Fifty-nine patients with primary or recurrent carcinoma of the cervix were evaluated by computed tomography as part of their presurgical evaluation. The computed tomography staging results were compared with the surgical staging. Computed tomography staging was accurate in 71% (42 of 59), whereas clinical staging was accurate in 66% (39 of 59). In assessing paraaortic nodes by CT, there were 10 true-positive, 20 true-negative, 1 false-positive, and 2 false-negative results (sensitivity, 83%; specificity, 95%), for an overall accuracy of 91%. For pelvic nodes, there were 10 true-positive, 11 true-negative, 3 false-positive, and 6 false-negative results (sensitivity, 62.5% specificity, 78%), for an overall accuracy of 70%. Excretory urograms and barium enemas provided no information not obtained by computed tomography and are probably unnecessary if computed tomography is used as a routine staging examination. At present, computed tomography should not replace clinical assessment of extent of the disease. Its chief advantage over clinical staging is its ability to detect metastases beyond the true pelvis.
59例原发性或复发性宫颈癌患者在术前评估时接受了计算机断层扫描（CT）检查。将CT分期结果与手术分期进行比较。CT分期的准确率为71%（59例中的42例），而临床分期的准确率为66%（59例中的39例）。在通过CT评估腹主动脉旁淋巴结时，真阳性结果10例，真阴性结果20例，假阳性结果1例，假阴性结果2例（敏感性83%；特异性95%），总体准确率为91%。对于盆腔淋巴结，真阳性结果10例，真阴性结果11例，假阳性结果3例，假阴性结果6例（敏感性62.5%，特异性78%），总体准确率为70%。排泄性尿路造影和钡剂灌肠未提供CT未获得的信息，如果将CT用作常规分期检查，可能是不必要的。目前，CT不应取代对疾病范围的临床评估。它相对于临床分期的主要优势在于能够检测真骨盆以外的转移灶。
