Diagnostic value of serum tumor markers for adnexal masses

ObjectiveThe study aim was to investigate the diagnostic value of measuring preoperative serum tumor markers in patients with adnexal masses.MethodsThe study included all (358) consecutive patients treated for adnexal tumors at the Clinic of Obstetrics and Gynecology, Clinical Center of Serbia during 12 months. Tumor-marker levels (Ca 125, CEA, HE 4, Ca 19.9 and Ca 15.3) obtained from all women on admission were compared with histopathological findings in cases in which tumors were removed.ResultsWomen with malignant tumors had the highest levels of Ca 125, CEA and HE 4 (p<0.01). Mucinous adenocarcinoma produced the highest amounts of Ca 19.9 and CEA. Ca 15.3 was the highest in women with endometrioid carcinoma. There were no significant differences in the levels of all serum tumor markers between women with benign and borderline tumors (p>0.05). Malignant forms of tumors were well indicated by Ca 125, HE 4 and Ca 15.3 levels. The combination of Ca 125 and HE 4 resulted in the highest sensitivity, specificity, and positive or negative predictive value (91.04%, 87.6%, 67.9%, 77.2%, respectively).ConclusionsBlood levels of tumor markers can be effective? predictors of the nature of adnexal masses. For the most precise evaluation, a combination of serum tumor markers should be used.
