Abstract
The urinary ratio 2-hydroxyoestrone/16-hydroxyoestrone (URME), has been proposed in various populations on the world as a risk indicator for breast cancer (BC), however in the Mexican population has never been determined.
Objective: To determine URME Mexican women and establish its relationship with risk factors for BC.
Material and methods: Cross-sectional study of 142 premenopausal and 42 posmenopausal women. The URME was determined with the kit ESTRAMETTM and was related to risk factors for BC. Correlations and linear regressions were performed.
Results: The median URME was 0.90 (RIQ 0.64-1.18). The body mass index (BMI) and early menarche contribute 5.4% of their variability (F=5.17; p.
