The only study ever published on the use of this in cancer patients was sponsored by the National Cancer Institute and conducted at the Mayo Clinic and three other prominent oncological centers in the USA. The results were published in The New England Journal of Medicine (NEJM) in 1982.
In this article “A clinical trial of Apricot Seed Extract medicinal form in the treatment of human cancer,” Dr. Moertel, the head researcher, reported that of the 178 patients that were accepted in the study “not one patient was cured or even stabilized”.
Furthermore, he said that “several patients experienced symptoms of cyanide toxicity” and that “blood levels of cyanide approaching the lethal range” were reported. “this therapy has had its day in court…” says Moertel and ends authoritatively, “The evidence, beyond reasonable doubt, is that it doesn’t benefit patients with advanced cancer, and there is no reason to believe that it would be any more effective in the earlier stages of the disease.”
What’s disappointing about the article is the editorial bias of the NEJM. Why did the NCI and the Mayo Clinic bypass all scientific protocol? This study had no control group. It was not designed properly and not one of the researchers had any experience with the therapy. The NEJM, in normal conditions, will not publish studies that are not peer reviewed by experts on the subject. There are very few experts in this area, all of which have worked with Dr. Francisco Contreras.
