Surgery to Remove Sentinel Lymph Nodes With or Without Removing Lymph Nodes in the Armpit in Treating Women With Breast Cancer
Basic Trial Information
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.
Further Study Information
Objectives of quality of life questionnaire in sentinel node-negative patients:
OUTLINE: This is a randomized study. Patients are stratified according to the surgical treatment plan (lumpectomy vs mastectomy), age (49 and under vs 50 and over), and clinical tumor size (no greater than 2.0 cm vs 2.1-4.0 cm vs at least 4.1 cm). Patients are randomized to one of two surgery arms.
All patients receive technetium (Tc 99m) sulfur colloid injected into normal breast tissue within 1 cm of the primary tumor or biopsy cavity and an intradermal injection of technetium (Tc 99m) sulfur colloid, approximately 0.5-8 hours before surgery. Patients also receive an injection of isosulfan blue dye around the tumor or biopsy cavity after a hot spot is identified with a gamma detector. If a hot spot is not identified, the blue dye is injected after a saline bolus injection.
Patients with positive sentinel nodes undergo axillary dissection after sentinel node resection.
Patients with cytologically negative sentinel nodes do not undergo axillary dissection.
Patients with cytologically negative but histologically positive sentinel nodes return to surgery for axillary dissection.
Patients with histologically positive sentinel nodes and those in whom the sentinel node is not identified undergo axillary dissection after sentinel node resection.
Patients with pathologically positive, nonaxillary sentinel nodes undergo axillary dissection after sentinel node resection.
Patients with evidence of tumor remaining after surgery undergo a total mastectomy.
Quality of life is assessed at baseline, at weeks 1-3, and then every 6 months for 3 years or until recurrence.
Patients are followed at 1 and 3 weeks, every 6 months for 3 years, and then annually thereafter.
PROJECTED ACCRUAL: Approximately 5,400 patients will be accrued for this study within 4 years.
