ABSTRACT

Objective To summarize the methods of diagnosing and treating solid-pseudopapillary neoplasm of pancreas SPN so as to provide reference for its early clinical diagnosis.Methods We collected the clinical data of 62 patients with pathologically confirmed diagnosis of SPN treated in the First Affiliated Hospital of Xi'an Jiaotong University between Feb.2004 and Sep.2014.Then we retroactively analyzed and summarized the clinical characteristics,diagnosis and treatment of the disease.Results Among the 62 patients,55 were female and 7 were male;the mean age was (31.58±12.67) years old.The clinical features showed no specificity and the tumor was mostly detected upon physical check-up.The tumor was seen to be located mostly in the body and tail of the pancreas,and the average maximum diameter was (7.81±3.54)cm.We did not find obvious abnormality in routine pre-operative blood test results or liver and kidney functions.The imageological examination indicated tumor occupation in the pancreas.All the patients underwent surgical resection with no complications or death and had a good recovery after operation.Pathological diagnosis after operation was SPN without metastasis in lymph modes.Until the last time we followed up all the patients,we found relapse in two patients (3.2％).Conclusion SPN is a tumor that tends to affect young and middle-aged females.The malignancy grade of SPN is low,and patients with this disease show no specificity in clinical manifestation.The imageological examination is of vital importance in diagnosing SPN and surgical resection is an effective way to treat SPN.
