Soft Tissue Sarcoma Adult Clinical Trial
— PRESTOOfficial title:
Short Course Pre-operative RadiothErapy for Soft Tissue SarcOmas - a Phase I/II Trial (PRESTO)
Soft tissue sarcomas (STSs) are malignant tumours that arise in any of the mesodermal tissues in the body including muscles, fibrous tissues, bone and cartilage, adipose tissue, and blood vessels, most frequently in the extremities (40%), trunk and retroperitoneum (40%). Traditionally, the prescription schedule for conventional preoperative RT is a regimen of 50 Gy in fractions of 1.8-2 Gy per day. Concerns regarding this regimen include the delay to definitive surgery and the higher rate of wound complications compared to post-operative radiotherapy. Hypofractionated RT is a prescription schedule in which the total dose of radiation is delivered in larger doses per fraction in fewer fractions allowing the delivery of a higher biologically effective dose (BED) to the tumour than with conventional RT [7] during a shorter period of time.
