Letter to the editor: Hypoxia kinetics and histology in combined radiotherapy and oxidative phosphorylation inhibition effects on antitumor immunity

摘要

In response to the recent paper by Chen et al investigating the triple combination of oxidative phosphorylation inhibition, immunotherapy and radiotherapy, we would like to stress that after irradiation, a strong reduction in hypoxia (within 24 hours) can be followed by a strong increase (several days). This is especially the case with larger fraction sizes of radiation therapy, which are often applied in combination with immunotherapy, and is likely to be tumor dependent. All together this may strongly affect the synergistic effect of such a triple combination therapy.
