A ten year study of partial mastectomy for carcinoma of the breast.
Since 1970, 334 patients have undergone partial mastectomy, axillary dissection and irradiation for treatment of invasive carcinoma of the breast. The average follow-up period is 59 months. Survival curves were calculated for the entire study group and for patients classified by tumor size, nodal status and stage of disease. The five year over-all survival rate for 334 patients is approximately 87 per cent; the ten year survival rate is approximately 64 per cent. Of the 334 patients, 247 (74 per cent) have been observed for at least two years. Fourteen of these patients (5.7 per cent) have had a recurrence of carcinoma develop within the treated breast.
