Summary

Approximately 20-30 % of colon cancer patients who have no metastasis in lymph nodes after definitive colectomy have recurrence with distant metastasis. These recurrences could be due to missed occult tumor cells or micrometastasis. Detailed examination of all lymph nodes is expensive and time consuming. Sentinel lymph node mapping using Indocyanine green dye helps in identifying the lymph nodes which are most likely to harbour metastasis. These sentinel lymph nodes can be subsequently subjected to detailed pathologic examination and immunohistochemistry which increases the likelihood of identifying micrometastasis and occult tumor cells. Patients found to harbour such metastasis can be treated with additional chemotherapy after surgery. The aim of the study is to examine the feasibility of sentinel lymph node mapping using Indocyanine green dye in colon cancer and evaluate the upstaging rate in post-operative colon cancer patients who don't have metastatic lymph nodes on routine histopathology.

PROCEDURE

sentinel lymph node mapping

Through on-table colonoscopy indocyanine green solution will be injected in the submucosa at 2-4 points around the tumor for laparoscopic surgeries. Dye will be injected in the subserosa at 2-4 points for open surgeries. Lymphatic flow from the tumor will be mapped in real time with near-infrared fluorescence imaging scope and sentinel lymph nodes will be identified.
