Importantly, among the 35 ACC patients with a new tumor event, the survival rate was significantly lower in patients with low (n = 16) versus elevated (medium and high) (n = 22) IL-13Rα1 expression; patients with low IL-13Rα1 expression had a 12.5% survival rate whereas patients with elevated IL-13Rα1 expression had a 50% survival rate (p = 0.0356). This evidence concerns the gene IL13RA1 and adrenal cortex carcinoma.
