The Prognosis Effect of Indocyanine Green (ICG) Fluorescence Guided Surgery on Disease-free Survival (DFS) of Stage III Colorectal Cancer

A Single Center Randomized Controlled Study of the Prognosis After Indocyanine Green Fluorescence-guided Radical Surgery in Colorectal Cancer Patients of Stage III

Previous studies of Indocyanine green (ICG) in colorectal surgery have focused on lymphatic mapping, lymph node detection, and the number of harvested lymph nodes. However, relatively few studies have evaluated the outcomes of this imaging technology, especially the prognosis following of colorectal cancer resection. The present study assessed the prognosis of stage III colorectal cancer patients following ICG fluorescence-guided surgery as compared to conventional surgery without the use of ICG Fluorescence imaging

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Disease-free survival (DFS) rate	the rate of of no recurrence or metastasis after 3 years from radical surgery	From radical surgery to the end of follow-up ,up to 36 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
the number of harvested lymph nodes	the number of harvested lymph nodes of radical surgery	From radical surgery to the end of perioperative period at 1 month
Postoperative complications	Postoperative complications ICG-related complications, surgery-related complications, and systemic complications. Postoperative complications were graded according to the Clavien-Dindo system	From radical surgery to the end of perioperative period at 1 month
Overall survival rate	the rate of 3 years overall survival after radical surgery	From radical surgery to the end of follow-up ,up to 36 months
