Bile Duct Cancer


Dr. Belanger has a three-step approach when working with a person with a biliary cancer such as cholangiocarcinoma or gallbladder cancer.

Step one: He frequently orders a test that determines what drugs and natural medicines are best at inducing cell death of the biliary cancer cells found in a person’s blood. He also recommends tumor genetic profiling to determine if there are any actionable mutations that can be treated such IDH and FGFR. He works with a lab called RGCC in Greece. This lab isolates circulating biliary cancer cells from the bloodstream and tests over fifty natural substances and over fifty drugs to determine which have the greatest ability to induce cancer cell death. Dr. Belanger will use this information to construct a plan which will include recommending the best drug regimen on the RGCC test and adding nutritional supplements which may improve the ability of cisplatin and gemcitabine, for example, to induce biliary cancer cell death while reducing the drugs toxicity on healthy cells. In addition, he will use the RGCC test to select two or three nutritional supplements which came up the highest at inducing biliary cancer cell death.

Step two: He orders over five panels at a variety of labs to assess imbalances in the patient’s immune system. In order for cancer to grow and create symptoms and/or appear on a scan, it needs to escape a person’s immune system. Dr. Belanger does extensive tests to determine how and why the biliary cancer cells were not destroyed by a patient’s immune system and he uses this information to select nutritional supplements that correct these imbalances. To determine if these imbalances have been eliminated, he retests the abnormal immune labs to make sure they have been restored to normal. This helps him determine that the patient’s immune cells are now capable of destroying biliary cancer cells in the future. This may also improve the effectiveness of single target immunotherapies such as nivolumab and pembrolizumab because more immune system parameters in addition to PDL1 have been assessed and addressed.

Step three: Dr. Belanger orders a third panel of lab tests from over three separate laboratories to determine what is stimulating the growth and potential spread of the biliary cancer. In order for a tumor to grow beyond a few millimeters it needs an adequate blood supply to provide it with a constant supply of nutrients and oxygen. There are numerous blood vessel stimulators that are commonly produced by biliary cancer cells that can be detected in the blood such as VEGF and interleukin-8. Dr. Belanger measures over ten of these growth factors and prepares a customized blend of nutritional supplements to decrease their levels. After about one month, he remeasures any growth factor that was elevated to help ensure that the cancer is being “starved” and not able to build anymore new blood vessels.


I was referred to Dr Belanger after being diagnosed with an aggressive, rare and "incurable" cancer at a young age. He recommended a specific diet, did bloodwork to monitor cancer growth factors and supplements to get my immune system working again. I had very few side effects from the chemo and was able to be on it 3x longer than most are able to tolerate. I am now off chemo, but continue to see Dr Belanger to keep my immune system healthy.
