A high prevalence of p53 mutations in pre-malignant oral erythroplakia

Abstract excerpt

Oral squamous-cell carcinoma is thought to be preceded by a number of precursor stages which induce morphological changes in cells of the oral mucosa resulting in clinically detectable pre-malignant lesions such as erythroplakia or leukoplakia. To better understand the etiology of oral erythroplakia, we have examined the p53 tumor-suppressor gene (exons 5-9) for mutations in 24 oral erythroplakia lesions of...
