Outline of Research at the Start

肺機能画像として4次元CTによる肺換気画像と肺血流シンチによる肺血流画像を用いて高肺機能領域(以下、機能肺)を描出し、機能肺の割合が低い患者ほど同部への照射線量が低いにも関わらず放射線肺臓炎を来すことを臨床的に証明した。本研究では、機能肺に対する照射線量の低減が放射線肺臓炎の抑制につながるという仮説のもと、強度変調放射線治療(IMRT)により機能肺を選択的に低減させ、実臨床において放射線肺臓炎の低減につながるか否かを前向きに検証する。本研究の有効性が実証されれば、既に本格化した高齢化社会において患者の予備能に応じたオーダーメイド放射線治療の実現に貢献すると考える。

Outline of Final Research Achievements

This study is a multicenter prospective trial titled 'Phase II Trial of Intensity-Modulated Radiation Therapy Using Functional Lung Imaging for Locally Advanced Unresectable Non-Small Cell Lung Cancer', aiming to investigate whether reducing the radiation dose to the functional lung selectively using IMRT based on lung functional imaging decreases the frequency of severe radiation pneumonitis (≧Grade 3) in patients with inoperable or refuseable but potentially curable locally advanced non-small cell lung cancer. The registration period is 5 years with a planned enrollment of 75 cases. Four institutions, Kochi University, Hiroshima University, Tohoku University, and Cancer and Infectious Diseases Center Komagome Hospital, are participating in this study. Patient enrollment began in October of the first year of Reiwa era, and as of the end of March in the fiscal year 2023, 27 cases have been registered.

Academic Significance and Societal Importance of the Research Achievements

慢性閉塞性肺疾患(COPD)を有する低肺機能肺癌患者が増加し、その多くは手術適応とならず、放射線治療の役割が非常に重要である。しかし、COPDは放射線治療にとっても放射線肺臓炎の危険因子であるため、正常肺への照射線量の軽減が重要となる。また、2018年にIII期非小細胞肺癌に対する化学放射線治療後に免疫チェックポイント阻害薬の投与により、生存割合の有意な改善が報告され、約30年ぶりに標準治療が変わった。ただ、免疫チェックポイント阻害薬はGrade2以上の放射線肺臓炎を生じた場合は投与不可となることから、放射線肺臓炎を低減することを目指す本研究は本格的な高齢化社会を迎えた本邦において重要である。
