Abstract Objective To explore the necessity, feasibility and efficacy of lymph node dissection through pectoralis muscle approach in Auchincloss operation of breast cancer. Methods From May 2008 to June 2013, clinical and follow-up data of 63 patients with breast cancer who underwent Auchincloss operation plus thoracic muscle approach lymph node dissection in the Affiliated Hospital of West Anhui Health Vocational College were collected, and the LevelⅢ group of lymph node metastasis and risk factors were statistically analyzed. Results Breast cancer patients had adequate surgical exposure and satisfactory lymph node dissection, LevelⅢ group of lymph node metastasis rate was 27.0%. Group LevelⅢ cancer lymph node metastasis was related to tumor size, clinical stage, axillary lymph node status, Her-2 in the cancer tissue and PDCD4 expression (all P < 0.05). Large tumors, staging, axillary lymph node positive rate, its Her-2 expression in cancer tissue and lack of PDCD4 expression were the high risk factors of the LevelⅢ group lymph node metastasis. No serious complications were found in the postoperative follow-up, and the 5-year survival rate was 87.3%. Conclusion To have LevelⅢ group factors of breast cancer patients at high risk of lymph node metastasis Auchincloss surgery, and chest into the way lymph node cleaning is necessary and feasible, with curative effect affirmation.
