BACKGROUND: Retroperitoneal sarcomas are rare soft tissue tumours accounting for 10-15% of soft tissue sarcomas. Patient prognosis and treatment recommendations (including extent of surgery and neoadjuvant strategies) are determined by the pre-operative histopathological subtype and grade obtained from biopsy and thus it is important to understand the accuracy of biopsy in retroperitoneal masses. METHODS: This study presents a case series of primary retroperitoneal sarcomas managed at Peter MacCallum Cancer Centre (PMCC) between 2008 and 2019.
