Nutritional Supplementation During Cancer Chemotherapy
By Dale Petersen MD –
Studies have repeatedly shown that people tend to believe the first thing they hear or read about a subject even when informed that the information was false. Unfortunately, this is true of physicians and publication of medical research.
I was reminded of this phenomenon recently when an individual who has sought my advice over the years was found to have lung cancer. When she opted to pursue conventional treatment with chemotherapy and radiation she was told to avoid all nutritional supplements because they would interfere with the effectiveness of her medical treatment.
The recommendation to withhold nutritional supplementation cannot be supported on any objective evidence. The widely held belief originated from a single faulty medical study published in 2006 (Bairati I, Meyer F, Jobin E, et al. Antioxidant vitamins supplementation and mortality: a randomized trial in head and neck cancer patients. Int J Cancer 2006;119(9):2221-2224. The study’s authors concluded that while patients taking antioxidant supplements had fewer serious adverse effects from chemotherapy they were more likely to have a recurrence of their cancer and die more quickly than those not taking antioxidants.
The authors published a follow-up article in 2008 in which they reported that the patients who had died from recurrent cancer were those who had continued to smoke. (Meyer F, Bairati I, Fortin A, et al. Interaction between antioxidant vitamin supplementation and cigarette smoking during radiation therapy in relation to long-term effects on recurrence and mortality: a randomized trial among head and neck cancer patients. Int J Cancer 2008;122(7):1679-1683.) The risk of cancer recurrence and earlier death was not due to supplementation with antioxidant nutrients but to continued tobacco use!
Unfortunately, the clarification came too late to benefit future cancer patients. The initial faulty conclusion continues to be considered factual by U.S. physicians. Most people entering a course of cancer chemotherapy are warned to avoid all nutritional supplements, not just the antioxidants brought into question in the original study.
What about the scientific facts and observed experience? Scientific studies have overwhelmingly found that people who take nutritional supplements, including antioxidants, during conventional cancer treatment experience fewer adverse effects, have a higher quality of life, and generally have a better outcome than those who do not. I believe this explains why the Cancer Treatment Centers of America, which routinely include nutritional support in their treatment regimens, have dramatically higher success rates than other cancer treatment centers.
If you or someone you care about is found to have cancer encourage them to look at the facts regarding nutritional supplementation and chemotherapy. Don’t lessen the chance of recovery by blindly accepting the false premise that supporting the body’s ability to weather the effects of chemotherapeutic drugs will lessen their effectiveness.
