[The presence of CEA in spinocellular carcinoma of the oral cavity].
Using an immunoperoxidase method the Authors have demonstrated carcinoembryonic antigen (CEA) in 4/7 patients with benign oral lesion and in 9/10 patients with oral cancer. All 4 oral leukoplakias were positive for CEA. The histologic presence of CEA in oral cancer was related mainly to the formation of well differentiated tissue. The anaplastic carcinoma was negative. These findings indicate that CEA is a product of differentiated cells and should not be considered exclusively an oncofetal antigen or a marker of undifferentiated cells.
