The study is a feasibility and validation study of the sentinel lymph node (SLN) procedure in all stages of colon cancer. If the SLN can be reliably identified, it could be submitted to a more accurate histopathological examination (multiple sections, special staining). The detection of micrometastases in the SLN (occult stage III, upstaging) is possible. Patients with micrometastases should be considered at higher risk.

Additionally, a search for occult metastatic tumor cells in the bone marrow is performed.

Primary Outcome Measures:
  • To assess the extent of upstaging due to the SLN procedure for colon cancer. [ Time Frame: 1 month ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To evaluate the accuracy of the SLN procedure for colon cancer. To identify factors influencing the success of the procedure. To correlate SLN results with the presence of colon cancer cell in bone marrow aspirates. To assess OS and DFS. [ Time Frame: 1 month, 3 and 5 years after surgery ] [ Designated as safety issue: No ]

Estimated Enrollment: 200
Study Start Date: May 2000
Estimated Study Completion Date: December 2011
Primary Completion Date: January 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Colon cancer
Colon cancer patients of all stages
Procedure: Sentinel lymph node procedure
After careful mobilization of the affected colon segment, isosulfan blue 1% is injected in vivo into the subserosa circumferentially around the tumor. Lymph nodes in the mesentery staining blue within the first minutes are marked as SLN. The procedure is followed by a resection of the affected colon segment with standard lymphadenectomy.
Other Name: Lymphazurin 1%, Ben Venue Labs Inc., Bedford OH
Procedure: Bone marrow aspiration
Prior to surgery, bone marrow is aspirated from both iliac crests. Bone marrow aspirates are analyzed for the presence of occult metastatic colon cancer cells.


Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Colon cancer at any stage diagnosed histologically or high degree of suspicion for colon cancer at endoscopy, which cannot be confirmed with certainty in the biopsy. The diagnosis of cancer must be certain in the definitive histology.
  • Possibility of transabdominal injection of the dye (cancers below the peritoneal reflection in which the injection of dye must be carried out through rectoscopy, are therefore excluded).
  • Patient's informed consent

Exclusion Criteria:

  • Prior intrabdominal tumor surgery
  • Other preexisting malignancies
  • Hypersensitivity/allergy to dye (isosulfan blue)
  • Pregnancy
  • Breast-feeding
  • No patient's informed consent
