Summary
Study start date: September 1, 1997
Actual date on which the first participant was enrolled.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.
