A preliminary study of CA15-3, c-erbB-2, epidermal growth factor receptor, cathepsin-D, and p53 in saliva among women with breast carcinoma.
A panel of markers used to aid in the diagnosis and treatment of breast cancer was examined in the saliva of a cohort of healthy women, women with benign lesions of the breast, and women with diagnosed breast cancer. We found recognized tumor markers c-erbB-2 (erb), cancer antigen 15-3 (CA15-3), and tumor suppressor oncogene protein 53 (p53) in the saliva of all three groups of women. The levels of erb and CA15-3 in the cancer patients evaluated, however, were significantly higher than the salivary levels of healthy control subjects and benign tumor patients. Conversely, pantropic p53 levels were higher in control subjects compared with those women with breast cancer and those with benign tumors. Although cathepsin-D and epidermal growth factor receptor were detected, they did not demonstrate any clear correlation with disease status. The results of the pilot suggest that these markers have potential use in initial detection and/or follow-up screening for the detection of breast cancer in women.
