A comparison of the average number of radiotherapy fractions (5×2 Gy per week) required for severely hypoxic vs moderately hypoxic tumours, for onset times of accelerated repopulation (AR) and reoxygenation (ROx) between 0 to 2 weeks. No significant difference was found between these two tumour types, using the moderately and severely hypoxic tumour oxygenation histograms shown in Figure 1.
