Yoga-based exercise has proven to be beneficial for practitioners, including cancer survivors. This study reports on the improvements in physical fitness for 20 breast cancer survivors who participated in a six-month yoga-based (YE) exercise program. Results are compared to a comprehensive exercise (CE) program group and a comparison (C) exercise group who chose their own exercises. “Pre” and “post” fitness assessments included measures of anthropometrics, cardiorespiratory capacity, strength and flexibility. Descriptive statistics, effect size (d), dependent sample ‘t’ tests for all outcome measures were calculated for the YE group. Significant improvements included: decreased % body fat (−3.00%, d = −0.44, p < 0.001); increased sit to stand leg strength repetitions (2.05, d = 0.48, p = 0.003); forward reach (3.59 cm, d = 0.61, p = 0.01); and right arm sagittal range of motion (6.50°, d = 0.92, p= 0.05). To compare YE outcomes with the other two groups, a one-way analysis of variance (ANOVA) was used. YE participants significantly outperformed C participants on “forward reach” (3.59 cm gained versus −2.44 cm lost), (p = 0.009) and outperformed CE participants (3.59 cm gained versus 1.35 cm gained), but not statistically significant. Our results support yoga-based exercise modified for breast cancer survivors as safe and effective.

Background Diagnosis and treatment of prostate cancer is associated with anxiety, fear, and depression in up to one-third of men. Yoga improves health-related quality of life (QoL) in patients with several types of cancer, but evidence of its efficacy in enhancing QoL is lacking in prostate cancer. Methods In this randomized controlled study, 29 men newly diagnosed with localized prostate cancer were randomized to yoga for 6 weeks (n = 14) or standard-of-care (n = 15) before radical prostatectomy. The primary outcome was self-reported QoL, assessed by the 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) at baseline, preoperatively, and 6 weeks postoperatively. Secondary outcomes were changes in immune cell status and cytokine levels with yoga. Results The greatest benefit of yoga on QoL was seen in EPIC-sexual (mean difference, 8.5 points), FACIT-F (6.3 points), FACT-Functional wellbeing (8.6 points), FACT-physical wellbeing (5.5 points), and FACT-Social wellbeing (14.6 points). The yoga group showed increased numbers of circulating CD4+ and CD8+ T-cells, more production of interferon-gamma by natural killer cells, and increased Fc receptor III expression in natural killer cells. The yoga group also showed decreased numbers of regulatory T-cells, myeloid-derived suppressor cells, indicating antitumor activity, and reduction in inflammatory cytokine levels (granulocyte colony-stimulating factor [0.55 (0.05–1.05), p = 0.03], monocyte chemoattractant protein [0.22 (0.01–0.43), p = 0.04], and FMS-like tyrosine kinase-3 ligand [0.91 (−0.01, 1.82), p = 0.053]. Conclusions Perioperative yoga exercise improved QoL, promoted an immune response, and attenuated inflammation in men with prostate cancer. Yoga is feasible in this setting and has benefits that require further investigation. Trial registration clinicaltrials.org (NCT02620033).

Introduction Chronic inflammation can remain many years after the completion of cancer treatment and is associated with cancer recurrence. The purpose of this study was to examine how a 16-week therapeutic yoga program (TYP) modulates the cytokine profile in heterogeneous cancer survivors. Methods Eligible participants were 18 years of age or older and clinically diagnosed with cancer. Consenting participants were asked to attend three, 75-min sessions weekly of TYP with meditation. Seventeen patients provided blood samples at baseline and end of study. Eight cytokines (interferon (IFN)-γ; interleukin (IL)-1b, IL-1ra, IL-4, IL-6, IL-8, IL-10; and tumor necrosis factor (TNF)-α), three receptors (sIL-6R, sTNFRI, sTNFRII), and C-reactive protein (CRP) were quantified. Results Patients were 59.6 ± 7.3 years old; over half (56%) were overweight or obese BMI ≥ 25 kg/m 2 ); majority were female (71%) and breast cancer survivors (65%), of which 44% were Hispanic. Marked reductions were observed in all cytokines except IL-4, with significant reductions ( p < 0.05) found in IL-1b (− 13%) and IL-1ra (− 13%). No significant changes were observed in soluble cytokine receptors or CRP. Conclusions TYP led to significant reduction in circulating cytokines associated with chronic inflammation in a heterogeneous sample of cancer survivors.

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.
