Abstract:
      Cyclin B2 (CCNB2), a member of the cyclin protein family, has a key role in the progression of G2/M transition. However, the clinical value of CCNB2 in hepatocellular carcinoma (HCC) is still unknown. The aim of our study is to identify the role of CCNB2 in HCC patients. Immunohistochemical analysis using tissue microarray (TMA) was employed to evaluate the expression of CCNB2 in HCC and the correlation between CCNB2 expression and clinicopathological features in HCC patients. The relationship between CCNB2 expression and the prognosis of HCC patients was analyzed using Oncomine and Kaplan-Meier Plotter online resources. High CCNB2 cytoplasmic expression was observed in 77.22% of patients with HCC, which was related to differentiation (P<0.001), tumor diameter (P=0.025), and hepatitis B virus infection (P=0.008). High CCNB2 nuclear expression was seen among 43.43% of cases, which was associated with differentiation (P=0.001). CCNB2 levels were inversely proportional to patient prognosis. The study suggests that CCNB2 expression could be an effective prognostic biomarker for HCC.
