Abstract: To identify the clinical applications and significance of ter-group axillary lymph node dissection using Kodama mode in patients with breast cancer. Methods: The subjects of the present study were 322 patients with clinically apparent axillary lymph nodes. Among them, 154 were operated by Kodama mode and 168 were operated by normal Auchinclos axillary lymph node dissection. The regional lymph nodes were removed for pathological study. Follow-up studies were conducted to determine the disease-free survival of the patients. Results: The two groups had no statistical significance in surgical duration, but had statistical significance in axillary lymph nodes and ter-group axillary lymph nodes. The five-year disease-free survival of patients operated via Kodama mode was 58.9%, whereas that of the other group was 51.1%. The difference was not statistically significant. Conclusion: The procedure has specific clinical value for patients with clinically apparent axillary lymph nodes. Operation by Kodama mode enables easy dissection of the ter-group axillary lymph nodes.
