A multivariable linear regression adjusted for estrogen exposure, BMI, and bisphosphonate use in the previous two years found no correlations of baseline DXA BMD (g/cm2), T score, or Z score in any of the three sites examined, with various parameters of breast cancer including: tumor size and grade, hormone-receptor status, nodal involvement, and disease stage. The gene discussed is NR4A1; the disease is breast carcinoma.
