Abstract

Aim: To assess ultrasound (US) method informativeness in the recurrence detection and treatment monitoring of patients with cervical cancer metastases in the vagina via comparing the US and magnetic resonance imaging (MRI) data.

Materials and methods: 42 patients with recurrence of cervical cancer were examined by transvaginal US and MRI. Data on radiation diagnostics of cervical cancer metastasis in the vagina were compared with pathomorphological data. US and MRI data on the metastatic tumors size were compared.

Results: The diagnostic efficiency of US and MRI for recurrence detection was determined. The sensitivity, specificity and accuracy of US were 92.8; 93.3 and 93.3%, respectively, and of MRI - 95.2; 96.6 and 95.8%, respectively. The informativeness of MRI was higher than US in cervical cancer recurrences detection, but the difference was not significant (p > 0.05). US can provide data as informative as MRI for estimation of metastases sizes in the vagina. The mean difference between MRI measurements and US measurements of the metastases volume was 0.79 mm (95% CI 0.62-0.95 cm³).

Conclusions: US as a cheaper and simpler method could be an alternative for metastases detecting and treatment monitoring, especially if there are contraindications to MRI.

超声与MRI对宫颈癌阴道转移检测及治疗监测的信息量比较。

目的:通过超声(US)与磁共振成像(MRI)资料的比较，评价超声(US)方法在宫颈癌阴道转移患者复发检测及治疗监测中的信息价值。材料与方法:对42例宫颈癌复发患者行阴道超声及MRI检查。将宫颈癌阴道转移的放射诊断资料与病理形态学资料进行比较。比较US和MRI对转移瘤大小的影响。结果:确定了超声和MRI对复发的诊断效率。US的敏感性、特异性和准确性为92.8;分别为93.3和93.3%，MRI - 95.2;分别为96.6和95.8%。MRI检测宫颈癌复发的信息量高于US，但差异无统计学意义(p > 0.05)。超声造影可以提供与MRI一样的数据，用于估计阴道转移灶的大小。MRI测量和US测量的转移体积的平均差异为0.79 mm (95% CI 0.62-0.95 cm3)。结论:超声作为一种更便宜、更简单的方法，可以作为转移检测和治疗监测的替代方法，特别是在有MRI禁忌症的情况下。
