Outline of Final Research Achievements |
In this study, gastric cancer patients with disseminated intravascular coagulation (DIC) were analyzed based on comparison of clinicopathological features and comprehensive gene expression status. The results showed that patients with bone metastases and abnormal blood test results related to blood coagulation at the time of initial diagnosis were at high risk of developing DIC. Furthermore, the results of the gene expression analyses showed that gastric cancer patients with DIC were divided into two groups, one with a particularly poor prognosis and the other with a relatively good prognosis, suggesting the possibility of establishing treatment strategies targeting gene expression abnormalities characteristic of each group.

Academic Significance and Societal Importance of the Research Achievements |
本研究は、固形がんに併発したDICについて、臨床病理学的特徴に加え、網羅的遺伝子発現データに基づく解析を行った研究である。DICを併発した胃癌症例が網羅的遺伝子発現プロファイルから大きく2つの群(D群およびN群)に分かれることはこれまで知られていない。これら2つの群では治療成績が有意に異なり、特にD群は予後不良であることが示唆されたことから、D群において発現状態が変化している遺伝子群を明らかにすることで、DIC発症に関連する遺伝子発現異常が明らかとなるとともに、治療抵抗性獲得に寄与する因子およびそれらの因子を標的とした新しい治療戦略の樹立につながる可能性がある。
