Yoga Intervention for Patients With Prostate Cancer Undergoing External Beam Radiation Therapy: A Pilot Feasibility Study

Effect of yoga as a complementary therapy in prostate cancer survivors: a systematic review

PURPOSE

Currently, available evidence suggests a positive impact of yoga on physical and psychological well-being in patients across different types of cancer, especially breast cancer survivors. However, there are no available systematic reviews on the effects of yoga on male prostate cancer survivors. The objective of the current systematic review is to specifically examine the quality of life, feasibility, and other effects of yoga on prostate cancer survivors.

METHODS

Bibliographic databases such as PubMed/Medline, CINAHL, EMBASE, Cochrane Library, and Google Scholar were searched for studies that were conducted till December 2022 to assess the effect of yoga on prostate cancer survivors. Studies that met predefined eligibility criteria were included. The quality of the included studies was assessed by the Cochrane risk of bias tool, and for single-arm studies, the Newcastle-Ottawa Scale was used.

RESULTS

A comprehensive literature search yielded a total of 137 studies. After careful consideration, this review included five studies involving 129 prostate cancer survivors. The included studies were published between 2012 and 2022. This systematic review observed that yoga has the potential to enhance erectile function, reduce fatigue and urinary symptoms, alleviate psychological stress, boost immune function, and improve the overall quality of life in prostate cancer survivors. Furthermore, it demonstrates the feasibility of incorporating yoga into their regular routine.

CONCLUSIONS

Yoga could be an effective complementary therapy in the management of physical and psychological symptoms experienced by prostate cancer survivors. However, until more comprehensive evidence becomes available, it would be premature to draw definitive conclusions about the effectiveness of yoga in the context of prostate cancer (PCa).

A quality improvement study on the feasibility and potential benefits of a yogic breathing program for cancer survivors and caregivers during treatment in a lodging facility

Background

Complementary and integrative health approaches with a focus on relieving side effects of cancer treatment are popular among cancer patients. Previous studies have investigated the combined effects of yoga postures, breathing, and meditation, but the specific effects of the breathing component are under-reported. Our previous studies indicate that yogic breathing can improve salivary biomarker expression related to stress, immune response, and tumor suppression. We aim to assess the acceptability and feasibility of a yogic breathing program in cancer patients and caregivers during the treatment period.

Methods

In this quality improvement study, we designed a 20-minute yogic breathing regimen and introduced them to all-site cancer patients and their caregivers during the cancer treatment period at a lodging facility, Hope Lodge in Charleston, SC. All interested participants were included as there were no eligibility criteria set for the study. The availability of the class was advertised via intercom, displays, and word of mouth. Participants were taught five different breathing exercises, and after completion of the exercises in a single session, a self-reported quality improvement questionnaire was administered assessing sociodemographic/clinical factors, expectations about the session, and ratings of satisfaction with the session.

Results

During the nine months of the data collection period, 52 participants provided feedback of which patients and caregivers were almost equal numbers. Participants' perception of intervention acceptance, symptom management, satisfaction with the sessions, and future needs for practice indicate that the yogic breathing sessions help improve some of the key symptoms of cancer experience such as stress.

Conclusion

Findings indicate that yogic breathing is acceptable to patients and caregivers and may help alleviate some of the side effects resulting from cancer treatment, and the intervention is feasible at lodging facilities during treatment. Currently, the yogic breathing sessions are conducted on a weekly basis by Hope Lodge volunteers trained by the study team.

The Interplay between Vascular Function and Sexual Health in Prostate Cancer: The Potential Benefits of Exercise Training

Prostate cancer and its associated treatments can cause significant and lasting morbidities, such as cardiovascular and sexual dysfunctions. Various interventions have attempted to prevent or mitigate these dysfunctions. This review summarises the available evidence on the effects of exercise training on markers of cardiovascular disease (as assessed via vascular health outcomes) and sexual health in this prevalent cancer population. Current studies predominantly report blood pressure outcomes as a marker of vascular health, as well as various questionnaires assessing sexual health parameters, in men on active treatment (i.e., hormone or radiation therapies) or post-treatment. Preliminary evidence suggests that exercise interventions may elicit improvements in sexual function, but not blood pressure, in these populations. Future studies in more advanced and varied prostate cancer populations (i.e., those on chemotherapies or immunotherapies, or undergoing active surveillance) are required to ascertain the duration, intensity and frequency of exercise that optimises the effects of exercise training on cardiovascular and sexual dysfunctions (and their relationship) in men during and following treatment for prostate cancer.

Yoga's Biophysiological Effects on Lower Urinary Tract Symptoms: A Scoping Review

BACKGROUND AND OBJECTIVES

Yoga is a mind and body practice that includes relaxation, meditation, breathing exercises, and body postures. It can be effective in enhancing the functioning of several body systems, including the lower urinary tract. Normal lower urinary tract functioning depends in part on the coordination of the bladder, urethra, pelvic floor and other muscles, and the nerves that control them. Lower urinary tract dysfunction can lead to symptoms, that is, stress urinary incontinence (UI), urinary frequency, nocturia, urinary urgency with and without incontinence, and mixed UI. Recent evidence suggests that yoga can improve lower urinary tract symptoms (LUTS). Thus, we performed a scoping review of the literature with regard to the evidence for the effects of yoga on LUTS and factors that may mediate yoga's effects on LUTS with the goal to identify gaps in knowledge regarding the relationship between yoga practice and LUTS.

METHODS

The authors employed the PRISMA extension for Scoping Reviews (PRISMA-ScR) methodological approach, proposed by Tricco et al., by searching the electronic databases, PubMed, Embase, and PsycINFO, for articles using the following keywords: yoga, urinary incontinence, urinary tract, bladder, and urethra. We assessed the quality of the studies using the Joanna Briggs Institute Critical Appraisal Checklist.

RESULTS

Of the 172 articles we found, 8 articles met the inclusion criteria and were reviewed. We found that, despite the use of different protocols, yoga may reduce certain LUTS by increasing the strength of pelvic floor muscle and/or regulating the autonomic nervous system and activating the central nervous system.

CONCLUSIONS

Yoga is a noninvasive practice that may improve some LUTS. Rigorous studies are needed to determine the specific mechanisms through which yoga may affect LUTS.

Growth of Integrative Medicine at Leading Cancer Centers Between 2009 and 2016: A Systematic Analysis of NCI-Designated Comprehensive Cancer Center Websites

Background

Cancer centers have increasingly offered integrative medicine therapies in response to their patients' unmet needs. We evaluated the growth of integrative medicine in leading academic cancer centers in the United States as reflected by their public-facing websites.

Methods

We performed a systematic review of 45 National Cancer Institute (NCI)-designated comprehensive cancer center websites. Two researchers independently evaluated whether the websites provided information regarding integrative medicine modalities and, if so, whether the services were provided in the same health system. They compared the proportion of cancer centers providing the information on each modality in 2016 with the data from the prior study in 2009.

Results

The most common integrative medicine therapies mentioned on the 45 NCI-designated comprehensive cancer center websites were exercise (97.8%) and acupuncture and meditation (88.9% each), followed by yoga (86.7%), massage (84.4%), and music therapy (82.2%). The majority of the websites also provided information on nutrition (95.6%), dietary supplements (93.3%), and herbs (88.9%). The most common therapies offered in the health systems were acupuncture/massage (73.3% each), meditation/yoga (68.9% each), and consultations about nutrition (91.1%), dietary supplements (84.4%), and herbs (66.7%). Compared with 2009, there was a statistically significant increase in the number of websites mentioning acupuncture, dance therapy, healing touch, hypnosis, massage, meditation, Qigong, and yoga (all P < .05).

Conclusions

Leading US cancer centers increasingly present integrative medicine content on their websites, and the majority of them provide these services to patients in the same health systems.

Traditional Chinese Medicine for Sexual Dysfunction: Review of the Evidence

INTRODUCTION

Despite the growing popularity of traditional Chinese medicine (TCM) in the Western world, biomedical students and practitioners struggle to understand TCM and how it relates to their standard diagnosis and treatment practices.

AIMS

To describe the fundamentals of TCM theory and practice relevant to sexual dysfunction; to review and critique the current state of TCM research within Western biomedical literature; and to identify sites for improvement of future research and for collaborative integration of TCM and biomedicine in practice.

METHODS

Information about TCM from an insider perspective was obtained from English-language textbooks and lectures intended to teach Western students its theory and practice. PubMed search using Medical Subject Heading terms for Western sexual diagnoses and TCM treatments was performed in April and October 2017 to represent the evidence for TCM in Western biomedical literature. Articles in non-English languages and without human subjects were excluded.

MAIN OUTCOME MEASURES

27 studies were included in this review. The most commonly studied intervention was acupuncture. An equal number of studies addressed sexual dysfunction in men and women, but only women were included in studies of physically passive mindfulness meditation.

RESULTS

Compared with Western biomedicine, TCM offers a more interdisciplinary and individualized approach to disease and its treatment. This embrace of individual idiosyncrasy in diagnosis and treatment presents a challenge to Western biomedical research norms that rely almost exclusively on quantitative methods that compare large and homogeneous groups with a fixed diagnosis and treatment regimen.

CONCLUSION

TCM offers a very different understanding of the human body, health, and disease from Western biomedicine. There is value in the study and application of these 2 medical systems, particularly for biopsychosocial problems of sexual dysfunction. However, this must be done cautiously, with attention to appropriate study design, to avoid shallow and unscientific cultural appropriation of TCM practices. Chubak B, Doctor A.

Effect of Eischens Yoga During Radiation Therapy on Prostate Cancer Patient Symptoms and Quality of Life: A Randomized Phase II Trial

PURPOSE

A randomized phase II study was performed to measure the potential therapeutic effects of yoga on fatigue, erectile dysfunction, urinary incontinence, and overall quality of life (QOL) in prostate cancer (PCa) patients undergoing external beam radiation therapy (RT).

METHODS AND MATERIALS

The participants were randomized to yoga and no-yoga cohorts (1:1). Twice-weekly yoga interventions were offered throughout the 6- to 9-week courses of RT. Comparisons of standardized assessments were performed between the 2 cohorts for the primary endpoint of fatigue and the secondary endpoints of erectile dysfunction, urinary incontinence, and QOL before, during, and after RT.

RESULTS

From October 2014 to January 2016, 68 eligible PCa patients underwent informed consent and agreed to participate in the study. Of the 68 patients, 18 withdrew early, mostly because of treatment schedule-related time constraints, resulting in 22 and 28 patients in the yoga and no-yoga groups, respectively. Throughout treatment, those in the yoga arm reported less fatigue than those in the control arm, with global fatigue, effect of fatigue, and severity of fatigue subscales showing statistically significant interactions (P<.0001). The sexual health scores (International Index of Erectile Function Questionnaire) also displayed a statistically significant interaction (P=.0333). The International Prostate Symptom Score revealed a statistically significant effect of time (P<.0001) but no significant effect of treatment (P=.1022). The QOL measures had mixed results, with yoga having a significant time by treatment effect on the emotional, physical, and social scores but not on functional scores.

CONCLUSIONS

A structured yoga intervention of twice-weekly classes during a course of RT was associated with a significant reduction in pre-existing and RT-related fatigue and urinary and sexual dysfunction in PCa patients.

Yoga Therapy in Children with Cystic Fibrosis Decreases Immediate Anxiety and Joint Pain

This study was designed to determine whether yoga might alleviate symptoms of pain, sleep disturbance, anxiety, and depression in children with cystic fibrosis (CF). CF is the most common genetic, life-limiting chronic disease among Caucasian populations. It primarily affects the lungs but also many other secretory organs and consequently leads to significant morbidities. Research has shown that children with CF have significantly increased depression, anxiety, and pain compared to their healthy counterparts. Subjects participated in six one-on-one sessions over a 10-week period with a certified instructor who designed each yoga practice based on a preestablished list of 30 yoga asanas. Questionnaires evaluating pain, sleep disturbance, sustained anxiety, immediate anxiety, and depression were administered. Differences between premeasures and postmeasures were evaluated using a two-sided test. Twenty subjects were assessed (12 females/8 males), median age of 11 (7-20) years. Mean immediate anxiety scores decreased (before session to after session 29 to 23.6, respectively, p < 0.001). Joint pain improved (3.25 to 3.65, p = 0.028). CFQ-R emotion subscale improved from 79.2 to 85 (p = 0.073), and the respiratory subscale improved from 66.7 to 79.2 (p = 0.076). Other results were less notable. We conclude that yoga may reduce immediate anxiety and joint pain in patients with CF.
