  • Title: Clinico-pathological and histochemical studies on hypertrophic duct epithelium in human non-endocrine pancreas cancer.
    Author: Hisata Y.
    Journal: Bull Tokyo Med Dent Univ; 1979 Jun; 26(2):139-48. PubMed ID: 87280.
    Abstract:
    The hypertrophic duct epithelium of the pancreas, including the pyloric gland metaplasia, mucous cell hypertrophy and ductal papillary hyperplasia were studied clinico-pathologically and histochemically to examine their precancerous character. A total of 180 surgical and autopsy specimens (90 pancreata with cancer and 90 pancreata without cancer) were analysed. The overall incidence of these three types of hypertrophic epithelium in the pancreas cancer was much higher than that in the pancreas without cancer. These hypertrophic lesions appeared most frequently in the interlobular duct. The histochemical study revealed the presence of a new type of glycoprotein in these hypertrophic duct epithelia, however, this substance was not detected in the cancer cells nor in the normal epithelium. This suggests that these hypertrophic lesions may not be the precursors of cancer but rather the coexistent lesions of pancreas cancer.
