Clinical Trials

The purpose of this study is to assess whether preoperative chemotherapy, as an adjunct to curative-intent surgery, improves the prognosis of high risk DDLPS (dedifferentiated Liposarcoma) and LMS (Leiomyosarcoma) patients as measured by disease free survival. After confirmation of eligibility criteria, patients will be randomized to either the standard arm or experimental arm.

The purpose of this study is to prospectively collect standardized clinical data and radiological and pathological material from primary retroperitoneal sarcomas RPS patients treated with surgery at reference centers. Patient outcome will be evaluated in terms of overall survival (OS), disease-free survival (DFS), crude cumulative incidence (CCI) of local recurrence (LR) and distant metastasis (DM).

This research study is a Phase I clinical trial. Phase I clinical trials test the safety of an investigational intervention. Phase I studies also try to define the appropriate dose of the investigational therapy to use for further studies. "Investigational" means that the intervention is still being studied and that research doctors are trying to find out more about it.

Retroperitoneal sarcomas are soft tissue tumors located at the far back of the abdomen. Typically, patients with retroperitoneal sarcomas either have surgery for the removal of their tumors alone, or have their tumors removed, followed by standard radiation therapy, ...

The purpose of this study is to create a research registry to prospectively collect research biospecimens and corresponding clinical data from subjects with an undiagnosed tumor or undifferentiated mass.
