Close correlation between a p53 or hMSH2 gene mutation in the tumor and survival of hepatocellular carcinoma patients

Int J Oncol. 1999 Mar;14(3):447-51. doi: 10.3892/ijo.14.3.447.

Abstract

We analyzed 42 hepatocellular carcinomas (HCC) (38 patients) for mutations in the DNA mismatch repair gene hMSH2 and the p53 tumor suppressor gene, a possible upregulater of hMSH2. Mutations of the hMSH2 or p53 gene were detected in 13 patients (34%). There were no patients who possessed mutations in both genes. There was a significant correlation between mutation of either gene and pathological indicators of malignancy. The survival rate of patients with hMSH2 or p53 gene mutation-positive tumors was much poorer than that with hMSH2 and p53 gene mutation-negative tumors (p=0.0012). Our results suggest that mutations in the p53 or hMSH2 gene may closely correlate with the survival of hepatocellular carcinoma patients.
