Summary
Brief summary (as posted)
RATIONALE: Radiation therapy given before surgery of soft tissue sarcoma decreases the size of the tumor mass and the presence of malignant cells in its peripheral region. NBTXR3 and radiation therapy may kill more cancer cells and increase the tumor shrinkage rendering surgery more feasible or easier and achieve better local control of the tumor. PURPOSE: This Phase I trial aims at evaluating the feasibility of the NBTXR3 injection in the tumor, safety and the adequate dose of NBTXR3 when given with radiation therapy.
