Screening of <i>H‐ras</i> Gene Point Mutations in 50 Cases of Bladder Carcinoma

Abstract

The prevalence of point mutations at codon 12 or codon 61 of the H-ras gene found in this study was similar to that previously estimated for human bladder cancer by DNA transfection assay. The method we have used for detecting point mutations of the H-ras gene provides a simple and highly accurate way to detect mutated cancer cells even in the urine. It may be clinically usable for early diagnosis of bladder cancer.
