Study protocol of a randomized controlled trial comparing Mindfulness-Based Stress Reduction with treatment as usual in reducing psychological distress in patients with lung cancer and their partners: the MILON study

Mindfulness-Based Interventions for Survivors of Lung Cancer and Their Partners: A Systematic Review

BACKGROUND

Survivors of lung cancer and their partners often have complex unresolved physical, psychosocial, and behavioral needs that can negatively affect the survivors' and partners' well-being. This systematic review aimed to (1) examine the content and delivery of mindfulness-based interventions (MBIs) and (2) summarize and synthesize the current evidence for effectiveness of MBIs targeting survivors of lung cancer and/or one selected partner (dyads).

METHOD

Six databases were searched for interventional studies published in English between 1980 and June 2020 using three terms (lung neoplasms, mindfulness, caregivers). For outcome measures, the interventions focused on behavioral change (meditation, yoga, stretching, breathing), symptom management (dyspnea, fatigue, sleep disruption, anxiety, depression, stress reduction), and knowledge. Two reviewers independently assessed article eligibility. One reviewer performed and another independently verified data extraction. The Cochrane risk-of-bias tool for randomized trials was used to critically appraise RCTs.

RESULTS

Searching yielded 307 records, of which 64 were assessed for eligibility. Six studies investigated the impact of an MBI on survivors and partners. Four studies were single-arm feasibility studies; two were RCTs. Two feasibility studies and one RCT recruited romantic couples whereas the others recruited asymmetrical dyads. The single-arm studies reported strong feasibility and acceptability. RCTs reported significant outcomes for reduced cancer-related distress and depression, and improved QOL, self-compassion, mindfulness skills, and rumination.

CONCLUSION

Dyadic intervention research is a growing field. Few interventions target individuals with lung cancer and their partners. No interventions target partners alone. Future research should evaluate rigorous methodologies that enhance the understanding of independent and interdependent health-related effects within dyads and across relationships and settings.

Symptom Assessment Following Surgery for Lung Cancer: A Canadian Population-based Retrospective Cohort Study

OBJECTIVE

To conduct a population-level analysis of temporal trends and risk factors for high symptom burden in patients receiving surgery for non-small cell lung cancer (NSCLC).

BACKGROUND

A population-level overview of symptoms after curative intent surgery is necessary to inform decision making and supportive care for patients with lung cancer.

METHODS

Retrospective cohort study of patients receiving surgery for stages I to III NSCLC between January 2007 and September 2018. Prospectively collection Edmonton Symptom Assessment System (ESAS) scores, linked to provincial administrative data, were used to describe the prevalence, trajectory, and predictors of moderate-to-severe symptoms in the year following surgery.

RESULTS

A total of 5350 patients, with 28,490 unique ESAS assessments, were included in the analysis. Moderate-to-severe tiredness (68%), poor wellbeing (63%), and shortness of breath (60%) were the most common symptoms reported. The rise and fall in the proportion of patients experiencing moderate-to-severe symptoms after surgery coincided with the median time to first (58 days, interquartile range: 47-72) and last cycle of chemotherapy (140 days, interquartile range: 118-168), respectively. There was eventual stabilization, albeit above the preoperative baseline, within 6 to 7 months after surgery. Female sex (relative risk [RR] 1.09- 1.26), lower income (RR 1.08-1.23), stage III disease (RR 1.15-1.43), adjuvant therapy (RR 1.09-1.42), chemotherapy within 2 weeks of an ESAS assessment (RR 1.14-1.73), and pneumonectomy (RR 1.05-1.15) were associated with moderate-to-severe symptoms following surgery.

CONCLUSIONS

Knowledge of population-level prevalence, trajectory, and predictors of moderate-to-severe symptoms after surgery for NSCLC can be used to facilitate shared decision making and improve symptom management throughout the course of illness.

Psychological intervention to treat distress: An emerging frontier in cancer prevention and therapy

Psychological distress, such as chronic depression and anxiety, is a topical problem. In the context of cancer patients, prevalence rates of psychological distress are four-times higher than in the general population and often confer worse outcomes. In addition to evidence from epidemiological studies confirming the links between psychological distress and cancer progression, a growing body of cellular and molecular studies have also revealed the complex signaling networks which are modulated by psychological distress-derived chronic stress during cancer progression. In this review, aiming to uncover the intertwined networks of chronic stress-driven oncogenesis and progression, we summarize physiological stress response pathways, like the HPA, SNS, and MGB axes, that modulate the release of stress hormones with potential carcinogenic properties. Furthermore, we discuss in detail the mechanisms behind these chronic stimulations contributing to the initiation and progression of cancer through direct regulation of cancer hallmarks-related signaling or indirect promotion of cancer risk factors (including obesity, disordered circadian rhythms, and premature senescence), suggesting a novel research direction into cancer prevention and therapy on the basis of psychological interventions.

Influence of Psychological Nursing Intervention on Psychological State, Treatment Compliance, and Immune Function of Postoperative Patients with Rectal Cancer

In order to explore the clinical effect of psychological nursing intervention on postoperative chemotherapy for rectal cancer, 120 cases of rectal cancer patients were selected as the research subjects. The control group received conventional nursing treatment after operation, and the research group received comprehensive psychological nursing intervention on this basis. The self-rating anxiety scale (SAS) scores, self-rating depression scale (SDS) scores, hope level scores, nursing satisfaction, mental state changes, treatment compliance, and immune function of two groups were analyzed and compared. There was no significant difference between the two groups of patients in the preoperative SAS, SDS, and hope level scale scores. After the intervention, postoperative SAS and SDS scores and CD8⁺ value of the research group were significantly lower than those of the control group. In contrast, the postoperative hope level score, treatment compliance, and postoperative CD4⁺/CD8⁺ of the research group were significantly higher, and the nursing satisfaction was better than that of the control group. The application of psychological nursing intervention in postoperative chemotherapy for patients with rectal cancer can effectively relieve anxiety and depression of patients, promote patients to establish a healthy and coordinated mental state, improve treatment compliance, improve immune function, and promote disease recovery.

Efficacy of Mindfulness-Based Cognitive Therapy and Cognitive Behavioral Therapy for Anxiety, Depression, and Fatigue in Cancer Patients: A Randomized Clinical Trial

Objective: Cancer is associated with some psychological problems that play an important role in the severity and continuity of cancer. Cancer may lead to maladaptive psychological reactions such as anxiety, depression, and fatigue. Depression and anxiety are highly prevalent in cancer patients. This study aimed to compare the efficacy of mindfulness-based cognitive therapy (MBCT) and cognitive behavioral therapy (CBT) for anxiety, depression, and fatigue in cancer patients.

Method: The present study was a randomized clinical trial (RCT). Of the 100 patients diagnosed with cancer, 60 patients were eligible to participate in this study according to the inclusion / exclusion criteria. They were randomly assigned into 3 groups: MBCT, CBT, and wait-list group (WLG). Afterward, the experimental groups received 8 weekly treatment sessions. All the participants fulfilled the Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), and Cancer-Related Fatigue Scale (CFS) before and after the intervention. Data were analyzed using SPSS-16 software by Analysis of Covariance (ANCOVA).

Results: The results indicated a significant reduction in depression, anxiety, and fatigue scores in CBT and MBCT groups. There was a significant difference between both treatment groups with WLG in the anxiety and depression, but no significant difference was found between MBCT and CBT groups. Additionally, there was only a significant difference between the CBT group and WLG in terms of fatigue (P = 0.01).

Conclusion: CBT and MBCT performed equally well in decreasing anxiety and depression in cancer patients, and they were significantly better than WLG. It seems that MBCT is a good alternative to CBT for decreasing emotional symptoms in cancer patients. As a result, CBT and MBCT could be considered a good addition to pharmacological treatment of cancer patients with comorbid psychological symptoms. However, CBT was preferable to MBCT in decreasing fatigue.

The study was registered at the irct.ir database under registration number IRCT20180503039509N1.

Severe symptoms persist for Up to one year after diagnosis of stage I-III lung cancer: An analysis of province-wide patient reported outcomes

OBJECTIVES

Lung cancer is associated with significant disease- and treatment-related morbidity. The Edmonton Symptom Assessment System (ESAS) is a tool developed to elicit patients' own assessment of the severity of common cancer-associated symptoms. The objective of this study was to examine symptom severity in the 12 months following diagnosis of lung cancer, and to identify predictors of high symptom burden.

MATERIALS AND METHODS

This was a retrospective population-based cohort study, including patients with stage I-III lung cancer diagnosed between 2007-2016, and who had symptom screening in the 12 months following diagnosis. The proportion of patients reporting severe symptoms (ESAS ≥ 7) in the year following diagnosis was plotted over time. Multivariable regression models were constructed to identify factors associated with severe symptoms.

RESULTS

69,440 unique symptom assessments were reported by 11,075 lung cancer patients. Tiredness was the most prevalent severe symptom (47.3 %), followed by shortness of breath (39.4 %) and poor wellbeing (36.5 %) among all disease stages. Patients diagnosed with higher stage disease reported more severe symptoms, but symptom trajectories were similar for all stages in the year following diagnosis. Disease stage (RR 1.10-2.01), comorbidity burden (RR 1.17-1.51), degree of socioeconomic marginalization (RR1.15-1.45), and female sex (RR 1.15-1.50) were associated with reporting severe symptoms in the year following diagnosis.

CONCLUSION

Severe physical and psychological symptoms persist throughout the first year following lung cancer diagnosis, regardless of disease stage. Those at risk of experiencing high symptom burden may benefit from targeted supportive care interventions, including psychosocial support aimed at improving health-related quality of life.

A Randomized Controlled Trial of mHealth Mindfulness Intervention for Cancer Patients and Informal Cancer Caregivers: A Feasibility Study Within an Integrated Health Care Delivery System

Purpose: To assess feasibility and preliminary efficacy of a mobile/online-based (mHealth) mindfulness intervention for cancer patients and their caregivers to reduce distress and improve quality of life (QoL). Material and Methods: Two-arm randomized controlled trial within Kaiser Permanente Northern California targeting cancer patients who received chemotherapy and their informal caregivers. The intervention group received a commercially available mindfulness program for 8 weeks. The wait-list control group received usual care. We assessed feasibility using retention and adherence rates and obtained participant-reported data on distress, QoL, sleep, mindfulness, and posttraumatic growth before and immediately after the intervention. Results: Ninety-seven patients (median age 59 years; female 69%; 65% whites) and 31 caregivers (median age 63 years; female 58%; 77% whites) were randomized. Among randomized participants, 74% of the patients and 84% of the caregivers completed the study. Among those in the intervention arm who initiated the mindfulness program, 65% practiced at least 50% of the days during the intervention period. We observed significantly greater improvement in QoL among patients in the intervention arm compared with controls. Caregivers in the intervention group experienced increased mindfulness compared with controls. Participants appreciated the convenience of the intervention and the mindfulness skills they obtained from the program. Conclusion: We demonstrated the feasibility of conducting a randomized trial of an mHealth mindfulness intervention for cancer patients and their informal caregivers. Results from fully powered efficacy trials would inform the potential for clinicians to use this scalable intervention to help improve QoL of those affected by cancer and their caregivers.

Study protocol of a randomized controlled trial comparing integrative body-mind-spirit intervention and cognitive behavioral therapy in fostering quality of life of patients with lung cancer and their family caregivers

Compared to cancers at other sites, lung cancer often results in greater psychosocial distress to both the patients and their caregivers, due to the poor prognosis and survival rate, as well as the heavy symptom burden. In recent years, making protocols of proposed or on-going studies publicly available via clinical trial registries and/or peer-reviewed journals has benefited health sciences with timely communication of the latest research trends and improved transparency in reporting. However, such practice is yet to be a common sight in evidence-informed social work. Hence, this paper discusses the value of publishing protocols in social work research and presents the protocol of a randomized controlled trial that compares the effectiveness of integrative body-mind-spirit intervention with cognitive behavioral therapy for enhancing quality of life of patients with lung cancer and their family caregivers. The data collection process was still on-going at the time of manuscript submission.

Psychosocial challenges for patients with advanced lung cancer: interventions to improve well-being

As compared to other cancers, lung malignancies are associated with high symptom burden, poorer prognosis, and stigmatization. Such factors increase psychological distress and negatively impact quality of life. Research has documented the efficacy of psychosocial interventions to alleviate psychological distress and promote well-being among patients with cancer. This article summarizes the current literature on psychosocial interventions in lung cancer. Major types of psychosocial interventions in lung cancer include cognitive-behavioral therapies, psycho-education, mind-body, exercise, and supportive or palliative care strategies. Discussion relative to the purpose, sample, research design, outcomes, and quality of the studies is presented. Findings may be useful in clinical environments as a resource to help health providers better understand mental health treatment options and care for patients facing lung cancer. The need to direct future research toward the advancement of science and improve well-being and quality of life outcomes for patients with advanced lung cancer and their family members is discussed.

The Effect of a Communicational Program on Psychological Distress in the Elderly Suffering from Cancer

BACKGROUND

Psychological distress is one of the most common psychological symptoms in elderly cancer patients. However, many of these patients do not receive any treatment for distress management. Therefore, we aimed to assess the effect of a communication program on the psychological distress of elderly cancer patients.

MATERIALS AND METHODS

This two-group clinical trial with a before and after design was conducted in Al-Zahra and Seyed-Al-Shohada hospitals affiliated to the Isfahan University of Medical Sciences in 2015. A total of 64 elderly patients were randomly assigned to two groups: experimental and control groups. A 3-week intervention (communicational program) consisting of distributing educational booklets, practices, and phone follow-ups was performed for the intervention group. All sessions were held during the 3-week period with sessions held twice per week both in the form of personal attendance and phone tracking, and the patients were encouraged to do the tasks assigned to them. The control group received routine care, and at the end of the study, the content of the sessions was explained to them. The demographic and clinical data of the participants were recorded, and all participants completed Kessler's Psychological Distress inventory at baseline and at the end of the 3-week intervention.

RESULTS

We found a significant difference in the psychological distress scores between the two groups before and after the intervention (P < 0.001, independent t-test). Moreover, the mean psychological distress scores decreased significantly in the experimental group after the intervention (P < 0.001, paired t-test).

CONCLUSIONS

Our communicational program had a positive effect on psychological distress in elderly patients with cancer. Therefore, this program could be used as an easy, cheap, and practical approach for reducing psychological distress in these patients.

Mindfulness-based stress reduction for breast cancer patients: a mixed method study on what patients experience as a suitable stage to participate

Purpose

Breast cancer is associated with high levels of psychological distress. Mindfulness-based stress reduction (MBSR) has proven to be effective in reducing distress in cancer patients. In several studies, patients who are currently undergoing somatic anticancer treatment are excluded from participating in MBSR. Little is known about what would be the most suitable stage of disease to offer MBSR. We examined whether stage of disease facilitated and/or hindered participation in MBSR for breast cancer patients.

Method

A mixed method design was used. Self-report questionnaires on psychological distress (HADS) and quality of life (EORTC QLQ-C30) were administered before and after MBSR. Five focus groups and three semi-structured individual interviews were conducted. Qualitative data were analyzed with the constant comparative method in order to develop a grounded theory.

Results

Sixty-four females participated in MBSR. In 52 patients who completed the questionnaires, psychological distress improved significantly. Qualitative data showed that participating in MBSR both during and after anticancer treatment has specific advantages and disadvantages. Interestingly, being emotionally ready to take part in MBSR seems equally important as physical ability. Informing patients at an early stage seemed to strengthen autonomy and self-management skills.

Conclusions

In contrast to the common practice to tailoring the timing of MBSR to physical impairments or demands of the anticancer treatment, our findings revealed that emotional readiness is equally important to take into account. These findings might support professionals in their choices whether and when to inform and refer patients to MBSR.

Are Mindfulness and Self-Compassion Related to Psychological Distress and Communication in Couples Facing Lung Cancer? A Dyadic Approach

Lung cancer patients and their spouses report high rates of distress. Due to the increasing popularity of and evidence for mindfulness-based interventions in cancer, mindfulness and self-compassion have been identified as potentially helpful skills when coping with cancer. This dyadic study examined how mindfulness and self-compassion are related to psychological distress and communication about cancer in couples facing lung cancer. Using the actor-partner interdependence model, self-reported mindfulness, self-compassion, psychological distress and communication about cancer were analyzed in a cross-sectional sample of 88 couples facing lung cancer. Regarding psychological distress, no difference was found between patients and spouses. In both partners, own levels of mindfulness (B = −0.19, p = .002) and self-compassion (B = −0.45, p < .001) were negatively related to own distress levels. At a dyadic level, own self-compassion was less strongly associated with distress if the partner reported high self-compassion (B = 0.03, p = .049). Regarding communication about cancer, patients reported to communicate more openly with their partner than with spouses. However, after controlling for gender, this difference was no longer significant. In both partners, own self-compassion (B = 0.03, p = .010) was significantly associated with own communication while mindfulness was not. A trend showed that mindfulness of the partner was related to more open communication in the individual (B = 0.01, p = .080). These findings give a first indication that mindfulness and self-compassion skills may go beyond the individual and could impact couple functioning. Future research should examine whether couples facing (lung) cancer may benefit from programs in which mindfulness and self-compassion are cultivated.

Fatigue in lung cancer patients: symptom burden and management of challenges

Lung cancer (LC) remains the most common cause of cancer death in several countries across the world. Fatigue is the most frequently reported symptom in LC patients throughout the entire course of disease, and all international guidelines recommend early screening for cancer-related fatigue (CRF) and symptoms that can affect patients' quality of life. In patients with LC, fatigue belongs to the symptom cluster of pain, depression, and insomnia, which are commonly observed simultaneously, but are typically treated as separate although they may have common biological mechanisms. The treatment of CRF remains one of the difficult areas in the oncology field: scarce evidence supports pharmacological therapies, while some interesting data arising indicates alternative remedies and physical exercise seem to be one of the most effective approaches for CRF at any stage of LC.

A qualitative study on mindfulness-based stress reduction for breast cancer patients: how women experience participating with fellow patients

Purpose

Peer support groups for cancer patients show mixed findings regarding effectiveness on psychological wellbeing. When embedded in a psychosocial intervention, such as mindfulness-based stress reduction (MBSR), peer support might be of more benefit to participants. This study is a qualitative exploration of how women with breast cancer experience the possible benefits and impediments of participating with fellow patients in an MBSR training.

Methods

Five focus groups (n = 37) and three individual interviews (n = 3) were conducted with breast cancer patients who participated in MBSR. The qualitative data were analysed with the constant comparative method in order to develop a grounded theory.

Results

We could identify a process where at the start of MBSR, patients experienced anticipatory fear for facing the suffering of fellow patients, especially for those who could not be cured anymore. In most women, this fear gradually subsided during the first two sessions. The atmosphere in the MBSR training was experienced as safe and supportive, providing a context where participants could connect with and trust one another. In turn, this facilitated participants to learn from one another.

Conclusions

Our findings do not only show that the peer group facilitates the learning process in MBSR, but the MBSR also seemed to provide an atmosphere that promotes the experienced social support in participants. In addition, the results emphasize the importance for mindfulness teachers to acknowledge and explore the fear for facing fellow patients in the group. Future research should examine whether the results are generalizable to patients with other cancer types.

Mindfulness-Based Stress Reduction for lung cancer patients and their partners: Results of a mixed methods pilot study

BACKGROUND

Lung cancer patients and partners show high rates of impaired quality of life and heightened distress levels. Mindfulness-Based Stress Reduction has proven to be effective in reducing psychological distress in cancer patients. However, studies barely included lung cancer patients.

AIM

We examined whether Mindfulness-Based Stress Reduction might be a feasible and effective intervention for patients with lung cancer and partners.

DESIGN

Mindfulness-Based Stress Reduction is a training in which mindfulness practices are combined with psycho-education to help participants cope with distress. In this mixed methods pilot study, questionnaires on psychological distress and quality of life were administered before, directly after and 3 months after the Mindfulness-Based Stress Reduction training, in combination with semi-structured interviews.

SETTING/PARTICIPANTS

Patients with lung cancer and partners were recruited at one tertiary care academic medical centre. A total of 19 lung cancer patients and 16 partners participated in the Mindfulness-Based Stress Reduction training.

RESULTS

Most patients were diagnosed with advanced stage lung cancer. Vast majority completed the training. Those receiving anti-cancer treatment did not miss more sessions than patients who were not currently treated. Patients and partners felt positive about participating in a peer group and with their partner. Among participants no significant changes were found in psychological distress. Caregiver burden in partners decreased significantly after following Mindfulness-Based Stress Reduction. The qualitative analysis showed that the training seemed to instigate a process of change in participants.

CONCLUSION

The Mindfulness-Based Stress Reduction training seemed to be feasible for patients with lung cancer and their partners. A randomized controlled trial is needed to examine the effectiveness of Mindfulness-Based Stress Reduction in reducing psychological distress in lung cancer patients and partners.

The impact of mindfulness-based interventions on symptom burden, positive psychological outcomes, and biomarkers in cancer patients

Research on the use of mindfulness-based stress reduction and related mindfulness-based interventions (MBIs) in cancer care has proliferated over the past decade. MBIs have aimed to facilitate physical and emotional adjustment to life with cancer through the cultivation and practice of mindfulness (ie, purposeful, nonjudgmental, moment-to-moment awareness). This descriptive review highlights three categories of outcomes that have been evaluated in MBI research with cancer patients - namely, symptom reduction, positive psychological growth, and biological outcomes. We also examine the clinical relevance of each targeted outcome, while describing recently published original studies to highlight novel applications of MBIs tailored to individuals with cancer. Accumulating evidence suggests that participation in a MBI contributes to reductions in psychological distress, sleep disturbance, and fatigue, and promotes personal growth in areas such as quality of life and spirituality. MBIs may also influence markers of immune function, hypothalamic-pituitary-adrenal axis regulation, and autonomic nervous system activity, though it remains unclear whether these biological changes translate to clinically important health benefits. We conclude by discussing methodological limitations of the extant literature, and implications of matching MBIs to the needs and preferences of cancer patients. Overall, the growing popularity of MBIs in cancer care must be balanced against scientific evidence for their impact on specific clinical outcomes.
