Mesothelin and GPR30 staining among a spectrum of pancreatic epithelial neoplasms.

Introduction: Our study attempts to characterize mesothelin and GPR30 / estrogen receptor (ER) staining in pancreatic pathology.

Materials And Methods: Immunohistochemical staining for mesothelin, GPR30, and ER was performed on a variety of pancreatic lesions.

Results: 24 of 42 (57%) adenocarcinomas stained for mesothelin, while 0 of 16 non-carcinomas (0%) stained (p = 0.
