Abstract:

Objective To explore the relationship between the expression of Ki67 in hepatocellular carcinoma (HCC) tissues and the prognosis of liver transplantation (LT) in patients with HCC. Methods The clinical data and results of immunohistochemical staining of 178 patients with HCC who underwent orthotopic liver transplantation between July 2014 and June 2018 were collected. According to the median expression level of Ki67 in tumor tissues, patients were divided into the Ki67 high expression group and the Ki67 low expression group. The clinical parameters were compared between the two groups. Kaplan-Meier methods was used to plot survival curves to compare the prognosis of the two groups of patients. Univariate and multivariate Cox regression were used to analyze risk factors affecting the prognosis of patients after LT. Results Among the 178 patients in this study, 85 were in the Ki67 high expression group and 93 were in the Ki67 low expression group. The overall survival (78.7%, 52.6%, 39.5%) and recurrence-free survival (47.9%, 34.7%, 32.0%) were significantly lower in patients in the Ki67 high expression group than those in the Ki67 low expression group (86.5%, 76.3%, 76.3%; 84.4%,77.5%,72.4%), Log-rank χ2 were 9.016 and 28.467, respectively (P<0.01). Cox multivariate analysis showed that the high expression of Ki67 was an independent risk factor affecting recurrence-free survival (HR=3.653, 95%CI: 1.997-6.683, P<0.01). The incidence of microvascular invasion, poor tumor differentiation and preoperative serum alpha-fetoprotein level were higher in the Ki67 high expression group than those in the Ki67 low expression group (P<0.05). Conclusion The expression of Ki67 is related to the prognosis of HCC patients after LT. Ki67 can be used as a potential indicator to predict the prognosis of HCC patients after LT.
