Report Card on Complementary Therapies for Breast Cancer
Report Card on Complementary Therapies for Breast Cancer: Meditation and Yoga Get “A” Grade for Easing Anxiety and Mood.
First Clear Guidelines Issued on Use of Complementary Therapies for Breast Cancer.
Over eighty percent of breast cancer patients in the United States use complementary therapies following a breast cancer diagnosis, but there has been little science-based guidance to inform clinicians and patients about their safety and effectiveness. In newly published guidelines from the Society for Integrative Oncology, researchers at Columbia University’s Mailman School of Public Health and the Herbert Irving Comprehensive Cancer Center with colleagues at MD Anderson Cancer Center, University of Michigan, Memorial Sloan Kettering, and other institutions in the U.S. and Canada, analyzed which integrative treatments appear to be most effective and safe for patients. They evaluated more than 80 different therapies.
Meditation, yoga, and relaxation with imagery were found to have the strongest evidence supporting their use. They received an “A” grade and are recommended for routine use for anxiety and other mood disorders common to breast cancer patients. The same practices received a “B” grade for reducing stress, depression, and fatigue, but are also endorsed for most breast cancer patients. Acupuncture received a “B” grade for controlling chemotherapy induced nausea and vomiting and can be recommended to most patients. More than 30 interventions, including some natural products and acupuncture for other conditions, had weaker evidence of benefit due to either small study sizes or conflicting study results, and received a “C” grade. Seven other therapies were deemed unlikely to provide any benefit and are not recommended. One therapy was found to be harmful: acetyl-l-carnitine, which is marketed to prevent chemotherapy-related neuropathy, and actually increased risk for the condition.
