Conclusion: To our knowledge, this is the first time that MCT dose-volume constraints were derived for STSE. In the future, we plan to increase the validation cohort and reduce the imbalance observed in the two cohorts, particularly in technique. For now, the use of a Dmax constraint can reduce the risk of grade 2+ STF for post-operative RT delivered to 60 or 66Gy.
