Increased suicide risk in cancer patients in Tyrol/Austria

Suicide Mortality Risk among Patients with Lung Cancer-A Systematic Review and Meta-Analysis

The risk for suicide in patients with cancer is higher compared to the general population. However, little is known about patients with lung cancer specifically. We therefore implemented a systematic review and random-effects meta-analysis of retrospective cohort studies on suicide in patients with lung cancer. We searched a high number of common databases up to 02/2021. For the systematic review, a total of 23 studies was included. To exclude bias due to patient sample overlap, the meta-analysis was performed on 12 studies. The pooled standardized mortality ratio (SMR) for suicide was 2.95 (95% Confidence Interval (CI) = 2.42-3.60) for patients with lung cancer as compared to the general population. Subgroups with a pronouncedly higher risk for suicide compared to the general population were found for patients living in the USA (SMR = 4.17, 95% CI = 3.88-4.48), with tumors of late stage (SMR = 4.68, 95% CI = 1.28-17.14), and within one year after diagnosis (SMR = 5.00, 95% CI = 4.11-6.08). An increased risk for suicide was found in patients with lung cancer, with subgroups at particular risk. Patients at increased risk should be monitored more closely for suicidality and should receive specialized psycho-oncological and psychiatric care. Further studies should clarify the role of smoking and depressive symptoms on suicidality among lung cancer patients.

Scrutinizing the Profile and Risk Factors of Suicide: A Perspective from a Case-Control Study Focused on a Northern Region of Spain

Suicide is a major public health problem the prevention of which has become a priority, and, to this end, knowledge of its risk factors is essential. This study aims to evaluate the impact of some social, medico-legal, and clinical issues on suicide deaths. A total of 135 cases were identified as suicides that occurred in a region of northern Spain between 2018 and 2020. Controls (three for each case) were matched by age, sex, and urban-rural areas. The information was collected retrospectively through electronic health record systems. A binary logistic regression analysis was performed to study the association between individual risk factors and suicide. Being male (78.5%), between 40 and 60 years of age, unmarried (70.9%), and unemployed (85%) were associated with suicide deaths. Although the existence of a previous self-harm attempt is presented as the most robust risk factor (OR 22.121 [8.997-54.389]), the presence of a psychiatric diagnosis (OR 12.583 [7.686-20.601]) and cancer (OR 3.729 [1.845-7.536]) also showed a significant relationship with suicide (p < 0.05). Defining and knowing the risk factors for suicide helps to better understand the profiles of those individuals who are vulnerable, and enables prevention actions to be taken in both social and medical spheres.

Systematic review on factors associated with self-perceived burden among cancer patients

INTRODUCTION

Cancer is the leading cause of death in the world. There was a high prevalence of high self-perceived burden (SPB) among cancer patients and this could bring adverse consequences to the physical and mental health of cancer patients, which can lead to suicide if not treated well. This review aims to determine the prevalence of SPB among cancer patients and its risk factors.

METHODS

Published journals before September 2021, from five databases (PubMed, ScienceDirect, Springer, Cochrane, and CNKI) were retrieved according to the keywords. The keywords used included cancer patients, terminally ill patients, cancer, SPB, self-perceived burden, self-burden, self-perceived, factor, predictor, associated factor, determinants, risk factor, prognostic factor, covariate, independent variable, and variable. The quality of the inclusion and exclusion criteria was independently reviewed by three researchers.

RESULTS

Out of 12,712 articles, there are 22 studies met the eligibility criteria. The prevalence of SPB among cancer patients ranged from 73.2 to 100% in Malaysia, China, and Canada. Most of them had moderate SPB. Out of the reported factors, age, gender, marital status, ethnicity, residence, educational level, occupational status, family income, primary caregiver, payment methods, disease-related factors, psychological factors, and physical factors were mostly reported across the studies.

CONCLUSIONS

In conclusion, SPB prevalence is high in cancer patients. Therefore, hospitals, non-governmental organizations, relevant policymakers, and communities can provide special programs for high-risk groups to provide psychological guidance or design corresponding interventions to reduce the SPB level of patients and improve the quality of life.

Factors Affecting Suicidal Thoughts in Breast Cancer Patients

Background and Objectives: Women diagnosed with breast cancer experience severe trauma. Psychological help for breast cancer patients is not sufficient because of limited professional resources. The goal of this study was to identify groups of breast cancer patients with the greatest suicidal risk, who could be the first target for psychosocial interventions. Materials and Methods: The study included 421 women with stage T1–T3/N0–N3/M0 breast cancer. We provided women with a set of questionnaires 1–2 days prior to breast surgery and one year after surgery. One hundred eighty-eight patients completed the questionnaires after one year. We used the Beck Depression Inventory Second Edition (BDI-II) item Suicidal Thoughts or Intentions for the assessment of suicidal risk. The Impact of Event Scale-Revised (IES-R) was used to measure the risk of PTSD and the Vrana–Lauterbach Traumatic Events Questionnaire-Civilian, TEQ-C (TEQ-CV) was used to measure whether patients had experienced other traumatic events in their lifetime. Results: The incidence of suicidal ideation one year after surgery increased from 4.3% to 12.8% of patients. Patients who lived in rural areas had a two times greater risk of suicidal thoughts than patients who lived in urban areas. Working patients were 2.5 times more likely to have suicidal thoughts prior to surgery. Severely traumatic events increased the chances of suicidal ideation (OR 7.72; 95% CI 1.63–36.6; p = 0.01). The symptoms of PTSD showed a threefold increase in the likelihood of suicidal ideation (OR 2.89; 95% CI 0.98–8.55; p = 0.05). Conclusions: Living in the countryside, having a history of traumatic experience, having a paid job and having symptoms of post-traumatic stress disorder influence suicidal ideation in breast cancer patients. Particular attention should be drawn to individuals with multiple risk factors.

Incidence and risk factors of suicide in patients with lung cancer: a scoping review

PURPOSE

To explore the high-risk period of the occupation of suicide after diagnosis; and clarify the risk factors of suicidal behaviors (suicidal ideation, suicide attempt, and suicidal death) behind the lung cancer patients during the cancer cure process.

METHODS

This scoping review was conducted through the whole month of April 2021. We extracted data of the suicide mortality after diagnosis and latent risk factors of suicidal behaviors among lung cancer patients where we used to study from the two online databases which are PubMed and Web of Science. Two online databases were searched and written in English without age restriction. To note that the standardized mortality ratio (SMR), person-years, and odds ratio (OR) associated with lung cancer were documented.

RESULTS

Out of 570 records, 23 studies mentioned suicidal behaviors and lung cancer met the included criteria. Eleven (n = 47.8%) of the selected publications reported changes in suicide mortality. None of them reported suicidal ideation or suicide attempt after diagnosis. The individuals with lung cancer have significantly higher rates of suicidal death (SMR, 2.04-13.4) during the first years after diagnosis and decrease over subsequent years (SMR, 0.66-3.17). The median time from cancer diagnosis to suicide death was around 7 months. Across all studies with the 22 studies that examined factors, we extracted the data of the suicidal ideation (n = 3), suicide attempt (n = 1), and suicidal death (n = 18) in individuals. For patients with suicidal ideation, there was a significantly higher incidence in males than in females. Among patients who attempted suicide, the incidence of mental illness is greater than the incidence of physical illness. Factors for suicidal death, including gender (male, 56.3-100%), prognosis tumors (poor, 25.8-66.3%), marital status (widowhood or unmarried, 19-75.7%), and age of patients (> 70 years, 24.5-47%) with lung cancer, play a vital role. Treatment of lung cancer is expected to affect a patient in his/her mental state.

CONCLUSION

Overall, our finding indicates that lung cancer patients have been presented with a higher incidence of suicide death in a specific period, especially the early years after diagnosis. Discovering risk factors for suicide helps prevent potential suicide. It is essential to screen lung cancer patients for suicidal ideation, especially those with high-risk factors. Future prospective studies are necessary to confirm these findings to support care.

Risk factors for suicide in individuals with cancer: an integrative literature review

OBJECTIVE

to develop an integrative literature review on risk factors for suicide in individuals with cancer.

METHOD

searching for articles was conducted in the Scientific Electronic Library Online, Medicinal Literature Analysis and Retrieval System Online, Latin American & Caribbean Literature in Health Sciences, Cumulative Index to Nursing and Allied Health Literature and SciVerse Scopus databases, using the descriptors "suicide" and "cancer".

RESULTS

eighteen articles were selected. Lung, bladder and colorectal cancers are the types of highest risk for suicide. Male, white and over 60 years of age are demographic factors with higher risk for suicide in individuals with cancer.

CONCLUSION

this review made it possible to verify that cancer may be a risk factor for suicide. This evidence can be useful for planning preventive actions in order to reduce the risk of suicide.

Incidence of suicide death in patients with cancer: A systematic review and meta-analysis

BACKGROUND

Growing evidence indicated the higher risk of suicide in cancer survivors compared with general population. Our aim is to systematically quantify the extent of suicide death and identify risk factors associated with the incidence of suicide in cancer patients.

METHODS

We conducted a meta-analysis of relevant studies published in English or Chinese before May 20, 2020. Suicide rate and the number of suicide death were extracted. Our main outcome was suicide rate per 100,000 person-years with 95% CIs using random-effects model.

RESULTS

The pooled incidence of suicide death was 39.72 per 100,000 person-years (95%CI, 33.91-46.52, I ²= 99.6%, P <0 .001). The suicide rate for cancer patients was higher in men (57.78, 95%CI, 47.31-70.56) than in women (14.47, 95%CI, 11.27-18.57). For both sexes combined, esophagus cancer had the highest rate of suicide (87.71, 95%CI, 27.42-280.54). By sex, suicide rates ranked first in males and females were pancreas cancer (195.70, 95%CI, 129.55-295.61) and esophagus cancer (18.34, 95%CI, 5.92-56.84), respectively. The highest suicide rate was 61.02(95%CI, 53.66-69.40) in Asia, and Oceania (24.07, 95%CI, 20.78-27.88) had lowest suicide rate. Suicide rate had a downward trend by years after diagnosis, with the first six months after cancer diagnosis clearly standing out (89.33, 95%CI, 50.64-157.58).

LIMITATIONS

Included studies came from high-income countries and our results might not represent the suicide rate among cancer patients in low- and middle-income countries.

CONCLUSIONS

The incidence of suicide among cancer patients was high despite the declined trend recent years, which emphasized psychological health aspects of interventions and perfecting suicide prevention programs.

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.

Interventions for Reducing Suicide Risk in Cancer Patients: A Literature Review

The suicide risk of people diagnosed with cancer is two times higher than the general population. The number of cases of diagnosed cancer is estimated to rise by 70% over the next two decades. Evidence-based prevention strategies are necessary to protect this vulnerable group of individuals. The purpose of this review was to find out the risk factors of suicide and which types of interventions can serve as prevention strategies. Psychosocial interventions, pharmacotherapy and physical activity can play a preventive role in reducing psychosocial and physical risk factors, such as mental disorders, poor social support, poor performance status and pain. Further research is needed to develop effective suicide prevention strategies for cancer patients.

Suicide, other externally caused injuries and cardiovascular death following a cancer diagnosis: study protocol for a nationwide population-based study in Japan (J-SUPPORT 1902)

INTRODUCTION

A growing body of literature has demonstrated that cancer patients have a higher risk of suicide and cardiovascular mortality compared with the general population, especially immediately after a cancer diagnosis. Using data from the National Cancer Registry in Japan launched in January 2016, we will conduct the first nationwide population-based study in Japan to compare incidence of death by suicide, other externally caused injuries (ECIs) and cardiovascular disease following a cancer diagnosis with that of the general population in Japan. We will also aim to identify the patient subgroups and time periods associated with particularly high risk.

METHODS AND ANALYSIS

Our study subjects will consist of cancer cases diagnosed between 1 January 2016 and 31 December 2016 in Japan and they will be observed until 31 December 2018. We will calculate standardised mortality ratios (SMRs) and excess absolute risks (EARs) for suicide, other ECIs and cardiovascular death compared with the general population in Japan, after adjustment for sex, age and prefecture. SMRs and EARs will be calculated separately in relation to a number of factors: sex; age at diagnosis; time since cancer diagnosis; prefecture of residence at diagnosis; primary tumour site; behaviour code of tumour; extension of tumour; whether definitive surgery of the primary site was performed; and presence/absence of multiple primary tumours.

ETHICS AND DISSEMINATION

The study protocol was approved by the institutional review board and ethics committee of the National Cancer Center Japan and Nagoya City University Graduate School of Medical Sciences. The findings will be disseminated through peer-reviewed publications and conference presentations.

Lung cancer patients have the highest malignancy-associated suicide rate in USA: a population-based analysis

PURPOSE

Previous studies have reported that psychological and social distresses associated with a cancer diagnosis have led to an increase in suicides compared to the general population. We sought to explore lung cancer-associated suicide rates in a large national database compared to the general population, and to the three most prevalent non-skin cancers [breast, prostate and colorectal cancer (CRC)].

METHODS

The Surveillance, Epidemiology and End Results (SEER) database (1973-2013) was retrospectively reviewed to identify cancer-associated suicide deaths in all cancers combined, as well as for each of lung, prostate, breast or CRCs. Suicide incidence and standardised mortality ratio (SMR) were estimated using SEER*Stat-8.3.2 program. Suicidal trends over time and timing from cancer diagnosis to suicide were estimated for each cancer type.

RESULTS

Among 3,640,229 cancer patients, 6,661 committed suicide. The cancer-associated suicide rate was 27.5/100,000 person years (SMR = 1.57). The highest suicide risk was observed in patients with lung cancer (SMR = 4.17) followed by CRC (SMR = 1.41), breast cancer (SMR = 1.40) and prostate cancer (SMR = 1.18).Median time to suicide was 7 months in lung cancer, 56 months in prostate cancer, 52 months in breast cancer and 37 months in CRC (p < 0.001).We noticed a decreasing trend in suicide SMR over time, which is most notable for lung cancer compared to the other three cancers. In lung cancer, suicide SMR was higher in elderly patients (70-75 years; SMR = 12), males (SMR = 8.8), Asians (SMR = 13.7), widowed patients (SMR = 11.6), undifferentiated tumours (SMR = 8.6), small-cell lung cancer (SMR = 11.2) or metastatic disease (SMR = 13.9) and in patients who refused surgery (SMR = 13).

CONCLUSION

The cancer-associated suicide rate is nearly twice that of the general population of the United States of America. The suicide risk is highest among the patients with lung cancer, particularly elderly, widowed, male patients and patients with unfavourable tumour characteristics. The identification of high-risk patients is of extreme importance to provide proper psychological assessment, support and counselling to reduce these rates.

Increasing suicide risk among cancer patients in Lithuania from 1993 to 2012: a cancer registry-based study

Certain groups of individuals seem to have an increased risk of committing suicide, and a number of studies have reported an increased risk of suicide among cancer patients. In this study, we aim to estimate the risk of suicide among cancer patients in Lithuania over the period 1993-2012. The records of patients diagnosed with primary cancer were extracted from the population-based Lithuanian Cancer Registry and 273 511 cases of first cancer were included in the analysis. Sex, age and calendar period-standardized mortality ratios (SMRs) were calculated by dividing the observed numbers of suicides among cancer patients by the expected number using national rates. An increased suicide risk was found for both sexes combined [SMR=1.31, 95% confidence interval (CI): 1.21-1.41] compared with the general population. For all cancer sites except melanoma and skin, and breast and thyroid cancers, the relative suicide risk was elevated. The suicide risk was almost three-fold higher for advanced-stage patients compared with the general population (SMR=2.89, 95% CI: 2.24-3.73). The highest suicide risk observed in our study was during the first 3 months following cancer diagnosis (SMR=2.43, 95% CI: 1.96-3.01), indicating a critical period shortly after diagnosis. Despite ongoing increases in survival among cancer patients and decreases in suicide mortality in the general Lithuanian population during our study period, the increasing risk for suicide indicates that cancer patients' clinical and psychosocial needs remain unsatisfied. The major clinical implication of these data suggests the importance of multidisciplinary preventive interventions.

Cancer patients' wish for psychological support during outpatient radiation therapy : Findings from a psychooncological monitoring program in clinical routine

BACKGROUND

Cancer patients frequently suffer from physical and psychosocial impairments due to their disease and its treatment. Psychooncology (PO) can help to cope with stress resulting from outpatient radiotherapy (RT) treatment. There are currently few data regarding patients' wishes for PO support. The aim of this study was to investigate the number of patients with a wish for PO, treatment paths, and predictors of the wish for PO among cancer patients at the beginning of RT.

METHODS

The results of routine psychological stress screening (Hornheide screening instrument; cut-off  ≥ 4) of 944 cancer patients between 2015 and 2017 were analyzed in a retrospective cross-sectional study. Predictors for a wish for PO support were identified by stepwise binary logistic regression, in which sociodemographic and treatment data were included in addition to the screening items.

RESULTS

Around 20% of patients had above-average stress levels and 13% expressed a wish for PO support (participation rate was approximately 55%). Low emotional wellbeing (OR = 11.3) and lack of social support (OR = 9.4) were strong predictors for this treatment wish. Among patients with pancreatic cancer, head and neck tumors, and hematologic disease, there was a substantial difference between the degree of psychological stress and the wish for treatment. Patients with urological (23.5%) and lung tumors (20.9%) most frequently expressed a wish for PO support.

CONCLUSION

Patient-reported psychosocial problems were better predictors of a wish for PO support than sociodemographic or clinical data. Stress screening should thus be implemented in clinical routine.

Risk of suicide within 1 year of cancer diagnosis

The association of the risk of suicide with cancer at different time points after a new cancer diagnosis is unclear. This study explored the suicide hazard at different time points after a first cancer diagnosis during the 1-year period before suicide. This case-crossover study included 2,907 suicide cases from 2002 to 2012 in Taiwan and compared the odds of suicide risk at different time points during one year after any cancer diagnosis with self-matched periods. The 13th month preceding the suicide date was used as the control period, and the hazard period was the duration from the 1st to 12th month in the conditional logistic regression for case-crossover comparisons. Among major groups of cancers, group of lip, oral cavity and pharynx cancers tended to have higher risk of suicide than other groups of cancers. The first month of cancer diagnosis was associated with the highest risk of suicide compared with the 13th month before suicide. The odds ratio (OR) of suicide were significantly in the first six months after cancer diagnosis but declined afterwards. For example, the adjusted OR was 3.47 [95% confidence interval (CI) = 2.60-4.62] in the first month and 1.53 (95% CI = 1.11-2.12) in the sixth month following cancer diagnosis. These findings provide clinicians with a vital reference period during which sufficient support and necessary referral to mental health support should be provided to reduce the risk of suicide among patients with newly diagnosed cancer morbidity.

Can a person-centred-care intervention improve health-related quality of life in patients with head and neck cancer? A randomized, controlled study

BACKGROUND

The incidence of head and neck cancer is increasing slightly. Head and neck cancer but also it's necessary and often successful treatment may affect general domains of health-related quality of life and provoke a variety of adverse symptoms and side effects, both during and after treatment. The objective of this study was to compare a person-centred care intervention in terms of health-related quality of life, disease-specific symptoms or problems, with traditional care as a control group for patients with head and neck cancer.

METHODS

In this randomized controlled trial, person-centred-care intervention and traditional care (control) groups comprised 54 and 42 patients, respectively. Outcome measures used were: the EORTC QLQ-C30 and the EORTC QLQ-C35. Both groups answered the questionnaires at baseline and after 4, 10, 18 and 52 weeks from start of treatment. The questionnaires' scores were compared between groups by using independent samples test and non-parametric test for continuous variables. For categorical data, Fisher's exact test was used. Longitudinal data were analysed using generalized linear models for normally distributed repeated measures data.

RESULTS

At baseline, the intervention and control groups were comparable in terms of medical and sociodemographic variables, clinical characteristics, health-related quality of life and disease-specific symptoms or problems. At all the follow-up points, even during the worst period for the patients, the person-centred-care group consistently reported better scores than the control group. The differences were numerically but not always statistically significant. When testing longitudinal data, statistically significant results were found for head and neck cancer-specific problems, swallowing (p = 0.014), social eating (p = 0.048) and feeling ill (p = 0.021).

CONCLUSIONS

The results from this study suggest that adopting the person-centred-care concept practiced here could be a way to improve function and wellbeing in patients with head and neck cancer.

TRIAL REGISTRATION

The study was retrospectively registered in 2016-12-05 in Clinical Trials gov. "Can a Person-centred-care Intervention Improve Health-related Quality of Life in Patients With Head and Neck Cancer" registration number: NCT02982746.

A systematic review of physical illness, functional disability, and suicidal behaviour among older adults

OBJECTIVES

To conduct a systematic review of studies that examined associations between physical illness/functional disability and suicidal behaviour (including ideation, nonfatal and fatal suicidal behaviour) among individuals aged 65 and older.

METHOD

Articles published through November 2014 were identified through electronic searches using the ERIC, Google Scholar, PsycINFO, PubMed, and Scopus databases. Search terms used were suicid* or death wishes or deliberate self-harm. Studies about suicidal behaviour in individuals aged 65 and older with physical illness/functional disabilities were included in the review.

RESULTS

Sixty-five articles (across 61 independent samples) met inclusion criteria. Results from 59 quantitative studies conducted in four continents suggest that suicidal behaviour is associated with functional disability and numerous specific conditions including malignant diseases, neurological disorders, pain, COPD, liver disease, male genital disorders, and arthritis/arthrosis. Six qualitative studies from three continents contextualized these findings, providing insights into the subjective experiences of suicidal individuals. Implications for interventions and future research are discussed.

CONCLUSION

Functional disability, as well as a number of specific physical illnesses, was shown to be associated with suicidal behaviour in older adults. We need to learn more about what at-risk, physically ill patients want, and need, to inform prevention efforts for older adults.
