Clinical Pathological Characteristics in Pancreatic Carcinoid / 中山大学学报(医学科学版)

ABSTRACT

[Objective] To explore the clinical pathological characteristics and treatment of pancreatic careinoid. [Methods] Eight patients with pancreatic careinoid were recruited between January in 1997 and December in 2007 for retrospective analysis which involved tumor markers, inanunohistostaining, accompanied with other tumors, misdiagnosis, metastasis, in-hospital mortality rate, and so on. The relevant literatures were simultaneously reviewed to comprehend the clinical pathological characteristics of pancreatic carcinoid. [Results] Tumor markers CEA, CA199, CA125, and CA72-4 in pancreatic carcinoid were 0%, 25%, 12.5%, and 0%, respectively. Specimen immanohistostaining Syn, CgA, NSE, and CK in pancreatic carcinoid were 25%, 62.5%, 75%, and 75%, respectively. Two pancreatic carcinoids were accompanied by other tumors in 8 cases. The misdiagnosis rate of pancreatic carcinoid (7/8) was markedly high. Pancreatic carcinoid possessed high metastasis (50%), high in-hospital mortality rate (37.5%) and low radical operation undergone (62.5%). [Conclusions] Pancrcatic carcinoid was accompanied with high misdiagnosis rate and poor prognosis. Routine sero-markers did not help discover pancreatic carcinoid early. The final diagnosis depended on specimen immunohistostaining with Syn, CgA, NSE, and CK.
