Convergent priorities and tensions: a qualitative study of the integration of complementary and alternative therapies with conventional cancer treatment.

PURPOSE: Demand for complementary and alternative medicine (CAM) is high among cancer patients. This, alongside growing evidence for the efficacy of some CAM therapies, is driving change within cancer centres, where evidence-based CAM therapies are increasingly provided alongside standard cancer treatments. In Australia, commitment to equitable access to healthcare is strong, and some cancer centres are now providing integrative services at no cost to the patient. This represents a significant shift in healthcare provision. This study aimed to examine health professional and patient dynamics in an integrated cancer service where CAM is provided at no cost to patients alongside standard cancer treatments. It specifically sought to understand what might drive or hinder further integration of CAM with standard treatment in the cancer context. METHODS: Qualitative interviews were undertaken with twenty key stakeholders-cancer patients, cancer nurses, and oncologists-who were delivering or receiving care in an Australian public hospital where acupuncture services are provided at no cost to patients alongside standard chemotherapy and radiation treatments. RESULTS: Findings point to key areas where the concerns and priorities of cancer patients, cancer nurses, and oncologists converge and diverge in ways that reflect core personal and professional interests regarding patient care needs, the evidence base for CAM efficacy and safety, and rising healthcare costs. CONCLUSIONS: Understanding points of convergence and divergence could assist clinicians and service providers in negotiating ways forward for integrative cancer services.

Comparison of integrative medicine centers in the USA and Germany: a mixed method study.

PURPOSE: Integrative medicine (IM) has received increasing attention since the 1990s, but few studies have explored the key factors of the IM model in health care. This study aimed to describe the IM model in leading centers operating in the USA and Germany. METHODS: A 28-item structured survey and semi-structured interviews were conducted in six centers providing integrative medicine in the USA and Germany, and were analyzed using a convergent mixed-method approach. RESULTS: The elements in common across all six centers were the following: (1) involvement of general physicians (GP) in delivering complementary and alternative medicine (CAM) services; (2) requirement for GP or medical referral or recommendation to CAM services; (3) involvement of an integrative physician (IP) as a "gatekeeper"; (4) focus on research, education, and clinical practice; and (5) ongoing academic activities. The key elements differentiating the two countries were the following: (1) level of requirements for GP referral to CAM services; (2) differences in IM service delivery, including treatment modalities used; (3) accessibility of CAM services to patients; (4) interaction between team members and patients; (5) perception of CAM/IM; and (6) perception of patient-centered care. Themes underpinning these elements are the following: cultural aspects in conceptualizing IM health care; communication within IM programs; and resource availability for delivering IM services, which impacts patient engagement and team collaboration in the IM framework. CONCLUSIONS: Delivering IM health care requires a model of care that encourages interaction between all stakeholders. Developing a comprehensive conceptual framework to support IM practice is required to facilitate efficient and safe patient care.

Traditional Oriental Herbal Medicine and Natural Killer Cells for Cancer Patients: A Systematic Review and Meta-analysis.

Traditional oriental herbal medicine (HM) is used by cancer patients to improve immunity. Natural killer (NK) cells are associated with development and progression of tumor and survival of cancer patients. This literature review examined randomized controlled trials (RCTs) in four electronic databases until October 2015 to evaluate the effects of oral HM on NK cells in cancer patients. Data were pooled and computed in a meta-analysis. The methodological quality was assessed according to the Cochrane risk of bias tool. Sixteen RCTs involving 1326 cancer patients were identified. Combination of HM and conventional treatment was associated with significantly higher level of NK cells compared with conventional cancer treatments (standardized mean difference, 1.218; 95% confidence interval 0.719-1.717; p < 0.001). Eight RCTs reported statistically significant improvements in the proportions or activity of NK cells in patient groups who received both HM and conventional treatment compared with patients who received conventional treatment alone, while eight RCTs reported no statistically significant differences between the two groups. Studies (n = 16) included in this review had insufficient quality of evidence with unclear (n = 1) and high (n = 15) values of the risk of bias. Although traditional oriental HM may have the positive effects on preserving the level of NK cells in cancer patients receiving conventional treatments, current evidence is inconclusive because of lack of high-quality evidence.

Health and well-being benefits of spending time in forests: systematic review.

BACKGROUND: Numerous studies have reported that spending time in nature is associated with the improvement of various health outcomes and well-being. This review evaluated the physical and psychological benefits of a specific type of exposure to nature, forest therapy. METHOD: A literature search was carried out using MEDLINE, PubMed, ScienceDirect, EMBASE, and ProQuest databases and manual searches from inception up to December 2016. Key words: "Forest" or "Shinrin -Yoku" or "Forest bath" AND "Health" or "Wellbeing". The methodological quality of each randomized controlled trials (RCTs) was assessed according to the Cochrane risk of bias (ROB) tool. RESULTS: Six RCTs met the inclusion criteria. Participants' ages ranged from 20 to 79 years. Sample size ranged from 18 to 99. Populations studied varied from young healthy university students to elderly people with chronic disease. Studies reported the positive impact of forest therapy on hypertension (n = 2), cardiac and pulmonary function (n = 1), immune function (n = 2), inflammation (n = 3), oxidative stress (n = 1), stress (n = 1), stress hormone (n = 1), anxiety (n = 1), depression (n = 2), and emotional response (n = 3). The quality of all studies included in this review had a high ROB. CONCLUSION: Forest therapy may play an important role in health promotion and disease prevention. However, the lack of high-quality studies limits the strength of results, rendering the evidence insufficient to establish clinical practice guidelines for its use. More robust RCTs are warranted.

Randomized controlled trial of Qigong/Tai Chi Easy on cancer-related fatigue in breast cancer survivors.

BACKGROUND: Many breast cancer survivors experience fatigue, mood, and sleep disturbances. PURPOSE: This study aims to compare a meditative movement practice, Qigong/Tai Chi Easy (QG/TCE) with sham Qigong (SQG), testing effects of meditation/breath aspects of QG/TCE on breast cancer survivors' persistent fatigue and other symptoms. METHODS: This double-blind, randomized controlled trial tested 12 weeks of QG/TCE versus SQG on fatigue, depression, and sleep among 87 postmenopausal, fatigued breast cancer survivors, stages 0-III, age 40-75. RESULTS: Fatigue decreased significantly in the QG/TCE group compared to control at post-intervention (p = 0.005) and 3 months follow-up (p = 0.024), but not depression and sleep quality. Improvement occurred over time for both interventions in depression and sleep quality (all p < 0.05). CONCLUSIONS: QG/TCE showed significant improvement over time compared to SQG for fatigue, but not depression or sleep. Both QG/TCE and SQG showed improvement for two prevalent symptoms among breast cancer survivors, depression and sleep dysfunction.

Exploring gender differences in the relationship between gut microbiome and depression - a scoping review.

Background: Major depressive disorder (MDD) exhibits gender disparities, and emerging evidence suggests the involvement of the gut microbiome, necessitating exploration of sex-specific differences. Methods: A review was conducted, encompassing a thorough examination of relevant studies available in Medline via Ovid, Embase via OvidSP, CINAHL, and PsycINFO databases from their inception to June 2023. The search strategy employed specific keywords and Medical Subject Headings (MeSH) terms tailored to major depressive disorder in women, encompassing unipolar depression, depressive symptoms, and dysbiosis. Results: Five studies were included. Among the four studies, alterations in alpha (n=1) and beta diversity (n=3) in the gut microbiome of individuals with MDD were revealed compared to controls. Gender-specific differences were observed in four studies, demonstrating the abundance of specific bacterial taxa and highlighting potential sex-specific implications in MDD pathophysiology. Correlation analyses (n=4) indicated associations between certain bacterial taxa and the severity of depressive symptoms, with varying patterns between males and females. Studies (n=3) also highlighted promising findings regarding the potential utility of microbial markers in diagnosing MDD, emphasizing the crucial role of sex stratification in understanding the disease pathophysiology. Conclusions: The findings underscore the importance of recognizing gender-specific differences in the composition of the gut microbiome and its relationship with MDD. Further comprehensive robust studies are required to unravel the intricate mechanisms underlying these disparities.

Comparison of the clinical effectiveness of treatments for aromatase inhibitor-induced arthralgia in breast cancer patients: A systematic review with network meta-analysis.

Aromatase inhibitor-induced arthralgia (AIA) contributes to poor adherence of aromatase inhibitor therapies in patients with breast cancer. A systematic review using network meta-analysis (NMA) was conducted to examine the clinical effectiveness of multiple therapies and rank probabilities for the management of AIA. Randomized controlled trials (RCTs) assessing treatments for AIA in postmenopausal women with stage 0-III hormone receptor-positive breast cancer were searched from inception to October 2021. The main NMA involved 1516 participants from 17 RCTs. Acupuncture was the highest ranked intervention to improve pain intensity followed by sham acupuncture, multicomponent herbal medicine, exercise, duloxetine, vitamin D, omega-3 fatty acids, physical therapy, testosterone, and inactive controls. Single natural products were inferior to controls. The current review provides new insights into the management of AIA in breast cancer survivors for increased survival and can be utilized to make evidence-based decisions regarding treatment.

Cancer patient disclosure and patient-doctor communication of complementary and alternative medicine use: a systematic review.

OBJECTIVE: To explore the nondisclosure of complementary and alternative medicine (CAM) use among cancer patients, including reasons for and outcomes from nondisclosure of CAM use, within the context of patient-doctor communication. METHOD: A systematic review was conducted exploring investigations surrounding the communication of CAM use for patients with cancer published until August 2011. RESULTS: A total of 21 studies were located, which reported a prevalence of CAM use among patients with cancer ranging between 11% and 95%; of these patients, 20% to 77% did not disclose their CAM use. The main reasons for nondisclosure were the doctor's lack of inquiry; patient's anticipation of the doctor's disapproval, disinterest, or inability to help; and patient's perception that disclosure of CAM use is irrelevant to their conventional care. There is some evidence to suggest that patient-doctor communication about the use of CAM was associated with an enhanced patient-doctor relationship and higher patient satisfaction. CONCLUSIONS: Although the use of CAM by patients with cancer is high, patients frequently fail to disclose its use to their health professionals for reasons emanating from both sides of the dyadic patient-doctor relationship. Because a substantial proportion of patients with cancer may use CAM and there is potential for herb- or vitamin-drug interactions, further research in patient-doctor communication about CAM is necessary to maintain patient safety and wellbeing. The development of effective interventions to improve the disclosure of CAM use should be an integral part of this future research.

Effect of medical Qigong on cognitive function, quality of life, and a biomarker of inflammation in cancer patients: a randomized controlled trial.

PURPOSE: Cancer patients often experience diminished cognitive function (CF) and quality of life (QOL) due to the side effects of treatment and the disease symptoms. This study evaluates the effects of medical Qigong (MQ; combination of gentle exercise and meditation) on CF, QOL, and inflammation in cancer patients. METHODS: Eighty-one cancer patients recruited between October 2007 and May 2008 were randomly assigned to two groups: a control group (n = 44) who received the usual health care and an intervention group (n = 37) who participated in a 10-week MQ program. Self-reported CF was measured by the European Organization for Research and Treatment of Cancer (EORTC-CF) and the Functional Assessment of Cancer Therapy-Cognitive (FACT-Cog). The Functional Assessment of Cancer Therapy-General (FACT-G) was used to measure QOL. C-reactive protein (CRP) was assessed as a biomarker of inflammation. RESULTS: The MQ group self-reported significantly improved CF (mean difference (MD) = 7.78, t (51) = -2.532, p = 0.014) in the EORTC-CF and all the FACT-Cog subscales [perceived cognitive impairment (MD = 4.70, t (43) = -2.254, p = 0.029), impact of perceived cognitive impairment on QOL (MD = 1.64, t (45) = -2.377, p = 0.024), and perceived cognitive abilities (MD = 3.61, t (45) = -2.229, p = 0.031)] compared to controls. The MQ group also reported significantly improved QOL (MD = 12.66, t (45) = -5.715, p < 0.001) and had reduced CRP levels (MD = -0.72, t (45) = 2.092, p = 0.042) compared to controls. CONCLUSIONS: Results suggest that MQ benefits cancer patients' self-reported CF, QOL, and inflammation. A larger randomized controlled trial including an objective assessment of CF is planned.

An Innovative Tai Chi and Qigong Telehealth Service in Supportive Cancer Care During the COVID-19 Pandemic and Beyond.

Supportive cancer care services, including acupuncture and Tai Chi and Qigong (TQ), are offered to cancer patients to manage cancer symptoms and/or treatment-related adverse effects and improve quality of life during and after standard care. Normal face-to-face acupuncture and TQ group services were suspended during the coronavirus (COVID-19) pandemic to reduce the risk of transmission of infection and meet social distancing restriction guidelines. This led to a sudden shift from face-to-face sessions to telehealth sessions in the health care system. We report patients' experiences of TQ telehealth services as a new initiative developed for cancer care. We found that delivery of TQ telehealth is feasible and resulted in increased overall patient satisfaction with cancer care services during the lockdown. The delivery of TQ telehealth experiences and challenges are discussed.

The Gut Microbiome and Gastrointestinal Toxicities in Pelvic Radiation Therapy: A Clinical Review.

BACKGROUND: Gastrointestinal (GI) toxicities are common adverse effects of pelvic radiotherapy (RT). Several recent studies revealed that toxicity of RT is associated with dysbiosis of the gut microbiome. METHOD: A literature search was conducted in electronic databases Medline, PubMed, and ScienceDirect, with search terms "microbiome and/or microbiota" and "radiotherapy (RT) and/or chemoradiation therapy (CRT)" and "cancer", and the relevant literature were selected for use in this article. RESULTS: Eight prospective cohort studies were selected for review with a total of 311 participants with a range of 15-134 participants within these studies. The selected studies were conducted in patients with gynaecological (n = 3), rectal (n = 2), or prostate cancers (n = 1), or patients with various types of malignancies (n = 2). Three studies reported that cancer patients had significantly lower alpha diversity compared with healthy controls. Seven studies found that lower alpha diversity and modulated gut microbiome were associated with GI toxicities during and after pelvic RT (n = 5) and CRT (n = 2), whereas one study found that beta diversity was related to a complete response following CRT. Two further studies reported that fatigue was associated with dysbiosis of the gut microbiome and low alpha diversity during and after RT, and with dysbiosis of the gut microbiome and diarrhoea, respectively. CONCLUSION: Gut microbiome profiles are associated with GI toxicities and have the potential to predict RT/CRT-induced toxicities and quality of life (QoL) in patients undergoing those treatments. Further robust randomized controlled trials (RCTs) are required to elucidate the effect of gut microbiome profiles on RT-related adverse effects and responses to RT.

The Gut Microbiome and Cancer Immunotherapy: Can We Use the Gut Microbiome as a Predictive Biomarker for Clinical Response in Cancer Immunotherapy?

Background: Emerging evidence suggests that gut microbiota influences the clinical response to immunotherapy. This review of clinical studies examines the relationship between gut microbiota and immunotherapy outcomes. Method: A literature search was conducted in electronic databases Medline, PubMed and ScienceDirect, with searches for "cancer" and "immunotherapy/immune checkpoint inhibitor" and "microbiome/microbiota" and/or "fecal microbiome transplant FMT". The relevant literature was selected for this article. Results: Ten studies examined patients diagnosed with advanced metastatic melanoma (n = 6), hepatocellular carcinoma (HCC) (n = 2), non-small cell lung carcinoma (NSCLC) (n = 1) and one study examined combination both NSCLC and renal cell carcinoma (RCC) (n = 1). These studies consistently reported that the gut microbiome profile prior to administering immune checkpoint inhibitors (ICIs) was related to clinical response as measured by progression-free survival (PFS) and overall survival (OS). Two studies reported that a low abundance of Bacteroidetes was associated with colitis. Two studies showed that patients with anti-PD-1 refractory metastatic melanoma experienced improved response rates and no added toxicity when receiving fecal microbiota transplant (FMT) from patients with anti-PD-1 responsive disease. Conclusions: Overall, significant differences in the diversity and composition of the gut microbiome were identified in ICIs responders and non-responders. Our findings provide new insights into the value of assessing the gut microbiome in immunotherapy. Further robust randomized controlled trials (RCTs) examining the modulatory effects of the gut microbiome and FMT on ICIs in patients not responding to immunotherapy are warranted.

Emerging Evidence of the Gut Microbiome in Chemotherapy: A Clinical Review.

Increasing evidence suggests that the gut microbiome is associated with both cancer chemotherapy (CTX) outcomes and adverse events (AEs). This review examines the relationship between the gut microbiome and CTX as well as the impact of CTX on the gut microbiome. A literature search was conducted in electronic databases Medline, PubMed and ScienceDirect, with searches for "cancer" and "chemotherapy" and "microbiome/microbiota". The relevant literature was selected for use in this article. Seventeen studies were selected on participants with colorectal cancer (CRC; n=5), Acute Myeloid Leukemia (AML; n=3), Non-Hodgkin's lymphoma (n=2), breast cancer (BCa; n=1), lung cancer (n=1), ovarian cancer (n=1), liver cancer (n=1), and various other types of cancers (n=3). Seven studies assessed the relationship between the gut microbiome and CTX with faecal samples collected prior to (n=3) and following CTX (n=4) showing that the gut microbiome is associated with both CTX efficacy and toxicity. Ten other prospective studies assessed the impact of CTX during treatment and found that CTX modulates the gut microbiome of people with cancer and that dysbiosis induced by the CTX is related to AEs. CTX adversely impacts the gut microbiome, inducing dysbiosis and is associated with CTX outcomes and AEs. Current evidence provides insights into the gut microbiome for clinicians, cancer survivors and the general public. More research is required to better understand and modify the impact of CTX on the gut microbiome.

The Effects of Acupuncture on Cancer-Related Fatigue: Updated Systematic Review and Meta-Analysis.

BACKGROUND: Several studies have identified fatigue as one of the major symptoms experienced during and after cancer treatment. However, there are limited options to manage cancer related fatigue (CRF) with pharmacological interventions. Several acupuncture studies suggested that acupuncture has a positive impact on CRF. This review aims to assess the evidence of acupuncture for the treatment of CRF. METHOD: Electronic database searches were conducted on 4 English databases (Medline, PubMed, Embase, and ScienceDirect). Search keywords were; "acupuncture" and "cancer," or "cancer related fatigue." Studies published as full text randomized controlled trials (RCTs) in English were included. Estimates of change in fatigue cores were pooled using a random effects meta-analysis where randomized comparisons were available for true acupuncture versus sham acupuncture and true acupuncture versus usual care. The quality of original papers were assessed using the Cochrane Collaboration's tool for assessing risk of bias (ROB). RESULTS: Nine RCTs were selected for review with a total of 809 participants and a range of 13 to 302 participants within the studies. Six RCTs reported significant improvement of CRF for the acupuncture intervention compared to the control groups. Pooled estimates suggest Brief Fatigue Inventory scores are 0.93 points lower 95% CI (-1.65, -0.20) in true acupuncture versus sham acupuncture and 2.12 points lower 95% C (-3.21, -1.04) in true acupuncture versus usual care. Six studies had low risk of bias (ROB) and 3 studies had a moderate ROB predominantly in blinding of participants, blinding of assessors and incomplete data outcomes. Among the 9 RCTs, 2 studies have reported the occurrence of minor adverse effects (spot bleeding and bruising) related to acupuncture treatment. No serious adverse reactions related to acupuncture were reported. CONCLUSION: The current literature review suggests that acupuncture has therapeutic potential in management of CRF for cancer survivors. Promotion of acupuncture in cancer care to manage CRF may improve the quality of life of cancer survivors.

The Effects of Tai Chi and Qigong on Immune Responses: A Systematic Review and Meta-Analysis.

Background: Effective preventative health interventions are essential to maintain well-being among healthcare professionals and the public, especially during times of health crises. Several studies have suggested that Tai Chi and Qigong (TQ) have positive impacts on the immune system and its response to inflammation. The aim of this review is to evaluate the current evidence of the effects of TQ on these parameters. Methods: Electronic searches were conducted on databases (Medline, PubMed, Embase and ScienceDirect). Searches were performed using the following keywords: "Tai Chi or Qigong" and "immune system, immune function, immunity, Immun*, inflammation and cytokines". Studies published as full-text randomized controlled trials (RCTs) in English were included. Estimates of change in the levels of immune cells and inflammatory biomarkers were pooled using a random-effects meta-analysis where randomised comparisons were available for TQ versus active controls and TQ versus non-active controls. Results: Nineteen RCTs were selected for review with a total of 1686 participants and a range of 32 to 252 participants within the studies. Overall, a random-effects meta-analysis found that, compared with control conditions, TQ has a significant small effect of increasing the levels of immune cells (SMD, 0.28; 95% CI, 0.13 to 0.43, p = 0.00), I2 = 45%, but not a significant effect on reducing the levels of inflammation (SMD, -0.15; 95% CI, -0.39 to 0.09, p = 0.21), I2 = 85%, as measured by the systemic inflammation biomarker C-reactive protein (CRP) and cell mediated biomarker cytokines. This difference in results is due to the bidirectional regulation of cytokines. An overall risk of bias assessment found three RCTs with a low risk of bias, six RCTs with some concerns of bias, and ten RCTs with a high risk of bias. Conclusions: Current evidence indicates that practising TQ has a physiologic impact on immune system functioning and inflammatory responses. Rigorous studies are needed to guide clinical guidelines and harness the power of TQ to promote health and wellbeing.

Physical and Psychological Health Outcomes of Qigong Exercise in Older Adults: A Systematic Review and Meta-Analysis.

Physical limitations, depression and anxiety are prevalent among older adults. Mild to moderate exercise can promote physical and psychological health and reduce the risk of chronic diseases. Qigong, a type of Chinese traditional medicine exercise, has demonstrated beneficial effects on physical ability and mental health in adults with chronic conditions. The purpose of this review was to systematically assess the effects of Qigong exercise on physical and psychological health outcomes in older adults. A total of 1282 older adults aged 62 to 83 years with depressive symptoms, frailty or chronic medical illnesses were included in this review. The meta-analysis showed that Qigong exercise resulted in significantly improved physical ability compared with active control or usual care (standardized mean difference [SMD]  =  1.00 and 1.20, respectively). The pooled effects of studies with thrice weekly Qigong sessions had the greatest effect ( SMD=1.65 ) on physical ability in older adults. Lower quality studies demonstrated larger effect sizes than those of higher quality. Although Qigong exercise showed favorable effects on depression, balance and functioning, the overall effects did not reach statistical significance. No significant adverse events were reported. The findings suggest that the Qigong exercise may be an option for older adults to improve physical ability, functional ability, balance and to lessen depression and anxiety. However, the number of RCTs that enroll older adults is limited. More methodologically sound RCTs are needed to confirm the efficacy of Qigong exercise on physical and psychological health in older adults with chronic illnesses.

Medical Qigong for cancer patients: pilot study of impact on quality of life, side effects of treatment and inflammation.

Quality of life (QOL) of cancer patients is often diminished due to the side effects of treatment and symptoms of the disease itself. Medical Qigong (coordination of gentle exercise and relaxation through meditation and breathing exercise based on Chinese medicine theory of energy channels) may be an effective therapy for improving QOL, symptoms and side effects, and longevity of cancer patients. In this pilot study, the feasibility, acceptability, and impact of Medical Qigong (MQ) were evaluated on outcomes in cancer patients. Thirty patients diagnosed with heterogeneous cancers, were randomly assigned to two groups: a control group that received usual medical care and an intervention group who participated in a MQ program for 8 weeks in addition to receiving usual medical care. Randomization was stratified by completion of cancer treatment (n = 14) or under chemotherapy (n = 16). Patients completed measures before and after the program. Quality of life and symptoms were measured by the EORTC QLQ-C 30 and progress of disease by the inflammation biomarker (CRP: c-reactive protein) via a blood test was assessed. The MQ intervention group reported clinically significant improved global QOL scores pre- and post-intervention. The MQ intervention also reduced the symptoms of side effects of cancer treatment and inflammation biomarker (CRP) compare to the control group. Due to the small sample size, however, the results were not statistically significant between treatment and the control groups. Data from the pilot study suggest that MQ with usual medical treatment can enhance the QOL of cancer patients and reduce inflammation. This study needs a further investigation with a larger sample size.

Treatment of Sciatica Following Uterine Cancer with Acupuncture: A Case Report.

For women, gynaecological or obstetrical disorders are second to disc prolapse as the most common cause of sciatica. As not many effective conventional treatments can be found for sciatica following uterine cancer, patients may seek assistance from complementary and alternative medicine. Here, we present a case of a woman with severe and chronic sciatica secondary to uterine cancer who experienced temporary relief from acupuncture.
