Suicide Risk in Digestive Cancer Patients: A Systematic Review of Sociodemographic, Psychological, and Clinical Predictors

Résumé fourni par la source

A cancer diagnosis often triggers profound psychological and emotional distress as individuals reflect on existential issues such as life and death. The aim of this review was to provide estimates of suicide risk associated with digestive cancer worldwide, and to identify sociodemographic, psychological, and clinical factors associated with suicide risk in patients with digestive cancer. MATERIALS AND METHODS: The literature search was guided by the following question: What is the relationship between suicide and digestive cancer, and what sociodemographic, psychological, and clinical factors contribute to the risk of suicide in these patients? We searched PubMed, PsycINFO, Embase, CINAHL, and Web of Science, and systematically reviewed the evidence, according to PRISMA guidelines, from relevant articles on the association between digestive system cancers and suicide outcomes published over a 14-year period (2011-2024). Eligible studies were searched in the main scientific databases up to August 2024. RESULTS: There are many reasons why people die by suicide, including challenges faced by patients in mentally adapting to their new condition and physical illness. Studies have shown that the highest suicide rates in digestive cancer patients are observed in males, older age groups, single people, those with a poor cancer prognosis, and those with a lack of treatment provision (surgery or chemotherapy). The risk of suicide peaks at six months post-discrimination, remains stable for three years, and then declines. CONCLUSIONS: Systematic changes in cancer care, such as aggressive treatment of pain and physical symptoms, management of delirium and cognitive impairment, routine screening, increased monitoring, and proactive measures for high-risk patients, can play a critical role in preventing unnecessary deaths and addressing the increased vulnerability of cancer patients, underscoring the need for targeted psychological support and early intervention, especially during critical periods like diagnosis and post-treatment recovery.
