Prospective Evaluation of Positron Emission Tomography in the Preoperative Staging of Esophageal Carcinoma

摘要: Hypothesis Positron emission tomography (PET) is a useful tool in the selection of patients with esophageal cancer who may not benefit from resection. Design Case series. Setting Tertiary care hospital. Patients Eighty-one newly diagnosed underwent PET and computer (CT) chest abdomen (and neck 45 patients) within days were included. Main Outcome Measures We calculated sensitivity specificity detecting metastatic sites on basis 31 histologically verified lesions. In addition to results obtained CT, information provided by was evaluated view choice management strategies. Results The findings had higher (89% vs 11%) but lower (38% 63%) than CT detection sites. showed greater agreement histopathological did results. 8 (10%), detected distant metastases that identified CT. 4 (5%), bone only, all these other locations Although led upstaging (M1) 2 (2%), it enable exclusion Conclusions Preoperative characterized accuracy previously Therefore, lead change indication for esophagectomy. An increase combined use new indications this staging procedure.
