经内镜和病理证实并接受手术治疗的182例食管癌患者入组,患者均在术前1周接受多层螺旋CT( MSCT)和氟代脱氧葡萄糖正电子发射断层扫描CT(18F-FDG PET-CT)扫描,结合图像信息,记录其术前分期,并与术后病理结果比较。 MSCT与18 F-FDG PET-CT扫描对判断T分期准确率的差异无统计学意义(字2=0.540,P=0.463),而18F-FDG PET-CT扫描对判断 N 分期的灵敏度、特异度及准确率均高于MSCT(P<0.05)；术前MSCT扫描检测T、N分期与术后病理一致性差(Kappa=0.376,Kappa=0.317,P<0.01),而术前18 F-FDG PET-CT 扫描检测 N 分期与术后病理高度一致(Kappa=0.750,P<0.01)。

The clinical data obtained from 182 cases with esophageal cancer proved by pathology endoscopy were retrospectively analyzed, which were treated with surgery. Multi-slice computer tomography( MSCT) and 18 F-FDG positron emission tomograp-hy combined computed tomography(18 F-FDG PET-CT) scans were underwent for the patients within one week before treatment;combined with the images to record the preoperative MSCT and 18 F-FDG PET-CT staging,TNM staging of the patients with operation was compared with post-operative pathological results based on various imaging findings. In comparison to post-operative pathological results,the difference between accu-racy of T staging diagnosed by MSCT and PET-CT was no significance (P<0.05),but the sensitivity,specificity and accuracy of regional lymph node metastases diagnosed by PET-CT had an advantage over that by MSCT ( P<0.05). The Kappa values for MSCT scans in T and N staging diagnosis were not ideal(Kappa<0.40,P<0.01), but it was favorable for preoperative PET-CT scans in N staging diagnosis(Kappa>0. 40,P<0.01).
