| Outline of Final Research Achievements |
Since prognosis of lung cancer has improved in the past few decades, the opportunity to encounter late recurrence has also increased. Dormancy, a phenomenon that cancers achieve resistant to treatment and sleeps inside the body for few years had been frequently discussed in cancers with slow progression; ie. breast cancers or prostatic cancers, but not for lung cancers. In this study, we discovered that some human adenocarcinoma cell lines express dormant characteristics in vivo and in vitro, suggesting dormancy may also exists in lung cancers.

| Academic Significance and Societal Importance of the Research Achievements |
肺癌のdormancyに関する研究は今後の肺がん患者の予後改善のためには必要不可欠であるが、進行の早い肺癌では適切なdormancyモデルは存在しない。本研究により得られたヒト肺癌細胞dormancyモデルを今後さらに解析し、確立することで肺がん研究のさらなる発展に繋がると考えている。
