The authors evaluate the efficacy of preoperative endoscopic ultrasonography (EUS) in assessing site, depth of tumor infiltration and regional lymph node metastasis, as compared to pathologic and endoscopic data available, in 43 patients affected by gastric cancer, observed during the period 1987-1990. The overall accuracy in the assessment of the extent of tumor infiltration was 76%; in particular, it was 100% for EGC (T1), 64% for T2, 85% for T3 and 64% for T4. The overall accuracy in the assessment of regional lymph node metastasis was 77.1%. No significative difference was registered in assessing the site of tumor, as compared to simply endoscopy. Ecoendoscopy seems fundamental in preoperative assessment of early gastric cancer; moreover, it is essential in assessing the depth of tumor infiltration of gastric cancer, being less significant its role in staging lymph node metastasis.
