RATIONALE: Removing the sentinel lymph nodes and examining them under a microscope may help plan more effective surgery for breast cancer. It is not yet known if surgery to remove the sentinel lymph nodes is more effective with or without removal of the lymph nodes in the armpit in treating breast cancer.

PURPOSE: Randomized phase III trial to compare the effectiveness of surgery to remove the sentinel lymph nodes with or without removal of lymph nodes in the armpit in treating women who have breast cancer.

Condition Intervention Phase
Breast Cancer Procedure: conventional surgery Procedure: Sentinel node resection followed by node examination Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Randomized, Phase III Clinical Trial to Compare Sentinel Node Resection to Conventional Axillary Dissection in Clinically Node-Negative Breast Cancer Patients

Primary Outcome Measures:
  • Morbidity as measured by arm edema, sensory neuropathy, and arm function - mobility [ Time Frame: Before and after surgery ]
  • Overall Survival as measured by death from any cause. [ Time Frame: Time from surgery to death from any cause ]
  • Disease-free Survival as measured by breast cancer recurrence, any second primary cancer, and death from any cause in patients without a prior event. [ Time Frame: Time from surgery to recurrence, second primary, or death ]

Secondary Outcome Measures:
  • Prognostic value of pathology status of sentinel nodes and nodes obtained from axillary dissection [ Time Frame: At the time of surgery ]
  • Pathology investigation of sentinel nodes [ Time Frame: At time of surgery ]
  • The percentage of technically successful sentinel node resections as measured by the proportion of patients for whom at least one sentinel node is identified. [ Time Frame: At time of surgery ]
  • Sensitivity of the sentinel node to determine presence of nodal metastases. [ Time Frame: At time of surgery ]

Primary Completion Date: September 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Arm I: Conventional axillary dissection

Sentinel node resection immediately followed by axillary dissection.
Experimental: Arm II: Sentinel node resection followed by node examination
Sentinel node resection followed by node examination then axillary dissection if positive sentinel node.
Procedure: Sentinel node resection followed by node examination
