Abstract

Between December 1983 and December 1989, twenty-five breast carcinoma patients were treated with surgical resection and postoperative radiotherapy at Inje University Seoul Paik Hospital. Twenty-three of 25 were evaluable and there were 7 patients with stage Ⅱ, 14 patients with stage Ⅲ, and 2 patients with stage Ⅳ. Twenty-one patients were treated with modified radical mastectomy and the remained 2 patients with simple mastectomy. The follow-up period ranged from 2 to 8 years. The local control rate was 83c13 for the entire group. The local control rates for each stage were 100%(6/6) for stage Ⅱ, 73%(l1/15) for stage Ⅲ, and 100%(2/2) for stageⅣ. The number of metastatic axillary nodes was a good predictor of locoregional cotrol. It was 100% for the patients with 0-3 metastatic nodes and 72% for more than 4 nodes, respectively. The 5-year overall survival rate for the entire group was 59%, and the disease-free survival rate was 32%. The 5-year survival rates for each stage Ⅱ, Ⅲ and Ⅳ was 83%, 59% and 50%, respectively. The distant metastasis occurred in 10 out of 23 patients and the most common site was bone. The results indicate that postoperative radiotherapy continues to play an important role in the primary mangement of the high-risk breast cancer patients.
