Can mind-body therapies enhance breast cancer care?
Newly updated clinical guidelines from the Society for Integrative Oncology (SIO), suggest they can and that women would get real benefits from having greater access to them.
In putting the new guidelines together researchers from a range of respected institutions in the US and Canada analysed which integrative treatments are most effective and safe for patients with breast cancer.
Their review adds to the growing literature on integrative therapies for patients with breast cancer and other cancer populations. It was published in CA: A Cancer Journal for Clinicians, a publication of the American Cancer Society.
» Studies show that alternatives treatments are popular with cancer patients to help them manage a range of symptoms.
» Doctors are often under-confident in recommending these because they fear lack of evidence.
» New guidelines from the Society for Integrative Oncology (SIO), based on review of high quality evidence, suggest that a range of alternative treatments can be used with confidence.
» These include meditation, music therapy, massage, acupuncture and yoga.
Alternatives are popular
The researchers evaluated more than 80 different therapies and developed grades of evidence. Based on those findings, the Society for Integrative Oncology makes the following recommendations:
“Studies show that up to 80% of people with a history of cancer use one or more complementary and integrative therapies, but until recently, evidence supporting the use of many of these therapies had been limited,” said Heather Greenlee, ND, PhD, assistant professor of Epidemiology at Columbia University’s Mailman School of Public Health, and past president of SIO.
“Our goal is to provide clinicians and patients with practical information and tools to make informed decisions on whether and how to use a specific integrative therapy for a specific clinical application during and after breast cancer treatment,” she adds.
Making the grade
In their systematic evaluation of high quality clinical trials, the researchers assigned letter grades to therapies based on the strength of evidence. A letter grade of “A” indicates that a specific therapy is recommended for a particular clinical indication, and there is high certainty of substantial benefit for the patient.
Meditation had the strongest evidence supporting its use, and is recommended for reducing anxiety, treating symptoms of depression, and improving quality of life, based on results from five trials. Music therapy, yoga, and massage received a B grade for the same symptoms, as well as for providing benefits to breast cancer patients. Yoga received a B grade for improving quality of life based on two recent trials. Yoga and hypnosis received a C for fatigue.
“The routine use of yoga, meditation, relaxation techniques, and passive music therapy to address common mental health concerns among patients with breast cancer is supported by high levels of evidence,” said Debu Tripathy, MD, chair of Breast Oncology at The University of Texas MD Anderson Cancer Center, and a past president of SIO. “Given the indication of benefit coupled with the relatively low level of risk, these therapies can be offered as a routine part of patient care, especially when symptoms are not well controlled.”
Acupressure and acupuncture received a B grade as an addition to drugs used for reducing chemotherapy-induced nausea and vomiting.
Disappointingly, there was a lack of strong evidence supporting the use of ingested dietary supplements and botanical natural products as part of supportive cancer care and to manage treatment-related side effects. This finding, however, could reflect the general paucity of studies in this area.
“Patients are using many forms of integrative therapies with little or no supporting evidence and that remain understudied,” noted Dr. Greenlee. “This paper serves as a call for further research to support patients and healthcare providers in making more informed decisions that achieve meaningful clinical results and avoid harm.”
