CIMAVILLA-ROMAN, Marta et al. Endoscopic ultrasound versus multidetector computed tomography in preoperative gastric cancer staging. Rev. esp. enferm. dig. [online]. 2017, vol.109, n.11, pp.761-767. ISSN 1130-0108.  https://dx.doi.org/10.17235/reed.2017.4638/2016.

Introduction: Endoscopic ultrasonography (EUS) is the gold standard technique in loco-regional staging of gastric adenocarcinoma (GAC). Nevertheless, the introduction of multidetector-row computed tomography (MDCT) allows accurate studies to be performed. Objective: To compare the diagnostic yield of EUS and MDCT in loco-regional preoperative staging of gastric adenocarcinoma. Material and methods: This was a retrospective and comparative study of all surgical patients with GAC and preoperative staging by EUS and 64-row MDCT. The results for each case were compared with the histological data. Results: Seventy seven surgical patients with GAC were identified and forty two had a complete preoperative staging and were finally included in the study. With regard to overall accuracy of T staging, EUS was superior to MDCT (62% vs 50%). In a subanalysis of early stages (T1-T2) and advanced stages (T3-T4), accuracy and sensitivity (S) were higher for EUS than for MDTC (83.3% vs 64.29% and 84.4% vs 59.5% respectively), although this did not reach statistical significance. The overall accuracy and sensitivity of EUS for N staging was lower than that for MDCT, although neither comparison reached statistical significance (57% vs 64% and 29% vs 55%). Conclusions: EUS diagnostic yield is similar to new MDCT with regard to T and N preoperative staging of GAC. Nevertheless, both techniques should be considered as complementary until more extensive and randomized studies can confirm these results.
