Yoga improves quality of life in women with breast cancer undergoing radiation therapy

MD Anderson study first to compare benefits of mind-body practices to simple stretching exercises

2011-05-19

(Press-News.org) HOUSTON — For women with breast cancer undergoing radiation therapy, yoga offers unique benefits beyond fighting fatigue, according to new research from The University of Texas MD Anderson Cancer Center.

While simple stretching exercises improved fatigue, patients who participated in yoga that incorporated yogic breathing, postures, meditation and relaxation techniques into their treatment plan experienced improved physical functioning, better general health and lower cortisol (stress hormone) levels. They also were better able to find meaning in their cancer experience.

The findings, to be presented next month in an oral session at the 47th annual meeting of the American Society of Clinical Oncology by Lorenzo Cohen, Ph.D., professor and director of the Integrative Medicine Program at MD Anderson, are the latest in an ongoing effort to scientifically validate the age-old belief that mind-body interventions have a beneficial impact on the health of cancer patients. The research was conducted in collaboration with India's largest yoga research institution, Swami Vivekananda Yoga Anusandhana Samsthana in Bangalore, India.

The study assessed, for the first time, yoga benefits to cancer patients by comparing their experience with patients in an active control group who integrated simple, generic stretching exercises into their lives. "The combination of mind and body practices that are part of yoga clearly have tremendous potential to help patients manage the psychosocial and physical distress associated with treatment and life after cancer, beyond the benefits of simple stretching," said Cohen.

To conduct the study, 163 women with breast cancer (stage 0-3) averaging 52 years of age were randomized to one of three groups: 1) yoga; 2) simple stretching; or 3) no instruction in yoga or stretching. Participants in the yoga and stretching groups attended sessions specifically tailored to breast cancer patients for one hour three days a week throughout their six weeks of radiation treatment.

Participants were asked to report on their quality of life, including fatigue, daily functioning, benefit finding, depression and spirituality. Saliva samples were collected and electrocardiogram tests were administered at baseline, end of treatment, and at one, three and six months post-treatment.

After completing radiation treatment, only the women in the yoga and stretching groups reported a reduction in fatigue. At one, three and six months after radiation therapy, women who practiced yoga during the treatment period reported greater benefits to physical functioning and general health. They were more likely to perceive positive life changes from their cancer experience than either other group.

Women who practiced yoga also had the steepest decline in their cortisol across the day, indicating that yoga had the ability to regulate this stress hormone. This is particularly important because higher stress hormone levels throughout the day, known as a blunted circadian cortisol rhythm, have been linked to worse outcomes in breast cancer.

According to Cohen, developing a yoga practice also helps patients after completing cancer treatment. "The transition from active therapy back to everyday life can be very stressful as patients no longer receive the same level of medical care and attention. Teaching patients a mind-body technique like yoga as a coping skill can make the transition less difficult."

Through a grant from the National Cancer Institute – the largest ever awarded for the study of yoga in cancer – Cohen and his team will next conduct a Phase III clinical trial in women with breast cancer to further determine the mechanisms of yoga that lead to improvement in physical functioning, quality of life, and biological outcomes during and after radiation treatment. A secondary aim of the trial, but one of great importance, stressed Cohen, is assessing cost efficiency analysis for the hospital, health care usage costs in general, and examining work productivity of patients.

MD Anderson recognizes the growing body of research indicating that relaxation-based interventions can contribute to the well-being of people with cancer. Through the Integrative Medicine Program, complementary therapies, such as yoga, are offered at MD Anderson's Integrative Medicine Center, and are used in concert with mainstream care to manage symptoms, relieve stress, enhance quality of life, and improve outcomes for patients and their caregivers. MD Anderson's Integrative Medicine faculty also conduct research in the biological and behavioral effects of mind-body based interventions; the anti-cancer potential of natural compounds; and, acupuncture to treat common cancer treatment-related side effects.

Accurate Mammograms With Breast Implants

2011-05-19

Breast implants may obstruct some mammogram imaging, but this does not mean breast implants render mammograms ineffective as a means of screening for breast cancer. Breast augmentation surgery remained the most popular cosmetic surgery procedure in 2010, with 296,000 procedures performed last year alone, according the annual statistics report from the American Society of Plastic Surgeons. With that number continuing an upward trend over the past decade, more mammogram technicians and radiologists have experience conducting and reading the results of mammograms of women ...

Artificial tissue promotes skin growth in wounds

2011-05-19

ITHACA, N.Y. - Victims of third-degree burns and other traumatic injuries endure pain, disfigurement, invasive surgeries and a long time waiting for skin to grow back. Improved tissue grafts designed by Cornell scientists that promote vascular growth could hasten healing, encourage healthy skin to invade the wounded area and reduce the need for surgeries. These so-called dermal templates were engineered in the lab of Abraham Stroock, associate professor of chemical and biomolecular engineering at Cornell and member of the Kavli Institute at Cornell for Nanoscale Science, ...

Hospitals misleading patients about benefits of robotic surgery, study suggests

2011-05-19

An estimated four in 10 hospital websites in the United States publicize the use of robotic surgery, with the lion's share touting its clinical superiority despite a lack of scientific evidence that robotic surgery is any better than conventional operations, a new Johns Hopkins study finds. The promotional materials, researchers report online in the Journal for Healthcare Quality, overestimate the benefits of surgical robots, largely ignore the risks and are strongly influenced by the product's manufacturer. "The public regards a hospital's official website as an authoritative ...

Gambling problem exposed as access grows

2011-05-19

A new paper by University of Calgary psychologist Dr. David Hodgins says the proliferation of gambling opportunities around the world, particularly online, is increasing the visibility of gambling disorders and giving access to people who previously had no exposure to gambling opportunities. Hodgins, head of the university's Addictive Behaviours Laboratory, says gambling disorders are often found in conjunction with other mental health and substance-abuse disorders. In an online version of the medical journal, The Lancet, Hodgins says the study of problem gambling is ...

Growing Numbers Of Young Patients In Nursing Homes

2011-05-19

The common view of a nursing home is a building full of old people, in walkers and wheelchairs, white hair and bingo games. A recent story from the Associated Press notes that there is a growing population of young (less than 65 years-old) people in nursing homes and long-term care facilities. While those 30 and younger only number one percent of the nursing home population, the number of those younger than 65 have increased 22 percent in the last eight years. A report from NPR notes that ages 31-65 now make up 14 percent of nursing home populations. This is up from ...

Species extinction rates have been overreported, new study claims

2011-05-19

The most widely used methods for calculating species extinction rates are "fundamentally flawed" and overestimate extinction rates by as much as 160 percent, life scientists report May 19 in the journal Nature. However, while the problem of species extinction caused by habitat loss is not as dire as many conservationists and scientists had believed, the global extinction crisis is real, says Stephen Hubbell, a distinguished professor of ecology and evolutionary biology at UCLA and co-author of the Nature paper. "The methods currently in use to estimate extinction ...

High pregnancy weight gain can lead to long-term obesity

2011-05-19

Gaining more than the recommended weight during pregnancy can put women at increased risk of becoming obese and developing related health problems, including high blood pressure, later in life. These are the latest findings from researchers at the Avon Longitudinal Study of Parents and Children (ALSPAC)/Children of the 90s at the University of Bristol. Weight gain during pregnancy is necessary for the growth and development of the fetus but the study, which looked at the health of 3,877 women 16 years after they gave birth, found that those who gained more than the ...

Study Finds Florida's Motor Vehicle Safety Laws Lacking

2011-05-19

The Emergency Nurses Association (ENA) recently released its third annual scorecard on the safety of each state's roads. When it comes to laws meant to prevent car accidents, the news for Florida is not so good. Out of 14 categories, Florida received a mediocre score of seven. While the score is not the worst received - North Dakota scored lowest at four - it certainly was not one of the top scores. The scorecard ranked the safety of each state's roads based on the presence or absence of 14 different motor vehicle safety laws. The laws included those for mandatory seatbelt ...
