ABDOMINAL COMPUTED TOMOGRAPHY WITH SERUM CEA AND CA-125 MARKERS IN OVARIAN TUMORS

Abstract Most studies on the cystic component of ovarian tumors have been aimed at determining tumor biomarkers, with CA-125 and CEA being the most commonly studied tumor markers. The CEA content in the cystic component of the tumor is increased in mucinous type ovarian tumors although it can be increased in both cystadenoma and cystadenocarcinoma. The CEA value was found to be highest in tumor cystic fluid, followed by ascites fluid, then lowest in blood. 46 Different things were found in the tumor marker CA-125, where higher concentrations of this biomarker were found in serous type ovarian tumors compared to mucinous types, although several other studies have shown that the opposite is true. Another study also reported that there was no difference in the concentration of the tumor marker CA-125 in benign or malignant ovarian tumors. 46 Attenuation value (Hounsfield Unit) of soft tissue on Abdominal Computed Tomography. The attenuation value of x-ray beams on CT (computed tomography) is very dependent on the thickness and anatomical composition of the soft tissue that affects it.
