E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
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 |

E.2.2 | Secondary objectives of the trial |
• To assess the extent to which that the tumour-bearing status of SLN(s) identified corresponds with lymph node status as assessed by standard methods (pathological examination of excised nodes using H&E and immunohistochemistry) • To estimate the proportion of patients with aberrant nodal drainage. i.e. the proportion with SLN(s) lying outside the standard resection field |

E.5 End points |
E.5.1 | Primary end point(s) |
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. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
As it is a feasibility study and we are recruiting a small number of patients, evaluation of data will not commence untill the last patient has undergone surgery. |
|
E.5.2 | Secondary end point(s) |
• Sensitivity and specificity of tumour-bearing status of SLN(s) as a measure of lymph node status when assessed by standard techniques. • Frequency and tumour-bearing status of aberrant SLN(s) |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
As it is a feasibility study and we are recruiting a small number of patients, evaluation of data will not commence untill the last patient has undergone surgery. |
