Spots Global Cancer Trial Database for Lymph Node Mapping Via Flourescent Dye in Colon Cancer

Study Description

Brief Summary: The aim of the study is to evaluate whether lymph nodes draining the region of the carcinoma are located only inside the lines of standard resection or in some percentages are located outside as well. The visualized nodes draining the region of the carcinoma will be correlated to location, fluorescent yes/no and nodal positive/negative. The draining lymph nodes will be visualized using the fluorescent dye indocyanine green.

The draining lymph nodes will be visualized using the fluorescent dye indocyanine green.

Detailed Description: Participants with a diagnosed (andeno)carcinoma of the ascending, transverse, descending and sigmoid colon will be included. Preoperatively the participants will receive an indocyanine green(ICG) injection at four points around the tumour endoscopically. The ICG marking will take place one to five days prior to surgery. In the draining lymph nodes of the specific region the ICG will accumulate and thus visible via fluorescence-camera during the surgery. Intraoperatively, the precise locations of all fluorescent nodes will be documented photographically. A standard resection and lymph node dissection will be conducted, potential fluorescent nodes outside the standard resection lines will additionally be resected. The fresh specimen will then be measured, the fluorescent nodes marked and after the pathologic examination the nodes will be correlated to location, fluorescent yes/no and nodal positive/negative. The aim ist not the visualization of the Sentinel node or the directly draining lymphatic vessel but all the nodes draining the peritumorous region at the point of surgery.
