[Effect of administration of hormonal contraceptives on prognostic factors in breast cancer].
Up to now, there are only a few and different results from investigations concerning a possible influence of oral contraceptive use on the prognosis of breast cancer. In this study, data from 195 patients with breast cancer showed no significant differences of histologic types, grading and extent or axillary node involvement between oral contraceptive users and nonusers. The frequency of local recurrencies and metastases as well as the disease-free interval and the short-time survival showed also no significant differences. There was a slight but not significant trend in increasing undifferentiated carcinomas after use of oral contraceptives, but the survival rate of these patients was not different from that of non-users.
