Abstract:
Objective To study the expressions of Cx43,CD105 and VEGF in HBV related HCC tissues and the relationships between Cx43 expression and recurrence and prognosis after cancer radical resection in HCC patients stratified by serum AFP levels. Methods The expressions of Cx43,CD105,VEGF in 234 HBV related HCC tissues were examined by tissue microarray and two-step methods of PV-6000 of immunohistochemistry and the expressions of Cx43 in 20 frozen HCC specimens were examined by RT-PCR. Results Cx43 in HCC tissues was positive as examined by both immunohistochemistry and RTPCR methods.Positive Cx43 expression is correlated with lower early recurrence ( Log Rank P =0.001 ),longer disease free survival (Log Rank P =0.026 ) and overall survival( Log Rank P =0.000 ) as showed by the Kaplan-Meier analysis in patients with AFP ＜ 400 μg/L. The expression of Cx43 is an independent prognostic factor.The positive expression of Cx43 related with lower positive expression of CD105 and VEGF (P =0.018,0.023 ),and correlated with histological differentiation (P =0.002),the number of focus (P =0.033 ),blood vessel tumor embolism ( P =0.029 ). Conclusions The expression of Cx43 is correlative with the expression of CD105 and VEGF,and is predictive of HCC early recurrence and poor prognosis after radical hepatectomy in HBV related HCC patients with serum AFP ＜ 400 μg/L.
