A Danish study evaluated the survival of patients with end-stage cancer who received supplements of coenzyme Q10 and a mixture of other antioxidants including vitamin C, selenium, folic acid and beta-carotene. During a period of 9 years, 40 patients who had end-stage cancer were included. Primary cancers were located in the breast, brain, lungs, kidneys, pancreas, esophagus, stomach, colon, prostate, ovaries and skin. Median predicted survival was 12 months, whereas median actual survival was 17 months, a greater than 40% longer survival than predicted.
