title: The significance of regional lymph node dissection in the surgical management of breast cancer.
abstract: The results of an analysis done on the regional lymph node metastases of 300 patients with operable breast cancer, who were treated in the Department of Surgery (II), Kanazawa University Hospital from 1973 to early 1988 are reported herein. It was found that the metastases of the axillary and internal mammary lymph nodes were closely related to the survival of patients, but they were hardly diagnosed before the operation. Only the dissection of these lymph nodes proved useful for providing the prognostic information. Moreover, in a retrospective study comparing the en bloc extended radical mastectomy versus the other types of mastectomy, the extended radical mastectomy was seen to greatly improve the survival of patients with 3 or less than 3 metastatic axillary lymph nodes. Thus, the extended radical mastectomy provides the maximum diagnostic and prognostic information, and gives the best chance of loco-regional control of the disease. The anterior chest deformity created by the extended radical mastectomy, however, should be avoided in those patients without internal mammary involvement. We therefore propose the modified extended mastectomy as a staging operation.
