Clinical, pathological and radiological data points were recorded for all patients since the inception of SPARC.

Majority were from the metropolitan area (182) followed by regional NSW (87), interstate (20) and five internationals. 141 operations were performed during this period compared to 119 operations from 2010 to November 2020 in RPAH. The inception of the SPARC program has resulted in exponential growth in operations, improving from the previous rate of 15 cases annually to 35. Liposarcomas followed by leiomyosarcomas are the most common types of sarcomas resected. The majority were extended resections (81.6%) and 22% were pelvic exenterations. Overall R0 rate is 54.6%, R1 38.3% and R2 1.4% (131 (92.9%) had R0\/R1 resections.
