[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.

Objective To investigate the MRI imaging features, and pathologic basis of the orthotropic transplantation nude mouse model with human pancreatic cancer. Methods Adopting Siemens Magnetom Trio Tim 3.0 Tesla superconductive MRI and breast coil was used to examine 30 orthotropic transplantation nude mouse models of the human pancreatic cancer, these mouse were sampled to acquire TSE-T1 -weighted and T2-weighted transverse axial images. Intraperitoneal injection of Gd DTP A was used to perform continuous dynamic enhancement scanning. Signal intensities of tumors were measured in plain scanning and each phase' s enhancement scanning images, respectively. Intensification rates of tumors were calculated. Pathologic examination of tumors was performed to be compared with the findings of MRI scanning. Results The successful rate of inoculation of 30 nude mice was 100%. The histological findings were comparable with poorly differentiated adenocarcinoma. Compared with signal of adjacent tissues, the MRI findings of the tumors were uniformly slightly hypointensity (90% , 27/30) , or unevenly (10% , 3/30) on TSE-T1WI; uniformly (20% , 6/30) or unevenly (80% , 24/30) hyperintensity with equal or more hyper signal spots on TSE-T2WI. Signal intensities on plain scanning was 228.35 ±11.71, and 1.5,3,6,9, 12 min after enhancement scanning, thesignal intensities were 258.20 ± 11.17, 301.75 ± 17.09, 358.65 ±25.13, 480.05 ± 19.01, 558.35 ± 40.49, which were significantly higher than those in plain scanning (P <0.01). The intensification rate of every phase was 0.13 ±0.04, 0.35 ±0.11, 0.56 ±0.10, 1.10 ±0.10, 1.45 ±0.18, and the difference among these phases was statistically significant (P <0.01). The significantly intensified area was the area where the tumor cells grew actively with rich capillaries; the central area without intensification was the area of necrotic tissue and/or densely packed tumor cells and few capillaries. Conclusions High resolution MRI imaging of implanted tumors can be obtained by intraperitoneal injection of contrast, and it is consistent with pathologic examinations.
