  Purpose

RATIONALE: Surgery to remove lymph nodes in the armpit in patients with sentinel lymph node micrometastases may remove cancer cells that have spread from tumors in the breast. It is not yet known whether surgery to remove the primary tumor is more effective with or without axillary lymph node dissection.

PURPOSE: This randomized phase III trial is studying surgery and axillary lymph node dissection to see how well they work compared to surgery alone in treating women with node-negative breast cancer and sentinel lymph node micrometastases.

Primary Outcome Measures:
  • 5-year Disease-Free Survival [ Time Frame: 5-year estimate reported after a median follow-up of 60 months ] [ Designated as safety issue: No ]
    Estimated percentage of patients alive and disease-free at 5 years from randomization, where disease-free survival is defined as the time from randomization to first evidence of invasive relapse at any site, second primary tumor (contralateral or non-breast) or death.


Secondary Outcome Measures:
  • 5-year Overall Survival [ Time Frame: 5-year estimate reported after a median follow-up of 60 months ] [ Designated as safety issue: No ]
    Estimated percentage of patients alive and disease-free at 5 years from randomization, where overall survival is defined as the time from randomization to death of any cause.

  • Site of Recurrence [ Time Frame: Reported after a median follow-up of 60 months ] [ Designated as safety issue: No ]
    Site of recurrence of breast cancer


Enrollment: 934
Study Start Date: December 2001
Estimated Study Completion Date: December 2021
Primary Completion Date: November 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Axillary Dissection
Patients undergo surgical resection of the primary tumor with axillary lymph node dissection following sentinel lymph node assessment.
Procedure: Axillary lymph node dissection
Axillary lymph node dissection
Experimental: No Axillary Dissection
Patients undergo surgical resection of the primary tumor with no axillary lymph node dissection following sentinel lymph node assessment.
Procedure: No axillary lymph node dissection
Therapeutic conventional surgery

Detailed Description:

OBJECTIVES:

  • Compare disease-free survival of women with clinically node-negative breast cancer with sentinel lymph node micrometastases treated with surgical resection with or without axillary dissection.
  • Compare overall survival of patients treated with these regimens.
  • Assess sites of recurrence, particularly reappearance of disease in the undissected axilla.
  • Assess long-term surgical complications in patients treated with these regimens.

OUTLINE: This is a multicenter study. Patients are stratified according to participating center, menopausal status (pre- vs postmenopausal), and preoperative sentinel node biopsy (yes vs no). Patients are followed every 4 months for 1 year, every 6 months for 4 years, and then annually thereafter.
