Outline of Final Research Achievements

The effect of chemotherapy in patients with cancers was different among patients. We speculated that tumor blood flow would influence a delivery of anti-cancer drug, and studied a relationship between tumor blood flow and prognosis after chemotherapy. Tumor blood flow was measured by means of positron emission tomography with Oxygen-15 labelled water in 11 patients with lung cancer. Five of 11 patients were treated by standard chemotherapy, and other six patients were treated by standard chemotherapy and ant-tumor blood vessel growth inhibitor (Bevacizumab).
Previous study indicated better prognosis after adding Bevacizumab (Sandler at al., N Engl J Med,2006). However, our study indicated that reduced tumor blood flow was found in three patients and resulted in poor prognosis. We proved in small population that tumor blood flow may influence an effect of chemotherapy.

Academic Significance and Societal Importance of the Research Achievements

抗がん剤による化学療法の効果は、患者さんごとに異なる。患者さんごとに腫瘍の血流量が異なり、抗がん剤の輸送量が個人ごとに異なるためと考えられる。本研究は、陽電子放射断層法を用い、定量的に腫瘍の血流量を測定する方法を開発し、腫瘍血流量と抗がん剤の効果の関係を明らかにすることである。
本研究では、化学療法を受けた患者さんの内、腫瘍血流量が低下している症例では生命予後が低下していた。これは抗がん剤の輸送量が低下していること、血流低下領域の腫瘍細胞は低酸素状態にあり、化学療法抵抗性があることが考えられる。
