Minimally INvasive Colon Cancer Surgery Through IMmunomics and Optical Mapping of the Sentinel Lymph Node.

Summary

The project investigates the feasibility of laparoscopic fluorescent imaging for the intraoperative detection of the sentinel lymph node (SLN) in colon cancer patients. In addition, the topology of immunological and microenvironmental changes in normal and invaded lymph nodes (LN's) will be correlated to the LN location (anatomical mapping).
