摘要
Background: Axillary lymph node dissection is an important procedure in the surgical treatment of breast cancer. Axillary lymph node dissection is still performed in over half of breast cancer patients having histologically negative nodes, regardless of the morbidity in terms of axillary pain, numbness and lymphedema. The first regional lymph nodes draining a primary tumor are the sentinel lymph nodes. Sentinel node biopsy is a promising surgical technique for predicting histological findings in the remaining axillary lymph nodes, especially in patients with clinically node-negative breast cancer, and a worldwide feasibility study is currently in progress. Methods: Intraoperative lymphatic mapping and sentinel node biopsy were performed in the axilla by subcutaneous injection of blue dye (indigocarmine) in 88 cases of stage O-IIIB breast cancer. Sentinel lymph nodes were identified by detecting blue-staining lymph nodes or dye-filled lymphatic tracts after total or partial mastectomy. Finally, axillary lymph node dissection was performed up to Levels I and II or more. Results: Sentinel lymph nodes were successfully identified in 65 of the 88 cases (74%). In the final histological examination, the sentinel lymph nodes in 40 cases were negative, including four cases with non-sentinel-node-positive breast cancer (specificity, 100%; sensitivity, 86%). In nine (31%) of the 29 cases with histologically node-positive breast cancer, the sentinel lymph nodes were the only lymph nodes affected. Axillary lymph node status was accurately predicted in 61 (94%) of the 65 cases. Conclusions: Although it was the initial experience at the National Cancer Center Hospital East, sentinel node biopsy proved feasible and successful. This method may be a reasonable alternative to the standard axillary lymph node dissection in patients with early breast cancer.
