RATIONALE: Diagnostic procedures, such as lymph node mapping during surgery and sentinel lymph node biopsy, may help doctors find micrometastases and predict cancer recurrence.
PURPOSE: This phase II trial is studying how well lymph node mapping during surgery together with sentinel lymph node analysis and blood testing work in detecting and predicting early micrometastases in patients with colorectal cancer.

Phase II |
Study Type: | Interventional |
Study Design: | Diagnostic |
Official Title: | Ultrastaging of Early Cancer of the Large Bowel Using Intraoperative Lymphatic Mapping, Sentinel Node Analysis and Blood Testing |
Estimated Enrollment: | 225 |
Study Start Date: | March 2004 |
Estimated Primary Completion Date: | November 2007 (Final data collection date for primary outcome measure) |
OBJECTIVES:
OUTLINE: Patients receive isosulfan blue subserosally around the primary tumor for sentinel lymph node (SLN) identification and SLN(s) are marked. Patients undergo a standard colon resection as planned to include the SLN(s) and regional lymph nodes.
Lymph nodes removed during surgery are analyzed within 30 days after surgery. Routine pathologic analysis (H&E) are performed on all lymph nodes (SLN and non-SLN) removed. Immunohistochemical (IHC) staining for cytokeratin antibodies AE-1/AE-3 or MAK-6 are performed on all lymph nodes negative by H&E. Multimarker PCR (MM PCR) are performed on all SLNs. Blood samples are collected at baseline and then periodically for 4 years for MM PCR to detect circulating tumor cells and standard tumor markers (e.g., CEA).
After surgery, patients are followed every 6 months for 4 years.
