Lymphatic Mapping and Sentinel Lymph Node Biopsy in the Treatment of Colorectal Cancer: A Feasibility Study
OBJECTIVES: I. Determine the feasibility of lymphatic mapping and sentinel lymph node biopsy
in patients with stage I, II, or III colorectal cancer. II. Evaluate technetium Tc 99m
sulfur colloid as a mapping agent in this patient population. III. Identify patients with
histologically negative nodes but have positive nodes on further detailed examination.
OUTLINE: Patients undergo preoperative endoscopy with injection of technetium Tc 99m sulfur
colloid around tumor followed by celiotomy and intraabdominal exploration. At 30 minutes
following injection, patients undergo lymphatic mapping with a gamma probe and biopsy of the
sentinel lymph node(s). Following biopsy and mapping, patients undergo resection of primary
tumor. Patients are followed postoperatively, every 4-6 months for 2 years, every 6 months
for 1 year, and then annually thereafter.
PROJECTED ACCRUAL: A total of 10 patients will be accrued for this study within 2 years.
