The rates of missed gastric cancers (MGC) at upper endoscopy (UE) has been reported at 5-10% in Western countries. We aimed to calculate the rate of MGC and identify factors associated with MGC.
Retrospective population-based cohort study including 730 patients diagnosed with gastric adenocarcinoma in Central Norway 2007-2016. MGCs were incident gastric adenocarcinomas diagnosed 6-36 months after a previous UE. Factors associated with MGC were examined. Definitely missed (UE 6-12 months prior) and potentially missed (UE 12-36 months prior) MGCs were compared.
Sixty-seven (9.2%) of 730 gastric cancers were MGC. MGC were associated with localization ( = 0.009) and more frequent in the corpus, Lauren's histological type ( = 0.028) and diffuse type more prevalent, and previous Billroth 2-operation (14.9% vs. 4.7%, = 0.001). MGCs were diagnosed at earlier stages ( = 0.037). An ulceration was more common in patients with definitely missed than potentially MGC (40.9% vs. 17.8%, = 0.041).
MGC accounted for 9.2% of gastric cancers in Central Norway. MGC were associated with localization in the corpus, Lauren´s diffuse type and previous Billroth-2-operation. Intensified follow-up and adequate biopsy sampling of patients with gastric ulcerations could reduce the rate of missed gastric cancers.
西方国家报道上消化道内镜检查（UE）时胃癌漏诊率为5%-10%。我们旨在计算胃癌漏诊率并确定与胃癌漏诊相关的因素。
基于人群的回顾性队列研究，纳入2007年至2016年在挪威中部诊断为胃腺癌的730例患者。胃癌漏诊是指在前次UE检查后6至36个月确诊的新发胃腺癌。研究了与胃癌漏诊相关的因素。比较了明确漏诊（前次UE检查6至12个月前）和可能漏诊（前次UE检查12至36个月前）的胃癌。
730例胃癌中有67例（9.2%）为漏诊病例。胃癌漏诊与病变部位有关（P = 0.009），胃体部更为常见，Lauren组织学类型有关（P = 0.028），弥漫型更为普遍，以及既往毕Ⅱ式手术（14.9%对4.7%，P = 0.001）。漏诊的胃癌诊断时分期较早（P = 0.037）。明确漏诊的患者比可能漏诊的患者溃疡更为常见（40.9%对17.8%，P = 0.041）。
在挪威中部，胃癌漏诊占胃癌的9.2%。胃癌漏诊与胃体部病变、Lauren弥漫型以及既往毕Ⅱ式手术有关。加强对胃溃疡患者的随访和充分的活检取样可降低胃癌漏诊率。
