| Outline of Final Research Achievements |
Helicobacter pylori infection and the degree of chronic atrophic gastritis are significant predictors for the development of gastric cancer, especially in the Japanese population. A combination of assays for serum anti-Helicobacter pylori immunoglobulin G antibody (HPA) and serum pepsinogen (PG) levels can be used to identify gastric cancer risk. In Japan, this ABC method may be an effective approach for identifying high-risk individuals who should undergo gastric cancer screening. The present study’s purpose was to estimate the long-term cost-effectiveness of the ABC method for assessing the gastric cancer risk in a Japanese population. We constructed a Markov cohort model to estimate the cost-effectiveness of ABC method. We suggested that a combination of HPA and serum PG assays plus scheduling endoscopy accordingly is a cost-effective strategy of screening for gastric cancer risk in Japan.

あらかじめ胃がんリスクを判定し、検診の必要性の少ない対象者と高い対象者を分類することは不要な検診費用を削減できるため極めて効率的な検診の運用方法である。日本の胃がんの発症率は諸外国と比較して非常に高く、発症予防と検診による早期発見に力を注ぐべき消化器疾患の１つとされている。ヘリコバクター・ピロリ菌の除菌治療による胃がんの発症予防とリスクの高い対象者へ集中的に精度の高いサーベイランスを行う検診方法の有用性が医療経済的な観点から示された。
