Surgical outcomes of solid pseudopapillary neoplasm of the pancreas: A single institution's experience for the last ten years

Solid pseudopapillary neoplasm (SPN) of the pancreas is a rare neoplasm that accounts for about 1 to 2 per cent of all pancreatic tumors. The aim of this study was to delineate the clinicopathological characteristics and surgical outcomes of solid pseudopapillary neoplasm of the pancreas. We retrospectively reviewed the clinicopathological characteristics and surgical outcomes of 18 patients who underwent surgery for SPN of the pancreas between January 1, 2001 and November 1, 2010. The patient group was comprised of 14 females and four males and the median patient age at diagnosis was 32.4 years (range 10-68 years). Eleven of the 18 patients were symptomatic at the time of diagnosis. The type of surgery was selected according to the location and presentation of the tumor. The resection margins were negative in all patients. One patient had distant metastasis and recurrent mass node repetitively. She underwent seven operations for recurrence of SPN during the follow-up period of 218 months. Complete surgical excision is the treatment of choice for SPN of the pancreas and can give a good prognosis.Although sometimes patients have repetitive metastases or recurrences, patients undergoing complete surgical excision of the tumor will have a good outcome.
