http://www.pubmedcen...i?artid=1653400World Without Cancer; The Story of Vitamin B17. G. Edward Griffin. American
Media, Thousand Oaks, CA, 1974, Parts I-II, 526 pages.
This book is written as an endorsement of Laetrile, which is also known as Vitamin B17, as a possible prophylactic and therapeutic agent against cancer. Laetrile is currently banned by the FDA in the United States for anti-cancer use.
The stated hypothesis is that cancer, like scurvy or pellagra. is a deficiency disease caused by the lack of an essential food element in the modern diet, specifically B17. Although it was not necessary for the purpose of this exposition. the author also defends the unaccepted anti-cancer drug, Krebiozen. (Yet, Krebiozen and Laetrile have nothin in common.) It should be stated that this reviewer, at the time that Krebiozen was being evaluated over a decade ago, was Head of the Laboratory and Clinical Trials Section of the National Cancer Institute and a member of the panel which disapproved the request for a clinical trial for Krebiozen. The grounds for rejection of Krebiozen were that, for specific sites of cancer, it was demonstrably less effective than accepted medical practice and thus prevented patients from receiving the best available mode of therapy.
The author maintains that the missing food nutrient is part of the nitriloside family which is found particularly in the seeds of the fruit family containing bitter almond, apricot, etc. It is also contained in grasses, maize, sorghum, millet and other foods generally not plentiful in the modern diet. The theory behind the claimed anti-carcinogenic activity of vitamin B,7 is as follows:
Cancer is an over-healing process. The body normally produces trophoblast cells to overcome specific damage to or to prevent the aging of normal tissues. However, under certain conditions, the trophoblast cells are allowed to undergo uncontrolled proliferation. One condition is when the pancreas is weak; the other is when the kinds of foods we eat consume all of the pancreatic enzymes for their digestion. The role of the pancreatic enzymes in cancer control is to digest away the electronically-charged protein coat covering the trophoblast cell thus exposing it to the white blood cells for disposal. According to the author, the B1, moleciUle contains four components: two units of glucose, a unit of benzaldehyde and orle of cyanide. These last two compounds act synergistically against the cancer cell and only the cancer cell contains an enzyme which breaks down this B17 molecule.
Of course, this is only one of several theories of the mechanism of carcinogenesis. The rest of Part I emphasizes the relative failure of conventional cancer therapy, (radiation, surgery and chemotherapy), to achieve significant remission rates and the markedly reduced quality of life which results from such therapy. Part II is devoted to the politics of cancer therapy and cancer research and of the organizations like the Food and Drug Administration, American Cancer Society and the American Medical Association which are opposed to the nutritional concept of the etiology of cancer. The author accepts the "conspiracy" theory, i.e. that policy-rtiakers in the medical, pharmaceutical, research and fund-raising organizations deliberately or unconsciously strive not to prevent or cure cancer in order to perpetuate their functions.
Unfortunately, in evaluating the scientific quality of the book, one must state that the use of the anecedotal reports of remissions makes it virtually impossible to justify a proper clinical trial of Laetrile. Also, there is no objective presentation of the results of valid animal experiments which have demonstrated the efficiency of this compound. Although the book is an emotional plea for the unrestricted use of the Laetrile as an anti-tumor agent, the scientific evidence to justify such a policy does not appear within it.
