STREXIT2

Retroperitoneal sarcomas are rare diseases to which the current standard treatment is surgery.

STREXIT2 project

STREXIT2 is proposed to amend the ongoing phase III EORTC clinical trial STRASS2 investigating the added value of neoadjuvant chemotherapy before surgery for high-risk retroperitoneal sarcoma and to add an observational arm STREXIT2 that will capture real world data from patients not participating to STRASS2.

About retroperitoneal sarcomas

Retroperitoneal sarcomas are rare diseases refractory to treatment with dismal prognosis. Surgery is the only standard approach to primary disease. We are proposing an innovative pragmatic approach supplementing a standard phase III clinical trial with an observational cohort.

Economic Evaluation

We will perform health economics analysis assessing the economic value of different treatment scenarios based on STRASS2 and STREXIT2. If successful, the outcomes of the project will define a new evidence-based standard of care for high-risk retroperitoneal sarcomas.
