Lymphatic Mapping and Sentinel Lymph Node Biopsy in the Treatment of Colorectal Cancer

Not Applicable

Completed

• Conditions: Colorectal Cancer

• Registration Number: NCT00005640
• Lead Sponsor: H. Lee Moffitt Cancer Center and Research Institute

Brief Summary

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.

Detailed Description

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.
