[Changes in neurohumoral factors of various tissues in patients with breast cancer].
Such neurohumoral factors of antitumor resistance regulation as catecholamines, corticosteroids and cholinergic mechanisms were studied in tissues of breast cancer patients. Tissue adjacent to tumor revealed elevated concentrations of 11-hydroxycorticosteroids and adrenaline matched by an increased release of norepinephrine which greatly depended on weakened cholinergic influences. These disturbances were pronounced in stages I and II tumors and, particularly, in infiltrating scirrhous cancer. Disbalance in neurohumoral factor distribution between normal and altered tissues may boost tumor recurrence and metastatic spread.
