title: A ten year study of medullary carcinoma of the breast.
abstract: In this large series of patients treated for medullary carcinoma of the breast by radical mastectomy, the over-all five year survival rate was 63.7 per cent and the ten year survival rate, 49.5 per cent. Although survival was adversely affected by axillary lymph node involvement, there was an equal incidence of such involvement, there was an equal incidence of such involvement in tumors less than 4 centimeters compared with those greater than 4 centimeters in size; however, patients with tumors greater than 4 centimeters in size fared poorer categorically than did those with smaller lesions. Women in the premenopausal period had one-third of the cancers and had a significantly better survival rate than did those in the postmenopausal period, despite a similar incidence of axillary lymph node involvement. Medullary carcinoma is among the small group of malignant tumors of the breast that have distinctly better five and ten year survival rates than other more common varieties.
