The results of our study highlight the need for change in the pretreatment workup of clinical stage Ib cervical cancer. The routine use of excretory urography, barium enema, cystoscopy,and sigmoidoscopy is not justified. MR evaluation is recommended in patients with lesions larger than 2 cm (the group with the greatest increase in predictive value). Although CT scanning is not recommended for the evaluation of parametrial invasion, both CT scanning and MR imaging provide similar positive and negative posttest probabilities for the evaluation of nodal disease.
我们的研究结果凸显了临床Ib期宫颈癌术前检查工作需要改变。排泄性尿路造影、钡灌肠、膀胱镜检查和乙状结肠镜检查的常规使用并不合理。对于病灶大于2cm的患者（预测价值增加最大的组），建议进行磁共振评估。虽然不推荐使用CT扫描评估宫旁浸润，但CT扫描和磁共振成像在评估淋巴结疾病时提供的检验后阳性和阴性概率相似。
