[Cancer of the breast in patients having prostatic cancer treated with estrogens. Report of three cases (author's transl)].
The authors, after personally observing three cases, review the literature on breast cancers in patients with prostatic cancer treated by estrogens. The authors' three cases are all metastatic breast cancers, and one has also a renal cancer. These three cases are added to the 22 reported in the literature which include 13 metastatic cancers, 6 primary breast cancers, and 3 cancers of unspecified nature. The seriousness of these breast involvements is obvious when they are a manifestation of tumor dissemination. The authors discuss the possible responsibility of the estrogen therapy in the development of the breast cancer. The downhill course and the appearance of breast cancer with generalized dissemination evinces an important decrease in the patient's immunity which allows metastases and multiple tumors to occur.
