Abstract

Benign breast disease is a group of all noncancerous mammary lesions with a risk of breast cancer (BC) development. BC is the most common cancer in the world; therefore, it is necessary to find new biomarkers and targets for early diagnosis, treatment, prediction of prognosis and survival. Long non-coding RNA SRA could play this role, thus further studies of its impact on the precancerous lesion pathogenesis are needed.

The aim. To analyze the association between SRA1 rs801460 and rs10463297 SNPs and the occurrence of gynecological pathology among Ukrainian women with the proliferative type of benign breast disease without atypia.

Materials and methods. This study included 115 patients with proliferative type of benign breast disease without atypia: 55 – with gynecological pathology and 60 – without it. Polymerase chain reaction-restriction fragment length polymorphism analysis (PCR-RFLP) was used for polymorphism genotyping.

Hematoxylin and eosin, toluidine blue and van Gieson’s picrofuchsin methods were applied for staining of sections. Statistical analysis was carried out using Statistical Package for the Social Sciences software (SPSS, version 25.0, Chicago, IL, USA).

Results. Significant differences were found in the rs10463297 frequency of alleles (P = 0.032), but not in the rs801460 (P > 0.05), in groups with and without gynecological pathology, while the distribution of both single nucleotide polymorphism (SNPs) genotypes was similar between these groups (P > 0.05). Statistically significant association was detected between SRA1 rs10463297 polymorphism and gynecological pathology occurrence in both dominant (Pa = 0.023; ORa = 2.638, 95 % CI = 1.145–6.076) and additive (Pa = 0.034; ORa = 2.489, 95 % CI = 1.069–5.794) models of inheritance.

No association was found between SRA1 rs801460 SNP and gynecological pathology development among Ukrainian women with proliferative type of benign breast disease without atypia (P > 0.05).

Conclusions. It was revealed that SRA1 rs10463297 TT carriers had 2.6 times higher risk of gynecological pathology development than C allele carriers and 2.48 times than TC carriers.
