Clinical Trial Title
ACOSOG Z0011: A Randomized Trial of Axillary Node Dissection in Women With Clinical T1-2 N0-1 M0 Breast Cancer Who Have a Positive Sentinel Node
Trial Summary and Conditions
RATIONALE: Surgery to remove lymph nodes in the armpit may remove cancer cells that have spread from tumors in the breast. PURPOSE: Randomized phase III trial to determine the effectiveness of removing lymph nodes in the armpit in treating women who have stage I or stage IIA breast cancer.
Control and experimental arm data files include data on efficacy, demographics, etc. See the data dictionary provided for more details.
OBJECTIVES: Primary objectives: Long term: To assess whether overall survival for patients randomized to Arm 2 (no immediate ALND) is essentially equivalent to (or better than) than that for patients assigned to Arm 1 (completion ALND). Short term: To quantify and compare the surgical morbidities associated with SLND plus ALND versus SLND alone.
Overall survival Disease-free survival
