Epidermal growth factor in plasma and saliva of patients with active breast cancer and breast cancer patients in follow-up compared with healthy women

Abstract

We measure EGF in saliva and plasma from 52 patients with active breast cancer, 22 breast cancer patients in follow-up (non-active) and 33 healthy women. EGF concentrations in saliva were significantly higher in patients with active and non-active breast cancer than healthy women, whereas the opposite results were found in plasma. The highest values of EGF in saliva were found in the local recurrence subgroup.
