Abstract

Substantial evidence indicates that psychological stress can influence the incidence and progression of cancers, and adequate psychotherapies are beneficial to cancer patients. Recently, the mechanisms responsible for the effects of psychological stress on cancer cells have been extensively investigated at the systemic, biochemical and molecular levels. Accumulating data indicate that the effects of psychological stress on cancer cells are mainly mediated by key stress-related mediators and their corresponding receptors in multi-fold pathways: chronic stressors act on the paraventricular nucleus and the suprachiasmatic nuclei. The effects are then transmitted through the sympathetic nervous system and the hypothalamic-pituitary-adrenal axis, amplified by the unchecked release of stress-related mediators and altered behaviors. These mediators act as immunosuppressors or mitogens in the tumor micro-environment. The converging effects of psychological stress on cancer cells finally signal through receptors of the stress mediators and cytokines to activate the intracellular pro-proliferative and pro-migratory signaling pathways, and reset the molecular clock in tumor cells. Understanding these action mechanisms of psychological stress in promoting the growth and invasion of cancer cells is crucial for devising effective interventions.
