PDFAbstract
Objective To investigate the clinical value of endoscopic ultrasonography (EUS) combined with PET-CT in the diagnosis of preoperative T stage and N stage of esophageal cancer. Methods The imaging data of 72 patients with esophageal cancer who admitted to the hospital during the period from July 2016 to February 2018 were analyzed retrospectively. All patients underwent EUS and PET-CT before surgery, and pathological diagnosis was performed after surgery. With surgical and pathological results as the golden standard, and the diagnostic efficiency of EUS, PET-CT and both in the diagnosis of T stage and N stage of esophageal cancer were analyzed. Results The overall accuracy rates of EUS in the diagnosis of T stage and N stage of esophageal cancer were 75.00% and 80.56% while those of PET-CT were 79.16% and 88.88%. The overall accuracy rates of combined diagnosis for T stage and N stage of esophageal cancer were 95.83 % and 98.61%. The diagnostic accuracy was higher than that of EUS or PET-CT alone (P<0.05). Conclusion The diagnostic accuracy of EUS combined with PET-CT is good for preoperative T stage and N stage of esophageal cancer. The diagnostic efficiency is better than EUS or PET-CT alone.
