No association betweenP53codon 72 polymorphism and risk of squamous cell carcinoma of the head and neck

An initial report suggested that patients homozygous for the arginine allele at codon 72 ofP53were at increased risk for human papillomavirus (HPV)-related cervical cancer, but other groups have not confirmed this finding. Since approximately 18–36% of head and neck cancers are HPV-related, we exami...

Sumario:An initial report suggested that patients homozygous for the arginine allele at codon 72 ofP53were at increased risk for human papillomavirus (HPV)-related cervical cancer, but other groups have not confirmed this finding. Since approximately 18–36% of head and neck cancers are HPV-related, we examined the genotypic frequencies at that locus in 163 cases with squamous cell carcinoma of the head and neck (SCCHN) and 163 ethnically matched controls. We found no significant excess of arginine homozygotes in cases compared to controls (P= 0.50). No significant differences in allele frequencies were observed when the data were stratified by tobacco exposure or by cancer site. These findings suggest a limited role, if any, for thisP53polymorphism in SCCHN.© 2000 Cancer Research Campaign
