title: Solid pseudopapillary neoplasms of the pancreas: an updated experience.
abstract: BACKGROUND
  The aim of this study is to report an update of the surgical experience at a single institution with these unusual tumors.
  
  
  METHODS
  Sixteen consecutive patients who underwent surgery for a pathologically confirmed solid pseudopapillary neoplasm (SPPN) were retrospectively reviewed.
  
  
  RESULTS
  Fifteen of the patients were female and the median age at diagnosis was 30 years (range, 14-53 years). Abdominal and back pain were the most common presenting symptoms. The tumors appeared on cross-sectional imaging as solid and cystic (n = 14) or cystic (n = 2) masses. The median tumor size was 9.5 cm (range, 5.0-24.0 cm). All 16 patients had curative resections including 3 pancreaticoduodenectomies and 13 distal pancreatectomies. Three patients required extended resections including pancreaticoduodenectomy with portal vein resection, distal pancreatectomy with tranverse colectomy, and distal pancreactomy with omentectomy. Two of the resections were R1 whereas 14 were R0. All patients were alive and disease-free at a median follow-up of 43 months (range, 3-186 months).
  
  
  CONCLUSIONS
  SPPNs should be considered in young women presenting with a large solid-cystic pancreatic mass. Aggressive en bloc resection should always be attempted including resection of concomitant metastases as patients demonstrate excellent long-term survival even in the presence of distant spread.
