Introduction: Radiotherapy (RT) is an integral part of treatment concepts for early-stage Hodgkin lymphoma. The following analysis reports on RT-quality in the recent HD16 and 17 trials of the German Hodgkin Study Group (GHSG). Methods: All RT-plans of involved-node RT (INRT) in HD 17 were requested for analysis, along with 100 and 50 involved-field RT (IFRT) plans in HD 16 and 17, respectively. A structured assessment regarding field design and protocol adherence was performed by the reference radiation oncology panel of the GHSG. Results: Overall, 100 (HD 16) and 176 (HD 17) patients were eligible for analysis. In HD 16, 84 % of RT series were evaluated as correct, with significant improvement compared to the predecessor studies (p< 0.001). In HD 17, 76.1 % of INRT-cases revealed a correct RT design compared to 69.1 % of IFRT-cases, which was superior to prior studies (p
