摘要：

Objective. To evaluate if variants in the genes CYP1A1 (T3801C and A4889G), CYP1B1 (G119T), GSTM1 (indel) and GSTT1 (indel) are associated with breast cancer (BC) among Mexican women. Materials and methods. 952 incident cases with histologically confirmed BC were matched by age(+/- 5 years) and zone of residence with 998 healthy population controls. Genetic variants in genes CYP1A1, CYP1B1, GSTM1 and GSTT1were genotyped by allelic discrimination and multiplex PCR. In a subsample of women, 105 markers for ancestry were determined. Results. An increased BC risk, independent of other BC risk factors, was observed among carriers of CYP1B1 G119T genotype (T/T vs. G/G: OR=1.9; 95%CI 1.4-2.5). Conclusion. Our results support the existence of genetic susceptibility for BC conferred by CYP1B1 G119T variant among Mexican women.
