Myxoid Liposarcoma of Soft Tissue Clinical Trial
Official title:
Dose Reduction of Preoperative Radiotherapy in Myxoid Liposarcomas
To study the feasibility of reducing the dose of preoperative radiotherapy in MLS (Myxoid Liposarcomas) from 50 Gy to 36 Gy while maintaining comparable clinicopathological responses.
- A Bayesian approach is considered for the analysis of this trial. The aim is to provide a stopping rule for inefficacy of the new dose. - Two aspects are important to elucidate the mechanism of this treatment: dynamic investigations of perfusion and vasculature. Apart from participation to the dose reduction paragraphs of this study, patients will be also asked to undergo, at clinically relevant dose points, dynamic contrast enhanced (DEC) MRI scans and separately tumor biopsies. ;
