- W2363420859 abstract "Objective The vascular pathologic basis of transvaginal three-dimensional color power angiography(TV3D-CPA) was studied to evaluate its value in identifying and staging ovarian tumors.Methods Sixty-one ovarian tumors (38 malignant ovarian tumors,5 borderline ovarian tumors,18 benign ovarian tumors) were examined preoperatively with TV3D-CPA.The vascularity type and vasculary index (VI) were assessed respectively.The specimens were stained immunohistochemically with anti-34 antibody and microvessel density (MVD) was calculated.The malignant ovarian tumors were staged according to FIGO,2000 standard.The relation between the indices (VI and MVD) and clinical stages were analyzed.Results Type Ⅲ of vascularity type were found in 78.9%(30/38) malignant ovarian tumors and (5.6%,1/18) benign ovarian tumors (P0.05).The sensitivity and specificity of using type Ⅲ to diagnose malignant ovarian tumors were 78.9% and 86.9%,respectively.VI and MVD in 38 malignant ovarian tumors were significiantly higher than those in benign tumors(P0.05).Using VI≥0.035 counts/cm3 as a cutoff,the sensitivity and specificity in detecting malignant ovarian tumors were 84.2% and 70.0% respectively.VI and MVD in stage Ⅲ,Ⅳ were higher than that in stageⅠ,Ⅱ(P0.05).There was significant positive correlation between VI and MVD in 38 malignent ovarian tumors(r=0.684,P0.01).Conclusions TV3D-CPA can be used to evaluate the angiogenesis in ovarian tumors and provides valuable information to identify malignant ovarian tumors and tumor grade." @default.
