Summary
Brief summary
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 II/III is a prospective randomized, multi-center, open-label and active
controlled two arms study in patients with locally advanced soft tissue sarcoma (STS) of the
extremity and trunk wall. Patients will be randomized to receive either NBTXR3 as intratumor
injection, activated by external beam radiation therapy or external beam radiation therapy
alone, as preoperative treatment. Once the radiotherapy treatment is completed, tumor surgery
will be performed in all patients.
