Sponsor's own description

Based upon the preliminary data derived from first SCOPES clinical trial and the results of patients treated during the recent COVID-19 pandemic, patients with soft tissue sarcomas (STS) can be preoperatively irradiated in a modestly hypofractionated schedule of 14 x 3 Gy. From a toxicity and efficacy point of view, this regimen equals the outcomes after a conventionally fractionated regimen of 25 x 2 Gy in five weeks. Moreover, the rationale for investigating (modest) hypofractionation in the clinic comes both from a logistic point of view (patient convenience and a lower pressure on radiotherapy equipment), form prior phase II clinical evidence and from (cellular) radiobiological observations. There is phase II trial evidence suggesting that even more (ultra-) hypofractionation to 5 x 6 Gy is also safe and effective. Within this study, patients will be randomized to receive either the modestly hypofractionated conventional schedule of 14 x 3 Gy or an even shorter preoperative regimen of 5 x 6 Gy, in the hypothesis that both the postoperative wound complication rate until 120 days after surgery, as well as the local control probability at two years are comparable in both arms.
