title: Breast cancer and regional lymph node dissections.
abstract: Regional lymph node metastases were evaluated in 289 patients with operable breast cancer. The metastases of the axillary and internal mammary lymph node were shown to be closely related to the survival of patients, but the status of these nodes was shown to be impossible to estimate before the operation. Thus, axillary and internal mammary node dissections seem to be very important in order to attain an acceptable amount of information for staging of certain breast cancer patients. Due to the radicality of operations including internal mammary node dissection, the use of modified extended mastectomy is proposed as the staging operation. In this manner, the anterior chest deformity created by an extended radical mastectomy can be avoided and the pectoralis major muscle spared in patients without internal mammary lymph node involvement. Also found in this study, was some evidence of the beneficial use of en bloc extended radical mastectomy for the survival of a selected group of patients.
