[Long term results in 69 breast cancer cases treated by radiation therapy at the Radiation Department of Cancer Institute Hospital from 1947 to 1958].
Histologically proved 69 cases of breast cancer were treated by irradiation without mastectomy after either removal of primary tumor or biopsy only at the Radiation Department of Cancer Institute Hospital, Tokyo from 1947 to 1958. Five or 10 years survival rates obtained by Kaplan-Maier's method were 84.6%, 76.2% for Stage I (13 cases), 81.4%, 76.2% for Stage II (34 cases), 25%, 25% for Stage IIIa (4 cases) and 9.1%, 0% for Stage IIIb (11 cases), respectively. Our results of Stage I and II were neary the same as that of curative operation. Our stage III patients showed poorer survival rates than that of curative operation probably due to technical insufficiency.
