The risk of suicide in cancer patients: a review of the literature

Depression and cancer

Depression in patients with cancer can present a challenging clinical problem for both general practitioners and the oncology team. Detecting depression in a patient with cancer, who may be debilitated and in pain, can be difficult. Cancer treatments can complicate antidepressant choices. Community-based psychologists are an important resource for helping manage less complex and less severe psychological problems that can arise in the cancer setting. Specialist psycho-oncology services (where available) can help with more complex and severe presentations of depression by advising on the prescription of antidepressants and providing psychotherapy programs that address the patient's psychological orientation and needs and consider the patient's cancer type and stage.

Increased suicide risk in cancer patients in Tyrol/Austria

OBJECTIVES

To investigate whether suicide risk in Tyrol/Austria was increased for cancer patients as compared to the general population and whether subgroups at excess risk could be defined.

STUDY DESIGN AND SETTING

Cohort design based on all malignant cancer cases diagnosed in Tyrol between 1991 and 2010 and excluding nonmelanoma skin cancer. Entry date was date of diagnosis of the index cancer; exit date was either date of suicide or date of death for reasons other than suicide or end of follow-up (Dec 31, 2011). Standardized mortality ratios (SMRs) were computed in the classical way after adjustment for sex, age and year of follow-up.

RESULTS

For all cancer sites except nonmelanoma skin cancer, we observed a SMR of 1.86 [95% confidence interval (CI), 1.57-2.19]. Suicide risk was greatest during the first 6 months after diagnosis with an SMR of 4.74 (95% CI, 3.27-6.66) and was more than fivefold in cases with advanced Stage IV. We observed the greatest excess risk for suicide in patients with head and neck cancers (13 suicides; SMR, 4.73; 95% CI, 2.52-8.09) and lung cancer (14 suicides; SMR, 4.16; 95% CI, 2.27-6.98).

CONCLUSION

In our study population in Tyrol/Austria, we observed a twofold suicide risk in cancer patients as compared with the general population, with the excess risk concentrated in the period shortly after diagnosis and in patients with poor prognosis. Therefore, psychooncological care should be intensified in this group of patients.

Risk factors for suicide among older adults with cancer

OBJECTIVE

To determine whether the increased risk of suicide for individuals with cancer may be explained by functional limitations, lack of social support, or other factors.

METHOD

In this population-based case-control study, interviews of primary informants for suicides in the state of North Carolina were compared to interviews with participants in the Piedmont Health Study of the Elderly to estimate adjusted odds ratios for suicide and self-reported, physician diagnosed cancer, heart attack, stroke, and hip fracture.

RESULTS

Adjusting for all other factors, there was a statistically significant association of suicide and cancer (odds ratio [OR] 2.62, 95% confidence interval [CI] CI 1.84-3.73), but not heart attack, hip fracture, or stroke. The risk of suicide was also elevated for men vs. women (OR 17.15, CI 10.88-27.02), whites vs. blacks (OR 9.70, CI 6.07-15.50), and individuals with stressful life events (OR 2.75, CI 1.97-3.86) or limitations of instrumental (OR 2.93, CI 2.03-4.22) but not physical activities of daily living. Suicide cases were not more likely to be short of breath or poor sleep quality. Suicide was statistically significantly less likely for study participants who were married with spouse living vs. other (OR 0.61, CI 0.43-0.88) or who had one or more indicators of social support (OR 0.27, CI 0.19-0.39).

CONCLUSION

After adjustment for other risk factors, suicide was strongly associated with cancer but not with other disabling, potentially fatal conditions.

Suicidal ideation in prostate cancer survivors: understanding the role of physical and psychological health outcomes

BACKGROUND

Epidemiological studies have shown prostate cancer (PC) survivors are at an increased risk of suicide compared with the general population, but to the authors' knowledge very little is known regarding what factors are associated with this increased risk. The current study examined the prevalence of suicidal ideation (SI) and its association with cancer treatment and posttreatment physical and emotional health in a cohort of long-term PC survivors.

METHODS

A total of 693 PC survivors (3-8 years after diagnosis) completed a mailed survey on physical and psychological functioning, including cancer treatments, the Short Form-12 (SF-12), the Expanded Prostate Cancer Index Composite Instrument (EPIC-26), a depression rating scale, and 8 items regarding recent suicidal thoughts and behaviors.

RESULTS

A total of 86 PC survivors (12.4%) endorsed SI, with 10 individuals (1.4%) reporting serious SI. Serious SI was more common in this sample compared with age-adjusted and sex-adjusted normative data. SI was not associated with most demographic variables, or with PC stage or treatments. However, SI was found to be significantly associated with employment status, poor physical and emotional functioning, greater symptom burden on the EPIC-26, higher frequency of significant pain, and clinically significant depression (P < .01). In an adjusted logistic model, poor physical and emotional function, including disability status and pain, were found to be associated with SI (P < .05), even after adjusting for depression.

CONCLUSIONS

A significant percentage of PC survivors report recent SI, which is associated with both physical and psychological dysfunction, but not PC treatments. The results of the current study help to explain the increased risk of suicide previously reported in PC survivors and have important implications for identifying and treating those survivors at greatest risk of suicidality.

A correlational study of suicidal ideation with psychological distress, depression, and demoralization in patients with cancer

PURPOSE

This study aims to study the effects of depression and demoralization on suicidal ideation and to determine the feasibility of the Distress Thermometer as a screening tool for patients with cancer who experience depression and demoralization, and thus to establish a model screening process for suicide prevention.

METHODS

Purposive sampling was used to invite inpatients and outpatients with lung cancer, leukemia, and lymphoma. Two hundred participants completed the questionnaire, which included the Distress Thermometer (DT), Patient Health Questionnaire-9 (PHQ-9), Demoralization Scale-Mandarin Version (DS-MV), and Beck Scale for Suicide Ideation. All data obtained were analyzed using SPSS 18.0 and SAS 9.3.

RESULTS

Tobit regression analysis showed that demoralization influenced suicidal ideation more than depression did (t = 2.84, p < 0.01). When PHQ-9 ≥ 10 and DS-MV ≥42 were used as criteria for the DT, receiver operating characteristic analysis revealed that the AUC values were 0.77-0.79, with optimal cutoff points for both of DT ≥5; sensitivity 76.9 and 80.6 %, respectively; and specificity of 73.9 and 72.2 %, respectively.

CONCLUSIONS

Demoralization had more influence on suicidal ideation than depression did. Therefore, attention should be paid to highly demoralized patients with cancer or high demoralization comorbid with depression for the purposes of suicide evaluation and prevention. The DT scale (with a cutoff of ≥5 points) has discriminative ability as a screening tool for demoralization or depression and can also be used in clinical settings for the preliminary screening of patients with cancer and high suicide risk.

A review of cognitive therapy in acute medical settings. Part II: strategies and complexities

OBJECTIVE

Cognitive therapy (CT) has considerable utility for psychosomatic medicine (PM) in acute medical settings but, to date, no such cohesive adaptation has been developed. Part I delineated a CT model for acute medical settings focusing on assessment and formulation. In Part II, we review how CT can be applied to common PM clinical challenges. A pragmatic approach is helpful because this review targets PM trainees and educators.

METHODS

Narrative review is used to discuss the application of CT strategies to common challenges in acute medical settings. Treatment complexities and limitations associated with the PM setting are detailed. Exemplary dialogues are used to model techniques.

RESULT

We present CT approaches to eight common scenarios: (1) distressed or hopeless patients; (2) patients expressing pivotal distorted cognitions/images; (3) patients who catastrophize; (4) patients who benefit from distraction and activation strategies; (5) panic and anxiety; (6) suicidal patients; (7) patients who are stuck and helpless; (8) inhibited patients. Limitations are discussed.

SIGNIFICANCE OF RESULTS

A CT informed PM assessment, formulation and early intervention with specific techniques offers a novel integrative framework for psychotherapy with the acutely medically ill. Future efforts should focus on dissemination, education of fellows and building research efficacy data.

Association between suicidal ideation and behavior, and depression, anxiety, and perceived social support in cancer patients

Background

The aim of this study was to determine the relationship between suicidal behavior and associated factors such as depression, anxiety, and perceived social support level in cancer patients.

Material/Methods

The study group included 102 patients who were under treatment in the oncology department and the control group included 100 individuals with similar sociodemographic features. A sociodemographic information form, Beck depression inventory, Beck anxiety inventory, suicidal behavior inventory, suicidal ideation inventory, and multidimensional inventory of perceived social support were used.

Results

The mean Beck depression inventory and Beck anxiety inventory scores in the study group were significantly higher compared to the control group. Thirteen patients in the study group attempted suicide, whereas 3 individuals attempted suicide in the control group. Similarly, the mean suicide behavior and ideation scores in the study group were significantly higher compared to the control group. The mean total multidimensional inventories of perceived social support score, as well as the mean family and friend sub-inventory scores in the control group were significantly higher compared to the study group.

Conclusions

This study revealed that depression and anxiety occur frequently in cancer patients. Suicide attempts and ideation are higher in cancer patients compared to the control group. Social support perceived from family and friends is lower in cancer patients. Suicide attempts are correlated with depression, anxiety, low level of perceived social support, and advanced disease stage.

Are there specific health-related factors that can accentuate the risk of suicide among men with prostate cancer?

Purpose

The aim of this study was to explore if there were some specific factors pertinent to health-related quality of life (HRQoL) that could affect self-experienced suicide ideation in men with prostate cancer (PCa).

Methods

Questionnaires containing 45 items were distributed to members of the Swedish Prostate Cancer Federation in May 2012. Out of 6,400 distributed questionnaires, 3,165 members (50 %) with PCa completed the questionnaires. Those members expressed their experienced HRQoL and experienced suicide ideation using VAS-like scales as well as multiple-choice questions. Both descriptive and analytical statistical methods were employed. A regression model was used to explore the relationship between experienced health-related quality of life and experienced suicide ideation.

Results

Generally, the respondents rated their self-experienced health-related quality of life as good. About 40 % of the participants had experienced problem with incontinence, and 23 % had obstructions during miction. About 7 % of the respondents experienced suicidal ideation, at least sometime. The regression model showed statistically significant relationships between suicide ideation, on the one hand, and lower self-rated health-related quality of life (P < 0.001), physical pain (P = 0.04), pain during miction (P = 0.03), and low-rated mental / physical energy (P = 0.03), on the other.

Conclusion

It is quite necessary to know which specific disease and treatment-related problems can trigger suicide ideations in men with prostate cancer and to try to direct treatment, care, and psychosocial resources to alleviate these problems in time.

Psychosocial therapies for patients with cancer: a current review of interventions using psychoneuroimmunology-based outcome measures

BACKGROUND

As part of a new standard of quality cancer care, the Institute of Medicine has recommended inclusion of therapies that address psychosocial needs of cancer patients. A range of psychosocial therapies for managing acute and chronic stress have been developed for patients with cancer, based on the scientific framework of psychoneuroimmunology (PNI). The current review aimed to identify studies of new and emerging PNI-based psychosocial therapies in patients with cancer that have used neuroendocrine-immune biomarkers as outcomes. Specifically, this review aimed to evaluate studies based on the cancer populations involved, types of psychosocial therapies, and PNI measures employed.

METHOD

Methodology was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The PubMed, EMBASE, PsychINFO, CINAHL, and Google Scholar online databases were searched using combinations of keywords obtained from previous reviews of psychosocial interventions. Studies from 2001 to 2012 were included if they ( : ) were published in English, ( : ) used experimental or quasi-experimental designs, ( : ) evaluated psychosocial therapies, ( : ) involved cancer patients, and ( : ) reported results on at least one neuroendocrine or immune outcome measure. The search strategy identified 403 records and 2 stages of screening were used to eliminate irrelevant studies.

RESULT

A total of 24 cancer-specific studies of psychosocial therapies that used PNI-based outcome measures were included in this review. Most studies included early-stage breast cancer patients, and 2 major types of therapies emerged, cognitive-behavioral therapies and complementary medical therapies. Durations of interventions ranged widely, from 1.3 hours over a single week to 27 hours over 18 weeks. Considerable diversity in PNI outcomes made statistical comparisons problematic. Studies of cognitive-behavioral therapies were found to have reported the most success in impacting PNI-based measures, which were typically functional measures of the immune system, for example, cytokines.

CONCLUSION

Several issues related to research methodology are discussed. Most important, studies examining dose-response associations and resource allocation are needed to guide future research. A standardized panel of psychosocial instruments and biomarkers for PNI-based studies would enhance comparability of findings across studies when evaluating this body of research and assist with integrating psychosocial therapies into the standard of cancer care.

Premises and evidence in the rhetoric of assisted suicide and euthanasia

In debates about euthanasia and assisted suicide, it is rare to find an article that begins with an expression of neutral interest and then proceeds to examine the various arguments and data before drawing conclusions based upon the results of a scholarly investigation. Although authors frequently give the impression of being impartial in their introduction, they invariably reach their prior conclusions. Positions tend to be clearly dichotomized: either one believes that the practice of euthanasia or assisted suicide is totally acceptable or completely unacceptable in a just and moral society. Where there is some admission of a gray zone of incertitude, authors attempt to persuade us that their beliefs (preferences) are the only sensible way to resolve outstanding dilemmas. The practice of vehemently promoting a "pro" or "con" position may be useful when societies must decide to either legalize certain practices or not. Although only a handful of countries have thus far accepted the legal practice of euthanasia or assisted suicide (Belgium, Luxembourg, The Netherlands, the U.S. states of Montana, Oregon, Vermont and Washington, and Switzerland), scholarly articles in recent trends mainly promote legalization, to the point of recommending expansion of the current practices. Is this a case of the philosophers being ahead of their time in promoting and rationalizing the wave of the future? Alternatively, does the small number of countries that have legalized these practices indicate a substantial gap between the beliefs and desires of common citizens and the universe of the 'abstracted realm'? For the time being, what we do know is that more countries and states are debating legalization of euthanasia or assisted suicide, the nature of laws and legal practices vary greatly and both ethical and empirical assessments of current practices are the subject of much controversy. This article presents an examination of the premises and evidence in the rhetoric of assisted suicide and euthanasia. Inasmuch as any analysis cannot be totally impartial, we do not contend that our analysis is without influence from our experiences and philosophical affinities. Notwithstanding this caveat, we venture to propose that our scrutiny of the arguments and empirical data may offer some guidance to individuals who are attempting to reach practical conclusions based upon the available evidence, whether empirical or rationalized.

Suicidal ideation and risk factors in primary care patients with anxiety disorders

The presence of an anxiety disorder is associated with greater frequency of suicidal thoughts and behaviors. Given the high personal and societal costs of suicidal behaviors, suicide prevention is a priority. Understanding factors present within individuals with anxiety disorders that increase suicide risk may inform prevention efforts. The aims of the present study were to examine the prevalence of suicidal ideation and behaviors, as well as factors associated with suicide risk in patients with anxiety disorders in primary care. Data from a large scale randomized controlled study were analyzed to assess prevalence of suicidal thoughts and behaviors, as well as factors associated with suicide risk. Results revealed that suicidal ideation and behaviors were relatively common in this group. When examining mental and physical health factors jointly, presence of depression, mental health-related impairment, and social support each uniquely accounted for variance in suicide risk score. Methodological limitations include cross-sectional data collection and lack of information on comorbid personality disorders. Moreover, patients included were from a clinical trial with exclusion criteria that may limit generalizability. Results highlight the complex determinants of suicidal behavior and the need for more nuanced suicide assessment in this population, including evaluation of comorbidity and general functioning.

Behavioral Activation and Problem-Solving Therapy for Depressed Breast Cancer Patients

Major depressive disorder (MDD) is the most common psychiatric disorder in breast cancer patients. The prevalence of suicidal ideation in breast cancer patients is considerable, and relative to the general population, the prevalence of completed suicide is elevated, particularly in cancer patients with MDD. A major component of suicide prevention is effective treatment of MDD. Although some research has explored the utility of psychotherapy with breast cancer patients, only three trials have explored the benefits of behavior therapy in patients with well-diagnosed MDD and there has been no systematic investigation of the potential benefits of psychotherapy toward reducing suicidal ideation in breast cancer patients. As a follow-up to a recently completed randomized trial, this study examined the efficacy of 8 weeks of behavioral activation treatment for depression (BATD) and problem-solving therapy (PST) in reducing depression and suicidal ideation, as well as increasing hopefulness in breast cancer patients with MDD ( n = 80). Across both treatments, GEE analyses revealed decreased depression and suicidal ideation and increased hopefulness at posttreatment, results that were maintained at 12-month follow-up. Moreover, follow-up patient contact at approximately 2 years posttreatment yielded no indication of completed suicide. Although these data are preliminary, BATD and PST may represent practical approaches to decrease suicidal ideation in depressed breast cancer patients.

Religion and suicide in patients with mental illness or cancer

In Switzerland, the highest rates of suicide are observed in persons without religious affiliation and the lowest in Catholics, with Protestants in an intermediate position. We examined whether this association was modified by concomitant psychiatric diagnoses or malignancies, based on 6,909 suicides (ICD-10 codes X60-X84) recorded in 3.69 million adult residents 2001-2008. Suicides were related to mental illness or cancer if codes F or C, respectively, were mentioned on the death certificate. The protective effect of religion was substantially stronger if a diagnosis of cancer was mentioned on the death certificate and weaker if a mental illness was mentioned.

Increase of suicide and accidental death after hematopoietic stem cell transplantation: a cohort study on behalf of the Late Effects Working Party of the European Group for Blood and Marrow Transplantation (EBMT)

BACKGROUND

Relapse and transplant-related complications are leading causes of mortality after hematopoietic stem cell transplantation (HSCT). Suicides and accidents have not been studied in these patients. This study sought to determine whether there is an excess of suicide and accidental deaths after HSCT, and to determine risk factors.

METHODS

The incidence of suicidal and accidental death in patients after undergoing HSCT, standardized mortality ratio (SMR), and absolute excess risk (AER) of suicide and accidental deaths was determined, compared with the general European population. A case-control analysis was done to define factors associated with suicide and accidental deaths. Data were derived from the European Group for Blood and Marrow Transplantation Registry, including 294,922 patients who underwent autologous or allogeneic HSCT from 1980 to 2009.

RESULTS

The 10-year cumulative incidence of suicide and accidental deaths was 101.8 and 55.6 per 100,000 patients, respectively. SMR and AER of suicide after HSCT were 2.12 (P < .001) and 10.91, higher than in the European general population for 100,000 deaths, respectively. SMR and AER of accidental death were 1.23 (P < .05) and 2.54, respectively. In the case-control study, relapses were more frequent among patients who committed suicide after autologous HSCT (37% versus 18%; P < .0001). Chronic graft-versus-host disease was higher among patients who committed suicide after allogeneic HSCT (64% versus 37%; P = .001).

CONCLUSIONS

There is an excess of deaths due to suicide and accidents in patients after undergoing HSCT as compared with the European general population. Relapse was associated with more suicide and accidental deaths after autologous HSCT, and chronic graft-versus-host disease was associated with more deaths by suicide after allogeneic HSCT.

Ask suicide-screening questions to everyone in medical settings: the asQ'em Quality Improvement Project

BACKGROUND

Suicide in hospital settings is a frequently reported sentinel event to the Joint Commission (JC). Since 1995, over 1,000 inpatient deaths by suicide have been reported to the JC; 25% occurred in non-behavioral health settings. Lack of proper "assessment" was the leading root cause for 80% of hospital suicides. This paper describes the "Ask Suicide-Screening Questions to Everyone in Medical Settings (asQ'em)" Quality Improvement Project. We aimed to pilot a suicide screening tool and determine feasibility of screening in terms of prevalence, impact on unit workflow, impact on mental health resources, and patient/nurse acceptance.

METHODS

We piloted the asQ'em two-item screening instrument that assesses suicidal thoughts and behaviors, designed specifically for nurses to administer to medical patients. Educational in-services were conducted. A convenience sample of adult patients, 18 years or older, from three selected inpatient units in the National Institutes of Health Clinical Center, participated.

RESULTS

A total of 331 patients were screened; 13 (4%) patients screened "positive" for suicide risk and received further evaluation. No patient had acute suicidal thoughts or required an observational monitor. Screening took approximately 2 minutes; 87% of patients reported feeling comfortable with screening; 81% of patients, 75% of nurses, and 100% of social workers agreed that all patients in hospitals should be screened for suicide risk.

DISCUSSION

Nurses can feasibly screen hospitalized medical/surgical patients for suicide risk with a two-item screening instrument. Patients, nurses, and social workers rated their experience of screening as positive and supported the idea of universal suicide screening in the hospital.

Randomized controlled trial of standardized education and telemonitoring for pain in outpatients with advanced solid tumors

Purpose

Previous studies have not defined the role of telemonitoring with educational tools in outpatients with advanced cancers. We tested the effectiveness of standardized education and telemonitoring for improving pain, distress, anxiety, depression, quality of life (QoL), and performance in outpatients with advanced cancers.

Methods

A total of 108 patients were randomly assigned to receive pain education alone (control arm) or pain education plus telemonitoring (experimental arm). Nursing specialists provided video-assisted educational material in both arms and daily telemonitoring for the first week in the experimental arm. Assessment was performed at baseline and 1 week and included evaluations of pain (Brief Pain Inventory, BPI), distress (Distress Thermometer, DT), anxiety, and depression (Hospital Anxiety and Depression Scale, HADS), QoL (QLQ-C30), and a Karnofsky score.

Results

Overall (n = 108), pain intensity was significantly improved at 1 week, including worst pain (7.3 to 5.7, P < 0.01) and average pain (4.6 to 3.8, P < 0.01). Additionally, anxiety (HADS score ≥ 11, 75 % to 56 %, P < 0.01), depression (HADS score ≥ 11, 73 % to 51 %, P < 0.01), QoL (fatigue and insomnia), and the Karnofsky score (32 to 66, P < 0.01) were also significantly improved at 1 week. However, the level of distress did not improve. The telemonitoring plus standardized education group showed more significant improvement in portion of pain >4 on VAS scale (35 % vs. 19 %, P = 0.02).

Conclusions

Standardized pain education using nursing specialists is an efficient way to improve not only pain itself but also anxiety, depression, performance, and QoL. The addition of telemonitoring helps to improve pain management in the outpatient setting.

Comparative Risk Factors for Accidental and Suicidal Death in Cancer Patients

Background: Cancer patients appear at higher risk of accidental death and suicide. The reasons for this and how suicide and accidental death relate remain unclear. Aims: To clarify and contrast risk factors for such deaths among cancer patients. Methods: A SEER (1973–2007) analysis was conducted on 4,449,957 cancer patients comparing all causes of death (COD) to accidental and suicidal deaths through competing hazards, relative risk and proportional hazards models. SEER did not provide psychological assessments; the analysis was confined to their standard epidemiological and clinicopathological parameters. Results: 2,557,385 overall deaths yielded 16,879 (0.66%) accidents and 6,589 (0.26%) suicides. Mortality reached its highest incidence immediately after diagnosis and obeyed Pareto type II distributions. The major identifiable risk factor for suicide was male gender; for accidental death, First Nations ethnicity; and all COD, metastases. Minor factors for suicide included metastases, advanced age, and respiratory as well as head and neck tumors, whereas for accidental death they were male gender, metastases, advanced age, and brain tumors. Conclusions: Differences were observed in the risk patterns of suicide and accidental death, suggesting distinct etiologies. A high incidence of suicides and accidental deaths following diagnosis (attributed by some to stress from the diagnosis of cancer) correlated here with overall mortality and indicators of physical morbidity. Cancer patients with the above identifiable risk factors warrant supportive attention.

Suicide and non-suicide mortality after self-harm in Taipei City, Taiwan

BACKGROUND

Most previous studies of long-term mortality risk following self-harm have been conducted in Western countries with few studies from Asia.

AIMS

To investigate suicide and non-suicide mortality after non-fatal self-harm in Taipei City, Taiwan.

METHOD

Prospective cohort study (median follow-up 3.3 years) of 7601 individuals presenting to hospital with self-harm (January 2004 to December 2006). Standardised mortality ratios (SMRs) for suicide and non-suicide mortality were calculated.

RESULTS

Suicide risk in the year following self-harm was over 100 times higher than in the general population (SMR = 119.6, 95% CI 99.6-142.5). Males and middle-aged and older adults had the highest subsequent risk of suicide. Compared with people who took an overdose, individuals who used hanging or charcoal burning in their index episode had the highest risk of suicide. For non-suicide mortality the SMRs were 6.7 (95% CI 5.7-7.8) in the first year and 4.4 (95% CI 3.9-4.9) during the whole follow-up period.

CONCLUSIONS

Patterns of increased all-cause and suicide mortality following an episode of self-harm are similar in Taipei City to those seen in Western countries. Designing better aftercare following non-fatal self-harm, particularly for those with underlying physical disorders or who have used lethal self-harm methods, should be a priority for suicide prevention programmes in Asia.

Death ideation in cancer patients: contributing factors

Advances in cancer research and therapy have improved prognosis and the quality of life of many patients. However, previous epidemiological studies in oncologic patients have shown an increased risk of suicide. Suicidal thoughts, relatively well known in those terminally ill, may be just as important for cancer patients who are survivors or are living with the disease. Nonetheless, there is a relative paucity of data about suicidality in this setting. The authors conducted a prospective observational study to identify death thoughts and to explore the factors associated with suicidal ideation in cancer patients. A sample of 130 patients referred for psychiatric consultation was obtained following informed consent and authorization from the local ethics committee. A semistructured interview assessed sociodemographic data, psychosocial support, and information regarding the cancer process and its treatment. Psychometric instruments were used to evaluate psychopathology, namely the Hospital Anxiety and Depression Scale, the Beck Hopelessness Scale, and the Beck Scale for Suicide Ideation. Psychiatric diagnoses were obtained through the application of the Mini International Neuropsychiatric Interview. Death ideation was identified in 34.6% of patients, yet only 10% had active suicidal thoughts. Risk of suicide was associated with female gender, a psychiatric diagnosis (major depressive disorder, panic disorder, or dysthymia), difficult interpersonal relationships, associated pain, high hopelessness, and depressive and anxiety symptoms. Although suicidal thoughts are frequent in cancer patients at different stages of disease, most are transitory. Risk factors for suicidal ideation have been identified, such as depression, hopelessness, uncontrolled pain, and difficult interpersonal relationships. Further assessment is necessary to identify those at higher risk of attempting suicide, and underlying psychiatric disorders should be vigorously treated.

Lifetime suicidal ideation and attempt are common among HIV+ individuals

BACKGROUND

Estimates of the prevalence of lifetime suicidal ideation and attempt, and risks for new-onset suicidality, among HIV-infected (HIV+) individuals are not widely available in the era of modern combined antiretroviral treatment (cART).

METHOD

Participants (n=1560) were evaluated with a comprehensive battery of tests that included the depression and substance use modules of the Composite International Diagnostic Interview (CIDI) and the Beck Depression Inventory-II (BDI-II) as part of a large prospective cohort study at six U.S. academic medical centers. Participants with possible lifetime depression (n=981) were classified into five categories: 1) no thoughts of death or suicide (n=352); 2) thoughts of death (n=224); 3) thoughts of suicide (n=99); 4) made a suicide plan (n=102); and 5) attempted suicide (n=204).

RESULTS

Twenty-six percent (405/1560) of participants reported lifetime suicidal ideation and 13% (204/1560) reported lifetime suicide attempt. Participants who reported suicidal thoughts or plans, or attempted suicide, reported higher scores on the BDI-II (p<0.0001), and higher rates of current major depressive disorder (p=0.01), than those who did not. Attempters reported higher rates of lifetime substance abuse (p=0.02) and current use of psychotropic medications (p=0.01) than non-attempters.

LIMITATIONS

Study assessments focused on lifetime, rather than current, suicide. Data was not collected on the timing of ideation or attempt, frequency, or nature of suicide attempt.

CONCLUSIONS

High rates of lifetime suicidal ideation and attempt, and the relationship of past report with current depressed mood, suggest that mood disruption is still prevalent in HIV. Findings emphasize the importance of properly diagnosing and treating psychiatric comorbidities among HIV persons in the cART era.

Psychosocial care in cancer

Psychosocial care for cancer patients historically has been overlooked as an aspect of quality clinical care. However, several organizations have recently made strong recommendations for inclusion of psychosocial care across the continuum of treatment, from diagnosis, through treatment, into survivorship, and in the palliative stages of care. The evidence base for screening, diagnosis, and effective treatment of psychosocial issues in the context of cancer care is growing. Recent highly relevant research covering major topics in psycho-oncology, including distress, delivery of care, psychoneuroimmunology, and cognitive deficits related to cancer, is reviewed in this article.

Suicide in cancer patients in California, 1997-2006

The objective of this study was to measure suicide risk in cancer patients and compare it with the general population. Suicide rates were based on 1,168 suicides in 1,123,528 cancer patients in California from 1997-2006 and were studied by race/ethnicity, sex, site, stage, and marital status. Suicide in cancer patients is 2.3 times the general population with 81% in the non-Hispanic Whites, and half within the first 2 years post diagnosis. In men, it rapidly increases by age to a high plateau in the early forties. Metastatic cancers and those of the prostate, lung and bronchus, pancreas, stomach, esophagus, and oral cavity in men and breast in women were associated with significantly higher risk. Cancer patients are at higher risk of suicide and should be specifically targeted for preventive efforts post diagnosis.

Association of sedative-hypnotic medications with suicidality

Evaluation of: Brower KJ, McCammon RJ, Wojnar M, Ilgen MA, Wojnar J, Valenstein M. Prescription sleeping pills, insomnia, and suicidality in the National Comorbidity Survey Replication. J. Clin. Psychiatry DOI: 10.4088/JCP.09m05484gry (2010) (Epub ahead of print). Several studies have investigated the association between sedative-hypnotics and suicidality, as such medications not only serve as a method for suicide, but are also involved in the usual options for treating psychiatric and medico-surgical disorders. According to population-based studies in Europe, Asia and the USA, sedative-hypnotic medications were significantly associated with suicide. However, these studies failed to address psychiatric comorbidities, new hypnotic medications, such as zolpidem, and the specific times at which such medications were used. Recently, Brower and colleagues have investigated the association of the prescription of sedative-hypnotic drugs with suicidality, to determine whether such medications were associated with suicidal ideation, suicide plans and suicide attempts in a large-cohort sample. They found that the use of sedative-hypnotic medications was significantly associated with suicidal ideation, suicide plans and suicide attempts. In addition, the use of sedative-hypnotic medications was a stronger predictor than insomnia of both suicidal ideation and suicide attempts. This article will discuss the relationship between prescription of sedative-hypnotic medications and suicide in the context of the potential limitations and significance of this recent research.

Validación del Inventario Breve de Síntomas (BSI-18) en mujeres mexicanas diagnosticadas con cáncer de mamaValidación del Inventario Breve de Síntomas (BSI-18) en mujeres mexicanas diagnosticadas con cáncer de mama

El distrés es una experiencia emocional desagradable que puede afectar al afrontamiento y curso de una enfermedad oncológica. El Inventario Breve de Síntomas (BSI-18) es usado frecuentemente en pacientes oncológicos para medir distrés. No obstante, su estructura factorial no está bien establecida, y sus propiedades métricas no han sido estudiadas con muestras mexicanas. La presente investigación tiene como objetivos estudiar la distribución, discriminabilidad y homogeneidad de los ítems del BSI-18, estimar la consistencia interna del BSI-18, determinar su estructura factorial y calcular la validez convergente, discriminante y consistencia interna de sus factores. Se recolectó una muestra intencional de 203 mujeres con cáncer de mama en tratamiento oncológico. Todas ellas eran adultas tratadas en la ciudad de Monterrey, México. Todos los ítems del BSI-18 resultaron discriminativos y consistentes. Sus distribuciones mostraron mayor concentración en valores bajos. La consistencia interna de la escala fue alta (α de Cronbach=0,888). El modelo de un factor general de distrés con tres factores jerarquizados (depresión, síntomas simpáticos de ansiedad y síntomas vasovagales de ansiedad) mostró las mejores propiedades de bondad de ajuste. También sus factores tuvieron las mejores propiedades de validez convergente y consistencia interna. Además, este modelo permitió superar los problemas de validez discriminante entre los factores. Se concluye que, en la población estudiada de mujeres diagnosticadas con cáncer, se pueden retener todos los ítems del BSI-18, y la escala resultó consistente y válida desde un modelo jerarquizado de tres factores.
