MRI在原发性输卵管癌临床分期中的应用价值

The explore of MRI for staging primary fallopian tube carcinoma

目的探讨MRI在原发性输卵管癌临床分期中的应用价值。方法回顾性分析9例经手术病理证实的输卵管癌患者的MRI资料,将肿瘤的定位、局部浸润、淋巴结转移、腹膜转移及远处转移等影像学表现,与手术所见、病理结果及临床分期相结合进行分析。结果本组9例均为单侧(左6例/右3例),腹盆腔积液5例,仅盆腔积液1例,子宫/卵巢受累7例,盆腔其它脏器受累6例,盆腔外腹膜种植转移5例,淋巴结阳性3例,远处转移1例。影像学分期IA期2例,IIA期1例,IIB期1例,IIIC期5例。淋巴结阳性诊断正确率75%,其余上述影像学表现及分期的诊断符合率均为100%。结论 MRI增强检查对原发性输卵管癌周围结构的侵犯及远处转移情况,均能清楚、准确显示,从而指导临床制定适合患者的手术方案。

Objective To conclusion the value of MRI for staging primary fallopian tube carcinoma. Methods The MRI data of 9 patients with pathologically proved primary fallopian tube carcinoma were analyzed retrospectively. The location of tumor, local invasion or other pelvic tissues, peritoneum metastasis, lymph node metastasis and distal metastasis were recorded. The results were compared with operative and pathological findings. Results In this group, 9 cases were unilateral （ left/right 6 cases 3 cases）, in 5 eases of abdominal and pelvic effusion, only 1 case of pelvic fluid, uterus/ovary was involved in 7 cases, 6 cases of other pelvic organ involvement, pelvic peritoneal metastasis 5 cases, positive lymph nodes in 3 eases, distal metastasis in 1 case. There were 2 cases of stage IA, 1 case of stage IIA, 1 case of stage IIB, and 5 cases of stage IIIC. The positive rate of lymph node positive diagnosis was 75%, and the coincidence rate of the other imaging manifestations and staging was about 100%. Conclusion MRI enhanced examination of the primary fallopian tube carcinoma around the structure of the invasion and distant metastasis, can be clearly and accurately displayed, so as to guide the clinical development of suitable surgical procedures for patients.
