H2AX and hepatocellular carcinoma: To investigate the clinicopathologic features of γ-H2AX in HCC and to determine whether γ-H2AX expression in HCC was associated with tumor-free survival and overall post-transplanted survival, all 57 patients with HCC after LT were divided into two groups: the high-expression group (n = 36) and low-expression group (n = 21).
