The prevalence and pharmacotherapy of depression in cancer patients

Assessment of psycho-oncology in the Middle East and North Africa region: a systematic review and meta-analysis

BACKGROUND

The Middle East and North Africa (MENA) region is expected to witness a significant increase in the burden of cancer. Contrary to Western literature, the burden of psycho-oncology is yet to be established within the MENA region. This study reviews all available evidence characterizing the psychological burden among patients with cancer across the MENA region.

METHODS

We systematically explored the PubMed/MEDLINE, Cochrane/CENTRAL, and Web of Science (WoS) databases for reports on the psychiatric burden among patients with cancer residing within the MENA region from January 2000 until January 2023. Raw proportion were extracted and analyzed using a random-effects model.

FINDINGS

Eighty-three studies comprised of 16 810 participants, representing 14 countries, met our inclusion criteria. Across the MENA region, the prevalence of depression, anxiety, and distress were 44% (95% CI, 39%-50%), 47% (95% CI, 40%-54%), and 43% (95% CI, 30%-56%), respectively. Prevalence of depression was significantly different across countries, with Palestine (73%; 95% CI, 42%-91%) reporting the highest rate while Morocco (23%; 95% CI, 7%-56%) reported the lowest. Similarly, anxiety significantly differed across MENA nations ranging from 64% (95% CI, 3%-99%) in Morocco to 28% (95% CI, 18%-42%) in Tunisia. Rates of depression and anxiety were significantly different across measurement tools but not between Arabic-speaking versus Persian/Farsi-speaking countries. Meta-regression models showed that neither publication year nor age affected the prevalence of both anxiety and depression (P = .374 and .091 for depression and P = .627, and .546 for anxiety, respectively).

INTERPRETATION

We report an abnormally high rate of psychiatric burden among patients with cancer in the MENA region. Thus, establishing appropriate psycho-oncologic interventions within the MENA region is of utmost importance.

Metabolic underpinnings of cancer-related fatigue

Cancer-related fatigue (CRF) is one of the most prevalent and detrimental complications of cancer. Emerging evidence suggests that obesity and insulin resistance are associated with CRF occurrence and severity in cancer patients and survivors. In this narrative review, we analyzed recent studies including both preclinical and clinical research on the relationship between obesity and/or insulin resistance and CRF. We also describe potential mechanisms for these relationships, though with the caveat that because the mechanisms underlying CRF are incompletely understood, the mechanisms mediating the association between obesity/insulin resistance and CRF are similarly incompletely delineated. The data suggest that, in addition to their effects to worsen CRF by directly promoting tumor growth and metastasis, obesity and insulin resistance may also contribute to CRF by inducing chronic inflammation, neuroendocrinological disturbance, and metabolic alterations. Furthermore, studies suggest that patients with obesity and insulin resistance experience more cancer-induced pain and are at more risk of emotional and behavioral disruptions correlated with CRF. However, other studies implied a potentially paradoxical impact of obesity and insulin resistance to reduce CRF symptoms. Despite the need for further investigation utilizing interventions to directly elucidate the mechanisms of cancer-related fatigue, current evidence demonstrates a correlation between obesity and/or insulin resistance and CRF, and suggests potential therapeutics for CRF by targeting obesity and/or obesity-related mediators.

Classification of high-risk depressed mood groups in cancer patients based on Health Ecology Model

BACKGROUND

Depressed mood affects a significant number of patients with cancer, and can impair their quality of life and interfere with successful treatment. Our study aims to create a predictive model for identifying high-risk groups of depressed mood in cancer patients, offering a theoretical support for preventing depressed mood in these individuals.

METHODS

The China Health and Retirement Longitudinal Study (CHARLS) provided the data for this research, which used CES-D as a tool to identify individuals with depressed mood. Influencing factors of depressed mood in cancer patients was analyzed using a binary logistic regression model. Using the Harvard Cancer Index, we classified the high-risk patients for depressed mood.

RESULTS

In present study, 52.96 % of cancer patients met criteria for depressed mood based on the CES-D. Significant correlations were found between depressed mood and factors such as gender, self-rated health, sleep duration, exercise, satisfaction with family, residence, education, life satisfaction, and medical insurance. Utilizing the Harvard Cancer Index, we classified patients into five risk levels for depressed mood, revealing a significant variation in the number of depressive patients across these levels (x2=99.82, P < 0.05). Notably, the incidence of depressed mood increased with the risk level among cancer patients (x2=103.40, P < 0.05).

LIMITATIONS

Lack of data on tumor typing and subgroups makes it unlikely to explore the specifics of depressed mood in patients with various types of cancer.

CONCLUSION

The determinants of depressed mood in cancer patients are multi-dimensional. The Harvard Cancer Index may be helpful in identifying high-risk populations.

Pandemic-Induced Depression Among Older Adults with a History of Cancer During the COVID-19 Pandemic: Findings from the Canadian Longitudinal Study on Aging

Purpose

The objectives of this study were to identify the prevalence of, and factors associated with, incident and recurrent depression in a sample of older adults with a history of cancer during the COVID-19 pandemic.

Materials and Methods

Data were drawn from four waves of the Canadian Longitudinal Study on Aging Comprehensive Cohort (n=2486 with cancer). The outcome of interest was a positive screen for depression based on the CES-D-10 during the autumn of 2020.

Results

Among older adults with cancer and no pre-pandemic history of depression (n=1765), 1 in 8 developed first onset depression during the pandemic. Among respondents with cancer and a history of depression (n=721), 1 in 2 experienced a recurrence of depression. The risk of both incident and recurrent depression was higher among those who were lonely, those with functional limitations, and those who experienced an increase in family conflict during the pandemic. The risk of incident depression only was higher among older women, those who did not engage in church or religious activities, those who experienced a loss of income during the pandemic, and those who became ill or had a loved one become ill or die during the pandemic. The risk of recurrent depression only was higher among those who felt isolated from others and those whose income did not satisfy their basic needs.

Conclusion

Health care providers should continue to screen and provide mental health support to their cancer patients and those with a lifetime history of cancer, with consideration for those with the aforementioned vulnerabilities.

Association between Chinese herbal medicine (CHM) treatment and depression among cancer patients in China: An outpatient-based cross-sectional study

Depression is a prevalent condition among cancer patients and significantly impacts their quality of life. Traditional Chinese Medicine, particularly Chinese Herbal Medicine (CHM), has shown potential in both anti-tumor and anti-depressive effects. However, there is a dearth of scientific literature exploring the association between CHM treatment and depression in cancer patients. This study aims to investigate the relationship between CHM treatment and depression in cancer patients. A cross-sectional study was conducted among cancer outpatients at Longhua Hosiptal, Shanghai University of Traditional Chinese Medicine, from June 2020 to April 2021 (Ethical approval number: 2020LCSY057). All patients signed informed consent and completed The European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (EORTC QLQ-C30). Hamilton depression scale was evaluated depression by psychiatrists. The power of the sample size was determined using Gpower statistical and SPSS were used for statistical analysis. A total of 809 completed the study. Gender, medical insurance, the classification of time since diagnosis, ECOG, cancer stage, metastasis, gene mutation, treatment plan and CHM treatment were an important factor affecting depression (P < .05). Further analysis investigated the impact of CHM treatment on depression. There were 374 enrolled in CHM group and 435 enrolled in Non-CHM group. The assessment results of Hamilton depression scale and EORTC QLQ-C30 in CHM group were superior to those in Non-CHM group. The morbidity of depression is 50.27% in CHM group and 66.44% in Non-CHM group. After adjusting for potential confounders (gender, medical insurance, cancer stage, etc.), CHM treatment indicated negative correlation with depression (Odds ratio (OR) = 0.7, 95% confidence interval (CI): 0.5-0.9, P = .020). The interaction effects within each subgroup were no significantly affect the relationship between CHM treatment and depression (P > .05). CHM treatment was an independent protective factor for depression in cancer patients, and lead to better quality of life for cancer patients.

Effectiveness and implementation of an electronic health record-integrated digital health intervention for managing depressive symptoms in ambulatory oncology: The My Well-Being Guide study rationale and protocol

BACKGROUND

Rates of clinically elevated depressive symptoms among ambulatory oncology patients are higher than in the general population and are associated with poorer health-related quality of life. Furthermore, a reduction in depressive symptoms may be associated with improved cancer survival. Several interventions have demonstrated efficacy in reducing oncologic depressive symptoms, including cognitive-behavioral stress management (CBSM). However, more work is needed to understand how to best implement CBSM into practice, such as through stepped-care approaches and digital health interventions linked to electronic health records (EHR). This manuscript presents the protocol of the My Well-Being Guide study, a pragmatic type 1 effectiveness-implementation hybrid study. This trial will test the effectiveness of My Well-Being Guide, a seven-week structured, CBSM-based digital health intervention designed to reduce depressive symptoms. This trial will also evaluate My Well-Being Guide's implementation across two health systems.

METHODS

The final sample (N = 4561) will be oncology patients at Northwestern Medicine or University of Miami Health System who are ≥18 years of age; have a cancer diagnosis; elevated depressive symptoms on the Patient-Reported Outcomes Measurement Information System Depression; and primary language is English or Spanish. Data collection will occur at baseline, and 2-, 6-, and 12-months post baseline. Outcome domains include depressive symptoms and implementation evaluation.

DISCUSSION

This study may provide valuable data on the effectiveness of our depressive symptom management digital health intervention linked to the EHR and the scalability of digital health interventions in general.

Antidepressants for the treatment of depression in people with cancer

BACKGROUND

Major depression and other depressive conditions are common in people with cancer. These conditions are not easily detectable in clinical practice, due to the overlap between medical and psychiatric symptoms, as described by diagnostic manuals such as the Diagnostic and Statistical Manual of Mental Disorders (DSM) and International Classification of Diseases (ICD). Moreover, it is particularly challenging to distinguish between pathological and normal reactions to such a severe illness. Depressive symptoms, even in subthreshold manifestations, have a negative impact in terms of quality of life, compliance with anticancer treatment, suicide risk and possibly the mortality rate for the cancer itself. Randomised controlled trials (RCTs) on the efficacy, tolerability and acceptability of antidepressants in this population are few and often report conflicting results.

OBJECTIVES

To evaluate the efficacy, tolerability and acceptability of antidepressants for treating depressive symptoms in adults (aged 18 years or older) with cancer (any site and stage).

SEARCH METHODS

We used standard, extensive Cochrane search methods. The latest search date was November 2022.

SELECTION CRITERIA

We included RCTs comparing antidepressants versus placebo, or antidepressants versus other antidepressants, in adults (aged 18 years or above) with any primary diagnosis of cancer and depression (including major depressive disorder, adjustment disorder, dysthymic disorder or depressive symptoms in the absence of a formal diagnosis).

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. Our primary outcome was 1. efficacy as a continuous outcome. Our secondary outcomes were 2. efficacy as a dichotomous outcome, 3. Social adjustment, 4. health-related quality of life and 5. dropouts. We used GRADE to assess certainty of evidence for each outcome.

MAIN RESULTS

We identified 14 studies (1364 participants), 10 of which contributed to the meta-analysis for the primary outcome. Six of these compared antidepressants and placebo, three compared two antidepressants, and one three-armed study compared two antidepressants and placebo. In this update, we included four additional studies, three of which contributed data for the primary outcome. For acute-phase treatment response (six to 12 weeks), antidepressants may reduce depressive symptoms when compared with placebo, even though the evidence is very uncertain. This was true when depressive symptoms were measured as a continuous outcome (standardised mean difference (SMD) -0.52, 95% confidence interval (CI) -0.92 to -0.12; 7 studies, 511 participants; very low-certainty evidence) and when measured as a proportion of people who had depression at the end of the study (risk ratio (RR) 0.74, 95% CI 0.57 to 0.96; 5 studies, 662 participants; very low-certainty evidence). No studies reported data on follow-up response (more than 12 weeks). In head-to-head comparisons, we retrieved data for selective serotonin reuptake inhibitors (SSRIs) versus tricyclic antidepressants (TCAs) and for mirtazapine versus TCAs. There was no difference between the various classes of antidepressants (continuous outcome: SSRI versus TCA: SMD -0.08, 95% CI -0.34 to 0.18; 3 studies, 237 participants; very low-certainty evidence; mirtazapine versus TCA: SMD -4.80, 95% CI -9.70 to 0.10; 1 study, 25 participants). There was a potential beneficial effect of antidepressants versus placebo for the secondary efficacy outcomes (continuous outcome, response at one to four weeks; very low-certainty evidence). There were no differences for these outcomes when comparing two different classes of antidepressants, even though the evidence was very uncertain. In terms of dropouts due to any cause, we found no difference between antidepressants compared with placebo (RR 0.85, 95% CI 0.52 to 1.38; 9 studies, 889 participants; very low-certainty evidence), and between SSRIs and TCAs (RR 0.83, 95% CI 0.53 to 1.22; 3 studies, 237 participants). We downgraded the certainty of the evidence because of the heterogeneous quality of the studies, imprecision arising from small sample sizes and wide CIs, and inconsistency due to statistical or clinical heterogeneity.

AUTHORS' CONCLUSIONS

Despite the impact of depression on people with cancer, the available studies were few and of low quality. This review found a potential beneficial effect of antidepressants against placebo in depressed participants with cancer. However, the certainty of evidence is very low and, on the basis of these results, it is difficult to draw clear implications for practice. The use of antidepressants in people with cancer should be considered on an individual basis and, considering the lack of head-to-head data, the choice of which drug to prescribe may be based on the data on antidepressant efficacy in the general population of people with major depression, also taking into account that data on people with other serious medical conditions suggest a positive safety profile for the SSRIs. Furthermore, this update shows that the usage of the newly US Food and Drug Administration-approved antidepressant esketamine in its intravenous formulation might represent a potential treatment for this specific population of people, since it can be used both as an anaesthetic and an antidepressant. However, data are too inconclusive and further studies are needed. We conclude that to better inform clinical practice, there is an urgent need for large, simple, randomised, pragmatic trials comparing commonly used antidepressants versus placebo in people with cancer who have depressive symptoms, with or without a formal diagnosis of a depressive disorder.

Development of an evidence‑based, theory‑driven, and culturally appropriate character strengths-based intervention for breast cancer patients, following the Medical Research Council Framework

PURPOSE

To design and develop a complex, evidence‑based, theory‑driven, and culturally appropriate character strengths-based intervention (CSI) for breast cancer patients, following the Medical Research Council (MRC) framework.

METHODS

From 2018 September to 2020 November, a complex intervention perspective was adopted. The rationale, methods, and processes employed in carrying out the study were reported. The acceptability and feasibility of intervention program were evaluated as a part of subsequent pilot study. Based on piloting, a refined and optimized definitive intervention was obtained. The development of the intervention is an iterative process involving input from three key stakeholders: experts, medical staff, and patient representatives.

RESULTS

The systematic review revealed CSIs were effective and the selected theory served as a guide and indicated theory-inspired modifications. A representative team of breast cancer patients and oncology nurses collaboratively developed and tailored the intervention content and format with attention to the acceptability and feasibility. Five main strategies, including peripheral, evidential, linguistic, constituent-involving, and sociocultural strategies, were used to achieve and strengthen the cultural appropriateness. After the pilot phase, several refinements were made on the CSI program, such as editorial changes in the booklet or alternative suggestions for difficult strengths-based activities (e.g., outdoor activities). All participants not only expressed satisfaction with the program in process evaluation, but also reported perceived benefits such as enjoyable and sociable experience, better well-being, and increased confidence.

CONCLUSION

Consideration of the MRC framework, theory guidance, and suggestions from stakeholders during intervention development can optimize uptake and sustainability in the clinical setting. It is recommended that randomized controlled trial be used in future studies to assess the intervention, the process and the mechanisms of the intervention. Our approach may offer implications for the design and implementation of similar initiatives to support cancer patients.

Androgen deprivation therapy and depression in the prostate cancer patients: review of risk and pharmacological management

Purpose: Despite the effectiveness of androgen deprivation therapy in advanced prostate cancer, serious neuropsychiatric consequences in androgen deprivation therapy (ADT)-treated patients, mainly depression, have been concerning and gained more attention recently. This narrative review aims to shed light on the risk and pharmacological management of ADT-induced depression in PCa patients.Methods: We searched PubMed, Scopus and Google Scholar databases using MESH keywords "Prostate cancer OR prostate neoplasm" AND "Depression" AND "Androgen Deprivation Therapy" AND "antidepressants". Search was limited to English and studies conducted on humans. Studies' titles and abstracts were screened, and further information were obtained from the text, if necessary, to decide whether studies are to be included in this review.Results: Our review revealed 23 studies confirming the occurrence and worsening of depressive symptoms in ADT-treated patients, which frequently require pharmacological interventions; whereas 10 studies indicated otherwise. All studies were prospective, retrospective, cross-sectional or case reports. Based on the incidence of depression provided by the observational studies, the average among ADT-treated patients was 18.23% (range: 2.1-46.9%), while it was 8.42% (range: 1.4-23.3%) in the non-ADT patients. Although several treatments have been used for depression in cancer patients, current knowledge lacks observational and controlled studies as well as clinical guidelines that demonstrate efficacy and safety of antidepressants and guide clinicians to the appropriate treatment in these patients, respectively. On the other side, a few clinical studies have been published regarding the efficacy of selective serotonin reuptake inhibitors, selective serotonin and norepinephrine reuptake inhibitors and/or saftey on other ADT associated adverse effects.Conclusions: Our work supports the recent attention towards mood issues as an adverse effect of ADT, and that greater awareness of this is warranted among clinicians. Clinical studies published regarding the use of antidepressants for other ADT associated adverse effects established the foundation that can be adopted to examine these therapies on ADT-induced depression.

Is depression the missing link between inflammatory mediators and cancer?

Patients with cancer are at greater risk of developing depression in comparison to the general population and this is associated with serious adverse effects, such as poorer quality of life, worse prognosis and higher mortality. Although the relationship between depression and cancer is now well established, a common underlying pathophysiological mechanism between the two conditions is yet to be elucidated. Existing theories of depression, based on monoamine neurotransmitter system dysfunction, are insufficient as explanations of the disorder. Recent advances have implicated neuroinflammatory mechanisms in the etiology of depression and it has been demonstrated that inflammation at a peripheral level may be mirrored centrally in astrocytes and microglia serving to promote chronic levels of inflammation in the brain. Three major routes to depression in cancer in which proinflammatory mediators are implicated, seem likely. Activation of the kynurenine pathway involving cytokines, increases tryptophan catabolism, resulting in diminished levels of serotonin which is widely acknowledged as being the hallmark of depression. It also results in neurotoxic effects on brain regions thought to be involved in the evolution of major depression. Proinflammatory mediators also play a crucial role in impairing regulatory glucocorticoid mediated feedback of the hypothalamic-pituitary-adrenal axis, which is activated by stress and considered to be involved in both depression and cancer. The third route is via the glutamatergic pathway, whereby glutamate excitotoxicity may lead to depression associated with cancer. A better understanding of the mechanisms underlying these dysregulated and other newly emerging pathways may provide a rationale for therapeutic targeting, serving to improve the care of cancer patients.

Prevalence of anxiety and depression in people with different types of cancer or haematologic malignancies: a cross-sectional study

AIMS

Cancer patients often present with psychological symptoms that affect their quality of life, physical health outcomes and survival. Two of the most frequent psychiatric comorbidities are anxiety and depression. However, the prevalence of these disorders among cancer patients remains unclear, as studies frequently report varying rates. In the present study, we aimed to provide robust point estimates for the prevalence of anxiety and depression for both a mixed cancer sample and for 13 cancer types separately, considering confounding variables.

METHODS

In a sample of 7509 cancer outpatients (51.4% female), we used the Hospital Anxiety and Depression Scale to assess rates of anxiety and depression. Applying ordinal logistic regression models, we compared the prevalence of anxiety and depression between different cancer types, controlling for age and gender.

RESULTS

About one third of our sample showed symptoms of anxiety (35.2%) or depression (27.9%), and every sixth patient had a very likely psychiatric condition, with women being more frequently affected. Elderly patients more often showed signs of depression. The prevalence of anxiety and depression was significantly higher in lung and brain cancer patients, than in other cancer patients. Lowest depression rates were found in breast cancer patients.

CONCLUSIONS

The prevalence of anxiety and depression is high in cancer patients. Type of cancer is an important predictor for anxiety and depressive symptoms, with lung and brain cancer patients being highly burdened. Considering a personalised medicine approach, physicians should take into account the high prevalence of psychiatric comorbidities and include psychiatric consultations in the treatment plan.

Prevalence of depression and associated factors among adult cancer patients receiving chemotherapy during the era of COVID-19 in Ethiopia. Hospital-based cross-sectional study

Background

Depression is a major public health problem among cancer patients undergoing chemotherapy. It compromises patient outcomes, resulting in higher rates of mortality. Currently, there are little data on the prevalence of depression in Sub-Sharan countries. Therefore, the current study was done to assess the prevalence of depression among adult cancer patients and its associated factors in Ethiopia.

Method

An institutional based cross-sectional study was conducted among 420 adult cancer patients from 1^st March to April 30, 2021. Systematic random sampling technique was used to recruit participants. Depression was assessed using the Patient Health Questionnaire-9. The collected data were coded and entered into Epi-data version 4.2 and exported to SPSS version 25 for analysis. Bivariate binary logistic regression was performed to select factors that will be included in multivariate analysis, and variables with a p-value < 0.05 were included in multivariate analysis. In multivariate analysis, odds ratios and their 95% confidence intervals were computed and variables with p-value < 0.05 were considered to declare a significant association.

Results

In this study, the prevalence of depression was 33.1% (95% CI = 0.2858, 0.3761). Minimal symptoms of depression, minor depression, moderate depression, moderate severe depression, and severe depression were found to be 272 (64.8%), 9 (2.1%), 104 (24.8%), 28 (6.7%), and 7 (1.7%), respectively. Those cancer patients who had unemployed status, sacked from jobs, and had stage IV cancer were most likely to develop depression, whereas patients who completed primary education, colon, prostate and cervical cancer were less likely to have depression.

Conclusion

Depression is found to be a major public health concern for adult cancer patients in Ethiopia. To reduce the occurrence of depression among cancer patients, special attention is needed.

Mental health among patients with non-Hodgkin lymphoma: A Danish nationwide study of psychotropic drug use in 8750 patients and 43 750 matched comparators

Psychological distress following cancer diagnosis may lead to mental health complications including depression and anxiety. Non-Hodgkin lymphomas (NHLs) include indolent and aggressive subtypes for which treatment and prognosis differ widely. Incident use of psychotropic drugs (PDs-antidepressants, antipsychotics, and anxiolytics) and its correlation to lymphoma types can give insights into the psychological distress these patients endure. In this prospective matched cohort study, we used nationwide population-based registries to investigate the cumulative risk of PD use in NHL patients compared to a sex- and age-matched cohort from the Danish background population. In addition, contact patterns to psychiatric departments and incident intentional self-harm or completed suicide were explored. In total, 8750 NHL patients and 43 750 matched comparators were included (median age 68; male:female ratio 1.6). Median follow-up was 7.1 years. Two-year cumulative risk of PD use was higher in NHL patients (16.4%) as compared to the matched comparators (5.1%, p < .01); patients with aggressive NHL subtypes had the highest incidence. Prescription rates were higher in the first years after diagnosis but approached the rate of the matched population 5 years into survivorship in aggressive NHLs, whereas patients with indolent subtypes continued to be at higher risk. NHL patients had a slightly higher two-year risk of suicide/intentional self-harm (0.3%) as compared to the matched comparators (0.2%, p = .01). These results demonstrate that mental health complications among NHL patients are frequent. Routine assessment for symptoms of depression and anxiety should be consider as part of standard follow-up of NHL patients.

Psychological disorders in patients with orthopaedic oncological diseases and their coping strategies

BACKGROUND

This study aimed to determine the prevalence and risk factors of anxiety and depression among orthopaedic oncology patients, their quality of life and coping strategies.

METHODS

This cross-sectional study recruited patients from the outpatient orthopaedic oncology clinic at a tertiary institution. Data were collected from self-report questionnaires: Hospital Anxiety and Depression Scale Hospital Anxiety Depression Scale, World Health Organization Quality of Life (WHOQOL-BREF) and Brief Coping with Problems Experienced (Brief COPE). Risk factors were analyzed with multiple logistic regression.

RESULTS

191 patients were recruited. The median age was 39.4 years old (IQR 35.0). 29.8% had anxiety, 16.2% had depression, and 15.2% had mixed anxiety and depression. Quality of life median scores differed significantly between patients with anxiety and no anxiety and patients with depression and no depression (p < 0.001). Patients with mixed anxiety and depression had a more inferior quality of life (p < 0.001). Age, psychological health and radiotherapy were inversely associated with anxiety. Physical and psychological health were significantly associated with less depression. Ongoing chemotherapy was significantly associated with anxiety and depression. The commonest coping strategies were denial, behavioural disengagement, venting and self-blame.

CONCLUSION

Anxiety and depression are prevalent among orthopaedic oncology patients. Patients with mixed anxiety and depression had a more inferior quality of life. Patients with ongoing chemotherapy had higher risks of anxiety and depression. The commonest coping strategies were denial, behavioural disengagement, venting and self-blame. Psychosocial evaluation followed by appropriate psychiatric referrals and consultations could be established to facilitate orthopaedic oncology patients during their course of treatment.

Palliative Care for Patients With Cancer and Kidney Disease

Patients with cancer and kidney disease experience a range of symptoms that impact their quality of life. Pain, fatigue, decreased appetite, and depression are all common in this population. Kidney palliative care is patient-centered medical care focused on reducing symptoms and defining individualized goals of care for patients and their families. Pharmacologic management of pain in patients with cancer and kidney disease requires recognition of the type of pain, its cause, and the risks and benefits of different medication classes. This review describes basic symptom management options as well as considerations for discussing goals of care, prognosis, and end of life.

Psychotropic Drug Use in Acute Myeloid Leukaemia (AML) and Myelodysplastic Syndrome (MDS): A Danish Nationwide Matched Cohort Study of 2404 AML and 1307 MDS Patients

Introduction

The diagnosis of a life-threatening disease can lead to depression and anxiety resulting in pharmacological treatment. However, use of psychotropic drugs (antidepressants, anxiolytics, and antipsychotics) in acute myeloid leukaemia (AML) and myelodysplastic syndrome (MDS) is undetermined.

Methods

Prescription of psychotropic drugs in Danish AML and MDS patients was compared to a cohort matched on age, sex, and country of origin from the Danish background population using national population-based registries.

Results

In total, 2404 AML patients (median age 69 years) and 1307 MDS patients (median age 75 years) were included and each matched to five comparators from the background population. Two-year cumulative incidences showed that AML (20.6%) and MDS (21.2%) patients had a high risk of redemption of a psychotropic drug prescription compared to the background population (7.0% and 7.9%). High age, low educational level, and Charlson Comorbidity Index score ≥1 was associated with a higher risk in AML and MDS patients. Furthermore, non-curative treatment intent and performance status in AML patients, and high risk MDS were associated with elevated risk of psychotropic drug prescription.

Conclusion

In conclusion, diagnoses of AML and MDS were associated with a higher rate of psychotropic drugs prescription compared to the background population.

Addressing distress management challenges: Recommendations from the consensus panel of the American Psychosocial Oncology Society and the Association of Oncology Social Work

Distress management (DM) (screening and response) is an essential component of cancer care across the treatment trajectory. Effective DM has many benefits, including improving patients' quality of life; reducing distress, anxiety, and depression; contributing to medical cost offsets; and reducing emergency department visits and hospitalizations. Unfortunately, many distressed patients do not receive needed services. There are several multilevel barriers that represent key challenges to DM and affect its implementation. The Consolidated Framework for Implementation Research was used as an organizational structure to outline the barriers and facilitators to implementation of DM, including: 1) individual characteristics (individual patient characteristics with a focus on groups who may face unique barriers to distress screening and linkage to services), 2) intervention (unique aspects of DM intervention, including specific challenges in screening and psychosocial intervention, with recommendations for resolving these challenges), 3) processes for implementation of DM (modality and timing of screening, the challenge of triage for urgent needs, and incorporation of patient-reported outcomes and quality measures), 4) organization-inner setting (the context of the clinic, hospital, or health care system); and 5) organization-outer setting (including reimbursement strategies and health-care policy). Specific recommendations for evidence-based strategies and interventions for each of the domains of the Consolidated Framework for Implementation Research are also included to address barriers and challenges.

Fatigue and its management in cancer patients undergoing VEGFR-TKI therapy

INTRODUCTION

Fatigue is the most common side effect of cancer and cancer treatment and is often called cancer fatigue or cancer-related fatigue. For cancer patients, cancer-related fatigue has a negative impact on participation in work and social activities, mood, and daily activities, significantly impairing quality of life. Vascular endothelial growth factor receptor tyrosine kinase inhibitors (VEGFR-TKIs) sometimes cause fatigue, and early detection and appropriate management of fatigue in cancer patients treated with a VEGFR-TKI prevent fatigue from becoming more severe, thus maximizing the benefits of the treatment.

AREAS COVERED

This paper focuses on fatigue and discusses its frequency, assessment, risk factors, and management methods.

EXPERT OPINION

The drugs currently available for treating cancer-related fatigue are not effective enough, and their mechanisms of action are not fully understood. Some agents have demonstrated efficacy as treatments for fatigue due to pharmacotherapy, and further elucidation of their mechanisms is expected, together with the development of new drugs. Since fatigue has a range of causes, its treatment requires not only medication, but also exercise, nutrition, and other therapeutic approaches. The successful treatment of fatigue will therefore need multidisciplinary therapy involving the establishment of systems of cooperation across various specialties.

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

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

Improving access to cancer information and supportive care services: A systematic review of mechanisms applied to link people with cancer to psychosocial supportive care services

OBJECTIVE

Previous research has described the low uptake of psychosocial support services in people living with cancer. While characteristics of individuals using services have been examined, mechanisms applied to link individuals to support services are less frequently considered. This review aims to identify the mechanisms used to link people with cancer to support services and assess their impact.

METHODS

Systematic searches of Pubmed, CINAHL, EMBASE and PsycINFO were conducted up to May 2020. Studies reporting service use associated with mechanisms to link adults with cancer to support services targeting emotional, informational, practical or social support needs were eligible. Eligible study designs included controlled trials, pre-post designs and observational studies. Study quality was assessed and a narrative synthesis of findings undertaken.

RESULTS

A total of 10 papers (from 8,037 unique titles) were eligible. Testing the feasibility of the linkage mechanism was the primary aim in five (50%) studies. Three linkage mechanisms were identified: (a) outreach from the support service; (b) clinician recommendation/referral; (c) mailed invitation. Outreach was the most successful in connecting people with cancer to services (52%-90% use); clinician recommendation/referral was least successful (3%-28%). The impact of different linkage mechanisms for different demographic groups was not assessed.

CONCLUSIONS

Outreach from services shows the most potential for increasing access to support services. However, the limited number of studies and limitations in the types of support services people with cancer were linked to, demonstrated the need for further work in this area. Identifying mechanisms that are effective for underserved, high-needs patient groups is also needed.

Patient reported outcomes affecting quality of life in socioeconomically disadvantaged cancer patients

PURPOSE

The aim of this study was to identify correlates of quality of life (QOL) for socioeconomically disadvantaged cancer patients receiving care in the "safety net" health system.

DESIGN

This cross-sectional study used linear regressions to determine the effect of patient reported outcome measures (PRO) on QOL.Sample/Methods: Cancer patients (n = 115) receiving drug therapy completed a series of PROs including: Functional Assessment of Cancer Therapy (FACT-G), PROMIS (Anxiety, Depression, Fatigue, Pain Interference, and Physical Function), and the Comprehensive Score for Financial Toxicity.

FINDINGS

More than 60% of patients reported an annual income below $24,999. Forty-five percent of patients were either uninsured or county-funded. Depression, pain, and financial toxicity were found to be consistently significant correlates of QOL.Implications: Cancer patients with existing financial strain have unique psychosocial stressors. This study provides insight into the relationship between these stressors, and the need for targeted screening and intervention that address such aspects of care.

Pathophysiological implications of neuroinflammation mediated HPA axis dysregulation in the prognosis of cancer and depression

Cancer patients are more likely to develop depressive symptoms and show a poor prognosis compared to the normal healthy individuals. Cancer occurrence and the anticancer treatments result in the pro-inflammatory cytokines-mediated inflammation, which dysregulates the HPA-axis activity that may result in depression-like behaviour. Conversely, depression causes the activation of the HPA-axis that results in the downstream release of endogenous glucocorticoids which may result in depressive signs and symptoms in some cancer patients. Depression may also result in non-adherence to treatment and increased mortality in cancer patients. In this review, we have focused on the role of neuroimmune axis and hyperactive HPA-axis in case of both cancer and depression. Therefore, therapeutics targeting the HPA-axis dysregulation could be effective in ameliorating symptoms of depression in cancer patients.

Depression treatment research in people with cancer does not reflect cancer prevalence: findings from a systematic review

BACKGROUND

One in six people with cancer will develop depression at some point in their care. Untreated depression affects quality of life, cancer care satisfaction and healthcare expenditure. Treatments for this vulnerable heterogenous population should be evidence based and specific. A common sentiment is that psychiatric research does not reflect the prevalence of patients with cancer and comorbid depression and is biased towards certain cancers, but this has not been empirically shown.

STUDY SELECTION AND ANALYSIS

A systematic review of studies on psychological and pharmacological treatments for depression in people with cancer was conducted. Of 4621 papers identified from a search of PubMed and PsycINFO up to 27 June 2020, 84 met inclusion criteria (eg, adults with cancer; depression diagnosis; treatment study) and comprised 6048 participants with depression with cancer.

FINDINGS

Cancer types are not proportionally represented in depression research in accordance with their incidence. Breast cancer is over-represented (relative frequency in research 49.3%, but 11.7% of global cancer). Cancers of the head and neck and bone and soft tissue were close to parity. All other cancers are under-represented. Representativeness varied 40-fold across different cancers.

CONCLUSIONS

The evidence base for depression treatments is dominated by a single cancer. Given heterogeneity in cancer populations (eg, stage of illness; psychological impact; cancer treatments), it is possible that depression treatments may not have the same benefits and harms across all cancers, impeding the ability to offer people with different cancers the best depression treatment. While the dominant opinion within this research field is that a cancer bias exists, this is the first study to demonstrate as such.

Psychosocial Distress in Women With Breast Cancer and Their Partners and Its Impact on Supportive Care Needs in Partners

Objectives

While both patients and informal caregivers report high levels of cancer-related distress, supportive care needs of relatives are often not taken into account and little is known about mutual perception of distress within couples. Therefore, we aimed to investigate distress in female patients with breast cancer and their male partners as well as supportive care needs in partners.

Methods

In this cross-sectional study, we recruited women with breast cancer during primary cancer care and their male partners, obtained information on mental distress and supportive care needs through visual analog scales for four mood domains and the Short Form of Supportive Care Needs Survey (SCNS-SF34).

Results

Among 250 eligible patients with breast cancer, 102 patients (40.8%) and their male partners participated. Partners reported higher levels of distress (p = 0.02), whereas patients (self-assessment) indicated stronger needs for help (p < 0.001). Men with higher levels of distress were younger (p < 0.001), and reported a shorter relationship duration (p = 0.001) compared to partners with lower distress. Partners overestimated distress, anxiety, depression, and need for help in the patient. Patients overestimated partners need for help. The majority of partners (78%) reported at least one unmet need, most frequently related to the health system and information domain.

Conclusion

A systematic distress and needs assessment for women with breast cancer and their male partners is mandatory. The provision of optimal supportive care depends on protocols that include not only psychosocial care for patients but also procedures for managing distress and needs for partners including individual and couple-based interventions.

Association Between Serum Uric Acid and Depression in Patients with Chronic Kidney Disease not Requiring Kidney Dialysis: Cross-Sectional and Longitudinal Analyses

BACKGROUND Depression is the main problem of psycho-nephrology. We aimed to investigate clinical risk factors for depression in patients with non-dialysis chronic kidney disease (CKD). MATERIAL AND METHODS A non-dialysis CKD cohort study was conducted with 223 patients. Information on demographic and clinical parameters was collected at baseline. Beck Depression Inventory (BDI) and Pittsburgh Sleep Quality Index (PSQI) questionnaires were used to estimate depression and sleep quality in the patients. The questionnaires were repeated in 158 patients after 6 months. Logistic regression was performed to identify independent factors associated with depression and any longitudinal changes in BDI scores. RESULTS At baseline, 17 patients (7.72%) in the CKD cohort presented with depression. Multivariate logistic regression revealed that being female (odds ratio [OR] 0.319, 95% confidence interval [CI] 0.108 to 0.944, P=0.039) and having lower levels of serum uric acid (SUA) (OR 0.675, 95% CI 0.469 to 0.970, P=0.034) were independent risk factors for depression. A decrease in PSQI score (OR 0.873, 95% CI 0.777 to 0.981, P=0.022) and an increase in SUA level (OR 1.383, 95% CI 1.115 to 1.715, P=0.003) were independently associated with decline in BDI scores in the patients in the 6-month follow-up group. CONCLUSIONS Lower SUA levels and being female were independent risk factors for depression in non-dialysis CKD patients. Improving sleep quality and increasing SUA levels may relieve depression to some extent.

Red and Processed Meat Consumption and Risk of Depression: A Systematic Review and Meta-Analysis

Depression is one of the leading causes of disability worldwide, with more than 264 million people affected. On average, depression first appears during the late teens to mid-20s as result of a complex interaction of social, psychological and biological factors. The aim of this systematic review with meta-analysis is to assess the association between red and processed meat intake and depression (both incident and prevalent). This systematic review was conducted according to the methods recommended by the Cochrane Collaboration and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Relevant papers published through March 2020 were identified by searching the electronic databases MEDLINE, Embase and Scopus. All analyses were conducted using ProMeta3 software. A critical appraisal was conducted. Finally, 17 studies met the inclusion criteria. The overall effect size (ES) of depression for red and processed meat intake was 1.08 [(95% CI = 1.04; 1.12), p-value < 0.001], based on 241,738 participants. The results from our meta-analysis showed a significant association between red and processed meat intake and risk of depression. The presented synthesis will be useful for health professionals and policy makers to better consider the effect of diet on mental health status.

Depression and anxiety in Hodgkin lymphoma patients: A Danish nationwide cohort study of 945 patients

Cancer-related psychological distress may lead to depression and anxiety among survivors. The vast majority of patients with Hodgkin lymphoma (HL) become long-term survivors, but the risk of mental health problems after HL is not well-characterized. Using national population-based registries, we investigated the cumulative incidence of psychotropic drug (antidepressants, antipsychotics, and anxiolytics) use (proxies for depression and anxiety) in HL patients as well as if an increased risk would normalize over time for patients in remission. The study included 945 HL patients aged 18-92 years and 4725 matched persons. In total, 215 HL patients (22.8%) received a prescription of any psychotropic drug (PD) at some point after date of diagnosis compared to 545 persons (11.5%) in the matched cohort. Cumulative incidences with death/relapse as competing risk confirmed that HL patients were at higher risk of receiving psychotropic drug prescriptions, but the increased risk was transient and normalized to the matched population 5 years into survivorship. Increased age, Eastern Cooperative Oncology Group performance status, and disease stage were associated with higher risk of psychotropic drug prescriptions. Given the increased rate of psychotropic drug prescriptions after HL diagnosis, screening for symptoms of depression and anxiety is warranted after HL diagnosis and first years into survivorship.

Depression is independently associated with increased length of stay and readmissions in multimorbid inpatients

BACKGROUND

Little is known about the impact of depression across a broad range of multimorbid patients hospitalized for reasons other than depression. The objective of the study was to investigate in a large sample of multimorbid inpatients whether ancillary depression is associated with increased length of stay (LOS) and readmissions, two important clinical outcomes with implications for healthcare utilization and costs.

METHODS

We retrospectively analyzed a cohort of 253,009 multimorbid inpatients aged ≥18 at an academic medical center, 8/2009-8/2017.

PRIMARY OUTCOME

LOS.

SECONDARY OUTCOMES

LOS related to different main diagnoses, readmissions within 1, 3, 6, 12, and 24-months after discharge.

RESULTS

Multivariable linear regression showed 24% longer LOS in patients with ancillary depression (1.24; 95% confidence interval [CI]: 1.22, 1.25). Females stayed 22% longer (1.22; 95% CI: 1.20, 1.25), males 24% (1.24; 95% CI: 1.22, 1.27). We identified 16 main diagnosis clusters in which ancillary depression was associated with significant LOS increases, with associations being strongest for "Failure and rejection of transplanted organs and tissues", "Other noninfective gastroenteritis and colitis", and "Other soft tissue disorders, not elsewhere classified". Multivariable logistic and Poisson regression showed independent associations of ancillary depression with increased readmission odds and frequencies at 1, 3, 6, 12, and 24 months.

CONCLUSIONS

Ancillary depression was independently associated with increased LOS and more readmissions across a broad range of multimorbid inpatients.

Inflammation-Induced Tryptophan Breakdown is Related With Anemia, Fatigue, and Depression in Cancer

Many patients with cancer suffer from anemia, depression, and an impaired quality of life (QoL). These patients often also show decreased plasma tryptophan levels and increased kynurenine concentrations in parallel with elevated concentrations of Th1 type immune activation marker neopterin. In the course of anti-tumor immune response, the pro-inflammatory cytokine interferon gamma (IFN-γ) induces both, the enzyme indoleamine 2,3-dioxygenase (IDO) to degrade tryptophan and the enzyme GTP-cyclohydrolase I to form neopterin. High neopterin concentrations as well as an increased kynurenine to tryptophan ratio (Kyn/Trp) in the blood of cancer patients are predictive for a worse outcome. Inflammation-mediated tryptophan catabolism along the kynurenine pathway is related to fatigue and anemia as well as to depression and a decreased QoL in patients with solid tumors. In fact, enhanced tryptophan breakdown might greatly contribute to the development of anemia, fatigue, and depression in cancer patients. IDO activation and stimulation of the kynurenine pathway exert immune regulatory mechanisms, which may impair anti-tumor immune responses. In addition, tumor cells can degrade tryptophan to weaken immune responses directed against them. High IDO expression in the tumor tissue is associated with a poor prognosis of patients. The efficiency of IDO-inhibitors to inhibit cancer progression is currently tested in combination with established chemotherapies and with immune checkpoint inhibitors. Inflammation-mediated tryptophan catabolism and its possible influence on the development and persistence of anemia, fatigue, and depression in cancer patients are discussed.

Prevalence and associated factors of depressive symptoms among chronic kidney disease patients in China: Results from the Chinese Cohort Study of Chronic Kidney Disease (C-STRIDE)

OBJECTIVE

Depression is the most common mental disorder in patients with chronic kidney disease (CKD), and previous studies have found that: (a) depression can accelerate the progression of CKD; and (b) depression is an independent risk factor for hospitalization and death among patients with CKD. Therefore, the objective of the current study was to investigate the prevalence of depression in Chinese patients with CKD, and to identify variables associated with depression.

METHODS

The study analyzed baseline data from a multicenter prospective cohort study of Chinese patients with chronic kidney disease (the C-STRIDE study). In all, 2995 participants in CKD stages 1 to 4 who completed a survey of depressive symptoms were included in the analyses. Depressive symptoms were assessed by the Zung Self-Rating Depression Scale (ZSDS). A ZSDS ≥50 was used as the cut-off score for the presence of depressive symptoms. Multivariable logistic regression was used to identify variables associated with depression.

RESULTS

The mean estimated glomerular filtration rate (eGFR) in the study sample was 51.59±29.49 ml/min/1.73 m². The prevalence of depressive symptoms was 37.8% and increased significantly with CKD stage. Being female, a higher level of education, a low income, a larger economic impact of disease cost, comorbid cardiovascular disease, anemia, and impaired physical ability were independently associated with depressive symptoms.

CONCLUSION

Our study revealed that depressive symptoms were common among patients with CKD in China. Sociodemographic variables and the clinical characteristics of disease severity were strongly associated with depressive symptoms.

Distress Management, Version 3.2019, NCCN Clinical Practice Guidelines in Oncology

Distress is defined in the NCCN Guidelines for Distress Management as a multifactorial, unpleasant experience of a psychologic (ie, cognitive, behavioral, emotional), social, spiritual, and/or physical nature that may interfere with the ability to cope effectively with cancer, its physical symptoms, and its treatment. Early evaluation and screening for distress leads to early and timely management of psychologic distress, which in turn improves medical management. The panel for the Distress Management Guidelines recently added a new principles section including guidance on implementation of standards of psychosocial care for patients with cancer.

Adherence to antidepressant medications is associated with reduced premature mortality in patients with cancer: A nationwide cohort study

BACKGROUND

Depression and anxiety are common in cancer and antidepressants (AD) are efficacious treatment. The relationship between AD adherence and mortality in cancer is unclear. This study aimed to evaluate the association between adherence to AD and all-cause mortality in a population-based cohort of patients with cancer.

MATERIALS AND METHODS

We conducted a 4-year historical prospective cohort study including 42,075 patients with cancer who purchased AD at least once during the study period. Adherence to AD was modeled as nonadherence (<20%), poor (20-50%), moderate (50-80%), and good (>80%) adherence. We conducted multivariable survival analyses adjusted for demographic and clinical variables that may affect mortality.

RESULTS

During 1,051,489 person-years at risk follow-up, the adjusted hazard ratios (HR) for mortality were 0.89 (95% confidence interval [CI]: 0.83-0.95), 0.77 (95% CI: 0.66-0.72), and 0.80 (95% CI: 0.76-0.85) for the poor, moderate, and good adherence groups, respectively, compared to the nonadherent group. Analysis of the entire sample and a subgroup with depression, for cancer subtypes, revealed similar patterns for breast, colon, lung, and prostate cancers, but not for melanoma patients. Multivariate predictors of premature mortality included male gender (HR 1.48 [95% CI: 1.42-1.55]), current/past smoking status (HR 1.1, [95% CI: 1.04-1.15]; P < .0001), low socioeconomic status (HR 1.1, [95% CI: 1.03-1.17]; P < .0001) and more physical comorbidities.

CONCLUSIONS

The present study is the first to demonstrate that higher adherence to AD is associated with a decrease of all-cause mortality in a large nationwide cohort of cancer patients. Our data add to the pressing need to encourage adherence to AD among cancer patients.

Acceptance and Commitment Therapy in Cancer: Review of Applications and Findings

This study aimed to analyze published studies regarding the usefulness of Acceptance and Commitment Therapy in the treatment of oncological patients. A systematic review of the literature was conducted using the Web of Science, Google Scholar and Dialnet (2000-2016). Nineteen articles fulfilled the inclusion criteria. Those patients who received interventions based on Acceptance and Commitment Therapy showed a better emotional state and quality of life and greater psychological flexibility. Acceptance and Commitment Therapy proved to be useful in the psychological treatment of oncological patients. However, the heterogeneity and limitations of the studies, principally with regard to sample characteristics, study design and manner in which mechanisms responsible for changes are evaluated, make further studies necessary with a view to ascertaining what patient and/or intervention characteristics might improve results. Randomized controlled trials comparing the efficacy of Acceptance and Commitment Therapy with no treatment, with treatment with placebo and with other efficacious therapies, including a study of medium- and long-term results, would be of particular interest.

Real-World Direct Health Care Costs Associated with Psychotropic Polypharmacy Among Adults with Common Cancer Types in the United States

BACKGROUND

Psychotropic polypharmacy is not uncommon among cancer patients and may contribute to the increased direct health care cost burden in this population.

OBJECTIVE

To estimate average direct health care costs in the year following cancer diagnosis among cancer patients receiving psychotropic polypharmacy compared with those without psychotropic polypharmacy, using a multivariable analysis framework.

METHODS

A retrospective cross-sectional study was conducted among patients aged 18 years and older diagnosed with the most commonly occurring cancers (breast, prostate, lung, and colorectal) in the United States during 2011-2012 using the deidentified Optum Clinformatics Data Mart commercial claims database. Psychotropic polypharmacy was defined as concurrent use of 2 or more psychotropic medications for at least 90 days. Direct health care costs in the year following cancer diagnosis were estimated as total medical payments made by the health plans and were derived from claims files. A generalized linear regression model with log-link function and gamma distribution was used to model average direct health care costs, controlling for baseline patient demographic and clinical covariates.

RESULTS

Average annual direct health care costs for cancer patients with psychotropic polypharmacy ($53,497; SD $72,590) were higher than those without psychotropic polypharmacy ($38,255; SD $59,844), with an unadjusted average cost difference of $15,242 (P < 0.0001). In the adjusted regression model, the average difference in costs shrunk to $5,888 but remained notable. When examined by type of cancer, average direct health care costs for all cancer patients with psychotropic polypharmacy were significantly higher than those for patients without psychotropic polypharmacy, except for colorectal cancer patients.

CONCLUSIONS

Overall health care costs were higher among cancer patients with psychotropic polypharmacy compared with those without psychotropic polypharmacy. Our findings support the need for future research to better understand the benefits and risks of psychotropic polypharmacy, given its potential to cause adverse health outcomes and avoidable health care utilization and costs for this vulnerable patient population.

Prevalence of depression in patients with cancer in Iran: a systematic review and meta-analysis

Introduction

It is generally accepted that depression, affecting the quality of life, is a serious and common complication in patients with cancer. Given that there is no integrated study on this topic in Iran, the present study sought to investigate the prevalence of depression in patients with cancer by a systematic review and meta-analysis.

Methods

To meet the study objectives, all English and Persian papers published from 2000 to January 2018 were systematically collected and the data were extracted for analysis.

Results

There were 14 studies which were selected on the basis of the inclusion and exclusion criteria. A total number of 2831 patients with cancer had participated in the studies. The prevalence of depression among Iranian patients with cancer was 35% (95% CI 16% to 70%) based on random effects model. Among various types of cancer, the highest prevalence of depression appeared to patients suffering from breast cancer.

Conclusion

The prevalence of depression among patients with cancer in Iran was higher than the developed countries. As depression affects the quality of life of patients with cancer, the results can help policymakers and service providers in planning to reduce the prevalence of depression.

Interactions between antidepressants, sleep aids and selected breast cancer therapy

Depression and insomnia are very significant pathologies in cancer patients as they contribute to the patient’s overall cure and quality of life. Moreover, untreated depression and ongoing insomnia are associated with decreased immune responses and lower survival rates. With all disease states and especially with cancer, close attention to drug-drug interactions and the potential impact on the efficacy of therapy is paramount. One area of particular interest due to the lack of well-done clinical trials is drug-drug interaction(s) between antidepressants and cancer treatment. Pharmacokinetics of a certain drug allows for prediction of certain drug interactions based on chemical properties of the agents involved. If the agents depend on their metabolites for activity, active drug level will be decreased through this enzyme inhibition. In this paper, we looked at the cytochrome-P450 drug interactions between antidepressants and sleep aids with Selective Estrogen Receptor Modulators (SERM). Newer SERM metabolisms are less influenced by interactions with medications used to treat depression. However, tamoxifen metabolism could be severely altered by several antidepressants. This has direct consequences as patients on tamoxifen and antidepressant can have double the risk of relapse to cancer in two years. We discussed those interactions and made recommendations for clinical use.

The use of antidepressants in oncology: a review and practical tips for oncologists

Background

The use of psychotropic drugs, namely those with an antidepressant profile (ADs), is a mandatory part of an integrated treatment of psychiatric disorders among cancer patients. We aimed to synthetize the most relevant data emerging from published studies to provide tips about the use of ADs in oncology.

Design

A search was made of the major databases over the last 30 years (Embase/Medline, PsycLIT, PsycINFO, the Cochrane Library), including narrative reviews, systematic reviews and meta-analyses summarizing the results from observational studies and randomized clinical trials assessing effectiveness, safety profile, interactions, contraindications and use of ADs in oncology with regard to both psychiatric (depressive spectrum, stress-related, anxiety disorders) and cancer-related symptoms (e.g. pain, hot flashes and fatigue).

Results

The weight of evidence supports the efficacy of ADs for more severe major depression in individuals with cancer and as an adjuvant treatment in cancer-related symptoms, although the methodological limitations of reported randomized controlled trials do not permit definite conclusions. Data also indicate that there should be caution in the use of ADs in cancer patients in terms of their safety profile and potential clinically significant interactions with other prescribed medications. Practical recommendations that have been made for the use of ADs in cancer patients, in the context of a multimodal approach to depression treatment, have been summarized here.

Conclusions

ADs are a relatively safe and effective treatment for more severe major depression in cancer patients. However, more research is urgently needed regarding the efficacy of ADs in different cancer types and cancer settings, their interactions with anticancer agents and their additive benefit when integrated with psychosocial interventions.

Exploring comorbid depression and physical health trajectories: A case-based computational modelling approach

While comorbid depression/physical health is a major clinical concern, the conventional methods of medicine make it difficult to model the complexities of this relationship. Such challenges include cataloguing multiple trends, developing multiple complex aetiological explanations, and modelling the collective large-scale dynamics of these trends. Using a case-based complexity approach, this study engaged in a richly described case study to demonstrate the utility of computational modelling for primary care research. N = 259 people were subsampled from the Diamond database, one of the largest primary care depression cohort studies worldwide. A global measure of depressive symptoms (PHQ-9) and physical health (PCS-12) were assessed at 3, 6, 9, and 12 months and then annually for a total of 7 years. Eleven trajectories and 2 large-scale collective dynamics were identified, revealing that while depression is comorbid with poor physical health, chronic illness is often low dynamic and not always linked to depression. Also, some of the cases in the unhealthy and oscillator trends remain ill without much chance of improvement. Finally, childhood abuse, partner violence, and negative life events are greater amongst unhealthy trends. Computational modelling offers a major advance for health researchers to account for the diversity of primary care patients and for developing better prognostic models for team-based interdisciplinary care.

Antidepressants for the treatment of depression in people with cancer

BACKGROUND

Major depression and other depressive conditions are common in people with cancer. These conditions are not easily detectable in clinical practice, due to the overlap between medical and psychiatric symptoms, as described by diagnostic manuals such as the Diagnostic and Statistical Manual of Mental Disorders (DSM) and International Classification of Diseases (ICD). Moreover, it is particularly challenging to distinguish between pathological and normal reactions to such a severe illness. Depressive symptoms, even in subthreshold manifestations, have been shown to have a negative impact in terms of quality of life, compliance with anti-cancer treatment, suicide risk and likely even the mortality rate for the cancer itself. Randomised controlled trials (RCTs) on the efficacy, tolerability and acceptability of antidepressants in this population are few and often report conflicting results.

OBJECTIVES

To assess the efficacy, tolerability and acceptability of antidepressants for treating depressive symptoms in adults (aged 18 years or older) with cancer (any site and stage).

SEARCH METHODS

We searched the following electronic bibliographic databases: the Cochrane Central Register of Controlled Trials (CENTRAL 2017, Issue 6), MEDLINE Ovid (1946 to June week 4 2017), Embase Ovid (1980 to 2017 week 27) and PsycINFO Ovid (1987 to July week 4 2017). We additionally handsearched the trial databases of the most relevant national, international and pharmaceutical company trial registers and drug-approving agencies for published, unpublished and ongoing controlled trials.

SELECTION CRITERIA

We included RCTs comparing antidepressants versus placebo, or antidepressants versus other antidepressants, in adults (aged 18 years or above) with any primary diagnosis of cancer and depression (including major depressive disorder, adjustment disorder, dysthymic disorder or depressive symptoms in the absence of a formal diagnosis).

DATA COLLECTION AND ANALYSIS

Two review authors independently checked eligibility and extracted data using a form specifically designed for the aims of this review. The two authors compared the data extracted and then entered data into Review Manager 5 using a double-entry procedure. Information extracted included study and participant characteristics, intervention details, outcome measures for each time point of interest, cost analysis and sponsorship by a drug company. We used the standard methodological procedures expected by Cochrane.

MAIN RESULTS

We retrieved a total of 10 studies (885 participants), seven of which contributed to the meta-analysis for the primary outcome. Four of these compared antidepressants and placebo, two compared two antidepressants, and one three-armed study compared two antidepressants and placebo. In this update we included one additional unpublished study. These new data contributed to the secondary analysis, while the results of the primary analysis remained unchanged.For acute-phase treatment response (6 to 12 weeks), we found no difference between antidepressants as a class and placebo on symptoms of depression measured both as a continuous outcome (standardised mean difference (SMD) -0.45, 95% confidence interval (CI) -1.01 to 0.11, five RCTs, 266 participants; very low certainty evidence) and as a proportion of people who had depression at the end of the study (risk ratio (RR) 0.82, 95% CI 0.62 to 1.08, five RCTs, 417 participants; very low certainty evidence). No trials reported data on follow-up response (more than 12 weeks). In head-to-head comparisons we only retrieved data for selective serotonin reuptake inhibitors (SSRIs) versus tricyclic antidepressants, showing no difference between these two classes (SMD -0.08, 95% CI -0.34 to 0.18, three RCTs, 237 participants; very low certainty evidence). No clear evidence of a beneficial effect of antidepressants versus either placebo or other antidepressants emerged from our analyses of the secondary efficacy outcomes (dichotomous outcome, response at 6 to 12 weeks, very low certainty evidence). In terms of dropouts due to any cause, we found no difference between antidepressants as a class compared with placebo (RR 0.85, 95% CI 0.52 to 1.38, seven RCTs, 479 participants; very low certainty evidence), and between SSRIs and tricyclic antidepressants (RR 0.83, 95% CI 0.53 to 1.30, three RCTs, 237 participants). We downgraded the certainty (quality) of the evidence because the included studies were at an unclear or high risk of bias due to poor reporting, imprecision arising from small sample sizes and wide confidence intervals, and inconsistency due to statistical or clinical heterogeneity.

AUTHORS' CONCLUSIONS

Despite the impact of depression on people with cancer, the available studies were very few and of low quality. This review found very low certainty evidence for the effects of these drugs compared with placebo. On the basis of these results, clear implications for practice cannot be deduced. The use of antidepressants in people with cancer should be considered on an individual basis and, considering the lack of head-to-head data, the choice of which agent to prescribe may be based on the data on antidepressant efficacy in the general population of individuals with major depression, also taking into account that data on medically ill patients suggest a positive safety profile for the SSRIs. To better inform clinical practice, there is an urgent need for large, simple, randomised, pragmatic trials comparing commonly used antidepressants versus placebo in people with cancer who have depressive symptoms, with or without a formal diagnosis of a depressive disorder.

A descriptive analysis of depression and pain complaints among patients with cancer in a low income country

BACKGROUND

In high income countries, cancer is one of the leading causes of death, with co-morbid depression contributing to the risk of increased mortality. However, both cancer and depression are neglected conditions in low income countries. The current study assessed the magnitude of depression and the association of pain complaints with depression among patients with cancer in a low income country.

METHOD

In this cross-sectional study participants were 390 patients with established diagnosis of cancer, who were recruited consecutively when visiting a tertiary treatment centre in Addis Ababa, Ethiopia. The occurrence of depression was determined using the nine items Patient Health Questionnaire (PHQ-9). Major depressive disorder was confirmed: (1) when five or more of the PHQ-9 symptoms were endorsed as occurring for at least 'more than seven days', with the exception of suicidal ideation item which counted as a positive rating if it had occurred even once in the previous fifteen days. (2) one of the symptoms has to be either depressed mood or loss of interest. Pain complaint was measured by Numeral Rating Scale (NRS) and severity of pain was assessed using Verbal Rating Scale (VRS).

RESULTS

The prevalence of major depressive disorder was 16.4% (95%CI: 13.1%, 20.4%), and subthreshold depression was 17.4% (95%CI: 14.0%, 21.5%). Pain complaints occurred in 69.0% (95%CI: 64.3%, 73.4%) of the participants. The odds of having a major depressive symptom was over four times higher among participants who had pain.

LIMITATIONS

The study was cross sectional and liable to recall bias. Recruitment was carried out in a tertiary referral hospital, which might lead to the selection of more economically well-off and educated participants limiting generalizability of the study. Moreover, we did not control for cancer types, which may be related to pain and the experience of depression. Some of the somatic symptoms in PHQ9 may also be related to the cancer itself.

CONCLUSIONS

This study highlights the clinical significance of both depression and pain complaints in patients with cancer in a low income country. Exploration of the impact of depressive disorders on quality of life and outcome of cancer is an important area for further research in low income countries.

Drug-drug interactions involving antidepressants: focus on desvenlafaxine

Psychiatric and physical conditions often coexist, and there is robust evidence that associates the frequency of depression with single and multiple physical conditions. More than half of patients with depression may have at least one chronic physical condition. Therefore, antidepressants are often used in cotherapy with other medications for the management of both psychiatric and chronic physical illnesses. The risk of drug-drug interactions (DDIs) is augmented by complex polypharmacy regimens and extended periods of treatment required, of which possible outcomes range from tolerability issues to lack of efficacy and serious adverse events. Optimal patient outcomes may be achieved through drug selection with minimal potential for DDIs. Desvenlafaxine is a serotonin-norepinephrine reuptake inhibitor approved for the treatment of adults with major depressive disorder. Pharmacokinetic studies of desvenlafaxine have shown a simple metabolic profile unique among antidepressants. This review examines the DDI profiles of antidepressants, particularly desvenlafaxine, in relation to drugs of different therapeutic areas. The summary and comparison of information available is meant to help clinicians in making informed decisions when using desvenlafaxine in patients with depression and comorbid chronic conditions.

CYP2D6 variability in populations from Venezuela

CYP2D6 is an important cytochrome P450 enzyme that plays an important role in the metabolism of about 25% of currently prescribed drugs. The presence of polymorphisms in the CYP2D6 gene may modulate enzyme level and activity, thereby affecting individual responses to pharmacological treatments. The most prevalent diseases in the admixed population from Venezuela are cardiovascular and cancer, whereas viral, bacterial and parasitic diseases, particularly malaria, are prevalent in Amerindian populations; in the treatment of these diseases, several drugs that are metabolized by CYP2D6 are used. In this work, we reviewed the data on CYP2D6 variability and predicted metabolizer phenotypes, in healthy volunteers of two admixed and five Amerindian populations from Venezuela. The Venezuelan population is very heterogeneous as a result of the genetic admixture of three major ethnical components: Europeans, Africans and Amerindians. There are noticeable inter-regional and inter-population differences in the process of mixing of this population. Hitherto, there are few published studies in Venezuela on CYP2D6; therefore, it is necessary to increase research in this regard, in particular to develop studies with a larger sample size. There is a considerable amount of work remaining before CYP2D6 is integrated into clinical practice in Venezuela.

Impact of depression treatment on health-related quality of life among adults with cancer and depression: a population-level analysis

PURPOSE

Cancer diagnosis in adults is often accompanied by negative impacts, which increase the risk of depression thereby lowering health-related quality of life (HRQoL). We examined the association between depression treatment and HRQoL among US adults with cancer and depression.

METHODS

Patients age 18 and above, with self-reported cancer and depression diagnoses were identified from Medical Expenditure Panel Survey database for 2006-2013. Baseline depression treatment was categorized as antidepressants only, psychotherapy with or without antidepressant use, and no reported use of antidepressants or psychotherapy. HRQoL was measured using SF-12 physical component summary (PCS) and mental component summary (MCS) scores. Adjusted ordinary least squares regressions estimated the association between type of depression treatment and HRQoL.

RESULTS

Out of 450 (weighted per calendar year: 2.1 million) cancer adults included in the study, 51% received antidepressants only, while 16% received psychotherapy with or without antidepressants. In bivariate analyses, the mean MCS score was lowest among those who received psychotherapy with or without antidepressants compared to those receiving antidepressants only and those with no reported use of either modality, p < 0.05. In multivariate analyses, there was no significant difference in HRQoL by type of depression treatment.

CONCLUSION

Despite treatment for depression, HRQoL did not improve during the measurement timeframe. Quality of life is a priority health outcome in cancer treatment, yet our findings suggest that current clinical approaches to ameliorate depression in cancer patients appear to be suboptimal.

IMPLICATIONS FOR CANCER SURVIVORS

Adults with cancer and comorbid depression should receive appropriate depression care in order to improve their HRQoL.

Association among presence of cancer pain, inadequate pain control, and psychotropic drug use

INTRODUCTION

Pain is a common symptom in cancer patients, and its control and management are complex. Despite the high concomitant use of psychotropic drugs among such patients, the association among pain, inadequate pain control, and psychotropic drug use has not been fully determined. This study examined the prevalence of cancer pain and inadequate pain control and the association with psychotropic drug use.

MATERIALS AND METHODS

In this cross-sectional study, we investigated 402 medical records obtained by simple random sampling of oncology patients at a hospital in northern Spain from July 2012 to July 2014. Adjusted odds ratios (ORs) were estimated together with their 95% confidence intervals (95% CIs) by unconditional logistic regression for each type of psychotropic drug (anxiolytics, hypnotics, and antidepressants).

RESULTS

The mean patient age was 61.17 (standard deviation ± 13.14) years; 57.5% were women, 42.5% men. Pain was present in 18.4% of patients and inadequate pain control in 54.2%. We found a statistically significant association between the presence of cancer pain and anxiolytic use (adjusted OR, 3.15; 95% CI, 1.49-6.68) and hypnotic use (adjusted OR, 5.19; 95% CI, 1.77-15.25). Inadequate pain control was associated to a greater extent with the use of those drugs: adjusted OR for anxiolytic use, 4.74 (95% CI, 1.91-11.80); adjusted OR for hypnotic use, 6.09 (95% CI, 1.74-21.32). By contrast, no association was found between pain and antidepressant use (adjusted OR, 0.99).

CONCLUSION

The presence of pain and (to a greater extent) poor pain control were associated with increased use of certain psychotropic drugs, such as anxiolytics and hypnotics. There appeared to be no association between pain and antidepressant use.

Depressive spectrum disorders in cancer: prevalence, risk factors and screening for depression: a critical review

BACKGROUND

Although depression and mood-related disorders are common in persons with cancer, these conditions remain frequently overlooked in clinical practice. Negative consequences of depressive disorder spectrum have been reported (e.g. suicidal ideation, increase physical complications and somatic symptoms, negative influence on prognosis), indicating the need for routine screening, assessment and management.

METHODS

A search of the major databases (Medline, Embase, PsycLIT, PsycINFO, and the Cochrane Library) was conducted on the reviews and meta-analyses available in order to summarize relevant data concerning depressive disorders spectrum in terms of prevalence, risk factors, and screening and assessment among patients with cancer across the trajectory of the disease.

RESULTS

The data show a prevalence of depression and depressive disorders between 5% and 60% according to the different diagnostic criteria, the tools used in the studies (e.g. semi-structured psychiatric interview and psychometric questionnaires), as well as the stage and type of cancer. Furthermore, despite the significant health care resources devoted to cancer care and the importance of addressing depressive symptoms, assessment and management of depressive spectrum disorders in cancer patients remains suboptimal.

CONCLUSIONS

Routine screening and adequate assessment of depressive spectrum disorders is necessary in patients with cancer in order to effectively manage the multifaceted and complex consequences on cancer care.

Behavioural Effects of Using Sulfasalazine to Inhibit Glutamate Released by Cancer Cells: A Novel target for Cancer-Induced Depression

Despite the lack of robust evidence of effectiveness, current treatment options for cancer-induced depression (CID) are limited to those developed for non-cancer related depression. Here, anhedonia-like and coping behaviours were assessed in female BALB/c mice inoculated with 4T1 mammary carcinoma cells. The behavioural effects of orally administered sulfasalazine (SSZ), a system x_c⁻ inhibitor, were compared with fluoxetine (FLX). FLX and SSZ prevented the development of anhedonia-like behaviour on the sucrose preference test (SPT) and passive coping behaviour on the forced swim test (FST). The SSZ metabolites 5-aminosalicylic acid (5-ASA) and sulfapyridine (SP) exerted an effect on the SPT but not on the FST. Although 5-ASA is a known anti-inflammatory agent, neither treatment with SSZ nor 5-ASA/SP prevented tumour-induced increases in serum levels of interleukin-1β (IL-1β) and IL-6, which are indicated in depressive disorders. Thus, the observed antidepressant-like effect of SSZ may primarily be attributable to the intact form of the drug, which inhibits system x_c⁻. This study represents the first attempt at targeting cancer cells as a therapeutic strategy for CID, rather than targeting downstream effects of tumour burden on the central nervous system. In doing so, we have also begun to characterize the molecular pathways of CID.

Systematic review and meta-analysis of collaborative care interventions for depression in patients with cancer

BACKGROUND

Previous systematic reviews have found limited evidence for the effectiveness of pharmacological and psychological interventions for the management of depression in patients with cancer. This paper provides the first meta-analysis of newer collaborative care interventions, which may include both types of treatment, as well as integrated delivery and follow-up. Meta-analyses of pharmacological and psychological interventions are included as a comparison.

METHODS

A search of MEDLINE, EMBASE, PsycINFO, and the Cochrane Library from July 2005 to January 2015 for randomized controlled trials of depression treatments for cancer patients diagnosed with a major depressive disorder, or who met a threshold on a validated depression rating scale was conducted. Meta-analyses were conducted using summary data.

RESULTS

Key findings included eight reports of four collaborative care interventions, eight pharmacological, and nine psychological trials. A meta-analysis demonstrated that collaborative care interventions were significantly more effective than usual care (standardized mean difference = -0.49, p = 0.003), and depression reduction was maintained at 12 months. By comparison, short-term (up to 12 weeks), but not longer-term effectiveness was demonstrated for both pharmacological and psychological interventions.

CONCLUSIONS

Collaborative care interventions have newly emerged as multidisciplinary care delivery models, which may result in more long-term depression remission. This review also updates previous findings of modest evidence for the effectiveness of both pharmacological and psychological interventions for threshold depression in cancer patients. Research designs focusing on combined treatments and delivery systems may best further the limited evidence-base for the management of depression in cancer.
