Randomized Controlled Trial of Repeat vs. Single Quadratus Lumborum Block to Reduce Opioid Prescriptions After Open Resection of Retroperitoneal Sarcoma ("RESQU-SARC" Trial)

M.D. Anderson Cancer Center·interventional·Posted Dec 6, 2019·Updated Apr 14, 2026

In Brief

A Phase 2 clinical trial evaluating Liposomal Bupivacaine, Quadratus Lumborum Block, and 1 other intervention for Retroperitoneal Sarcoma. Active but no longer recruiting, targeting 113 participants across 1 site.

Detailed Summary

This phase II trial studies how well a repeat or single liposomal bupivacaine injection (quadratus lumborum block) works in reducing opioid prescriptions after surgery in patients with retroperitoneal sarcoma. Liposomal bupivacaine is a numbing medication. Giving a second injection block may decrease dependency on opioid medications for pain relief after surgery and prevent long-term use and addiction.
