摘要:

目的 探讨乳腺癌患者CYP2D6、SULT1A1基因多态性与他莫昔芬疗效相关性。方法 2018 1 月至 2019 1 月接受他莫昔芬治疗的乳腺癌患者,检测 CYP2D6(100C > T)、SULT1A1 638(G > A)基因 型,分析其与临床病理参数、生存的关系;Kaplan⁃meier生存分析,Log⁃rank检验生存差异。结果 入组203 患者,CYP2D6(100C > T)CC、CT、TT 分别 44 例(21.67%)、117 例(57.64%)、42 例(20.69%)。SULT1A1 638 (G > A)均为 GG 型,无 GA AA 型。CC CT 型患者 2 年总生存率高于 TT 型(P = 0.013)。CC CT 型患 OS TT 型患者延长(P = 0.001)。结论 CYP2D6(100C > T)TT 型他莫昔芬治疗后总生存较 CC、CT 明显下降。SULT1A1 638(G > A)未发现等位基因突变。

Abstract:

Objective To investigate the correlation between CYP2D6,and SULT1A1 gene polymor⁃ phisms and treatment effect of tamoxifen(TAM)in patients with breast cancer. Methods From January 2018 to January 2019,203 patients treated with TAM were included in the study. The genotype of CYP2D6(100C > t and SULT1A1 638(G > A)was detected,and the correlation between genotypes,clinicopathological parameters and the prognosis was analyzed. Kaplan Meier method was used for survival analysis,and log rank test was used to test whether there was survival difference among patients. Results Among 203 cases,44 cases(21.67%),117 cases (57.64%)and 42 cases(20.69%)were CYP2D6(100C > t)CC,CT and TT respectively. Sult1A1 638(G > A was all GG type,and no GA or AA type was found. The 2⁃year OS rate of patients with CC and CT was higher than that of patients with TT(P = 0.001). The OS of CC and CT patients was significantly longer than that of TT patients (P = 0.001). Conclusion The OS of TT patients after TAM treatment is significantly lower than that of CC and CT patients. No allele mutation is found in SULT1A1 638(G > A).
