| Research Abstract |
Hypoxic fraction in solid malignant tumor is strongly correlated with poor treatment effects of irradiation and prognosis. In order to develop an innovative radiation therapy strategy to overcome intra-tumor hypoxia, we have accomplished (1)evaluation of the presence and dynamic change of hypoxic region in the lung orthotopic tumor model, (2) development of the hypoxia targeted protein drug and the promotion of translational research, (3)optimization of the combination of the hypoxia targeted protein drug and irradiation, (4)establishment of Intensity Modulated Radiation Therapy(IMRT) method for simultaneous dose escalation in intra-tumor hypoxic region, (5)development of a treatment planning technique which can handle target motion and a moving phantom system for dose verification of moving target.
