Current Clinical Challenge
Tumors resistance to Cancer Radiation Therapy
Radiotherapy is employed in the treatment of over half of all cancer patients. However, resistance of tumor cells to radiation, which is mainly attributed to the lack of oxygen in the tumor (tumor hypoxia) is a major cause of treatment failure. In another word, oxygen is the key requirement for radiation-mediated cell death. Despite significant technical advances, little progress has been made in identifying and defining optimal targeted therapy and radiotherapy combinations to improve the efficacy of cancer treatment.
The Future Direction in Radiation Therapy: MRI-Guided Radiation Therapy
MRI-guided radiation therapy (MRIgRT) is a brand new technology in the field of radiation oncology. Due to this fascinating development, radiation oncologist are able to see real time motion of tumor during the treatment even patient movement, or normal breathing cycle. This technology is demolishing the risk of irradiating surrounding normal tissue area.
