Examination of Broad Symptom Improvement Resulting From Mindfulness-Based Stress Reduction in Breast Cancer Survivors: A Randomized Controlled Trial

Health anxiety and illness-related fears across diverse chronic illnesses: A systematic review on conceptualization, measurement, prevalence, course, and correlates

BACKGROUND

Patients with chronic diseases commonly report fears of illness or symptoms recurring or worsening. These fears have been addressed from an illness-specific perspective (e.g., fear of cancer recurrence), a generic illness perspective (e.g., fear of progression), and a psychiatric perspective (DSM-5 illness anxiety disorder and somatic symptom disorder). The broader concept of health anxiety (HA) can also be applied to patients with a chronic disease. This review was conducted to investigate the conceptual, theoretical, measurement-overlap, and differences between these distinct perspectives. We also aimed to summarize prevalence, course, and correlates of these fears in different chronic illnesses.

METHODS

We used PsycINFO, PubMED, CINAHL, Web of Science, SCOPUS, and PSYNDEX to conduct a systematic review of studies pertaining to these fears in chronic illness published from January 1996 to October 2017. A total of 401 articles were retained.

RESULTS

There were commonalities across different conceptualizations and diseases: a high prevalence of clinical levels of fears (>20%), a stable course over time, and a deleterious impact on quality of life. Reviewed studies used definitions, models, and measures that were illness-specific, with only a minority employing a psychiatric perspective, limiting cross-disease generalizability. There appears to be some applicability of DSM-5 disorders to the experience of fear of illness/symptoms in patients with a chronic illness. While conceptualizing HA on a continuum ranging from mild and transient to severe may be appropriate, there is a lack of agreement about when the level of fear becomes 'excessive.' The definitions, models, and measures of HA across chronic illnesses involve affective, cognitive, behavioral, and perceptual features.

CONCLUSIONS

The concept of HA may offer a unifying conceptual perspective on the fears of illness/symptoms worsening or returning commonly experienced by those with chronic disease.

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.

Age moderates the association between psychological distress and engagement in mindfulness among cancer patients and survivors: A population-based study

PURPOSE

We aim to evaluate the relationship between psychological distress and engagement in mindfulness among a national representative sample of cancer survivors.

SAMPLE AND DESIGN

Using the 2017 National Health Interview Survey, our final analytical sample included 3068 participants who reported having been diagnosed with cancer.

METHODS AND ANALYSIS

We used logistic regression analysis to assess the association and to test age as a moderator. We also conducted follow-up analysis using Fisher's r-to-z transformation. All analyses were adjusted for complex sample weights.

FINDINGS

Cancer survivors who had subclinical and clinical psychological distress were more likely to engage in mindfulness, OR = 1.59, 95% CI [1.24, 2.02] and OR = 1.45, 95% CI [1.02, 2.05], respectively. Age significantly moderated such association with the relationship much stronger among those who are younger (younger than 65 years old) than those who are older (65 years or older), b = 0.97, 95% CI [0.95, 0.99].

CONCLUSIONS

The relationship between psychological distress and engagement in mindfulness differs significantly by a survivor's age. Psychosocial oncological providers need to account for a survivor's age when delivering mindfulness based care to address psychological distress.

IMPLICATIONS

Providers should be mindful of a survivor's age when recommending mindfulness oriented practices.

Radiotherapy side effects: integrating a survivorship clinical lens to better serve patients

The Canadian Cancer Society estimated that 220,400 new cases of cancer would be diagnosed in 2019. Of the affected patients, more than 60% will survive for 5 years or longer after their cancer diagnosis. Furthermore, nearly 40% will receive at least 1 course of radiotherapy (rt). Radiotherapy is used with both curative and palliative intent: to treat early-stage or locally advanced tumours (curative) and for symptom management in advanced disease (palliative). It can be delivered systemically (external-beam rt) or internally (brachytherapy). Although technique improvements have drastically reduced the occurrence of rt-related toxicity, most patients still experience burdensome rt side effects (seffs). Radiotherapy seffs are local or locoregional, and manifest in tissues or organs that were irradiated. Side effects manifesting within weeks after rt completion are termed "early seffs," and those occurring months or years after treatment are termed "late seffs." In addition to radiation oncologists, general practitioners in oncology and primary care providers are involved in survivorship care and management of rt seffs. Here, we present an overview of common seffs and their respective management: anxiety, depression, fatigue, and effects related to the head-and-neck, thoracic, and pelvic treatment sites.

Long-Term Effect of a Nonrandomized Psychosocial Mindfulness-Based Intervention in Hispanic/Latina Breast Cancer Survivors

Background: There is a paucity of research on the long-term impact of stress-reduction in Hispanic/Latina breast cancer (BC) survivors, a growing minority. In this article, we assess the long-term efficacy of an 8-week training program in mindfulness-based stress reduction (MBSR) on quality of life (QoL) in Hispanic BC survivors. Methods: Hispanic BC survivors, within the first 5 years of diagnosis, stages I to III BC, were recruited. Participants were enrolled in bilingual, 8-week intensive group training in MBSR and were asked to practice a- home, daily. They were also provided with audio recordings and a book on mindfulness practices. Patient-reported outcomes for QoL and distress were evaluated at baseline, and every 3 months, for 24 months. Results: Thirty-three self-identified Hispanic women with BC completed the MBSR program and were followed at 24 months. Statistically significant reduction was noted for the Generalized Anxiety Disorder measure (mean change −2.39, P=0.04); and Patient Health Questionnaire (mean change −2.27, P=0.04), at 24 months, compared with baseline. Improvement was noted in the Short-Form 36 Health-related QoL Mental Component Summary with an increase of 4.07 (95% confidence interval = 0.48-7.66, P=0.03). However, there was no significant change in the Physical Component Summary. Conclusions: Hispanic BC survivors who participated in an 8-week MBSR–based survivorship program reported persistent benefits with reduced anxiety, depression, and improved mental health QoL over 24 months of follow-up. Stress reduction programs are beneficial and can be implemented as part of a comprehensive survivorship care in BC patients.

Palliative Care and the Management of Common Distressing Symptoms in Advanced Cancer: Pain, Breathlessness, Nausea and Vomiting, and Fatigue

Good symptom management in oncology is associated with improved patient and family quality of life, greater treatment compliance, and may even offer survival advantages. With population growth and aging, the proportion of patients with multiple symptoms-both related and unrelated to their cancer-is anticipated to increase, supporting calls for a more routine and integrated approach to symptom management. This article presents a summary of the literature for the use of symptom assessment tools and reviews the management of four common and distressing symptoms commonly experienced by people with advanced cancer: pain, breathlessness, nausea and vomiting, and fatigue. We also discuss the role of palliative care in supporting a holistic approach to symptom management throughout the cancer trajectory.

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.

Embracing the complexity: Older adults with cancer-related cognitive decline-A Young International Society of Geriatric Oncology position paper

Cancer-related cognitive decline (CRCD) may have particularly significant consequences for older adults, impacting their functional and physical abilities, level of independence, ability to make decisions, treatment adherence, overall quality of life, and ultimately survival. In honor of Dr. Hurria's work we explore and examine multiple types of screening, assessment and non-pharmacologic treatments for CRCD. We then suggest future research and clinical practice questions to holistically appreciate the complexity of older adults with cancer's experiences and fully integrate the team-based approach to best serve this population.

Mindfulness-based stress reduction can alleviate cancer- related fatigue: A meta-analysis

OBJECTIVES

The purpose of this meta-analysis was to critically evaluate the effects of mindfulness-based stress reduction (MBSR) on cancer-related fatigue (CRF).

METHODS

A systematic search of eight databases (Web of Science, Pubmed, Cochrane Library, Spring link, CNKI, Wanfang, VIP, CBM) was performed, to find randomized controlled trials (RCTs) from inception to January 2019. Using Cochrane Collaboration criteria, two reviewers critically and independently assessed the risk of bias and extracted correlated data using the designed form. All analyses were performed with Review Manager 5.3.

RESULTS

In all, fifteen RCTs were included in the systematic review, fourteen of which, consisting of 3008 patients (MBSR, 1502; control, 1506), were included in the meta-analysis. MBSR had a significant effect on fatigue in cancer patients, particularly among lung cancer patients. The meta-analysis also indicated that MBSR could significantly mitigate CRF compared with usual care or no intervention. 8 weeks of MBSR, supervised by experts, had a large effect on CRF.

CONCLUSIONS

MBSR is effective for CRF management and can be recommended as a beneficial complementary therapy for CRF patients.

A randomized pilot study of mindfulness-based stress reduction in a young adult cancer sample: Feasibility, acceptability, and changes in patient reported outcomes

BACKGROUND

The primary purpose of this study was to examine the feasibility and acceptability of participation in a randomized waitlist-controlled intervention of mindfulness-based stress reduction (MBSR) in a young adult cancer sample. A secondary aim was to examine patterns of change in patient reported outcomes (PROs) of physical, social, and emotional functioning.

METHODS

Participants were enrolled at a large Midwestern comprehensive cancer center and randomized to MBSR or a waitlist control. Feasibility and acceptability were examined through enrollment metrics and a survey. PROs were gathered at baseline, 8-weeks, and 16-weeks. Descriptive statistics and mixed models were used in analyses.

RESULTS

Of 597 eligible participants, 151 (26.5%) consented from which 126 (83.4%) completed baseline measures. Sixty-seven participants were randomized to MBSR, and 59 to the waitlist. Immediately following MBSR, the majority of respondents (72%-78%) reported their experience with mindfulness was very logical and useful to increasing their wellbeing. Compared to waitlist members, MBSR participant's scores on PROs improved in expected directions.

CONCLUSIONS

Our findings suggest that recruitment for an intensive, in-person, multi-week supportive intervention can be challenging with young adults with cancer, similar to other cancer survivor populations; however once enrolled, feasibility and acceptability of MBSR was supported. Further, initial evidence on the role of MBSR on short-term changes in select PROs with this population was also demonstrated.

The relation between mindfulness and the fatigue of women with breast cancer: path analysis

Background

Although fatigue is a common and distressing symptom in cancer survivors, the mechanism of fatigue is not fully understood. Therefore, this study aims to investigate the relation between the fatigue and mindfulness of breast cancer survivors using anxiety, depression, pain, loneliness, and sleep disturbance as mediators.

Methods

Path analysis was performed to examine direct and indirect associations between mindfulness and fatigue. Participants were breast cancer survivors who visited a breast surgery department at a university hospital in Japan for hormonal therapy or regular check-ups after treatment. The questionnaire measured cancer-related-fatigue, mindfulness, anxiety, depression, pain, loneliness, and sleep disturbance. Demographic and clinical characteristics were collected from medical records.

Results

Two-hundred and seventy-nine breast cancer survivors were registered, of which 259 answered the questionnaire. Ten respondents with incomplete questionnaire data were excluded, resulting in 249 participants for the analyses. Our final model fit the data well (goodness of fit index = .993; adjusted goodness of fit index = .966; comparative fit index = .999; root mean square error of approximation = .016). Mindfulness, anxiety, depression, pain, loneliness, and sleep disturbance were related to fatigue, and mindfulness had the most influence on fatigue (β = − .52). Mindfulness affected fatigue not only directly but also indirectly through anxiety, depression, pain, loneliness, and sleep disturbance.

Conclusions

The study model helps to explain the process by which mindfulness affects fatigue. Our results suggest that mindfulness has both direct and indirect effects on the fatigue of breast cancer survivors and that mindfulness can be used to more effectively reduce their fatigue. It also suggests that health care professionals should be aware of factors such as anxiety, depression, pain, loneliness, and sleep disturbance in their care for fatigue of breast cancer survivors.

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.

The Effect of Mindfulness-Based Stress Reduction Group Counseling on Psychological and Inflammatory Responses of the Women With Breast Cancer

Introduction: Breast cancer is common among women and reduces their quality of life. The current study aimed to investigate the effectiveness of mindfulness-based stress reduction group counseling in alleviating psychological responses such as anxiety, depression, stress, and regulating laboratory tests including cortisol and C-reactive protein (CRP) in women with breast cancer. Methods: This randomized clinical trial was conducted based on convenience sampling. Participants were divided into 2 groups (control and intervention groups) with block randomization. The intervention group received mindfulness-based stress reduction group counseling during 8 weeks. The participants completed the Beck anxiety inventory, Beck-II depression inventory, and perceived stress scale before and after the intervention and their blood samples were taken to check their cortisol and CRP. Results: After the intervention, the MBSR group had significantly lower anxiety compared with the control group (P < .001). No significant difference was found between the 2 groups in the reduction of perceived stress and depression (P < .05). In addition, no significant difference was found between the 2 groups in CRP and cortisol levels after the intervention (P > .05). Conclusion: The present study showed the effectiveness of mindfulness-based cognitive therapy in improving anxiety rather than the stress, depression, and inflammatory laboratory factors such as cortisol and CRP in women with breast cancer. Therefore, the psychological symptoms of these patients can be improved at different stages of treatment by providing this type of training.

The effectiveness of psychological interventions for fatigue in cancer survivors: systematic review of randomised controlled trials

BACKGROUND

Fatigue is a common symptom in cancer patients that can persist beyond the curative treatment phase. This systematic review evaluated the effectiveness of psychological interventions for cancer-related fatigue in post-treatment cancer survivors.

METHODS

We searched relevant online databases and sources of grey literature. Randomised controlled trials (RCTs) evaluating psychological interventions in adult cancer patients after the completion of treatment, with fatigue as an outcome measure, were included. Two review authors extracted data independently from the selected studies and assessed the methodological quality using the Cochrane Collaboration Risk of Bias Tool.

RESULTS

Thirty-three psychological interventions were identified. The sample size of the included studies varied between 28 and 409, with 4525 participants overall. Twenty-three of the included studies reported a significant effect of the interventions on reducing fatigue in cancer survivors. Most interventions focused on psychoeducation, mindfulness, cognitive or behaviour therapy-oriented strategies. However, studies differed widely in terms of measurement tools used to assess fatigue, mode, duration and frequency of the intervention delivery.

CONCLUSIONS

This review showed some tentative support for psychological interventions for fatigue after cancer treatment. However, as the RCTs were heterogeneous in nature and the number of high-quality studies was limited, definitive conclusions are not yet possible. With the growing need for stage-specific research in cancer, this review sought to inform current practice and to summarise the existing evidence base of randomised controlled trials in the area.

Study protocol of the BLANKET trial: a cluster randomised controlled trial on the (cost-) effectiveness of a primary care intervention for fear of cancer recurrence in cancer survivors

INTRODUCTION

Many successfully treated patients with cancer suffer from fear of cancer recurrence (FCR), affecting their quality of life and their physical, emotional, cognitive and social functioning. Effective psychological interventions for FCR exist but are not widely available, as they are typically offered by specialised psycho-oncology professionals and institutes. Concurrently, the role of primary care in cancer and survivorship care is increasing. Therefore, there could be a role for general practitioners (GPs) and mental health workers (MHWs) working in primary care in supporting patients with FCR. In the current study, the effectiveness of a primary care delivered FCR intervention will be evaluated.

METHODS AND ANALYSIS

A two-armed cluster randomised trial will be conducted. The primary outcome will be FCR severity; secondary outcomes will be FCR-related distress, healthcare uptake and healthcare costs. Primary care practices in the Netherlands will be invited to participate in the study. Participating practices will be stratified by size and socioeconomic status and randomised. In the control arm, practices will provide care as usual. In the intervention arm, practices will offer the cognitive-behavioural FCR intervention that is being studied, which consists of an intake with the GP and five sessions with the MHW. Patients who have finished successful curative treatment for cancer between 3 months and 10 years ago will be invited to participate in the study by invitation letter from their GPs. Participating patients will fill out questionnaires at baseline, after 3 months and after 12 months. Data on healthcare use will be collected from their electronic health records. Qualitative interviews are held at T1 with patients and practitioners in the intervention group.

ETHICS AND DISSEMINATION

The Medical Research Ethics Committee (METC) Utrecht has reviewed the study in accordance with the Dutch Medical Research Involving Human Subjects Act (WMO) and other applicable Dutch and European regulations. Based on the requirements of the WMO, the METC Utrecht has issued an approval of the above-mentioned study. Any protocol amendments will be communicated to all relevant parties. Written consent is obtained from study participants. Results will be dispersed through peer-reviewed publications and scientific presentations.

Development of the Therapeutic Alliance and its Association With Internet-Based Mindfulness-Based Cognitive Therapy for Distressed Cancer Patients: Secondary Analysis of a Multicenter Randomized Controlled Trial

Background

Mindfulness-based cognitive therapy (MBCT) is an evidence-based group-based psychological treatment in oncology, resulting in reduction of depressive and anxiety symptoms. Internet-based MBCT (eMBCT) has been found to be an effective alternative for MBCT. The therapeutic alliance (the bond between therapist and patient,) is known to have a significant impact on psychological treatment outcomes, including MBCT. A primary concern in the practice of eMBCT is whether a good therapeutic alliance can develop. Although evidence for the beneficial effect of therapist assistance on treatment outcome in internet-based interventions (IBIs) is accumulating, it is still unclear whether the therapeutic alliance is related to outcome in IBIs.

Objective

This study aimed to (1) explore whether early therapeutic alliance predicts treatment dropout in MBCT or eMBCT, (2) compare the development of the therapeutic alliance during eMBCT and MBCT, and (3) examine whether early therapeutic alliance is a predictor of the reduction of psychological distress and the increase of mental well-being at posttreatment in both conditions.

Methods

This study was part of a multicenter randomized controlled trial (n=245) on the effectiveness of MBCT or eMBCT for distressed cancer patients. The therapeutic alliance was measured at the start of week 2 (ie, early therapeutic alliance), week 5, and week 9. Outcome measures were psychological distress, measured with the Hospital Anxiety and Depression Scale, and mental well-being, measured with the Mental Health Continuum-Short Form.

Results

The strength of early therapeutic alliance did not predict treatment dropout in MBCT or eMBCT (B=−.39; P=.21). Therapeutic alliance increased over time in both conditions (F_2,90=16.46; Wilks λ=0.732; P<.001). This increase did not differ between eMBCT and MBCT (F_1,91=0.114; P=.74). Therapeutic alliance at week 2 predicted a decrease in psychological distress (B=−.12; t₁₁₄=−2.656; P=.01) and an increase in mental well-being (B=.23; t₁₁₃=2.651; P=.01) at posttreatment. The relationship with reduction of psychological distress differed between treatments: a weaker early therapeutic alliance predicted higher psychological distress at posttreatment in MBCT but not in eMBCT (B=.22; t₁₁₃=2.261; P=.03).

Conclusions

A therapeutic alliance can develop in both eMBCT and MBCT. Findings revealed that the strength of early alliance did not predict treatment dropout. Furthermore, the level of therapeutic alliance predicted reduced psychological distress and increased mental well-being at posttreatment in both conditions. Interestingly, the strength of therapeutic alliance appeared to be more related to treatment outcome in group-based MBCT than in eMBCT.

Yoga intervention and reminder e-mails for reducing cancer-related fatigue - a study protocol of a randomized controlled trial

Background

Almost 90% of cancer patients suffer from symptoms of fatigue during treatment. Supporting treatments are increasingly used to alleviate the burden of fatigue. This study examines the short-term and long-term effects of yoga on fatigue and the effect of weekly reminder e-mails on exercise frequency and fatigue symptoms.

Methods

The aim of the first part of the study will evaluate the effectiveness of yoga for cancer patients with mixed diagnoses reporting fatigue. We will randomly allocate 128 patients to an intervention group (N = 64) receiving yoga and a wait-list control group (N = 64) receiving yoga 9 weeks later. The yoga therapy will be performed in weekly sessions of 60 min each for 8 weeks. The primary outcome will be self-reported fatigue symptoms. In the second part of the study, the effectiveness of reminder e-mails with regard to the exercise frequency and self-reported fatigue symptoms will be evaluated. A randomized allocated group of the participants (“email”) receives weekly reminder e-mails, the other group does not. Data will be assessed using questionnaires the beginning and after yoga therapy as well as after 6 months.

Discussion

Support of patients suffering from fatigue is an important goal in cancer patients care. If yoga therapy will reduce fatigue, this type of therapy may be introduced into routine practice. If the reminder e-mails prove to be helpful, new offers for patients may also develop from this.

Effect of Psychological Intervention on Fear of Cancer Recurrence: A Systematic Review and Meta-Analysis

PURPOSE

Fear of cancer recurrence (FCR) is a significantly distressing problem that affects a substantial number of patients with and survivors of cancer; however, the overall efficacy of available psychological interventions on FCR remains unknown. We therefore evaluated this in the present systematic review and meta-analysis.

METHODS

We searched key electronic databases to identify trials that evaluated the effect of psychological interventions on FCR among patients with and survivors of cancer. Controlled trials were subjected to meta-analysis, and the moderating influence of study characteristics on the effect were examined. Overall quality of evidence was evaluated using the GRADE system. Open trials were narratively reviewed to explore ongoing developments in the field (PROSPERO registration no.: CRD42017076514).

RESULTS

A total of 23 controlled trials (21 randomized controlled trials) and nine open trials were included. Small effects (Hedges’s g) were found both at postintervention (g = 0.33; 95% CI, 0.20 to 0.46; P < .001) and at follow-up (g = 0.28; 95% CI, 0.17 to 0.40; P < .001). Effects at postintervention of contemporary cognitive behavioral therapies (CBTs; g = 0.42) were larger than those of traditional CBTs (g = 0.24; β = .22; 95% CI, .04 to .41; P = .018). At follow-up, larger effects were associated with shorter time to follow-up (β = −.01; 95% CI, −.01 to −.00; P = .027) and group-based formats (β = .18; 95% CI, .01 to .36; P = .041). A GRADE evaluation indicated evidence of moderate strength for effects of psychological intervention for FCR.

CONCLUSION

Psychological interventions for FCR revealed a small but robust effect at postintervention, which was largely maintained at follow-up. Larger postintervention effects were found for contemporary CBTs that were focused on processes of cognition—for example, worry, rumination, and attentional bias—rather than the content, and aimed to change the way in which the individual relates to his or her inner experiences. Future trials could investigate how to further optimize and tailor interventions to individual patients’ FCR presentation.

Mindfulness-based interventions for psychological and physical health outcomes in cancer patients and survivors: A systematic review and meta-analysis of randomized controlled trials

OBJECTIVE

Mindfulness-based interventions (MBIs) are increasingly used within psycho-oncology. Since the publication of the most recent comprehensive meta-analysis on MBIs in cancer in 2012, the number of published trials has more than doubled. We therefore conducted a systematic review and meta-analysis of randomized controlled trials (RCTs), testing the efficacy of MBIs on measures of psychological distress (primary outcome) and other health outcomes in cancer patients and survivors.

METHODS

Two authors conducted independent literature searches in electronic databases from first available date to 10 October 2018, selected eligible studies, extracted data for meta-analysis, and evaluated risk of bias.

RESULTS

Twenty-nine independent RCTs (reported in 38 papers) with 3274 participants were included. Small and statistically significant pooled effects of MBIs on combined measures of psychological distress were found at post-intervention (Hedges's g = 0.32; 95%CI: 0.22-0.41; P < .001) and follow-up (g = 0.19; 95%CI: 0.07-0.30; P < .002). Statistically significant effects were also found at either post-intervention or follow-up for a range of self-reported secondary outcomes, including anxiety, depression, fear of cancer recurrence, fatigue, sleep disturbances, and pain (g: 0.20 to 0.51; p: <.001 to.047). Larger effects of MBIs on psychological distress were found in studies (a) adhering to the original MBI manuals, (b) with younger patients, (c) with passive control conditions, and (d) shorter time to follow-up. Improvements in mindfulness skills were associated with greater reductions in psychological distress at post-intervention.

CONCLUSIONS

MBIs appear efficacious in reducing psychological distress and other symptoms in cancer patients and survivors. However, many of the effects were of small magnitude, suggesting a need for intervention optimization research.

Resilience and coping styles as predictors of health outcomes in breast cancer patients: A structural equation modelling analysis

INTRODUCTION

Resilience has been associated with psychological adaptation to many threatening life events, but previous studies have rarely analysed the integrated relationships among demographic and disease characteristics and various health outcomes in Taiwan. This study examined the associations among demographic factors, disease characteristics, resilience, coping styles and adverse health outcomes, including anxiety and depressive symptoms and sleep disorders.

METHODS

A descriptive, cross-sectional study design was used. Data from a convenience sample of 175 patients with breast cancer aged 20 years or older were collected using a self-reported questionnaire. A structural equation modelling approach was applied to examine the relationships among the variables.

RESULTS

The results showed that greater resilience was related to fewer depressive symptoms, lower anxiety levels and better sleep quality. All three coping styles, including active coping, minimising the situation and avoidance coping, were negatively correlated with depressive symptoms, but only active coping was significantly correlated with sleep quality. Resilience had a direct effect on depressive symptoms, anxiety and sleep disorders. Furthermore, a mediating effect of resilience was observed on the relationship between marital satisfaction and depressive symptoms.

CONCLUSION

Resilience can strengthen breast cancer-related adaptation. Additionally, breast cancer survivors who used mainly the active and minimising coping styles tended to experience fewer depressive symptoms.

Mindfulness Training Supports Quality of Life and Advance Care Planning in Adults With Metastatic Cancer and Their Caregivers: Results of a Pilot Study

BACKGROUND

Emotional distress often causes patients with cancer and their family caregivers (FCGs) to avoid end-of-life discussions and advance care planning (ACP), which may undermine quality of life (QoL). Most ACP interventions fail to address emotional barriers that impede timely ACP.

AIM

We assessed feasibility, acceptability, and preliminary effects of a mindfulness-based intervention to facilitate ACP for adults with advanced-stage cancer and their FCGs.

DESIGN

A single-arm pilot was conducted to assess the impact of a 6-week group mindfulness intervention on ACP behaviors (patients only), QoL, family communication, avoidant coping, distress, and other outcomes from baseline (T1) to post-intervention (T2) and 1 month later (T3).

PARTICIPANTS

Eligible patients had advanced-stage solid malignancies, limited ACP engagement, and an FCG willing to participate. Thirteen dyads (N = 26 participants) enrolled at an academic cancer center in the United States.

RESULTS

Of eligible patients, 59.1% enrolled. Attendance (70.8% across 6 sessions) and retention (84.6% for patients; 92.3% for FCGs) through T3 were acceptable. Over 90% of completers reported high intervention satisfaction. From T1 to T3, patient engagement more than doubled in each of 3 ACP behaviors assessed. Patients reported large significant decreases in distress at T2 and T3. Family caregivers reported large significant improvements in QoL and family communication at T2 and T3. Both patients and FCGs reported notable reductions in sleep disturbance and avoidant coping at T3.

CONCLUSIONS

The mindfulness intervention was feasible and acceptable and supported improvements in ACP and associated outcomes for patients and FCGs. A randomized trial of mindfulness training for ACP is warranted. The study is registered at ClinicalTrials.gov with identifier NCT02367508 ( https://clinicaltrials.gov/ct2/show/NCT02367508 ).

Effects of mindfulness-based interventions on quality of life of women with breast cancer: a systematic review

Aim: The systematic review assessed the effect of mindfulness-based interventions on the quality of life among women with breast cancer. Methods: PubMed, Cochrane library, EMBASE, Web of Science and CINAHL databases were searched for studies published. Our review assessed the effect of mindfulness-based interventions (Mindfulness-Based Stress Reduction [MBSR] intervention and Mindfulness-Based Cognitive Therapy [MBCT]) on quality of life for women with breast cancer. Two authors independently assessed the quality of all included studies using the Downs and Black Quality Index. Results: The search finally identified 15 studies. The MBSR intervention showed a significant effect between groups. The MBCT intervention also showed good effect on quality of life. Adverse events were inadequately reported. Conclusion: The MBSR intervention on quality of life among women with breast cancer was effective and safe. The effect of MBCT intervention on quality of life still needs more research.

Translational genomic research: the role of genetic polymorphisms in MBSR program among breast cancer survivors (MBSR[BC])

Genetic variations of breast cancer survivors (BCS) may contribute to level of residual symptoms, such as depression, stress, fatigue, and cognitive impairment. The objective of this study was to investigate whether particular single-nucleotide polymorphisms (SNPs) moderated symptom improvement resulting from the Mindfulness-Based Stress Reduction for Breast Cancer (MBSR[BC]) program. An overarching goal of personalized medicine is to identify individuals as risk for disease and tailor interventions based on genetic profiles of patients with diseases including cancer. BCS were recruited from Moffitt Cancer Center and University of South Florida's Breast Health Program and were randomized to either the 6-week MBSR(BC) program (n = 92) or Usual Care (n = 93). Measures of symptoms, demographic, and clinical history data were attained at baseline, 6 weeks, and 12 weeks. A total of 10 SNPs from eight genes known to be related to these symptoms were studied using genomic DNA extracted from blood. Our results were examined for effect sizes, consistency, and statistical significance (p < .05). Three SNPs (rs4680 in COMT, rs6314 in HTR2A, and rs429358 in APOE) emerged as having the strongest (though relatively weak) and most consistent effects in moderating the impact of the MBSR program on symptom outcomes. Although effects were generally weak, with only one effect withstanding multiple comparisons correction for statistical significance, this translational behavioral research may help start the identification of genetic profiles that moderate the impact of MBSR(BC). The ultimate goal of this study is the development of personalized treatment programs tailored to the genetic profile of each patient.

Mind-body medicine use by women diagnosed with breast cancer: results of a nationally representative survey

PURPOSE

Worldwide breast cancer is the most commonly diagnosed cancer in women and often associated with a profound physiological stress reaction. Mind-body medicine modalities have been proven effective in reducing stress symptoms. This article will cover the prevalence of MBM use in women with and without breast cancer in the US population and detect predictors of MBM use in women diagnosed with breast cancer.

METHODS

The 2017 National Health Interview Survey (NHIS) was used to study the prevalence of breast cancer and the use of mind-body medicine (MBM) among individuals with breast cancer in the US population. Using chi-squared tests and backward stepwise multiple logistic regression analyses, predictors of MBM use in women with breast cancer in the past 12 months were identified.

RESULTS

The prevalence of breast cancer in women was 3.1%. Among women diagnosed with breast cancer, 25.2% had used MBM in the past 12 months. Spiritual meditation (14.3%), followed by yoga (9.6%), and mindfulness meditation (4.3%) were the most commonly used MBM approaches for women with breast cancer diagnosis. Only higher education independently predicted the use of MBM among them.

CONCLUSIONS

In this nationally representative sample of the USA, the most common used MBM approach was spiritual meditation, while this approach is much less researched than the evidence based approaches of yoga and mindfulness meditation. Especially stressed individuals worldwide could benefit from MBM the literature suggests. Particularly in the acute survivorship stage, influencing the initial stress reaction could be beneficial.

Mindfulness-based stress reduction for women diagnosed with breast cancer

BACKGROUND

Breast cancer is the most common cancer in women. Diagnosis and treatment may drastically affect quality of life, causing symptoms such as sleep disorders, depression and anxiety. Mindfulness-based stress reduction (MBSR) is a programme that aims to reduce stress by developing mindfulness, meaning a non-judgmental, accepting moment-by-moment awareness. MBSR seems to benefit patients with mood disorders and chronic pain, and it may also benefit women with breast cancer.

OBJECTIVES

To assess the effects of mindfulness-based stress reduction (MBSR) in women diagnosed with breast cancer.

SEARCH METHODS

In April 2018, we conducted a comprehensive electronic search for studies of MBSR in women with breast cancer, in the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and two trial registries (World Health Organization's International Clinical Trials Registry Platform (WHO ICTRP) and ClinicalTrials.gov). We also handsearched relevant conference proceedings.

SELECTION CRITERIA

Randomised clinical trials (RCTs) comparing MBSR versus no intervention in women with breast cancer.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. Using a standardised data form, the review authors extracted data in duplicate on methodological quality, participants, interventions and outcomes of interest (quality of life, fatigue, depression, anxiety, quality of sleep, overall survival and adverse events). For outcomes assessed with the same instrument, we used the mean difference (MD) as a summary statistic for meta-analysis; for those assessed with different instruments, we used the standardised mean difference (SMD). The effect of MBSR was assessed in the short term (end of intervention), medium term (up to 6 months after intervention) and long term (up to 24 months after intervention).

MAIN RESULTS

Fourteen RCTs fulfilled our inclusion criteria, with most studies reporting that they included women with early breast cancer. Ten RCTs involving 1571 participants were eligible for meta-analysis, while four studies involving 185 participants did not report usable results. Queries to the authors of these four studies were unsuccessful. All studies were at high risk of performance and detection bias since participants could not be blinded, and only 3 of 14 studies were at low risk of selection bias. Eight of 10 studies included in the meta-analysis recruited participants with early breast cancer (the remaining 2 trials did not restrict inclusion to a certain cancer type). Most trials considered only women who had completed cancer treatment.MBSR may improve quality of life slightly at the end of the intervention (based on low-certainty evidence from three studies with a total of 339 participants) but may result in little to no difference up to 6 months (based on low-certainty evidence from three studies involving 428 participants). Long-term data on quality of life (up to two years after completing MBSR) were available for one study in 97 participants (MD 0.00 on questionnaire FACT-B, 95% CI -5.82 to 5.82; low-certainty evidence).In the short term, MBSR probably reduces fatigue (SMD -0.50, 95% CI -0.86 to -0.14; moderate-certainty evidence; 5 studies; 693 participants). It also probably slightly reduces anxiety (SMD -0.29, 95% CI -0.50 to -0.08; moderate-certainty evidence; 6 studies; 749 participants), and it reduces depression (SMD -0.54, 95% CI -0.86 to -0.22; high-certainty evidence; 6 studies; 745 participants). It probably slightly improves quality of sleep (SMD -0.38, 95% CI -0.79 to 0.04; moderate-certainty evidence; 4 studies; 475 participants). However, these confidence intervals (except for short-term depression) are compatible with both an improvement and little to no difference.In the medium term, MBSR probably results in little to no difference in medium-term fatigue (SMD -0.31, 95% CI -0.84 to 0.23; moderate-certainty evidence; 4 studies; 607 participants). The intervention probably slightly reduces anxiety (SMD -0.28, 95% CI -0.49 to -0.07; moderate-certainty evidence; 7 studies; 1094 participants), depression (SMD -0.32, 95% CI -0.58 to -0.06; moderate-certainty evidence; 7 studies; 1097 participants) and slightly improves quality of sleep (SMD -0.27, 95% CI -0.63 to 0.08; moderate-certainty evidence; 4 studies; 654 participants). However, these confidence intervals are compatible with both an improvement and little to no difference.In the long term, moderate-certainty evidence shows that MBSR probably results in little to no difference in anxiety (SMD -0.09, 95% CI -0.35 to 0.16; 2 studies; 360 participants) or depression (SMD -0.17, 95% CI -0.40 to 0.05; 2 studies; 352 participants). No long-term data were available for fatigue or quality of sleep.No study reported data on survival or adverse events.

AUTHORS' CONCLUSIONS

MBSR may improve quality of life slightly at the end of the intervention but may result in little to no difference later on. MBSR probably slightly reduces anxiety, depression and slightly improves quality of sleep at both the end of the intervention and up to six months later. A beneficial effect on fatigue was apparent at the end of the intervention but not up to six months later. Up to two years after the intervention, MBSR probably results in little to no difference in anxiety and depression; there were no data available for fatigue or quality of sleep.

Effectiveness of therapy group in women with localized breast cancer

Background/Objective

Breast cancer causes high levels of anxiety and depression, deteriorating quality of life of patients. Several studies have found that group therapy reduces depression and anxiety also improves the quality of life. The aim of this study is to analyze group therapy effectiveness in emotional state and quality of life in women with breast cancer after finalized medical treatments.

Method

Participants in this study were 100 adult women diagnosed of breast cancer non-mestastasic and were divided into two types of intervention groups (Self-esteem-Social Skills and Cognitive-Behavioral Therapy). Evaluation instruments were questionnaire Functional Assessment of Breast-cancer Therapy (FACT-B) and Hospital Anxiety and Depression Scale (HADS).

Results

A statistically significant effect of group therapy in reducing anxiety and depression were observed. Quality of life and emotional well-being significantly improved. These effects remain three months after intervention.

Conclusions

The results show that the psychological intervention group is efficient to improve emotional state and quality of life of women with breast cancer.

Therapeutic alliance-not therapist competence or group cohesion-contributes to reduction of psychological distress in group-based mindfulness-based cognitive therapy for cancer patients

Mindfulness‐based cognitive therapy (MBCT) is an innovative evidence‐based intervention in mental and somatic health care. Gaining knowledge of therapeutic factors associated with treatment outcome can improve MBCT. This study focused on predictors of treatment outcome of MBCT for cancer patients and examined whether group cohesion, therapeutic alliance, and therapist competence predicted reduction of psychological distress after MBCT for cancer patients. Moreover, it was examined whether therapist competence facilitated therapeutic alliance or group cohesion. Multilevel analyses were conducted on a subsample of patients collected in a larger randomized controlled trial on individual internet‐based versus group‐based MBCT versus treatment as usual in distressed cancer patients. The current analyses included the 84 patients who completed group‐based MBCT out of 120 patients who were randomized to group‐based MBCT. Group cohesion and therapist competence did not predict reduction in psychological distress, whereas therapeutic alliance did. In addition, therapist competence did not predict therapeutic alliance but was associated with reduced group cohesion. Our findings revealed that therapeutic alliance significantly contributed to reduction of psychological distress in MBCT for cancer patients. Elaborating the clinical implications of the predictive significance of therapeutic alliance might be of added value to enhance the potential effect of MBCT.

Agreement between a single-item measure of anxiety and depression and the Hospital Anxiety and Depression Scale: A cross-sectional study

Anxiety and depression can be heightened among individuals living with chronic diseases. Identifying these individuals is necessary for ensuring they are provided with adequate support. Traditional tools such as clinical interviews or symptom checklists are not always feasible to implement in practice. Robust single-item questions may be a useful alternative. This study aimed to measure agreement, sensitivity, specificity, positive predictive value and negative predictive value of a single-item question about anxiety and depression compared to the widely used Hospital Anxiety and Depression Scale (HADS). A cross-sectional survey of 2,811 people with cancer attending 19 treatment centres in Australia. Patients were approached in the waiting room prior to an outpatient clinic appointment and invited to complete a pen and paper survey. Participants completed the HADS as well as 2 single-items asking if they have felt anxious or depressed in the last week. The single-items for anxiety and depression each demonstrated moderate levels of sensitivity (0.78 for anxiety; 0.63 for depression) and specificity (0.75 for anxiety; 0.84 for depression) against the relevant HADS subscale. Positive predictive values were moderate (0.53 for anxiety and 0.52 for depression) while negative predictive values were high for both single-item questions (0.90 for anxiety and 0.89 for depression). The single-item measures of anxiety and depression may be useful to rule out individuals who do not require further psychological assessment or intervention for anxiety and depression. Further research is needed to explore whether these findings generalise to other chronic diseases.

Putting Integrative Oncology Into Practice: Concepts and Approaches

Unmet symptom needs and a desire for holistic health approaches or even cure are among the motivations patients have for seeking out complementary and alternative medicine. Using complementary and alternative medicine instead of conventional cancer treatment can have a negative impact on clinical outcomes and survival. Integrative oncology is a patient-centered, evidence-informed field of comprehensive cancer care that uses mind-body practices, natural products, and lifestyle modifications from different traditions alongside conventional cancer treatments. It prioritizes safety and best available evidence to offer appropriate therapeutic interventions along with conventional care. This review summarizes the underlying principles of integrative oncology and how it is distinct from alternative medicine, and it provides a practical guide for the effective application of evidence-based complementary and alternative medicine interventions in patient-centered care. In addition, we recommend resources for patients and clinicians and provide algorithms for appropriate integrative medicine referrals. Finally, we offer suggestions on developing and implementing an integrative oncology program and addressing current challenges in the field.

A Large Randomized Trial: Effects of Mindfulness-Based Stress Reduction (MBSR) for Breast Cancer (BC) Survivors on Salivary Cortisol and IL-6

Breast cancer survivors (BCS) often experience psychological and physiological symptoms after cancer treatment. Mindfulness-based stress reduction (MBSR), a complementary and alternative therapy, has reduced subjective measures of stress, anxiety, and fatigue among BCS. Little is known, however, about how MBSR affects objective markers of stress, specifically the stress hormone cortisol and the pro-inflammatory cytokine interleukin-6 (IL-6). In the present study, BCS ( N = 322) were randomly assigned to a 6-week MBSR program for BC or usual-care control. Measurements of cortisol, IL-6, symptoms, and quality of life were obtained at orientation and 6 weeks. Cortisol and IL-6 were also measured prior to and after the MBSR(BC) class Weeks 1 and 6. The mean age of participants was 56.6 years and 69.4% were White non-Hispanic. Most had Stage I (33.8%) or II (35.7%) BC, and 35.7% had received chemotherapy and radiation. Cortisol levels were reduced immediately following MBSR(BC) class compared to before the class Weeks 1 and 6 (Wilcoxon-signed rank test; p < .01, d = .52-.56). IL-6 was significantly reduced from pre- to postclass at Week 6 (Wilcoxon-signed rank test; p < .01, d = .21). No differences were observed between the MBSR(BC) and control groups from baseline to Week 6 using linear mixed models. Significant relationships with small effect sizes were observed between IL-6 and both symptoms and quality of life in both groups. Results support the use of MBSR(BC) to reduce salivary cortisol and IL-6 levels in the short term in BCS.

A Systematic Review: Mindfulness Intervention for Cancer-Related Pain

Moderate-to-severe pain is a common problem experienced by patients with cancer. Although analgesic drugs are effective, adverse side effects are common and some analgesic drugs are addictive. Nonpharmacological treatment may be a way to treat cancer pain without causing negative side effects. Mindfulness is used as an effective nonpharmacological treatment to improve quality of life (QoL) and to address psychological problems including distress, anxiety, stress, and depression. However, the effect of mindfulness on pain severity has not been sufficiently investigated. Therefore, a systematic review was undertaken to describe the effectiveness of mindfulness interventions for pain and its underlying pathophysiologic mechanisms. The search was conducted in PubMed, Ovid MEDLINE, and CINAHL and included only empirical studies published from 2008 to 2017. Search terms included mindfulness, mindfulness-based intervention, meditation, cancer, pain, and cancer-related pain. Six studies met the search criteria. These studies tested several types of intervention including mindfulness-based stress reduction, mindfulness-based cognitive therapy, meditation with massage, and mindful awareness practices. Study outcomes include improved pain severity, anxiety, stress, depression, and QoL. However, most studies reviewed were conducted in the United States and Denmark. Further research is needed to test culturally appropriate mindfulness interventions to reduce pain.

Effectiveness of mindfulness-based stress reduction (MBSR) on symptom variables and health-related quality of life in breast cancer patients-a systematic review and meta-analysis

OBJECTIVE

The purpose of this systematic review and meta-analysis was to evaluate the effectiveness of mindfulness-based stress reduction (MBSR) in breast cancer patients.

METHODS

A systematic search of Cochrane Library, Cochrane Central Register of Controlled Trials, PsycINFO database, Web of science, Medline, EMBASE, CNKI, and CBM database was carried out from February to May 2018, with no language restrictions. Trials examining the effects of MBSR versus control group on symptom variables and health-related quality of life were included. Data concerning studies, patient characteristics, and outcomes were extracted. Methodological quality of each included randomized controlled trials were assessed individually by two reviewers independently using criteria recommended in the Cochrane Handbook for Systematic Reviews of Interventions 5.1.0. Meanwhile, Newcastle-Ottawa Quality Assessment Scale (NOS) was used to evaluate methodological quality of non-randomized studies.

RESULTS

In all, 14 studies involving 1505 participants were included. Due to the effect of MBSR, statistically significant results were found on physiological function (SMD = 0.28, 95% CI [0.07, 0.049], P = 0.008), cognitive function (SMD = 1.48, 95% CI [0.34, 2.61], P = 0.01), fatigue (SMD = - 0.66, 95% CI [- 1.11, - 0.20], P = 0.004), emotional wellbeing (SMD = 1.01, 95% CI [0.35, 1.67], P = 0.003), anxiety (SMD = - 0.54, 95% CI [- 1.01, - 0.07], P = 0.02), depression (SMD = - 0.61, 95% CI [- 1.11, - 0.11], P = 0.02), stress (SMD = - 0.48, 95% CI [- 0.81, - 0.15], P = 0.004), distress (SMD = - 0.56, 95% CI [- 0.85, - 0.26], P = 0.0002) and mindfulness (SMD = 0.94, 95% CI [0.10, 1.79], P = 0.03). Although the effects on pain, sleep quality, and global QoL were in the expected direction, they were not statistically significant (P > 0.05) based on insufficient evidence.

CONCLUSIONS

MBSR is worthy of being recommended to breast cancer patients as a complementary treatment or adjunctive therapy.

Smartphone problem-solving and behavioural activation therapy to reduce fear of recurrence among patients with breast cancer (SMartphone Intervention to LEssen fear of cancer recurrence: SMILE project): protocol for a randomised controlled trial

INTRODUCTION

One of the most common distressing conditions experienced by breast cancer survivors is fear of cancer recurrence (FCR). There is, however, no standard intervention for ameliorating FCR. Our clinical experience and previous studies have suggested the potential benefits of problem-solving therapy (PST) and behavioural activation (BA). Given the huge number of cancer survivors and limited number of therapists to competently conduct PST and BA, we have developed PST and BA smartphone applications. This study aimed to evaluate the efficacy of the smartphone-based PST (Kaiketsu-App) and BA (Genki-App) apps in reducing FCR in patients with breast cancer.

METHODS AND ANALYSIS

The SMartphone Intervention to LEssen fear of cancer recurrence project is an open-label, individually randomised, parallel-group trial. Allocation will be managed by a central server using a computer-generated random allocation sequence provided by an independent data centre. Participants will be randomised to smartphone-based intervention plus treatment as usual (TAU) or waitlist control with TAU alone. The primary endpoint of the study is the Japanese version of the Concerns About Recurrence Scale, which will be administered as an electronic patient-reported outcome on the patients' smartphone after 8 weeks.

ETHICS AND DISSEMINATION

The present study is subject to the ethical guidelines for clinical studies published by Japan's Ministry of Education, Science and Technology and Ministry of Health, Labour and Welfare and the modified Act on the Protection of Personal Information as well as the ethical principles established for research on humans stipulated in the Declaration of Helsinki and further amendments thereto. The protocol was approved by the Institutional Review Board of Nagoya City University on 15 January 2018 (ID: 60-00-1171).

TRIAL STATUS

The randomised trial, which commenced on 2 April 2018, currently enrols participants. The estimated end date for this study is in March 2020.

Mind-body interventions for fear of cancer recurrence: A systematic review and meta-analysis

OBJECTIVE

Fear of cancer recurrence (FCR) is a common existential concern and source of distress among adults with a cancer history. Multiple randomized controlled trials (RCTs) have examined mind-body approaches to mitigating FCR. We summarized characteristics of these trials and calculated their pooled effects on decreasing FCR.

METHODS

Six electronic databases were systematically searched from inception to May 2017, using a strategy that included multiple terms for RCTs, cancer, mind-body medicine, and FCR. Data extraction and reporting followed Cochrane and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Pooled effect sizes on self-report measures of FCR were computed by using random-effects models.

RESULTS

Nineteen RCTs (pooled N = 2806) were included. Most studies (53%) were published since 2015 and targeted a single cancer type (84%; mostly breast). Intervention sessions (median = 6, mode = 4) tended to last 120 minutes and occur across 1.5 months. Delivery was predominantly in-person (63%) to either groups (42%) or individuals (42%). Most interventions incorporated multiple mind-body components (53%), commonly cognitive-behavioral skills (58%), or meditative practices (53%). Small-to-medium pooled effect sizes were observed postintervention (Hedges' g = -0.36, 95% CI = -0.49, -0.23, P < .001) and at follow-up assessments (median = 8 months, P < .001). Potential modifiers (control group design, group/individual delivery, use of cognitive-behavioral or mindfulness skills, number of mind-body components, cancer treatment status, and number of sessions) did not reach statistical significance.

CONCLUSIONS

Mind-body interventions are efficacious for reducing FCR, with small-to-medium effect sizes that persist after intervention delivery ends. Recommendations include testing effects among survivors of various cancers and exploring the optimal integration of mind-body practices for managing fundamental uncertainties and fears during cancer survivorship.

Consolidation and prediction of long-term treatment effect of group and online mindfulness-based cognitive therapy for distressed cancer patients

BACKGROUND

Group face-to-face and individual internet-based mindfulness-based cognitive therapy (MBCT and eMBCT) have been demonstrated to reduce psychological distress for distressed cancer patients in a randomized controlled trial (RCT). This study focused on the long-term effects of this RCT during the nine-month follow-up period, and on possible predictors, moderators and working mechanisms.

METHODS

Distressed cancer patients (n = 245) were randomized to MBCT or eMBCT. Data were collected at baseline, post-treatment, three- and nine-month follow-up. Data were analyzed with linear mixed effect models and (hierarchical) linear regressions.

RESULTS

Analyses revealed long-term reductions in psychological distress and rumination, and long-term increases in positive mental health and mental health-related quality of life (QoL) in both interventions over the course of the nine-month follow-up. Interestingly, patients reported less psychological distress in the follow-up period after eMBCT in comparison to MBCT. Less psychological distress, rumination and neuroticism, and more extraversion and agreeableness at baseline predicted less psychological distress at the nine-month follow-up after both interventions. Less mindful and conscientious patients at baseline benefited more from eMBCT than from MBCT. Regarding working mechanisms, changes in mindfulness skills, fear of cancer recurrence and rumination during both interventions predicted less psychological distress at follow-up.

CONCLUSIONS

Our findings suggest most improvements in cancer patients' increase over time after both interventions. Furthermore, patients seemed to benefit more from eMBCT than MBCT based on psychological distress levels, especially those patients with low levels of mindfulness skills and conscientiousness.

Face-to-Face and Internet-Based Mindfulness-Based Cognitive Therapy Compared With Treatment as Usual in Reducing Psychological Distress in Patients With Cancer: A Multicenter Randomized Controlled Trial

Purpose Mindfulness-based cognitive therapy (MBCT) has been shown to alleviate psychological distress in patients with cancer. However, patients experience barriers to participating in face-to-face MBCT. Individual Internet-based MBCT (eMBCT) could be an alternative. The study aim was to compare MBCT and eMBCT with treatment as usual (TAU) for psychological distress in patients with cancer. Patients and Methods We obtained ethical and safety approval to include 245 patients with cancer with psychological distress (≥ 11 on the Hospital Anxiety and Depression Scale) in the study. They were randomly allocated to MBCT (n = 77), eMBCT (n = 90), or TAU (n = 78). Patients completed baseline (T0) and postintervention (T1) assessments. The primary outcome was psychological distress on the Hospital Anxiety and Depression Scale. Secondary outcomes were psychiatric diagnosis, fear of cancer recurrence, rumination, health-related quality of life, mindfulness skills, and positive mental health. Continuous outcomes were analyzed using linear mixed modeling on the intention-to-treat sample. Because both interventions were compared with TAU, the type I error rate was set at P < .025. Results Compared with TAU, patients reported significantly less psychological distress after both MBCT (Cohen's d, .45; P < .001) and eMBCT (Cohen's d, .71; P < .001) . In addition, post-treatment prevalence of psychiatric diagnosis was lower with both MBCT (33% improvement; P = .030) and eMBCT (29% improvement; P = .076) in comparison with TAU (16%), but these changes were not statistically significant. Both interventions reduced fear of cancer recurrence and rumination, and increased mental health-related quality of life, mindfulness skills, and positive mental health compared with TAU (all Ps < .025). Physical health-related quality of life did not improve ( P = .343). Conclusion Compared with TAU, MBCT and eMBCT were similarly effective in reducing psychological distress in a sample of distressed heterogeneous patients with cancer.

Being Present: A single-arm feasibility study of audio-based mindfulness meditation for colorectal cancer patients and caregivers

A metastatic cancer diagnosis is associated with high levels of distress in patients and caregivers. Mindfulness interventions can reduce distress and improve quality of life in cancer patients. However, standard mindfulness training relies on in-person instruction, which is often not practical for either patients receiving chemotherapy or their caregivers. In the Being Present single arm pilot study, we designed and tested an 8-week audio-based mindfulness meditation program for patients with metastatic colorectal cancer receiving chemotherapy with or without a participating caregiver. The study accrued 33 of 74 (45%) eligible patients consenting together with 20 family caregivers (53 participants total) within nine months. Forty-one participants were evaluable (77%); 10 of 12 cases of attrition were attributable to hospitalization or death. Median participant age was 51 (range 21-78 years); 38% were men. Baseline levels of distress were similar in patients and caregivers. The top reasons for participation cited in pre-intervention interviews were to increase relaxation/calm, improve mood/emotions, and reduce stress/anxiety. In measures of adherence, 59% of responses to weekly texts asking: "Have you practiced today?" were "Yes" and 59% of interviewees reported practicing >50% of the time. Compared to baseline, post-intervention surveys demonstrated significantly reduced distress (p = 0.01) and anxiety (p = 0.03); as well as increased non-reactivity (p<0.01), and feeling at peace (p<0.01). Post-intervention qualitative interviews, where 71% of participants reported benefit, were consistent with quantitative findings. In the interviews, participants spontaneously described reduced stress/anxiety and increased relaxation/calm. Benefits appeared to be accentuated in patient-caregiver pairs as compared to unpaired patients. Seventy-nine percent of participants reported plans for continued practice after study completion. We conclude that the Being Present audio-based mindfulness meditation program is of interest to, feasible, and acceptable for patients with metastatic colorectal cancer and caregivers, with initial evidence of efficacy. These results will guide plans for a follow-up study.

Associations Between Perceived Stress and Chemotherapy-Induced Peripheral Neuropathy and Otoxicity in Adult Cancer Survivors

CONTEXT

The most common adverse effects from neurotoxic chemotherapy are chemotherapy-induced neuropathy (CIPN), hearing loss, and tinnitus. Although associations between perceived stress and persistent pain, hearing loss, and tinnitus are documented, no studies have examined these associations in cancer survivors who received neurotoxic chemotherapy.

OBJECTIVES

In this cross-sectional study, we evaluated for associations between perceived stress and the occurrence of CIPN, hearing loss, and tinnitus, in 623 adult cancer survivors who received platinum and/or taxane compounds.

METHODS

Survivors completed self-report measures of hearing loss, tinnitus, and perceived stress (i.e., Impact of Events Scale-Revised [IES-R]). Separate logistic regression analyses were done for each neurotoxicity to evaluate whether each of the IES-R subscale (i.e., intrusion, avoidance, hyperarousal) and total scores made a significant independent contribution to neurotoxicity group membership.

RESULTS

Of the 623 survivors in this study, 68.4% had CIPN, 34.5% reported hearing loss, and 31.0% reported tinnitus. Older age, higher body mass index, poorer functional status, being born prematurely, cancer diagnosis, and higher intrusion (P = 0.013), hyperarousal (P = 0.014), and total (P = 0.047) IES-R scores were associated with CIPN. Older age, being male, poorer functional status, a worse comorbidity profile, and a higher IES-R hyperarousal (P = 0.007) score were associated with hearing loss. Being male, having less education, a worse comorbidity profile, and a higher IES-R hyperarousal (P = 0.029) score were associated with tinnitus.

CONCLUSION

These findings suggest that increased levels of perceived stress are associated with the most common chemotherapy-induced neurotoxicities.

Resilience Among Breast Cancer Survivors of Different Sexual Orientations

PURPOSE

Resilience could help protect the psychosocial wellbeing of sexual minority women (SMW) experiencing stressors from both breast cancer and sexual minority status; however, little research has assessed resilience among breast cancer survivors of different sexual orientations.

METHODS

From 2011 to 2012, we surveyed a national sample of breast cancer survivors matched on sexual orientation, age, and cancer status.

RESULTS

Among heterosexual (n = 339) and sexual minority (n = 201) breast cancer survivors (n = 540 overall), multivariable regression analyses revealed that more social support (coefficient: 0.87; 95% confidence interval [CI]: 0.56-1.19), fighting spirit combined with helplessness/hopelessness (coefficient: 0.30; 95% CI: 0.13-0.47), and fatalism (coefficient: 0.40; 95% CI: 0.14-0.65) were associated with greater resilience. Mental health counseling before breast cancer diagnosis and anxious preoccupation following cancer diagnosis were associated with reduced resilience (coefficient: -2.50; 95% CI: -3.83 to -1.18; and -0.46; 95% CI: -0.60 to -0.32). Although sexual orientation was not independently associated with resilience, among SMW, those who were unemployed had reduced resilience compared with those who were employed (coefficient: -3.52; 95% CI: -5.75 to -1.28), whereas there was no association between employment and resilience among heterosexual women.

CONCLUSION

These findings suggest that social support and other factors associated with resilience could be leveraged by interventions to improve the health and wellbeing of diverse cancer survivors.

Quality of life among women diagnosed with breast Cancer: A randomized waitlist controlled trial of commercially available mobile app-delivered mindfulness training

OBJECTIVE

The primary objective was to evaluate the efficacy of commercially available mobile app-delivered mindfulness training (AMT), compared with waitlist control (WC), on quality of life (QOL) among women diagnosed with breast cancer. The secondary outcome was dispositional mindfulness. Enrollment, app utilization, and study completion are reported as feasibility objectives.

METHODS

Women diagnosed with breast cancer ≤5 years (n = 112) were randomized to AMT (n = 57) or WC (n = 55), over 8 weeks, with 4 weeks of follow-up. We conducted linear mixed effects models to examine group by observation interactions on QOL and dispositional mindfulness at baseline, during intervention (5-weeks), post-intervention (9-weeks), and follow-up (12-weeks post-baseline).

RESULTS

Participants assigned to AMT reported higher QOL, compared with those assigned to WC, from baseline through follow-up t(258.40) = 3.09, P < 0.01, 95% CI [2.71, 11.90]. Participants assigned to AMT also reported higher dispositional mindfulness, compared with those assigned to WC, from baseline through follow-up t(268.44) = 2.04, P = 0.04, 95% CI [0.01, 0.57]. App utilization data was obtained from 34 participants. Fewer participants assigned to AMT completed all study assessments, compared with participants assigned to WC, (χ2¹  = 7.07, P = 0.008).

CONCLUSIONS

Findings suggest commercially available AMT may proffer some benefit to women seeking to enhance their QOL following breast cancer diagnosis.

Care After Chemotherapy: Peripheral Neuropathy, Cannabis for Symptom Control, and Mindfulness

As cancer therapies improve, patients are living longer. With these improvements in therapy comes a responsibility to optimize patients' quality of life during cancer therapy and beyond. This report reviews three timely and important topics. The first section reviews the mechanism underlying chemotherapy-induced peripheral neuropathy and evaluates the evidence for interventions to prevent and treat peripheral neuropathy. It also provides a framework for approaching the diagnosis and management of this common and bothersome side effect. The second section addresses the controversial but effective use of cannabinoids for cancer and chemotherapy symptoms. Although clinical trials are difficult to conduct because of the political and social stigma of this class of drugs, this review provides evidence of the efficacy of cannabinoids for treatment of pain and nausea. The last section addresses the mind-body connection, with a focus on the negative emotions patients with cancer often experience. This section assesses the literature regarding mindfulness-based programs to improve cancer-related stress. These three topics may appear unrelated, but all address one common goal: treating the body and the mind to optimize quality of life during and after cancer therapy.

Psychosocial distress and the preferred method of delivery of mind-body interventions among patients with head-and-neck cancer

Objective

To describe the psychosocial distress of head-and-neck cancer patients at the completion of therapy and the interest in and the preferred method of delivery of mind-body interventions (MBIs) among head-and-neck cancer patients.

Materials and methods

A descriptive, cross-sectional design was used to measure sleep disturbance, depression, anxiety, and the interest in and the preference for MBIs using anonymous, self-report questionnaires among a convenience sample of 30 males at their 3-month follow-up. Questionnaires included the Pittsburgh Sleep Quality Index, Hospital Anxiety and Depression Scale, and the self-created Survey for Preferred Methods of MBI. Frequency distributions and descriptive statistics were used to describe the sample demographic and clinical characteristics.

Results

The mean age of the sample was 59 years. Oral cancer (63%) was the most common type of cancer. Nineteen participants (63%, 90% CI 47%-78%) had some interest in MBIs. Of interested participants, 8 (42%) preferred participating in MBIs alone, 10 (53%) preferred participating in MBIs at homes, 10 (53%) preferred participating in MBIs using a computer or mobile device, and 8 (42%) preferred participating in MBIs after the diagnosis, but before treatment started. Mean depression, anxiety, and sleep disturbance scores were 8.25 (SD 2.93), 5.41 (SD 3.52), and 6.3 (SD 3.86), respectively. Results from the independent-samples t-test and Mann-Whitney U tests revealed no significant differences in anxiety, depression, and sleep disturbance by MBI interest.

Conclusion

Asking about depression, anxiety, and sleep disturbances may help to identify head-and-neck cancer patients at risk for psychosocial distress. These findings suggest an interest in MBIs, but further research is warranted.

Feasibility of an online mindfulness-based program for patients with melanoma: study protocol for a randomised controlled trial

BACKGROUND

People with a melanoma diagnosis are at risk of recurrence, developing a new primary or experiencing disease progression. Previous studies have suggested that fear of a cancer recurrence is clinically relevant in this group of patients and, if not addressed, can lead to distress. Mindfulness-based interventions have been shown to alleviate symptoms of anxiety and depression among various groups of cancer patients. Online mindfulness-based interventions have the potential to reach people unable to attend face-to-face interventions due to limitations such as cancer-related illness, transportation or time constraints. This study aims to (1) examine whether individuals with a melanoma diagnosis are willing to participate and adhere to a 6-week online mindfulness-based intervention and (2) explore potential benefits of the program on fear of cancer recurrence, worries, rumination, perceived stress and trait mindfulness to inform the design of a clinical trial.

METHODS/DESIGN

This is a single-site randomised controlled trial of a feasibility study. Seventy-five participants with stage 2c or 3 melanoma will be recruited from a melanoma outpatient clinic and randomised (2:1) either to an online mindfulness-based program (intervention) or to usual care (control). The intervention is a 6-week program specifically developed for this study. It consists of videos describing the concept of mindfulness, short daily guided meditation practices (5-10 min), automated meditation reminders and instructions for applying mindfulness in daily life to enhance wellbeing. All participants will complete questionnaires at baseline and at 6-week post-randomisation. Participants in the control group will be given access to the online program at the end of the study. Primary outcomes are overall recruitment; retention; extent of questionnaire completion; and usability and acceptability of, and adherence to, the program. The secondary outcomes are fear of cancer recurrence, worries, rumination, perceived stress and trait mindfulness measured using validated instruments.

DISCUSSION

This feasibility study will evaluate participants' satisfaction with the program and identify barriers to recruitment and adherence. The recruitment and data collection process will highlight methodological aspects to address in the planning of a larger scale study assessing the impact of an online mindfulness-based intervention on fear of cancer recurrence and wellbeing.
