Abstract |
We report 13 cases of breast carcinoma in patients treated with neuroleptics ( prolactin-releasing drugs). Twelve of the patients were female and one was male. Nine patients had unicentric carcinoma, one had multicentric tumors arising synchronously, and three had bilateral tumors (synchronous in one case and metachronous in two cases). Thirteen tumors in ten patients were invasive ductal carcinomas, two tumors in one patient were mucinous carcinomas, and the two other patients had lipid-secreting carcinomas. Immunohistochemical staining showed alpha-lactalbumin (alpha-LA) in the lipid-secreting carcinomas at sites exhibiting active lipid secretion. A precise cause-effect relationship is difficult to elucidate, since the patients ranged in age from 40 to 64 years (mean: 51 years) when cancer was first diagnosed. However, the relatively high incidence of multiple tumors and the production of lipid and alpha-LA by the cancer cells were unusual features suggesting an association with neuroleptic therapy.
