The Transatlantic Australasian Retroperitoneal Sarcoma Working Group (TARPSWG) is a collaboration of surgical oncologists, medical oncologists and radiation oncologists along with pathologists and basic scientists established in 2013 with the following aims:
1. evaluate current outcomes and evidence in the management of patients with primary, locally recurrent, and metastatic retroperitoneal sarcoma
2. develop evidence-based expert consensus guidelines to standardize care of this complex and rare disease globally,
3. develop prospective clinical trials to address seminal clinical questions,
4. enhance international collaboration and patient enrollment in prioritized clinical trials,
5. facilitate translational scientific research to advance fundamental knowledge and develop novel therapies, and
6. mentor junior faculty investigators and trainees.
From an original 8 institutions, membership has now expanded across Europe, North America, Central America, South America, Australia and Asia to 128 institutions.
Consensus documents have been published concerning the management of primary, locally recurrent and metastatic RPS.
