BACKGROUND/AIMS: To assess the accuracy and limitation of endoscopic ultrasonography in preoperative staging of gastric cancer, we performed a prospective study on 99 patients.
MATERIAL AND METHODS
Ninety-nine patients with gastric cancer had preoperative staging with endoscopic ultrasound (EUS) and CT.
RESULTS
The depth of infiltration (T parameter) was correctly defined by EUS in 58/65 patients (89%). The lymph node involvement (N parameter) was correctly classified in 44/65 patients (68%), the sensitivity was 74% and the specificity was 54%. The most frequent cause of understaging T parameter was microscopic tumor invasion, whereas overstaging was due to peri-tumor inflammation.
CONCLUSIONS
We believe that EUS is a reliable method, superior to all diagnostic tools, in the evaluation of locoregional extension of gastric cancer.
背景/目的：为评估内镜超声检查在胃癌术前分期中的准确性和局限性，我们对99例患者进行了一项前瞻性研究。
材料与方法
99例胃癌患者术前行内镜超声（EUS）和CT分期。
结果
EUS正确界定了65例患者中58例（89%）的浸润深度（T参数）。65例患者中44例（68%）的淋巴结受累情况（N参数）被正确分类，敏感性为74%，特异性为54%。T参数分期过低的最常见原因是微小肿瘤浸润，而分期过高则是由于肿瘤周围炎症。
结论
我们认为，在评估胃癌局部区域扩展方面，EUS是一种可靠的方法，优于所有诊断工具。
