Clinicopathological study of gastrointestinal pancreatic carcinoma with neuroendocrine differentiation and mixed adenocarcinoma of the pancreas and pancreas / 中国生化药物杂志

ABSTRACT

Objective To investigate the clinicopathological features of gastrointestinal carcinoma with neuroendocrine differentiation (NED) and mixed adenocarcinoma of the pancreas and pancreas (MANEC). Methods Clinical and pathological data of 29 cases in Zhejiang Chinese medicine hospital with gastrointestinal pancreatic cancer with neuroendocrine branch and 7 cases with gastrointestinal pancreatic MANEC patients were analyzed retrospectively. Hematoxylin eosin staining of the tissue (HE) and immunohistochemistry (IHC) were observed, the relationship between IHC index and tumor distant metastasis and clinical pathological indicators between. Results Gastrointestinal pancreatic cancer with NED and MANEC in patients with various clinicopathological parameters and IHC expression rate difference was not statistically significant;neuroendocrine index expression difference between the positive rate and clinical pathological factors were not statistically significant; there was no significant difference between distant metastasis and clinical pathological factors. Conclusion Combined with morphological HE staining and immunohistochemical IHC staining, gastrointestinal carcinoma with NED and MANEC has high heterogeneity. Clinical staging and grading are the major prognostic factors. Early diagnosis and treatment can improve the prognosis of patients.
