Figure 5. — Relationship between pIgR expression and prognosis. (A) Immunohistochemical staining for pIgR in pancreatic cancer tissues (magnification, ×100). The left and right images show the same sample tissue blocks and correspond to the staining intensity. Left, H&E staining; right, immunohistochemical staining for pIgR. (B) Criteria for determination of pIgR expression levels. The pIgR expression levels in immunostaining were determined based on the intensity of staining and percentage of stained cells. The staining intensity and staining percentage criteria are presented. (C) Kaplan-Meier survival analysis in patients with pancreatic cancer (n=77, revealing OS based on the expression of pIgR protein. Red line, high-expression group (n=47), blue line, low-expression group (n=30). pIgR, polymeric immunoglobulin receptor; H&E, hematoxylin and eosin; OS, overall survival. *Statistically significant.
