DIAGNOSTIC ACCURACY IN RESECABLE ESOPHAGEAL CANCER

Abstract INTRODUCTION In localized oesophageal cancer (EC), a correct clinical tumor staging is essential in order to offer an optimal treatment, although often challenging. The aim of this work assess the accuracy diagnostic tests by comparing them with pathological staging. MATERIAL AND METHODS Retrospective observational study patients who underwent oesophagectomy for referral hospital between January 2003 and September 2019. Those received neoadjuvant treatment were excluded avoid bias from dowstaging effects. preoperative stage cT cN as well combination both (cTNM) compared surgical specimen (pT, pN, pTNM), considered gold standard. Computed tomography (CT) endoscopic ultrasound (EUS) evaluated cN, while Positron emission (PET/CT) only cN. Furthermore, pT was correlated length described oesophagogram (EG). RESULTS Among 63 included, 16 cases (global 25.4%), it overstaged 21 (33.2%) understaged 26 (41.3%). For staging, EUS higher than that CT (46.6% 34.9% respectively), specially early stages. EG (p < 0.05). PET/CT had highest sensitivity (50.0%) NPV (75.0%). CONCLUSIONS Despite multiple tools used, global EC still challenge, therapeutic prognostic implications entails.
