Efficacy and safety of pharmacotherapy in cancer-related psychiatric disorders across the trajectory of cancer care: a review

Psychedelics as an intervention for psychological, existential distress in terminally ill patients: A systematic review and network meta-analysis

BACKGROUND

The interest in psychedelics as a therapeutic intervention for existential distress of people with terminal illness grounds on their mechanism of action and effect on the spiritual/existential aspects accompanying end-of-life experiences.

AIMS

This systematic review and network meta-analysis aimed at examining the efficacy and safety of psychedelic compounds for existential distress in terminally ill people.

METHODS

PubMed, CINAHL, PsycINFO, EMBASE, and clinicaltrials.gov were searched for randomized controlled trials (RCTs) administering psychedelics for existential distress in people with terminal illnesses. Meta-analysis estimated the standardized mean difference (SMD) and odds ratio (OR), with corresponding 95% confidence intervals (95% CI), between treated and control groups in pairwise and network comparisons, using random-effects models. Post-treatment measures of depression and anxiety, as proxies of existential distress, and tolerability were the primary outcomes.

RESULTS

Nine studies, involving 606 participants (362 treated with psychedelics: psilocybin, ketamine, 3,4-methylenedioxymethamphetamine, and lysergic acid diethylamide (LSD)) were included. The meta-analysis supported the efficacy of psychedelics on depression (SMD: -0.80 (95% CI: -0.98, -0.63)) and anxiety (SMD: -0.84 (95% CI: -1.20, -0.48)). Network meta-analysis identified psilocybin as the most effective compound for depression, and LSD for anxiety. However, head-to-head comparison between psychedelics did not reach statistical significance. The rates of treatment discontinuation and adverse events between psychedelics and controls were comparable.

CONCLUSIONS

Psychedelics, especially psilocybins and LSD, showed promising effects on depression and anxiety in people with terminal illnesses. Limitations include the small number of RCTs, methodological issues related to blinding, and the lack of direct comparisons between psychedelic compounds. Larger studies and comparative research are needed to consolidate these findings.

Foundations for a Personalized Psycho-Oncology: The State of the Art

Personalized psycho-oncology represents a major challenge for the holistic care of cancer patients. It focuses on individualized psychotherapeutic and psychiatric interventions to address specific psychological needs. This narrative review summarizes the current literature on personalized psycho-oncology and highlights the prevalence and impact of psychiatric/psychological disorders in cancer patients. Personalized approaches, including tailored interventions and interdisciplinary collaboration, have been shown to be effective in improving mental health and overall quality of life. The integration of inflammatory biomarkers into treatment plans is a promising but challenging way to alleviate mental health problems. In addition, there is a need for specific diagnostic tools and treatment guidelines that take into account the specific psychological impact of different types of cancer. Future research should aim to refine these personalized strategies, improve diagnostic accuracy, and evaluate the cost-effectiveness of these interventions to improve both the psychological well-being and treatment outcomes of cancer patients.

Is alcohol and psychoactive medication use associated with excess hospital length-of-stay and admission frequency? A cross-sectional, observational study

BACKGROUND

Hospital length-of-stay and admission frequency are commonly used indicators of disease burden and health resource expenditures. However, the impact of psychoactive prescription medication use and harmful alcohol consumption on both the duration and frequency of hospital admissions is under-explored.

METHODS

We conducted an analysis of data gathered from 2872 patients admitted to the Emergency Department at Lovisenberg Diaconal Hospital in Oslo, Norway. Psychoactive medicines (benzodiazepines, opioids, and z-hypnotics) were detected via liquid chromatography-mass spectrometry analysis of whole blood, while alcohol consumption was self-reported through the Alcohol Use Disorder Identification Test-4 (AUDIT-4). Using logistic regression, we examined associations with our primary outcomes, which were excess length-of-stay and admission frequency, defined as exceeding the sample median of 3.0 days and 0.2 admissions per year, respectively.

RESULTS

Compared to the absence of psychoactive medication, and after adjusting for age, gender, malignant disease, pre-existing substance use disorder and admission due to intoxication, the detection of two or more psychoactive medicines was associated with both excess length-of-stay (odds ratio [OR], 1.60; 95% confidence interval [CI], 1.20 to 2.14) and yearly hospitalization rate (OR, 3.72; 95% CI, 2.64 to 5.23). This association persisted when increasing the definition for excess length-of-stay to 4 and 5 days and to 1.0 and 1.5 admissions per year for admission frequency. Harmful alcohol consumption (AUDIT-4 scores of 9 to 16) was not associated with excess length-of-stay, but with excess admission frequency when defined as more than 1.0 admission per year when compared to scores of 4 to 6 (OR, 2.68; 95% CI, 1.58 to 4.57).

CONCLUSIONS

Psychoactive medication use is associated with both excess length-of-stay and increased antecedent admission frequency, while harmful alcohol consumption may be associated with the latter. The utility of our findings as a causal factor should be explored through intervention-based study designs.

Psilocybin-assisted group therapy in patients with cancer diagnosed with a major depressive disorder

BACKGROUND

Depression is common in patients with cancer and is associated with lower treatment adherence and reduced quality of life. Antidepressants and psychotherapy have limited success in improving depression among patients with cancer. This study explored the safety, feasibility, and efficacy of psilocybin-assisted therapy in patients with cancer and major depressive disorder.

METHODS

This phase 2, open-label trial enrolled patients with curable and noncurable cancer and major depressive disorder at a single community oncology practice site. A single 25-mg dose of psilocybin was administered simultaneously to cohorts of three to four participants with individual (4.25 hours in 1:1 therapist-to-patient ratio) and group therapeutic support (3.75 hours) before, during, and after psilocybin administration. Outcomes included depression severity, anxiety, pain, demoralization, and disability.

RESULTS

Thirty participants completed the study. No psilocybin-related serious adverse events occurred; treatment-related adverse events (e.g., nausea, headache) were generally mild and expected. There were no laboratory or electrocardiogram abnormalities. No suicidality was reported. Efficacy was suggested with a robust reduction in depression severity scores from baseline to posttreatment of 19.1 points (95% CI, 22.3 to -16.0; p < .0001) by week 8. Eighty percent of participants demonstrated a sustained response to psilocybin treatment; 50% showed full remission of depressive symptoms at week 1, which was sustained for 8 weeks.

CONCLUSIONS

Psilocybin-assisted therapy in group cohort administration was safe and feasible in patients with cancer and depression. Efficacy was suggested based on clinically meaningful reductions in depressive symptoms. The novel, group-oriented format, compact delivery time, community cancer center setting, and one-to-one therapist-to-patient ratio could also add to therapeutic gains and efficiency of administration.

TRIAL REGISTRATION

NCT04593563.

PLAIN LANGUAGE SUMMARY

Depression is common in patients with cancer and associated with lower treatment adherence, reduced quality of life, and limited response to antidepressants and psychotherapy. We conducted a phase 2 trial to study a single dose of psilocybin administered in a group therapy setting with one-to-one therapist-to-participant psychological support to patients with curable and noncurable cancer and major depressive disorder. Findings of the study showed safety (no treatment-related serious adverse events or suicidality) with psilocybin and suggested efficacy, with a significant reduction in depression severity scores from baseline to posttreatment. Further investigation is warranted.

PAM trial protocol: a randomised feasibility study of psychedelic microdosing-assisted meaning-centred psychotherapy in advanced stage cancer patients

BACKGROUND

An advanced cancer diagnosis can be associated with a significant profile of distress. Psychedelic compounds have shown clinically significant effects in the treatment of psychological distress in patients with advanced-stage cancer. Given the challenges of delivering timely and effective intervention in the advanced cancer context, it is possible that an alternative, more pragmatic, approach lies in psychedelic 'microdosing'. Microdosing refers to repeated administration of psychedelics in sub-hallucinogenic doses. The purpose of this study is to evaluate the feasibility of conducting a full-scale randomised controlled trial comparing psychedelic microdose-assisted-meaning-centred psychotherapy (PA-MCP) to standard meaning-centred psychotherapy (MCP) in New Zealand indigenous (Māori) and non-indigenous people with advanced cancer and symptoms of anxiety and/or depression. Although MCP is a well-established psychotherapeutic treatment in advanced cancer populations, the potential efficacy and effectiveness of this therapy when delivered alongside a standardised microdose regimen of a psychedelic compound have not been investigated.

METHODS

Participants with advanced-stage cancer and symptoms of anxiety and/or depression (N = 40; 20 Māori, 20 non-Māori) will be randomised under double-blind conditions to receive 7 sessions of MCP alongside 13 doses of either an LSD microdose (4-20 µg) (PA-MCP) or inactive placebo (placebo-MCP). The feasibility, acceptability, and safety of this intervention and physiological and psychological measures will be recorded at baseline, at each session of MCP, and at a 1-month and 6-month follow-up.

DISCUSSION

Our findings will evaluate the feasibility, acceptability, and safety of a larger randomised controlled trial and provide an initial indication of the potential benefits of psychedelic microdosing for psychological distress in advanced-stage indigenous and non-indigenous cancer patients.

Association between Phase Angle and Subjective Perceptions of Health Variables in Cancer Patients

The phase angle, an increasingly studied healthcare tool, was studied to explore its relationship with psychological factors in cancer patients. The aim of this study was to investigate the relationship between the phase angle (PhA), obtained by the bioimpedance analysis of body composition, and psychological factors measured by questionnaire in cancer patients. The study included 311 patients who underwent bioimpedance testing to determine their PhA value; their psychological profiles were assessed using SF-36, FACIT, QLQ-C30, and GHQ-12 questionnaires. Mixed linear regression models were used to analyze the relationship between PhA and the psychological tests. The results showed a statistical correlation between PhA and the GHQ-12, FACIT, and SF-36 questionnaires, with higher PhA values associated with better results on the questionnaires. In the QLQ-C30 questionnaire, a correlation was observed between PhA and the functioning scales (p < 0.001), except for emotional and cognitive functioning (p = 0.148 and p = 0.544, respectively), but not in most of the symptom scales. The PhA is a useful tool for assessing the subjective health perception of cancer patients, especially with regard to psychological factors. While there is a statistically significant correlation, further research is required before confidently applying it in clinical practice. The current predictive value of this predictor for certain psychological aspects is limited, underscoring the need for additional research.

Assessment of Psilocybin Therapy for Patients With Cancer and Major Depression Disorder

This nonrandomized controlled trial used a 1-to-1 therapist-to-patient ratio to administer psilocybin to groups of patients with cancer who were diagnosed with major depression disorder to create a scalable, rapidly effective depression treatment.

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.

Psychedelic/entactogen‐assisted therapy for treatment of anxiety, depression and existential distress in adult palliative care

This is a protocol for a Cochrane Review (intervention). The objectives are as follows:

To assess the benefits and harms of psychedelic/entactogen‐assisted therapy compared to placebo or active comparators (e.g. antidepressants) for treatment of anxiety, depression, and existential distress in adult palliative care.

Mental Health in Urologic Oncology

This article is a systematic review of mental health in urologic oncology patients with prostate cancer (PCa), bladder cancer (BC), renal cell carcinoma (RCC), testicular cancer (TC), or penile cancer (PeCa). For all pathologies, a focus on increasing quality of life post-treatment demonstrated a positive impact in reducing Mental Health Illness (MHI) prevalence. Cancer specific mental health care may be given to patients to reduce suicide risk in BC patients and sexual identify and masculinity counseling may improve mental health for TC or PeCa patients. In order to better accommodate patient’s mental health needs when undergoing GU cancer treatment, we recommend incorporation of mental health metrics such as questionnaires to assess early treatment of MHI, a greater emphasis on psychosocial support with the patient’s loved ones, peers, and healthcare team, alongside advising healthy habits such as exercise which has been shown to drastically reduce MHI incidence across all pathologies. We hope that these measures conducted by urologists and oncologists, alongside possible coordination with psychiatrists and psychologists for psychotherapy, psychopharmacology, and neuro-stimulation treatment modems may be helpful in the long term to reduce MHI incidence in urology oncology patients. Given the higher incidence of MHI in oncology patients and in the patient population after the Covid-19 pandemic, MHI awareness in the sphere of urologic oncologic treatment continues to be crucial when creating a collaborative treatment platform for patients.

Adaptation, implementation, and mixed methods evaluation of an interprofessional modular clinical practice guideline for delirium management on an inpatient palliative care unit

BACKGROUND

Using delirium clinical guidelines may align interprofessional clinical practice and improve the care of delirious patients and their families. The aim of this project was to adapt, implement and evaluate an interprofessional modular delirium clinical practice guideline for an inpatient palliative care unit.

METHODS

The setting was a 31-bed adult inpatient palliative care unit within a university-affiliated teaching hospital. Participants for the evaluation were interprofessional team members. Using integration of guideline adaptation and an education initiative, an interprofessional guideline adaptation group developed a face-to-face 'starter kit' module and four online self-learning modules. The mixed methods evaluation comprised pre-and post-implementation review of electronic patient records, an online survey, and analysis of focus groups/ interviews using an iterative, inductive thematic analysis approach.

RESULTS

Guideline implementation took 12 months. All palliative care unit staff attended a 'starter kit' session. Overall completion rate of the four e-Learning modules was 80.4%. After guideline implementation, nursing documentation of non-pharmacological interventions occurring before medication administration was observed. There was 60% less scheduled antipsychotic use and an increase in 'as needed' midazolam use. The online survey response rate was 32% (25/77). Most participants viewed the guideline's implementation favourably. Six key themes emerged from the qualitative analysis of interviews and focus groups with ten participants: prior delirium knowledge or experiences, challenges of facilitating change, impacts on practice, collaborative effort of change, importance of standardized guidelines, and utility of guideline elements.

CONCLUSIONS

Guideline implementation warrants concerted effort, time, and management support. Interprofessional team support facilitates the modular approach of guideline adaptation and implementation, leading to a change in clinical practice.

The Neural Signature of Psychological Interventions in Persons With Cancer: A Scoping Review

Objective:

People diagnosed with cancer have to deal with the debilitating psychological implications of this disease. Although the clinical efficacy of psychological interventions is well documented, relatively little has been written on the neural correlates of these treatments in the context of oncology. The present work is the first to provide an overall perspective of the existing literature on this topic. It also considers the potential directions for future research.

Methods:

This scoping review was carried out across 5 databases (EMBASE, PsycINFO, OVID MEDLINE, CINAHL, COCHRANE CENTRAL), from conception dates until 3 December 2021.

Results:

From an initial set of 4172 records, 13 papers were selected for this review. They consisted of 9 randomized controlled studies (RCTs), 1 quasi-experiment, 2 single case studies, and 1 secondary quantitative analysis. The studies were also heterogeneous in terms of the patient and control populations, psychological interventions, and neuroimaging methodologies used. The findings from these few studies suggest that psychological interventions in oncology patients may modulate both cortical and subcortical brain activity, consistent with the brain areas involved in distress reactions in general and to cancer specifically. The implications of this scoping review in terms of future research are also discussed.

Conclusions:

The literature on the neural correlates of psychological interventions in cancer patients is very limited, and thus requires further exploration. The provision of psychological interventions offers cancer patients a more integrated approach to care, which may in turn help preserve both the physical and the psychological wellbeing of individuals with cancer.

Challenges in Treating Cancer Patients With Unstable Psychiatric Disorder

In this review, we first present a case of chronic myeloid leukemia with acute psychosis, and then we will discuss the incidence of cancer in patients with psychotic disorders, the manifestations of new-onset psychosis, and the prevalence of preexisting psychosis in cancer patients, coupled with their impact on the treatment, diagnosis, and prognosis of cancer. This was a case that presented with acute psychosis and was found to have an elevated white blood cell count upon admission to an inpatient psychiatric unit. He was diagnosed with chronic myeloid leukemia and successfully managed with imatinib/dasatinib therapy. Psychiatrically, he was stabilized on two long-acting injectable medications to help maintain adherence. We were able to eliminate his active psychotic symptoms and return him to normal functioning in affect and thinking, achieving sustained compliance with treatment. We identified multiple inconsistencies in screening for cancer of all types in these patients, masking of signs and symptoms that would typically clue physicians to the presence of cancers, underreporting of symptoms, and disparate access to healthcare resources in patients with mental disorders when compared to the general population. Treatment of cancer in these patients as compared to the general population has also been shown to be incongruent, which will be elaborated upon. Psychiatric interventions, as well as supportive measures, for treating patients who are facing challenges during active cancer treatment will be discussed.

Psilocybin for End-of-Life Anxiety Symptoms: A Systematic Review and Meta-Analysis

OBJECTIVE

To systematically examine the effectiveness and tolerability of psilocybin for treating end-of-life anxiety symptoms.

METHODS

The Medline, Embase, CENTRAL, and PsycINFO databases were searched up to November 25, 2020. We enrolled clinical trials investigating psilocybin for treating end-of-life anxiety symptoms. Meta-analysis was conducted using random-effects model.

RESULTS

Overall, five studies were included, revealing that psilocybin was superior to the placebo in treating state anxiety at 1 day (Hedges' g, -0.70; 95% confidence interval, -1.01 to -0.39) and 2 weeks (-1.03; -1.47 to -0.60) after treatment. Psilocybin was more effective than placebo in treating trait anxiety at 1 day (-0.71; -1.15 to -0.26), 2 weeks (-1.08; -1.80 to -0.36), and 6 months (-0.84; -1.37 to -0.30) after treatment. Psilocybin was associated with transient elevation in systolic (19.00; 13.58-24.41 mm Hg) and diastolic (8.66; 5.18-12.15 mm Hg) blood pressure compared with placebo. The differences between psilocybin and placebo groups with regard to allcause discontinuation, serious adverse events, and heart rates were nonsignificant.

CONCLUSION

Psilocybin-assisted therapy could ameliorate end-of-life anxiety symptoms without serious adverse events. Because of the small sample sizes of the included studies and high heterogeneity on long-term outcomes, future randomized controlled trials with large sample sizes are needed.

Cancer Healthcare Workers' Perceptions toward Psychedelic-Assisted Therapy: A Preliminary Investigation

Recent clinical trials suggest that psychedelic-assisted therapy is a promising intervention for reducing anxiety and depression and ameliorating existential despair in advanced cancer patients. However, little is known about perceptions toward this treatment from the key gatekeepers to this population. The current study aimed to understand the perceptions of cancer healthcare professionals about the potential use of psychedelic-assisted therapy in advanced cancer patients. Twelve cancer healthcare professionals including doctors, nurses, psychologists and social workers took part in a semi-structured interview which explored their awareness and perceptions toward psychedelic-assisted therapy with advanced cancer patients. Data were analysed using thematic analysis. Four inter-connected themes were identified. Two themes relate to the role and responsibility of being a cancer healthcare worker: (1) ‘beneficence: a need to alleviate the suffering of cancer patients’ and (2) ‘non-maleficence: keeping vulnerable cancer patients safe’, and two themes relate specifically to the potential for psychedelic-assisted therapy as (3) ‘a transformative approach with the potential for real benefit’ but that (4) ‘new frontiers can be risky endeavours’. The findings from this study suggest intrigue and openness in cancer healthcare professionals to the idea of utilising psychedelic-assisted therapy with advanced cancer patients. Openness to the concept appeared to be driven by a lack of current effective treatment options and a desire to alleviate suffering. However, acceptance was tempered by concerns around safety and the importance of conducting rigorous, well-designed trials. The results from this study provide a useful basis for engaging with healthcare professionals about future research, trial design and potential clinical applications.

Antidepressants and Antipsychotic Agents as Repurposable Oncological Drug Candidates

Drug repurposing, also known as drug repositioning/reprofiling, is a relatively new strategy for the identification of alternative uses of well-known therapeutics that are outside the scope of their original medical indications. Such an approach might entail a number of advantages compared to standard de novo drug development, including less time needed to introduce the drug to the market, and lower costs. The group of compounds that could be considered as promising candidates for repurposing in oncology include the central nervous system drugs, especially selected antidepressant and antipsychotic agents. In this article, we provide an overview of some antidepressants (citalopram, fluoxetine, paroxetine, sertraline) and antipsychotics (chlorpromazine, pimozide, thioridazine, trifluoperazine) that have the potential to be repurposed as novel chemotherapeutics in cancer treatment, as they have been found to exhibit preventive and/or therapeutic action in cancer patients. Nevertheless, although drug repurposing seems to be an attractive strategy to search for oncological drugs, we would like to clearly indicate that it should not replace the search for new lead structures, but only complement de novo drug development.

Use of Medications for Treating Anxiety or Depression among Testicular Cancer Survivors: A Multi-Institutional Study

BACKGROUND

This study examined sociodemographic factors, cisplatin-related adverse health outcomes (AHO), and cumulative burden of morbidity (CBM_Pt) scores associated with medication use for anxiety and/or depression in testicular cancer survivors (TCS).

METHODS

A total of 1,802 TCS who completed cisplatin-based chemotherapy ≥12 months previously completed questionnaires regarding sociodemographic features and cisplatin-related AHOs [hearing impairment, tinnitus, peripheral sensory neuropathy (PSN), and kidney disease]. A CBM_Pt score encompassed the number and severity of cisplatin-related AHOs. Multivariable logistic regression models assessed the relationship of individual AHOs and CBM_Pt with medication use for anxiety and/or depression.

RESULTS

A total of 151 TCS (8.4%) used medications for anxiety and/or depression. No cisplatin-related AHOs were reported by 511 (28.4%) participants, whereas 622 (34.5%), 334 (18.5%), 287 (15.9%), and 48 (2.7%), respectively, had very low, low, medium, and high CBM_Pt scores. In the multivariable model, higher CBM_Pt scores were significantly associated with medication use for anxiety and/or depression (P < 0.0001). In addition, tinnitus (P = 0.0009), PSN (P = 0.02), and having health insurance (P = 0.05) were significantly associated with greater use of these medications, whereas being employed (P = 0.0005) and vigorous physical activity (P = 0.01) were significantly associated with diminished use.

CONCLUSIONS

TCS with higher CBM_Pt scores had a higher probability of using medications for anxiety and/or depression, and conversely, those who were employed and physically active tended to have reduced use of these medications.

IMPACT

Healthcare providers should encourage TCS to increase physical activity to improve both physical and mental health. Rehabilitation programs should assess work-related skills and provide career development counseling/training.

The ritual use of ayahuasca during treatment of severe physical illnesses: a qualitative study

Diseases that threaten life raise existential questions that can be a source of psychological distress. Studies with psychedelics demonstrate therapeutic effects for anxiety and depression associated with life-threatening illnesses. Ayahuasca has been proposed as a possible therapeutic agent in the treatment of psychiatric disorders. Preliminary studies suggest that ayahuasca could promote therapeutic effects for people with physical illnesses. The aim of this study was to explore how the ritual use of ayahuasca during the treatment of severe physical illnesses (SPI) may influence the way people understand and relate to their illness, using qualitative methods to assess the participants' perspectives. Participants who consumed ayahuasca ritualistically during the period of treatment for SPI were purposely chosen. Data were obtained through semi-structured interviews. A thematic analysis was performed with 14 individuals. The ritual experience with ayahuasca acted on the participants' illness understanding through multiple psychological mechanisms, including introspection, self-analysis, emotional processing and catharsis, recall of autobiographical memories subjectively related to illness origin, illness resignification, and perspective changes. This study suggests that the experience with ayahuasca may facilitate illness acceptance through an influence on the meanings of the illness, life, and death. These changes may favor a more balanced relationship with illness and treatment.

Psychotropic medication utilisation in adult cancer patients in China: A cross-sectional study based on national health insurance database

Background

Psychotropic medications are useful to treat psychiatric disorders which are frequently underdiagnosed and undertreated in cancer patients. Evidence on utilisation of psychotropic medications in cancer patients was absent in China. This study aimed to analyse the prevalence and the potential predictors of psychotropic medication use in adult cancer patients in China.

Methods

We analysed cross-sectional data from the China Health Insurance Association database in 2015-2017, which contained health care utilisation information for a national representative sample of basic medical insurance beneficiaries. Cancer patients aged above 18 were identified by International Classification of Disease 10th revision code C00-C97. Psychotropic medications were defined following the Anatomical Therapeutic Chemical codes: antipsychotics (N05A), anxiolytics (N05B), hypnotics and sedatives (N05C), and antidepressants (N06A, N06CA). We calculated the prevalence of psychotropic medication use in cancer patients, and applied multivariable logistic regression to identify its potential predictors.

Findings

A total of 260,364 adults with cancer were identified in the database, of which 48,111 (18•5%) were prescribed at least one psychotropic medication comprising antipsychotics (3763, 1•4%), anxiolytics (15,902, 6•1%), hypnotics and sedatives (37,040, 14•2%), and antidepressants (2379, 0•9%). Patients with solid tumours had higher prevalence of psychotropic medication use than patients with lymphoid and hematopoietic malignancies (e.g. female genital organs, adjusted odds ratio (OR)=2•25, 95%CI=2•09-2•44). The prevalence of psychotropic medication use in cancer patients in the Eastern region was significantly higher than those of cancer patients in the Western regions (OR=2•33, 95%CI=2•27-2•40). Compared with the Urban Rural Resident Basic Medical Insurance beneficiaries, cancer patients covered by the Urban Employee Basic Medical Insurance were more likely to use psychotropic medications (OR=1•18, 95%CI=1•15-1•20). Midazolam was the most frequently used psychotropic (21,728, 45•2%), and flupentixol-melitracen was the most commonly used antidepressant (1176, 2•4%) among all psychotropic medication users in the sample.

Interpretation

The prevalence of psychotropic medication use in Chinese adult cancer patients was inequitable. Further attention will be needed to be paid to the mental health of cancer patients in China.

An integrative collaborative care model for people with mental illness and physical comorbidities

BACKGROUND

Many individuals with mental health problems have comorbid physical conditions, or may present with substance/alcohol misuse or abuse issues. This results in complex treatment challenges that may not be adequately addressed by a model of care that is solely delivered by an individual clinician using a sole intervention. Mainstream pharmacotherapeutic treatment of mental health problems often have limited effectiveness in completely resolving symptoms, and may cause adverse side effects. Adjunctive treatment approaches, including nutraceuticals, lifestyle and behaviour change interventions, are widely used to assist with treatment of mental health problems. However, whilst these can be generally safer with fewer side effects, they have varying levels of evidentiary support. These circumstances warrant reframing the current treatment approach towards a more evidence-based integrative model which may better address the real-world challenges of psychiatric disorders and comorbid physical conditions. In essence, this means developing an integrative model of care which embodies an evidence-informed, personalized stepwise approach using both conventional pharmacological treatments alongside novel adjunctive treatments (where applicable) via the application of a collaborative care approach.

DISCUSSION

In order to inform this position, a brief review of findings on common patterns of comorbidity in mental illness is presented, followed by identification of limitations of conventional treatments, and potential applications of integrative medicine interventions. Advantages and challenges of integrative mental health care, collaborative models of care, review of research highlights of select integrative approaches, and comment on potential cost advantages are then discussed. We propose that a collaborative care model incorporating evidence-based integrative medicine interventions may more adequately address mental health problems with comorbid medical conditions. Robust research is now required of such a model, potentially within an integrative clinical practice.

Design, synthesis and neuropharmacological evaluation of new 2,4-disubstituted-1,5-benzodiazepines as CNS active agents

Benzodiazepines (BZDs) represent a class of privilege scaffold in the modern era of medicinal chemistry as CNS active agents and BZD based drugs are used to treat different psychotic disorders. Inspired from the therapeutic potential of BZDs as promising CNS active agents, in the present work three different series of 1,5-benzodiazepines bearing various substitutions at position 2 and 4 of the benzodiazepine core were synthesized by condensing different substituted chalcones with o-phenylenediamine in the presence of piperidine as a base catalyst. Structural characterization of title compounds was done by using various analytical techniques such as IR, NMR, elemental analysis and mass spectral data. All the synthesized compounds (9a-d, 10a-e and 11a-c) were subjected to in vivo neuropharmacological studies to evaluate their CNS depressant and antiepileptic activity. Results of in vivo evaluation data showed that analogue 11b exhibited potent CNS depressant activity which was comparable to the standard drug diazepam. Compounds 10b and 10c displayed significant antiepileptic activity however they were less potent than the standard drug phenobarbitone. Molecular docking studies were performed using MOE software to find the interaction pattern and binding mode at the GABAA receptor (PDB Id: 6HUP). The results of the docking studies were in good agreement with the observed in vivo activity and revealed the satisfactory binding mode of the compounds within the binding site of the protein. The docking scores for the most promising candidates 10c, 11b and Diazepam were found to be -9.18, -9.46 and -9.88, respectively. Further, the compounds showed compliance with the Lipinski's 'rule of five' and exhibited favourable drug-likeness scores. The identified leads can be explored further for the design and development of new BZD based psychotropic agents.

A potential role for psilocybin in the treatment of obsessive-compulsive disorder

The recent revivification of interest in the therapeutic use of psychedelics has had a particular focus on mood disorders and addiction, although there is reason to think these drugs may be effective more widely. After outlining pertinent aspects of psilocybin and obsessive-compulsive disorder (OCD), the current review summarizes the evidence indicating that there may be a role for psilocybin in the treatment of OCD, as well as highlighting a range of potential therapeutic mechanisms that reflect the action of psilocybin on brain function. Although the current evidence is limited, that multiple signals point in directions consistent with treatment potential, alongside the psychological and physiological safety of clinically administered psilocybin, support the expansion of research, both in animal models and in further randomized controlled trials, to properly investigate this potential.

Psychiatric comorbidities in cancer patients: acute interventions by the psychiatric consultation liaison service

AIM

The aim of this study was to explore the psychiatric comorbidities in cancer patients examined by the psychiatric consultation liaison services (CLP) in a general hospital. Furthermore, we intended to examine associations between certain cancers types and psychiatric disorders as well as to give an overview of the psychiatric treatments options that were recommended by the CLP.

METHODS

This retrospective analysis investigated 119 psychiatric consultations for cancer patients in a one year period. The assessment covered demographics and cancer diagnosis, psychiatric diagnosis and proceedings.

RESULTS

One third of all patients were treated for hematological cancer, followed by lung cancer. Depression was the most common psychiatric disorder. One third of all patients with hematological cancer were diagnosed with depression, followed by delirium. Inpatient psychiatric treatment and psychotherapy were most commonly recommended by the consultant psychiatrist. Furthermore, 80.2% of all patients received recommendations for medication with antidepressants.

CONCLUSION

Our data showed that the CLP provides an important service of detecting and initiating early and appropriate treatment for cancer patients with comorbid psychiatric disorders by directing patients to the relevant treatment procedure or facility.

Long-term follow-up of psilocybin-assisted psychotherapy for psychiatric and existential distress in patients with life-threatening cancer

BACKGROUND

A recently published randomized controlled trial compared single-dose psilocybin with single-dose niacin in conjunction with psychotherapy in participants with cancer-related psychiatric distress. Results suggested that psilocybin-assisted psychotherapy facilitated improvements in psychiatric and existential distress, quality of life, and spiritual well-being up to seven weeks prior to the crossover. At the 6.5-month follow-up, after the crossover, 60-80% of participants continued to meet criteria for clinically significant antidepressant or anxiolytic responses.

METHODS

The present study is a long-term within-subjects follow-up analysis of self-reported symptomatology involving a subset of participants that completed the parent trial. All 16 participants who were still alive were contacted, and 15 participants agreed to participate at an average of 3.2 and 4.5 years following psilocybin administration.

RESULTS

Reductions in anxiety, depression, hopelessness, demoralization, and death anxiety were sustained at the first and second follow-ups. Within-group effect sizes were large. At the second (4.5 year) follow-up approximately 60-80% of participants met criteria for clinically significant antidepressant or anxiolytic responses. Participants overwhelmingly (71-100%) attributed positive life changes to the psilocybin-assisted therapy experience and rated it among the most personally meaningful and spiritually significant experiences of their lives.

CONCLUSION

These findings suggest that psilocybin-assisted psychotherapy holds promise in promoting long-term relief from cancer-related psychiatric distress. Limited conclusions, however, can be drawn regarding the efficacy of this therapy due to the crossover design of the parent study. Nonetheless, the present study adds to the emerging literature base suggesting that psilocybin-facilitated therapy may enhance the psychological, emotional, and spiritual well-being of patients with life-threatening cancer.

Mental health care in oncology. Contemporary perspective on the psychosocial burden of cancer and evidence-based interventions

With cancer incidence increasing over time worldwide, attention to the burden of psychiatric and psychosocial consequences of the disease is now mandatory for both cancer and mental health care professionals. Psychiatric disorders have been shown to affect at least 30-35% of cancer patients during all phases of the disease trajectory, and differ in nature according to stage and type of cancer. Other clinically relevant distressing psychosocial and existential conditions (e.g. demoralisation, health anxiety, loss of meaning and existential distress) not included as 'disorders' in the usual diagnostic and nosological systems (i.e. meta-diagnostic conditions) have also been shown to be present in another 15-20% of cancer patients. In this editorial, we will present a summary of the extensive literature regarding the epidemiology of the several psychosocial disorders affecting cancer patients as a cause of distress and burden to be taken into consideration and addressed in cancer care through evidence-based intervention.

In vitro and in vivo anti-tumor effects of brexpiprazole, a newly-developed serotonin-dopamine activity modulator with an improved safety profile

From the perspective of psycho-oncology, antipsychotics are widely used for patients with cancer. Although some antipsychotic drugs have anti-tumor effects, these antipsychotic drugs are not applicable for cancer patients because of their severe side effects. Brexpiprazole, a novel serotonin-dopamine modulator with an improved side effect profile, was developed as a drug that is structurally and pharmacologically related to aripiprazole, which was reported to have anti-cancer effects. However, it remains unknown whether brexpiprazole has anti-cancer effects. In this study, we examined whether brexpiprazole has anti-tumor effects in cancer cells and cancer stem cells (CSCs) of glioblastoma, pancreatic cancer, and lung cancer. Brexpiprazole suppressed cell growth and induced cell death in the cancer cells and the CSCs, and decreased the CSC properties of the CSCs. Brexpiprazole did not exert any cytotoxic effects on non-cancer cells at the anti-cancer effect-inducing concentration. In the cancer cells and the CSCs, brexpiprazole reduced the expression of survivin, an anti-apoptotic protein, whose reduction sensitizes tumor cells to chemotherapeutic reagents. In the preclinical model in which pancreatic CSCs were subcutaneously implanted into nude mice, brexpiprazole suppressed tumor growth, in addition to reducing the expression of Sox2, a marker for CSCs, and survivin. This suggests that brexpiprazole is a promising antipsychotic drug with anti-tumor effects and an improved safety profile.

The Association Between Benzodiazepines and Survival in Patients With Cancer: A Systematic Review

CONTEXT

Patients with cancer often experience distressing symptoms such as anxiety or dyspnea, which can be managed with benzodiazepines; however, concerns regarding the impact of these drugs on survival may dissuade prescribing and compliance.

OBJECTIVES

We aimed to identify and appraise studies examining benzodiazepine use and survival in adults with cancer, to investigate the relationship and context of use.

METHODS

Systematic review of the international literature prepared according to preferred reporting items for systematic reviews. Comprehensive searches of the MEDLINE, Embase, PsycINFO, Cochrane Library, and AMED databases using medical subject heading and free-text search combinations with no date or language restrictions were undertook. Handsearching of references was conducted. Risk of bias of the included studies was assessed using Grading of Recommendations Assessment, Development, and Evaluation criteria.

RESULTS

Two thousand two hundred fifty-seven unique records were identified, with 18 meeting inclusion criteria, representing 4117 patients. All studies were very low quality. No study found an increase in mortality in association with benzodiazepine use, whereas two demonstrated an increase.

CONCLUSION

Existing evidence shows no association between benzodiazepine use in patients with cancer and decreased survival. None of the studies evaluated the association between benzodiazepine use and survival in earlier stages of cancer, and the quality of studies retrieved signifies a need for further robust studies to draw more definitive conclusions. Further investigation in patients with cancer using well-designed, high-quality research with survival as a primary outcome should be conducted.

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.

Psychiatric, behavioral, and cognitive disorders in patients with extracranial cancers

Patients with cancer may report neuropsychiatric abnormalities including cognitive impairment, behavioral disturbances, and psychiatric disorders that potentially worsen their quality of life, reduce their treatment response, and aggravate their overall prognosis. Neuropsychiatric disturbances have a different pathophysiology, including immuno-inflammatory and neuroendocrine mechanisms, as a consequence of oncologic treatments (chemo- and radio-therapy). Among clinicians involved in the management of such patients, psychiatrists need to pay particular attention in recognizing behavioral disturbances that arise in oncologic patients, and determining those that may be effectively treated with psychotropic medications, psychotherapeutic interventions, and an integration of them. Through the contribution of different clinicians actively involved in the management of oncological patients, the present review is ultimately aimed at updating psychiatrists in relation to the pathophysiological mechanisms responsible for the onset of cognitive, affective, and behavioral syndromes in these patients, along with epidemiologic and clinical considerations and therapeutic perspectives.

Therapeutic use of classic psychedelics to treat cancer-related psychiatric distress

Cancer is highly prevalent and one of the leading causes of global morbidity and mortality. Psychological and existential suffering is common in cancer patients, associated with poor psychiatric and medical outcomes. Promising early-phase clinical research (1960s to early 1970s) suggested a therapeutic signal for serotoninergic psychedelics (e.g. psilocybin, LSD) in treating cancer-related psychiatric distress. After several decades of quiescence, research on psychedelic-assisted therapy to treat psychiatric disorders in cancer patients has resumed within the last 2 decades in the US and Europe. This review article is based on a systematic search of clinical trials from 1960-2018 researching the therapeutic use of psychedelic treatment in patients with serious or terminal illnesses and related psychiatric illness. The search found 10 eligible clinical trials, with a total of 445 participants, with the vast majority of the patients having advanced or terminal cancer diagnoses. Six open label trials, published between 1964 and 1980 (n = 341), suggested that psychedelic therapy (mostly with LSD) may improve cancer-related depression, anxiety, and fear of death. Four RCTs trials were published between 2011 and 2016 (n = 104), mostly with psilocybin treatment (n = 92), and demonstrated that psychedelic-assisted treatment can produce rapid, robust, and sustained improvements in cancer-related psychological and existential distress.

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.

The burden of psychosocial morbidity related to cancer: patient and family issues

With cancer incidence increasing over time, attention to the burden of related psychiatric and psychosocial consequences of the disease and treatment is a major topic for both cancer patients and their caregivers. Among cancer patients, psychiatric (e.g. adjustment, anxiety, depressive disorders) and neuropsychiatric disorders (e.g. cognitive disorders secondary to treatment, delirium) have been shown to affect an average of 30-35% patients, with differences according to stage and type of cancer. Also other psychosocial syndromes (e.g. demoralization, health anxiety, irritable mood) not taken into account in usual nosological systems should be considered for their impact on the patient's quality-of-life. Also, it has been repeatedly reported that psychological distress reverberates substantially throughout the nuclear family, and that a family approach is necessary in cancer care, with the caregiver-patient dyad as a unit to be the focus and direction of assessment and intervention. In this review the most significant psychosocial disorders causing burden for cancer patients and their caregivers are examined, and the main methods of assessment for more proper referral and treatment are summarized.

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: Diagnostic Issues and Intervention. A Critical Review

Depressive spectrum disorders, including major depression, persistent depression, minor and sub-syndromal depression, and other forms of depressive conditions, such as demoralization, are among the most common psychiatric consequences of cancer patients, affecting up to 60% of patients. In spite of the negative effects and the burden for cancer patients and their families, these disorders often remain under-recognized and undertreated. The present review aims at summarizing the relevant data concerning the diagnostic challenges within the depressive spectrum disorders among cancer patients. Also, the most relevant data relative to integrated intervention, including psychopharmacological and psychosocial treatment, for depression in cancer patients are critically evaluated. It is mandatory that health care professionals working in oncology (e.g., oncologists, surgeons, radiation oncologists, primary care physicians, nurses, social workers, psychologists) receive training in the diagnosis and integrated management of the different types of disorder within the spectrum of clinical depression.

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.

Rapid and sustained symptom reduction following psilocybin treatment for anxiety and depression in patients with life-threatening cancer: a randomized controlled trial

BACKGROUND

Clinically significant anxiety and depression are common in patients with cancer, and are associated with poor psychiatric and medical outcomes. Historical and recent research suggests a role for psilocybin to treat cancer-related anxiety and depression.

METHODS

In this double-blind, placebo-controlled, crossover trial, 29 patients with cancer-related anxiety and depression were randomly assigned and received treatment with single-dose psilocybin (0.3 mg/kg) or niacin, both in conjunction with psychotherapy. The primary outcomes were anxiety and depression assessed between groups prior to the crossover at 7 weeks.

RESULTS

Prior to the crossover, psilocybin produced immediate, substantial, and sustained improvements in anxiety and depression and led to decreases in cancer-related demoralization and hopelessness, improved spiritual wellbeing, and increased quality of life. At the 6.5-month follow-up, psilocybin was associated with enduring anxiolytic and anti-depressant effects (approximately 60-80% of participants continued with clinically significant reductions in depression or anxiety), sustained benefits in existential distress and quality of life, as well as improved attitudes towards death. The psilocybin-induced mystical experience mediated the therapeutic effect of psilocybin on anxiety and depression.

CONCLUSIONS

In conjunction with psychotherapy, single moderate-dose psilocybin produced rapid, robust and enduring anxiolytic and anti-depressant effects in patients with cancer-related psychological distress.

Psilocybin produces substantial and sustained decreases in depression and anxiety in patients with life-threatening cancer: A randomized double-blind trial

Cancer patients often develop chronic, clinically significant symptoms of depression and anxiety. Previous studies suggest that psilocybin may decrease depression and anxiety in cancer patients. The effects of psilocybin were studied in 51 cancer patients with life-threatening diagnoses and symptoms of depression and/or anxiety. This randomized, double-blind, cross-over trial investigated the effects of a very low (placebo-like) dose (1 or 3 mg/70 kg) vs. a high dose (22 or 30 mg/70 kg) of psilocybin administered in counterbalanced sequence with 5 weeks between sessions and a 6-month follow-up. Instructions to participants and staff minimized expectancy effects. Participants, staff, and community observers rated participant moods, attitudes, and behaviors throughout the study. High-dose psilocybin produced large decreases in clinician- and self-rated measures of depressed mood and anxiety, along with increases in quality of life, life meaning, and optimism, and decreases in death anxiety. At 6-month follow-up, these changes were sustained, with about 80% of participants continuing to show clinically significant decreases in depressed mood and anxiety. Participants attributed improvements in attitudes about life/self, mood, relationships, and spirituality to the high-dose experience, with >80% endorsing moderately or greater increased well-being/life satisfaction. Community observer ratings showed corresponding changes. Mystical-type psilocybin experience on session day mediated the effect of psilocybin dose on therapeutic outcomes.

Use of Medications for Treating Anxiety and Depression in Cancer Survivors in the United States

Purpose This study used population-based data to estimate the percentage of cancer survivors in the United States reporting current medication use for anxiety and depression and to characterize the survivors taking this type of medication. Rates of medication use in cancer survivors were compared with rates in the general population. Methods We analyzed data from the National Health Interview Survey, years 2010 to 2013, identifying cancer survivors (n = 3,184) and adults with no history of cancer (n = 44,997) who completed both the Sample Adult Core Questionnaire and the Adult Functioning and Disability Supplement. Results Compared with adults with no history of cancer, cancer survivors were significantly more likely to report taking medication for anxiety (16.8% v 8.6%, P < .001), depression (14.1% v 7.8%, P < .001), and one or both of these conditions combined (19.1% v 10.4%, P < .001), indicating that an estimated 2.5 million cancer survivors were taking medication for anxiety or depression in the United States at that time. Survivor characteristics associated with higher rates of medication use for anxiety included being younger than 65 years old, female, and non-Hispanic white, and having public insurance, a usual source of medical care, and multiple chronic health conditions. Survivor characteristics associated with medication use for depression were largely consistent with those for anxiety, with the exceptions that insurance status was not significant, whereas being widowed/divorced/separated was associated with more use. Conclusion Cancer survivors in the United States reported medication use for anxiety and depression at rates nearly two times those reported by the general public, likely a reflection of greater emotional and physical burdens from cancer or its treatment.

Efficacy and acceptability of antidepressants on the continuum of depressive experiences in patients with cancer: Systematic review and meta-analysis

BACKGROUND

Patients with cancer are particularly vulnerable to depressive experiences, ranging from severe emotional reactions to proper depressive syndromes, including major depression. These experiences may deeply affect the course and outcome of the disease. The aim of this study was to assess the efficacy acceptability of antidepressants on the continuum of depressive experiences in patients suffering from cancer.

METHODS

MEDLINE, EMBASE, PsycINFO, CENTRAL, as well as websites of regulatory agencies, clinical trial repositories and pharmaceutical companies, were systematically searched for published and unpublished randomised trials assessing the efficacy of antidepressants versus placebo in patients with cancer. Efficacy of antidepressants at the end of the study was the primary outcome. The review protocol was registered with PROSPERO (CRD42014013440).

RESULTS

A total of 19 studies contributed to the analysis. Antidepressants (particularly the selective serotonin-reuptake inhibitors and mianserin) were more effective than placebo in relieving depressive experiences in both patients with major depression or depressive symptoms (standardised mean difference -0.596, 95% confidence interval -1.041 to -0.150), as well as in patients with other cancer-related distressing symptoms (standardised mean difference -0.229, 95% confidence interval -0.419 to -0.039). We found evidence that efficacy was positively associated with length of treatment. No differences between antidepressants and placebo were found in terms of overall acceptability.

CONCLUSIONS

Antidepressants should be considered as one treatment option for relieving the burden of depressive experiences in patients with cancer.

Comparison of psychotropic prescriptions between oncology and cardiology inpatients: result from a pharmacy database in a teaching hospital in Malaysia

OBJECTIVE

To examine the prescription rates in cancer patients of three common psychotropic drugs: anxiolytic/ hypnotic, antidepressant and antipsychotic.

MATERIALS AND METHODS

In this retrospective cohort study, data were extracted from the pharmacy database of University Malaya Medical Center (UMMC) responsible for dispensing records of patients stored in the pharmacy's Medication Management and Use System (Ascribe). We analyzed the use of psychotropics in patients from the oncology ward and cardiology from 2008 to 2012. Odds ratios (ORs) were adjusted for age, gender and ethnicity.

RESULTS

A total of 3,345 oncology patients and 8,980 cardiology patients were included. Oncology patients were significantly more often prescribed psychotropic drugs (adjusted OR: anxiolytic/hypnotic=5.55 (CI: 4.64-6.63); antidepressants=6.08 (CI: 4.83-7.64) and antipsychotics=5.41 (CI: 4.17-7.02). Non-Malay female cancer patients were at significantly higher risk of anxiolytic/hypnotic use.

CONCLUSIONS

Psychotropic drugs prescription is common in cancer patients. Anxiolytic/hypnotic prescription rates are significantly higher in non-Malay female patients in Malaysia.

Management of delirium in palliative care: a review

Delirium is a complex but common disorder in palliative care with a prevalence between 13 and 88 % but a particular frequency at the end of life (terminal delirium). By reviewing the most relevant studies (MEDLINE, EMBASE, PsycLit, PsycInfo, Cochrane Library), a correct assessment to make the diagnosis (e.g., DSM-5, delirium assessment tools), the identification of the possible etiological factors, and the application of multicomponent and integrated interventions were reported as the correct steps to effectively manage delirium in palliative care. In terms of medications, both conventional (e.g., haloperidol) and atypical antipsychotics (e.g., olanzapine, risperidone, quetiapine, aripiprazole) were shown to be equally effective in the treatment of delirium. No recommendation was possible in palliative care regarding the use of other drugs (e.g., α-2 receptors agonists, psychostimulants, cholinesterase inhibitors, melatonergic drugs). Non-pharmacological interventions (e.g., behavioral and educational) were also shown to be important in the management of delirium. More research is necessary to clarify how to more thoroughly manage delirium in palliative care.

Bridging the gap between education and appropriate use of benzodiazepines in psychiatric clinical practice

More than half a century after their discovery, benzodiazepines (BDZs) still represent one of the largest and most widely prescribed groups of psychotropic compounds, not only in clinical psychiatry but also in the entire medical field. Over the last two decades, however, there has been an increased focus on the development of antidepressants and antipsychotics on the part of the pharmaceutical industry, clinicians, and researchers, with a reduced interest in BDZs, in spite of their widespread clinical use. As a consequence, many psychiatric residents, medical students, nurses, and other mental health professionals might receive poor academic teaching and training regarding these agents, and have the false impression that BDZs represent an outdated chapter in clinical psychopharmacology. However, recent advances in the field, including findings concerning epidemiology, addiction risk, and drug interactions, as well as the introduction of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition with related diagnostic changes, strongly encourage an updated appraisal of the use of BDZs in clinical practice. During a recent thematic event convened with the aim of approaching this topic in a critical manner, a group of young Italian psychiatrists attempted to highlight possible flaws in current teaching pathways, identify the main clinical pros and cons regarding current use of BDZs in clinical practice, and provide an updated overview of their use across specific clinical areas and patient populations. The main results are presented and discussed in this review.

Psychopharmacology in cancer

Depression, anxiety, delirium, and other psychiatric symptoms are highly prevalent in the cancer setting, and pharmacological intervention is an important component in the overall psychosocial care of the patient. Psychopharmacology is also used as a primary or adjuvant treatment for the management of cancer-related symptoms stemming from the disease itself and/or its treatment, including sleep disturbance, loss of appetite, neuropathic pain, nausea, fatigue, and hot flashes. Psychiatrists, oncologists, and palliative care physicians working as members of a multidisciplinary team have the opportunity to target multiple symptoms that negatively affect a patient's quality of life with the strategic use of psychotropic medications when deemed appropriate. This article aims to review the indications for use of antidepressants, psychostimulants, anxiolytics, antipsychotics, and mood stabilizers in oncology. An updated review of the relevant literature is discussed and referenced in each section.
