Abstract

The association of the p53 polymorphism at codon 72 and susceptibility to develop human papillomavirus (HPV)-related cancer has been investigated in several studies with controversial results. In this study, 78 penile squamous cell carcinoma biopsies ( n = 17 from Uganda, n = 61 from Italy) and blood samples from 150 healthy controls ( n = 57 from Uganda, n = 93 from Italy) have been analyzed for the arginine and proline allele distribution. Among Ugandan cases the heterozygous, proline homozygous and arginine homozygous genotype frequency was 41.2%, 52.9% and 5.9%, respectively, and among controls was 40.3%, 54.4%, and 5.3%, respectively ( P = 0.9917). Conversely, among Italian cases genotype distribution was 42.6%, 4.9%, and 52.5%, and among controls was 34.4%, 7.5%, and 58.1%, respectively ( P = 0.5343). No significant differences in arginine and proline allele distribution were observed when the cases were stratified by HPV status. Therefore, no evidence of association between homozygosity for p53 arginine and HPV-related or HPV-unrelated penile squamous cell carcinoma was observed neither among Ugandan nor among Italian populations.
