Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Colon cancer

Colon cancer patients of all stages

Group Type EXPERIMENTAL

Sentinel lymph node procedure

Intervention Type 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.

Bone marrow aspiration

Intervention Type PROCEDURE

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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

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
Eligible Sex
