Abstract:
Objective:To investigate the diagnostic value of vaginal color Doppler flow parameters in patients with epithelial ovarian cancer in different FIGO staging.Methods:178 patients with ovarian tumors who were treated by surgery in Dingzhou People’s Hospital from Jul. 2016 to Jul. 2022 were selected, and they were divided into ovarian cancer group (65 cases) and ovarian cyst group (113 cases) according to the results of postoperative pathological diagnosis. According to FIGO staging standards, ovarian cancer was divided into FIGO stage I (18 cases) , FIGO stage II (16 cases) , FIGO stage III (16 cases) and FIGO stage IV (15 cases) . The blood flow parameters of vaginal color Doppler ultrasound were measured, including arterial pulsatility index (PI) , end diastolic flow velocity (EDV) , resistance index (RI) , peak flow velocity (PSV) , serum vascular endothelial growth factor (VEGF) and human epididymal epithelial secretory protein 4 (HE4) . The levels of PI, EDV, RI, PSV, VEGF and HE4 were compared between the two groups and patients with different FIGO stages, and the value of ROC analysis of vaginal color Doppler flow parameters in predicting the occurrence of ovarian cancer was analyzed. The correlation between FIGO stage and vaginal color Doppler flow parameters and serum VEGF and HE4 levels was analyzed by person coefficient.Results:PI and RI levels in ovarian cancer group were (0.79 ± 0.15) , and (0.39 ± 0.12) , lower than those in ovarian cyst group (1.51 ± 0.17) , (0.72 ± 0.16) ; EDV, PSV, HE4, VEGF levels were (13.88 ± 4.18) cm/s, (25.61 ± 4.53) cm/s, (283.92 ± 28.97) pmol/L, and (372.55 ± 38.96) ng/mL, higher than those in ovarian cyst group ( P<0.05) . According to ROC analysis, the best cutoff values of transvaginal color Doppler blood flow parameters for predicting the occurrence of ovarian cancer were PI<1.235, EDV≥10.985 cm/s, RI<0.580, PSV≥22.975cm/s, all P<0.05. The levels of PI and RI in patients with different FIGO stages showed a decreasing trend with the increase of the severity of the disease, while the levels of EDV, HE4 and VEGF showed an increasing trend ( P<0.05) . There was no significant difference in PSV levels between patients with different FIGO stages ( P>0.05) . The correlation analysis showed that FIGO stage was positively correlated with the blood flow parameters EDV and the levels of serum HE4 and VEGF. FIGO stage was negatively correlated with PI and RI ( P<0.05) . Conclusions:There were significant differences in the levels of PI, RI and EDV in patients with ovarian cysts and ovarian cancer at different FIGO stages. The levels of PI, RI and EDV are closely related to the malignant degree of ovarian cancer.
