[Prognosis of operable breast cancers in women aged under forty years]

The present study is based on the data of a homogeneous series of 736 women with stage I and II operable breast cancer. The same methodology was used for treatment and follow-up. Eighty-seven patients were under 40 and 649 between 40 and 70 years ols. No statistical difference was noted between the distribution in these 2 groups regarding tumor size, the axillary or internal mammary nodal status or hormonal receptor levels. Small tumors were noted more frequently in the under 40 yr group. Overall survival was the same in both groups, independently of tumor size, axillary nodal status or hormonal receptors. Disease-free survival differed between the 2 groups: local relapse risk was 1.6 times higher for women under 40 yr, in relation to a higher frequency of conservative treatment in this group. No difference was noted for DFS in relation a tumor size, axillary nodal status of hormonal receptors.
