However, the role of CA-IX in hepatocellular carcinomas (HCCs) remains largely unknown.We examined the expression of 277 unifocal, resectable, primary HCC tumors using immunohistochemistry. The CA-IX protein was expressed in 110 of the 227 (48.5%) HCC tumors. The expression of CA-IX correlated with younger age (P = 0.0446), female sex (P = 0.0049), high serum α-fetoprotein levels (P<1×10-6), larger tumor size (P = 0.0031), high tumor grade P<1×10-6) and high tumor stage (P = 1.5x10-6). Patients with HCC tumors that expressed CA-IX were more likely to have lower 5-year diseasefree survival (DFS; P = 0.0001) and 5-year overall survival (OS; P<1×10-6). The multivariate analysis indicated that CA-IX expression was an independent predictor for high tumor stage (P = 0.0047) and DFS (P = 0.0456), and a borderline predictor for OS (P = 0.0762). Furthermore, CA-IX expression predicted poor DFS and OS in patients with high tumor stage (P = 0.0004 and P<1×10-6, respectively). Interestingly, CA-IX expression might contribute to the worse prognosis of female patients with advanced HCCs. Our study indicates the expression of the CA-IX protein is a crucial predictor of poor prognosis in resectable HCC, and it is also an unfavorable prognostic predictor in HCC patients with high tumor stage. ? 2015 Huang et al. |
