Integrative Care: What’s Safe During and After Treatment Aminah Keats, ND, FABNO Director of Naturopathic Medicine Cancer Treatment Centers of America Philadelphia, PA 1 © 2012 Rising Tide What is Naturopathic Medicine? Naturopathic Medicine is a distinctively natural approach to health and healing that recognizes the integrity of the whole person. It emphasizes the treatment of disease through the stimulation, enhancement, and support of the inherent healing capacity of the person. 2 © 2011 Rising Tide Naturopathic Medical Education • 5 accredited naturopathic medical schools in the United States and 2 in Canada • Pre-requisite pre-med undergraduate degree • 4 year graduate medical education 2 years basic sciences 2 years clinical sciences • 2 sets of Board Exams • Optional Residency • Specialty training: Fellowship of the Oncology Board of Naturopathic Physicians Naturopathic Medicine Modalities • • • • • • • • • • Nutritional Supplementation Homeopathy Botanical Medicine Clinical Nutrition Counseling Hydrotherapy Physical Medicine Acupuncture Minor surgery (certain states) Intravenous and injection therapy (certain states) 4 © 2011 Rising Tide Patient Empowerment Team © 2012 Rising Tide Evaluating Natural Therapies: Factors to Consider • • • • • Drug-herb/nutrient interaction Condition-herb/nutrient interaction Published Evidence of Effectiveness Complementary vs. Alternative treatment Cost Evaluating Natural Therapies: Drug-herb/nutrient Interaction • Certain supplements may effect the pharmacokinetics of certain medications -Decrease in effectiveness i.e. St. John’s Wort and Taxol -Increase in side effects i.e. Folic acid and Xeloda Evaluating Natural Therapies: Condition-herb/nutrient Interaction • Licorice root can potentially increase blood pressure when large doses are taken over extended periods • Phytoestrogenic herbs are not advised in patients with breast cancer due to theoretical concerns i.e. Licorice, Red clover Evaluating Natural Therapies: Published Evidence of Effectiveness Is there scientifically validated evidence of effectiveness? Example: L-glutamine and oxaliplatin-induced peripheral neuropathy 86 pts with metastatic colorectal cancer received oxaliplatin/5-FU/leucovorin on days 1, 8, and 15 Pts were randomized to receive or not receive glutamine Lower percentage of grade 1-2 peripheral neuropathy was observed in glutamine group after 2 cycles Lower incidence of grade 3-4 peripheral neuropathy was noted in glutamine group after 4 cycles and 6 cycles Interference with activities of daily living was lower in glutamine group Need for oxaliplatin dose reduction was lower in glutamine group No difference in response to chemo or survival Oncologist. 2007 Mar;12(3):312-9.
