Introduction and Objectives: New diagnosis of prostate cancer (PCa) may lead to anxiety, mental distress, fear and depression in up to 30% of men, which can contribute to poor quality of life (QOL). Recent research on Yoga in cancer patients has shown significant improvement in health related QOL, emotional health and fatigue. Given the lack of randomized clinical data regarding the effects of Yoga in PCa, we performed this study to evaluate the potential impact of Yoga on disease-specific QOL in men undergoing radical prostatectomy (RP) for PCa.

Material and Method: We randomly assigned newly diagnosed men with localized prostate cancer to Yoga (n = 15) or standard of care (n= 15) prior to their RP. Yoga was given to the intervention group twice a week for 6 weeks for 60 minutes before the surgery and then re-initiated 3 to 6 weeks after the surgery for another six weeks. Self-report measures of QOL [ Expanded Prostate Index Composite (EPIC), Functional Assessment of Cancer Therapy-Prostate (FACT-P), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), Functional Assessment of Cancer Therapy-General (FACT-G) and Five Facets of Mindfulness Questionnaire (FFMQ) primary outcomes], blood specimen (cytokine and immune markers; secondary outcome) were collected at baseline, prior to the surgery and 6 weeks after surgery.

Results: Improvements in EPIC sexual domain (mean difference: 8.5 points), FACT-P (mean difference: 5.3 points), FACIT-F (mean difference: 5.4 points), and FACT-G (mean difference: 7.2 points) were seen at 6 weeks in the Yoga arm compared with controls. Greatest benefit of Yoga was seen in the subdomains of EPIC sexual function (mean difference: 8.9 points), EPIC sexual bother (mean difference: 7.6 points), FACT emotional wellbeing (mean difference: 5.4 points), FACT functional wellbeing (mean difference 8.3 points) and FACT social wellbeing (mean difference 14.1 points). We identified statistically significant reduction in the inflammatory cytokines- granulocyte colony-stimulating factor (G-CSF; 0.55 [0.05 - 1.05]; p-value = 0.03), Monocyte chemoattractant protein (MCP-1; 0.22 [0.01 - 0.43]; p-value = 0.04), FMS-like tyrosine kinase-3 ligand (FLT-3 L; 0.91 [-0.01 - 1.82]; p-value = 0.053) in the Yoga group during the same time period.

Conclusions: A structured Yoga intervention in the preoperative setting improved QOL, especially in the domains of sexual function, social, emotional and functional well-being as well as fatigue. Yoga positively modulates chronic low-grade inflammation which may impact tumor microenvironment. Yoga is feasible and safe and has promising benefits to physical, mental and emotional well-being. Health care providers can utilize the preoperative period as a window of opportunity for an intervention and a teaching moment for the patient to enhance their overall health. Further integrated large-scale research into molecular impact of yoga on markers of inflammation and immune function are essential.
