Missing rate for gastric cancer during upper gastrointestinal endoscopy: a systematic review and meta-analysis (Pimenta-Melo AR. Eur J Gastroenterol Hepatol 2016)¶ó´Â Èï¹Ì·Î¿î ³í¹®µµ ¼Ò°³ÇØ Áּ̽À´Ï´Ù.

RESULTS; The studies included (n=22) were grouped by study design. The pooled negative predictive value was 99.7% (95% confidence interval 99.6-99.9%). Missed GCs proportion was 9.4% (95% confidence interval 5.7-13.1%), being 10.0% in studies including patients with negative EGD followed over time, 8.3% in studies including patients with GC, and 23.3% in studies evaluating the proportion of missed synchronous lesions. Mainly, missed cancers were located in the gastric body both in Eastern and in Western studies (39 and 47%, respectively). The majority of missed GCs were adenocarcinomas. Younger age (<55 years), female sex, marked gastric atrophy, gastric adenoma or ulcer, and inadequate number of biopsy fragments were reported as predictive factors for diagnostic failure.
