Prevalence and risk factors for suicidality in cancer patients and oncology healthcare professionals strategies in identifying suicide risk in cancer patients

Suicide risk following a new cancer diagnosis among Veterans in Veterans Health Administration care

BACKGROUND

Cancer diagnoses are associated with an increased risk for suicide. The aim of this study was to evaluate this association among Veterans receiving Veterans Health Administration (VHA) care, a population that has an especially high suicide risk.

METHODS

Among 4,926,373 Veterans with VHA use in 2011 and in 2012 or 2013, and without VHA cancer diagnoses in 2011, we assessed suicide risk following incident cancer diagnoses. Risk time was from initial VHA use in 2012-2013 to 12/31/2018 or death, whichever came first. Cox proportional hazards regression models evaluated associations between new cancer diagnoses and suicide risk, adjusting for age, sex, VHA regional network, and mental health comorbidities. Suicide rates were calculated among Veterans with new cancer diagnoses through 84 months following diagnosis.

RESULTS

A new cancer diagnosis corresponded to a 47% higher suicide risk (Adjusted Hazard Ratio [aHR] = 1.47, 95% CI: 1.33-1.63). The cancer subtype associated with the highest suicide risk was esophageal cancer (aHR = 6.01, 95% CI: 3.73-9.68), and other significant subtypes included head and neck (aHR = 3.55, 95% CI: 2.74-4.62) and lung cancer (aHR = 2.35, 95% CI: 1.85-3.00). Cancer stages 3 (aHR = 2.36, 95% CI: 1.80-3.11) and 4 (aHR = 3.53, 95% CI: 2.81-4.43) at diagnosis were positively associated with suicide risk. Suicide rates were highest within 3 months following diagnosis and remained elevated in the 3-6- and 6-12-month periods following diagnosis.

CONCLUSION

Among Veteran VHA users, suicide risk was elevated following new cancer diagnoses. Risk was particularly high in the first 3 months. Additional screening and suicide prevention efforts may be warranted for VHA Veterans newly diagnosed with cancer.

Suicide in obstructive lung, cardiovascular and oncological disease

Healthcare institutions face increasing demands stemming from the burden of noncommunicable diseases. The personal, social, financial and societal impact of these diseases are well-documented. However, the mental health concerns and trajectories of patients afflicted by chronic medical diseases have been under-recognized and are under-resourced. Despite that chronic diseases are associated with substantially increased risk of suicide, the medical world has largely failed to properly address suicide in the medically ill. Considering their high prevalence and mortality rate, this review article will highlight the mental health burden and suicide risk in obstructive lung, cardiovascular (including stroke) and oncological disease, in light of relevant data and conceptual models of suicide. Finally, general evidence-based suicide intervention strategies and potential selective adaptation of these strategies to the chronic medically ill patient populations and medical settings will be reviewed.

Suffering experiences of people with cancer undergoing chemotherapy: A meta-ethnographic study

This meta-ethnography had the objectives of identifying, evaluating, and summarizing the findings of qualitative studies regarding the suffering experiences of people undergoing chemotherapy, as well as developing an explanatory conceptual structure regarding what affects these experiences. A systematic literature review was carried out, covering the past 10 years, in the following databases: CINAHL, Embase, Medline, LILACS and Scopus. By using meta-ethnographic synthesis methods, the following themes were found: the pain of loss; evaluating, measuring, and neutralizing the threat; and social contours of suffering. The experience of living with cancer and undergoing chemotherapy was synthesized into a theoretical-explanatory model with a structure that resembles barbed-wire loops. The model expresses people's suffering experiences as marked by the feeling of loss, restraint of emotions, and resilience. While transcendent movements broke the cycle of suffering, resilience emerged as a learning experience that made patients more resistant to the pain of loss. The results indicated a complex and diverse set of factors that influence suffering, which confirmed that experiences are individual, comprehensive, and continuously reinterpreted.
