A Novel Role of Interleukin 13 Receptor alpha2 in Perineural Invasion and its Association with Poor Prognosis of Patients with Pancreatic Ductal Adenocarcinoma.

Similarly, the percentage of positive fields for IL-13Rα2 expression in 2+ and 3+ positive specimens in IHC analysis demonstrated a highly significant trend in these specimens (well differentiated = 35.0%, moderately differentiated = 82.0% and poorly differentiated = 94%; exact p < 0.0001) compared to PDAC samples with negative values of IL-13Rα2 (≤ 1+) ( Figure 1 D).
