Abstract:
:In order to establish a therapeutic approach for primary breast cancer of medial and central origin, we reviewed 183 patients who had been treated by one of the following three modalities at the Second Department of Surgery, Osaka University Medical School between January, 1965 and December, 1980. Group A (n = 70): standard radical mastectomy alone; Group B (n = 34): standard radical mastectomy followed by postoperative irradiation to the parasternal and supraclavicular regions, and; Group C (n = 62): extended radical mastectomy that included removal of the parasternal lymph nodes. The background factors of the three groups were not significantly different. The overall survival five and ten years following surgery in the three groups were 91 percent and 79 percent in group A, 82 percent and 67 percent in group B, and 82 percent and 70 percent in group C, respectively, showing no significant difference in overall survival among the three groups. When the patients were classified according to the extent of axillary lymph node involvement, there was no difference in survival among the three treatments in patients who had less than three lymph node metastases in the axilla. However, treatment of the parasternal lymph nodes improved survival in the patients who had more than four lymph node metastases in the axilla. Parasternal lymph node involvement definitely worsened the prognosis, showing it to be a good prognostic factor. Thus, extended radical mastectomy should be considered for patients with breast cancer of medial or central location, when extended axillary lymph node involvement is found.
