[The risk of endometrial cancer appearance and CYP19 and COMT gene polymorphism]

Women with high circulating estrogens concentration have increase risk of breast, endometrium and ovarian cancer, thus it is important to identify factors, including environmental and genetic variability that may be alter estrogen concentration.In the present work the distribution of genotypes and frequencies of alleles of the T/C polymorphism of CYP19 and G/A polymorphism of COMT gene in subjects with endometrial cancer were investigated. Paraffin embedded tumour tissues was obtained from 151 postmenopausal women with endometrial cancer. The polymorphism's were determined by PCR-RFLP methods.The distribution of the genotypes of the T/C and G/A polymorphism in both control and patients did not differ significantly (p0.05) from those predicted by the Hardy-Weinberg distribution. Additionally, there were no significant differences (p0.05) in genotype distributions and allele frequencies between subgroups assigned to histological stage.The results suggest that the CYP19 and COMT polymorphism may not be linked with appearance and development of endometrial cancer but further research, conducted on larger population, are needed to clarify this point.
