超声多因素诊断前列腺癌的前瞻性研究

Prospective study on diagnosis of prostatic cancer with the ultrasonic multifactor

目的 探讨超声多因素诊断前列腺癌的价值。方法 应用超声观测前列腺癌组、前列腺增生组及对照组前列腺外腺连续性、左右侧半前列腺体积差及前列腺血流参数Vs、RI等多因素。结果 超声多因素诊断前列腺癌符合率 90 .91%、敏感性 76 .92 %、特异性 97.37%。结论 外腺连续性部分甚至完全中断 ,左右侧半前列腺体积差大于 3.0cm3 ;Vs>2 5cm/s;RI<0 .6 0符合上述条件 2项或 2项以上者可诊断为前列腺癌。

Objective To evaluate the prognostic value of ultrasonic multifactor on prostatic cancer.Methods Using ultrasound, the continuity of outside gland of prostate gland,the balance between left and right semi-prostate gland volume (V),and the blood flow parameter:(Vs,RI) were measured in three groups:the prostatic cancer group,the prostatauxe group and the normal control group.Results The coincidence rate of diagnosis with ultrasonic multifactor was 90.91%,the susceptibility was 76.92%,the specificity was 97.37%.Conclusion When 2 or more than 2 of the following conditions are present continuity of outside gland of prostate gland being broken off,the V>3.0cm 3,the Vs>25cm/s,and the RI<0.60,it can be diagnosed as prostatic cancer.
