Abstract:Objective To study the effect of endocrine therapy on hormone receptor positive breast cancer and its relationship with ESR1 gene locus (rs2077647 and rs3798759). Methods Eighty-six patients with hormone receptor positive breast cancer admitted to the Fifth People′s Hospital of Changshu City in Jiangsu Province from January 2014 to December 2018 were selected as study objects. All patients were treated with endocrine therapy and ESR1 single nucleotide polymorphisms (rs2077647 and rs3798759) were detected. The short-term efficacy of endocrine therapy was analyzed and its relationship with ESR1 single nucleotide polymorphisms was observed. Results Forty five patients of 86 patients with complete remission, partial remission and stable disease after endocrine therapy were included in ETR group, 41 patients with disease progression were classified into ETNR group. The proportion of genotype CC at rs2077647 in ETR group was significantly higher than that in ETNR group (P < 0.05), the proportion of TT genotype of rs3798759 was significantly lower than that of ETNR group (P < 0.05), and the proportion of TG genotype was significantly higher than that of ETNR group (P < 0.05). The proportion of allele C at rs2077647 in ETR group was significantly higher than that in ETNR group (P < 0.05), and the proportion of allele G at rs3798759 was significantly higher than that in ETNR group (P < 0.05). ESR1 gene polymorphism was an independent factor affecting the effect of endocrine therapy (P < 0.05). Conclusion The effect of endocrine therapy on hormone receptor-positive breast cancer is closely related to ESR1 single nucleotide polymorphisms (rs2077647 and rs3798759).
