Prognostic influencing factors in patients of Barcelona stage B hepatocellular carcinoma undergoing hepatectomy

Objective To investigate the prognostic factors that influence Barcelona (Barcelona clinical liver cancer staging system, BCLC)stage B hepatocellular carcinoma patients after hepatectomy. Methods Retrospective analysis was made on clinical and pathological data of 50 standardized hemihepatectomy in Barcelona stage B hepatocellular carcinoma from 2013 to 2017. Results Single-factor results showed that high expression of tumor microvascular invasion (MVI) and proliferation of nuclear antigen (Ki-67) were the prognostic factors ( respectively χ2 =8.411, 10.939, all P<0.05). Multivariate analysis showed that the difference of high expression of Ki-67 and survival rate was statistically significant (respectively F=5.710, 8.254, all P<0.05). Ki-67 expression level and tumor differentiation were statistically significant (χ2=0.497, P<0.05). There was a statistically significant difference in survival between the high-risk group and the low-risk group according to the risk factors (χ2=12.152, P<0.05). Conclusions MVI and high expression of Ki-67 were high risk factors affecting the overall survival rate of liver cancer after hemihepatectomy.
