Double role of depression in gastric cancer: As a causative factor and as consequence

Abstract

In this editorial we comment on the article “Hotspots and frontiers of the relationship between gastric cancer and depression: A bibliometric study”. Gastric cancer (GC) is a common malignancy in the digestive system with increased mortality and morbidity rates globally. Standard treatments, such as gastrectomy, negatively impact patients' quality of life and beyond the physical strain, GC patients face psychological challenges, including anxiety and depression. The prevalence of depression can be as high as 57%, among gastrointestinal cancer patients. Due to the advancements in treatment effectiveness and increased 5-year overall survival rates, attention has shifted to managing psychological effects. However, the significance of managing the depression doesn’t lie solely in the need for a better psychological status. Depression leads to chronic stress activating the sympathetic nervous system and the hypothalamus-pituitary-adrenal axis, leading release of catecholamines inducing tumor proliferation, migration, and metastasis, contributing to GC progression. The dysregulation of neurotransmitters and the involvement of various signaling pathways underscore the complex interplay between depression and GC. Comprehensive strategies are required to address the psychological aspects of GC, including region-specific interventions and increased monitoring for depression. Understanding the intricate relationship between depression and GC progression is essential for developing effective therapeutic strategies and improving overall outcomes for patients facing this complex disease. In this Editorial we delve into double role of depression in the pathogenesis of GC and as a complication of it.
