Intraductal "Noninfiltrating" Carcinoma of the Breast

Abstract
• We are reviewing 40 patients with noninvasive intraductal carcinoma of the breast. Multicentricity occurred in 33% of the patients; 10% developed opposite breast cancer of the invasive variety. Twenty-one patients underwent radical mastectomy in which one patient was found to have a positive axillary node. The 19 remaining patients had total mastectomy alone. No recurrence or death attributed to intraductal carcinoma was found in 39 patients available for follow-up.(Arch Surg 111:1063-1067, 1976)
