Core Tip
Core tip: In low-risk countries, most gastric cancers are diagnosed at an advanced stage without possibility for curative treatment. There is a need for better selection of patients with precancerous findings for surveillance. Operative link for gastritis assessment (OLGA) and operative link on gastric intestinal metaplasia assessment (OLGIM) staging systems provide a useful tool to evaluate the gastric cancer risk. We have developed a novel staging, TAIM, which combines atrophy and intestinal metaplasia. Our results support the earlier findings that OLGIM detects high-risk patients better than OLGA, and with TAIM staging, even more patients could be detected and forwarded for beneficial endoscopic surveillance.
