Although we could not single out any gene with a specific up- or downregulation for patient E7, who had the highest late toxicity grade, the nCounter analysis identified two genes, CD40 and OAS2, following the same pattern of expression with a slight increased expression of 1.3- and 1.4-fold in the endometrial cancer patient E9 at 48 h (Figures 3A,C). Here, CD40 is linked to endometrial cancer.
