Abstract
In order to evaluate the prognostic importance of clinical and histological node information, we made univariate and multivariate analyses of regional lymph node metastases in 223 patients with operable breast cancer who were surgically treated from 1973 to 1985. Clinical axillary node status, histological involvement of the axillary lymph nodes, their anatomical levels and numbers, and histological involvement of the internal mammary lymph nodes were selected as evaluating prognostic factors. The histological presence or absence of axillary node involvement, especially at the distal level, proved to be the most important prognostic factor. However, neither the anatomical level nor the number of histologically involved axillary lymph nodes appeared to be an important prognostic factor. On the other hand, histological involvement of the internal mammary nodes appeared to be an important and independent prognostic factor. Therefore, we concluded that axillary lymph node dissection with a biopsy of the internal mammary nodes would provide more accurate information about the prognosis of patients with operable breast cancer.
