摘要
目的:探讨经阴道三维彩色血管能量成像(TV3D-CPA)对卵巢肿瘤的诊断价值及其与恶性肿瘤临床分期的关系。方法:术前应用TV3D-CPA技术检测65例卵巢肿瘤(47例恶性肿瘤,18例良性肿瘤),定量计算肿瘤内血管指数(VI),分析VI值在良、恶性肿瘤中的差异性及其与恶性肿瘤临床分期的关系。结果:卵巢恶性肿瘤VI值(0.080±0.052)条/cm3,明显高于良性组(0.043±0.031)条/cm3(P<0.05)。以VI≥0.035条/cm3诊断卵巢恶性肿瘤敏感性87.8%,特异性75%。Ⅲ、Ⅳ期卵巢恶性肿瘤VI值(0.089±0.037)条/cm3,明显高于Ⅰ、Ⅱ期(0.056±0.04)条/cm3(P<0.05)。结论:应用TV3D-CPA计测VI值是鉴别卵巢良、恶性肿瘤的有效方法。VI值随临床分期的增高而升高,是预后评价的重要指标。
Abstract
Objective: To explore the value of transvaginal three-dimensional color power angiography(TV3D-CPA) in the diagnosis of ovarian tumors and determine the relationship between TV3D-CPA and clinical stages of malignant ovarian tumors. Methods: Sixty-five ovarian tumors(47 malignant ovarian tumors, 18 benign ovarian tumors) were examined with TV3D-CPA preoperatively, and the vascular index(VI) of tumors were determined. The difference in VI between benign and malignant ovarian tumors were analysed, and the relationship between VI and clinical stages were evaluated. Results: The VI of 47 malignant ovarian tumors with (0.08±0.052)counts/cm3 was higher than that of benign tumors with (0.043±0.031)counts/cm3(P<0.05). Using the VI≥0.035counts/cm3 as the cutoff, its sensitivity and specificity in detecting malignant ovarian tumors were 87.8% and 75%, respectively. VI in stage Ⅲ and Ⅳ (0.089±0.037)counts/cm3 was higher than that in stageⅠand Ⅱ (0.056±0.04)counts/cm3(P<0.05). Conclusion: TV3D-CPA was an effective method to indentify benign and malignant ovarian tumors by calculating VI. The higher the clinical stage was, the higher the VI will be, which might be an important index for predicting prognosis.
