彩色多普勒在宫颈癌诊断及疗效评价中的应用进展

Application progress in diagnosis and assessment of therapeutic effect of cervical cancer by color Doppler ultrasound

宫颈癌是女性最常见的恶性肿瘤之一,临床上患者就诊时往往已处于晚期,预后不良。因此,早期诊断宫颈癌的发生并加以适当的干预可明显改善患者预后,延长生存时间。目前临床主要采用依据妇科检查及病理结果的国际妇产科联盟(FIGO)分期法判定患者所处状态,但不能准确判断宫旁、盆壁、直肠及膀胱侵犯、远处转移情况,准确性较差。近年来,彩色多普勒超声技术通过检测患者病变区及局部血流阻力指数(RI)变化可作为诊断宫颈癌范围及程度、放化疗效果评价的指标之一。另外,三维能量多普勒血管造影技术在早期宫颈癌的诊断中也起着重要的作用。现对彩色多普勒在宫颈癌诊断及疗效评价中的研究与应用做如下综述。

Cervical cancer is one of the most common malignant tumors of gynecology and obstetrics, patients are of- ten with advanced cancer for the first diagnosis, and prognosis is poor. Therefore, diagnosing early and giving proper interventions can significantly improve the prognosis and survival time of the patients. At present, the International Federation of Gynecology and Obstetrics （FIGO） staging method according to the gynecological examination and pa- thology results is the main staging method, it can judge the staging of patients, but can not judge the invasion of the palace, basin wall, rectum and bladder attack, distant metastasis accurately, accuracy is poor. In recent years, Color doppler ultrasound technology is one of the diagnostic index of diagnosing of cervical cancer and the degree, the scope and effect evaluation of radiation and chemotherapy through the detection of lesions area and local blood flow resist- ance index（RI） change of patients. In addition, three -dimensional power doppler angiography technology plays an important role in the diagnosis of early cervical cancer. This review will cover the research and application in diagnosis and assessment of therapeutic effect of cervical cancer by color doppler ultrasound.
