Abstract Castleman disease (CD) is an uncommon benign lymphoproliferative disorder, which usually presents as solitary or multiple masses in the mediastinum. Peripancreatic CD was rarely reported. Herein, we report two cases of unicentric peripancreatic CD from our center. A 43-year-old man and a 58-year-old woman were detected to have a pancreatic mass in the routine medical examinations. Both of them were asymptomatic. The computed tomography and ultrasonographic examination revealed a mild enhancing solitary mass at the pancreatic head/neck. No definite preoperative diagnosis was established and Whipple operations were originally planned. The intraoperative frozen section diagnosis of both patients revealed lymphoproliferation. Then the local excisions of mass were performed. Histological examination revealed features of CD of hyaline-vascular type. No recurrence was found during the follow-up period. CD should be included in the differential diagnosis of pancreatic tumors. Local excision is a suitable surgical choice.

Objective: To investigate the effects of tacrolimus-based immunosuppression regimens after orthotopic liver transplantation and search a reasonable regimen of combination therapy and suitable blood concentration of tacrolimus., Methods: Ninety-four adult recipients of cadaveric livers were randomly divided into 3 groups to undergo different tacrolimus-based immunosuppression regimens: dual (tacrolimus + glucocorticoid), triple [tacrolimus + mycophenolate mofetil (MMF) + glucocorticoid]; quadruple [tacrolimus + MMF + glucocorticoid in addition of induction treatment by daclizumab]. The efficacy and safety of the 3 groups 6 months after the transplantation were compared., Results: The frequencies of acute rejection were 25.9%, 11.1%, and 7.5% for the dual, triple, and quadruple therapy groups, that of the quadruple therapy group being significantly lower than that of the dual therapy group (P = 0.038). There were no significant differences in the rates Three months after transplantation, the levels of ALT and total cholesterol of the dual therapy groups were significantly higher than those of the quadruple therapy group (P(ALT) = 0.011, P(Tch) = 0.002). Within the first month post-operatively the concentration of tacrolimus of the triple therapy group could be controlled at the level 8 ng x ml(-1)-13 ng x ml(-1)., Conclusions: Quadruple tacrolimus-based immunosuppression regimen is the most effective and safest, followed by the triple therapy and dual therapy. Low-dose tacrolimus combination therapy provides an effective protection to the liver graft with mild drug toxicity to the patient.

Objectives: To understand the characteristics of primary liver cancer (PLC) in the elderly and summarize the experience in treatment of such patients., Methods: The clinical data of PLC in the elderly group (>/=60 years, 125 patients) and the young group (0.05)., Conclusions: Hepatectomy is a choice of treatment for PLC in the elderly based on their liver function. AFP and B-ultrasonography are important methods for the diagnosis of PLC in the elderly.
