Effects of Mindfulness-Based Therapy for Cancer Patients: A Systematic Review and Meta-analysis

eHealth mindfulness-based music therapy for patients undergoing allogeneic hematopoietic stem cell transplantation: A pilot randomized controlled trial protocol

BACKGROUND

Allogeneic stem cell transplantation (allo-SCT) is the preferred therapy for patients with high-risk or relapsed hematologic malignancies, but may be complicated by psychological distress (e.g., depression, anxiety) and symptom burden (e.g., fatigue, pain). Mindfulness-based music therapy (MBMT), a relatively novel integrative medicine intervention that draws from mindfulness and music therapy principles, has shown promise in improving psychosocial outcomes and symptom burden in cancer patients. We outline an eHealth-based MBMT (eMBMT) intervention protocol examining: (1) feasibility, acceptability, and intended effects of eMBMT in improving HRQOL, symptom burden, and clinical markers of disease activity (e.g., infections), and (2) the extent to which eMBMT music therapy component-associated improvements in HRQOL, symptom burden, and disease activity are mediated by improvements in psychosocial and physiological (e.g., systemic inflammation, immune recovery) adaptation.

METHODS

Participants (n = 60) with a hematologic malignancy undergoing allo-SCT will be randomized to receive eMBMT or an eHealth-based mindfulness meditation (eMM) intervention. eMBMT includes eight 60-min sessions facilitated by a music therapist focusing on mindfulness and music therapy. eMM includes eight 60-min self-led MM practices.

RESULTS

Feasibility, acceptability, HRQOL, symptom burden, disease activity, and mediation effects of psychosocial and physiological adaptation will be assessed at baseline, pre-infusion, and post-engraftment with blood collection at baseline and post-engraftment.

CONCLUSION

The current pilot RCT is the first eMBMT intervention to address the HRQOL and symptom burden of patients who are undergoing allo-SCT. Results will inform a fully powered RCT to establish preliminary efficacy of eMBMT on improvements in HRQOL, symptom burden, and disease activity.

A perspective on a precision approach to pain in cancer; moving beyond opioid therapy

PURPOSE

Cancer-related pain is primarily treated with opioids which while effective can add significant patient burden due to side effects, associated stigma, and timely access. The purpose of this perspective discussion is to argue for a precision approach to pain in cancer based on a biopsychosocial and spiritual model which we argue can offer a higher quality of life while limiting opioid use.

CONCLUSIONS

Pain in cancer represents a heterogenous process with multiple contributing and modulating factors. Specific characterization of pain as either nociceptive, neuropathic, nociplastic, or mixed can allow for targeted treatments. Additional assessment of biopsychosocial and spiritual issues can elucidate further points of targeted intervention which can lead to overall greater pain control.

The Effects of Complementary Therapies on Patient-Reported Outcomes: An Overview of Recent Systematic Reviews in Oncology

Many patients with cancer make use of complementary medicine alongside conventional medicine, but clinicians in oncology often lack the knowledge to adequately advise patients on the evidence base for complementary therapies. This study aims to provide an overview of recently published systematic reviews that assess the effects of complementary therapies on patient-reported health outcomes in patients with cancer. Systematic reviews, including a meta-analysis of at least two randomized controlled trials, were identified from the PubMed, Embase, Cochrane Library, CINAHL and PsycINFO databases. The methodological quality was assessed with AMSTAR 2. One hundred systematic reviews were included. The results suggest that several complementary therapies can improve health outcomes reported by patients with cancer, such as acupuncture to relieve pain, music interventions to reduce anxiety and yoga to improve cancer-related fatigue. The side effects related to complementary therapy use are generally mild. The results remain inconclusive for some intervention-outcome combinations. Many of the included systematic reviews insufficiently assessed the causes and impact of bias in their interpretation of the results. This overview of systematic reviews can support clinicians in counselling their patients on this topic and provide directions for future research and clinical practice guidelines in the field of complementary medicine.

Effects of online mindfulness-based interventions (MBIs) on anxiety symptoms in adults: a systematic review and meta-analysis

BACKGROUND

An increasing number of studies have documented the effectiveness on various types of face-to-face and online mindfulness-based interventions (MBIs) in reducing anxiety among general population, but there is a scarcity of systematic reviews evaluating evidence of online MBIs on anxiety in adults. Therefore, we examined the effects of online mindfulness-based interventions (MBIs) on anxiety symptoms in adults and explored the moderating effects of participant, methods, and intervention characteristics.

METHODS

We systematically searched nine databases through May 2022 without date restrictions. Inclusion criteria were primary studies evaluating online mindfulness-based interventions with adults with anxiety measured as an outcome, a comparison group, and written in English. We used random-effects model to compute effect sizes (ESs) using Hedges' g, a forest plot, and Q and I² statistics as measures of heterogeneity; we also examined moderator analyses.

RESULTS

Twenty-six primary studies included 3,246 participants (39.9 ± 12.9 years old). Overall, online mindfulness-based interventions showed significantly improved anxiety (g = 0.35, 95%CI 0.09, 0.62, I² = 92%) compared to controls. With regards to moderators, researchers reported higher attrition, they reported less beneficial effects on anxiety symptoms (β=-0.001, Q_model=4.59, p = .032). No other quality indicators moderated the effects of online mindfulness-based interventions on anxiety.

CONCLUSION

Online mindfulness-based interventions improved anxiety symptoms in adult population. Thus, it might be used as adjunctive or alternative complementary treatment for adults. However, our findings must be interpreted with caution due to the low and unclear power of the sample in primary studies; hence, high-quality studies are needed to confirm our findings.

The Impact of Mindfulness on Functional Brain Connectivity and Peripheral Inflammation in Breast Cancer Survivors with Cognitive Complaints

BACKGROUND

Cancer-related cognitive impairment (CRCI) has been linked to functional brain changes and inflammatory processes. Hence, interventions targeting these underlying mechanisms are needed. In this study, we investigated the effects of a mindfulness-based intervention on brain function and inflammatory profiles in breast cancer survivors with CRCI.

METHODS

Female breast cancer survivors reporting cognitive complaints (n = 117) were randomly assigned to a mindfulness-based intervention (n = 43), physical training (n = 36), or waitlist control condition (n = 38). Region-of-interest (ROI) and graph theory analyses of resting state functional MRI data were performed to study longitudinal group differences in functional connectivity and organization in the default mode, dorsal attention, salience, and frontoparietal network. Additionally, bead-based immunoassays were used to investigate the differences in inflammatory profiles on serum samples. Measures were collected before, immediately after and three months post-intervention.

RESULTS

No ROI-to-ROI functional connectivity changes were identified. Compared to no intervention, graph analysis showed a larger decrease in clustering coefficient after mindfulness and physical training. Additionally, a larger increase in global efficiency after physical training was identified. Furthermore, the physical training group showed a larger decrease in an inflammatory profile compared to no intervention (IL-12p70, IFN-γ, IL-1β, and IL-8).

CONCLUSION

Both mindfulness and physical training induced changes in the functional organization of networks related to attention, emotion processing, and executive functioning. While both interventions reduced functional segregation, only physical training increased functional integration of the neural network. In conclusion, physical training had the most pronounced effects on functional network organization and biomarkers of inflammation, two mechanisms that might be involved in CRCI.

Coping After Breast Cancer (CABC): Protocol for a randomized controlled trial of stress management e-health interventions

BACKGROUND

One-third or more of breast cancer survivors report stress and other psychological and physical complaints that can negatively impact quality of life. Psychosocial stress-management interventions, shown to mitigate the negative impact of these complaints, can now be delivered as accessible and convenient (for the patient and provider) e-health interventions. In the present randomized controlled trial (RCT), Coping After Breast Cancer (CABC), two modified versions of the stress management e-health intervention program StressProffen were created: one with predominantly cognitive-behavioral stress-management content (Stressproffen-CBI) and one with predominantly mindfulness-based stress-management content (StressProffen-MBI).

OBJECTIVE

To investigate the effects in breast cancer survivors of using StressProffen-CBI and StressProffen-MBI compared to a control group (treatment as usual).

METHODS

Women diagnosed with breast cancer (stage I-III, unequivocally HER2+ or ER- tumors) or DCIS aged 21-69 years who completed the Cancer Registry of Norway- initiated health survey on quality of life, are invited to the CABC trial about seven months after diagnosis. Women who give consent to participate are randomized (1:1:1) to: Stressproffen-CBI, Stressproffen-MBI, or control group. Both Stressproffen interventions consist of 10 modules of stress management content delivered through text, sound, video, and images. The primary outcome is between-groups changes in perceived stress at six months, assessed with Cohen's Perceived Stress Scale. Secondary outcomes comprise changes in quality of life, anxiety, depression, fatigue, sleep, neuropathy, coping, mindfulness and work-related outcomes approximately 1, 2 and 3 years after diagnosis. Long-term effects of the interventions on work participation, comorbidities, relapse or new cancers and mortality will be obtained from national health registries.

RESULTS

We plan to recruit 430 participants in total (100 in each group). Recruitment is scheduled from January 2021 through May 2023.

CONCLUSIONS

The CABC trial is possibly the largest ongoing psychosocial e-health RCT in breast cancer patients at current. If one or both interventions prove to be effective in reducing stress and improving psychosocial and physical complains, the StressProffen e-health interventions could be beneficial, inexpensive, and easily implementable tools for breast cancer survivors when coping with late effects after cancer and cancer treatments.

The mediating effect of mindfulness on demoralization syndrome and quality of life of thyroid cancer patients: A correlational study

Demoralization syndrome is prevalence among cancer patients in China. However, little research has examined how demoralization syndrome is associated with quality of life (QOL). The aims of this study were to investigate the relationship between mindfulness state, demoralization syndrome and QOL of thyroid cancer patients, and explore the mediating effect of mindfulness on demoralization syndrome and QOL. A correlational cross-sectional study was performed using an online questionnaire. The study was conducted from July to October 2022 among 310 thyroid cancer patients. General information questionnaire, the Demoralization Scale, Five Facet Mindfulness Questionnaire, short form health survey questionnaire were used for investigation. Calculations were performed using SPSS Statistics, version 25. Descriptive statistics, correlation, and process plug-in mediation effect analyses were used to analyze the data. A total of 310 valid questionnaires were finally recovered. The Five Facet Mindfulness Questionnaire score of 310 patients was (120.80 ± 16.57), Demoralization Scale score was (12.49 ± 4.73), short form health survey questionnaire score was (146.15 ± 28.46). Mindfulness played a partial mediating role between demoralization syndrome and QOL of thyroid cancer patients, and the mediating effect accounted for 68.57% of the total effect. Demoralization syndrome can influence QOL through mindfulness state. Measures are needed to increase the QOL of thyroid cancer patients by developing mindfulness programs to decrease their demoralization syndrome.

Effects of Mindfulness-Based Interventions on Depression in Patients With Breast Cancer: A Systematic Review and Meta-Analysis

OBJECTIVE

We examined the effects of Mindfulness-based interventions (MBIs) on depressive symptoms in women with breast cancer and examined the moderating effects of participant characteristics, research methodologies, and features of interventions.

METHODS

We systematically searched 12 databases through November 2022 without date restrictions using the following search terms: (mindful* or meditation) AND (cancer OR neoplasm) AND (depress*). Studies included were primary studies evaluating MBIs in women with breast cancer who also had depression. Studies were included if they used a control group and were written in English. We used a random-effects model to compute effect sizes (ESs) using Hedges' g, forest plot, and Q and I2 statistics as measure of heterogeneity. We also requested moderator analyses.

RESULTS

We found 19 studies with 2139 participants (49.4 ± 8.3 years old) that met inclusion criteria for this meta-analysis and systematic review. Overall, women in MBI groups demonstrated significantly lower levels of depression (g = 0.48, 95% CI:0.159, 0.792, P < .001) compared to women in control groups. Regarding moderators, providing MBIs with a home assignment component showed a significantly greater effect on decreasing depressive symptoms (g = 1.75) compared to MBIs without a home assignment component (g = 0.20). When researchers used concealed allocation technique, the interventions demonstrated lower effects on depression than when concealed allocation (g = 0.11vs g = 1.33, P ≤ .001) was not reported. Additionally, when researchers reported high rates of sample attrition, they found a lower effect size on depression (β = -.019, Q = 3.97, P = .046) indicating that attrition moderates the effect.

CONCLUSION

MBIs are moderately effective interventions to reduce depressive symptoms among women with breast cancer. Clinicians might consider encouraging MBIs as adjunct/alternative treatments for women with breast cancer to manage symptoms of depression. Interventions that incorporat home assignments for practicing mindfulness are likely to have a greater effect on reducing depressive symptoms. Additionally, methods including concealed allocation and attrition rate were moderators of the effects of MBIs on depression in women with breast cancer.
