Abstract: Objective：To evaluate the feasibility and tumor safety of ARM in SLNB or ALND surgery，and to provide reference for determining its accurate indication.Methods：ARM lymph nodes were  imaged with 2 ml indocyanine green solution and sentinel lymph nodes were imaged with methylene blue solution 2ml with 5mg/ml concentration.Axillary lymph node dissection was performed in all patients.Results：Among 117 patients，94 patients were ≤ N1 stage，accounting for 80.4%.ARM lymph nodes were detected in 100 patients with a total detection rate of 85.5%，and in 90 patients with stage ≤ N1，the detection rate was 96%.ARMSLN overlapping patients were detected in 3 patients，including 2 patients with stage N2 and 1 patient with stage N3，and 9 patients with ARM metastasis（7.7%）.Conclusion：ARM operation is feasible and relatively safe for breast cancer patients with axillary stage ≤ n 1，and can be popularized.The case data of patients with stage ≥ N2 are few，so more studies are needed to subdivide them to find out the suitable indications for ARM operation，while ARM operation is not recommended for patients with neoadjuvant chemotherapy.
