Abstract
Dr. Hoffer has been a practising psychiatrist in Victoria since 1967. During this time he has treated more than 200 female breast cancer patients with niacin, beta-carotene, selenium, vitamin C, Q10 and zinc. We compared the outcomes of Dr. Hoffer's nonmetastatic patients who were diagnosed from 1989 to 1996 with those from two sets of controls. The first set of controls was obtained as matched controls. The second set of controls includes all the female nonmetastatic breast cancer patients diagnosed at the Victoria office of the BC Cancer Agency between 1989 and 1996 who did not take large doses of vitamins as far as can be known. Using the Cox proportional hazards model and the aligned rank test we found that breast cancer patients' life times for Dr. Hoffer's patients are shorter than those of the control patients.
