The comparison between clinical and MRI staging with the final stage was performed on 74 patients with invasive carcinoma of the uterine cervix who were visited and diagnesel from Jan. 1990 through Apr. 1994. 41 patients among these patients
subsequently recevied radical abdominal hysterectomy and bilateral pelvic lymph node dissection.
@ES The results were as follows:
@EN 1. The overall accuracy of clinical stage and MR imaging in staging carcinoma of the cervix, compared with final stage including histopathological results, were 70%(52/74) and 55%(41/74), respectively.
2. By clinical and MRI evaluation, the accuracies were 82.9% and 70% respectively for the detection of vaginal extension, 100% and 87.8% respectively for the detection of cervical involvement, and both 100% for the detection of rectal, bladder,
and
urinary tract involvement.
3. In detecting parametrial involvement, clinical and MRI finding had an accuracy of 68.3% and 65.9%, respectively.
4. The sensitivity and specificity for MRI for the detection of parametrial involvement were 33.3% and 68.4%, respectively and its positive and negative predictive value were 7.7% and 92.9%.
5. The presence of absence of lymph node metastasis can not be detected by clinical eramination alone but, accuracy was 75.6% for the detection of lymph node metastasis by MRI evaluation.
We concluded that the clinical staging was superior to MRI staging as a whole when they were compared by final staging and the clinical evaluation for the detection of vaginal extension and cervical involvement was superior to MRI evaluation, but
both
methods have simillar accuracies for the detection of the parametrical involvement and MRI evaluation was superior to clinical evaluation for the detection of lymph node involvement.
