RESUMO
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.
RESUMO
Objective To investigate the clinical pathological features and prognosis of gastric carcinoma with neu-roendocrine differentiation (NED) and mixed gonadal neuroendocrine carcinoma of the stomach (MANECs). Methods A retrospective analysis of 61 cases of gastric carcinoma with NED and 34 cases of MANECs and their histochemistry and im-munohistochemistry were also observed. Prognosis of the 2 groups were compared by the Kaplan-Meiers survival analysis. Prognostic factors associated with patients with gastric cancer were analyzed by COX proportional hazards model. Results Tumor location, distant metastasis and lymph node metastasis were statistically different between these 2 groups (P<0.05). Syn positive expression rate is higher than CgA and CD56 in the gastric carcinoma with NED group;Postoperative survive pe-riod of the gastric carcinoma with NED is shorter than that of MANECs (P<0.05). Lymph node metastasis and distant region-al transfer is obviously correlated with prognosis (P<0.05). Conclusion Immunohistochemistry is important for the diag-nosis of these two tumor. The number of neuroendocrine cells can help to assess prognosis and guide treatment.
