[Correlation with mammography and estrogen receptors in breast neoplasms].

Abstract

A comparative study of 71 patients with unilateral primary breast cancer was performed to verify a possible correlation between the mammographic findings of the cancer and the content of hormonal receptor. The Nielsen & Poulsen, and Wolfe classification were employed. Hormonal receptor content was determined using the Taylor method. The estrogen content was found to be high in type 1, intermediate in 2 and 4, and low in 3 and 5. Statistically significant difference in the estrogen receptor content was found between type 1 and others groups. Using the Wolfe classification, the hormonal content was found to be high in P1. Statistically significant difference was found between N1 and P2; N1 and DY. No relationship was found between histologic cancer type and hormonal receptor content. The Nielsen & Poulsen classification seems to be most simple and reproducible method respect of the Wolfe's parenchymal patterns. Mammographic findings could be used in selecting patients for endocrine therapy where no estrogen-receptor assay is available.
