.The 5-year OS for CNLC Ⅱa (37.2%) and Ⅱb(44.3%) were similar to CNLC Ⅰb. The 1-, 3-, 5-year OS and DFS for CNLC Ⅲb were 35.3%,13.2%,0 and 23.5%,0 and 0,respectively. Univariate analysis showed that preoperative symptoms,AFP level,total protein level,AST level,total bilirubin level,intraoperative blood loss,intraoperative or postoperative blood transfusion,postoperative complications,tumor number and size,microvascular invasion,macrovascular invasion and tumor differentiation were prognostic factors for long-term survival(≥5 years)(all P<0.05). The multivariate analysis suggested that AST level,intraoperative blood loss,tumor number and size,macrovascular invasion and tumor differentiation were the independent prognostic factors of long-term OS (all P<0.05). Conclusions: HCC patients with different stages of CNLC have different recurrence patterns and prognosis.After strict preoperative evaluation,patients with CNLC Ⅱa-Ⅲb can also benefit from radical resection. AST level,intraoperative blood loss,tumor number,tumor size,macrovascular invasion and tumor differentiation were independent factors that affect long-term survival. This will provide an important basis for the choice of treatment and the evaluation of surgical prognosis for patients with HCC.
