Retroperitoneal sarcoma: the Transatlantic Australasian Retroperitoneal Sarcoma Working Group Program.

Area of Science:

• Oncology
• Clinical Research Networks
• Sarcoma Biology

Background:

• Established in 2013, the Transatlantic Australasian Retroperitoneal Sarcoma Working Group (TARPSWG) is a collaborative network focused on improving care for retroperitoneal sarcoma (RPS) patients.
• The group aims to overcome challenges posed by the rarity of RPS through international cooperation.

Observation:

• TARPSWG has conducted retrospective studies on primary and recurrent RPS, enhancing knowledge of prognosis, treatment efficacy, and tumor biology.
• The network significantly contributed to the successful recruitment and completion of the phase III STRASS trial, evaluating neoadjuvant radiotherapy for RPS.
• A prospective registry for primary RPS patients is actively being populated by TARPSWG members.

Findings:

• Consensus papers have been developed by TARPSWG, offering management recommendations for primary, recurrent, and metastatic RPS.
• These recommendations integrate insights from sarcoma experts across Europe, North America, Asia, and Australia.
• The collaborative efforts have led to a better understanding of patient prognosis and treatment outcomes in RPS.

Implications:

• TARPSWG has emerged as a leading international network in retroperitoneal sarcoma research.
• The group's work facilitates overcoming the limitations imposed by the rarity of RPS.
• Continued collaboration through TARPSWG promises further advancements in RPS research and patient care.
