A total of 162 patients with invasive cervical cancer was investigated retrospectively with a view to elucidate the efficacy of pretreatment staging procedures of application with intravenous pyelography, cystoscopy, rectosigmoidoscopy. All 72 intravenous pyelograms, 155 sigmoidoscopies, 158 cystoscopies were normal. Of 111 patients with stage Ib who had paraaortic lymph node biopsies, two patients had a positive node(0.02%). Of 51 patients with stage II who had paraaortic lymph node biopsies, five patients had positive paraaortic lymph node(10%). And the accuracy of computed tomography and magnetic resonance imaging in the evaluation of invasive cervical cancer was assessed. In evaluating stage of cervical cancer, clinical staging had an accuracy of 78.9%, compared with 65.7% for CT and 58.9% for MRI. And for detection of parametrial invasion, clincal staging had an accuracy of 85.9%, compared with 85.1% for CT and 78.9% for MRI. Both modalities were comparable in evaluating lymph node metastasis ( 76.1% for CT, 74.4% for MRI ). IVP, cystoscopy and sigmoidoscopy for staging procedure evaluated in this study are unnecessary and should no longer be performed in patients with early stage cervical cancer. In addition, paraaortic lymph node biopsies in the absence of clinically suspicious nodes are not warranted. Compared with CT and MRI, pelvic examination offered improved evaluation of cervical cancer staging, parametrial invasion, but CT and MRI was useful in detecting the pelvic lymph node metastasis which was nearly impossible by clinical evaluation.
