The use of CA125, human epididymis protein 4 (HE4), risk of ovarian malignancy algorithm (ROMA), risk of malignancy index (RMI) and subjective assessment (SA) in preoperative diagnosing of ovarian tumors

Abstract

Objectives: To compare utility of CA125, human epididymis protein 4 (HE4), risk of ovarian malignancy algorithm (ROMA), risk of malignancy index (RMI) and subjective assessment (SA) in preoperative diagnosis of ovarian tumors. Material and methods: Research was conducted among 456 patients qualified for surgery due to ovarian tumor. Preoperatively, CA125 and HE4 serum levels were estimated, and transvaginal ultrasound was performed. ROMA and RMI values and SA qualifications were obtained. Results were compared with pathomorphological findings. Results: Receiver Operating Characteristic (ROC)-Area Under Curve (AUC) values for CA125, HE4, ROMA, RMI and SA in preoperative diagnosis of malignant lesions were 0.819, 0.909, 0.911, 0.895 and 0.895, respectively. Combinations of biochemical and sonographic methods increased sensitivity in diagnosis of ovarian tumors. Combinations utilizing serum HE4 concentrations were most useful. Conclusions: CA125, HE4, ROMA, RMI and SA proved to be useful in preoperative diagnosis of ovarian tumors. HE4 and ROMA occurred to be the most useful. Ultrasonographic methods are considerably useful in diagnosis of ovarian tumors. RMI and SA present similar overall diagnostic value
