Diagnostic Study to Identify Sentinel Lymph Nodes in Women With Stage I or Stage II Breast Cancer
Recruitment status was Active, not recruiting
RATIONALE: Diagnostic procedures, such as blue dye or imaging to identify sentinel lymph nodes, may improve the ability to detect the extent of disease and help plan effective surgery for removing breast tumors.
PURPOSE: Diagnostic trial to study the effectiveness of blue dye and an imaging procedure to identify the sentinel lymph node under the arm in women with stage I or stage II breast cancer.
Drug: patent blue V dye
Procedure: radionuclide imaging
Procedure: sentinel lymph node biopsy
Radiation: technetium Tc 99m sulfur colloid
|Study Design:||Primary Purpose: Diagnostic|
|Official Title:||Diagnostic Study of Patent Blue V Dye to Identify Sentinel Lymph Nodes in Patients With Stage I or IIA Breast Cancer|
|Study Start Date:||September 1997|
OBJECTIVES: I. Determine whether the concept of a sentinel lymph node within the axillary nodal basin is valid in staging breast cancer. II. Determine the sensitivity of combined methods of identification of sentinel lymph nodes by patent blue V dye and gamma probe detection in these women.
OUTLINE: Patients receive patent blue V dye injection peritumorally prior to surgery. Preoperative lymphoscintigraphy is performed using technetium Tc 99 sulfur rhenium colloid injected around the tumor associated with intraoperative gamma probe detection. Nonpalpable tumors receive a localized injection using stereotactic injection techniques. Patients then undergo standard axillary (level I and II) lymph node dissection.
PROJECTED ACCRUAL: A total of 200 patients will be accrued for this study within 1 year.
