WHO is the trial for?
• Patients with histologically confirmed retroperitoneal sarcoma (RPS)
• No metastasis
• Previously untreated
• Tumor must be operable, suitable for radiotherapy and radiologically measurable (RECIST 1.1)
• Overall health status of the patient has to be good (WHO performance status 0-2)
• No other malignant tumor disease within the past 5 years
WHAT is the key question that this trial is attempting to answer?
Radiation therapy uses high-energy x-rays to kill tumor cells. Giving radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. It is not yet known whether surgery is more effective with or without radiation therapy in treating nonmetastatic retroperitoneal soft tissue sarcoma.
This randomized phase III trial is studying radiation therapy followed by surgery to see how well it works compared with surgery alone in treating patients with previously untreated nonmetastatic retroperitoneal soft tissue sarcoma.
WHY patients might want to participate?
This clinical trial offers patients an opportunity to access a new therapy strategy. This trial will further support the research in retroperitoneal soft-tissue sarcoma and potentially help other patients with this disease. The trial might or might not have benefit in your individual case. For more about the importance and benefits of joining clinical trials, please click here.
WHEN will the trial be open?
The study is open (recruiting) – 256 patients are expected to participate.
WHERE is the trial available?
The trial was available in 34 study centers in several countries in Europe, the USA and Canada

STUDY DESIGN: What does the study look like?
There will be 2 study arms (groups): all participating patients will be randomly divided (by a computer) in two groups. Patients in one group will be assigned to radiotherapy followed by surgery. Patients in the other group will receive surgery alone.
