  • Title: Pancreatic polypeptide in insulinomas, gastrinomas, vipomas, and glucagonomas.
    Author: Polak JM, Bloom SR, Adrian TE, Heitz P, Bryant MG, Pearse AG.
    Journal: Lancet; 1976 Feb 14; 1(7955):328-30. PubMed ID: 54738.
    Abstract:
    In 33 patients studied with endocrine neoplasms of the pancreas more than half the tumours contained pancreatic polypeptide (P.P.) producing cells, and a high radioimmunoassayable concentration of P.P. was found in the tumour extracts. Plasma was available from 28 patients, and very high circulating P.P. concentrations were found in 18. The presence of P.P. in hepatic and lymphnode metastases indicates that its production by the primary neoplasm cannot be ascribed to incidental adherence of normal P.P. cells. Measurements of plasma P.P. levels should be a new aid to diagnosis of pancreatic tumours.
