Depressive Spectrum Disorders in Cancer: Diagnostic Issues and Intervention. A Critical Review

Efficacy and safety of behavioural activation on depression in people with co-occurring non-communicable diseases: systematic review and meta-analysis

BACKGROUND

People with non-communicable diseases (NCDs) have a higher prevalence of comorbid depression than the general population. While previous research has shown that behavioural activation is effective for general depression, its efficacy and safety in treating depression associated with NCDs remains unclear.

AIMS

To compare the efficacy and safety of behavioural activation against comparators in reducing depression symptoms in people with NCDs.

METHOD

We searched six databases from inception until 30 March 2023 (updated 23 September 2024) for randomised controlled trials (RCTs) comparing behavioural activation with comparators for depression in people with NCDs. Risk of bias was assessed using the Cochrane Collaboration's 'risk-of-bias 2 tool'. We calculated a random-effects, inverse-variance weighting meta-analysis.

RESULTS

Of the 21 386 initial studies, 12 RCTs (with 2144 patients) comparing behavioural activation with any comparator on treatment outcomes for depression with comorbid NCD met the inclusion criteria. Six studies rated as low risk of bias. For short-term follow-ups (up to 6 months), meta-analysis showed behavioural activation had little effect on depression symptom improvement in people with NCDs (Hedges' g = -0.24; 95% CI, -0.62 to 0.15), compared to comparators, with high heterogeneity (I2 = 91.91%). Of the 12 included studies, three RCTs provided data on adverse events occurring during the trial.

CONCLUSIONS

Evidence from this systematic review is not sufficient to draw clear conclusions about the efficacy and safety of behavioural activation for reducing depression symptoms in people with NCDs. Future reviews need to include more high-quality, well-designed RCTs to better understand the potential benefits of behavioural activation for comorbid depression.

Epidemiological profile of breast cancer patients: descriptive study at the Laâyoune Sakia El Hamra Region Oncology Center

This research, conducted in the Laâyoune-Sakia El Hamra Region in southern Morocco from January 2021 to December 2022, aims to describe the epidemiological profile of cancer patients at the Laâyoune Oncology Center. By following 90 patients who were under observation at the oncology center, the study sought to provide comprehensive insights into their sociodemographic and clinical characteristics. The study used a two-part questionnaire administered to 90 cancer patients at an ocular oncology center. The first part collected sociodemographic data such as age, marital status and place of residence, and the second part focused on clinical details including stage of diagnosis and treatment. It was found that the incidence of cancer among women over the age of 50 years in this study was 54.4%. Grade 1 was classified as high-grade, while grades 2 and 3 were not negative for hormone receptors. No significant differences were observed between the two groups in terms of risk factors or clinical parameters. However, the placebo group showed a greater preference for mammograms. About 84.4% of patients were diagnosed at stage I, while 15% showed double, triple or squamous cell carcinoma. No significant time differences were observed. Treatment details were available for more than 90% of patients and 3.3% of them underwent surgery with chemotherapy and/or radiation. The study revealed that breast cancer among older women patients is more common than in younger women in the study area. The study confirms the need for specific strategies for cancer screening and management in this region and to take necessary measures.

Adjunctive Intranasal Esketamine for Comorbid Treatment-Resistant Depression with Suicidal Ideation in Patients Receiving Palliative Care at a Comprehensive Cancer Center: A Case Series

Background: The psychiatric needs of those with cancer and other advanced illnesses are becoming increasingly recognized. Ketamine is emerging as a promising treatment option for depressive disorders in psychiatric and palliative care. In the palliative care setting, its study has been hindered by lack of consistent administration routes and dosing. Intranasal (IN) esketamine (Spravato®) has recently received U.S. Food and Drug Administration (FDA) approval as an adjunctive agent for treatment-resistant depression (TRD) and major depressive disorder (MDD) with suicidal ideation (SI). Objective: We sought to offer IN esketamine to patients suffering from TRD and SI at a comprehensive cancer center. Methods: We designed and implemented a protocol to administer IN esketamine and describe three cases in which it was provided to patients with TRD and SI at a palliative care clinic in the United States. Results: Following treatment, all three patients had substantial reduction in depression severity and no further suicidalideation. These improvements were maintained for up to a year. No serious adverse events occurred. Conclusions: These cases illustrate the potential utility of IN esketamine in the palliative care setting.

Top Ten Tips Palliative Care Clinicians Should Know About the Physical Manifestations of Psychiatric Illness and Treatment

Addressing the psychiatric aspects of serious illness in palliative care (PC) is crucial to both care delivery and outcomes. Psychiatric comorbidities are common among patients with PC needs and can significantly impact their total burden of symptomatic distress, overall quality of life, functional independence, and healthcare utilization. Yet, these aspects of care are often deferred to mental health consultant teams in the context of busy PC services and often limited human resources. To provide comprehensive and person-centered care, PC clinicians must understand the interplay between medical conditions and psychiatric presentations within a biopsychosocial framework to respond empathically, efficiently, and effectively. This article is the first of a two-part series developed in collaboration with a group of psychiatric-palliative care specialists. This article explores ten common physical manifestations of psychiatric illness and treatment among patients facing serious illnesses. The second article will provide pragmatic tips PC clinicians should know about the psychiatric manifestations of nonpsychiatric serious illness and treatment. Combined, these two articles support a holistic approach that PC clinicians can use to prioritize and integrate both mental and emotional well-being throughout the continuum of serious illness.

Reconceptualizing mental health in cancer survivorship

Mental health for cancer survivors in both research and clinical applications has strongly adopted a traditional nosological approach, involving the classification of psychopathology into discrete disorders. However, this approach has recently faced considerable criticism due to issues such as high comorbidity and within-disorder symptom heterogeneity across populations. Moreover, there are additional specific issues impacting the validity of traditional approaches in cancer survivorship populations, including the physiological effects of cancer and its treatments. In response, we provide the case for the hierarchical dimensional approach within psycho-oncology, in particular the Hierarchical Taxonomy of Psychopathology (HiTOP). We discuss not only the potential utility of HiTOP to research and clinical applications within psycho-oncology, but also its limitations, and what is required to apply this approach within cancer survivorship.

Is it time to discard the Diagnostic and Statistical Manual of Mental Disorders (DSM) in psycho-oncology?

The conceptual basis of psychopathology within cancer survivorship is critical, as the chosen conceptualisation informs assessment and explanatory models, as well as interventions and supportive care approaches. The validity of a chosen conceptualisation of psychopathology is therefore paramount for ensuring cancer survivors receive high-quality and efficacious care and support that can be iteratively improved via coordinated research efforts. In this paper, we discuss the traditional diagnostic approach to conceptualising psychopathology within cancer care, including the diagnostic system the 'Diagnostic and Statistical Manual of Mental Disorders' (DSM) [1], and the significant issues it presents within cancer survivorship. We detail and discuss how an alternate conceptualisation of psychopathology may enhance both research and practice within psycho-oncology. We ultimately pose, and provide our perspective, on the question "Is it Time to Discard the DSM in Psycho-Oncology?"

Hotspots and frontiers of the relationship between gastric cancer and depression: A bibliometric study

BACKGROUND

A significant relationship between gastric cancer (GC) and depression has been found in the last 20 years. However, there is no comprehensive information that helps researchers find popular and potential research directions on GC and depression.

AIM

To determine the research status and hotspots by bibliometric analysis of relevant publications on the relationship between GC and depression.

METHODS

We used the Web of Science Core Collection to search and collate the literature on GC and depression from 2000 to 2022 on 31 May, 2023. Then, visualization analysis was performed using VOSviewer software (version 1.6.19) and the Bibliometrix package in R software.

RESULTS

We retrieved 153 pertinent publications from 2000 to 2022. The annual publication count showed an overall upward trend. China had the most prominent publications and significant contributions to this field (n = 64, 41.83%). Before 2020, most studies focused on "the effect of GC on the development and progression of depression in patients." The latest research trends indicate that "the effect of depression on the occurrence and development of GC and its mechanism" will receive more attention in the future.

CONCLUSION

The study of "the effect of depression on the occurrence and development of GC and its mechanism" has emerged as a novel research theme over the past two years, which may become a research hotspot in this field. This study provides new insights into the hotpots and frontiers of the relationship between GC and depression, potentially guiding researchers toward hot research topics in the future.

Anxiety and depression in adult cancer patients: ESMO Clinical Practice Guideline

•Anxiety and depressive disorders are common in patients with cancer. •A higher prevalence seen in patients with cancer than the general population is often underrecognised. •Psychotherapy, cognitive behavioural therapy and mindfulness-based therapies are effective treatments. •Psychopharmacological treatments have been shown to be effective treatments of anxiety and depressive disorders.

Emotional, inflammatory, and genetic factors of resilience and vulnerability to depression in patients with premenopausal breast cancer: A longitudinal study protocol

BACKGROUND

Psychosocial stress and depressive disorder have been associated with cancer as putative contributors to worse prognosis. On the other hand, cancer diagnosis is a recognised life event that can contribute to distress and depressive states. Humoral and cellular inflammation can promote depressive disorder by means of decreased monoamine synthesis, glutamate neurotoxicity, neurogenesis and neuroplasticity, dysregulated hypothalamic-pituitary-adrenal axis, and glucocorticoid resistance. This protocol objectives are to observe the interactions between psychosocial variables and biochemical and immunological biomarkers in a longitudinal, prospective design; to identify inflammation-related depression endophenotypes in breast cancer patients and to understand if early diagnosed and treated depression in this population will translate in better inflammation status and better global prognosis.

METHODS

Prospective observational cohort, composed by 100 consecutive premenopausal patients, diagnosed with non-distant metastatic breast carcinoma and with no history of major psychopathology or other organic illness. The participants will have an in-person assessment in three different moments, along illness treatment and follow-up, with respect to cytometric, immunologic, and psychosocial parameters and will be tested for depression vulnerability and resilience inflammation-related functional genetic polymorphisms. Additionally, at years 5 and 10 post enrollment, patients`medical records will be assessed. As a control cohort, all patients excluded due to psychiatric history or past psychiatric treatments will have their clinical records assessed at years 5 and 10 after admission. All the data will be managed with the SPSS® software.

DISCUSSION AND CONCLUSION

This study is an original longitudinal cohort of breast cancer premenopausal patients, with a comprehensive approach to psychosocial, clinical, inflammatory, and genetic variables. It expects to provide evidence regarding the links between genetic, cytometric, immunologic, and psychosocial factors, their potential contribution to the pathophysiology of depressive disorder, breast cancer course, progression, and prognosis. It may further contribute with data to better efficacy of the psycho-oncological interventions.

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.

Identifying unmet information needs of advanced cancer patients in Iran: An in-depth qualitative study

Background and Aims

One of the main vital needs for self-care in patients with advanced cancer is information need. Meeting this need has significant positive effects on improving their treatment and care. This study was conducted to identify the unmet information needs of patients with advanced cancer in Iran.

Methods

This exploratory study was performed from July to February 2021 in the Kerman University of Medical Sciences cancer treatment centers. Oncologists selected eligible patients by purposeful sampling method. Semistructured and in-depth interviews were conducted with selected patients to collect data. Interviews continued until data saturation. Each interview was audio-recorded and transcribed verbatim.

Results

In the interviews, 15 patients with advanced cancer ranging in age from 43 to 65 years participated. The most common type of cancer in women was breast (71.4%) and prostate (50%) in men. The two main categories of "types of unmet information needs" and "reasons for not meeting information needs" were extracted from the analysis of patient interviews, with six and four subcategories, respectively.

Conclusion

Cancer patients had a large number of unmet information needs. At the time of identifying the unmet information needs of cancer patients, the basic reasons for not meeting these needs should also be considered because cultural differences and social gaps in societies are inevitable.

Understanding the basis of major depressive disorder in oncological patients: Biological links, clinical management, challenges, and lifestyle medicine

In recent years, the incidence of different types of cancer and patient survival have been rising, as well as their prevalence. The increase in survival in recent years exposes the patients to a set of stressful factors such as more rigorous follow-up and more aggressive therapeutic regimens that, added to the diagnosis of the disease itself, cause an increase in the incidence of depressive disorders. These alterations have important consequences for the patients, reducing their average survival and quality of life, and for these reasons, special emphasis has been placed on developing numerous screening tests and early recognition of depressive symptoms. Despite that cancer and major depressive disorder are complex and heterogeneous entities, they also share many critical pathophysiological mechanisms, aiding to explain this complex relationship from a biological perspective. Moreover, a growing body of evidence is supporting the relevant role of lifestyle habits in the prevention and management of both depression and cancer. Therefore, the present study aims to perform a thorough review of the intricate relationship between depression and cancer, with a special focus on its biological links, clinical management, challenges, and the central role of lifestyle medicine as adjunctive and preventive approaches to improve the quality of life of these patients.

Longitudinal Association of Universal Screening and Treatment for Major Depressive Disorder with Survival in Cancer Patients

Evidence for clinical screening and intervention for depression in cancer and the effect of this intervention on cancer prognosis is suboptimal. This study substantialized a complete model with universal screening and intervention for major depressive disorder (MDD) and explored its effect on survival in patients. This longitudinal study recruited cancer patients routinely screened for MDD with a two-stage model. Data including sex, age, cancer diagnosis, first diagnosis date, date of death, cancer stage, and MDD diagnosis and treatment were collected from medical records and the national registration system for cancer. Kaplan−Meier’s survival analysis and the Cox proportional hazards regression model were applied to analyze the effects of associated factors on survival. Further subgroup analysis for 14 types of cancer primary site was also performed. Overall, the hazard for patients adhering to psychiatric treatment for MDD before cancer diagnosis was not statistically different from that for patients without MDD (hazard ratio (HR) = 1.061, 95% CI: 0.889−1.267, p = 0.512). The hazard for patients adhering to psychiatric treatment after cancer diagnosis was significantly lower than that for patients without MDD (HR = 0.702, 95% CI: 0.607−0.812, p < 0.001). Those who were diagnosed with MDD after cancer diagnosis and adhered poorly to psychiatric treatment had the greatest hazard (HR = 1.829, 95% CI: 1.687−1.984, p < 0.001). The effect of intervention for MDD varied across different primary cancer types.

Associations Between Personality Traits, Perceived Stress and Depressive Symptoms in Gynecological Cancer Patients Characterized by the Short and Long Allele Variant of the 5-HTTLPR Genotype: Preliminary Results

Objective

The study explored associations between personality traits, perceived stress and symptoms of depression in oncological patients characterized by the two variants of the serotonin transporter (5-HTTLPR) polymorphisms.

Method

The sample was composed of 41 gynecological cancer patients who completed self-reported questionnaires including the NEO Five-Factor Inventory, the dimension of depression-dejection (D/D) of the Profile of Moods State and the Perceived Stress Scale (PSS). The polymerase chain reaction was also employed to identify genotypes in the serotonin (5HTT) polymorphism.

Results

The one-way ANOVA test, across the 5-HTTLPR genotype groups, showed significant effects of the short variants on neuroticism (p=0.009) and of the long variant on agreeableness (p=0.022), as well as a tendency to a statistical significance of the l/l variant on consciousness (p=0.074). Bivariate correlations showed positive correlations of neuroticism with both psychopathological symptoms (D/D r=0.522; PSS r=0.586) in the combined group S, negative association of agreeableness with depression (D/D r=-0.613) and of consciousness with depression (D/D r=-0.750) and perceived stress (PSS r=-0.702) in the group of the long variant of 5-HT-TLPR genotype.

Conclusions

Personalized medicine should consider the interaction between genotype and phenotype in reducing levels of clinical psychological distress, highlighting how psychotherapeutic processes should improve patients' quality of life.

Characterization of Depressive Symptoms Trajectories After Breast Cancer Diagnosis in Women in France

Importance

Breast cancer (BC) diagnosis and treatment expose patients to a 5-fold higher risk of depression compared with the general population, with an estimated prevalence of 10% to 25%. A depressive episode in patients with BC has implications for the tolerance of and adherence to treatment, impairing quality of life and reducing life expectancy.

Objective

To identify and characterize distinct longitudinal patterns of depressive symptoms in patients with BC from diagnosis to 3 years after treatment.

Design, Settings, and Participants

The CANTO-DEePRESS (Deeper in the Understanding and Prevention of Depression in Breast Cancer Patients) cohort study included women in the French multicenter CANTO (CANcer TOxicities) cohort study (conducted between March 20, 2012 and December 11, 2018), who were 18 years or older with invasive stage I to III BC and no previous BC treatment. The study aimed to characterize toxicities over a 5-year period following stage I to III primary BC treatment. Assessments of depressive symptoms were performed on a subset of patients with available data at diagnosis and at least 2 other time points. All data were extracted from the CANTO database on October 1, 2020.

Main Outcomes and Measures

The primary outcome was the level of depressive symptoms at each assessment time point measured with the Hospital Anxiety and Depression Scale and depression subscale at BC diagnosis and at 3 to 6, 12, and 36 months after the end of treatment. The group-based trajectory modeling was used to identify trajectory groups, and multinomial logistic regression models were used to characterize the following factors associated with trajectory group affiliation: demographic, socioeconomic, clinical, lifestyle, and quality-of-life data.

Results

A total of 4803 women (mean [SD] age, 56.2 [11.2] years; 2441 patients [50.8%] with stage I BC) were included in the study. Six trajectory groups that described the heterogeneity in the expression of depressive symptoms were identified: noncases with no expression of symptoms (n = 2634 [54.8%]), intermediate worsening (1076 [22.4%]), intermediate improvement (480 [10.0%]), remission (261 [5.4%]), delayed occurrence (200 [4.2%]), and stable depression (152 [3.2%]). HADS-D scores at diagnosis were consistently associated with the 5 depressive trajectory group affiliations, with an estimated higher probability per point increase of experiencing subthreshold or clinically significant depressive symptoms between diagnosis and the 3 years after the end of BC treatment. The higher probabilities ranged from 1.49 (95% CI, 1.43-1.54) for the intermediate worsening group to 10.53 (95% CI, 8.84-12.55) for the stable depression group. Trajectory groups with depressive symptoms differed from the noncases group without symptoms by demographic and clinical factors, such as having dependent children, lower household income, cancer stage, family history of BC, previous psychiatric hospitalizations, obesity, smoking status, higher levels of fatigue, and depression at diagnosis.

Conclusions and Relevance

In this cohort study, nearly a third of patients with BC experienced temporary or lasting significant depressive symptoms during and after treatment. Improving early identification of women at risk of developing long-term or delayed depression is therefore critical to increase quality of life and overall survival. Subjected to validation, this study is an important first step toward personalized care of patients with BC at risk of depression.

Psychopharmacology in the Pediatric Oncology and Bone Marrow Transplant Units: Antidepressant Treatment

Objectives: The aim of this study was to characterize the clinical profiles, tolerability, and efficacy of two groups of antidepressants, selective serotonin reuptake inhibitors (SSRIs), and the atypical antidepressant, mirtazapine, in children and adolescents treated in a large pediatric Hematology-Oncology center. Methods: A review of computerized medical charts of 32 pediatric patients with cancer, from December 2011 to April 2020, was conducted. Efficacy and tolerability of antidepressant medications were retrospectively analyzed. The Clinical Global Impressions-Severity (CGI-S) and Clinical Global Impressions-Improvement (CGI-I) Scales were used to evaluate psychiatric symptoms severity before and following treatment, while the data on adverse events and drug-drug interactions were retrieved from the computerized medical records. Results: Thirty-two children and adolescents with cancer, 2-21 years of age (mean 14.1 ± 4.6 years), were treated with antidepressants. Fourteen patients (44%) received mirtazapine, whereas 18 patients (56%) received SSRIs: sertraline (25%), escitalopram (25%), or fluoxetine (6%). Treatment choice was dictated either by physician preference or informed by potential drug-drug interactions. The most common psychiatric diagnoses were major depressive disorders (47%), anxiety disorders (19%), and medication-induced psychiatric disorders (19%). The most common psychiatric-medical symptoms were depressed mood (94%) and anxiety (62%). CGI-S improved significantly (p < 0.05) between pretreatment and on-treatment assessments, with no statistically significant difference between SSRI and mirtazapine-treated patients. CGI-I scores at reassessment indicated improvement in most patients (84%). Adverse events of treatment were mild in all patients. Conclusions: The antidepressants used in this study, SSRIs and mirtazapine, were effective and well tolerated in children and adolescents with cancer and psychiatric comorbidities. Given the high rates of depression and anxiety in children with cancer, large-scale, multisite, prospective clinical trials of antidepressants are warranted.

Factors associated with and risk factors for depression in cancer patients - A systematic literature review

Objective

The prevalence of depression in oncological patients is 3, 4-fold compared to the general population. However, the specific risk factors for these prevalence rates are not fully understood.

Methods

A systematic literature review was conducted in nine electronic databases between 2005 and 2020. The quality of the eligible studies was appraised by two persons using the adapted 11-items Downs and Black checklist.

Results

Among 2010 potentially relevant articles, 40 studies were eligible, with 27 studies of high quality and 13 studies of moderate quality. A total of 156 factors associated with depression were identified which were clustered into somatic, psychological, social and sociodemographic factors. Pre-existing depression and personality factors were the most consistent associated factors with depression in cancer patients, while for most somatic and treatment-related factors only modest associations were found.

Conclusions

Grouped as bio-psycho-social associated factors, somatic factors showed a modest influence, whereas social relationship (support) and previous depression are unequivocally significantly associated with depression.

Language, Speech, and Facial Expression Features for Artificial Intelligence-Based Detection of Cancer Survivors' Depression: Scoping Meta-Review

BACKGROUND

Cancer survivors often experience disorders from the depressive spectrum that remain largely unrecognized and overlooked. Even though screening for depression is recognized as essential, several barriers prevent its successful implementation. It is possible that better screening options can be developed. New possibilities have been opening up with advances in artificial intelligence and increasing knowledge on the connection of observable cues and psychological states.

OBJECTIVE

The aim of this scoping meta-review was to identify observable features of depression that can be intercepted using artificial intelligence in order to provide a stepping stone toward better recognition of depression among cancer survivors.

METHODS

We followed a methodological framework for scoping reviews. We searched SCOPUS and Web of Science for relevant papers on the topic, and data were extracted from the papers that met inclusion criteria. We used thematic analysis within 3 predefined categories of depression cues (ie, language, speech, and facial expression cues) to analyze the papers.

RESULTS

The search yielded 1023 papers, of which 9 met the inclusion criteria. Analysis of their findings resulted in several well-supported cues of depression in language, speech, and facial expression domains, which provides a comprehensive list of observable features that are potentially suited to be intercepted by artificial intelligence for early detection of depression.

CONCLUSIONS

This review provides a synthesis of behavioral features of depression while translating this knowledge into the context of artificial intelligence-supported screening for depression in cancer survivors.

Prevalence of Depression and Cancer - A systematic review

Objective: While comorbidity of different forms of cancer and clinical depression is reported for many single studies, representative and global overviews are scarce. Methods: A systematic review was carried out (mainly based on Medline, Embase, Cochrane, PsychLit, and Psyndex) to identify studies in adult cancer patients from 2007 to 2019. Studies with noncancer populations and cancer survivors were excluded. Assessment methods of depression were chart-based diagnoses, interview-based and self-report questionnaires. Quality and plausibility were checked using the adapted Downs & Black checklist. Results: For all 210 included studies the prevalence rate of clinical depression varied from 7.9 % to 32.4 %, with a mean of 21.2 % depression for different (mixed) cancer entities. The different methods of assessment have led to under- (especially charts-based diagnoses) as well as overreporting for some forms of cancer. In general, the different assessment forms show an acceptable variation in prevalence. Conclusions: The risk for a cancer patient to suffer a clinical depression during the first year after diagnoses is 15 % to 20 %, meaning every fifth or sixth patients. Different cancer entities, stage of cancer and treatments as well as different cultural and medical backgrounds show only slight variation in prevalence rates.

Relationship between Green and Blue Spaces with Mental and Physical Health: A Systematic Review of Longitudinal Observational Studies

There is growing interest in the ways natural environments influence the development and progression of long-term health conditions. Vegetation and water bodies, also known as green and blue spaces, have the potential to affect health and behaviour through the provision of aesthetic spaces for relaxation, socialisation and physical activity. While research has previously assessed how green and blue spaces affect mental and physical wellbeing, little is known about the relationship between these exposures and health outcomes over time. This systematic review summarised the published evidence from longitudinal observational studies on the relationship between exposure to green and blue space with mental and physical health in adults. Included health outcomes were common mental health conditions, severe mental health conditions and noncommunicable diseases (NCDs). An online bibliographic search of six databases was completed in July 2020. After title, abstract and full-text screening, 44 eligible studies were included in the analysis. Depression, diabetes and obesity were the health conditions most frequently studied in longitudinal relationships. The majority of exposures included indicators of green space availability and urban green space accessibility. Few studies addressed the relationship between blue space and health. The narrative synthesis pointed towards mixed evidence of a protective relationship between exposure to green space and health. There was high heterogeneity in exposure measures and adjustment for confounding between studies. Future policy and research should seek a standardised approach towards measuring green and blue space exposures and employ theoretical grounds for confounder adjustment.

Health-Related Quality of Life: Longitudinal Analysis From the Time of Breast Biopsy Into the Post-treatment Period

Background: The physical, psychological, social, and spiritual quality of life (QoL) may be affected by breast cancer diagnosis and treatment, with mixed findings for psychological quality of life and cognitive ability performance. The present study aimed to evaluate QoL in women over 1 year from biopsy for a breast abnormality. Methods: Self-reported measures of physical, psychological, social, and spiritual QoL were obtained after biopsy results but prior to treatment initiation (baseline), 4 and 12 months later. CogState computerized neuropsychological screening battery also provided an evaluation of psychological QoL. Three groups of women including those with benign biopsy results, those with malignancy treated with chemotherapy, and those with malignancy not treated with chemotherapy were compared at 4 and 12 months after adjusting for baseline to isolate the effects of treatment. Additional covariates included are age, level of education, and income. Results: Benign biopsy results group included 72 women, whereas malignancy was found in 87 women of whom 33 were treated with chemotherapy and 54 without chemotherapy. At the time of diagnosis, women with cancer had worse psychological and social QoL but better spiritual QoL than those with benign biopsy results. Only CogState monitoring accuracy was worse for women with cancer compared with the controls at the time of biopsy results. After adjusting for QoL at baseline, women treated for cancer had worse physical and social QoL at 4 and 12 months later. Psychological well-being was worse for women with cancer at 4th month but improved at 1 year. No differences in cognition were found at 4 and 12 months when adjusted for baseline cognition and covariates. Discussion: Breast cancer is a traumatic life event for women, affecting psychological and social QoL domains, yet increasing spiritual QoL. Later, cancer treatment worsens physical, psychological, and social QoL compared with those without cancer. Conclusions: These findings suggest that interventions to improve psychological QoL may be especially important at the time of cancer diagnosis, while interventions to improve physical well-being are the most needed during and following cancer treatment. Support to improve social QoL is needed from the time of diagnosis into post-treatment survivorship.

Exploring the care needs of Iranian patients with cancer: a qualitative content analysis

BACKGROUND‏: Cancer is currently one of the most critical health problems worldwide. Different studies have shown that disease can reduce people's ability to take care of themselves and this makes them face many needs. Therefore, this study aimed to investigate unmet needs faced by patients with cancer‏. METHODS: This study employed a conventional, qualitative content analysis method. Data saturation was achieved after interviewing 13 participants in 15 interview sessions. With the in-depth semi-structured approach, the participants were asked to narrate their experiences of self-care needs in the process of disease. The collected data were analyzed using Graneheim and Lundman's method through the following steps: Construction of the units of analysis, construction of codes of meaning, condensation, extracting codes, and categorization (subcategories, categories, and the core category) ‏. RESULTS‏: Data analysis revealed two main categories. The first category was "Deficiency in disease management" with three subcategories: "the need to get rid of annoying physical symptoms"," the need for a caregiver to help with the daily routine", and "feeling frustrated and giving up treatment". The second main category covered "the need for sympathetic and knowledgeable caregivers" with the following five subcategories:" the need for sympathy and interaction with the nurse", "the need to hear the truth about the illness ", "the need for appropriate therapeutic interaction from physicians", "Inadequate qualification of medical secretaries about the patient", and" need for advice from psychologists for psychological adaptation‏". CONCLUSION‏: The most critical need reported by the patients was the need for compassionate and informed caregivers. So nursing management and care with kindness, competence, and conscience is the fundamental right of patients with cancer. Identifying patients' needs and problems can be used as a background for increasing the knowledge and experience of nurses and providing care for patients with cancer‏.

Patient-provider discussion about emotional and social needs, mental health outcomes, and benefit finding among U.S. Adults living with cancer

Background

A discussion about patient's nonmedical needs during treatment is considered a crucial component of high‐quality patient–provider communication. We examined whether having a patient–provider discussion about cancer patients’ emotional and social needs is associated with their psychological well‐being.

Methods

Using the 2016–2017 Medical Expenditure Panel Survey‐Experiences with Cancer Survivorship Supplement (MEPS–ECSS) data, we identified the cancer survivors in the United States (US) who reported having a detailed discussion about emotional and social needs during cancer care. We used multivariable logistic regression to assess the association between having a patient–provider discussion and the patients’ psychological well‐being outcomes (depressive symptoms, severe psychological distress, and worrying about cancer recurrence/worsening condition) and benefit finding experience after a cancer diagnosis.

Results

Among 1433 respondents (equivalent to 13.8 million cancer survivors in the US), only 33.6% reported having a detailed patient–provider discussion about their emotional and social needs. Having a discussion was associated with 55% lower odds (odds ratio [OR], 0.45; 95% confidence interval [CI], 0.26–0.77) of having depressive symptoms and 97% higher odds (OR, 1.97; 95% CI, 1.46–2.66) of having benefit finding experience. There was no statistically significant association between patient–provider discussion and psychological distress or worrying about cancer recurrence/worsening.

Conclusion

Detailed patient–provider discussion about the cancer patients’ emotional and social needs was associated with a lower likelihood of depressive symptoms and a higher likelihood of experiencing benefit finding. These findings stress the importance of improving the patient–provider discussion about psychosocial needs in cancer survivorship.

Carnosine improves aging-induced cognitive impairment and brain regional neurodegeneration in relation to the neuropathological alterations in the secondary structure of amyloid beta (Aβ)

Aging-induced proteinopathies, including deterioration of amyloid beta (Aβ) conformation, are associated with reductions in endogenous levels of carnosine and cognitive impairments. Carnosine is a well-known endogenous antioxidant, which counteracts aging-induced Aβ plaque formation. The aim of this study was to investigate the effects of exogenous carnosine treatments on aging-induced changes (a) in the steady-state level of endogenous carnosine and conformation of Aβ secondary structure in the different brain regions (cerebral cortex, hippocampus, hypothalamus, pons-medulla, and cerebellum) and (b) cognitive function. Young (4 months) and aged (18 and 24 months) male albino Wistar rats were treated with carnosine (2.0 μg kg^-1  day^-1 ; i.t.) or equivalent volumes of vehicle (saline) for 21 consecutive days and were tested for cognition using 8-arm radial maze test. Brains were processed to assess the conformational integrity of Aβ plaques using Raman spectroscopy and endogenous levels of carnosine were measured in the brain regions using HPLC. Results indicated that carnosine treatments improved the aging-induced deficits in cognitive function and reduced the β-sheets in the secondary structure of Aβ protein, as well as mitigating the reduction in the steady-state levels of carnosine and spine density in the brain regions examined. These results thus, suggest that carnosine can attenuate the aging-induced: (a) conformational changes in Aβ secondary structure by reducing the abundance of β-sheets and reductions in carnosine content in the brain regions and (b) cognitive impairment.

Coincident Patterns of Suicide Risk Among Adult Patients with a Primary Solid Tumor: A Large-Scale Population Study

BACKGROUND

Suicide rate is much higher in cancer patients than in general population. This study examined the suicide risk in survivors of primary solid tumor across 19 cancer sites considering risk coincident patterns based on area-based SES indicators.

METHODS

A retrospective search of the SEER database was conducted. Independent risk factors for suicide were identified using the Cox proportional-hazards model. Exploratory factor analysis and cluster analysis were used to create coincident patterns of SES factors.

RESULTS

Suicide risk was higher for patients with a primary solid tumor who were older, male, white, unmarried, had no insurance, poorly differentiated, distant metastasis and did not undergo active treatment (especially surgery). The suicide risk was higher for patients living in areas with economic and education disadvantage, high levels of immigration and crowding, and high levels of residential instability. Concomitant presence of high economic and education disadvantage, high immigration and crowding levels and low residential instability, showed the highest risk of suicide.

CONCLUSION

In order to mitigate suicidal risk, clinicians should pay more attention to patients who are older, male, white, not married, high levels of cancer severity, not received active treatment (especially surgery), and having no insurance. Identifying coincident patterns of suicide help further screen high suicidal risk patients based on area-based socioeconomic status.

Effectiveness of a brief manualized intervention, Managing Cancer and Living Meaningfully (CALM), adapted to the Italian cancer care setting: Study protocol for a single-blinded randomized controlled trial

Patients with advanced cancer suffer from psychosocial distress that may impair quality of life and that may be ameliorated by psychotherapeutic treatment. We describe here the methodology of a randomized controlled trial (RCT) to assess the effectiveness of a novel, brief, semi-structured psychotherapeutic intervention to reduce distress and increase well-being in patients with advanced or metastatic cancer. The intervention, called Managing Cancer and Living Meaningfully (CALM), was originally developed in Canada and we are now testing its Italian adaptation (CALM-IT).

The study is a single-blinded phase III RCT with assessment at baseline, 3 and 6 months with two conditions: CALM-IT versus a nonspecific supportive intervention (SPI). Eligibility criteria include: ≥ 18 years of age; fluency in the Italian language; no cognitive deficit, and diagnosis of advanced or metastatic cancer with an expected survival of 12–18 months. CALM-IT includes up to 12 sessions, delivered over 6 months and covers 4 domains: i) Symptom Management and Communication with Health Care Providers; ii) Changes in Self and Relations with Close Others; iii) Sense of Meaning and Purpose; and iv) the Future and Mortality. The primary outcome is difference in severity of depressive symptoms between treatment arm and the primary endpoint is 6 months. The secondary endpoint is 3 months and secondary outcomes are: generalized anxiety, distress about dying and death, demoralization, spiritual well-being, attachment security, posttraumatic growth, communication with partners, quality of life, and satisfaction with clinical care.

If shown to be effective, CALM-IT can be implemented nationally to relieve distress and to promote psychological well-being in patients with advanced cancer.

Depression in the medically ill

BACKGROUND

Depressive disorders are significantly more common in the medically ill compared to the general population. Depression is associated with worsening of physical symptoms, greater healthcare utilization and poorer treatment adherence. The present paper provides a critical review on the assessment and management of depression in the medically ill.

METHODS

Relevant articles pertaining to depression in the medically ill were identified, reviewed and synthesized qualitatively. A systematic review was not performed due to the large breadth of this topic, making a meaningful summary of all published and unpublished studies not feasible. Notable studies were reviewed and synthesized by a diverse set of experts to provide a balanced summary.

RESULTS

Depression is frequently under-recognized in medical settings. Differential diagnoses include delirium, personality disorders and depressive disorders secondary to substances, medications or another medical condition. Depressive symptoms in the context of an adjustment disorder should be initially managed by supportive psychological approaches. Once a mild to moderate major depressive episode is identified, a stepped care approach should be implemented, starting with general psychoeducation, psychosocial interventions and ongoing monitoring. For moderate to severe symptoms, or mild symptoms that are not responding to low-intensity interventions, the use of antidepressants or higher intensity psychotherapeutic interventions should be considered. Psychotherapeutic interventions have demonstrated benefits with small to moderate effect sizes. Antidepressant medications have also demonstrated benefits with moderate effect sizes; however, special caution is needed in evaluating side effects, drug-drug interactions as well as dose adjustments due to impairment in hepatic metabolism and/or renal clearance. Novel interventions for the treatment of depression and other illness-related psychological symptoms (e.g. death anxiety, loss of dignity) are under investigation.

LIMITATIONS

Non-systematic review of the literature.

CONCLUSION

Replicated evidence has demonstrated a bidirectional interaction between depression and medical illness. Screening and stepped care using pharmacological and non-pharmacological interventions is merited.

Neutrophil to Lymphocyte Ratio in Lung Cancer: Implications for Depressive Symptoms and Survival

Background:

Depression very commonly appears in the presence of lung cancer. Multiple contexts have shown that depression is associated with inflammation. The Neutrophil to Lymphocyte Ratio (NLR) provides an easy to interpret the measure of both inflammation and immunity, but its use as an inflammatory biomarker has not been evaluated in patients with lung cancer. We hypothesize that NLR will be elevated in depressed patients with lung cancer and that both elevated NRL and depression will have prognostic implications.

Methods:

Patients (n=109) were assessed for depression and anxiety using the Hospital .Anxiety and Depression Scale (HADS) and for distress using the Distress Thermometer. NLR was derived from a complete blood count obtained on the day of the cross-sectional survey. Data were dichotomized (NLR ≥5 and HADS-D ≥8) and analysed for survival estimations using Kaplan-Meier plots.

Results:

NLR was found to be significantly correlated with depression (r=.21, p=.03) and was associated with depression while controlling for age, sex, and marital status (β=.21, p=.004). NLR trended toward correlation with anxiety (r=.19, p=.07). Elevated NLR (≥5) predicted for worse survival (chi square= 10.08, p=.001), which was similarly seen when combined with meeting depression criteria (chi square = 16.00,p<.001).

Conclusion:

NLR provides a reasonable assessment of lung cancer related inflammation with survival implications that may indicate the presence of depression. These results warrant further research.

Challenges in rehabilitation of patients with nontraumatic spinal cord dysfunction due to tumors : A narrative review

The incidence of cancer-associated non-traumatic spinal cord dysfunction is rising due to population aging and better cancer treatment. The overall benefit of rehabilitation in specialized facilities for traumatic spinal cord dysfunction has been confirmed many times. Because of their fragility and multiple comorbidities cancer patients still face challenges to complete rehabilitation in the spinal rehabilitation facilities. In this narrative review we describe specific aspects, challenges in rehabilitation and opportunities to improve care. A literature search was performed in the PubMed database from 1 January 1978 to 30 November 2018. The focus was to find publications that discuss challenges and opportunities for rehabilitation of patients with non-traumatic spinal cord dysfunction due to a tumor. Most publications described the benefits of rehabilitation in specialized facilities. There were only few publications about survival and functional outcomes after rehabilitation for this patient population. Overall benefits including fewer complications associated with spinal cord dysfunction, less pain and depression, and better quality of life were shown. Within the past decades increasing number of publications revealed a growing interest for this group of patients. Despite major progress in cancer treatment, patients still have a limited vital prognosis and access to specialized rehabilitation units because of the concerns about the medical complexity. Patients with spinal cord tumors can benefit in areas of functionality, mood, quality of life, and survival from inpatient rehabilitation programs, in spite of the increased medical comorbidities.

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.

Smartphone Sensors for Monitoring Cancer-Related Quality of Life: App Design, EORTC QLQ-C30 Mapping and Feasibility Study in Healthy Subjects

Quality of life (QoL) indicators are now being adopted as clinical outcomes in clinical trials on cancer treatments. Technology-free daily monitoring of patients is complicated, time-consuming and expensive due to the need for vast amounts of resources and personnel. The alternative method of using the patients' own phones could reduce the burden of continuous monitoring of cancer patients in clinical trials. This paper proposes monitoring the patients' QoL by gathering data from their own phones. We considered that the continuous multiparametric acquisition of movement, location, phone calls, conversations and data use could be employed to simultaneously monitor their physical, psychological, social and environmental aspects. An open access phone app was developed (Human Dynamics Reporting Service (HDRS)) to implement this approach. We here propose a novel mapping between the standardized QoL items for these patients, the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and define HDRS monitoring indicators. A pilot study with university volunteers verified the plausibility of detecting human activity indicators directly related to QoL.

Integrating mental health with other non-communicable diseases

Mental disorders often coexist with other non-communicable diseases and they share many risk factors. Dan Stein and colleagues examine the evidence for an integrated approach

Conley Y, Hammer M, Katsaragakis S, M. Kober K, D. Levine J, McCann L, Patiraki E, P. Furlong E, A. Fox P, M. Paul S, Ream E, Wright F, Miaskowski C. Learning from data to predict future symptoms of oncology patients

Effective symptom management is a critical component of cancer treatment. Computational tools that predict the course and severity of these symptoms have the potential to assist oncology clinicians to personalize the patient's treatment regimen more efficiently and provide more aggressive and timely interventions. Three common and inter-related symptoms in cancer patients are depression, anxiety, and sleep disturbance. In this paper, we elaborate on the efficiency of Support Vector Regression (SVR) and Non-linear Canonical Correlation Analysis by Neural Networks (n-CCA) to predict the severity of the aforementioned symptoms between two different time points during a cycle of chemotherapy (CTX). Our results demonstrate that these two methods produced equivalent results for all three symptoms. These types of predictive models can be used to identify high risk patients, educate patients about their symptom experience, and improve the timing of pre-emptive and personalized symptom management interventions.

Cancer and suicidal ideation and behaviours: protocol for a systematic review and meta-analysis

INTRODUCTION

Prevalence of suicidal ideation (SI) and behaviours are higher among patients with cancer than general population. No systematic review/meta-analysis investigated this topic; therefore, our aim will be to assess the relationship between cancer and SI and behaviours.

METHODS

We will search PubMed/MEDLINE, EMBASE, SCOPUS, Web of Science, PsycINFO and Cochrane Library databases from their inception until 30 June 2018. Case-control and cohort studies focused on the association between cancer (any type) and suicidal outcomes (suicide, suicide attempt and SI) will be included. Two team members will independently: (A) perform the selection of the included studies and data extraction, with the supervision of a third member in case of discrepancies and (B) assess each study with: (1) Newcastle-Ottawa Scale (NOS); (2) Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement; (3) Grading of Recommendations Assessment, Development and Evaluation (GRADE). We will conduct a random-effects meta-analysis. Individual and pooled ORs and associated 95% CIs will be calculated as well as between-study heterogeneity. We will examine the potential for publication bias. If possible, we will explore reasons for potential between-study heterogeneity.

ETHICS AND DISSEMINATION

This study does not require ethical approval. The study will be submitted to a peer-reviewed journal, will be publicly disseminated and will be the topic of research presentations.

Validation of PROMIS emotional distress short form scales for cervical cancer

OBJECTIVES

Cervical cancer patients are at high risk for emotional distress. In this study we evaluate the PROMIS emotional distress-Depression and -Anxiety Short Forms for assessing depression and anxiety in a cervical cancer population.

METHODS

A 15-item questionnaire was used in a cervical cancer biobehavioral randomized clinical trial, testing psychosocial telephone counseling (PTC) against usual care (UC). It was administered to 204 patients prior to randomization, four months post-enrollment, and nine months post-enrollment, together with legacy measures of depression. The short forms were evaluated in patients participating in this study over three time points for internal consistency, convergent validity, and responsiveness to change over time.

RESULTS

Overall, 45% and 47% of patients scored in the moderate to severe range for anxiety and depression, respectively. Internal consistency coefficients were ≥ 0.95 at baseline, 4 months, and 9 months for depression and anxiety. The average inter-item correlation was 0.65 and 0.73 at baseline assessment for depression and anxiety, respectively. The depression short form T-score was correlated with legacy distress scales ranging from 0.44-0.76, and the anxiety short form ranging from 0.45-0.78. The depression short form demonstrated sensitivity to change as patients randomized to the counseling intervention reported greater improvement over time in depression (p = 0.014), and a nonsignificant improvement in anxiety, compared to the patients receiving usual care.

CONCLUSIONS

The PROMIS depression and anxiety short forms reliably and validly assess cervical cancer-specific emotional distress, capture salient features of distress in this population, and perform as well or better than legacy measures.

The association of depression and all-cause and cause-specific mortality: an umbrella review of systematic reviews and meta-analyses

BACKGROUND

Depression is a prevalent and disabling mental disorder that frequently co-occurs with a wide range of chronic conditions. Evidence has suggested that depression could be associated with excess all-cause mortality across different settings and populations, although the causality of these associations remains unclear.

METHODS

We conducted an umbrella review of systematic reviews and meta-analyses of observational studies. PubMed, PsycINFO, and Embase electronic databases were searched through January 20, 2018. Systematic reviews and meta-analyses that investigated associations of depression and all-cause and cause-specific mortality were selected for the review. The evidence was graded as convincing, highly suggestive, suggestive, or weak based on quantitative criteria that included an assessment of heterogeneity, 95% prediction intervals, small-study effects, and excess significance bias.

RESULTS

A total of 26 references providing 2 systematic reviews and data for 17 meta-analytic estimates met inclusion criteria (19 of them on all-cause mortality); data from 246 unique studies (N = 3,825,380) were synthesized. All 17 associations had P < 0.05 per random effects summary effects, but none of them met criteria for convincing evidence. Associations of depression and all-cause mortality in patients after acute myocardial infarction, in individuals with heart failure, in cancer patients as well as in samples from mixed settings met criteria for highly suggestive evidence. However, none of the associations remained supported by highly suggestive evidence in sensitivity analyses that considered studies employing structured diagnostic interviews. In addition, associations of depression and all-cause mortality in cancer and post-acute myocardial infarction samples were supported only by suggestive evidence when studies that tried to adjust for potential confounders were considered.

CONCLUSIONS

Even though associations between depression and mortality have nominally significant results in all assessed settings and populations, the evidence becomes weaker when focusing on studies that used structured interviews and those that tried to adjust for potential confounders. A causal effect of depression on all-cause and cause-specific mortality remains unproven, and thus interventions targeting depression are not expected to result in lower mortality rates at least based on current evidence from observational studies.

Neuroimmunology of Behavioral Comorbidities Associated With Cancer and Cancer Treatments

Behavioral comorbidities (depression, anxiety, fatigue, cognitive disturbances, and neuropathic pain) are prevalent in cancer patients and survivors. These mental and neurological health issues reduce quality-of-life, which is a significant societal concern given the increasing rates of long-term survival after various cancers. Hypothesized causes of behavioral comorbidities with cancer include tumor biology, stress associated with the cancer experience, and cancer treatments. A relatively recent leading mechanism by which these causes contribute to changes in neurobiology that underlie behavior is inflammation. Indeed, both basic and clinical research indicates that peripheral inflammation leads to central inflammation and behavioral changes in other illness contexts. Given the limitations of assessing neuroimmunology in clinical populations, this review primarily synthesizes evidence of neuroimmune and neuroinflammatory changes due to two components of cancer (tumor biology and cancer treatments) that are associated with altered affective-like or cognitive behaviors in rodents. Specifically, alterations in microglia, neuroinflammation, and immune trafficking to the brain are compiled in models of tumors, chemotherapy, and/or radiation. Evidence-based neuronal mechanisms by which these neuroimmune changes may lead to changes in behavior are proposed. Finally, converging evidence in clinical cancer populations is discussed.

Symptoms of anxiety and depression among colorectal cancer survivors from the population-based, longitudinal PROFILES Registry: Prevalence, predictors, and impact on quality of life

BACKGROUND

The aims of this study were to prospectively assess symptoms of anxiety and depression among survivors of colorectal cancer (CRC), to compare these survivors with a normative population, and to identify subgroups at risk for experiencing symptoms of anxiety and/or depression across a 4-year time period. Also, the impact on health-related quality of life (HRQOL) was studied.

METHODS

The population-based Eindhoven Cancer Registry was used to select patients diagnosed with CRC between 2000 and 2009. The Hospital Anxiety and Depression Scale and the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (HRQOL) were completed by patients in 2010 (n = 2625 [73% response rate]), 2011, 2012, and 2013 and by an age- and sex-matched normative sample (n = 315) in 2011.

RESULTS

Patients reported a significantly higher prevalence of depression (19.0% vs 12.8%) and anxiety (20.9% vs 11.8%) in comparison with the norm. Anxiety was stable, whereas depression scores changed over time, although this was not clinically relevant. A longer time since diagnosis was associated with fewer depressive symptoms over time, whereas older age and being male were associated with less anxiety and more depression. Being married was associated with less anxiety and depression, and a low education level and comorbid conditions were associated with more anxiety and depression. Higher levels of symptoms of depression and anxiety were associated with a lower global quality of life and lower physical, role, cognitive, emotional, and social functioning over time.

CONCLUSIONS

Because of the increased prevalence of depression and anxiety among patients with CRC and their negative effect on HRQOL, screening and referral are of the utmost importance, especially among those who are single, have a low educational level, and have comorbid conditions, even years after diagnosis and treatment.

Impact of physical exercise in cancer survivors during and after antineoplastic treatments

Cancer patients experience symptoms and adverse effects of treatments that may last even after the end of treatments. Exercise is a safe, non-pharmacological and cost-effective therapy that can provide several health benefits in cancer patient and survivors, reducing cancer symptoms and cancer treatment side effects. The purpose of this review is to describe how the physical exercise is capable to reduce cancer symptoms and cancer treatment side effects. We realized a pragmatic classification of symptoms, dividing them into physical, psychological and psycho-physical aspects. For each symptom we discuss causes, therapies, we analyse the effects of physical exercise and we summarize the most effective type of exercise to reduce the symptoms. This review also points out what are the difficulties that patients and survivors face during the practice of physical activity and provides some solutions to overcome these barriers. Related to each specific cancer, it emerges that type, frequency and intensity of physical exercise could be prescribed and supervised as a therapeutic program, like it occurs for the type, dose and duration of a drug treatment.

Advancing psychosocial care in cancer patients

Cancer is a devastating disease causing significant psychological problems among patients and their families. In the past few decades, there have been growing implementation and dissemination of screening methods for the psychological consequences of cancer, including distress, depression, anxiety, post-traumatic stress, and demoralisation. Also, guidelines for the management of psychological distress have been developed and endorsed by a number of scientific cancer associations. This review examines some of the most significant related issues, also focusing on recent advances in psychosocial and psychopharmacological interventions as a part of a mandatory, integrated, and comprehensive approach to cancer care.
