The present study was designed to compare the value of MRI, CT and clinical examination in local tumor staging of gynaecologic malignancies.
99 patients with clinically suspected carcinoma of the cervix uteri, ovarian carcinoma or tumor recurrence after gynaecologic cancer underwent all three staging modalities. Furthermore CT and MRI were compared in detecting lymph node metastasis and peritoneal implants.
MRI was superior to CT and clinical staging in local tumor staging with an accuracy of 77% for cervical carcinoma and of 88% for recurrent tumors, whereas CT achieved an accuracy of 65% and 55% and clinical staging 60% and 63% accuracy for carcinoma of the cervix and recurrent cancer. Especially for local staging of these two tumor entities MRI is very useful. MRI and CT reached comparable results in the detection of ovarian tumors with an accuracy of 73% for MRI and 69% for CI. Both imaging modalities also showed equal results in the detection of lymph node metastasis, so that primary the cost saving use of CT tumor staging for ovarian lesions and lymph node metastasis should be favoured.
本研究旨在比较MRI、CT及临床检查在妇科恶性肿瘤局部肿瘤分期中的价值。
99例临床怀疑子宫颈癌、卵巢癌或妇科癌症术后肿瘤复发的患者接受了上述三种分期检查方法。此外，还对CT和MRI在检测淋巴结转移及腹膜种植方面进行了比较。
在局部肿瘤分期方面，MRI优于CT及临床分期，子宫颈癌的准确率为77%，复发性肿瘤的准确率为88%；而CT对子宫颈癌及复发性癌的准确率分别为65%和55%，临床分期的准确率分别为60%和63%。尤其是对于这两种肿瘤实体的局部分期，MRI非常有用。在检测卵巢肿瘤方面，MRI和CT的结果相当，MRI的准确率为73%，CT为69%。两种成像方式在检测淋巴结转移方面也显示出相同的结果，因此，就成本效益而言，对于卵巢病变及淋巴结转移，应优先使用CT进行肿瘤分期。
