Clinical studies indicate that stress, chronic depression, social support and other psychological
factors may influence cancer progression. Recent studies have identified biological signalling
pathways that could contribute to such effects even if the influence of the stress on some
tumors is not yet well understood. Environmental and psycho-social processes initiate a cascade
of information-processing pathways in the central nervous system (CNS) and periphery, which
subsequently trigger fight-or-flight stress responses in the autonomic nervous system (ANS), or
defeat/ withdrawal responses produced by the hypothalamic–pituitary–adrenal axis (HPA). In
the figure 1 , are reported the areas of the brain thought to be responsible for mediating
stress responses and their effects on the adrenal glands and other target tissues. HPA
responses are mediated by hypothalamic production of corticotrophin releasing factor and
arginine vasopressin, both of which activate the secretion of pituitary hormones such as
adrenocorticotropic hormone (ACTH), enkephalins and endorphins. ACTH induces downstream
release of glucocorticoids such as cortisol from the adrenal cortex. Glucocorticoids control
growth, metabolism and immune function. We show that in mice which undergo to stress
condition of restraint one week before tumor injection of B16-F10 murine melanoma cell line, the
tumor burden increases of 200% respect to control group, and 120% in mice treated with

These data suggest that the stress influences the tumor progression and growth by activaction of β adrenergic
receptor and increases glucorticoids levels that induce a upregulation of VEGF and increase of eNOS levels. High
levels of eNOS induce expression of iNOS that produces an increase in VEGF expression and thymic atrophy by
induction of apoptosis of T cells. These finding suggest that the stress influences also tumors not “strictly”
hormone–dependent as melanoma. These mechanisms activated by the stress, help to understand new pathway
involved in tumor progression and could represent new strategies for protecting individuals with cancer from the
detrimental effects of stress biology on the progression of malignant disease. Our next goal is to discover new
drugs by double action in order to block tumor progression induced by stress, without somministration of more
drugs to the patient that could be dangerous in the time.
