Abstract:
Objective To study the clinic-pathological features,diagnosis,treatment,and prognosis of solid-pseudopapillary tumors of pancreas.Methods A retrospective clinical and pathological analysis was made on 10 patients(1 ∶ 4),admitted from January 2003 to December 2011.There were 2 male and 8 female patients,aging from 16 to 65 years with a mean of 32.6 years.Results The main symptom was mild abdominal pain (4/10).B-US,CT,MRI demonstrated that all tumors were located in pancreas (3 cases at the head,1 case at the neck,and the others at the body and tail),and well circumscribed,contained some degree of cystic degeneration.All the 10 patients had curative resections including,3 patients received standard duodenopancreatectomy,1 patients received tumor resection and pancreaticojejunostomy,2 patients received distal pancreatectomy,and 4 patients received distal pancreatectomy plus splenectomy.The specimens appeared as solid (3/10) or solid and cystic(7/10),and the biggest tumor diameter was between 3.3-14.0 cm with an average about 5.91 cm.Immunohistogically,the tumors were positive for Neuron-Specific Enolase (NSE,9/9)、Vimentin (9/9),CD56(7/7),Synaptophysin (Syn,5/8),Progesterone Receptor (PR,5/6),CD10 (4/6),Chromogranin A (1/4).Totally 10 cases were followed up with a average period of 36.6 months without tumor recurrence.Conclusions Solid-pseudopapillary tumor of pancreas is a rare tumor with low grade malignancy.Accurate diagnosis was difficult before operations.Surgical resection is recommended as the main treatment,and the prognosis is good.
