Cognitive behavioral stress management effects on psychosocial and physiological adaptation in women undergoing treatment for breast cancer

BRIEF REPORT: Assessing Adherence and Competence in Delivering Telehealth Group Cognitive Behavioral Stress Management

Treatment fidelity, or consistent therapist adherence and competence in intervention delivery, is an important component of intervention design and dissemination. Yet, few systems have been developed to assess fidelity in telepsychology and related remotely-delivered intervention venues. We sought to modify and evaluate a fidelity coding approach for a videoconference-delivered group Cognitive Behavioral Stress Management (CBSM) intervention. Although validated rating systems for treatment fidelity exist, they typically focus on individual therapy and are inappropriate for the structure of group stress management interventions. We modified the RAND Corporation Fidelity Coding Guide, which was initially designed for audiorecorded group Cognitive Behavioral Therapy, for applicability to videotaped sessions of CBSM. Two raters applied the resulting CBSM Coding Guide to 146 session recordings taken from a CBSM trial for persons with chronic fatigue syndrome and their partners, with 40% of sessions double-coded. Reliability for 8 adherence items and 15 competence items was moderate overall (average k w = .751) with 20 of the 23 items demonstrating at least moderate interrater reliability (i.e., k w > .600). Three items that did not meet this cut-off would benefit from more extensive operationalization and rater training. Our adapted system provides a means of assessing adherence and competence variables to validate the delivery of CBSM, and of associating these with positive treatment outcomes to isolate the 'active ingredients' of CBSM. Further, the successful modification and application of the RAND Corporation Fidelity Coding Guide supports the adaptation of this system for a diverse range of remotely delivered cognitive behavioral group therapies.

Mechanisms of stress-attributed breast cancer incidence and progression

Breast cancer is the most commonly diagnosed cancer and the second leading cause of cancer deaths in women, with psychosocial stress commonly cited by patients as one of its causes. While there is conflicting epidemiological evidence investigating the association between psychosocial stress and breast cancer incidence and progression, there is reason to believe that interventions aimed at reducing stress pharmacologically or psychologically may improve breast cancer outcomes. The aim of this review is to discuss the molecular and biological mechanisms of stress-attributed breast cancer incidence and progression, including the induction of the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic nervous system (SNS), as well as decreased immune function and stress hormone-induced resistance to chemotherapy. Moreover, these mechanisms have been cited as potential therapeutic targets of pharmacologic and psychological interventions that may improve the care, well-being and survival of breast cancer patients. Further research is recommended to investigate whether interventions in the primary care setting for women with risk factors for breast cancer development may lead to a decreased incidence of invasive breast tumors.

Treatment of Psychological Symptoms in Patients with Cystic Fibrosis

The aim of this article is to identify and illustrate the most used psychological techniques in the field of cystic fibrosis (CF) and to help clinicians choose the most appropriate strategy among various possibilities. The disease and its medical treatments can be difficult to tolerate and can cause anxiety about health status or feelings of hopelessness and stress. The prevalence of depression and anxiety is 2.3 times higher in adults with CF than in community samples. A strong correlation has been identified between elevated psychological distress and unfavorable health outcomes, including, among others, impaired lung function, reduced BMI, an increased incidence of pulmonary exacerbations, and an elevated risk of transplantation. The use of psychological interventions is useful in addressing these common distresses in CF patients. Aware of the necessity of identifying efficacious interventions for all levels of depression and anxiety in CF patients, this study presents an overview of the research on psychological interventions for patients with CF, in order to complement the treatments suggested by the international guidelines on mental health in CF cases. In fact, the aim of this study is to conduct a review and quantitative synthesis of the psychological intervention techniques that are currently available for individuals with CF.

Influence of stress-specific interventions on biomarker levels and cognitive function in cancer patients: Systematic review and meta-analysis

PURPOSE

Cancer patients' psycho-physiological health is seriously affected by long-term exposure to stress. Many studies have explored the impact of stress-specific interventions on cancer patients' biomarker levels and cognitive functions. However, the current research findings are inconsistent, and their statistical power is limited by the small samples. Therefore, we conducted this meta-analysis to verify the effect of stress-specific interventions on cancer patients.

METHODS

The literature involved nine databases from the inception until January 13, 2024, extracted 19 randomized controlled trials (RCTs). Review Manager (RevMan) 5.4 software was used to perform a meta-analysis, and the revised Cochrane risk of bias tool (RoB2) was utilized for quality evaluation.

RESULTS

Nine RCTs were assessed as having a low risk of bias, and others had a moderate risk. The results showed that stress-specific interventions had beneficial effects on patients' subjective cognition but uncertain impacts on their executive function, tumour necrosis factor-α level, morning cortisol level, and no effect on cortisol at other times, interleukin (IL)-10, IL-8, IL-6, IL-1, and C-reactive protein.

CONCLUSION

More rigorous studies are required to elucidate the influence of stress-specific interventions on biomarker levels. The potential mechanism by which stress-specific interventions affect the cancer patient's cognitive function remains unclear.

Humanistic Health Management and Cancer: Associations of Psychology, Nutrition, and Exercise with Cancer Progression and Pathogenesis

The incidence rate of cancer is increasing year by year due to the aging of the population, unhealthy living, and eating habits. At present, surgery and medication are still the main treatments for cancer, without paying attention to the impact of individual differences in health management on cancer. However, increasing evidence suggests that individual psychological status, dietary habits, and exercise frequency are closely related to the risk and prognosis of cancer. The reminder to humanity is that the medical concept of the unified treatment plan is insufficient in cancer treatment, and a personalized treatment plan may become a breakthrough point. On this basis, the concept of "Humanistic Health Management" (HHM) is proposed. This concept is a healthcare plan that focuses on self-health management, providing an accurate and comprehensive evaluation of individual lifestyle habits, psychology, and health status, and developing personalized and targeted comprehensive cancer prevention and treatment plans. This review will provide a detailed explanation of the relationship between psychological status, dietary, and exercise habits, and the regulatory mechanisms of cancer. Intended to emphasize the importance of HHM concept in cancer prevention and better prognostic efficacy, providing new ideas for the new generation of cancer treatment.

Effects of Resilience and Emotion Regulation on Perceptions of Positive and Negative Life Changes in Cancer Survivors: A Longitudinal Study

BACKGROUND

While many studies have investigated the sociodemographic, clinical, and psychosocial factors associated with perceived positive change after cancer, longitudinal work examining how emotion regulation, and resilience impact perceptions of life change among newly diagnosed cancer survivors is lacking.

PURPOSE

This study examined the prevalence of perceived positive and negative life changes following cancer and explored the role of emotion regulation and resilience on perceived change over 6 months.

METHODS

Data from 534 recent survivors of breast, prostate, or colorectal cancer (Mage = 59.3, 36.5% male) collected at baseline (Time 1) and 6-month follow-up (Time 2) were analyzed. Multivariate linear regressions were estimated separately to examine if resilience or emotion regulation were associated with perceived change at Time 2 after controlling for relevant sociodemographic and psychosocial measures.

RESULTS

At both time points, greater than 90% of participants reported at least one perceived positive change while fewer than a third reported a negative change. Indices of emotion regulation and resilience were positively related to perceived positive change at both time points and negatively related to perceived negative change at Time 1. Emotion regulation but not resilience was negatively associated with perceived negative change at Time 2.

CONCLUSIONS

Findings suggest that cancer survivors who are less resilient and struggle with emotion regulation are more susceptible to perceptions of fewer positive and greater negative life changes after cancer. As such, psychosocial interventions should be developed to promote resilience and emotional regulation in cancer survivors.

Peri-operative individually tailored psychological intervention in breast cancer patients improves psychological indices and molecular biomarkers of metastasis in excised tumors

Perioperative stress and inflammatory signaling can invigorate pro-metastatic molecular processes in patients' tumors, potentially worsening long-term survival. Yet, it is unknown whether pre-operative psychotherapeutic interventions can attenuate such effects. Herein, three weeks before surgery, forty women diagnosed with stage I-III invasive ductal/lobular breast carcinoma were randomized to a 6-week one-on-one psychological intervention (6 meetings with a medical psychologist and bi-weekly phone calls) versus standard nursing-staff-attention. The intervention protocol was individually tailored based on evaluation of patients' emotional, cognitive, physiological, and behavioral stress response-patterns, and also included psychoeducation regarding medical treatments and recruitment of social support. Resected primary tumors were subjected to whole-genome RNA sequencing and bioinformatic analyses, assessing a priori hypothesized cancer-relevant molecular signatures. Self-report questionnaires (BSI-18, Hope-18, MSPSS, and a stress-scale) were collected three (T1) and one (T2) week before surgery, a day before (T3) and after (T4) surgery, and three weeks (T5) and 3-months (T6) following surgery. The intervention reduced distress (GSI), depression, and somatization scores (BSI-18: p < 0.01, p < 0.05, p < 0.05; T5 vs. T1). Additionally, tumors from treated patients (vs. controls) showed: (i) decreased activity of transcription control pathways involved in adrenergic and glucocorticoid signaling (CREB, GR) (p < 0.001), pro-inflammatory signaling (NFkB) (p < 0.01), and pro-malignant signaling (ETS1, STAT and GATA families) (p < 0.001, p < 0.01, p < 0.005); (ii) increased M1 macrophage polarization (p < 0.05), and CD4+ T cell activity (p < 0.01); and an unexpected increase in epithelial-to-mesenchymal-transition (EMT) signature (p < 0.005). This is the first randomized controlled trial to show beneficial effects of a psychological perioperative intervention on tumor pro-metastatic molecular biomarkers.

Psychosocial well-being among patients with malignant pleural mesothelioma

OBJECTIVES

The investigators conducted a psychosocial needs assessment of mesothelioma patients through self-report measures of quality of life (QOL), coping, depression, and social support.

METHODS

Patients with malignant pleural mesothelioma (MPM) (N = 67) completed a battery of assessments at a single timepoint after being approached during routine medical oncology clinic appointments or by letter.

RESULTS

Participants were predominately male (70.0%; n = 47) and ranged in age from 35 to 83 years old (M = 65.61, SD = 9.71). Most participants were white (88.0%; n = 59), and 10.0% (n = 7) were identified as Hispanic. The majority were married or living with a partner (93.0%; n = 62) and had some college or more education (64.0%; n = 43). Fourteen percent of participants (n = 11) endorsed significantly elevated depression symptoms. No significant demographic or clinical differences in depressed compared to nondepressed participants were observed, with a trend toward those identifying as Hispanic and those who were divorced as being more likely to be depressed. For the total sample, the most frequently endorsed coping strategies were active coping, emotional support, and acceptance.

SIGNIFICANCE OF RESULTS

The present study did not identify any clear correlates of depression or QOL among patients with MPM. This research contributes to the small literature on psychosocial functioning in patients with MPM and provides putative directions for future larger studies and the development of interventions to provide appropriate support to diverse patients with MPM.

Integrative Oncology Approaches to Reduce Recurrence of Disease and Improve Survival

PURPOSE OF REVIEW

After a cancer diagnosis, patients ask what they can do in addition to the recommended treatments to increase their survival. Many turn to integrative medicine modalities and lifestyle changes to improve their chances of survival. Numerous studies have demonstrated that lifestyle changes can significantly improve survival rates for cancer patients. Less support exists for the use of natural products or supplements to improve cancer survival. In this manuscript, we review key findings and evidence in the areas of healthy eating habits, physical activity, stress management and social support, and sleep quality, as well as natural products and supplements as they relate to the cancer recurrence and survival.

RECENT FINDINGS

While more research is needed to fully understand the mechanisms underlying the associations between lifestyle changes and cancer survival, findings suggest that lifestyle modifications in the areas of diet, physical activity, stress management and social support, and sleep quality improve clinical cancer outcomes. This is especially true for programs that modify more than one lifestyle habit. To date, outside of supplementing with vitamin D to maintain adequate levels, conflicting conclusion within the research remain regarding the efficacy of using natural products or supplement to improve cancer recurrence of disease or cancer survival. A call for further research is warranted. Lifestyle screening and counseling should be incorporated into cancer treatment plans to help improve patient outcomes. While the scientific community strives for the pursuit of high-quality research on natural products to enhance cancer survival, transparency, dialogue, and psychological safety between patients and clinicians must continue to be emphasized. Proactive inquiry by clinicians regarding patients' supplement use will allow for an informed discussion of the benefits and risks of natural products and supplements, as well as a re-emphasis of the evidence supporting diet and other lifestyle habits to increase survival.

Inside the Biology of the β3-Adrenoceptor

Since the first discovery in 1989, the β3-adrenoceptor (β3-AR) has gained great attention because it showed the ability to regulate many physiologic and metabolic activities, such as thermogenesis and lipolysis in brown and white adipose tissue, respectively (BAT, WAT), negative inotropic effects in cardiomyocytes, and relaxation of the blood vessels and the urinary bladder. The β3-AR has been suggested as a potential target for cancer treatment, both in adult and pediatric tumors, since under hypoxia its upregulation in the tumor microenvironment (TME) regulates stromal cell differentiation, tumor growth and metastases, signifying that its agonism/antagonism could be useful for clinical benefits. Promising results in cancer research have proposed the β3-AR being targeted for the treatment of many conditions, with some drugs, at present, undergoing phase II and III clinical trials. In this review, we report the scientific journey followed by the research from the β3-Ars' discovery, with focus on the β3-Ars' role in cancer initiation and progression that elects it an intriguing target for novel antineoplastic approaches. The overview highlights the great potential of the β3-AR, both in physiologic and pathologic conditions, with the intention to display the possible benefits of β3-AR modulation in cancer reality.

Videoconference-delivered group Cognitive Behavioral Stress Management for ME/CFS patients who present with severe PEM: A randomized controlled trial

Background

In Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS), post-exertional malaise (PEM) is associated with greater distress and symptoms. Cognitive Behavioral Stress Management (CBSM) has demonstrated beneficial effects for ME/CFS and may mitigate stress-related triggers of PEM. We tested a virtual CBSM intervention to increase access, and we report on its effects on stress and symptoms in ME/CFS patients with severe PEM.

Methods

Data were from a randomized controlled trial (NCT01650636) comparing 10-week videoconference-delivered group CBSM (V-CBSM, n=75) to a 10-week Health Information active control (V-HI, n=75) in Fukuda criteria ME/CFS patients (71 classified as highPEM, 79 lowPEM). Linear regression explored PEM-by-Treatment interactions on overall symptom frequency and intensity, perceived stress, and fatigue-specific interference and intensity, at 5-month follow-up. Logistic regression tested V-CBSM effects on 5-month PEM status. Analyses controlled for age, gender, race/ethnicity, mode of symptom onset, and time since diagnosis.

Results

The sample was middle-aged (47.96±10.89 years), mostly women (87%) and non-Hispanic White (65%), with no group differences on these variables or baseline PEM. For highPEM patients, V-CBSM (versus V-HI) demonstrated medium to large effects on follow-up symptom frequency, symptom intensity, fatigue interference, and fatigue intensity (p's < .05) and trending to significant reductions in perceived stress (p =.07). Differences were not evident for lowPEM patients. Treatment predicted follow-up PEM status at a trend (p = .058), with patients receiving V-CBSM demonstrating half the risk of highPEM classification versus V-HI.

Conclusions

V-CBSM demonstrates benefits for ME/CFS patients presenting with severe PEM and may reduce the expression of PEM over time.

Depression, Cancer, Inflammation, and Endogenous Opioids: Pathogenic Relationships and Therapeutic Options

Endogenous opioids and their associated receptors form a system that maintains survival by positively reinforcing behaviors that are vital to life. Cancer and cancer treatment side effects capitalize on this system pathogenically, leading to maladaptive biological responses (e.g., inflammation), as well as cognitive and emotional consequences, most notably depression. Psychologists who treat people with cancer frequently find depression to be a primary target for intervention. However, in people with cancer, the etiology of depression is unique and complex. This complexity necessitates that psycho-oncologists have a fundamental working knowledge of the biological substrates that underlie depression/cancer comorbidity. Building on other chapters in this volume pertaining to cancer and endogenous opioids, this chapter focuses on the clinical applications of basic scientific findings.

Emotional Distress in Portuguese Cancer Patients: The Use of the Emotion Thermometers (ET) Screening Tool

Cancer patients may experience significant distress. The "Emotion Thermometers" (ETs) are a short visual analogue scale used to screen patients for psychosocial risk. This study aimed to assess emotional distress in a large sample of cancer patients attending psychological services at an non-governmental organization (NGO), and to explore factors that may contribute to it. The ETs were answered by 899 cancer patients. They were, on average, 59.9 years old, the majority were female, had breast cancer, were under treatment or were disease-free survivors, and reported high levels of emotional distress, above the cut-off (≥5). A Generalized Linear Model was used to measure the association between the level of distress, age, gender, disease phase and 33 items of the problem list. Four items-sadness, depression, sleep and breathing-were found to be significantly related to a higher level of distress. Additionally, women and patients who were in the palliative phase also had significantly higher levels of distress. The results confirm the need for early emotional screening in cancer patients, as well as attending to the characteristics of each patient. Additionally, they highlight the utility of the ETs for the clinical practice, allowing to optimize the referral to specialized psychosocial services.

Do cancer curvivors and metavivors have distinct needs for stress management intervention? Retrospective analysis of a mind-body survivorship program

PURPOSE

Cancer "curvivors" (completed initial curative intent treatment with surgery, radiation, chemotherapy, and/or other novel therapies) and "metavivors" (living with metastatic or chronic, incurable cancer) experience unique stressors, but it remains unknown whether these differences impact benefits from mind-body interventions. This study explored differences between curvivors and metavivors in distress (depression, anxiety, worry) and resiliency changes over the course of an 8-week group program, based in mind-body stress reduction, cognitive-behavioral therapy (CBT), and positive psychology.

METHODS

From 2017-2021, 192 cancer survivors (83% curvivors; 17% metavivors) completed optional online surveys of resiliency (CES) and distress (PHQ-8, GAD-7, PSWQ-3) pre- and post- participation in an established clinical program. Mixed effect regression models explored curvivor-metavivor differences at baseline and in pre-post change.

RESULTS

Compared to curvivors, metavivors began the program with significantly more resilient health behaviors (B = 0.99, 95% CI[0.12, 1.86], p = .03) and less depression (B = -2.42, 95%CI[-4.73, -0.12], p = .04), with no other significant differences. Curvivors experienced significantly greater reductions in depression (curvivor-metavivor difference in strength of change = 2.12, 95% CI [0.39, 3.83], p = .02) over the course of the program, with no other significant differences. Neither virtual delivery modality nor proportion of sessions attended significantly moderated strength of resiliency or distress change.

CONCLUSION

Metavivors entering this mind-body program had relatively higher well-being than did curvivors, and both groups experienced statistically comparable change in all domains other than depression. Resiliency programming may thus benefit a variety of cancer survivors, including those living with incurable cancer.

Psychosocial interventions reduce cortisol in breast cancer patients: systematic review and meta-analysis

Introduction

Cancer initiation, progression and recurrence are intricate mechanisms that depend on various components: genetic, psychophysiological, or environmental. Exposure to chronic stress includes fear of recurrence that can affect biological processes that regulate immune and endocrine systems, increase cancer risk, and influence the survival rate. Previous studies show that psychological interventions might influence the level of cortisol that has been extensively used as a biomarker for measuring hypothalamic-pituitary-adrenal axis functioning and body's immunity response. This meta-analysis aimed to provide a quantitative scrutiny of the effect of certain types of psychosocial interventions on cortisol as a neuroendocrine biomarker in saliva or blood and might predict breast cancer (BC) progression.

Methods

A literature search was performed in the following databases: PubMed, The Cohrane Library, Scopus, WOS, PsychInfo, Google Scholar, Ovid Science Direct. After methodical selection of originally generated 2.021 studies, the search yielded eight articles that met inclusion criteria. All these studies explored effects of psychosocial interventions that measured cortisol in total of 366 participants with BC, stages 0-IV, in randomized control trial or quasi experimental study design setting. We applied random effects model to conduct meta-analyses on the parameters of salivary and plasma cortisol and used PRISMA Guidelines as validated methodology of investigation to report the results.

Results

Eight studies selected for meta-analysis have shown the reduction of cortisol level due to applied psychosocial intervention. The random effects model showed that interventions produced large effect sizes in reductions of cortisol in blood (Cohen's d = -1.82, 95% Confidence Interval (CI): -3.03, -0.60) and slightly less in saliva (d = -1.73, 95%CI: -2.68, -0.78) with an overall effect of d = -1.76 (95%CI: -2.46, -1.07).

Conclusion

Our study concluded that certain types of psychosocial interventions reduce cortisol (indicator of chronic stress) in patients with BC. Application of specific psychosocial support as adjuvant non-invasive therapy for affected females with BC at all phases of treatment could contribute to more cost-effective health care.

Effect of cognitive behavioral stress management on anxiety, depression, and quality of life in colorectal cancer patients post tumor resection: a randomized, controlled study

OBJECTIVE

Cognitive behavioral stress management (CBSM) is a psychotherapy helping individuals develop adaptive behaviors, whose application in colorectal cancer (CRC) is rare. This randomized, controlled study intended to explore the effect of CBSM on anxiety, depression, and quality of life in CRC patients post tumor resection.

METHODS

One hundred and sixty CRC patients who received tumor resection were randomized (1:1) to receive weekly CBSM or usual care (UC) for 10 weeks after discharge (120 min for each session). Hospital Anxiety and Depression Scale (HADS) and Quality of Life Questionnaire-Core 30 (QLQ-C30) of each patient were assessed after randomization (M0), one month (M1), three months (M3), and six months (M6).

RESULTS

CBSM realized decreased HADS-anxiety scores at M1 (P = 0.044), M3 (P = 0.020), M6 (P = 0.003) compared to UC, so did anxiety rates at M3 (28.0% vs. 43.6%, P = 0.045), M6 (25.7% vs. 42.5%, P = 0.035), HADS-depression scores at M3 (P = 0.017), M6 (P = 0.005), and depression rates at M3 (25.3% vs. 41.0%, P = 0.040), M6 (22.9% vs. 41.1%, P = 0.020). Concerning the quality of life, CBSM achieved elevated QLQ-C30 global health status scores at M6 (P = 0.008), QLQ-C30 functions scores at M3 (P = 0.047), M6 (P = 0.031), and decreased QLQ-C30 symptoms scores at M3 (P = 0.048) and M6 (P = 0.039) compared with UC. By subgroup analyses, CBSM had a better utility on relieving anxiety, depression and improving quality of life in patients with higher education level and patients receiving adjuvant chemotherapy.

CONCLUSION

CBSM program alleviates anxiety, depression, and elevates quality of life in CRC patients post tumor resection.

The relationship between hope, medical expenditure and survival among advanced cancer patients

Introduction

Among those with advanced illness, higher levels of hope may offer physiological benefits. Yet, greater levels of hope may also encourage aggressive treatments. Therefore, higher levels of hope may lead to greater healthcare utilization, higher expenditure, and longer survival. We test these hypotheses among patients with advanced cancer.

Methods

A secondary data analysis from a cross-sectional survey of 195 advanced cancer patients with high mortality risk linked to subsequent healthcare utilization (outpatient, day surgeries, non-emergency admissions), health expenditures, and death records. The survey collected data on hope, measured generally by the Herth Hope Index (HHI) and more narrowly by two questions on illness-related hope. Generalized linear regression and Cox models were used to test our hypotheses.

Results

142 (78%) survey participants died during the period of analysis, with close to half (46%) doing so within a year of the survey. Contrary to expectation, HHI scores did not have a significant association with healthcare utilization, expenditure or survival. Yet, illness-related hope, defined as those who expected to live at least 2 years, as opposed to the likely prognosis of 1 year or less as determined by the primary treating oncologist, had 6.6 more planned hospital encounters (95% CI 0.90 to 12.30) in the 12-months following the survey and 41% lower mortality risk (hazard ratio: 0.59, 95% CI 0.36 to 0.99) compared to those who were less optimistic. Secondary analysis among decedents showed that patients who believed that the primary intent of their treatment is curative, had higher total expenditure (S$30,712; 95% CI S$3,143 to S$58,282) in the last 12 months of life than those who did not have this belief.

Conclusion

We find no evidence of a relationship between a general measure of hope and healthcare utilization, expenditure, or survival among advanced cancer patients. However, greater illness-related hope is positively associated with these outcomes.

Potential cardioprotective and anticancer effects of carvedilol either free or as loaded nanoparticles with or without doxorubicin in solid Ehrlich carcinoma-bearing mice

AIM

The aim of this study was to investigate the potential cardioprotective and anti-cancer effects of carvedilol (CAR) either free or as loaded nano-formulated with or without doxorubicin (DOX) in solid Ehrlich carcinoma (SEC)-bearing mice. It focused on assessment of cardiac damage, drug resistance, apoptosis, oxidative stress status, angiogenesis and proliferation.

METHODS

CAR was loaded into poly-D,L lactic-co-glycolic acid)PLGA(or Niosomes. SEC was induced in female albino mice as an experimental model of breast cancer. Seventy-two mice were randomly divided into 9 equal groups (Normal control, Untreated-SEC, SEC + DOX, SEC + CAR-free, SEC + CAR-PLGA, SEC + CAR-Niosomes, SEC + DOX + CAR-free, SEC + DOX + CAR-PLGA and SEC + DOX + CAR-Niosomes). Tumor volume and survival rate were recorded. On day 28 from tumor inoculation, mice were sacrificed, and blood samples were collected for determination of serum lactate dehydrogenase (LDH) and creatine kinase-MB (CK-MB). One part from tumor tissues was prepared for assessment of multidrug resistance protein-1 (MDR-1), caspase-3, reduced glutathione (GSH) and malondialdehyde (MDA), while the other part was processed for histopathological examination and immunohistochemical expression of vascular endothelial growth factor (VEGF) and Ki-67.

RESULTS

There was non-significant difference between CAR-free, CAR-PLGA and CAR-Niosomes as anticancer either alone or when combined with DOX. However, CAR-free demonstrated potential cardioprotective effects against cardiac damage mediated by cancer or DOX that have been enhanced using CAR-PLGA or CAR-Niosomes, but that of Niosomes outperformed them both.

CONCLUSION

CAR could be used as an adjuvant therapy with DOX, especially when nanoformualted with PLGA and even better with Niosomes, without compromising its cytotoxicity against cancer cells and preventing its cardiotoxic impacts.

Effects of Psychosocial Interventions for Patients with Breast Cancer: A Meta-analysis

Objective

This study involved a meta-analysis of South Korean studies regarding psychosocial interventions for patients with breast cancer to provide basic data to support the development of an integrated healthcare service model.

Methods

Randomized controlled studies with a pretest-posttest design were selected, and those presenting means, standard deviations, and standardized mean differences were included. For quality evaluation and heterogeneity testing, the Jadad scale and the Q-value and I2 were used. To estimate the effect size of each study, Hedge's g was used. Publication bias was analyzed with the Funnel plot and Egger's regression test.

Results

Of the 28 studies selected for the, meta-analysis was performed on eight. The total number of datasets included in the meta-analysis was 33. The evaluation based on the Jadad scale revealed no significant inter-rater variation (p = 0.35). The mean number of sessions was 7.93 and the mean intervention time was 13.2 hours. The interventions were mostly administered in a group structure (94%) and, regarding the type, they were categorized as integrated (36.4%), cognitive (30.3%), and meditation (24.2%). The mean effect size was 1.21 against no treatment group.

Conclusion

The analyzed studies showed heterogeneity, with a corresponding asymmetry found on the Funnel plot. Despite the heterogeneity and publication bias, the mean effect size was significantly large. Cognitive interventions, meditation, and psychological education programs are expected to assist in reducing negative emotions and enhancing quality of life in patients with breast cancer.

Stress Management Interventions to Facilitate Psychological and Physiological Adaptation and Optimal Health Outcomes in Cancer Patients and Survivors

Cancer diagnosis and treatment constitute profoundly stressful experiences involving unique and common challenges that generate uncertainty, fear, and emotional distress. Individuals with cancer must cope with multiple stressors, from the point of diagnosis through surgical and adjuvant treatments and into survivorship, that require substantial psychological and physiological adaptation. This can take a toll on quality of life and well-being and may also promote cellular and molecular changes that can exacerbate physical symptoms and facilitate tumor growth and metastasis, thereby contributing to negative long-term health outcomes. Since modifying responses tostressors might improve psychological and physiological adaptation, quality of life, and clinical health outcomes, several randomized controlled trials have tested interventions that aim to facilitate stress management. We review evidence for the effects of stress management interventions on psychological and physiological adaptation and health outcomes in cancer patients and survivors and summarize emerging research in the field to address unanswered questions.

Psychological interventions for women with non-metastatic breast cancer

BACKGROUND

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

OBJECTIVES

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

SELECTION CRITERIA

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

DATA COLLECTION AND ANALYSIS

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

MAIN RESULTS

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

AUTHORS' CONCLUSIONS

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

Therapeutic yoga reduces pro-tumorigenic cytokines in cancer survivors

INTRODUCTION

Chronic inflammation can remain many years after the completion of cancer treatment and is associated with cancer recurrence. The purpose of this study was to examine how a 16-week therapeutic yoga program (TYP) modulates the cytokine profile in heterogeneous cancer survivors.

METHODS

Eligible participants were 18 years of age or older and clinically diagnosed with cancer. Consenting participants were asked to attend three, 75-min sessions weekly of TYP with meditation. Seventeen patients provided blood samples at baseline and end of study. Eight cytokines (interferon (IFN)-γ; interleukin (IL)-1b, IL-1ra, IL-4, IL-6, IL-8, IL-10; and tumor necrosis factor (TNF)-α), three receptors (sIL-6R, sTNFRI, sTNFRII), and C-reactive protein (CRP) were quantified.

RESULTS

Patients were 59.6 ± 7.3 years old; over half (56%) were overweight or obese BMI ≥ 25 kg/m2); majority were female (71%) and breast cancer survivors (65%), of which 44% were Hispanic. Marked reductions were observed in all cytokines except IL-4, with significant reductions (p < 0.05) found in IL-1b (- 13%) and IL-1ra (- 13%). No significant changes were observed in soluble cytokine receptors or CRP.

CONCLUSIONS

TYP led to significant reduction in circulating cytokines associated with chronic inflammation in a heterogeneous sample of cancer survivors.

Effects of a randomized-controlled trial of cognitive behavioral stress management: Psychosocial adaptation and immune status in men with early-stage prostate cancer

OBJECTIVE

Targets of intervention in cognitive behavioral stress management (CBSM), such as benefit finding (BF) and perceived stress management skills (PSMS), may counteract stress-related changes that impact the immune system. This study tested whether BF, PSMS, and optimism influence the effects of CBSM on immune status in men with prostate cancer.

METHODS

Men with prostate cancer were randomized to receive CBSM or a psychoeducation (PE) control comparison (NCT05486754). Life Orientation Test-Revised assessed baseline optimism. The Benefit Finding Scale and Measure of Current Status measured BF and PSMS after CBSM. T-cells and T-helper cells captured immune status change at baseline and 6-months post-CBSM. MPlus and SPSS (PROCESS) tested condition effects and moderated mediation, controlling for covariates.

RESULTS

256 primarily middle-aged, White Non-Hispanic or Hispanic men enrolled. PSMS mediated CBSM effects on T-cell and T-helper cell percentage, such that T-cell and T-helper cell percentages were reduced in men in CBSM versus PE via PSMS. Optimism moderated this mediation with the mediating effect of PSMS only observed among men with average optimism versus those with low or high optimism.

CONCLUSION

Baseline psychological characteristics, as well as limited specificity of immune measurement, could explain the conditional effects in this sample.

Cortisol levels in rural Latina breast cancer survivors participating in a peer-delivered cognitive-behavioral stress management intervention: The Nuevo Amanecer-II RCT

Background

Compared to their White counterparts, Latina breast cancer survivors have poorer survival rates and health-related quality of life, and higher rates of depression and anxiety which may be a result of chronic stress. Chronic stress impacts the hypothalamic-pituitary-adrenal (HPA) axis, resulting in cortisol dysregulation which may be associated with breast cancer survival. However, cortisol levels and cortisol profiles of Latina breast cancer survivors are poorly characterized due to their underrepresentation in biomedical research.

Objective

The objective of this study was to describe cortisol levels and patterns of cortisol secretions in rural Latina breast cancer survivors participating in an RCT study of Nuevo Amanecer-II, an evidence-based peer-delivered cognitive behavioral stress management intervention.

Methods

Participant-centered recruitment and collection strategies were used to obtain biospecimens for cortisol analysis. Nine saliva samples (3/day for 3 days) and a hair sample were obtained at baseline and 6-months (3-months post-intervention). We describe cortisol levels and profiles, explore correlations of biomarkers with self-report measures of stress and psychological distress, and compare women who received the intervention with a delayed intervention group on biomarkers of stress. Mean hair cortisol concentration (HCC) was used to assess chronic stress. Based on daily measures of cortisol (awakening, 30 min post-awakening, and bedtime), we calculated three summary measures of the dynamic nature of the cortisol awakening response (CAR): 1) the CAR slope, 2) whether CAR demonstrates a percent change ≥40, and 3) total daily cortisol output (AUCg). Linear and log-binomial regression, accounting for multiple samples per participant, were used to compare cortisol measures at 6-month follow-up by treatment arm.

Results

Participants (n = 103) were from two rural California communities; 76 provided at least one saliva sample at baseline and follow-up and were included in the analysis. At baseline, mean age was 57 years, mean years since diagnosis was 2 years, 76% had a high school education or less, and 34% reported financial hardship. The overall median CAR slope was 0.10, and median cortisol AUCg (in thousands) was 11.34 (range = 0.93, 36.66). Mean hair cortisol concentration was 1751.6 pg/mg (SD = 1148.6). Forty-two percent of samples had a ≥40% change in CAR. We found no statistically significant correlations between the cortisol measures and self-reported measures of stress and psychological distress. At follow-up, no differences were seen in HCC (mean difference between intervention and control: -0.11, 95% CI -0.48, 0.25), CAR slope (0.001, 95% CI -0.005, 0.008), cortisol AUCg (-0.15, 95% CI -0.42, 0.13), or ≥40% change in CAR (prevalence ratio 0.87, 95% CI 0.42, 1.77) between treatment arms.

Conclusion

Our findings of flattened cortisol profiles among more than half of the sample suggest potential HPA-axis dysregulation among rural Spanish-speaking Latina breast cancer survivors that merits further study due to its implications for long-term survival.

The influence of psychological interventions on surgical outcomes: a systematic review

BACKGROUND

An amplified and/or prolonged surgical stress response might overcome the organs' functional reserve, thus leading to postoperative complications. The aim of this systematic literature review is to underline how specific psychological interventions may contribute to improve surgical outcomes through the positive modulation of the surgical stress response in surgical patients.

METHODS

We conducted a comprehensive literature search in the Cochrane Register of Controlled Trials, PubMed, EMBASE, Scopus, PsycINFO, and CINAHL databases. Only studies published in English from Jan 2000 to Apr 2022 and reporting pain and/or anxiety among outcome measures were included in the review. The following psychological interventions were considered: (1) relaxation techniques, (2) cognitive-behavioral therapies, (3) mindfulness, (4) narrative medicine, (5) hypnosis, and (6) coping strategies.

RESULTS

Among 3167 records identified in the literature, 5 papers were considered eligible for inclusion in this review because reporting the effects that psychological features have on neurochemical signaling during perioperative metabolic adaptation and those metabolic and clinical effects that the psychological interventions had on the observed population.

CONCLUSION

Our findings confirm that psychological interventions may contribute to improve surgical outcomes via the positive influence on patients' metabolic surgical stress response. A multidisciplinary approach integrating physical and non-physical therapies can be considered a good strategy to successfully improve surgical outcomes in the perioperative period.

The effect of cognitive behavioral stress management on perceived stress, biological stress markers and weight loss/regain, from a diet-induced weight loss program: A randomized controlled trial

Obesity and psychosocial stress are inter-related chronic conditions which lead to increased cardiovascular morbidity and mortality. The aim of this parallel randomized controlled trial was to determine whether the addition of a structured cognitive behavioral stress management (CBSM) on to a commercial online weight loss program, resulted in greater weight loss than the standard weight loss program in isolation. Eligible participants were adults between the ages 18-65, BMI 30-45 kg/m2, with no major systemic or psychiatric conditions. Seventy-four participants were assigned according to simple randomization using computer generated random numbers to either a 3-month online Weight Watchers® program (n = 36), or Weight Watchers® plus 10 weekly sessions of CBSM (n = 38). The primary outcome was weight at 3 months compared to baseline. Secondary outcomes were weight at 12 months and subjective/objective stress system measures and metabolic markers at 3 and 12 months. The study was powered at 90% to detect a 5 kg difference in weight between the two groups at 3 months. Independent sample t-tests were used to analyze the difference in weight (in kg) between the groups and paired sample t-tests were used to analyze the difference within group at different time intervals. At follow-up, there was no significant difference in weight loss between the groups (1.8 kg, 2.1 kg). However, CBSM was effective in reducing psychological measures of stress (p < 0.05) and salivary cortisol (waking, 20-min post-waking) at 3-months; with the effect on stress persisting at 12-months within the CBSM group. The reduction in PSS at 3 months was significantly greater in the CBSM group (3.84, p = 0.028) compared to WW only group at 3 months. Addition of CBSM to a standard weight loss intervention did not improve the weight loss over the standard approach on its own, but the CBSM intervention improved psychological stress parameters and cortisol secretion in participants living with obesity.

Study design and protocol for tailored Acceptance and Commitment Therapy (ACT) to optimize quality of life in women living with metastatic breast cancer

Women living with metastatic (stage IV) breast cancer face unique challenges, including arduous treatments, side effects, chronic symptom burden, and emotional distress. Nevertheless, most research has paradoxically focused on optimizing quality of life in women with early-stage, non-metastatic breast cancer. Acceptance and Commitment Therapy (ACT) is an evidence-based, third-wave cognitive behavioral therapy that focuses on creating 'a life worth living' by promoting meaning and purpose and optimizing quality of life. ACT may be particularly well-suited for women with metastatic breast cancer as it addresses salient existential concerns, while allowing for the co-occurrence of feelings of grief and loss that are normal and expected when facing a life-limiting prognosis. This manuscript describes the rationale and study design of a pilot randomized controlled trial to develop and assess the feasibility and acceptability of a tailored ACT intervention for women living with metastatic breast cancer. Participants (N = 30) will be randomized 1:1 to either ACT, cognitive behavioral stress management (CBSM), or a usual care control. Both ACT and CBSM are 8-week, group-based interventions that will be delivered online. Primary outcomes are rates of acceptance, retention, and satisfaction. Preliminary effects on variables of interest, including meaning and purpose, psychological flexibility, and several domains of quality of life, will also be examined. Findings will inform the conduct of a full-scale randomized controlled trial of our tailored ACT intervention in women living with metastatic breast cancer.

Cognitive behavioral stress management effects on prenatal anxiety among low-income women

OBJECTIVE

Few studies have tested cognitive behavioral therapy to reduce prenatal anxiety despite substantial empirical support among individuals seeking treatment for anxiety symptoms. We examined whether a brief cognitive behavioral intervention delivered to low-income pregnant women would be efficacious for reducing prenatal anxiety.

METHOD

A sample of 100 primarily ethnic and racial minority pregnant women with subclinical anxiety (74% Latina, 18% Black; Mage = 26.5) were randomized to an 8-week cognitive behavioral stress management (CBSM) intervention (n = 55), or to an attentional control condition (n = 45). Two forms of anxiety (state and pregnancy-specific) were measured at baseline, post-treatment, and at follow-up in the postpartum using the State-Trait Personality Inventory-State and the Pregnancy Related Anxiety scale, respectively. Intent-to-treat (ITT) and completer analyses were conducted using linear mixed models to test mean differences in both forms of anxiety by group assignment and by intervention completion (< 7 vs. ≥ 7 sessions) at post-treatment and follow-up timepoints.

RESULTS

ITT results revealed no intervention Group × Time interactions for state, F(3, 356) = .51, p = .68, or pregnancy-specific anxiety, F(2, 184.39) = .75, p = .47, indicating no intervention effect post-treatment or at follow-up. Completer analyses showed that women who received all intervention content (34.5%) had significantly less state anxiety at post-treatment compared to women who had not completed the intervention, (65.5%; Msessions = 3.62); F(6, 270.67) = 2.35, p = .03, and those in the control condition.

CONCLUSIONS

While we did not find support for the use of CBSM to treat prenatal anxiety among low-income women, those who received a full dose benefited in state anxiety immediately postintervention. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Biobehavioral Pathways and Cancer Progression: Insights for Improving Well-Being and Cancer Outcomes

The relationship between psychosocial factors and cancer has intrigued people for centuries. In the last several decades there has been an expansion of mechanistic research that has revealed insights regarding how stress activates neuroendocrine stress-response systems to impact cancer progression. Here, we review emerging mechanistic findings on key pathways implicated in the effect of stress on cancer progression, including the cellular immune response, inflammation, angiogenesis, and metastasis, with a primary focus on the mediating role of the sympathetic nervous system. We discuss converging findings from preclinical and clinical cancer research that describe these pathways and research that reveals how these stress pathways may be targeted via pharmacological and mind-body based interventions. While further research is required, the body of work reviewed here highlights the need for and feasibility of an integrated approach to target stress pathways in cancer patients to achieve comprehensive cancer treatment.

Stress and cancer: mechanisms, significance and future directions

The notion that stress and cancer are interlinked has dominated lay discourse for decades. More recent animal studies indicate that stress can substantially facilitate cancer progression through modulating most hallmarks of cancer, and molecular and systemic mechanisms mediating these effects have been elucidated. However, available clinical evidence for such deleterious effects is inconsistent, as epidemiological and stress-reducing clinical interventions have yielded mixed effects on cancer mortality. In this Review, we describe and discuss specific mediating mechanisms identified by preclinical research, and parallel clinical findings. We explain the discrepancy between preclinical and clinical outcomes, through pointing to experimental strengths leveraged by animal studies and through discussing methodological and conceptual obstacles that prevent clinical studies from reflecting the impacts of stress. We suggest approaches to circumvent such obstacles, based on targeting critical phases of cancer progression that are more likely to be stress-sensitive; pharmacologically limiting adrenergic-inflammatory responses triggered by medical procedures; and focusing on more vulnerable populations, employing personalized pharmacological and psychosocial approaches. Recent clinical trials support our hypothesis that psychological and/or pharmacological inhibition of excess adrenergic and/or inflammatory stress signalling, especially alongside cancer treatments, could save lives.

The Risk of Psychological Stress on Cancer Recurrence: A Systematic Review

Cancer recurrence is a significant clinical issue in cancer treatment. Psychological stress has been known to contribute to the incidence and progression of cancer; however, its effect on cancer recurrence remains inconclusive. We conducted a systematic review to examine the current evidence from the Medline (PubMed), Embase and Cochrane Library up to May 2021. Among 35 relevant articles, a total of 6 studies (10 data points) were finally selected, which enrolled 26,329 patients (26,219 breast cancer patients except hepatocellular carcinoma patients in 1 study), 4 cohort studies (8 data points) and 2 RCTs (2 data points). Among the 8 data points in cohort studies, four psychological stress-related factors (two 'anxiety', one 'depression', and one 'hostility') were shown to be moderately related with the risk for cancer recurrence, while 'loss of partner' resulted in opposite outcomes. The 'emotional' and 'mental' health factors showed conflicting results, and an RCT-derived meta-analysis proved the positive efficiency of psychotherapies in reducing the cancer recurrence risk among breast cancer patients (HR = 0.52; 95% CI 0.33-0.84). Despite the limitations, this study produces comprehensive information about the effect of psychological stress on cancer recurrence and provides reference data to clinicians and scientists for further studies.

Pilot testing an app-based stress management intervention for cancer survivors

Psychosocial eHealth intervention programs for cancer survivors are still in their infancy, with inconsistent findings so far in the scientific literature. The aim of this study was to explore system use, usefulness, ease of use, and preliminary effects of Stress Proffen, an app-based cognitive-behavioral stress management intervention for patients with cancer. A feasibility pilot project tested the intervention with cancer survivors (N = 25). The intervention contained (a) one face-to-face introduction session, (b) 10 app-based modules with stress management educational material and exercises, and (c) one follow-up phone call. Post-intervention interviews were conducted and user log-data were extracted. Outcome measures-Perceived Stress Scale (PSS), Anxiety and Depression (Hospital Anxiety and Depression Scale [HADS]), Health-Related Quality of Life (HRQoL; SF-36), and Self-Regulatory Fatigue (SRF-18)-were completed at baseline and post-intervention. Participants were primarily women (84%), age 34-71 (mean 48) and represented a variety of cancer diagnoses (majority breast cancer: 40%). Twenty-two participants completed all (pre-post) questionnaires. Sixteen participants (67%) completed at least 7 of 10 modules within the 8-week study period. Post-intervention interviews described StressProffen as providing a new, appreciated, and easily accessible stress management tool for the cancer survivors. Dependent/paired t-tests showed significant pre-post intervention effects with significant decrease in stress (p = .008), anxiety (p = .019), and self-regulatory fatigue (p = .025), and improved HRQoL (Role Physical, General Health, Vitality, and Role Emotional, all p's <.01). App-based stress management interventions such as StressProffen can provide appreciated support for cancer survivors, should be easy to use, can provide significant stress reduction, and improve emotional well-being. Further testing in a randomized controlled trial is warranted and is in progress. Clinicaltrials.gov: NCT0293961.

Effectiveness of Psychosocial Supportive Care Trial on Quality of Life among Breast Cancer Patients: An Interventional Study at the National Cancer Institute, Egypt

BACKGROUND: Breast cancer (BC) patients suffer from many psychosocial problems due to their health condition and treatment side effects so they are in great need for psychosocial supportive care. AIM: The aim of the study was to provide a comprehensive psych-social supportive health-care model for BC patients a step toward improving their quality of life (QOL). PATIENTS AND METHODS: Random assignment was done for 185 patients with primary operated BC to a control or an intervention group. The researcher offered five daily successive psychosocial supportive care sessions for the patients in the intervention group. All patients were followed up for coping ability, mood and QOL 8 weeks after the intervention. RESULTS: The intervention had statistically significant effects on psychological distress, depression, problem focused, and active emotional coping domain, while had not any statistically significant effects on avoidant emotional coping domain. CONCLUSION: Psychosocial supportive developed health-care model decreased psychological distress, depression, and improved QOL among patients with primary BC.

Effects of web-based cognitive behavioral stress management and health promotion interventions on neuroendocrine and inflammatory markers in men with advanced prostate cancer: A randomized controlled trial

Cognitive behavioral stress management (CBSM) improves quality of life and mitigates stress biology in patients with early-stage cancer, including men with localized prostate cancer. However, treatments for advanced prostate cancer like androgen deprivation therapy (ADT) can lead to significant symptom burden that may be further exacerbated by stress-induced inflammation and cortisol dysregulation. The aim of this study was to examine the effects of CBSM (versus an active health promotion control) on circulating inflammatory markers and cortisol in men with advanced prostate cancer.

METHODS

Men with stage III or IV prostate cancer (N = 192) who had undergone ADT within the last year were randomized to CBSM or health promotion. Both interventions were 10 weeks, group-based, and delivered online. Venous blood was drawn at baseline, 6 months, and 12 months to measure circulating levels of CRP, IL-6, IL-8, IL-10, and TNF-α. Saliva samples were collected at awakening, 30 min after awakening, evening, and night for two consecutive days at baseline, 6-months, and 12-months to measure diurnal cortisol slopes.

RESULTS

Mixed modeling analyses demonstrated that changes in inflammatory markers and cortisol did not differ by intervention. Men in both CBSM and health promotion showed decreases in IL-10, IL-8, and TNF-α from baseline to 6 months (β = -3.85--5.04, p's = 0.004-<0.001). However, these markers generally demonstrated a rebound increase from 6 to 12 months (β = 1.91-4.06, p's = 0.06-<0.001). Men in health promotion also demonstrated a flatter diurnal cortisol slope versus men in CBSM at 6 months (β = -2.27, p = .023), but not at 12 months. There were no intervention effects on CRP, IL-6, or overall cortisol output.

CONCLUSIONS

Contrary to hypotheses, CBSM did not lead to changes in the circulating inflammatory markers and cortisol relative to health promotion. CBSM may be associated with healthy diurnal cortisol rhythm because of its focus on cognitive behavioral approaches to stress management. More research is needed to understand the impact of CBSM and health promotion on biomarkers among men with advanced prostate cancer.

Development and evaluation of an internet-based cognitive behavioral therapy intervention for anxiety and depression in adults with cystic fibrosis (eHealth CF-CBT): An international collaboration

INTRODUCTION

Individuals with cystic fibrosis (CF) are at increased risk for anxiety and depression, with negative consequences for adherence, health, and quality of life. New approaches to prevent and treat anxiety and depression that are tailored to the concerns of this population are needed. A CF-specific internet-based cognitive-behavioral therapy (CBT) intervention was developed to increase access to evidence-based mental health care and decrease cost and burden of care for people with CF.

OBJECTIVE

To evaluate the usability and acceptability of "eHealth CF-CBT," an internet-based program integrating therapist-guided online self-management modules with in-person or virtual sessions.

METHODS

Dutch adults with CF (N = 16) and CF health care providers (N = 16) systematically tested all sessions of the eHealth CF-CBT program, provided qualitative feedback, and completed measures including eHealth Impact Questionnaire (eHIQ), and System Usability Scale (SUS).

RESULTS

Patient and provider ratings of their overall impression of the eHealth CF-CBT program were high, with scores (mean; SD) of 8.3; 0.6 and 8.2; 0.8 respectively on a 10-point scale. Mean ratings of usability by patients (77.0/100) and providers (73.4/100) surpassed the SUS cut point for good favorability. Ratings (pooled mean; SD) on the assessed eHIQ domains Motivation and Confidence to Act (71.3; 10.0), Information and Presentation (78.9; 9.6), and Identification (62.0; 15.1) were positive, as were assessments of specific elements of session content and format.

CONCLUSIONS

eHealth CF-CBT is the first therapist-guided internet-delivered CBT-based intervention for adults with CF. Initial evaluation with key stakeholders demonstrated high levels of acceptability and usability and provided input that was integrated to strengthen the program. Effectiveness testing in the Netherlands will be the next step, as well as future international adaptation and dissemination.

Toward improved in vitro models of human cancer

Cancer is a leading cause of death across the world and continues to increase in incidence. Despite years of research, multiple tumors (e.g., glioblastoma, pancreatic cancer) still have limited treatment options in the clinic. Additionally, the attrition rate and cost of drug development have continued to increase. This trend is partly explained by the poor predictive power of traditional in vitro tools and animal models. Moreover, multiple studies have highlighted that cell culture in traditional Petri dishes commonly fail to predict drug sensitivity. Conversely, animal models present differences in tumor biology compared with human pathologies, explaining why promising therapies tested in animal models often fail when tested in humans. The surging complexity of patient management with the advent of cancer vaccines, immunotherapy, and precision medicine demands more robust and patient-specific tools to better inform our understanding and treatment of human cancer. Advances in stem cell biology, microfluidics, and cell culture have led to the development of sophisticated bioengineered microscale organotypic models (BMOMs) that could fill this gap. In this Perspective, we discuss the advantages and limitations of patient-specific BMOMs to improve our understanding of cancer and how these tools can help to confer insight into predicting patient response to therapy.

A pilot study of mobilized intervention to help caregivers of oncology patients manage distress

OBJECTIVE

Caregivers of patients with advanced cancer experience significant anxiety, depression, and distress. Caregivers have barriers to accessing in-person treatment to manage stress. Technology allows for the dissemination of evidence-based interventions in a convenient way. This study examined usage rates of Pep-Pal (an evidence-based mobilized intervention to help caregivers of patients with advanced cancer manage distress) and estimates of efficacy on anxiety, depression, stress, and sexual dysfunction.

METHODS

Fifty-six primary caregivers of patients with advanced cancer were recruited through oncology clinics and randomized to either Pep-Pal (a mobilized psychoeducation and skills-based intervention for caregivers, n = 26) or treatment as usual (TAU; n = 30). All were screened for moderate anxiety on the Hospital Anxiety and Depression Scale-Anxiety screening assessment (A ≥ 8) at baseline.

RESULTS

Participants randomized to Pep-Pal experienced greater reductions in perceived stress (PSS; F = 3.91, p = .05), greater increases in ability to learn and use stress management skills (F = 6.16, p = 0.01), and greater increases in sexual function (women only; F = 5.07, p = 0.03) compared to participants in TAU. Of Pep-Pal participants, only 10 (38.5%) watched at least 7/9 full-length sessions. The a priori hypothesis and criterion that participants would watch at least 75% full-length sessions were not met.

CONCLUSIONS

A brief, easily disseminated mobile intervention showed poor adherence, but had limited estimates of efficacy for secondary outcomes; perceived stress, learning stress management skills, and sexual functioning (women only). Future directions are discussed.

The Effects of Cognitive-Behavioral Stress Management for Breast Cancer Patients: A Systematic Review and Meta-analysis of Randomized Controlled Trials

BACKGROUND

Treatment for breast cancer can be stressful for patients. Cognitive-behavioral stress management (CBSM) interventions aim to improve patients' skills in coping with stress and buffer against the negative effects of cancer.

OBJECTIVES

This meta-analysis aimed to demonstrate the impact of CBSM on breast cancer patients.

METHODS

We searched PubMed, EMBASE, the Cochrane Database, ScienceDirect, MEDLINE, CENTRAL, CINAHL, and PsycNET for randomized controlled trials (RCTs) published up to November 21, 2017. We then performed a meta-analysis of RCTs that compared CBSM for patients with breast cancer with a 1-day psychoeducation seminar, wait-list controls, or standard care.

RESULTS

Eighteen RCTs with 2564 participants were ultimately included. The results showed that CBSM can increase Measure of Current Status relaxation scores, benefit finding, and positive affect and decrease serum cortisol, anxiety, depression, thought avoidance and intrusion, and negative mood. However, it appears to have no effect on stress or mood disturbance.

CONCLUSIONS

Cognitive-behavioral stress management appears to be beneficial for breast cancer patients. Further high-quality RCTs are needed to clarify if any other factors are influenced by CBSM intervention.

IMPLICATIONS FOR PRACTICE

Cognitive-behavioral stress management can help breast cancer patients develop skills to increase relaxation, benefit finding, and positive affect; CBSM may provide a buffer against the negative effects of cancer. Further, CBSM may help breast cancer patients replace negative thoughts, improve their thought processes and behaviors, and maintain social support using cognitive and interpersonal coping skills. Nurses should be aware of the benefits of CBSM in their day-to-day care of breast cancer patients.

Stress and coping in women with breast cancer:unravelling the mechanisms to improve resilience

Breast cancer diagnosis, surgery, adjuvant therapies and survivorship can all be extremely stressful. In women, concerns about body image are common as a result of the disease and can affect interpersonal relationships, possibly leading to social isolation, increasing the likelihood for mood disorders. This is particularly relevant as women are at greater risk to develop anxiety and depressive symptoms in response to highly stressful situations. Here we address the mechanisms and the pathways activated as a result of stress and contributing to changes in the pathophysiology of breast cancer, as well as the potential of stress management factors and interventions in buffering the deleterious effects of chronic stress in a gender perspective. An improved understanding of the biological mechanisms linking stress-management resources to health-relevant biological processes in breast cancer patients could reveal novel therapeutic targets and help clarifying which psychosocial interventions can improve cancer outcomes, ultimately offering a unique opportunity to improve contemporary cancer treatments.

Psychosocial Interventions and Immune System Function: A Systematic Review and Meta-analysis of Randomized Clinical Trials

IMPORTANCE

Recent estimates suggest that more than 50% of all deaths worldwide are currently attributable to inflammation-related diseases. Psychosocial interventions may represent a potentially useful strategy for addressing this global public health problem, but which types of interventions reliably improve immune system function, under what conditions, and for whom are unknown.

OBJECTIVE

To address this issue, we conducted a systematic review and meta-analysis of randomized clinical trials (RCTs) in which we estimated associations between 8 different psychosocial interventions and 7 markers of immune system function, and examined 9 potential moderating factors.

DATA SOURCES

PubMed, Scopus, PsycInfo, and ClinicalTrials.gov databases were systematically searched from February 1, 2017, to December 31, 2018, for all relevant RCTs published through December 31, 2018.

STUDY SELECTION

Eligible RCTs included a psychosocial intervention, immune outcome, and preintervention and postintervention immunologic assessments. Studies were independently examined by 2 investigators. Of 4621 studies identified, 62 were eligible and 56 included.

DATA EXTRACTION AND SYNTHESIS

Data were extracted and analyzed from January 1, 2019, to July 29, 2019. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guideline was followed. Data were extracted by 2 investigators who were blind to study hypotheses and analyses, and were then analyzed using robust variance estimation. Analysis included 8 psychosocial interventions (behavior therapy, cognitive therapy, cognitive behavior therapy [CBT], CBT plus additive treatment or mode of delivery that augmented the CBT, bereavement or supportive therapy, multiple or combined interventions, other psychotherapy, and psychoeducation), 7 immune outcomes (proinflammatory cytokine or marker levels, anti-inflammatory cytokine levels, antibody levels, immune cell counts, natural killer cell activity, viral load, and other immune outcomes), and 9 moderating factors (intervention type, intervention format, intervention length, immune marker type, basal vs stimulated markers, immune marker measurement timing, disease state or reason for treatment, age, and sex).

MAIN OUTCOMES AND MEASURES

The primary a priori outcomes were pretest-posttest-control (ppc) group effect sizes (ppc g) for the 7 immunologic outcomes investigated.

RESULTS

Across 56 RCTs and 4060 participants, psychosocial interventions were associated with enhanced immune system function (ppc g = 0.30, 95% CI, 0.21-0.40; t50.9 = 6.22; P < .001). Overall, being randomly assigned to a psychosocial intervention condition vs a control condition was associated with a 14.7% (95% CI, 5.7%-23.8%) improvement in beneficial immune system function and an 18.0% (95% CI, 7.2%-28.8%) decrease in harmful immune system function over time. These associations persisted for at least 6 months following treatment and were robust across age, sex, and intervention duration. These associations were most reliable for CBT (ppc g = 0.33, 95% CI, 0.19-0.47; t27.2 = 4.82; P < .001) and multiple or combined interventions (ppc g = 0.52, 95% CI, 0.17-0.88; t5.7 = 3.63; P = .01), and for studies that assessed proinflammatory cytokines or markers (ppc g = 0.33, 95% CI, 0.19-0.48; t25.6 = 4.70; P < .001).

CONCLUSIONS AND RELEVANCE

These findings suggest that psychosocial interventions are reliably associated with enhanced immune system function and may therefore represent a viable strategy for improving immune-related health.

Technology-Based Psychosocial Intervention to Improve Quality of Life and Reduce Symptom Burden in Men with Advanced Prostate Cancer: Results from a Randomized Controlled Trial

BACKGROUND

Men with advanced prostate cancer (APC) face multiple challenges including poor prognosis, poor health-related quality of life (HRQOL), and elevated symptom burden. This study sought to establish the efficacy of a tablet-delivered, group-based psychosocial intervention for improving HRQOL and reducing symptom burden in men with APC. We hypothesized that men randomized to cognitive-behavioral stress management (CBSM) would report improved HRQOL and reduced symptom burden relative to men randomized to an active control health promotion (HP) condition. Condition effects on intervention targets and moderators of these effects were explored.

METHODS

Men with APC (N = 192) were randomized (1:1) to 10-week tablet-delivered CBSM or HP, and followed for 1 year. Multilevel modeling was used to evaluate condition effects over time.

RESULTS

Changes in HRQOL and symptom burden did not differ between groups. Men in both groups improved across several intervention targets; men in the CBSM condition reported greater increases in self-reported ability to relax, and both conditions showed improvements in cancer-related anxiety, cancer-related distress, and feelings of cohesiveness with other patients over time. Moderating factors included baseline interpersonal disruption, fatigue, and sexual functioning.

CONCLUSIONS

Tablet-delivered CBSM and HP were well received by men with APC. The hypothesized effects of CBSM on HRQOL and symptom burden were not supported, though improvements in intervention targets were observed across conditions. Participants reported high-baseline HRQOL relative to cancer and general population norms, possibly limiting intervention effects. The identified moderating factors should be considered in the development and implementation of interventions targeting HRQOL and symptom burden.

Yoga as a Therapy for Irritable Bowel Syndrome

The aim of this state-of-the-art narrative review is to evaluate the current evidence about the effectiveness of yoga as therapy for IBS and explore its potential mechanisms of action. The current literature suggests yoga is effective and safe and may target multiple mechanisms involved in treatment of IBS. Evidence from randomized controlled trials identified yoga as more effective compared to pharmacological treatment and equally effective as dietary interventions or moderate-intensity walking. Improvements were seen in both physical health (IBS symptom severity, gastric motility, autonomic and somatic symptom scores, and physical functioning) and mental health outcomes (depression, anxiety, gastrointestinal-specific anxiety, and quality of life). Given favorable changes in IBS-related physical and mental health outcomes, preliminary data supports yoga as beneficial in this population. However, the relatively low-quality evidence resulting from heterogeneity of study designs, interventions, and outcome measures limit our ability to make specific recommendations about the use of yoga as therapy for patients with IBS.

Adverse childhood experiences (ACEs), cell-mediated immunity, and survival in the context of cancer

PURPOSE

Adverse childhood experiences (ACEs) have been shown to be associated with increased risk of mortality. The biobehavioral mechanisms linking adverse events and survival in cancer patients remain unclear. The aims of the study were to: (1) examine the rates and types of early adverse events in patients diagnosed with cancer; (2) investigate the association of adverse events with circulating cytokines, representing immune status of the patient; and (3) test whether immune markers mediated the association between early adverse events and survival while adjusting for other factors that are associated with immunity (e.g., fatigue) and survival (e.g., depression).

PATIENTS AND METHODS

The patients were recruited from an outpatient oncology clinic. Patients were administered a battery of questionnaires including the Traumatic Events Survey and the Center for Epidemiological Studies-Depression scale. Blood was collected and serum levels of cytokines were assessed to characterize immune status. Descriptive statistics, Mann-Whitney U tests and Cox regression were performed to address study aims.

RESULTS

Of the 408 patients, 66% reported at least one ACE. After adjusting for demographic, disease-specific factors, and psychological/behavioral factors; having had a major upheaval between parents during childhood or adolescence was associated with poorer survival [β = -0.702, HR = 0.496, p = 0.034]. Lower levels of interleukin-2 (IL-2) explained, in part, the link between this early adverse event and poorer survival as when IL-2 was entered into the model, a major upheaval between one's parents and survival was no longer significant [β = -0.612, HR = 0.542, p = 0.104].

CONCLUSION

Having experienced an ACE was associated with lower IL-2 levels-a growth factor for anti-inflammatory T-regulatory lymphocytes-central in contemporary immunotherapy, as well as poorer survival in those diagnosed with cancer. Since lower IL-2 levels also explained, in part, the link between the ACE involving parental upheaval and survival, there is support for a psychoneuroimmunological model of disease course in this vulnerable population.

Preliminary study on the effects of treatment for breast cancer: immunological markers as they relate to quality of life and neuropsychological performance

BACKGROUND

Immunological biomarkers were related to quality of life and neuropsychological performance in women recently diagnosed with breast cancer through the first six months of treatment. A comparison group of breast cancer survivors in remission were also evaluated.

METHOD

Twenty women newly diagnosed with breast cancer and 26 breast cancer survivors at least a year after treatment were evaluated four times over a course of six to 8 months. The assessments included quality-of-life, emotional and spiritual well-being, sleep quality, computerized neuropsychological performance, and cytokine immunology biomarkers using flow cytometry. The principal immunological markers examined were the CD4+, CD8+, and CD16+ counts.

RESULTS

Although equivalent at enrollment, active treatment women reported higher anxiety, depression, poorer quality-of-life, and poorer processing speed and accuracy on memory, logical processes, and coding neuropsychological tasks. They also had significantly higher CD8+ and CD16+ cell count levels during treatment over the next six to eight months than comparison group women in remission. Women undergoing chemotherapy as well during treatment phase also had a significant decline in CD4+ counts. Higher percent CD8+ levels during treatment was associated with poorer quality of life and more depression, while higher CD4+ and CD8+ were associated with poorer neuropsychological memory and processing speed performance.

CONCLUSION

Significant increases in CD8+ is a sensitive biomarker of a broad range of poorer quality-of-life and neurocognitive functioning outcomes during breast cancer treatment, especially in women undergoing chemotherapy. Quality of life should be monitored in breast cancer patients and psychosocial support made available as a standard of care.

Effects of mindfulness-based cognitive therapy on breast cancer survivors with insomnia: A randomised controlled trial

OBJECTIVE

We investigated the effects of mindfulness-based cognitive therapy on insomnia (MBCT-I) in breast cancer survivors.

METHODS

In total, 136 participants were allocated randomly to a MBCT-I group or a waitlist control (WLC) group. Indicators of insomnia and mindfulness were evaluated using the Insomnia Severity Index, actigraphy and the Five Facet Mindfulness Questionnaire. Data were collected at baseline (T1), post-intervention (T2), 3-month follow-up (T3) and 6-month follow-up (T4) time points.

RESULTS

Insomnia severity decreased significantly in the MBCT-I group, compared with the WLC group, at T2, T3 and T4 (all p < .001). We found that 59.6% of the MBCT-I group with moderate and severe insomnia improved to no insomnia and subclinical insomnia at T4 relative to T1, accounting for 7.9% and 55.3%, respectively. Compared with the WLC group, the MBCT-I group improved on actigraphy measures of sleep; they exhibited a pattern of decreased sleep onset latency and waking after sleep onset, as well as increased total sleep time and sleep efficiency. Mindfulness also increased more in the MBCT-I group than in the WLC group at T2, T3 and T4 (all p < .001).

CONCLUSIONS

MBCT-I may be an efficacious non-pharmacologic intervention to improve sleep quality in breast cancer survivors.

A Pilot Randomized Trial Assessing the Effect of a Psychoeducational Intervention on Psychoneuroimmunological Parameters Among Patients With Nonmetastatic Breast Cancer

OBJECTIVE

The aim of this study was to determine a potential benefit of the specific psychoeducational intervention "Learning to Live with Cancer" (LTLWC) for patients with operated nonmetastatic breast cancer, with respect to psychological variables and endocrine and immune parameters.

METHODS

Fifty-two postmenopausal women with operated stage I to III breast cancer were randomized to either a breast cancer intervention group (BCIG, n = 30) who immediately began participating in the LTLWC intervention program or to a breast cancer control group (BCCG, n = 22). Matched healthy women were asked to participate as a noncancer comparison group (n = 26). All participants were evaluated at three different time points (t1-t3) using a set of standardized questionnaires and blood samples were taken to analyze immune cell subsets and stress hormone levels.

RESULTS

A significant reduction in trait anxiety/State Trait Anxiety Inventory score was observed in the BCIG (t1: median = 35.0 [interquartile range = 28.0-38.0] versus t3: median = 26.0 [interquartile range = 18.5-37.0], p = .0001) compared with the BCCG (t1: median = 41.0 [interquartile range =32.75-49.0]; t3: median = 38.5 [interquartile range = 30.75-46.5], p = .01524; p interaction = .001). In parallel, a significant rise of serotonin levels (t1: median = 66.5 ng/ml [interquartile range = 11.50-106.00] versus t3: median = 80.5 ng/ml [interquartile range =59.00-118.00], p = .00008) as well as a significant reduction of the elevated number of Treg cells at baseline (t1: median = 4.45% [interquartile range = 4.00-5.33] versus t3: median = 2.80% [interquartile range = 2.68-3.13], p < .00001) were observed in the BCIG versus no change in the BCCG. A significant statistical association between reduced trait anxiety and decreased Treg cell number could be demonstrated in the BCIG (r = .62, p < .01).

CONCLUSIONS

The observed results of this study provide preliminary support for the efficacy of the LTLWC program in significantly improving psychoneuroimmunological parameters in patients with nonmetastatic breast cancer.

Optimizing expectations about endocrine treatment for breast cancer: Results of the randomized controlled psy-breast trial

Background

Medication side effects are strongly determined by non-pharmacological, nocebo mechanisms, particularly patients’ expectations. Optimizing expectations could minimize side effect burden. This study evaluated whether brief psychological expectation management training (EXPECT) optimizes medication-related expectations in women starting adjuvant endocrine therapy (AET) for breast cancer.

Method

In a multisite randomized controlled design, 197 women were randomized to EXPECT, supportive therapy (SUPPORT), or treatment as usual (TAU). The three-session cognitive-behavioral EXPECT employs psychoeducation, guided imagery, and side effect management training. Outcomes were necessity-concern beliefs about AET, expected side effects, expected coping ability, treatment control expectations, and adherence intention.

Results

Both interventions were well accepted and feasible. Patients’ necessity-concern beliefs were optimized in EXPECT compared to both TAU and SUPPORT, d = .41, p < .001; d = .40, p < .001. Expected coping ability and treatment control expectations were optimized compared to TAU, d = .35, p = .02; d = .42, p < 001, but not to SUPPORT. Adherence intention was optimized compared to SUPPORT, d = .29, p = .02, but not to TAU. Expected side effects did not change significantly.

Conclusion

Expectation management effectively and partly specifically (compared to SUPPORT) modified medication-related expectations in women starting AET. Given the influence of expectations on long-term treatment outcome, psychological interventions like EXPECT might provide potential pathways to reduce side effect burden and improve quality of life during medication intake.

A Perspective on the Similarities and Differences Between Mindfulness and Relaxation

Mind-body medicine is an evidence-based approach to health and healing that focuses on interactions between the mind, body, and behavior. It encompasses a wide range of interventions that are similar yet different in meaningful ways. Mindfulness and relaxation practices are 2 mind-body techniques that have similarities and differences; however, these techniques are often used or discussed interchangeably, such that the differences between them become obscured. A greater understanding of the unique facets of mindfulness and relaxation is needed for researchers and clinicians to make informed decisions when selecting an approach. The purpose of the current article is to offer an evidence-informed perspective on similarities and differences between mindfulness and relaxation. Specifically, mindfulness and relaxation practices are compared and contrasted in terms of theoretical foundation, intention, and psychological and physiological effects and mechanisms. Implications for clinical practice and suggestions for future research are discussed.
