New study investigates use of soy-rich diet for preventing chronic pain after breast cancer surgery
Montreal, September 1, 2010 - The potential
health benefits associated with a soy-rich diet have been a source
of interest and debate for many years. Several studies have hinted
at its great potential for relieving post-traumatic and osteopathic
pain. Now, a breakthrough study, focusing on the benefits of soy in
the prevention of chronic pain after breast cancer surgery, has
been launched by researchers at the Alan Edwards Pain Management
Unit of the 㽶Ƶ Health Centre (MUHC) and McGill
University.
“If we can demonstrate that a soy-rich pre-surgery diet, is both
safe and effective for the prevention of chronic post-surgical
pain, the clinical implications will be significant and could help
many women around the world,” explains Dr. Yoram Shir, principal
investigator of the study and Director of the MUHC Alan Edwards
Pain Management Unit, who is also a Professor of Anesthesia and
Edwards Chair in Clinical Pain at 㽶Ƶ.
Chronic pain after breast cancer surgery is the most common cause
for long-term morbidity in women diagnosed with breast cancer, with
an incidence that can be higher than 50%. This pain can be
resistant to treatment and last for years, burdening women with its
physical, emotional and social consequences. This new National
Institutes of Health-funded study will determine if a diet enriched
with soy protein, consumed by women for two weeks prior to surgery,
could prevent the development of chronic pain. "If shown to be
efficacious, this would be a natural and safe preventive treatment
that is easily incorporated into the everyday diet,” says Dr. Shir.
Our daily diet can also be enriched with soy protein through shelf
products like tofu and soy milk.
There is currently no proven effective method for the prevention of
chronic postoperative pain," explains Dr. Shir. “Measures such as
pain-relieving medications, commonly used to relieve acute pain
after surgery, are largely ineffective in preventing acute
post-surgical pain from becoming chronic.” Over 22,000 new cases of
breast cancer in women are diagnosed each year in Canada and 6,000
in Quebec; most will undergo surgery as part of their comprehensive
cancer therapy.
Dr. Shir will be attending the 13th World Congress on Pain in
Montreal from August 20 to September 2, 2010.
