Other studies focused the attention on tumor markers already used for the diagnosis of other solid tumors, such as the salivary levels of the carcino-embryonic antigen (CEA; 68.9% sensitivity, 73.3% specificity) [23], carcinoantigen 19-9 (CA19-9; no diagnostic value) [24] and CA125 (80.0% sensitivity, 66.0% specificity) [25]. The gene discussed is CEACAM5; the disease is neoplasm.
