SOFT TISSUE & BONE SARCOMA GROUP
EORTC 1809 – STRASS II – A randomized phase III study of neoadjuvant chemotherapy followed by surgery versus surgery alone for patients with High Risk RetroPeritoneal Sarcoma (RPS)
Retroperitoneal sarcoma is a very rare tumour, occurring in 0.5 to 1.0 per 100,000 of the population. Diagnosis and treatment are challenging. The standard of care consists currently of surgery. Overall patient survival at 5 years following surgery is between
60 and 70%.
The EORTC 1809 STRASS II study is the first official trial looking into potential benefits of chemotherapy before surgery to improve disease control and survival in patients burdened by this rare cancer.
