Condition: Esophageal Cancer · Immunotherapy · Sponsor: Second Xiangya Hospital of Central South University
Chronic stress refers to a special emotional state caused by unexpected stress for a long time, with an increasing incidence in the population. It can cause the body to release hormones such as cortisol and adrenaline. Tumor patients often experience changes such as psychological and emotional abnormalities, decreased quality of life, and impaired social relationships. Under stimulation, patients often experience negative reactions such as anxiety or depression. Epidemiological studies have shown that stress can affect the prognosis of malignant tumors, but the effect of stress on the efficacy and prognosis of esophageal cancer is still unclear. In animal models, chronic stress leads to an increase in tissue catecholamine levels, increased tumor burden, and increased invasiveness of ovarian cancer cells in mouse models. At the same time, stress can promote tumor neovascularization in mice. However, the mechanism by which chronic stress affects the occurrence and development of esophageal cancer is currently unclear. In addition to neurohumoral factors, chronic stress can cause changes in the gut microbiota, which in turn affects the body's digestion, metabolism, and immune function. It is a key gatekeeper of the immune response to tumors. Therefore, gut microbiota as an intermediate factor may also affect the occurrence and prognosis of various types of esophageal cancer.
