Since October 1976, the treatment policy in our Radiotherapy Center for Stage I carcinoma of the breast has been excision of the tumor mass, when it was cosmetically suitable, followed by irradiation to the breast and peripheral lymphatics. Eighty-three patients were admitted between October 1976 and March 1980. They underwent local excision of the tumor and then received 5000 rad in 5 weeks to the breast, supraclavicular, axillary and internal mammary chain lymph nodes. Each field was treated every day. A boost was then given to the scar, bringing the dose up to 6500 rad, calculated at maximum tumor depth, depending upon the size of the tumor prior to surgery. Cosmetic results were quite good, and the local control rate at 54 months is 98%. The survival with no evidence of disease (NED) at 54 months (acturarial) is 83%. There have been 10 failures: 8 distant, 1 local (in axilla, controlled by surgery, actually NED), and 1 local and distant (scar and brain). Both failures were found with 12 months after treatment, and 8/10 of the failures within 24 months. Twenty-one out of 83 patients have had complications (25.3%); of these, 28.8% were surgical and the remainder resulted from radiotherapy after surgery, either from radiotherapy alone or from combination of treatments. Of the total of 21 complications 18 were mild and 3 were serious. Of those 3 serious complications (3.6%), 2 were a result of radiotherapy, and one because an ill-advised axillary dissection prior to radiotherapy gave a negative axilla and a serious arm edema and painful shoulder. This was the worst complication in the total of 83 patients. These results compare favorably with the results achieved in the same Hospital with radical surgery as far as local tumor control and survival with no evidence of disease (NED) is concerned.
