摘要
Background New or missed gastric cancer rates after negative endoscopy are high. However, the clinicopathologic characteristics of missed or interval early gastric cancer (EGC) are not well known. The aim of this study was to evaluate clinicopathologic and endoscopic characteristics of missed or interval EGC after negative endoscopy. Methods We retrospectively analyzed 1,055 patients with EGC confirmed by endoscopic resection or surgery between June 2006 and July 2013. Referred patients with diagnosed or suspected gastric neoplasms were excluded (n = 771). Interval EGC was defined as gastric cancer diagnosed within 2 years of negative endoscopy. Clinicopathologic characteristics of patients with initially detected and interval EGC and risk factors for interval EGC were investigated. Results Of 284 patients, 52 had interval EGC (18.3 %; mean age 65.4 years; average interval between diagnosis and previous endoscopy, 12.6 months). Tumors were significantly smaller (1.3 vs. 1.8 cm, P < 0.001), and the incidence of metaplasia was significantly higher (90.4 vs. 65.9 %, P < 0.001) for interval EGC than for initially detected EGC. And no symptoms (50 vs. 17.7 %, P < 0.001) were significantly associated with interval EGC. However, tumor location, differentiation, gross morphology, and Helicobacter pylori infection status did not differ significantly. Conclusions Subtle mucosal lesions with surrounding intestinal metaplasia were associated with interval EGC. Careful endoscopic screening for patients with intestinal metaplasia at short-term interval would be beneficial for decreasing interval EGC rates.
