Analysis of p53 gene mutation by polymerase chain reaction-single strand conformation polymorphism provides independent prognostic information in node-negative breast cancer.

Abstract excerpt

Controversy continues regarding the prognostic utility of detection of p53 gene abnormalities in node-negative breast cancer. To resolve this, we used a rapid and nonisotopic PCR-single strand conformation polymorphism method to screen for mutations in exons 4-8 of the p53 gene in primary tumors from 422 node-negative breast cancer patients. The prevalence of p53 mutation in the exons tested was 18%. p53 mutation...
