Bilateral breast carcinoma: 28 years' experience.
From 1959 to 1987, a total of 1,182 histologically proven breast cancer patients were followed. Of these, 48 (4.06%) with bilateral breast carcinoma were reviewed. Eight patients (0.68%) had simultaneous breast carcinomas and the remaining 40 (3.38%) had nonsimultaneous breast carcinomas. The period between the development of the first and second primary carcinoma ranged from 17 to 200 months (mean, 86 months). The second primary carcinoma was found symmetrically located with the first primary carcinoma in only 34.5% of the cases. No significant differences were observed between the bilateral carcinoma patients and the unilateral carcinoma patients with respect to pregnancy, delivery, family history, and the size and localization of the carcinomas. Axillary metastasis was seen in a higher percentage of the second primary carcinomas (48% versus 37.5%). It was observed that the shorter the time interval between the presentation of the carcinomas, the shorter the survival.
