Cancell/Cantron/Protocel (PDQ®): Complementary and alternative medicine - Health Professional Information [NCI] - General Information

Cancell/Cantron/Protocel, also known by the names Sheridan's Formula, Jim's Juice, JS-114, JS-101, 126-F, and the "Cancell-like" products Cantron and Protocel, is a liquid that has been produced in various forms principally by two manufacturers since the late 1930s.[1,2,3] It has been promoted as an effective therapy for cancer and a wide range of other diseases including AIDS, collagen disease, lupus, scleroderma, cystic fibrosis, multiple sclerosis, adult-onset diabetes mellitus, emphysema, Parkinson disease, hemophilia, hypotension, hypertension, and some forms of epilepsy and mental illness.[1,3]

The exact composition of Cancell/Cantron/Protocel is unknown. The U.S. Food and Drug Administration (FDA) has listed the components as inositol, nitric acid, sodium sulfite, potassium hydroxide, sulfuric acid, and catechol.[1,2] The original manufacturer also identified "crocinic acid" as a component;[1] however, information about the nature and origin of this chemical has not been provided, and it does not appear to be a known compound. An independent analysis of one formulation of Cancell/Cantron/Protocel found 12 different compounds, none of which is known to be effective in treating any form of cancer.[1]

General Information About Gastrointestinal Stromal Tumors

Gastrointestinal stromal tumor is a disease in which abnormal cells form in the tissues of the gastrointestinal tract. The gastrointestinal (GI) tract is part of the body's digestive system. It helps to digest food and takes nutrients (vitamins, minerals, carbohydrates, fats, proteins, and water) from food so they can be used by the body. The GI tract is made up of the following organs: Stomach. Small intestine. Large intestine (colon). Gastrointestinal stromal tumors (GISTs)...

Before researchers can conduct clinical drug research in the United States, they must file an Investigational New Drug (IND) application with the FDA. Entelev, which is the original name of the mixture, was assigned an IND number (IND #20258) by the FDA in 1982.[4] The IND currently remains inactive because information about the product's composition and studies showing its therapeutic effectiveness in animals have not been provided to the FDA.[1] In 1989, the FDA was granted a permanent injunction against both principal manufacturers of Cancell/Cantron/Protocel prohibiting them or their agents from distributing the mixture, which was judged an unapproved new drug.

Cancell/Cantron/Protocel has been administered orally, rectally, and topically.[1] Topical skin application is accomplished by dampening a cotton pad with the liquid and taping the moistened pad to the wrist or the ball of the foot after first treating the area with dimethyl sulfoxide. Cancer patients have also been advised to take bromelain, which is a digestive aid, and to avoid high intakes of vitamins C and E while undergoing treatment with Cancell/Cantron/Protocel.[1,3]
