In addition, the calculations demonstrated for this patient collective that the intensity of COX-2 expression of sTILs has positive correlations with the general percentage of COX-2 expression in tumor tissue (* p = 0.001), the IRS score of COX-2 expression in tumor tissue (* p = 0.014), and the combined cytoplasmic expression of COX-2 and PPARγ (* p = 0.011). Here, PTGS2 is linked to neoplasm.
