title: Surgical Outcomes of Solid Pseudopapillary Neoplasm of the Pancreas: A Single Institution's Experience of 16 Cases.
abstract: BACKGROUND
  Solid-pseudopapillary tumor (SPT) of the pancreas is a rare tumor, generally characterized by a well-encapsulated mass. The aim of the current study was to analyse the clinicopathological characteristics and treatment outcomes of patients with SPT. In this study, we report our clinical experience with 16 cases of SPTs.
  
  
  METHODS
  Sixteen patients who underwent surgery for pathologically confirmed SPT were included. Data of the patients were reviewed from the prospectively recorded database. Patients' demographics, laboratory values, clinical presentation, radiological imaging findings, surgical treatment, perioperative complications, pathological features, post-operative course, and long-term survival were collected and analyzed. Statistical analyses were performed using the computer program Statistical Package for Social Sciences (SPSS) 16.0 for Windows.
  
  
  RESULTS
  The tumors ranged from 2 to 11 cm in diameter and were located in the head in ten patients (62.5%), the neck in two patients (12.5%), and the body or tail in four patients (25%). All patients were women whose ages ranged from 21 to 79 years (mean age was 41.62 ± 15.08). Patients had resection margins free of tumor resections and there were no preoperative or postoperative mortalities. There was no recurrence or metastasis after the surgical resection. All patients were alive at a mean follow-up of 49.06 ± 29.53 months (range 6 to 99).
  
  
  CONCLUSIONS
  SPT is a rare pancreatic neoplasm with a low malignant potential, and is common in young women. If SPT is diagnosed before surgery, complete surgical resection, generally enucleation is the most effective therapy for SPT.
