Manipulation of tumor oxygenation and radiosensitivity through modification of cell respiration. A critical review of approaches and imaging biomarkers for therapeutic guidance.

What Researchers Did

This review critically examined strategies to manipulate tumour oxygenation and radiosensitivity by modifying cell respiration and discussed relevant imaging biomarkers.

What They Found

Mathematical modeling indicated that reducing oxygen consumption is more effective than increasing oxygen delivery for alleviating tumour hypoxia. The review identified several promising strategies targeting mitochondrial respiration that have shown improved tumour oxygenation and increased sensitivity to irradiation. It also discussed the utility of imaging biomarkers like Positron Emission Tomography and Magnetic Resonance for guiding these therapeutic approaches.
