Tumor markers are produced directly by the tumor or by non-tumor cells as a response to the presence of a tumor, which offers a putative clinical use in the screening, diagnosis and treatment of various cancers [15, 17].Our previous study has demonstrated that, a panel of three different ascitic tumor markers (ascitic CEA > 50.00 ng/mL or CA15-3 > 75.00 U/mL or CA19-9 > 200.00 U/mL) yielded a sensitivity of 85.45% and a specificity of 97.32% in the diagnosis of malignant or benign ascites [15]. Here, CEACAM5 is linked to neoplasm.
