18F-氟脱氧葡萄糖PET、超声内镜及CT在食管癌术前分期中的应用

18F-fluorodeoxyglucose PET, endoscopic ultrasound and CT in the initial staging of patients with esophageal cancer

  • 摘要: 食管癌术前准确分期对治疗方案的选择及预后判断有重要意义。目前,食管癌分期方法主要有18F-氟脱氧葡萄糖(18F-FDG)PET、超声内镜及CT.超声内镜对食管癌T分期价值较高,三种方法对食管癌局部淋巴结的分期(N分期)各有优缺点,18F-FDG PET对远处转移灶(M分期)的发现有明显的优势.综合运用18F-FDG PET、超声内镜及CT可明显提高食管癌术前分期的准确性。

     

    Abstract: Accurate staging of esophageal cancer is important because optimal management and survival closely correlates with tumor, nodal and metastatic (TNM)stage. 18F-FDG PET, endoscopic ultrasound (EUS) and CT are performed in staging of newly diagnosed patients with esophageal cancer.Endoscopic ultrasound has superior T staging ability over PET and CT.18F-FDG PET, endoscopic ultrasound and CT have diffient vaiue for assessment nodal metastases. PET is especially useful when there is suspicion of distant metastases. There will improve the overall accuracy in staging of patients with esophageal cancer by 18F-FDGPET,EUS and CT.
