ABSTRACT
Follow-up studies on 172 patients who had undergone curative surgery for breast cancer, were done. 1) There was no significant difference in the 5-year-survival rate between stage I and stage II, however, this survival rate was lower in stage III. 2) The survival rate of patients with metastasis to fewer than 3 lymph node tended to be higher than in patients with metastatic involvement of 4 or more lymph nodes. 3) Patients with papillo-tubular type cancer had the best prognosis followed by medullo-tubular type and scirrhous type. 4) The operative procedures used made no significant difference on the long-term results, although extended operation for stage II cancer showed better result than typical operation in terms of 10-year-survival. 5) The chemotherapy group showed better results than the radiation-treated group in terms of 5-year-survival.
