Yoga improves quality of life in men with new diagnosis of prostate cancer

Via questionnaires, the team documented the men's perceived quality of life at the start of yoga, at the time of surgery and after surgery. Men who did not do yoga completed the same questionnaires at study enrollment and at the other two junctures.

The team drew blood samples before the men began yoga and after all sessions were completed. Samples were also taken from men who did not do yoga.

Sense of well-being

"What we found was very interesting," Dr. Kaushik said. "Yoga improved quality of life in men compared to the standard of care, specifically on the fatigue scale, meaning they were less tired; on sexual function; and on their functional, physical and social well-being."

A more robust immune response and lower levels of inflammation were observed in the yoga group, he added.

"This is positive data and further large-scale studies are needed, for which this pilot study can be a model," Dr. Kaushik said.

Biomarkers and yoga

The primary study outcome was self-reported quality of life assessed by the questionnaires. Changes in immune cell status and inflammatory markers with yoga were secondary outcomes.

The yoga group showed increased numbers of circulating CD4+ and CD8+ T cells, which are important contributors to immune health. Among other markers, the yoga group also exhibited a reduction in inflammatory markers called cytokines.

The median age of participants was 56 years in the yoga group and 60 years in the standard of care group.

Yoga has been studied in breast cancer, but not at the level of detail of this study, matching self-reported quality of life data with markers of immune response and inflammation, Dr. Kaushik said.

"If we are able to encourage patients to do a small, inexpensive and easy-to-implement intervention that can have a big impact, then why not?" he said.
