Stage at diagnosis and survival in patients with cancer and a pre-existing mental illness: a meta-analysis

Disparities in cancer care in individuals with severe mental illness: A narrative review

Individuals with severe mental illness (SMI) have higher mortality rates from cancer than individuals without SMI. The aim of this paper is to highlight these disparities in cancer care in individuals with SMI and suggest potential solutions. We conducted a narrative review of published papers, focusing on mortality, incidence, behavioral and provider risk factors, screening, diagnosis, treatment, and palliative care among individuals with SMI and cancer. The literature does not provide a clear consensus on whether a difference in cancer incidence exists among individuals with SMI compared to the general population. However, it is evident that individuals with SMI have higher mortality from cancer. Factors such as increased cancer related risk behavior, mental health stigma, and difficulty accessing cancer care contribute to this mortality difference. The literature also indicates lower screening rates, delayed and improper diagnosis and treatment, as well as inadequate clinical trial enrollment in individuals with SMI. While the literature is inconclusive regarding disparities in palliative care, we outline key concepts to provide the best possible end of life care to this population. We also summarize strategies to address disparities at the screening, diagnostic, and treatment levels and describe general strategic approaches to improve cancer care in individuals with SMI. We highlight patient-related, physician-related, and healthcare/systems-related factors leading to disparities in cancer care in individuals with SMI. Future research must examine the effectiveness of proposed solutions to guide evidence-based practices.

The Effect of Oncology Nurse Navigation on Mental Health in Patients with Cancer in Taiwan: A Randomized Controlled Clinical Trial

In this study, we investigated the prevalence of mental health problems among patients with cancer and whether oncology nurse navigation improved their mental health outcomes and medical experience. In this randomized controlled clinical trial, we recruited 128 outpatients with cancer via purposive sampling from a teaching hospital in northern Taiwan. Participants were randomly assigned to the navigation group (N = 61) or the usual care group (N = 67). Data were collected from January 2019 to July 2020 using questionnaires, including the self-reported Distress Thermometer, Hospital Anxiety and Depression Scale, Demoralization Scale, and Patient Assessment of Chronic Illness Care. Data were collected at baseline and after three and six months of the intervention. Descriptive and analytical statistical analyses were performed. The prevalence rates of anxiety, depression, distress, and demoralization were 17.9%, 15.7%, 29.7%, and 29.7%, respectively. After three months, the participants in the navigation group exhibited significantly reduced levels of anxiety, demoralization, and emotional distress (reduced by 92%, 75%, and 58%, respectively) and reported a better medical experience (odds ratio = 1.40) than those in the usual care group.

Treatment and Mortality Following Cancer Diagnosis Among People With Non-affective Psychotic Disorders in Ontario, Canada: A Retrospective Cohort Study

BACKGROUND AND HYPOTHESIS

People with psychotic disorders have a higher risk of mortality following cancer diagnosis, compared to people without psychosis. The extent to which this disparity is influenced by differences in cancer-related treatment is currently unknown. We hypothesized that, following a cancer diagnosis, people with psychotic disorders were less likely to receive treatment and were at higher risk of death than those without psychosis.

STUDY DESIGN

We constructed a retrospective cohort of cases of non-affective psychotic disorder (NAPD) and a general population comparison group, using Ontario Health (OH) administrative data. We identified cases of all cancers diagnosed between 1995 and 2019 and obtained information on cancer-related treatment and mortality. Cox proportional hazards models were used to compare the probability of having a consultation with an oncologist and receiving cancer-related treatment, adjusting for tumor site and stage. We also compared the rate of all-cause and cancer-related mortality between the two groups, adjusting for tumor site.

STUDY RESULTS

Our analytic sample included 24 944 people diagnosed with any cancer. People with NAPD were less likely to receive treatment than people without psychosis (HR = 0.87, 95% CI = 0.82, 0.91). In addition, people with NAPD had a greater risk of death from any cause (HR = 1.68, 95% CI = 1.60, 1.76), compared to people without NAPD.

CONCLUSIONS

The lower likelihood of receiving cancer treatment reflects disparities in accessing cancer care for people with psychotic disorders, which may partially explain the higher mortality risk following cancer diagnosis. Future research should explore mediating factors in this relationship to identify targets for reducing health disparities.

Somatic health according to people with severe mental disease

OBJECTIVES

Patients with schizophrenia have a 15- to 20-year shorter life expectancy compared with the general population. The aim of this study was to explore these patients' perception of their physical health.

METHODS

A patient reported outcomes measure (PROM) has been developed by patients with severe mental disease. This survey had to better capture undetected, under-rated and non-prioritized physical domains by traditional routine clinical scales that are important for people who live with mental health disease. These patients have tested the applicability of this PROM with peers with severe mental disease in medical, social and community-based centers from Hauts-de-France.

RESULTS

Two and a half years have been required to develop this PROM, to test its applicability to patients with severe mental disease and to analyze the results. The study process has been slowed by the sanitary context induced by the COVID-19 pandemic. Thirty-two questionnaires have been collected by the participants. Despite this low number of data, participants have been satisfied by the results and their experience. The results show that people with severe mental disease consider physical health as a major concern, notably pain and somatic diseases. External factors (such as accessibility to health care and medication) and internal factors (such as self-esteem, cognitive and negative symptoms, sleep, alimentation, and substance use) have been identified as barriers for physical health.

CONCLUSIONS

These results support the development of PROMs highlighting personal experience of people with severe mental disease. The data obtained thanks to these measures will allow to build programs to help them to cope with barriers for physical health.

Overall and Cervical Cancer Survival in Patients With and Without Mental Disorders

Importance

Individuals with a mental disorder experience substantial health disparity and are less likely to participate in cervical screening and human papillomavirus vaccination. Additionally, this population may benefit less from tertiary cancer prevention.

Objective

To compare clinical characteristics and survival patterns between patients with cervical cancer with and without a preexisting diagnosis of a mental disorder at the time of cervical cancer diagnosis.

Design, Setting, and Participants

This cohort study obtained data from Swedish population-based (Swedish Cancer Register, Swedish Cause of Death Register, Swedish Total Population Register, Swedish Patient Register, and Swedish Longitudinal Integration Database for Health Insurance and Labor Market Studies) and quality registries (Swedish Quality Register of Gynecologic Cancer and Swedish National Cervical Screening Register) on patients with cervical cancer. Patients who were included in the analysis were identified using the Swedish Cancer Register and were diagnosed with cervical cancer between 1978 and 2018. The Swedish Patient Register was used to identify patients with mental disorders using codes from the International Classification of Diseases, Eighth Revision and Ninth Revision and the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision. Because data on clinical characteristics at the time of cancer diagnosis were available for only for part of the study population, 2 patient groups were created: those with cervical cancer diagnosed from 2002 to 2016 and all patients diagnosed with cervical cancer (1978-2018). Data analyses were carried out between March and September 2022.

Exposure

Clinical diagnoses of a mental disorder, including substance abuse, psychotic disorders, depression, anxiety, stress-related disorders, attention-deficit/hyperactivity disorder, autism, and intellectual disability, prior to cervical cancer.

Main Outcomes and Measures

Death due to any cause or due to cervical cancer as ascertained from the Swedish Cause of Death Register.

Results

The sample included 20 177 females (mean [SD] age, 53.4 [17.7] years) diagnosed with cervical cancer from 1978 to 2018. In a subgroup of 6725 females (mean [SD] age, 52.2 [18.0] years) with cervical cancer diagnosed from 2002 to 2016, 893 (13.3%) had a preexisting diagnosis of a mental disorder. Compared with patients with no preexisting mental disorder diagnosis, those with a preexisting mental disorder had a higher risk of death due to any cause (hazard ratio [HR], 1.32; 95% CI, 1.17-1.48) and due to cervical cancer (HR, 1.23; 95% CI, 1.07-1.42). These risks were lower after adjustment for cancer characteristics at the time of cancer diagnosis (death due to any cause: HR, 1.19 [95% CI, 1.06-1.34] and death due to cervical cancer: HR, 1.12 [95% CI, 0.97-1.30]). Risk of death was higher for patients with substance abuse, psychotic disorders, or mental disorders requiring inpatient care. Among patients with cervical cancer diagnosed from 1978 to 2018, the estimated 5-year survival improved continuously during the study period regardless of preexisting diagnosis of a mental disorder status. For example, in 2018, the estimated 5-year overall survival proportion was 0.66 (95% CI, 0.60-0.71) and 0.74 (95% CI, 0.72-0.76) for patients with and without a preexisting diagnosis of a mental disorder, respectively.

Conclusions and Relevance

Findings of this cohort study suggest that patients with cervical cancer and a preexisting diagnosis of a mental disorder have worse overall and cervical cancer-specific survival than patients without a preexisting mental disorder diagnosis, which may be partly attributable to cancer and sociodemographic characteristics at diagnosis. Hence, individuals with mental disorders deserve special attention in the tertiary prevention of cervical cancer.

Experiences of Everyday Life among Individuals with Co-Existence of Serious Mental Illness and Cancer-A Qualitative Systematic Literature Review

Daily life with severe mental health (SMI) and cancer comorbidity entails multiple challenges. The study aims to explore everyday life experiences among individuals with SMI and cancer comorbidity from the perspectives of patients, significant others, and involved healthcare professionals. The study is registered in PROSPERO (CRD42021259604). A qualitative systematic review was conducted through searches in the databases MEDLINE, CINAHL, PsychInfo, and Web of Sciences (last search 14 February 2023). Inclusion criteria were empirical qualitative research studies investigating experiences of healthcare and everyday life among persons living with SMI and who were subsequently diagnosed with cancer from the perspective of the individuals themselves, their significant others, and healthcare professionals involved in their care. Exclusion criteria: Literature reviews, quantitative studies, intervention studies, quantitative parts of mix-methods studies, non-English languages, persons <18 years, dementia/learning disabilities, diagnosed with anxiety/depression as a consequence of cancer. Seven articles, published between January 2011 and February 2023, were included and analysed through a thematic analysis. The PRISMA 2020 checklist guided the study. The results were presented in four themes: 'Navigating between different worlds and logics', 'Decision-making capacity depending on the assessor', 'Cancer must give way to severe mental illness or vice versa', and 'Significant others as a safety net'. Research about the everyday lives of persons with SMI and cancer comorbidities from patients' and relatives' perspectives is lacking and thus called for.

Impact of pre-existing mental health disorders on the receipt of guideline recommended cancer treatments: A systematic review

OBJECTIVE

Disparities in cancer outcomes for individuals with pre-existing mental health disorders have already been identified, particularly for cancer screening and mortality. We aimed to systematically review the influence on the time from cancer diagnosis to cancer treatment, treatment adherence, and differences in receipt of guideline recommended cancer treatment.

METHODS

We included international studies published in English from 1 January 1995 to 23 May 2022 by searching MEDLINE, Embase, and APA PsycInfo.

RESULTS

This review identified 29 studies with 27 being published in the past decade. Most studies focused on breast, non-small cell lung and colorectal cancer and were of high or medium quality as assessed by the Newcastle Ottawa Scale. All studies were from high-income countries, and mostly included patients enrolled in national health insurance systems. Five assessed the impact on treatment delay or adherence, and 25 focused on the receipt of guideline recommended treatment. 20/25 studies demonstrated evidence that patients with pre-existing mental health disorders were less likely to receive guideline recommended therapies such as surgery or radiotherapy. In addition, there was a greater likelihood of receiving less intensive or modified treatment including systemic therapy.

CONCLUSIONS

Across different cancer types and treatment modalities there is evidence of a clear disparity in the receipt of guideline recommended cancer treatment for patients with pre-existing mental health disorders. The effect of pre-existing mental health disorders on treatment delay or adherence is under-researched. Future research needs to include low- and middle-income countries as well as qualitative investigations to understand the reasons for disparities in cancer treatment.

Health and healthcare equity within the Canadian cancer care sector: a rapid scoping review

BACKGROUND

Despite a publicly-funded healthcare system, alarming cancer-related health and healthcare inequities persist in Canada. However, it remains unclear how equity is being understood and taken up within the Canadian cancer context. Our objective was to identify how health and healthcare equity are being discussed as goals or aims within the cancer care sector in Canada.

METHODS

A rapid scoping review was conducted; five biomedical databases, 30 multidisciplinary websites, and Google were searched. We included English-language documents published between 2008 and 2021 that discussed health or healthcare equity in the Canadian cancer context.

RESULTS

Of 3860 identified documents, 83 were included for full-text analysis. The prevalence of published and grey equity-oriented literature has increased over time (2008-2014 [n = 20]; 2015-2021 [n = 62]). Only 25% of documents (n = 21) included a definition of health equity. Concepts such as inequity, inequality and disparity were frequently used interchangeably, resulting in conceptual muddling. Only 43% of documents (n = 36) included an explicit health equity goal. Although a suite of actions were described across the cancer control continuum to address equity goals, most were framed as recommendations rather than direct interventions.

CONCLUSION

Health and healthcare equity is a growing priority in the cancer care sector; however, conceptual clarity is needed to guide the development of robust equity goals, and the development of sustainable, measurable actions that redress inequities across the cancer control continuum. If we are to advance health and healthcare equity in the cancer care sector, a coordinated and integrated approach will be required to enact transformative and meaningful change.

Colorectal cancer treatment in people with severe mental illness: a systematic review and meta-analysis

AIMS

People with severe mental illness (SMI) have a greater risk of dying from colorectal cancer (CRC), even though the incidence is lower or similar to that of the general population This pattern is unlikely to be solely explained by lifestyle factors, while the role of differences in cancer healthcare access or treatment is uncertain.

METHODS

We undertook a systematic review and meta-analysis on access to guideline-appropriate care following CRC diagnosis in people with SMI including the receipt of surgery, chemo- or radiotherapy. We searched for full-text articles indexed by PubMed, EMBASE, PsychInfo and CINAHL that compared CRC treatment in those with and without pre-existing SMI (schizophrenia, schizoaffective, bipolar and major affective disorders). Designs included cohort or population-based case-control designs.

RESULTS

There were ten studies (sample size = 3501-591 561). People with SMI had a reduced likelihood of surgery (RR = 0.90, 95% CI 0.92-0.97; p = 0.005; k = 4). Meta-analyses were not possible for the other outcomes but in results from individual studies, people with SMI were less likely to receive radiotherapy, chemotherapy or sphincter-sparing procedures. The disparity in care was greatest for those who had been psychiatric inpatients.

CONCLUSIONS

People with SMI, including both psychotic and affective disorders, receive less CRC care than the general population. This might contribute to higher case-fatality rates for an illness where the incidence is no higher than that of the general population. The reasons for this require further investigation, as does the extent to which differences in treatment access or quality contribute to excess CRC mortality in people with SMI.

Incidence of psychiatric illness in patients with neuroendocrine tumors: a comparative population-based analysis

PURPOSE

Diversion of tryptophan to tumoral hormonal production has been suggested to result in psychiatric illnesses in neuroendocrine tumors (NET). We measured the occurrence of psychiatric illness after NET diagnosis and compare it to colon cancer (CC).

METHODS

We conducted a population-based retrospective cohort study. Adults with NET were matched 1:1 to CC (2000-2019). Psychiatric illness was defined by mental health diagnoses and mental health care use after a cancer diagnosis, categorized as severe, other, and none. Cumulative incidence functions accounted for death as a competing risk.

RESULTS

A total of 11,223 NETs were matched to CC controls. Five-year cumulative incidences of severe psychiatric illness for NETs vs. CC was 7.7% (95%CI 7.2-8.2%) vs 7.6% (95%CI 7.2-8.2%) (p = 0.50), and that of other psychiatric illness was 32.9% (95%CI 32.0-33.9%) vs 31.6% (95%CI 30.8-32.6%) (p = 0.005). In small bowel and lung NETs, 5-year cumulative incidences of severe (8.1% [95%CI 7.3-8.9%] vs. 7.0% [95%CI 6.3-7.8%]; p = 0.01) and other psychiatric illness (34.7% [95%CI 33.3-36.1%] vs. 31.1% [95%CI 29.7-32.5%]; p < 0.01) were higher than for matched CC. The same was observed for serotonin-producing NETs for both severe (7.9% [95%CI 6.5-9.4%] vs. 6.8% [95%CI 5.5-8.2%]; p = 0.02) and other psychiatric illness (35.4% [95%CI 32.8-38.1%] vs. 31.9% [95%CI 29.3-34.4%]; p = 0.02).

CONCLUSIONS

In all NETs, there was no difference observed in the incidence of psychiatric illness compared to CC. For sub-groups of small bowel and lung NETs and of serotonin-producing NETs, the incidence of psychiatric illness was higher than for CC. These data suggest a signal towards a relationship between those sub-groups of NETs and psychiatric illness.

Mental Health Morbidities and Time to Cancer Diagnosis Among Adults With Colon Cancer in England

Importance

Mental health morbidity (MHM) in patients presenting with possible cancer symptoms may be associated with prediagnostic care and time to cancer diagnosis.

Objective

To compare the length of intervals to cancer diagnosis by preexisting MHM status in patients who presented with symptoms of as-yet-undiagnosed colon cancer and evaluate their risk of emergency cancer diagnosis.

Design, Setting, and Participants

This cohort study was conducted using linked primary care data obtained from the population-based Clinical Practice Research Datalink, which includes primary care practices in England, linked to cancer registry and hospital data. Included participants were 3766 patients diagnosed with colon cancer between 2011 and 2015 presenting with cancer-relevant symptoms up to 24 months before their diagnosis. Data analysis was performed in January 2021 to April 2022.

Exposures

Mental health conditions recorded in primary care before cancer diagnosis, including anxiety, depression, schizophrenia, bipolar disorder, alcohol addiction, anorexia, and bulimia.

Main Outcomes and Measures

Fast-track (also termed 2-week wait) specialist referral for investigations, time to colonoscopy and cancer diagnosis, and risk of emergency cancer diagnosis.

Results

Among 3766 patients with colon cancer (median [IQR] age, 75 [65-82] years; 1911 [50.7%] women ), 623 patients [16.5%] had preexisting MHM recorded in primary care the year before cancer diagnosis, including 562 patients (14.9%) with preexisting anxiety or depression (accounting for 90.2% of patients with preexisting MHM) and 61 patients (1.6%) with other MHM; 3143 patients (83.5%) did not have MHM. Patients with MHM had records of red-flag symptoms or signs (ie, rectal bleeding, change in bowel habit, or anemia) in the 24 months before cancer diagnosis in a smaller proportion compared with patients without MHM (308 patients [49.4%] vs 1807 patients [57.5%]; P < .001). Even when red-flag symptoms were recorded, patients with MHM had lower odds of fast-track specialist referral (adjusted odds ratio [OR] = 0.72; 95% CI, 0.55-0.94; P = .01). Among 2115 patients with red-flag symptoms or signs, 308 patients with MHM experienced a more than 2-fold longer median (IQR) time to cancer diagnosis (326 [75-552] days vs 133 [47-422] days) and higher odds of emergency diagnosis (90 patients [29.2%] vs 327 patients [18.1%]; adjusted OR = 1.63; 95% CI, 1.23-2.24; P < .001) compared with 1807 patients without MHM.

Conclusions and Relevance

This study found that patients with MHM experienced large and prognostically consequential disparities in diagnostic care before a colon cancer diagnosis. These findings suggest that appropriate pathways and follow-up strategies after symptomatic presentation are needed for earlier cancer diagnoses and improved health outcomes in this large patient group.

Mortality after the 9/11 terrorist attacks among world trade center health registry enrollees with cancer

BACKGROUND

While several studies have reported the association between 9/11 exposure and cancer risk, cancer survival has not been well studied in the World Trade Center (WTC) exposed population. We examined associations of 9/11-related exposures with mortality in WTC Health Registry enrollees diagnosed with cancer before and after 9/11/2001.

PATIENTS AND METHODS

This is a longitudinal cohort study of 5061 enrollees with a first-ever primary invasive cancer diagnosis between 1995 and 2015 and followed through 2016. Based on the timing of first cancer diagnosis, pre-9/11 (n = 634) and post-9/11 (n = 4427) cancer groups were examined separately. 9/11-related exposures included witnessing traumatic events, injury on 9/11, and 9/11-related post-traumatic stress disorder (PTSD). Associations of exposures with all-cause mortality were examined using Cox proportional hazards regression. In the post-9/11 group, cancer-specific mortality was evaluated by enrollee group (WTC rescue/recovery workers vs. non-workers) using Fine and Gray's proportional sub-distribution hazard models, adjusting for baseline covariates, tumor characteristics, and treatment.

RESULTS

In the pre-9/11 group, 9/11-related exposures were not associated with all-cause mortality. In the post-9/11 group, increased risk of all-cause mortality was associated with PTSD (adjusted HR = 1.35; 95% CI = 1.11-1.65), but not with injury or witnessing traumatic events. Cancer-specific mortality was not statistically significantly associated with 9/11-related exposures. In rescue/recovery workers, increased non-cancer mortality risk was associated with PTSD (aHR = 2.13, 95% CI = 1.13-4.00) and witnessing ≥3 traumatic events (aHR = 2.00, 95% CI = 1.13-3.55).

CONCLUSIONS

We did not observe associations between 9/11-related exposures and cancer-specific mortality. Similar to findings in the non-cancer WTC exposed population, PTSD was associated with increased risk of all-cause mortality in cancer patients.

Biopsychosocial factors associated with complications in patients with frostbite

Cold weather injuries can be devastating and life changing. Biopsychosocial factors such as homelessness and mental illness (especially substance use disorders [SUDs]) are known risk factors for incurring frostbite. Based on clinical experience in an urban level 1 trauma center, we hypothesized that complications following frostbite injury would be influenced by homelessness, SUDs, and other forms of mental illness. The aim of this study was to examine the relationship between biopsychosocial factors and both amputations and unplanned hospital readmissions after cold injuries. Patients admitted with a diagnosis of frostbite between the winters of 2009 and 2018 were included in this retrospective cohort study. Descriptive statistics and multivariable regression assessed factors associated with outcomes of interest. Of the 148 patients in the study, 40 had unplanned readmissions within 1 year. Readmitted patients were significantly less likely to have a stable living situation (48.7% vs 75.0%, P = .005) and more likely to have an SUD (85.0% vs 60.2%, P = .005) or other psychiatric disorder (70.0% vs 50.9%, P = .042). Homelessness and SUDs were independent predictors of unplanned readmission. Overall, 18% of frostbite injuries resulted in amputation. Any history of drug and/or alcohol use independently predicted amputations. The study results suggest that additional hospital and community resources may need to be marshaled to prevent vulnerable patients with biopsychosocial risk factors from having complications after frostbite. Complications place a high downstream burden on healthcare systems. Clinicians caring for frostbite patients with comorbid conditions can use these findings to inform care and discharge decisions.

Cancer incidence and stage at diagnosis among people with psychotic disorders: Systematic review and meta-analysis

Research regarding the incidence of cancer among people with psychotic disorders relative to the general population is equivocal, although the evidence suggests that they have more advanced stage cancer at diagnosis. We conducted a systematic review and meta-analysis to examine the incidence and stage at diagnosis of cancer among people with, relative to those without, psychotic disorders. We searched the MEDLINE, EMBASE, PsycINFO, and CINAHL databases. Articles were included if they reported the incidence and/or stage at diagnosis of cancer in people with psychotic disorders. Random effects meta-analyses were used to determine risk of cancer and odds of advanced stage cancer at diagnosis in people with psychosis, relative to those without psychotic disorders. A total of 40 articles were included in the review, of which, 31 were included in the meta-analyses. The pooled age-adjusted risk ratio for all cancers in people with psychotic disorders was 1.08 (95% CI: 1.01-1.15), relative to those without psychotic disorders, with significant heterogeneity by cancer site. People with psychotic disorders had a higher incidence of breast, oesophageal, colorectal, testicular, uterine, and cervical cancer, and a lower incidence of skin, prostate, and thyroid cancer. People with psychotic disorders also had 22% higher (95% CI: 2-46%) odds of metastases at diagnosis, compared to those without psychotic disorders. Our systematic review found a significant difference in overall cancer incidence among people diagnosed with psychotic disorders and people with psychotic disorders were more likely to present with advanced stage cancer at diagnosis. This finding may reflect a need for improved access to and uptake of cancer screening for patients diagnosed with psychotic disorders.

Opioid Therapy in Cancer Patients and Survivors at Risk of Addiction, Misuse or Complex Dependency

A clinical conundrum can occur when a patient with active opioid use disorder (OUD) or at elevated risk for the condition presents with cancer and related painful symptoms. Despite earlier beliefs that cancer patients were relatively unaffected by opioid misuse, it appears that cancer patients have similar risks as the general population for OUD but are more likely to need and take opioids. Treating such patients requires an individualized approach, informed consent, and a shared decision-making model. Tools exist to help stratify patients for risk of OUD. While improved clinician education in pain control is needed, patients too need to be better informed about the risks and benefits of opioids. Patients may fear pain more than OUD, but opioids are not always the most effective pain reliever for a given patient and some patients do not tolerate or want to take opioids. The association of OUD with mental health disorders (dual diagnosis) can also complicate delivery of care as patients with mental health issues may be less adherent to treatment and may use opioids for “chemical coping” as much as for pain control.

Clinicians' perceptions of barriers to cervical cancer screening for women living with behavioral health conditions: a focus group study

Background

Women with behavioral health (BH) conditions (e.g., mental illness and substance abuse) receive fewer cervical cancer (CC) screenings, are diagnosed at more advanced cancer stages, and are less likely to receive specialized treatments. The aim of this study was to identify barriers that healthcare providers face in providing CC screening to women with BH conditions.

Methods

Guided by the Consolidated Framework for Implementation Research, we conducted four focus groups in North Florida with 26 primary care and BH clinicians and staff to examine perceived barriers to CC screening among their patients with BH conditions to guide the future development of a tailored cervical cancer screening and follow-up intervention. Thematic analysis was used to analyze verbatim transcripts from audiotaped focus groups.

Results

Three main themes of barriers emerged from the data: 1) BH conditions related barriers included a history of trauma, stigma and discrimination, and uncontrolled comorbid conditions, 2) System level barriers related to lack of integration between BH and primary care, and 3) Similar barriers to the general population including lack of health insurance, insufficient processes to send out reminders, and challenges with communicating with patients.

Conclusions

Tailored CC screening interventions that address the unique needs of women with BH conditions are needed. Strategies that address improving trust between patients and healthcare providers, identifying avenues to improve receipt of screening during time-limited clinical visits, connecting BH and primary care providers, and addressing the social determinants of health have potential to improve CC screening rates for women with BH conditions.

Equity-Oriented Healthcare: What It Is and Why We Need It in Oncology

Alarming differences exist in cancer outcomes for people most impacted by persistent and widening health and social inequities. People who are socially disadvantaged often have higher cancer-related mortality and are diagnosed with advanced cancers more often than other people. Such outcomes are linked to the compounding effects of stigma, discrimination, and other barriers, which create persistent inequities in access to care at all points in the cancer trajectory, preventing timely diagnosis and treatment, and further widening the health equity gap. In this commentary, we discuss how growing evidence suggests that people who are considered marginalized are not well-served by the cancer care sector and how the design and structure of services can often impose profound barriers to populations considered socially disadvantaged. We highlight equity-oriented healthcare as one strategy that can begin to address inequities in health outcomes and access to care by taking action to transform organizational cultures and approaches to the design and delivery of cancer services.

Palliative and high-intensity end-of-life care in schizophrenia patients with lung cancer: results from a French national population-based study

Schizophrenia is marked by inequities in cancer treatment and associated with high smoking rates. Lung cancer patients with schizophrenia may thus be at risk of receiving poorer end-of-life care compared to those without mental disorder. The objective was to compare end-of-life care delivered to patients with schizophrenia and lung cancer with patients without severe mental disorder. This population-based cohort study included all patients aged 15 and older who died from their terminal lung cancer in hospital in France (2014-2016). Schizophrenia patients and controls without severe mental disorder were selected and indicators of palliative care and high-intensity end-of-life care were compared. Multivariable generalized log-linear models were performed, adjusted for sex, age, year of death, social deprivation, time between cancer diagnosis and death, metastases, comorbidity, smoking addiction and hospital category. The analysis included 633 schizophrenia patients and 66,469 controls. The schizophrenia patients died 6 years earlier, had almost twice more frequently smoking addiction (38.1%), had more frequently chronic pulmonary disease (32.5%) and a shorter duration from cancer diagnosis to death. In multivariate analysis, they were found to have more and earlier palliative care (adjusted Odds Ratio 1.27 [1.03;1.56]; p = 0.04), and less high-intensity end-of-life care (e.g., chemotherapy 0.53 [0.41;0.70]; p < 0.0001; surgery 0.73 [0.59;0.90]; p < 0.01) than controls. Although the use and/or continuation of high-intensity end-of-life care is less important in schizophrenia patients with lung cancer, some findings suggest a loss of chance. Future studies should explore the expectations of patients with schizophrenia and lung cancer to define the optimal end-of-life care.

Identification of Tobacco-Related Cancer Diagnoses among Individuals with Psychiatric Disorders: A Population-Based Matched Cohort Study Using a Competing Risks Approach from British Columbia

BACKGROUND

Individuals with psychiatric disorders (PD) have a high prevalence of tobacco use. Therefore, we assessed the hazard of receiving a tobacco-related (TR) cancer diagnosis among individuals with PD.

METHODS

Several population-based provincial databases were used to identify individuals in BC diagnosed with depression, schizophrenia, bipolar disorder, anxiety disorders, or multiple PD between 1990 and 2013. A primary population proxy comparison group (appendicitis) was also identified and matched to the psychiatric cohort based on age at cohort entry, gender, year of cohort entry, and postal code. We linked individuals in the cohort and comparison groups with the BC Cancer Registry. Using a competing risks approach, we estimated the effect of having a PD on the risk of receiving a TR cancer diagnosis, in light of the competing risk of mortality.

RESULTS

In total, 165,289 patients were included. Individuals with depression (HR = 0.81; p < 0.01; 95% CI: 0.73-0.91), anxiety disorders (HR = 0.84; p = 0.02; 95% CI: 0.73-0.97), or multiple PD (HR = 0.74; p < 0.01; 95% CI: 0.66-0.83) had a statistically significant lower risk of a TR cancer diagnosis compared to the comparison group. Individuals with schizophrenia (HR = 0.86; p = 0.40; 95% CI: 0.62-1.21) or bipolar disorder (HR = 0.58; p = 0.12; 95% CI: 0.29-1.14), however, showed no evidence of a statistically significant difference from the comparison group.

INTERPRETATION

We found that individuals with depression, anxiety disorders, or multiple PD diagnoses had a significantly reduced risk of receiving a tobacco-related cancer diagnosis. These results were unexpected and could be explained by individuals with a PD having barriers to a cancer diagnosis rather than a true decreased incidence.

Associations between comorbidities and advanced stage diagnosis of lung, breast, colorectal, and prostate cancer: A systematic review and meta-analysis

Comorbidities and advanced stage diagnosis (ASD) are both associated with poorer cancer outcomes, but the association between comorbidities and ASD is poorly understood. We summarized epidemiological evidence on the association between comorbidities and ASD of selected cancers in a systematic review and meta-analysis. We searched PubMed and Web of Science databases up to June 3rd, 2021 for studies assessing the association between comorbidities and ASD of lung, breast, colorectal, or prostate cancer. Summary odds ratios (ORs) and 95% confidence intervals (95%CIs) were calculated using random-effects models. Also, potential variations in the associations between comorbidities and ASD by cancer type were investigated using random-effects meta-regression. Thirty-seven studies were included in this review, including 8,069,397 lung, breast, colorectal, and prostate cancer patients overall. The Charlson comorbidity index score was positively associated with ASD (stages III-IV) of breast cancer but was inversely associated with ASD of lung cancer (p_interaction = 0.004). Regarding specific comorbidities, diabetes was positively associated with ASD (OR = 1.17, 95%CI = 1.09-1.26), whereas myocardial infarction was inversely associated with ASD (OR = 0.84, 95%CI = 0.75-0.95). The association between renal disease and ASD differed by cancer type (p_interaction < 0.001). A positive association was found with prostate cancer (OR = 2.02, 95%CI = 1.58-2.59) and an inverse association with colorectal cancer (OR = 0.84, 95%CI = 0.70-1.00). In summary, certain comorbidities (e.g., diabetes) may be positively associated with ASD of several cancer types. It needs to be clarified whether closer monitoring for early cancer signs or screening in these patients is reasonable, considering the problem of over-diagnosis particularly relevant in patients with short remaining life expectancy such as those with comorbidities. Also, evaluation of the cost-benefit relationship of cancer screening according to the type and severity of comorbidity (rather than summary scores) may be beneficial for personalized cancer screening in populations with chronic diseases.

Encouraging participation in colorectal cancer screening for people with schizophrenia: A randomized controlled trial

OBJECTIVE

We examined the efficacy of a case management approach to improve participation in colorectal cancer screening among people with schizophrenia.

METHODS

This was a randomized, parallel group trial. We recruited outpatients with schizophrenia aged 40 years or over from two psychiatric hospitals in Japan. Participants were randomly assigned (1:1) to treatment as usual or case management intervention plus treatment as usual using a web-based system. Attending clinicians and participants were unmasked to the allocation. Case management included education and patient navigation for colorectal cancer screening using a fecal occult blood test. Treatment as usual included direct mail government recommendations. The primary endpoint was participation in colorectal cancer screening assessed using municipal records. We also assessed the secondary endpoint of participation in other cancer screenings (lung, gastric, breast, and cervical).

RESULTS

Between 3 June and 9 September 2019, 172 eligible participants were randomly assigned to the case management plus treatment as usual group (n = 86) or treatment as usual group (n = 86). One participant was ineligible and another withdrew consent; both were excluded from analysis. A significantly higher proportion of participants received colorectal cancer screening in the case management plus treatment as usual group than in the treatment as usual group (40 [47.1%] of 85 participants vs. 10 [11.8%] of 85 participants, p < 0.0001). The proportion of lung cancer screening also increased. No serious adverse events associated with the study intervention occurred.

CONCLUSION

The case management intervention to encourage participation in colorectal cancer screening was effective for patients with schizophrenia.

Improving Surgical Quality for Patients with Mental Health Illnesses: A Narrative Review

OBJECTIVE

To establish and define disparities in care for patients presenting with surgical disease who have pre-existing mental health diagnoses.

SUMMARY BACKGROUND DATA

Mental illness affects approximately 6.7 million Canadians. For them, stigma, comorbid disorders, and sequelae of psychiatric diagnoses can be barriers patients face to receive equitable healthcare. The goal of this review is to define inequities in surgical care for patients with pre-existing mental illness.

METHODS

We search OVID Medline, Pubmed, EMBASE, and the Cochrane review files using a combination of search terms using a PICO (population, intervention, comparison, outcome) model focusing on surgical care for patients with mental illness.

RESULTS

The literature on mental illness in surgical patients focused primarily on preoperative and postoperative disparities in surgical care between patients with and without a diagnosis of mental illness. Preoperatively, patients were 7.5-40% less likely to be deemed surgical candidates, were less likely to receive testing, and were more likely to present at later stages of their disease or have delayed surgical care. Similar themes arose in the postoperative period: patients with mental illness were more likely to require ICU admission, were up to 3 times more likely to have a prolonged length of hospital stay, had a 14-270% increased likelihood of having postoperative complications, and had significantly higher healthcare costs.

CONCLUSIONS

Surgical patients with preexisting psychiatric diagnoses have a propensity for worse perioperative outcomes compared to patients without reported mental illness. Taking a thorough psychiatric history can potentially help surgical teams address disparities and access to care as well as anticipate and prevent adverse outcomes.

Mental disorders, length of hospitalization, and psychopharmacy-New approaches to identify barriers to psychological support for patients with cancer

BACKGROUND

Despite abundant evidence that emotional distress is frequent in cancer patients and associated with adverse health outcomes, distress screening rates and adequate referrals to psychological support programs among those in need are insufficient in many cancer centers. We therefore aimed to analyze patient- and treatment-related barriers to distress screening and referrals to psychological support as a mandatory component of best-practice cancer care.

METHOD

In the present explorative study, latent class analysis was used to identify homogeneous subgroups among 4837 patients diagnosed with cancer between 2011 and 2019.

RESULTS

Four subgroups were identified. Patients with a mental disorder and psychopharmacology were least probable to be screened for distress. Together with patients aged 65 or older and male patients, they were also less likely to receive psychological support. Patients hospitalized for 28 days or longer were most likely to be both screened and to receive psychological support.

CONCLUSIONS

Clinicians and researchers are recommended not neglect patients with mental disorders and psychopharmacological treatment as well as male and elderly patients when screening for distress and providing access to psychological support.

Association of pre-existing mental illness with all-cause and cancer-specific mortality among Medicare beneficiaries with pancreatic cancer

BACKGROUND

Among patients with pancreatic cancer, the association of pre-existing mental illness with long-term outcomes remains unknown.

METHODS

Individuals diagnosed with pancreatic adenocarcinoma were identified in the SEER-Medicare database. Patients were classified as having mental illness if an ICD9/10CM code for anxiety, depression, bipolar disorder, schizophrenia or other psychotic disorder was recorded.

RESULTS

Among the 54,234 Medicare beneficiaries with pancreatic cancer, roughly 1 in 12 (n = 4793, 8.83%) individuals had a diagnosis of a mental illness. The majority (n = 4029, 84.1%) had anxiety or depression, while 16% (n = 764) had bipolar/schizophrenic disorders. On multivariable analysis, among patients with early stage cancer, individuals with pre-existing anxiety/depression and bipolar/schizophrenic disorders had 22% (OR 0.78, 95% CI 0.69-0.86) and 46% (OR 0.54, 95% CI 0.42-0.70) reduced odds, respectively, to undergo cancer-directed surgery. Furthermore, patients with a pre-existing history of bipolar/schizophrenic disorders had a 20% (HR 1.20, 95% CI 1.21-1.40) higher risk of all-cause mortality and 27% (HR 1.27, 95% CI 1.17-1.37) higher risk of pancreatic cancer-specific mortality compared to individuals without a history of mental illness.

CONCLUSION

One in twelve patients with pancreatic cancer had a pre-existing mental illness. Individuals with mental illness were more likely to have worse overall and cancer-specific long-term outcomes.

Using additive and relative hazards to quantify colorectal survival inequalities for patients with a severe psychiatric illness

PURPOSE

We examine colorectal cancer (CRC) survival for patients with and without severe psychiatric illness (SPI) to demonstrate the use of relative and absolute effects.

METHODS

This included a retrospective cohort study of patients with CRC diagnosed between 01/04/2007 and 31/12/2012. SPI was defined as major depression, bipolar disorder, schizophrenia, and other psychotic illnesses occurring six months to five years preceding cancer diagnosis and categorized as inpatient, outpatient, or none. Associations between SPI history and death were examined using Cox proportional hazards regression (hazard ratios (HRs)) and Aalen's semiparametric additive hazards regression (absolute differences).

RESULTS

A total of 24,507 patients with CRC were included. A total of 58.1% of patients with inpatient SPI history died, and 47.1% of patients with outpatient SPI history died. Patients with an outpatient SPI history had a 40% (HR 1.40, 95% confidence interval: 1.22-1.59) increased hazard of death, and patients with an inpatient SPI history had a 91% increased hazard of death (HR 1.91, 95% confidence interval: 1.63-2.25), relative to no history of a mental illness. Outpatient SPI history was associated with additional 33 deaths per 1000 person years, and inpatient SPI was associated with additional 82 deaths per 1000 person years.

CONCLUSIONS

We encourage future studies examining inequities with time-to-event data to use this method addressing both relative and absolute effect.

The effect of a severe psychiatric illness on colorectal cancer treatment and survival: A population-based retrospective cohort study

OBJECTIVES

To identify inequalities in cancer survival rates for patients with a history of severe psychiatric illness (SPI) compared to those with no history of mental illness and explore differences in the provision of recommended cancer treatment as a potential explanation.

DESIGN

Population-based retrospective cohort study using linked cancer registry and administrative data at ICES.

SETTING

The universal healthcare system in Ontario, Canada.

PARTICIPANTS

Colorectal cancer (CRC) patients diagnosed between April 1st, 2007 and December 31st, 2012. SPI history (schizophrenia, schizoaffective disorders, other psychotic disorders, bipolar disorders or major depressive disorders) was determined using hospitalization, emergency department, and psychiatrist visit data and categorized as 'no history of mental illness, 'outpatient SPI history', and 'inpatient SPI history'.

MAIN OUTCOME MEASURES

Cancer-specific survival, non-receipt of surgical resection, and non-receipt of adjuvant chemotherapy or radiation.

RESULTS

24,507 CRC patients were included; 482 (2.0%) had an outpatient SPI history and 258 (1.0%) had an inpatient SPI history. Individuals with an SPI history had significantly lower survival rates and were significantly less likely to receive guideline recommended treatment than CRC patients with no history of mental illness. The adjusted HR for cancer-specific death was 1.69 times higher for individuals with an inpatient SPI (95% CI 1.36-2.09) and 1.24 times higher for individuals with an outpatient SPI history (95% CI 1.04-1.48). Stage II and III CRC patients with an inpatient SPI history were 2.15 times less likely (95% CI 1.07-4.33) to receive potentially curative surgical resection and 2.07 times less likely (95% CI 1.72-2.50) to receive adjuvant radiation or chemotherapy. These findings were consistent across multiple sensitivity analyses.

CONCLUSIONS

Individuals with an SPI history experience inequalities in colorectal cancer care and survival within a universal healthcare system. Increasing advocacy and the availability of resources to support individuals with an SPI within the cancer system are warranted to reduce the potential for unnecessary harm.

The overall and sex- and age-group specific incidence rates of cancer in people with schizophrenia: a population-based cohort study

AIMS

Decades of research show that people with schizophrenia have an increased risk of death from cancer; however, the relationship between schizophrenia and cancer incidence remains less clear. This population-based study investigates the incidence of seven common types of cancer among people with a hospital diagnosis of schizophrenia and accounting for the effects of age, sex and calendar time.

METHODS

This population-based study used 1990-2013 data from three nationwide Swedish registries to calculate the incidence (in total, by age group and by sex) of any cancer and of lung, oesophageal, pancreatic, stomach, colon, (in men) prostate and (in women) breast cancer in 111 306 people with a hospital diagnosis of schizophrenia. The incidence in people with diagnosed schizophrenia was compared with the incidence in the general population. Risk estimates accounted for the effects of calendar time.

RESULTS

In 1 424 829 person-years of follow-up, schizophrenia did not confer an overall higher cancer risk (IRR 1.02, 95% CI 0.91-1.13) but was associated with a higher risk for female breast (IRR 1.19, 95% CI 1.12-1.26), lung (IRR 1.42, 95% CI 1.28-1.58), oesophageal (IRR 1.25, 95% CI 1.07-1.46) and pancreatic (IRR 1.10, 95% CI 1.01-1.21) and a lower risk of prostate (IRR 0.66, 95% CI 0.55-0.79) cancer. Some age- and sex-specific differences in risk were observed.

CONCLUSIONS

People with schizophrenia do not have a higher overall incidence of cancer than people in the general population. However, there are significant differences in the risk of specific cancer types overall and by sex calling for efforts to develop disease-specific prevention programmes. In people with schizophrenia, higher risk generally occurs in those <75 years.

Cancer staging in individuals with a severe psychiatric illness: a cross-sectional study using population-based cancer registry data

BACKGROUND

Advanced cancer stage at diagnosis may explain high cancer mortality among patients with a severe psychiatric illness (SPI). Studies to date investigating advanced stage cancer at diagnosis as a potential explanation for high cancer mortality in individuals with a history of mental illness have been inconclusive. We examined the relationship between a SPI history and unknown cancer stage at diagnosis in colorectal cancer (CRC) patients.

METHODS

This was a population-based, cross-sectional study using linked administrative databases of CRC patients diagnosed between 01/04/2007 and 31/12/2012. Individuals who had a history of mental illness but did not meet the definition of a SPI were excluded. An SPI was measured in the 5 years prior to the cancer diagnosis and categorized as inpatient, outpatient or no SPI. Individuals with a best stage in Stage 0 to Stage IV were considered staged and absence of staging information was defined as unknown stage. The risk of unknown stage cancer was estimated using modified Poisson regression.

RESULTS

The final study cohort included 24,507 CRC patients. 258 (1.1%) individuals experienced a history of inpatient SPI and 482 (2.0%) experienced outpatient SPI. After adjusting for confounders, CRC patients with an inpatient or outpatient history of SPI were at greater risk of having missing TNM stage at diagnosis, compared to patients with no history of a mental illness (RR 1.45 (95% CI: 1.14-1.85) and RR1.17 (95% CI 0.95-1.43), respectively). The results did not change when alternate practices to assign SPI history using administrative data were used.

CONCLUSIONS

Individuals with an SPI, especially those with a psychiatric admission, were more likely to have missing stage data compared to individuals without a history of a mental illness. Incomplete and low quality cancer staging data likely undermines the quality of cancer care following initial diagnosis. Understanding why patients with an SPI are missing this information is a critical first step to providing excellent care to this vulnerable population.
