摘要
目的 探讨MRI及CT检查技术在儿童肾母细胞瘤(WT)国际儿童肿瘤协会(SIOP)分期中价值.方法 回顾性分析2020 年1 月至2022 年12 月于安徽省儿童医院经病理证实的WT 32 例,分析影像特点,并对其实行SIOP分期,比较MRI与CT成像分期差异性.结果 MRI及CT检查在SIOP 分期Ⅰ期准确率分别为 81.25%、71.88%(P>0.05),Ⅱ期准确率分别为 78.12%、59.38%(P>0.05),Ⅲ期准确率分别为 96.88%、87.50%(P>0.05),Ⅳ期及Ⅴ期准确率均为100%(P>0.05),总分期准确率分别为 91.25%、83.75%(P<0.05),其中MRI及CT检查在 SIOP Ⅰ～Ⅴ期分期准确率上无统计学差异,而总分期准确率差异具有统计学意义.结论 MRI及CT检查对儿童WT SIOP 分期均有较高的准确率,尤其是MRI在总分期准确率上具有更好的分期价值,可提供更多的影像参考信息.
Abstract
Objective To investigate the value of MRI and CT in SIOP staging of Wilms tumor(WT)in children.Methods Thirty-two WT cases confirmed pathologically in Anhui Children's Hospital from January 2020 to December 2022 were analyzed retrospectively.The imaging characteristics were analyzed,and SIOP staging was performed on all WT ca-ses,and the differences between MRI and CT imaging staging were compared.Results The accuracy rates of MRI and CT were 81.25% and 71.88% (P>0.05)in SIOP stageⅠ,78.12% and 59.38% (P>0.05)in stageⅡ,96.88% and 87.50% (P>0.05)in stage Ⅲ,respectively.The accuracy of stage Ⅳ and Ⅴ was 100% (P>0.05),and the total staging accuracy was 91.25% and 83.75% (P<0.05),respectively.There was no statistical difference between MRI and CT in the staging accuracy of stageⅠ-Ⅴ of SIOP,while the difference in the total staging accuracy was statistically sig-nificant.Conclusion Both MRI and CT have high accuracy in WT SIOP staging of children.In particular,MRI has bet-ter staging value in the overall staging accuracy and can provide more image reference information.
