Green dye to guide early cancer removal
Treatments studied
Part of Cancer, Digestive system clinical trials.
This trial tests whether a special dye (indocyanine green) given through a vein can help doctors see the exact edges and depth of early-stage esophageal or stomach cancer during a minimally invasive procedure to remove it. If you are scheduled for this procedure, the dye may help the surgeon remove the cancer more precisely.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have a very early stage (superficial) cancer in the esophagus or stomach.
- You are 18 years or older.
- You are scheduled for a procedure called endoscopic submucosal dissection (ESD) at the University Medical Center Groningen.
- You are not allergic to the dye indocyanine green (ICG), iodine, shellfish, or clams.
- You do not have severe kidney disease, severe liver disease, or an overactive thyroid.
- You are not pregnant or breastfeeding.

This trial tests if a green dye helps surgeons see and remove lymph nodes more clearly during 3D laparoscopic stomach cancer surgery. The goal is to confirm the dye's safety and benefit for patients undergoing this procedure.
This study tests whether using a green dye called indocyanine green during minimally invasive esophageal cancer surgery can help the surgeon see blood flow better and improve the healing of the new connection between the esophagus and stomach. It may reduce the risk of leaks after surgery.
This trial tests whether a special green dye (indocyanine green) injected during minimally invasive stomach cancer surgery helps doctors remove more lymph nodes, which may improve treatment. It is for people with stomach adenocarcinoma that has not spread to distant organs.
This trial tests whether a green dye called indocyanine green can help surgeons find and remove more lymph nodes during laparoscopic surgery for advanced stomach cancer. It may improve the chances of removing all cancer.
This trial studies whether a fluorescent dye (a “tracer”) can help surgeons find the right area during laparoscopic distal (lower-part) stomach removal for early stomach cancer. It may improve how completely the cancer is removed while keeping surgery minimally invasive.
This trial tests if a special dye called indocyanine green can help surgeons find sentinel lymph nodes during surgery for esophageal cancer. It may help doctors know which lymph nodes to remove for better staging.
