Study Summary

This is a multicenter, randomized, open label phase lll trial 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.

Eligible Conditions
  • Retroperitoneal Sarcoma
  • Leiomyosarcoma
  • Liposarcoma

Eligibility Criteria

Age 18+ · All Participants · 10 Total Inclusion Criteria

Mark “Yes” if the following statements are true for you:
You are diagnosed with high-risk leiomyosarcoma or liposarcoma in the retroperitoneal space, or infra-peritoneal spaces of the pelvis.
Any learning management system grade can be included.
The size of your LMS tumor must be at least 5 cm.
MDM2 and CDK4 expression should be confirmed through IHC, with MDM2 amplification highly recommended.
All Grade 3 Deep Lingual Papillae are eligible.
The grade 2 DDLPS has a FNCLCC score of five, no necrosis on biopsy but visible necrosis through imaging.
Your tumors possess a CINSARC-high gene profile, which is associated with increased risk.
Representative samples of either formalin-fixed, paraffin-embedded tumor blocks or unstained tissue slides must be present at the start for histological central assessment.
The tumor has not extended through the sciatic notch or across the diaphragm.
Pre-operative imaging (CT-abdomen, potentially also with MRI) is used to determine resectability of the tumor
