[Bilateral primary breast cancer. An analysis of 64 cases]

Abstract

64 cases of bilateral primary breast cancer were confirmed pathologically and treated in our hospital from 1973 to 1990. There were seven synchronous cases and 57 cases of sequential type. The patients were treated by surgery, radiotherapy and chemotherapy, separately or in combination. 2-, 5-, and 10-year survival rate were 81%, 46.7% and 20%, respectively. The incidence, diagnosis, clinical features, and therapeutic indications for bilateral breast cancer were discussed.
