[Treatment result of radiation therapy alone in carcinoma of the breast--analysis of 116 cases from 19 hospitals].
In order to analyze the radiation effect for the breast cancer 116 patients without distant metastasis were collected from 19 large hospitals in Japan. The cumulative five and ten year survival rates were 85%, 80% in stage I (20 cases), 75%, 61% in stage II (41 cases) and 21%, 9% in stage III (55 cases), respectively. In stage I-II, the five year actuarial survival rate of the papillotubular type is better than that of the scirrhous type. In stage III, more than 70 Gy for the primary breast tumor and more than 50 Gy for the regional lymph node regions must be given, to obtain the good result. On the other hand, no correlation was observed between the given dose and the survival rate in stage I-II, due to the influence of the distant metastasis.
