Expression of RASAL2 in hepatocellular carcinoma and the clinical significance / 中南大学学报(医学版)

OBJECTIVE@#To detect the expression of RA SAL2 in patients with hepatocellular carcinoma (HCC), and to investigate the association of RASAL2 expression with pathological characteristics and prognosis.@*METHODS@#Immunohistochemical SP method was used to detect the expression of RA SAL2 in 164 samples of HCC tissue and the adjacent tissue. Th e association of RA SAL2 expression with clinical features and prognosis was analyzed.@*RESULTS@#The expression of RASAL2 in adjacent tissue was significantly increased compared to that in HCC tissue (P0.05). The 5 years recurrence-free survival (RFS) in patients with low expression of RASLA2 was significantly reduced compared with that in patients with high expression of RASLA2 (P<0.001). Cox analysis showed that low expression of RASLA2 was the independent factor for recurrence and death in HCC patients after surgery (P<0.001).@*CONCLUSION@#Low expression of RRASAL2 is significantly associated with the poor prognosis of HCC, which is an independent factor for HCC prognosis.

Correlation between the expression of C-terminal tensin-like protein and the prognosis of hepatocellular carcinoma / 中南大学学报(医学版)

Objective: To explore the correlation between the expression of C-terminal tensin-like protein (CTEN) and the prognosis of hepatocellular carcinoma (HCC). Methods: Using immunohistochemistry, we detected CTEN protein level in samples of primary lesion and adjacent non-tumor lesion collected from 240 patients with HCC. The relationship between CTEN expression and clinicopathology, 5 year recurrent-free survival, or overall survival was evaluated by Chi-square test, Kaplan-Meier, or Cox regression analysis. Results: High CTEN expression was detected in 55% of hepatocellular carcinoma tissues and 20%of adjacent carcinoma tissues (P<0.001). CTEN expression was positively correlated with tumor diameter (P=0.022), venous invasion (P=0.007) or TNM stages (P=0.022). Five-year recurrence-free survival time (P<0.001) and overall survival time (P<0.001) in patients with high CTEN expression were signiifcantly less than those in patients with low CTEN expression. Multivariate Cox regression analysis revealed that the CTEN expression was an independent prognostic marker for HCC (all P<0.05). Conclusion: CTEN protein may play a role in the genesis and development of HCC, and it can function as a prognostic marker.
