简要总结
RATIONALE: Diagnostic procedures, such as lymph node mapping and biopsy, may improve the ability to detect the extent of colorectal cancer.
PURPOSE: Diagnostic trial to study the feasibility of lymph node mapping and sentinel lymph node biopsy in patients who have stage I, stage II, or stage III colorectal cancer.
详细描述
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.
