Mechanism of chronic stress to promote tumor development and the intervention.

Abstract

Chronic stress is a serial of non-specific neuroendocrine reactions in the body when stimulated by stressors for a long time, which has been shown to have a significant effect on tumor development. Chronic stress can activate the hypothalamus-pituitary-adrenal axis and the sense-adrenal myelin system, promote catecholamine and adrenal corticosteroid secretion, regulate the downstream pathways at all levels, and modulate the secretion of immune cells and immune factors, inhibit protective immune response, and induce inflammation, thus promoting tumor cell proliferation and metastasis. Some drugs and psychotherapy can alleviate the patient's stress state, block the nerve signal transmission at all levels of access, regulate the immune system, or can become an effective means to intervene in chronic stress in tumor patients for clinical treatment to provide reference for intervention ideas. However, due to lack of relevant clinical trials, the clinical intervention effect of various drugs and psychotherapy is uncertain and needs more studies to verify the effect.
