Outline of Final Research Achievements |
Pancreatic cancer is a malignant tumor with a particularly poor prognosis. The role of 18F-FDG PET examination in the treatment of pancreatic cancer is not only to find the primary tumor or metastatic site, but also to determine the efficacy of treatment and to evaluate prognosis. In this study, we applied the 18F-FLT PET, which can evaluate cell proliferative capacity, to pancreatic cancer patients and investigated its usefulness in determining the efficacy of treatment. The results suggested the possibility of predicting response by combining pre- and post-treatment 18F-FLT PET indices.

Academic Significance and Societal Importance of the Research Achievements |
膵癌診療における18F-FDG PET検査の役割は、原発巣、転移部位の検索に加え、治療効果判定や予後評価に用いられている。しかし、膵癌患者には高血糖や糖尿病を合併することがあり、18F-FDG PET検査においてさらなる精度向上が求められる。今回、細胞増殖能を評価できる18F-FLT PET検査の有用性が膵癌患者において示された。特に術前補助療法の効果判定における有用性が示され、個別化医療に応用できる可能性が示唆された。
