摘要 目的:探讨CT、MRI及经直肠超声(transrectal ultrasonography,TRUS)在直肠癌术前T分期中的应用价值。方法:收集本科2013年1月至2014年1月收治的直肠癌患者临床资料,统计CT、MRI及TRUS 3种检查术前T分期与术后病理分期完全符合的准确率。根据临床需要,进而将病理分期为T1和T2期的患者术前检查分期为T1或T2,病理分期为T3和T4期的患者术前检查分期为T3或T4均认定是准确的,定义为基本符合,统计3种检查基本符合的准确率。对3种检查完全和基本符合的准确率进行比较。结果:CT对T4期诊断的完全符合准确率为58.62%,与MRI及TRUS无明显差异;MRI术前T分期完全、基本符合的准确率为61.21%、79.39%,对T3~4期的准确率高于T1~2期;TRUS术前T分期完全、基本符合的准确率为64.06%、92.19%,对T3~4期基本符合的准确率高于T1~2期;TRUS基本符合的准确率显著高于MRI;MRI及TRUS对T1期诊断完全符合的比例均较低。结论:MRI及TRUS在确定患者是否需要新辅助放疗时均有较高的应用价值,3种检查均不能提供可靠的T分期诊断来确定是否可行局部切除术。
