子宫颈癌经细胞学检查确诊,并确切地估计其扩散范围而选择治疗方法。根治性切除术是选择Ⅰ～ⅡB期的病例,而放射治疗则选择ⅡB～ⅠVB期的病例。因此,准确的分期至为重要。与手术分期相对照,临床分期的误差率为24～39%。误差的最常见原因是未能发现宫旁肿瘤扩散或盆腔和主动脉旁淋巴转移。为了提高宫颈癌术前分期诊断的准确率,近10年来增加了CT影像学评价。但CT对临床ⅠB～ⅡA期肿瘤不是常规。因为有经验的妇科肿瘤学家对ⅠB～ⅡA检查的准确率较CT高得
Cervical cancer confirmed by cytology, and to accurately estimate the extent of its proliferation and choose the treatment. Radical resection is the choice of Ⅰ ~ Ⅱ B cases, while radiotherapy is to choose Ⅱ B ~ Ⅰ VB cases. Therefore, accurate staging is of paramount importance. Compared with the surgical staging, the clinical staging error rate of 24 to 39%. The most common cause of error was the failure to find paracarcinoma or pelvic and para-aortic lymphoid metastases. In order to improve the accuracy of preoperative staging of cervical cancer, CT imaging evaluation has been added in the past 10 years. However, CT is not routine for stage IB-IIA tumors. Because of the experience of gynecologic oncologists ⅠB ~ Ⅱ A check the accuracy rate is higher than CT
