Immunocytochemical detection of carcinoembryonic antigen in salivary gland tumors.
The immunoperoxidase method was applied for carcinoembryonic antigen (CEA) detection in biopsy specimens of salivary gland tumors. 9 out of 10 adenoidcystic carcinomas revealed a strong and abundant reaction in tumoral glands. 10 other specimens of pleomorphic adenomas showed weak staining in the areas of epithelial proliferation. Normal glands adjacent to the tumor mass revealed a weak but constant reaction on the luminal border. As in other types of gland tumor, the quantitative estimation of CEA production by salivary gland tumors may be useful in the monitoring of recurrencies.
