Breast cancer: reliability of mammographic appearance as a predictor of hormone receptor status

The association of mammographic appearance with hormone receptor status was investigated in 397 patients with primary breast cancers. The mammographic appearance was classified as type 1, spiculated (n = 159); type 2, structural changes (density) (n = 102); type 3, calcifications (n = 30); type 4, circumscribed opacity (n = 65); and type 5, not visible on mammogram (n = 41). Univariate analysis showed a significant association with estrogen receptor (ER) status for age (less than 50 vs greater than or equal to 50 years), tumor TNM category (those in category 1 vs those in higher categories), and mammographic appearance; with progesterone receptor status, the association was significant only for age. Multivariate analysis adjusted for potential confounders confirmed a significant association between ER status and mammographic appearance (ER status was more likely with type 1 than with the other mammographic types), but the strength of the association was limited. The mammographic appearance of breast cancer is not a reliable method to predict hormone receptor status for clinical purposes.
