摘要: 目的 探索乳腺癌术后应用芳香化酶抑制剂(AIs)引起的骨代谢异常与ERα基因rs9340799、rs2234693位点单核苷酸多态性(SNPs)之间的相关性。方法 将2015年10月—2017年4月期间在我院门诊及住院治疗的116名乳腺癌术后接受AIs治疗(≤2年)的患者行ERα基因rs9340799、rs2234693位点测序并比较各基因亚型的腰椎、股骨的骨密度(BMD)值以及T值之间的关系。结果 ERα基因rs9340799位点3个亚型(A/A、A/G、G/G)患者的腰椎BMD值比较具有统计学差异(P<0.05)。A/A、A/G基因型患者的腰椎BMD值均高于G/G基因型患者(P<0.05);ERα基因rs2234693位点的3个基因亚型(T/T、C/T、C/C)患者的腰椎BMD值比较具有统计学差异(P<0.05),T/T、C/T基因型患者的腰椎BMD均高于C/C基因型患者(P<0.05)。但两位点各基因亚型患者的股骨BMD值、腰椎T值、股骨T值组间比较均无统计学差异(P>0.05)。结论 芳香化酶抑制剂相关骨丢失(AIBL)的发生可能与ERα基因表型相关。ERα基因rs9340799与rs2234693位点中,C、G等位基因可能是发生AIBL的易感型基因。

Abstract: Objective The aim of this study was to explore the correlation between postoperative aromatase inhibitor(AIs)- based bone metabolism and ERα gene rs9340799,rs2234693 single nucleotide polymorphisms(SNPs)in breast cancer. Methods One hundred and sixty-six breast cancer patients who underwent AIs treatment(≤2 years)were enrolled and hospitalized in our hospital from October 2015 to April 2017.The ERα gene rs9340799 and rs2234693 sites were sequenced and compared subtype of lumbar spine and femur,bone mineral density BMD value and the relationship between BMD value and T value. Results The BMD of lumbar spine in patients with ERα gene rs9340799 was significantly different when compared to those of A/A,A/G and G/G(P<0.01).The BMD of lumbar spine in patients with A/A and A/G genotypes were significantly higher than those in G/G genotypes(P<0.05).The BMD of lumbar spine in patients with ERα gene rs2234693 was significantly different when compared to those of T/T,T/C and C/C(P<0.01).The BMD of lumbar spine in patients with T/T and C/T genotypes were significantly higher than those in C/C genotypes(P<0.05).However,there was no difference in femoral BMD,lumbar spine,and femur T between the 2 subtypes of patients with genotypes(P>0.05). Conclusion Aromatase inhibitor-related bone loss(AIBL)may be related to ERα gene phenotype.In ERα gene rs9340799 and rs2234693 loci,C and G alleles may be susceptible genes for aromatase inhibitor-related bone loss(AIBL).
