Surgery to Remove Sentinel Lymph Nodes With or Without Removing Lymph Nodes in the Armpit in Treating Women With Breast Cancer - Full Text View

Sponsor:	National Surgical Adjuvant Breast and Bowel Project (NSABP)
Collaborator:	National Cancer Institute (NCI)
Information provided by:	National Surgical Adjuvant Breast and Bowel Project (NSABP)
ClinicalTrials.gov Identifier:	NCT00003830

Purpose

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.

Primary Outcome Measures:

Morbidity as measured by arm edema, sensory neuropathy, and arm function - mobility [ Time Frame: Before and after surgery ] [ Designated as safety issue: No ]
Overall Survival as measured by death from any cause. [ Time Frame: Time from surgery to death from any cause ] [ Designated as safety issue: No ]
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 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Prognostic value of pathology status of sentinel nodes and nodes obtained from axillary dissection [ Time Frame: At the time of surgery ] [ Designated as safety issue: No ]
Pathology investigation of sentinel nodes [ Time Frame: At time of surgery ] [ Designated as safety issue: No ]
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 ] [ Designated as safety issue: No ]
Sensitivity of the sentinel node to determine presence of nodal metastases. [ Time Frame: At time of surgery ] [ Designated as safety issue: No ]

Arms	Assigned Interventions
Arm I: Conventional axillary dissection: Active Comparator Sentinel node resection immediately followed by axillary dissection	Procedure: conventional surgery Sentinel node resection immediately followed by axillary dissection.
Arm II: Sentinel node resection followed by node examination: Experimental Sentinel node resection followed by node examination then axillary dissection if positive sentinel node.	Procedure: Sentinel node resection followed by node examination Sentinel node resection followed by node examination then axillary dissection if positive sentinel node. No axillary dissection for negative sentinel node.
