目的探讨CT和磁共振成象(MRI)检查对食管癌术前原发肿瘤分期和区域性淋巴结转移的评判价值。方法选取2009年至2012年间收治的术后经病理确诊的食管癌患者91例,其中行CT检查者53例(CT组),行MRI检查者38例(MRI组),回顾性分析两组患者术前影像学检查对食管癌术前原发肿瘤分期和有无区域性淋巴结转移的评判,并与术后病理结果进行对照。结果 CT组患者的食管癌术前原发肿瘤分期(T分期)的诊断准确率为83.0%,MRI组患者的食管癌术前原发肿瘤分期(T分期)的诊断准确率为79.0%,差异无统计学意义(P>0.05);在纵隔淋巴结转移(N分期)和腹部淋巴结转移上CT组的灵敏度、特异度、准确度分别为81.5%、76.9%、79.3%和78.6%、80.0%、79.3%,而MRI组的灵敏度、特异度、准确度分别为84.2%、79.0%、81.6%和85.0%、83.3、84.2%,两组间差异无统计学意义(P>0.05)。结论 CT和MRI检查对食管癌术前原发肿瘤分期和区域性淋巴结转移评判效果相当,但CT价格较低,操作较简单,值得临床推广。
Objective To investigate the diagnostic value of CT and magnetic resonance imaging (MRI) in staging and regional lymph node metastasis of preoperative primary tumor of esophageal cancer. Methods Totally 91 patients with pathologically confirmed esophageal cancer who were admitted to our hospital from 2009 to 2012 were enrolled. Among them, 53 patients underwent CT (CT) and 38 underwent MRI (MRI). Retrospective analysis of two groups of patients Preoperative imaging examination of esophageal cancer preoperative primary tumor staging and regional lymph node metastasis evaluation, and postoperative pathological results were compared. Results The diagnostic accuracy rate of preoperative primary tumor staging (T stage) of esophageal cancer was 83.0% in CT group, 79.0% of preoperative T stage in esophageal cancer patients in MRI group, the difference was statistically significant The sensitivity, specificity and accuracy of the CT group were 81.5%, 76.9%, 79.3% and 78.6%, 80.0% respectively in the mediastinal lymph node metastasis (N staging) and abdominal lymph node metastasis (P> 0.05) 79.3%, while the sensitivity, specificity and accuracy of the MRI group were 84.2%, 79.0%, 81.6% and 85.0%, 83.3 and 84.2% respectively. There was no significant difference between the two groups (P> 0.05). Conclusions CT and MRI are effective in assessing the preoperative staging and regional lymph node metastasis of esophageal cancer, but the CT price is lower and the operation is simpler, which is worthy of clinical promotion.
