ARG2 and neoplasm: We observed that, compared to control cancer patients (surgery only), ADT-treated patients (ADT prior to surgery) had significantly lower ARG2 expression in both the non-malignant tissues adjacent to the tumor (46.4 vs 23.5 relative units; p<0.001, Mann-U) and the tumor tissues (41.7 vs 31.5 relative units; p<0.01, Mann-U) (Figure 3A).
