17β-hydroxysteroid dehydrogenase type Gene 1937 A > G Polymorphism as a Risk Factor for Cervical Cancer Progression in the Polish Population.

The role of 17β-estradiol (E2) in the development of cervical tumor (CT) has been demonstrated. 17β Hydroxysteroid dehydrogenase type 1 (HSD17B1) converts estrone (E1) into E2. We aimed to study the distribution of the HSD17B1937 A > G (rs605059) single nucleotide polymorphism (SNP) in women (n = 383) with CT and controls (n = 401) from the Polish population. The p-trend value evaluated for HSD17B1 rs605059 was 0.0233 for all patients. The A/A vs G/G genotype significantly contributed to all patients with CT, and the Odds Ratio (OR) was 1.570 (95 % CI = 1.053-2.343; p = 0.0266). Stratification of the patients based on tumor stage and histological grade indicated the contribution of HSD17B1937 A > G to stages III and IV. The p-value was 0.0010. The OR for the A/A vs G/G genotype was 2.992 (95 % CI = 1.627-5.502, p = 0.0003), the OR for the A/G vs G/G genotype was 2.545 (95 % CI = 1.410-4.593, p = 0.0015) and the OR for the A/A and A/G vs G/G genotype was 2.724 (95 % CI = 1.546-4.799, p = 0.0004). Moreover, we observed a contribution of the rs605059 SNP to histological grade G3 status. The p-value was 0.0042. The OR for the A/A vs G/G genotype was 5.632 (95 % CI = 1.644-19.290, p = 0.0026), the OR for the A/G vs G/G genotype was 4.213 (95 % CI = 1.244-14.265, p = 0.0113) and the OR for the A/A and A/G vs G/G genotype was 4.780 (95 % CI = 1.456-15.687, p = 0.0033). Our study indicated that the HSD17B1937 A > G transition is a risk factor for CT, especially for stages III and IV and histological grade G3.
