贲门癌MDCTT分期与病理对照

目的评价MDCT对贲门癌T分期的意义。方法参照AJCC 2010胃癌分期标准,对65例贲门癌患者通过术前MDCT影像行T分期,对CT显示不同层状结构病例,分别分析CT T分期与病理T分期的差异、病变胃壁厚度与T分期的相关性;以手术病理分期为金标准,计算MDCT对贲门癌T分期诊断的敏感度与准确率。结果 CT显示胃壁三层结构32例(32/65,49.23%),二层结构19例(19/65,29.23%),未显示分层14例(14/65,21.54%)。CT显示三层结构、二层结构及未显示分层者的T分期准确率分别为87.50%(28/32),73.68%(14/19),78.57%(11/14)。贲门癌病变胃壁厚8～41mm,平均23.4mm,以20mm为阈值,厚度≥20mm的病变86.67%(39/45)侵犯浆膜。结论 CT显示胃壁层次不同可用于贲门癌的分期诊断;MDCT对贲门癌的术前T分期与病理结果的一致性较好。

T staging of cardiac carcinoma on MDCT : Comparison with pathology

Objective To investigate the value of MDCT in T stage of cardiac carcinoma.Methods Refer to AJCC 2010 staging of gastric cancer,preoperative T staging of 65 cases of cardiac carcinoma confirmed pathologically was performed using MDCT,and the results were compared with pathological T staging.The sensitivity and accuracy of MDCT in T staging of cardiac carcinoma were calculated.Results Three-layer structure of gastric wall was showed on CT in 32 cases(32/65,49.23%),2-layer structure in 19(19/65,29.23%) and one layer structure in 14 cases(14/65,21.54%),and the corresponding diagnostic accuracy of T staging with pathological diagnosis was 87.50%(28/32),73.68%(14/19) and 78.57%(11/14),respectively.The average thickness of stomach wall of cardiac carcinomas was 23.4 mm(8—41 mm).Taking 20 mm as the threshold,86.67%(39/45) cases with gastric thickness ≥20 mm had serosal invasion.Conclusion Different parietal layers of gastric wall on MDCT imaging can be used in different diagnosis T staging of cardiac carcinoma.MDCT has in good agreement with pathological T staging of cardiac carcinoma.
