title: Safety and accuracy of core biopsy in retroperitoneal sarcomas.
abstract: OBJECTIVE
  Retroperitoneal sarcomas (RPSs) are large, rare tumors. The role of core biopsy for retroperitoneal masses identified by preoperative imaging is unclear and we report the safety and accuracy of core biopsies at a specialized sarcoma unit in Sydney, Australia.
  
  
  METHODS
  A retrospective analysis of a prospectively collected database was performed to identify the safety and accuracy of core biopsies in patients who were confirmed to have RPS.
  
  
  RESULTS
  Twenty-two patients underwent biopsies with no recorded morbidity or tumor seeding. RPS was correctly identified in 82%. Median follow-up was 19 months.
  
  
  CONCLUSIONS
  We demonstrate that core biopsy is safe and can identify RPSs.
