Efficacy of Mindfulness-Based Cognitive Therapy on Late Post-Treatment Pain in Women Treated for Primary Breast Cancer: A Randomized Controlled Trial

Psychological Intervention for Patients with Biopsychosocial Late Effects Following Surgery for Colorectal Cancer with Peritoneal Metastases-A Feasibility Study

Background: Up to 80% of patients experience late effects (LE) one year after surgery for peritoneal metastases (PM) from colorectal cancer (CRC). We tested the feasibility and outcome of a treatment strategy to address LEs. Methods: During January 2021-May 2023, patients who had undergone surgery for CRC-PM in Denmark were screened for biopsychosocial LEs (anxiety, depression, fear of cancer recurrence, insomnia, cognitive impairment, pain, fatigue). Patients scoring according to clinical cut-offs were referred to a Multi-Disciplinary Team conference (MDT). The patients, surgeon(s), nurse(s), and psychologists participated in the MDT, identified key concerns and proposed a personalized intervention. Pre- and post-intervention, patients completed a "Measure Yourself Concerns and Wellbeing" (MYCaW) questionnaire, rating the two most distressing LEs and general wellbeing on a 7-point Likert scale. Results: Of 28 eligible patients, 13 (59 years (mean), 85% women) accepted referral, participated in the MDT, and were offered a personalized intervention. The intervention was completed by 11 patients. Improvement in MYCaW score was observed 1 month postintervention for all three items: (1) the primary LE (p = 0.003, Hedges's g 1.54), (2) the secondary LE (p < 0.001, Hedges's g 1.65), and (3) general wellbeing (p = 0.005, Hedges's g 1.09). This improvement was sustained 6 months postintervention. The 15 non-participants were, in general, older (66 years (mean), men 73%). Conclusions: Screening for LEs and conducting an MDT can provide a personalized intervention plan, which patients are able to complete and may benefit from.

Mindfulness-based psychosocial interventions and psychological wellbeing in cancer survivorship: a meta-analysis

PURPOSE

Among cancer survivors, mindfulness-based interventions appear promising in decreasing distress for cancer patients, but little attention has been paid to the ultimate mindfulness goal of increasing psychological wellbeing. This meta-analysis aims to summarise and synthesise available evidence concerning the effectiveness of MBIs on positive psychological outcomes reflecting key aspects of psychological wellbeing in heterogeneous cancer patients.

METHODS

A literature search of mindfulness-based randomised clinical trials in cancer survivors was conducted across six electronic databases. Two reviewers independently screened studies and extracted data. Meta-analyses were conducted using R; standardised mean difference (SMD) was used to determine intervention effect. Moderators examined included therapeutic orientation, control group type, treatment modality, treatment target, heterogeneous vs. homogeneous cancer type, and facet of wellbeing.

RESULTS

Thirty-one studies were included (N = 2651). Those who received mindfulness-based interventions reported significantly higher eudaimonic, hedonic, and social wellbeing than respondents in control groups (SMD = 0.599). Interventions were equally effective across therapeutic orientation, control group type, treatment modality and treatment target. There were trend level differences favouring homogeneous cancer diagnosis groups over heterogeneous diagnosis groups.

CONCLUSION

MBIs provide an effective treatment for increasing psychological wellbeing in cancer survivors. This finding has important implications for clinical practice.

Positive health outcomes of mindfulness-based interventions for cancer patients and survivors: A systematic review and meta-analysis

Mindfulness-based interventions (MBIs) are commonly used for cancer patients and survivors to reduce symptoms, but little is known about effects on positive health outcomes. We conducted a systematic review and meta-analysis to determine the effects of MBIs on positive health outcomes (mindfulness skills, self-compassion, positive affect, coping, social support, well-being, personal growth, and spirituality) in cancer patients and survivors. Four databases (PubMed, PsycINFO, Web of Science, and CINAH) were searched (grey literature was not included), abstracts and full texts were screened, and MBI quality and risk of bias were assessed. Effect sizes were calculated and data was analyzed using a frequentist analytical strategy. Eligible studies were randomized controlled trials (RCTs) evaluating the effect of MBIs compared to any type of control on positive health outcomes in cancer patients or survivors. Based on 46 RCTs eligible for meta-analysis, statistical significant effects were observed for all positive health outcomes at post-treatment. Effect sizes ranged from small (positive affect; Hedges's g = 0.26) to large (spirituality, g = 0.91). At follow-up, mindfulness skills, self-compassion, personal growth, and spirituality reached statistical significance, with effect sizes ranging from small (positive affect; g = 0.07) to medium (spirituality; g = 0.61) and large (post-traumatic growth; g = 1.40). Taken together, significant effects of MBIs were found for several positive outcomes in cancer patients and survivors, with the strongest evidence found for mindfulness skills. MBIs may play a key role in improving well-being in this population.

Meditation-Based Therapies for Chronic Neuropathy: A Systematic Review and Meta-Analysis

Mind-body therapies have been found to be effective in a variety of pathologies. The purpose of this study was to evaluate the efficacy of meditation-based therapies in relieving the symptoms severity, quality of life, stress and other associated mood conditions, in individuals with chronic neuropathy of various etiologies. A systematic review of randomized controlled trials, involving adult patients with persistent peripheral neuropathy, was performed. Seven article databases were searched. A meta-analysis was conducted to assess the benefits of meditation-based therapy on symptomatology, quality of life, anxiety, depression, perceived stress, sleep quality and mindfulness score. Ten of the 1133 reviewed papers were selected for quantitative review. The meditation group had a lower standardized mean difference (SMD) score (-0.47 (95% CI: -0.97 to 0.02), p=0.062) for neuropathic pain severity score; lower anxiety scores (-2.5 (95% CI: -3.68 to -1.32), p=<0.001); lower depression scores (-1.53 (95% CI: -2.12 to -0.93), p=<0.001); lower perceived stress (-1.06 (95% CI: -3.15 to 1.04), p=0.323); higher quality of life scores (2.19 (95% CI: -0.65 to 5.03), p=0.13); lower sleep quality scores (-1.27 (95% CI: -4.22 to 1.67), p=0.397); higher mindfulness scores (6.71 (95% CI: 4.09 to 9.33), p=<0.001); and lower pain severity at 1 to 1.5 follow up (-1.75 (95% CI: -2.98 to -0.51), p=0.006). Some of the results were characterized by a substantial, statistically significant heterogeneity. Nevertheless, a major part of the results pointed in the same direction, improving symptomatology with meditation-based therapy. The studies had a risk of bias mostly regarding the measurement of the outcome, randomization process and selection of the reported result. The current study discovered that the meditation group had significantly lower pain (at 1 to 1.5 months follow-up) anxiety, and depression scores and higher mindfulness scores at the end of the interventions.

The Effect of Art Therapy on Pain, Emesis, Anxiety, and Quality of Life in Operated Breast Cancer Patients: Randomized Control Trials

Background: Breast cancer symptoms related to the disease nature and treatments develop and the quality of life of patients is impacted. Art therapy improves the quality of life by increasing symptom control and treatment compliance. This study aimed to determine the effect of art therapy on pain, emesis, anxiety, and quality of life in operated breast cancer patients. Methods: This experimental research was carried out with a total of 60 patients, 30 in the intervention group (IG) and 30 in the control group (CG), who received treatment in the Oncology Center of Sivas Cumhuriyet University Practice and Research Hospital. A Personal Information Form, the Pain Intensity-Visual Analog Scale, the Rhodes Index of Nausea, Vomiting, and Retching, the Beck Anxiety Inventory, and the Functional Assessment of Cancer Therapy Scale-General (FACT-G) were used to collect research data. Within the scope of the research, IG received chemotherapy sessions for 10 weeks (five sessions) with 2-week intervals by an art specialist in marbling, accompanied by ney music. CG received no intervention. The obtained data were uploaded to the SPSS (22.0) program and statistical analysis was performed. Results: The decrease in the pain, nausea-vomiting, and anxiety levels of the patients in IG and the increase in their quality of life after the art therapy accompanied by ney music were statistically significant compared with the first follow-up (p < 0.05). There was no statistically significant change in the quality of life of the patients in the CG, whereas their pain, nausea-vomiting, and anxiety scores increased. According to the comparison between IG and CG, there was a significant difference in favor of IG in terms of pain severity, quality of life, emesis, and anxiety levels (p < 0.05). Conclusions: The art of marbling with ney was effective in operated breast cancer patients experiencing pain, emesis, and anxiety and improved their quality of life. Clinical Trial Registration: NCT05666583.

Mindfulness intervention effect on endometriosis-related pain dimensions and its mediator role on stress and vitality: a path analysis approach

Endometriosis-related pain is supposedly mainly responsible for generating psychological stress and deteriorating the quality of life. However, the interaction between these factors has not been investigated, considering its multidimensional nature and through the path of effects of psychosocial approaches. The present study aims to investigate the effect of a brief mindfulness-based intervention (bMBI) on pain dimensions and its mediator role on psychological stress and QoL-Vitality improvement. A secondary analysis of a pilot randomized controlled trial using a series of parallel and serial mediators was carried out. The results showed that bMBI improves the sensory (B = -6.09 [-9.81, -2.52], β = -0.42) and affective (B = -3.40 [-5.02, -1.80], β = -0.47) pain. The bMBI effect on psychological stress reduction was mediated by these changes in sensory (B = -2.81 [-6.06, -0.41], β = -0.21) and affective (B = -1.97 [-5.07, -0.17], β = -0.15) pain. Serial sensory pain and psychological stress reduction (B = 2.27 [0.11, 5.81], β = -0.09) mediated the bMBI effect on quality of life vitality. Meditation training promotes additional improvement in affective and sensory pain characteristics through which psychological stress is reduced. The sensory pain dimension must be positively impacted in combination with psychological stress for the bMBI improves women's vitality. Adding a psychosocial intervention like meditation training to the standard treatment plan may be required for some women to achieve the needed changes to restore well-being.

Mindfulness-based therapies for cancer patients and families: a systematic review

BACKGROUND

Mindfulness-based therapies (MBTs) addressed to patients with cancer have been widely studied in the last two decades, and their efficacy has been systematically reviewed and meta-analysed. Although findings from literature highlight benefits of MBTs on several patients' health outcomes, these should be appraised taking into consideration the characteristics of the selected studies. In this systematic review, we summarised the current evidence of the efficacy of MBTs in improving the quality of life of both patients with cancer and their relatives, with a focus on the methodological quality, type of MBT evaluated and population involved in existing randomised controlled trials (RCTs).

METHODS

We searched English language articles published until February 2021. Couples of authors independently applied inclusion criteria and extracted findings. Thirty RCTs were included.

RESULTS

Nearly half of the studies were performed in English-speaking countries outside of Europe, with females diagnosed with breast cancer. Most considered heterogeneous phases of illness; one study only was performed on relatives. In most cases, different measures were employed to evaluate the same outcome. The efficacy of MBTs has been demonstrated in 25 of the 30 included articles. The methodological quality of RCTs was acceptable.

CONCLUSION

The heterogeneity of studies' characteristics makes findings on the efficacy of MBTs poorly informative with reference to different clinical and cancer-related psychological conditions. Studies on more homogeneous samples by cancer site and phase, as well as performed in different cultural contexts, could provide a basis for better evaluating and targeting MBTs' protocols for the specific needs of patients with cancer and their relatives.

Psychological distress and coping strategies in breast cancer patients under neoadjuvant therapy: A systematic review

BACKGROUND

During neoadjuvant therapy (NAT), patients with locally advanced breast cancer (LABC) experience psychological distress (PD) and adopt appropriate coping strategies.

OBJECTIVE

This systematic review aimed to examine the prevalence and changes in PD and coping strategies in patients with LABC during NAT and to evaluate effective interventions to reduce their PD.

DESIGN

Quantitative (cross-sectional, longitudinal, and interventional) and qualitative studies reporting PD and coping strategies related to NAT during LABC were included.

DATA SOURCES AND METHODS

PubMed, Cochrane Library, Scopus, ScienceDirect, Wiley Online Library, and Web of Science databases were consulted to gather relevant literature from the first publications until July 25, 2023. Selection was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

RESULTS

A total of 41 articles were included, of which four were qualitative. The main results showed that the prevalence of depression before NAT ranged from 0% to 46% and that of anxiety from 5.5% to 54%. After NAT, the prevalence of depression ranged from 40% to 78.5% and anxiety accounted for 27%. Additionally, PD decreased during NAT. The main determinants of PD were perceived social support, living in joint families, being affected by COVID-19 infection, delays in diagnosis, and starting neoadjuvant treatment. For coping strategies, after NAT, "resigned coping" decreased, whereas "social support" increased, and active coping strategies were correlated with better PD. Some interventions found a reduction in PD, such as a mobile health application, fasting-mimicking diet, relaxation training, and guided imaging.

CONCLUSION

These findings highlight the importance of considering PD and coping strategies in patients with LABC from diagnosis to the end of NAT. The results suggest that effective psychological interventions should be implemented.

Patients with Chronic Pain: Are Mindfulness Traits Protective Against Distress, Anxiety and Depression?

OBJECTIVE

To investigate mindfulness traits/attitudes as protective factors against chronic pain related distress, depression and anxiety.

METHOD

Fifty patients (25 with chronic non-oncologic pain-NOP; 25 with chronic oncologic pain-COP) were administered with the following scales: Visual Analogue Scale (VAS), Pain Disability Index (PDI), Italian Questionnaire for Pain (QUID), Perceived Stress Scale (PSS), State and Trait Anxiety Scale (STAY-y1 module), Beck Depression Inventory II (BDI-II), Pittsburgh Sleep Quality Index (PSQI), Psychological General Well Being Index (PGWBI), Mindful Attention Awareness Scale (MAAS).

RESULTS

MAAS value ≥ 4.38 was adopted as cut-off to compare 'high level of mindfulness' (HM) vs. 'normal level of mindfulness' (NM) attitudes. Twenty-six patients (52%) scored ≥4.38, with no different distribution between NOP and COP. HM patients scored significantly lower than NM patients on PDI 'family/home responsibilities' domain (4.5±3.2 vs. 6.4±2.8; p<.037), and on PSS (17.8±2.6 vs. 20.9±2.5; p<.0001), STAY-y1 (9.4±1.8 vs. 10.3±2.1; p<.0001), BDI-II (7.8±5.0 vs. 17.6±8.6; p<.0001) total scores. HM scored significantly higher than NM patients in all PGWBI domains. A multiple regression analysis was carried out to analyze the predictor variables of PGWB. The most complete model considered the variables MAAS, STAIy and VAS (F=42.21; p<.0001), that accounted for the 71.6% of PGWB variance. MAAS score was the only variable positively predicting for PGWB; STAIy and VAS scores predicted negatively.

CONCLUSIONS

Chronic pain patients with high levels of mindfulness attitudes experienced less distress, anxiety, depressive symptoms, and more physical and general wellbeing than patients with low levels of mindfulness attitudes.

Psychological Aspects of Breast Cancer

Breast cancer is the most commonly diagnosed cancer in women. Associated psychological symptoms include stress, adjustment difficulties, anxiety, depression, impaired cognitive function, sleep disturbances, altered body image, sexual dysfunction, and diminished overall well-being. Distress screening and assessment identifies women who will benefit from therapeutic interventions. Addressing these symptoms improves compliance with treatment and outcomes including disease-related outcomes, psychological symptoms, and quality of life. The most effective treatments include teaching coping skills such as expressing emotion, along with other structured cognitive behavioral, interpersonal, and mindfulness approaches. Patients should be provided these psychosocial supports throughout their cancer journey.

Immediate impact of Mindfulness-Based Cognitive Therapy (MBCT) among women with breast cancer: a systematic review and meta-analysis

BACKGROUND

Mindfulness-based cognitive therapy (MBCT) may have positive physiological and psychological benefits for breast cancer survivors. However, few studies involved a combination of the relevant literatures to confirm the effects.

METHODS

Our study included randomized controlled trials (RCTs) and non-RCTs comparing interventions of MBCT and control protocols for alleviation of symptoms among breast cancer survivors. We calculated pooled mean differences (MDs), standardized mean differences (SMDs), and 95% confidence intervals (CIs) by using random effects models to estimate summary effect sizes.

RESULTS

Thirteen trials with 20-245 participants were considered in our studies; for the meta-analysis, 11 of these studies were eligible for assessment. The pooled meta-analysis results revealed that at the end of the MBCT intervention, participants' anxiety (SMD, - 0.70; 95% CI, - 1.26 to - 0.13; I2 = 69%), pain (SMD, - 0.64; 95% CI, - 0.92 to - 0.37; I2 = 0%), and depression (SMD, - 0.65; 95% CI, - 1.14 to - 0.17; I2 = 75%) levels significantly decreased, and their mindfulness (MD, 8.83; 95% CI, 3.88 to 13.78; I2 = 68%) levels significantly increased.

CONCLUSION

The MBCT may be associated with improved pain, anxiety, depression, and mindfulness. However, the quantitative analysis pointed to an inconclusive result due to moderate to high levels of heterogeneity among indicator of anxiety, depression, and mindfulness. Future work requires more studies to better elucidate the clinical significance of this possible association. The results suggest that MBCT is highly beneficial as an intervention for patients who have received treatment for breast cancer.

Optimising psychological treatment for pain after breast cancer: a factorial design study protocol in Denmark

INTRODUCTION

One in five breast cancer (BC) survivors are affected by persistent pain years after completing primary treatment. While the efficacy of psychological interventions for BC-related pain has been documented in several meta-analyses, reported effect sizes are generally modest, pointing to a need for optimisation. Guided by the Multiphase Optimization Strategy, the present study aims to optimise psychological treatment for BC-related pain by identifying active treatment components in a full factorial design.

METHODS AND ANALYSIS

The study uses a 2×3 factorial design, randomising 192 women with BC-related pain (18-75 years) to eight experimental conditions. The eight conditions consist of three contemporary cognitive-behavioural therapy components, namely: (1) mindful attention, (2) decentring, and (3) values and committed action. Each component is delivered in two sessions, and each participant will receive either zero, two, four or six sessions. Participants receiving two or three treatment components will be randomised to receive them in varying order. Assessments will be conducted at baseline (T1), session by session, every day for 6 days following the first session in each treatment component, at post-intervention (T2) and at 12-week follow-up (T3). Primary outcomes are pain intensity (Numerical Rating Scale) and pain interference (Brief Pain Inventory interference subscale) from T1 to T2. Secondary outcomes are pain burden, pain quality, pain frequency, pain catastrophising, psychological distress, well-being and fear of cancer recurrence. Possible mediators include mindful attention, decentring, and pain acceptance and activity engagement. Possible moderators are treatment expectancy, treatment adherence, satisfaction with treatment and therapeutic alliance.

ETHICS AND DISSEMINATION

Ethical approval for the present study was received from the Central Denmark Region Committee on Health Research Ethics (no: 1-10-72-309-40). Findings will be made available to the study funders, care providers, patient organisations and other researchers at international conferences, and published in international, peer-reviewed journals.

Psychosocial Interventions for Pain Management in Breast Cancer Survivors: A RE-AIM Evaluation

Psychosocial interventions for breast-cancer-related pain are effective, yet over 45% of survivors continue to struggle with this often-chronic side effect. This study evaluated multilevel indicators that can influence successful translation of interventions into clinical practice. The Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework was applied to evaluate reporting of individual and setting/staff-level intervention indicators. A systematic search and multi-step screening process identified 31 randomized controlled trials for psychosocial interventions for breast cancer-related pain. Average reporting of indicators for individual-level dimensions (Reach and Effectiveness) were 65.2% and 62.3%, respectively. Comparatively, indicators for setting/staff-level dimensions were reported at a lower average frequency (Implementation, 46.8%; Adoption, 15.2%; Maintenance, 7.7%). Low reporting of setting/staff-level dimensions suggests gaps in the sustained implementation of psychosocial interventions. Implementation science methods and frameworks could improve trial design and accelerate the translation of psychosocial interventions for breast cancer-related pain into clinical practice.

Efficacy of group therapy to reduce mental distress in women with non-metastatic breast cancer: A systematic review and meta-analysis of randomized controlled trials

OBJECTIVE

Group treatments have proven to be effective for many mental disorders and showed beneficial effects in patients with medical illness. Aim of this systematic review and meta-analysis is to summarize the efficacy of group therapy for women with non-metastatic breast cancer.

METHODS

We included studies comparing group therapy for women with non-metastatic breast cancer to non-active control groups, active control conditions, and individual psychotherapy. The primary outcome was mental distress, secondary outcomes were quality of life, coping, existential outcomes, fatigue, pain, and side effects. A comprehensive search was conducted in Medline, Web of Science, CENTRAL, PsycINFO, and DARE complemented by a manual search. Random-effects meta-analyses were run separately for different types of control groups.

RESULTS

Thirty-seven studies (5902 patients) were included. Small effects on mental distress in favor of group treatment were found (non-active control groups: n = 19, g = 0.42, 95% CI [0.29; 0.56], I²  = 61.6%; active control conditions: n = 6, g = 0.20, 95% CI [0.06; 0.35], I²  = 0%). Cognitive-behavioral therapy (CBT) and third wave CBT group approaches proved to be most effective. Group treatments also showed beneficial effects on secondary outcomes, with most profound evidence on quality of life and coping.

CONCLUSIONS

Results suggest that group interventions have the potential to reduce mental distress in women facing breast cancer. In the light of the considerable heterogeneity of most study effects, there is a need for more rigorous studies to strengthen the promising evidence and for trials examining the impact of patient and intervention characteristics on outcomes.

Psychological interventions for women with non-metastatic breast cancer

BACKGROUND

Breast cancer is the most common cancer affecting women worldwide. It is a distressing diagnosis and, as a result, considerable research has examined the psychological sequelae of being diagnosed and treated for breast cancer. Breast cancer is associated with increased rates of depression and anxiety and reduced quality of life. As a consequence, multiple studies have explored the impact of psychological interventions on the psychological distress experienced after a diagnosis of breast cancer. This review is an update of a Cochrane Review first published in 2015.

OBJECTIVES

To assess the effect of psychological interventions on psychological morbidities and quality of life among women with non-metastatic breast cancer.  SEARCH METHODS: We searched the Cochrane Breast Cancer Group Specialised Register, CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO, the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) and ClinicalTrials.gov up to 16 March 2021. We also scanned the reference lists of relevant articles.

SELECTION CRITERIA

Randomised controlled trials that assessed the effectiveness of psychological interventions for women with non-metastatic breast cancer.

DATA COLLECTION AND ANALYSIS

Two review authors independently appraised, extracted data from eligible trials, and assessed risk of bias and certainty of the evidence using the GRADE approach. Any disagreement was resolved by discussion. Extracted data included information about participants, methods, the intervention and outcomes.

MAIN RESULTS

We included 60 randomised controlled trials comprising 7998 participants. The most frequent reasons for exclusion were non-randomised trials and the inclusion of women with metastatic disease. The updated review included 7998 randomised women; the original review included 3940 women. A wide range of interventions was evaluated. Most interventions were cognitive- or mindfulness-based, supportive-expressive, and educational. The interventions were mainly delivered face-to-face (56 studies) and in groups (50 studies) rather than individually (10 studies). Most intervention sessions were delivered on a weekly basis with an average duration of 14 hours. Follow-up time ranged from two weeks to 24 months.  Pooled standardised mean differences (SMD) from baseline indicated that the intervention may reduce depression (SMD -0.27, 95% confidence interval (CI) -0.52 to -0.02; P = 0.04; 27 studies, 3321 participants, I2 = 91%, low-certainty evidence); anxiety (SMD -0.43, 95% CI -0.68 to -0.17; P = 0.0009; 22 studies, 2702 participants, I2 = 89%, low-certainty evidence); mood disturbance in the intervention group (SMD -0.18, 95% CI -0.31 to -0.04; P = 0.009; 13 studies, 2276 participants, I2 = 56%, low-certainty evidence); and stress (SMD -0.34, 95% (CI) -0.55 to -0.12; P = 0.002; 8 studies, 564 participants, I2 = 31%, low-certainty evidence). The intervention is likely to improve quality of life in the intervention group (SMD 0.78, 95% (CI) 0.32 to 1.24; P = 0.0008; 20 studies, 1747 participants, I2 = 95%, low-certainty evidence). Adverse events were not reported in any of the included studies.

AUTHORS' CONCLUSIONS

Based on the available evidence, psychological intervention may have produced favourable effects on psychological outcomes, in particular depression, anxiety, mood disturbance and stress. There was also an improvement in quality of life in the psychological intervention group compared to control group. Overall, there was substantial variation across the studies in the range of psychological interventions used, control conditions, measures of the same outcome and timing of follow-up.

Evidence Mapping Based on Systematic Reviews of Cognitive Behavioral Therapy for Neuropathic Pain

Objective

This evidence mapping is aimed at identifying, summarizing, and analyzing the available evidence on cognitive behavioral therapy (CBT) for neuropathic pain (NP).

Methods

This study was conducted following the methodology of Global Evidence Mapping (GEM). Searches were conducted in PubMed, Embase, the Cochrane Library, and PsycINFO to identify systematic reviews (SRs) with or without meta-analysis published before February 15, 2022. The authors independently assessed eligibility, extracted data, and evaluated the methodological quality of the included SRs using AMSTAR-2. The results were presented in the tables and a bubble plot based on the identified population-intervention-comparison-outcome (PICO) questions.

Results

A total of 34 SRs met the eligibility criteria. According to the AMSTAR-2, 2 SRs were rated "high," 2 SRs were rated "moderate," 6 SRs were rated "low," and 24 SRs were rated "critically low." The most common study design utilized to evaluate the efficacy of CBT for NP was the randomized controlled trial. In total, 24 PICOs were identified. Migraine was the most studied population. CBT for NP usually reaches the "potentially better" result at follow-up.

Conclusions

Evidence mapping is a useful way to present existing evidence. Currently, the existing evidence on CBT for NP is limited. Overall, the methodological quality of the included SRs was low. Further improvements in the methodological quality of SRs and more research on the most efficient CBT formats for NP are recommended in the future.

Integrative Medicine for Pain Management in Oncology: Society for Integrative Oncology-ASCO Guideline

PURPOSE

The aim of this joint guideline is to provide evidence-based recommendations to practicing physicians and other health care providers on integrative approaches to managing pain in patients with cancer.

METHODS

The Society for Integrative Oncology and ASCO convened an expert panel of integrative oncology, medical oncology, radiation oncology, surgical oncology, palliative oncology, social sciences, mind-body medicine, nursing, and patient advocacy representatives. The literature search included systematic reviews, meta-analyses, and randomized controlled trials published from 1990 through 2021. Outcomes of interest included pain intensity, symptom relief, and adverse events. Expert panel members used this evidence and informal consensus to develop evidence-based guideline recommendations.

RESULTS

The literature search identified 227 relevant studies to inform the evidence base for this guideline.

RECOMMENDATIONS

Among adult patients, acupuncture should be recommended for aromatase inhibitor-related joint pain. Acupuncture or reflexology or acupressure may be recommended for general cancer pain or musculoskeletal pain. Hypnosis may be recommended to patients who experience procedural pain. Massage may be recommended to patients experiencing pain during palliative or hospice care. These recommendations are based on an intermediate level of evidence, benefit outweighing risk, and with moderate strength of recommendation. The quality of evidence for other mind-body interventions or natural products for pain is either low or inconclusive. There is insufficient or inconclusive evidence to make recommendations for pediatric patients. More research is needed to better characterize the role of integrative medicine interventions in the care of patients with cancer.Additional information is available at https://integrativeonc.org/practice-guidelines/guidelines and www.asco.org/survivorship-guidelines.

Can Mindfulness-Based Stress Reduction Influence the Quality of Life, Anxiety, and Depression of Women Diagnosed with Breast Cancer? -A Review

INTRODUCTION

Breast cancer is the most common form of cancerous disease worldwide. Its treatment leads to a variety of physiological and psychological side effects. This review investigates the question of how mindfulness-based stress reduction (MBSR), a stress management program, can influence the quality of life, anxiety, and depression of women diagnosed with breast cancer.

METHODS

A systematic literature search was conducted in PubMed/MEDLINE and Cochrane Library. Screening by title, abstract and full text was performed, whereby only those articles were included that fit the inclusion criteria. A risk of bias assessment was performed for each included study.

RESULTS

Overall, six studies were included, but not every study investigated all three outcomes. Two studies found positive impacts on quality of life, whereas three did not find a positive correlation between the intervention and quality of life. Four out of six studies found a positive relation between MBSR and anxiety scores, but only half of the included studies found positive results for the interaction between MBSR and depression scores.

CONCLUSION

Published data suggest that anxiety can be positively influenced by MBSR, which can be used to improve the psychological care of breast cancer patients, both during and after treatment. However, further studies with larger patient numbers and longer observation periods should be conducted in order to elucidate the full potential of MSBR on important areas such as depression and quality of life.

A systematic review of economic analyses of psychological interventions and therapies in health-related settings

Background

This review aims to synthesise evidence on the economic impact of psychological interventions and therapies when applied to a broad range of physical health conditions.

Methods

The following bibliographic databases were searched for relevant articles: MEDLINE (Ovid), EMBASE (Ovid) and PsycINFO (Ebsco). As this review was intended to update an earlier review, the date range for the search was restricted to between January 2012 and September 2018. Reference lists from the review articles were also searched for relevant articles. Study quality was evaluated using the Scottish Intercollegiate Network Guidelines (SIGN) appraisal checklists for both economic studies and Randomised Controlled Trials (RCTs). When the economic analyses did not provide sufficient detail for quality evaluation, the original RCT papers were sought and these were also evaluated. Half of the papers were quality rated by a second author. Initial agreement was high and all disagreements were resolved by discussion.

Results

This yielded 1408 unique articles, reduced to 134 following screening of the title and abstract. The full texts of the remaining articles were reviewed by at least one team member and all exclusions were discussed and agreed by the team. This left 46 original research articles, alongside five systematic reviews. Fifty-seven per cent of the articles were deemed to be of high quality, with the remainder of acceptable quality. Fifteen different medical conditions were covered, with chronic pain (10 articles) and cancer (9 articles) being the two most investigated health conditions. Three quarters of the papers reviewed showed evidence for the cost-effectiveness of psychological interventions in physical health, with the clearest evidence being in the field of chronic pain and cancer.

Conclusions

This paper provides a comprehensive integration of the research on the cost-effectiveness of psychological therapies in physical health. Whilst the evidence for cost-effectiveness in chronic pain and cancer is encouraging, some health conditions require further study. Clearly, as the primary research is international, and was therefore conducted across varying health care systems, caution must be exercised when applying the results to counties outside of those covered. Despite this, the results are of potential relevance to service providers and funders.

For whom and what outcomes does cognitive-behavioral-therapy work among cancer survivors: a systematic review and meta-analysis

OBJECTIVE

To perform a systematic review and meta-analysis of CBT for individuals diagnosed with cancer across a broad range of outcome domains, i.e., functional health, psychological health, health behaviors, social relational, and general wellness.

METHODS

A comprehensive search of 7 databases, 91 published reviews, and 4 professional websites was performed on August 30th, 2021. English-language clinical trials of CBT for cancer patients/survivors were included. Studies were independently screened, and data were extracted by 2 reviewers, and discrepancies were resolved by consensus among the investigative team. A total of 151 clinical trials (154 articles) published between 1986 and 2021 were included in the analysis.

RESULTS

CBT was overall effective for cancer patients/survivors in the domains of functional health, g = 0.931, p < 0.001, psychological health, g = 0.379, p < 0.001, and general wellness, g = 0.257, p < 0.001, but ineffective in domains of health behaviors, g = 0.792, p > 0.05, and social relational outcomes, g = 0.319, p > 0.05. Additional subgroup and moderator analyses further revealed CBT's differential treatment effect for different within domain outcomes, across different cancer disease stages, and CBT delivery format.

CONCLUSIONS

Findings of the study showed that CBT is an effective treatment for individuals diagnosed with cancer. However, treatment effects differ by important disease- and intervention-related factors, which should be considered when recommending CBT for cancer patients/survivors.

Pre- and post-operative psychological interventions to prevent pain and fatigue after breast cancer surgery (PREVENT): Protocol for a randomized controlled trial

Background

Breast cancer is the most common cancer type among women worldwide with over a million new cases each year. More than 40% of these women will struggle with chronic pain and fatigue after surgery, regardless of surgical procedure. These consequences are detrimental and result in distress and disability, including work disability. Few attempts have been made to prevent chronic pain and fatigue after surgery by applying a psychological approach, despite psychological risk factors being crucial in the development of both chronic pain and fatigue. In this study, we aim to develop and test an easily implementable strategy of preventing chronic pain and fatigue after breast cancer surgery. The intervention strategy involves a pre-operative hypnosis session and a web-based post-operative Acceptance and Commitment Therapy (ACT). The hypnosis has previously been found effective in alleviating acute post-operative pain and fatigue in breast cancer patients, while ACT is well suited to cancer populations as it offers a model of healthy adaptation to difficult circumstances. Together they form an intervention strategy with both a preventive and a rehabilitative focus.

Methods/Design

This randomized controlled trial aims to estimate the effects of the pre- and post- operative interventions compared to attentional control and treatment as usual (TAU) and will also include a qualitative process evaluation. Participants will be randomized to receive either a pre-operative brief hypnosis session and a post-operative web-based psychological intervention (iACT) or a pre-operative one-session mindfulness through an audio file and post-operative TAU. Self-reported questionnaire data and biomarker data will be assessed pre-surgery, post-surgery and 3 and 12 months after surgery. In addition, we will assess registry data on sick leave and prescriptions until 2-year follow-up. In the qualitative process evaluation, data will be collected from participants from both study arms (through interviews and a diary) and two different analyses performed (socio-narrative and Grounded Theory) with the objective to describe the development of chronic post-surgical pain and fatigue and the potential influence of the interventions on these processes. The study is set-up to demonstrate a minimum difference in pain of 1 point on NRS (0–10) and 3 points on FACIT-F (0–52) between the groups at 3-months follow-up by including 200 breast cancer patients in total.

Discussion

This trial will be the first study to estimate the effect of a combined pre-operative hypnosis with a post-operative iACT to prevent pain and fatigue after breast cancer surgery. The results from our study might i) help the large group of women affected by chronic pain and fatigue after breast cancer surgery, ii) shed light on the mechanisms involved in chronic pain and fatigue development, and iii) serve as a model for other surgical procedures.

Psychological and Non-Pharmacologic Treatments for Pain in Cancer Patients: A Systematic Review and Meta-Analysis

CONTEXT

Pain is the most fearful symptom in cancer. Although there is a relationship between psychosocial variables and oncologic pain, psychological and non-pharmacological treatments for pain management in cancer patients are not very widespread.

OBJECTIVES

To analyze the efficacy of psychological and non-pharmacological treatments for reducing pain in cancer patients.

METHODS

We performed a systematic review following the PRISMA protocol. In January 2021, data were extracted from PubMed, Web of Science and Scopus, including randomised controlled trials (RCT) published in the last five years (from 28 January, 2015 to December 15, 2020), in the English language and whose sample was patients with cancer pain. The database search used the following keywords: cancer, cancer-related pain, psychological intervention, non-pharmacologic intervention. The Cochrane risk of bias assess ment for randomised trials (RoB 2) was used for quality appraisal.

RESULTS

After the inclusion and exclusion criteria were applied, ten papers were fully screened. The evidence suggested that the most effective interventions to reduce cancer pain were mindfulness-based cognitive therapy, guided imagery and progressive muscle relaxation and emotional and symptom focused engagement (EASE). Music therapy and brief cognitive behavioral strategies (CBS) require more research, while coping skills training and yoga did not show positive effects. Overall, we obtained a moderate size effect (d = 0.642, 95% CI: 0.125-1.158) favourable to psychological and non-pharmacologic treatments at post-treatment, which increased at follow-up (k = 5, d = 0.826, 95% CI: 0.141-1.511).

CONCLUSION

This study provides insight into psychological interventions which might be applied and contribute to cancer-related pain reduction in adults. Although the results are not completely consistent, they may shed light on psychology applications in the oncology environment.

Analgesic Effects of Repetitive Transcranial Magnetic Stimulation in Patients With Advanced Non-Small-Cell Lung Cancer: A Randomized, Sham-Controlled, Pilot Study

Objective

Current pharmacological intervention for the cancer-related pain is still limited. The aim of this study was to explore whether repetitive transcranial magnetic stimulation (rTMS) could be an effective adjuvant therapy to reduce pain in patients with advanced non-small cell lung cancer (NSCLC).

Methods

This was a randomized, sham–controlled study. A total of 41 advanced NSCLC patients with uncontrolled pain (score≥4 on pain intensity assessed with an 11-point numeric rating scale) were randomized to receive active (10 Hz, 2000 stimuli) (n = 20) or sham rTMS (n = 20) for 3 weeks. Pain was the primary outcome and was assessed with the Numeric Rating Scale (NRS). Secondary outcomes were oral morphine equivalent (OME) daily dose, quality of life (WHO Quality of Life-BREF), and psychological distress (the Hospital Depression and Anxiety Scale). All outcomes were measured at baseline, 3 days, 1 week, 2 weeks, and 3 weeks.

Results

The pain intensity in both groups decreased gradually from day 3 and decreased to the lowest at the week 3, with a decrease rate of 41.09% in the rTMS group and 23.23% in the sham group. The NRS score of the rTMS group was significantly lower than that of the sham group on the week 2 (p < 0.001, Cohen’s d =1.135) and week 3 (p=0.017, Cohen’s d = -0.822). The OME daily dose, physiology and psychology domains of WHOQOL-BREF scores, as well as the HAM-A and HAM-D scores all were significantly improved at week 3 in rTMS group.

Conclusion

Advanced NSCL patients with cancer pain treated with rTMS showed better greater pain relief, lower dosage of opioid, and better mood states and quality of life. rTMS is expected to be a new effective adjuvant therapy for cancer pain in advanced NSCLC patients.

The mediator role of stigma in the association of mindfulness and social engagement among breast cancer survivors in China

PURPOSE

This study aims to explore the association between mindfulness and social engagement among Chinese breast cancer survivors (BCSs) and the mediator role of stigma in the relation of mindfulness and social engagement.

METHODS

This cross-sectional study was conducted among 937 BCSs from March to April 2021 in Shanghai, China. Data were collected using the Mindful Attention Awareness Scale, the Stigma Scale for Chronic Illness 8-item version, and the index of social engagement. Descriptive statistics, independent-sample t-test, one-way ANOVA, and regression analyses were used to explore the role of stigma in the association of mindfulness and social engagement among Chinese BCSs.

RESULTS

Social engagement levels differed significantly by participant's BMI, education level, employment status, personal monthly income, monthly per capita household income. Mindfulness was positively correlated with social engagement, and stigma was negatively correlated with mindfulness and social engagement among Chinese BCSs. Stigma plays a complete mediating role in the relationship between mindfulness and social engagement in BCSs.

CONCLUSION

In the practice of individual mindfulness intervention on social engagement of BCSs, health care providers should identify and eliminate the constraints, which restrain the reduction of stigma level while individual mindfulness is being enhanced.

Are mindfulness treatments effective for pain in cancer patients? A systematic review and meta-analysis

BACKGROUND AND OBJECTIVE

Mindfulness-based interventions (MBIs) have been recently applied in pain management and cancer care. However, inconsistencies exist concerning the effectiveness of MBIs on pain control among cancer patients. Therefore, this study aimed to examine the efficacy of MBIs on pain in cancer patients via a systematic review and meta-analysis of randomized controlled trials (RCTs).

METHODS

Databases (MEDLINE, PubMed, Embase, CINAHL, PsycINFO, Cochrane Central Register of Controlled Trials and ClinicalTrials.gov) were searched using key terms related to pain, cancer and mindfulness. The primary outcome was pain intensity. Standardized mean difference (SMD) of each outcome with 95% confidence interval (95% CI) was calculated. The quality of evidence was assessed by GRADE assessment.

RESULTS

Ten RCTs with 843 participants were included. Significant pooled effects of MBIs on pain intensity were found at both short-term (SMD = -0.19, 95% CI [-0.33 to -0.04]) and long-term (SMD = -0.20, 95% CI [-0.35 to -0.05]) follow-up, whereas no significance was observed for pain interference. In subgroup analyses, significant intervention effects were only seen in clinic-based MBIs compared to remote MBIs, and pooled effects of MBIs in attenuating pain were discovered relative to passive rather than active comparators. GRADE ratings showed moderate certainty of evidence in MBIs for pain intensity but low for pain interference.

CONCLUSIONS

The efficacy of MBIs in reducing pain intensity among cancer patients was revealed in this meta-analysis, albeit with a small effect size. Future research is warranted to optimize mindfulness treatment for pain control in cancer patients with high methodological quality and a large sample size.

SIGNIFICANCE

The effect of MBIs on pain in cancer patients was demonstrated in our analysis, albeit with small effect sizes. High-quality RCTs are needed to verify the efficacy of MBIs on cancer patients or survivors with pain complaints. Future trials should take into account the specific pain outcome measures (pain intensity or pain interference), the approach of intervention provision (clinic-based or remote MBI, group or individual practice), the duration and frequency of interventions and the comparators (passive or active control arms).

Post-Mastectomy Pain Syndrome: An Up-to-Date Review of Treatment Outcomes

BACKGROUND

Post-mastectomy pain syndrome (PMPS) is a known debilitating surgical complication. While research on prevention, risk factors, and treatments have been conducted, there remains no cohesive treatment paradigm. The aim of our study is to synthesize the existing evidence on PMPS treatment, which may facilitate the implementation of standardized, effective management strategies.

METHODS

Using Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, a comprehensive search was developed and translated for MEDLINE, Cochrane Library, EMBASE, CINAHL, PsycINFO, Web of Science, and ClinicalTrials.gov. The databases were searched using a combination of free terms, phrase searching, and database-specific controlled vocabulary related to PMPS. All unique records were by two independent reviewers. Publications on chronic (>3 months duration) pain after breast cancer-related surgery were included. Limited case series, case reports, and editorials were not included.

RESULTS

A total of 3402 articles from the years 1946-2019 resulted from the literature search after deduplication. Twenty-seven articles met final inclusion criteria for analysis, which revealed 10 major treatment modalities: fat grafting, neuroma surgery, lymphedema surgery, nerve blocks and neurolysis, laser, antidepressants, neuromodulators, physical therapy, mindfulness-based cognitive therapy, and capsaicin.

CONCLUSIONS

In this review, we present a comprehensive assessment of the treatments available for PMPS that may help guide breast surgeons and reconstructive surgeons to employ the most effective treatment strategies for these patients. This review supports the importance of multimodal, multidisciplinary care in improving the management of PMPS.

A Targeted Approach to Post-Mastectomy Pain and Persistent Pain following Breast Cancer Treatment

Persistent pain following treatment for breast cancer is common and often imprecisely labeled as post-mastectomy pain syndrome (PMPS). PMPS is a disorder with multiple potential underlying causes including intercostobrachial nerve injury, intercostal neuromas, phantom breast pain, and pectoralis minor syndrome. Adding further complexity to the issue are various musculoskeletal pain syndromes including cervical radiculopathy, shoulder impingement syndrome, frozen shoulder, and myofascial pain that may occur concurrently and at times overlap with PMPS. These overlapping pain syndromes may be difficult to separate from one another, but precise diagnosis is essential, as treatment for each pain generator may be distinct. The purpose of this review is to clearly outline different pain sources based on anatomic location that commonly occur following treatment for breast cancer, and to provide tailored and evidence-based recommendations for the evaluation and treatment of each disorder.

Are mind-body therapies effective for relieving cancer-related pain in adults? A systematic review and meta-analysis

OBJECTIVE

To assess whether mind-body therapies are effective for relieving cancer-related pain in adults, since at least one-third of adults with cancer are affected by moderate or severe pain.

METHODS

We searched for all randomized or quasi-randomized controlled trials that included adults (≥18 years) with cancer-related pain who were treated with mind-body therapies (mindfulness, hypnosis, yoga, guided imagery, and progressive muscle relaxation) in MEDLINE, Embase, CINAHL, Cochrane Central Register of Controlled Trials (CENTRAL), Science Citation Index, Web of Science, trials registers, and reference lists. The primary outcome was pain intensity. We calculated the standardized mean differences and 95% confidence intervals (CIs) and assessed the risk of bias.

RESULTS

We identified 40 primary studies involving a total of 3569 participants. The meta-analysis included 24 studies (2404 participants) and showed a significant effect of -0.39 (95% CI -0.62 to -0.16) with considerable heterogeneity (I²  = 86.3%, p < 0.001). After we excluded four "outlier" studies in sensitivity analyses, the effect size remained significant but weaker. There was a high risk of bias in all studies, for example, performance bias due to lack of participant blinding. Patients in multiple settings were included but many studies were of low quality.

CONCLUSIONS

Mind-body therapies may be effective in improving cancer pain, but the quality of the evidence is low. There is a need for further high-quality clinical trials.

Recent trends in the management of depression in persons with cancer

PURPOSE OF REVIEW

Depression is a prevalent comorbidity in cancer that significantly increases the risk for numerous negative health outcomes. This review updates the current evidence base for management of depression in cancer, highlighting new research directions based on the inflammatory hypothesis of depression.

RECENT FINDINGS

Research on pharmacotherapy and psychotherapy for depression in cancer has shown mixed efficacy partly because of methodological issues arising from the phenomenology of depression in cancer. After decades of stagnancy, more recent high-quality clinical trials are beginning to provide an evidence base to guide treatment. Inflammatory cytokine-associated depression is a subtype of depression that may have particular relevance in cancer, opening new avenues to explore therapeutic targets and biobehavioral impacts of interventions, which may improve cancer outcomes.

SUMMARY

The continuum of severity in cancer-related depression is important to consider in management approaches. Choice of treatment should be personalized to the patient and their symptom profile as there is currently insufficient evidence to recommend any particular medication or psychotherapy over another. Psychological interventions should be considered first line for mild-to-moderate depression, and pharmacological treatment added for more severe depression, which can be optimally delivered within a collaborative care model.

Effects of Mindfulness-Based Cognitive Therapy for Chronic Pain: A Multicenter Study

The prevalence of chronic pain in Spain is 15%. The objective of this study was to evaluate the efficacy of mindfulness-based cognitive therapy on patients with chronic pain. A quasi-experimental design of repeated measures pre- and post-test (N = 57) was carried out at three hospitals from the province of Alicante. Self-reported assessment measurements of pain intensity, anxiety-depression symptoms, perception of health status, interference of pain on sleep, self-efficacy in pain, acceptance, and mindfulness attitude were included. The T-test indicates significant differences in intensity of present pain, mental quality of life, and depression (medium effect sizes), as well as in self-efficacy: total score, symptom management and pain control (medium effect sizes), sleep disturbances and quantity of sleep (large effect sizes). MBCT is effective in reducing many symptoms in patients with chronic pain, although its maintenance needs to be further investigated.

Pain Management Experiences Among Hospitalized Postcraniotomy Brain Tumor Patients

BACKGROUND

Brain tumors account for the majority of central nervous system tumors, and most are removed by craniotomies. Many postcraniotomy patients experience moderate or severe pain after surgery, but patient perspectives on their experiences with pain management in the hospital have not been well described.

OBJECTIVE

The aim of this study was to describe how patients who have undergone a craniotomy for brain tumor removal experience pain management while hospitalized.

METHODS

Qualitative descriptive methods using semistructured interviews were conducted with patients on a neurological step-down unit in an urban teaching hospital in the Midwest United States. Interviews focused on how patients experienced postcraniotomy pain and how it was managed. Narratives were analyzed with standard content analytic procedures.

RESULTS

Twenty-seven participants (median age, 58.5 years; interquartile range, 26-41 years; range, 21-83 years) were interviewed. The majority were white (n = 25) and female (n = 15) and had an anterior craniotomy (n = 25) with sedation (n = 17). Their pain experiences varied on 2 dimensions: salience of pain during recovery and complexity of pain management. Based on these dimensions, 3 distinct types of pain management experiences were identified: (1) pain-as-nonsalient, routine pain management experience; (2) pain-as-salient, routine pain management experience; and (3) pain-as-salient, complex pain management experience.

CONCLUSIONS

Many postcraniotomy patients experience their pain as tolerable and/or pain management as satisfying and effective; others experience pain and pain management as challenging.

IMPLICATIONS FOR PRACTICE

Clinicians should be attuned to needs of patients with complex pain management experiences and should incorporate good patient/clinician communication.

Marked sexual dimorphism in neuroendocrine mechanisms for the exacerbation of paclitaxel-induced painful peripheral neuropathy by stress

Chemotherapy-induced neuropathic pain is a serious adverse effect of chemotherapeutic agents. Clinical evidence suggests that stress is a risk factor for development and/or worsening of chemotherapy-induced peripheral neuropathy (CIPN). We evaluated the impact of stress and stress axis mediators on paclitaxel CIPN in male and female rats. Paclitaxel produced mechanical hyperalgesia, over the 4-day course of administration, peaking by day 7, and still present by day 28, with no significant difference between male and female rats. Paclitaxel hyperalgesia was enhanced in male and female rats previously exposed to unpredictable sound stress, but not in rats that were exposed to sound stress after developing paclitaxel CIPN. We evaluated the role of the neuroendocrine stress axes: in adrenalectomized rats, paclitaxel did not produce hyperalgesia. Intrathecal administration of antisense oligodeoxynucleotides (ODN) reduced expression of β2-adrenergic receptors on nociceptors, and paclitaxel-induced hyperalgesia was slightly attenuated in males, but markedly attenuated in females. By contrast, after intrathecal administration of antisense ODN to decrease expression of glucocorticoid receptors, hyperalgesia was markedly attenuated in males, but unaffected in females. Both ODNs together markedly attenuated paclitaxel-induced hyperalgesia in both males and females. We evaluated paclitaxel-induced CIPN in stress-resilient (produced by neonatal handling) and stress-sensitive (produced by neonatal limited bedding). Neonatal handling significantly attenuated paclitaxel-induced CIPN in adult male, but not in adult female rats. Neonatal limited bedding did not affect the magnitude of paclitaxel-induced CIPN in either male or female. This study provides evidence that neuroendocrine stress axis activity has a marked, sexually dimorphic, effect on paclitaxel-induced painful CIPN.

A systematic review and meta-analysis of psychological interventions to improve mental wellbeing

Our current understanding of the efficacy of psychological interventions in improving mental states of wellbeing is incomplete. This study aimed to overcome limitations of previous reviews by examining the efficacy of distinct types of psychological interventions, irrespective of their theoretical underpinning, and the impact of various moderators, in a unified systematic review and meta-analysis. Four-hundred-and-nineteen randomized controlled trials from clinical and non-clinical populations (n = 53,288) were identified for inclusion. Mindfulness-based and multi-component positive psychological interventions demonstrated the greatest efficacy in both clinical and non-clinical populations. Meta-analyses also found that singular positive psychological interventions, cognitive and behavioural therapy-based, acceptance and commitment therapy-based, and reminiscence interventions were impactful. Effect sizes were moderate at best, but differed according to target population and moderator, most notably intervention intensity. The evidence quality was generally low to moderate. While the evidence requires further advancement, the review provides insight into how psychological interventions can be designed to improve mental wellbeing.

Internet-delivered Mindfulness-Based Cognitive Therapy for anxiety and depression in cancer survivors: Predictors of treatment response

BACKGROUND

The present study investigates possible predictors of treatment response in an Internet-delivered Mindfulness-Based Cognitive Therapy (iMBCT) intervention with therapist support. This iMBCT program, a fully online delivered intervention with asynchronous therapist support, has previously been shown to be efficacious in reducing symptoms of anxiety and depression in women treated for breast cancer and men treated for prostate cancer.

METHODS

Eighty-two breast- and prostate cancer survivors experiencing psychological distress received 8 weeks of therapist-guided iMBCT. Primary outcomes were improvement in anxiety and depression scores from baseline to post-treatment and from baseline to six-months follow-up. Clinical predictors included levels of depression and anxiety at the time of screening and at baseline, as well as time since diagnosis. Demographic predictors included age and educational level. Therapy-related predictors included working alliance, self-compassion, and five facets of mindfulness. Mixed Linear Models were employed to test the prediction effects over time.

RESULTS

Higher levels of baseline depression were associated with increased treatment response in anxiety at post-treatment, and lower levels of self-compassion were associated with increased treatment response in depression at post-treatment. None of the proposed predictors significantly predicted treatment response at six-months follow-up.

CONCLUSION

The findings suggest that iMBCT can be provided for cancer survivors regardless of their age, educational level, and time since diagnosis (up to five years) and that therapeutic alliance is not crucial for treatment response. We did not identify characteristics predicting treatment response, although many factors were tested. Still, other characteristics may be predictors, and given the relatively small sample size and a large number of statistical tests, the results should be interpreted with caution.

Mindfulness-Based Interventions in Cancer Survivors: A Systematic Review of Participants' Adherence to Home Practice

BACKGROUND

Although mindfulness-based interventions (MBIs) have demonstrated efficacy for alleviating psychological distress in cancer survivors, little is known about the extent to which participants adhere to assigned home practice. The purpose of this systematic review was to summarize and appraise the literature on rates and correlates of adherence to mindfulness home practice among cancer survivors.

METHODS

Four databases (PubMed, Psychology and Behavioral Sciences, PsycInfo, and CINAHL) were searched for studies published before October 15, 2020. Articles were included if they evaluated the benefits of an MBI program for adults with cancer.

RESULTS

Twenty-one studies (N=1811 participants) meeting the inclusion criteria were identified (randomized controlled trials (n=13), non-randomized controlled designs (n=2), single-group studies (n=6)). The pooled adherence rate for participants' home practice was 60% of the assigned amount, which equated to 27 min per day during the intervention period. There was some evidence for a relationship between home practice of mindfulness techniques and improvements in mood, stress, anxiety, depression, and fear of cancer recurrence (correlation coefficients ranged from 0.33 to 0.67). Factors including marital status, mood disturbance at baseline, intervention modality, and personality traits were evaluated in relation to adherence to home practice, but the current literature was inadequate to evaluate whether a relationship exists.

CONCLUSION

Adherence to mindfulness home practice among cancer survivors is suboptimal, and most of the correlates of adherence studied to date are non-modifiable. More research is warranted to scrutinize the role of home practice in mindfulness-based interventions, including assessment of modifiable factors influencing adherence to improve benefits for this population.

Thai Buddhism-Based Mindfulness for Pain Management in Thai Outpatients with Cancer: A Pilot Study

OBJECTIVE

This study aimed to evaluate Thai Buddhism-based Mindfulness (TBbM) feasibility based on recruitment and retention rates and to obtain preliminary data regarding changes (effect sizes) in pain severity and other outcomes when comparing control to intervention participants following TBbM use.

METHODS

A randomized controlled trial was conducted in the Outpatient Department at Sawanpracharak Hospital, Thailand, from April 2018 to February 2019. Seventeen participants completed the pretest and posttest. Both groups (control group [n = 10] and intervention group [n = 7]) received usual care and watched a 25-min educational video about cancer pain. The intervention group participated in a 3-day mindfulness training program at a Buddhist temple and continued practicing at home for 8 weeks. Data were collected at baseline and at 1 and 2 months postintervention.

RESULTS

One-hundred and thirty-five participants met the eligibility criteria; 112 (82%) declined to participate and 6 of 23 (26%) were lost to follow-up/dropped out. Control and intervention participants had an average age of 44 (± 8.77) and 56 years (± 7.41), respectively. When compared to the control group, the TBbM participants reported no statistically significant improvements in pain or other outcomes. While not statistically significant, the effect size indicated that pain did improve in the TBbM group (Cohen's d = 0.41).

CONCLUSIONS

Given the suboptimal recruitment and retention rates, modification of the intervention is warranted. Further, our findings suggest that the intervention had a moderate effect on pain. To evaluate efficacy, future adequately powered studies are needed to test a more feasible TBbM intervention.

Systematic scoping review of interactions between analgesic drug therapy and mindfulness-based interventions for chronic pain in adults: current evidence and future directions

Most patients with chronic pain do not find adequate pain relief with a single treatment, and accumulating evidence points to the added benefits of rational combinations of different treatments. Given that psychological therapies, such as mindfulness-based interventions (MBIs), are often delivered in conjunction with concomitant analgesic drug therapies (CADTs), this systematic scoping review examines the evidence for any interactions between MBIs and CADTs. The protocol for this review has been published and registered. MEDLINE, Cochrane Central Register of Controlled Trials, EMBASE, and PsycINFO databases were searched until July 2019. We included randomized controlled trials that evaluated the efficacy of MBIs for the treatment of chronic pain. A total of 40 randomized controlled trials (2978 participants) were included. Thirty-nine of 40 (97.5%) included mindfulness-based clinical trials allowed the use of CADTs. However, only 6 of these 39 (15.4%) trials provided adequate details of what these CADTs were, and only 4 (10.3%) trials controlled for CADTs. Of great relevance to this review, none of the included trials analyzed the interactions between MBIs and the CADTs to determine whether they have an additive, synergistic, or antagonistic effect on chronic pain. Adverse events were inconsistently reported, and no judgment could be made about safety. Future trials assessing the interactions between MBIs and CADTs, with better harms reporting, are needed to better define the role of MBIs in the management of chronic pain.

Association of Mindfulness-Based Interventions With Anxiety Severity in Adults With Cancer: A Systematic Review and Meta-analysis

IMPORTANCE

Mindfulness-based interventions (MBIs), grounded in mindfulness, focus on purposely paying attention to experiences occurring at the present moment without judgment. MBIs are increasingly used by patients with cancer for the reduction of anxiety, but it remains unclear if MBIs reduce anxiety in patients with cancer.

OBJECTIVE

To evaluate the association of MBIs with reductions in the severity of anxiety in patients with cancer.

DATA SOURCES

Systematic searches of MEDLINE, Embase, Cochrane Central Register of Controlled Trials, CINAHL, PsycINFO, and SCOPUS were conducted from database inception to May 2019 to identify relevant citations.

STUDY SELECTION

Randomized clinical trials (RCTs) that compared MBI with usual care, waitlist controls, or no intervention for the management of anxiety in cancer patients were included. Two reviewers conducted a blinded screening. Of 101 initially identified studies, 28 met the inclusion criteria.

DATA EXTRACTION AND SYNTHESIS

Two reviewers independently extracted the data. The Cochrane Collaboration risk-of-bias tool was used to assess the quality of RCTs, and the Preferred Reporting Items for Systematic Reviews and Meta-analyses reporting guideline was followed. Summary effect measures were reported as standardized mean differences (SMDs) and calculated using a random-effects model.

MAIN OUTCOMES AND MEASURES

Our primary outcome was the measure of severity of short-term anxiety (up to 1-month postintervention); secondary outcomes were the severity of medium-term (1 to ≤6 months postintervention) and long-term (>6 to 12 months postintervention) anxiety, depression, and health-related quality of life of patients and caregivers.

RESULTS

This meta-analysis included 28 RCTs enrolling 3053 adults with cancer. None of the trials were conducted in children. Mindfulness was associated with significant reductions in the severity of short-term anxiety (23 trials; 2339 participants; SMD, -0.51; 95% CI, -0.70 to -0.33; I2 = 76%). The association of mindfulness with short-term anxiety did not vary by evaluated patient, intervention, or study characteristics. Mindfulness was also associated with the reduction of medium-term anxiety (9 trials; 965 participants; SMD, -0.43; 95% CI, -0.68 to -0.18; I2 = 66%). No reduction in long-term anxiety was observed (2 trials; 403 participants; SMD, -0.02; 95% CI, -0.38 to 0.34; I2 = 68%). MBIs were associated with a reduction in the severity of depression in the short term (19 trials; 1874 participants; SMD, -0.73; 95% CI; -1.00 to -0.46; I2 = 86%) and the medium term (8 trials; 891 participants; SMD, -0.85; 95% CI, -1.35 to -0.35; I2 = 91%) and improved health-related quality of life in patients in the short term (9 trials; 1108 participants; SMD, 0.51; 95% CI, 0.20 to 0.82; I2 = 82%) and the medium term (5 trials; 771 participants; SMD, 0.29; 95% CI, 0.06 to 0.52; I2 = 57%).

CONCLUSIONS AND RELEVANCE

In this study, MBIs were associated with reductions in anxiety and depression up to 6 months postintervention in adults with cancer. Future trials should explore the long-term association of mindfulness with anxiety and depression in adults with cancer and determine its efficacy in more diverse cancer populations using active controls.

Mindfulness-Based Cognitive Therapy for Psychological Distress, Fear of Cancer Recurrence, Fatigue, Spiritual Well-Being, and Quality of Life in Patients With Breast Cancer-A Randomized Controlled Trial

CONTEXT

Mindfulness-based interventions have been receiving growing attention in cancer care.

OBJECTIVES

The purpose of this randomized controlled trial is to examine the effectiveness of mindfulness-based cognitive therapy (MBCT) for psychological distress (anxiety and depression), fear of cancer recurrence (FCR), fatigue, spiritual well-being, and quality of life (QOL) in Japanese ambulatory patients with Stage I-III breast cancer.

METHODS

A total of 74 patients were randomly assigned to either an eight-week MBCT intervention group (n = 38) or a wait-list control group (n = 36). The primary outcome was psychological distress, measured on Hospital Anxiety and Depression Scale. The secondary outcomes were FCR (Concerns About Recurrence Scale-overall anxiety subscale), fatigue (Brief Fatigue Inventory), spiritual well-being (Functional Assessment of Chronic Illness Therapy-Spiritual), QOL (Functional Assessment of Cancer Therapy-General), and mindfulness skills (Five Facet Mindfulness Questionnaire). The participants were assessed at baseline (T0), Week 8 (T1), and Week 12 (T2). The results were analyzed using a intention-to-treat linear mixed model.

RESULTS

The participants in the MBCT group experienced significantly better outcomes in their psychological distress (Cohen's d = 1.17; P < 0.001), FCR (d = 0.43; P < 0.05), fatigue (d = 0.66; P < 0.01), spiritual well-being (d = 0.98; P < 0.001), and QOL (d = 0.79; P < 0.001) compared with the control group. The difference remained significant at T2 (four weeks after completion of the intervention).

CONCLUSION

MBCT was demonstrated to improve well-being that encompasses psychological, physical, and spiritual domains in Japanese patients with nonmetastatic breast cancer. The favorable effect was maintained up to four weeks after the completion of the intervention.

The Association Between Mindfulness and Postoperative Pain: A Prospective Cohort Study of Gynecologic Oncology Patients Undergoing Minimally Invasive Hysterectomy

STUDY OBJECTIVE

To describe the association between preoperative dispositional mindfulness (the personality trait of being mindful) and postoperative pain in gynecologic oncology patients undergoing minimally invasive hysterectomy.

DESIGN

Prospective cohort study.

SETTING

University-affiliated teaching hospital.

PATIENTS

Gynecologic oncology patients (n = 126) planning minimally invasive hysterectomy.

INTERVENTIONS

Minimally invasive hysterectomy.

MEASUREMENTS AND MAIN RESULTS

Baseline mindfulness was assessed at the preoperative visit using the Five Facet Mindfulness Questionnaire (FFMQ). Postoperative pain and opioid usage were evaluated via chart review and surveys at postoperative visits at 1 to 2 weeks and 4 to 6 weeks. Higher baseline mindfulness was correlated with lower postoperative pain as measured by both the average and highest numeric pain scores during the inpatient stay (r = -.23, p = .020; r = -.21, p = .034). At the initial postoperative visit, pain score was also inversely correlated with preoperative mindfulness score (r = -.26, p = .008). This relationship was not observed at the final postoperative visit (r = -.08, p = .406). Pre-operative mindfulness and opioid usage were also inversely associated, though this relationship did not reach statistical significance (r = -.18, p = .066).

CONCLUSION

Mindfulness was previously shown to be a promising intervention for chronic pain treatment. Our study demonstrates that higher preoperative dispositional mindfulness is associated with more favorable postoperative pain outcomes, including lower pain scores but not lower opioid consumption. This relationship provides an opportunity to target the modifiable personality characteristic of mindfulness, to reduce postoperative pain in patients following gynecologic surgery.

Online couples mindfulness-based intervention for young breast cancer survivors and their partners: A randomized-control trial

PURPOSE

Young breast cancer survivors (YBCS) face unique challenges in coping with disease, distress, and relationship concerns. The purposes of this study were to understand the acceptability and feasibility of an online Mindfulness-Based Intervention (MBI) for YBCS and their partners (i.e., Couples Mindfulness-Based Intervention: C-MBI) and to compare the effectiveness of the C-MBI to a closely-matched control, an online MBI for individuals (I-MBI).

METHODS

YBCS and their partners were recruited. Couples were randomly assigned to an 8-week C-MBI (couples = 41) or to I-MBI (couples = 36), which included one-hour video modules, a manual, and guided-meditation audios. Both couple members participated in the C-MBI; only the YBCS participated in the control I-MBI. Participants answered surveys about individual- and couple-level functioning at baseline and post-intervention.

RESULTS

Online delivery was shown to be feasible and acceptable. For YBCS and their partners, levels of perceived stress, anxiety, depression, and fatigue were lower after the intervention, in both conditions. Unexpectedly, however, participating in the C-MBI appeared to have detrimental effects on dyadic adjustment and relationship quality.

CONCLUSION

Although YBCS and their partners reported online delivery was acceptable and benefited well-being, for couple-based MBIs to have benefits for relationship functioning, it may be necessary for couples to have the support of other couples and an instructor. Online delivery may be particularly acceptable and effective for clinical populations, including YBCS. Medical professionals may be more likely to recommend online-MBI programs to cancer survivors, because the programs are of little or no cost.

Patient Experience Captured by Quality-of-Life Measurement in Oncology Clinical Trials

IMPORTANCE

Quality of life (QoL) is an important consideration in cancer medicine, especially because drugs are becoming more costly and may only result in modest gains in overall survival. However, there has been no descriptive analysis for the points at which QoL is measured in cancer trials.

OBJECTIVE

To estimate the prevalence of studies that measure QoL at different points and see how many studies measure QoL for the entirety of a patient's life.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional analysis includes all articles on oncology clinical trials in the 3 highest-impact oncology journals, published between July 2015 and June 2018, that reported QoL outcomes.

MAIN OUTCOMES AND MEASURES

Data were abstracted on when QoL was assessed and the characteristics of these studies.

RESULTS

For all 149 studies that met inclusion criteria, QoL assessment was high during treatment (104 articles [69.8%]), during follow-up (81 articles [54.4%]), and after the end of the intervention (68 articles [45.6%]). In 5 of the 149 studies (3.4%), QoL was assessed until death, including in only 1 of the 74 studies on metastatic or incurable cancers. Among these 5 studies, only 1 (20%) used a drug intervention, 1 (20%) used a behavioral intervention, and 2 (40%) used a radiation intervention; only 1 of 5 was in the metastatic setting. The number of studies that reported a positive QoL outcome (ie, QoL outcome was more favorable in the intervention group than in the control group) was between 42 of 81 articles (51.9%) and 16 of 28 articles (57.1%) for most QoL assessment points but only 1 of 5 articles (20%) for studies measuring QoL until death.

CONCLUSIONS AND RELEVANCE

This study found that most clinical trials assessed QoL during the treatment or intervention and often during a given amount of follow-up but infrequently assessed QoL on disease progression and rarely followed QoL until the end of the patient's life. Most studies reporting QoL until the end of life reported worse QoL outcomes for the intervention group than the control group. Future research and policy recommendations should consider not just short-term QoL outcomes but QoL outcomes throughout the patient's cancer care.

Cancer Rehabilitation:: Acute and Chronic Issues, Nerve Injury, Radiation Sequelae, Surgical and Chemo-Related, Part 2

Cancer affects millions of individuals, and approximately half will develop functional impairments. Cancers that commonly, either from direct effects or from its treatments, result in functional impairments include breast, head and neck, brain, and spinal cord tumors. There is a plethora of potential impairments including pain, spasticity, dystonia, weakness, and neurogenic bowel or bladder. This article reviews the functional impairments frequently encountered in breast, head and neck, brain, and spinal cord tumors. The authors also discuss management and treatment options incorporated in comprehensive cancer rehabilitation to address these impairments to maximize and maintain function and quality of life.

Psychosocial Interventions for Pain Management in Advanced Cancer Patients: a Systematic Review and Meta-analysis

Purpose of Review

This systematic review and meta-analysis aimed to synthesize the evidence on the effects of psychosocial interventions on pain in advanced cancer patients.

Recent Findings

The included studies investigated the effects of relaxation techniques, cognitive-behavioral therapy, music therapy, mindfulness- and acceptance-based interventions, and supportive-expressive group therapy. Overall, we found a small, but significant effect on pain intensity (d = − 0.29, CI = − 0.54 to − 0.05). Effect sizes were highly heterogeneous between studies. We did not find evidence for the superiority of any of the intervention types. However, psychosocial interventions may be more effective if they specifically targeted pain distress as the primary outcome.

Summary

Although findings were mixed, psychosocial interventions can be recommended to complement comprehensive care to alleviate pain in patients facing an advanced or terminal stage of the disease. Future research should develop innovative interventions tailored specifically for pain relief.

Effect of complementary and alternative medicine interventions on cancer related pain among breast cancer patients: A systematic review

OBJECTIVE

This systematic review aimed to evaluate the efficacy of CAM interventions for cancer-related pain in breast cancer patients.

METHODS

Databases (PubMed, Scopus, Web of Science, and EMBASE) were searched from January 1, 2000, up to April 31, 2019, using the keywords: Complementary and alternative medicine therapies and cancer related pain. Standard tools were used to evaluate the quality of the studies included.

RESULTS

Of the 3742 articles found, 46 articles comprising 3685 participants entered the final phase. Our results indicate that interventions including acupuncture/acupressure, tai chi/qi gong, hypnosis, meditation, music therapy, yoga, massage, reflexology, and Reiki improve cancer-related pain in breast cancer patients. However, aromatherapy had no effect on the same.

CONCLUSIONS

Despite the positive effect of various CAM interventions in reducing cancer-related pain, necessary precautions should be adopted to use them alongside other treatments to control cancer pain in the clinical setting.

The Effectiveness of Psychological Treatments in Women with Breast Cancer: A Systematic Review and Meta-Analysis

Breast cancer is the most prevalent oncological disease among women, and it represents the second oncological cause of death. Many studies have considered the quality of life in people with breast cancer because this condition has high comorbidity with mental distress, anxiety, affective disorders and depression. Psychological interventions can reduce the stressful consequences of both the diagnosis and the medical treatments of breast cancer. However, different methods (e.g., group or individual therapy) and focus (e.g., improving personal skills or increasing emotional well-being) do not help to identify which type of psychological therapy can be more effective in improving quality of life in patients with breast cancer. This study was aimed to systematically review and compare, by means of a meta-analysis, the efficacy of cognitive behavioural, supportive-expressive or psycho-educational treatments in women with breast cancer, focusing on anxiety, depression, mood and quality of life as outcomes. The PRISMA statement was adopted. MEDLINE, PsycINFO, PUBMED and PsycArticles databases were used, and reference lists were examined for additional publications. In the selection of the articles were included studies considering women between 18 and 65 years who were diagnosed with breast cancer at any stage and under any treatment, and who underwent psychological group interventions. At the end of the systematic review, 45 studies met all inclusion criteria and were analysed in the meta-analysis. The overall effect size was medium, especially considering cognitive behavioural therapy and psycho-educational treatments. However, the studies are characterised by high methodological heterogeneity. Despite some limitations, this review and meta-analysis partially confirm the efficiency of cognitive-behavioural and psycho-educational therapies in the improvement of well-being in women with breast cancer.

Acupuncture for Cancer Related Pain: Protocol for a Pragmatic Randomised Wait-List Controlled Trial

BACKGROUND

Acupuncture has been proved effective for cancer related pain (CRP) in China, America and some other countries. However, there is relative lack of evidence to support the use of acupuncture for CRP in Australia.

OBJECTIVES

To assess the effectiveness and safety of acupuncture for management of CRP in a real-world setting and to understand cancer patients' experience of undergoing acupuncture for CRP.

METHODS

A pragmatic randomised controlled trial will be conducted in South Western Sydney Local Health District (SWSLHD) in NSW, Australia. Adults with cancer related pain (n = 106) will be randomised in a 1:1 ratio to receive the acupuncture intervention up front versus after a wait list period of 4 weeks. Pain level (by Numerical Rating Scale), analgesic use, auricular acupressure frequency and adverse events will be assessed at baseline, mid-treatment and post-treatment. Expectancy on trial outcome (by Credibility and Expectancy questionnaire) will be assessed at baseline. The perspective of the participants (by an interview) will be recorded after the last intervention.

EXPECTED OUTCOMES

We hypothesise that acupuncture will relieve cancer related pain at mid-treatment and post-treatment. We also hypothesise that few adverse events will be provoked by acupuncture.

Mindfulness-based cognitive therapy and cognitive behavioral therapy for chronic pain in multiple sclerosis: a randomized controlled trial protocol

BACKGROUND

Chronic pain is one of the most prevalent and disabling symptoms associated with multiple sclerosis (MS). Individuals with MS are interested in nonpharmacologic pain management approaches. Cognitive-behavioral therapy (CBT) is efficacious in improving MS-related pain outcomes. Mindfulness-based cognitive therapy (MBCT) is a promising, alternative approach. Little is known about moderators of these treatments' outcomes, however. This article describes the study protocol for the first randomized controlled trial comparing MBCT, CBT, and usual care and examining treatment effect moderators in individuals with chronic pain and MS.

METHODS

We will conduct a single-center, randomized, single blind, parallel-group trial comparing MBCT, CBT, and usual care in adults with MS and chronic pain. Both interventions will be delivered via eight group sessions using videoconferencing technology. Primary (average pain intensity) and secondary outcomes (including pain interference, depressive symptoms, fatigue, and sleep) will be assessed pre-treatment, mid-treatment, post-treatment, and at 6-month follow up. Potential treatment moderators will be assessed pre-treatment. We hypothesize that participants randomly assigned to MBCT or CBT will report significantly greater reductions in average pain intensity than participants assigned to usual care at post-treatment (primary study endpoint) and 6-month follow up. We also hypothesize that mindfulness, pain catastrophizing, and behavioral activation pre-treatment will moderate response to both active treatments, but not response to usual care.

DISCUSSION

Findings will provide important new information about the efficacy and moderators of two nonpharmacologic pain management approaches delivered using technology to overcome common barriers to treatment access. The knowledge gained may lead to better patient-treatment matching and, ultimately, better pain treatment outcomes in MS.
