Tailored Axillary Surgery With or Without Axillary Lymph Node Dissection Followed by Radiotherapy in Patients With Clinically Node-positive Breast Cancer (TAXIS/OPBC-03)

RATIONALE: The use of tailored axillary dissection as a tailored procedure will avoid surgical overtreatment by selectively removing the lymph nodes that are affected by the cancer, thereby sparing many women the unnecessary complications of a radical surgery, providing a better quality of life while keeping the same efficacy.

PURPOSE: The phase III trial is evaluating the optimal treatment for breast cancer patients in terms of surgery and radiotherapy.
