Germline polymorphism of p53 codon 72 in gynecological cancer.
OBJECTIVE
To investigate the biological significance of single nucleotide polymorphism at codon 72 of the p53 gene in the development of gynecological cancer.


METHODS
p53 codon 72 polymorphism was examined in a total of 354 blood samples from 95 normal, 83 cervical, 108 endometrial and 68 ovarian cancer cases using polymerase chain reaction and restriction fragment length polymorphism techniques.


RESULTS
When p53 codon 72 genotype was classified into two subgroups of Arg/Arg and Arg/Pro + Pro/Pro, the Arg/Arg genotype was associated with an increased risk for the development of endometrial cancer (OR = 1.86, 95% CI = 1.06 to 3.26) compared with the Arg/Pro + Pro/Pro genotype (P = 0.0301). The Arg allele also increased the risk of endometrial cancer (OR = 1.42, 95% CI = 0.93 to 1.52) compared with the Pro allele, but no statistical difference was found (P = 0.1031). There was no significant difference in the genotype or allele prevalence between control subjects and cervical or ovarian cancer patients.


CONCLUSIONS
Homozygous Arg at codon 72 of the p53 gene may be a risk factor for developing endometrial cancer in a Japanese population.
