Below are recruiting retroperitoneal sarcoma clinical trials, each written for real people, not researchers. We’re tracking 14 recruiting studies, each written for real people, not researchers, below.
Recruiting studies
- NCT01659203RecruitingPhase 1/Phase 2
Proton or photon radiation for retroperitoneal sarcoma
This trial tests two types of external beam radiation—protons or photons—in people with retroperitoneal (in the back of the abdomen) soft tissue sarcoma. It’s an early-phase study meant to see how well the radiation can control measurable tumors while tracking safety.
Chicago, IllinoisAges 18 years+ - NCT05844813Enrolling by invitationPhase 4
Neoadjuvant chemo plus targeted treatment for high-risk retroperitoneal sarcoma
This trial tests giving chemotherapy together with a targeted treatment before surgery for people with a high-risk retroperitoneal sarcoma. The goal is to shrink or control the tumor so surgery can potentially remove it with minimal remaining disease (R0/R1).
Beijing, Beijing MunicipalityAges 18–75 - NCT06943612Recruiting
Studying colon surgery in retroperitoneal sarcoma patients
This study looks at people with rare abdominal sarcomas who also had part of their colon removed during surgery. It aims to understand how these combined surgeries affect outcomes, helping doctors better care for future patients.
Mannheim, Baden-WurttembergAges 18 years+ - NCT04031677RecruitingPhase 3
Surgery with or without chemotherapy for high-risk retroperitoneal sarcoma
This trial studies whether adding chemotherapy before surgery helps people with high-risk retroperitoneal (abdominal-area) leiomyosarcoma or liposarcoma. The goal is to improve outcomes while comparing surgery alone versus surgery plus neoadjuvant chemotherapy.
Birmingham, AlabamaAges 18 years+ - NCT05224934Recruiting
Radiation before surgery for retroperitoneal soft-tissue sarcoma
This trial tests giving a shorter, lower-dose radiation treatment before surgery for a retroperitoneal (deep belly/back space) soft-tissue sarcoma. The goal is to shrink or control the tumor and make surgery more effective and safe.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06327477RecruitingPhase 1/Phase 2
A new type of radiation for newly diagnosed retroperitoneal sarcoma
This trial tests a new way of giving radiation called proton spatially fractionated radiotherapy (P-SFRT) combined with standard radiation for people with a type of sarcoma in the back of the belly. The goal is to see if this combination can treat the tumor more effectively.
Chicago, IllinoisAges 18 years+ - NCT06812052RecruitingPhase 1
Short course radiation before surgery for retroperitoneal sarcoma
This study tests whether a short course of radiation before surgery can treat retroperitoneal sarcoma (a rare cancer in the back of the belly). It is for people whose tumor is removable and who have not had previous radiation in the same area.
Boston, MassachusettsAges 18 years+ - NCT06436846Recruiting
Genomic risk in retroperitoneal sarcoma
This study is looking at genetic risk factors in people with retroperitoneal liposarcoma who are having surgery to remove the tumor. The goal is to understand how genes affect the disease and possibly guide future treatments.
Philadelphia, PennsylvaniaAges 18 years+ - NCT03838718Recruiting
Registry study for adults after retroperitoneal sarcoma surgery
This study follows adults who have had surgery for a retroperitoneal sarcoma. It collects clinical and imaging information after treatment to better understand outcomes and guide future care.
Los Angeles, CaliforniaAges 18 years+ - NCT07432932Recruiting
Personalized treatment before surgery for high-risk sarcoma
This trial tests a precision medicine approach by giving targeted therapy before surgery for high-risk soft tissue sarcoma. The goal is to see if matching treatment to your tumor's type can improve outcomes.
LondonAges 18 years+ - NCT06025747RecruitingPhase 1
Abemaciclib plus radiation for liposarcoma before surgery
This trial tests a combination of the targeted drug abemaciclib and radiation therapy before surgery for people with a specific type of liposarcoma. The goal is to see if this combination can shrink the tumor and help make surgery more effective.
Seattle, WashingtonAges 18 years+ - NCT06753136Recruiting
Electrochemotherapy for internal organ tumors
This trial tests a treatment called electrochemotherapy for tumors in internal organs (like the liver or pancreas) when standard treatments are no longer possible. It uses a drug called bleomycin plus electric pulses to target cancer cells.
PadovaAges 18–99 - NCT04219202Recruiting
Pre-surgery radiation for retroperitoneal soft tissue cancer
This study tests giving special radiation (ions) before surgery for a specific cancer in the back of the abdomen (retroperitoneal soft tissue sarcoma). The goal is to shrink or control the tumor so surgery may be safer or more effective.
HeidelbergAges 18 years+ - NCT07377747Recruiting
Study of treatment for recurrent retroperitoneal liposarcoma
This study looks at how well standard treatments work for people whose liposarcoma has come back in the same area. It helps doctors understand best ways to manage this rare cancer.
Atlanta, GeorgiaAges 18 years+

Common questions
- Are there clinical trials for retroperitoneal sarcoma?
- Yes. Clin2 currently lists 14 recruiting retroperitoneal sarcoma studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a retroperitoneal sarcoma trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a retroperitoneal sarcoma trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
