要旨●dMMR型胃癌の組織学的特徴を明らかにするために,胃癌切除検体202例および生検検体70例を対象に臨床病理学的因子および組織学的因子を検討した.切除検体でdMMR型胃癌を反映する臨床病理学的因子は性別,年齢であり,組織型は髄様癌が多くみられた.組織学的因子は乳頭管状構造,TILおよびCD8陽性細胞数であった.生検検体においてはTILがdMMR型胃癌を反映した.また,切除検体および生検検体の多変量解析結果から,dMMR型胃癌の予測式を切除検体,生検検体ごとに算出した.本稿で検討した切除検体および生検検体の臨床病理学的・組織学的特徴,dMMR型胃癌の予測式はdMMR型胃癌の診断向上につながると思われた.
