Objective: Axillary lymph node metastasis (ALNM) is one of the most important prognostic factors in breast cancer. The reasons why tumours are capable to result in axillary metastasis remain unclear. The evaluation risk of ALNM would improve the treatment planning. We study the metastatic breast carcinoma to the lymph node to obtain information about the metastatic risk. Method: We study 65 patients with metastatic breast carcinoma to the lymph node diagnosed preoperatively by needle biopsy. We study the mitotic average (×10 HPF), metastasis size, positive lymph nodes, total lymph node studied, lymph node ratio (nº of positive node/total nodes nº), primary tumour size and grade. Results: All the cases with high mitotic count were associated with macrometastasis. We didn't find any relation between the mitotic rate or the metastatic size with the number of lymph node affected, and the lymph node ratio. Breast carcinomas G1, T1, <6 mitosis/HPF lymph nodes showed 25-50 % of positive lymph nodes. Conclusion: We tried to obtain information from the metastatic breast carcinoma to the lymph node to predict the axillary status. In our cases we couldn't predict the lymph node involvement based in the tumour size, grade, metastatic size, and metastatic mitotic rate. The preoperative study of a breast tumour and their lymph node metastasis don't allow predicting the lymph node status in our series.
