Lymphatic mapping for sentinel node identification


ABSTRACT: Primary objectives: The main objective of this study is to determine whether the first (sentinel) lymph nodes in the drainage pathway of a colonic tumour can be detected at the time of surgery using a new technique. The detection method is to inject a fluorescent dye (indocyanine green) into the colon adjacent to the tumour. The dye will then be seen as it fluoresces in the light from the near infrared spectrum that can be used at the time of the laparoscopic (keyhole) surgery. An endoscope is placed in the colon (colonoscopy) during surgery and the tracer fluorescent agent is injected around the tumour. The mesentery in which the lymph nodes draining the tumour are located will then be examined by laparoscopy and it is expected that fluorescence will be identified within approximately 5 minutes of the injection. The first lymph node or nodes that take up the fluorescent dye will then be marked by placing a clip or a stitch by them. After the surgery has been completed and colon removed, all lymph nodes w Primary endpoints: To establish whether it is possible to identify the first order draining mesocolic lymph nodes (sentinel lymph node(s) (SLNs) in patients with suspected T1 and T2 colonic cancer, using ICG, a fluorescent mapping agent, and a laparoscopic near infrared imaging (NIR) system.
