Oxygen-Guided Radiation Therapy

Purpose It has been known for over 100 years that tumor hypoxia, a near-universal characteristic of solid tumors, decreases the curative effectiveness of radiation therapy. However, to date, there are no reports that demonstrate an improvement in radiation effectiveness in a mammalian tumor on the basis of tumor hypoxia localization and local hypoxia treatment. Methods and Materials For radiation targeting of hypoxic subregions in mouse...
