Conclusion:

A total of twelve pediatric patients were treated with PDR in combination with individualized 3D-printed moulds for (HN)RMS, germ cell- and rhabdoid tumors. No unexpected side effects were observed and the local control is preserved. Individualized 3D-printed moulds using PEEK and Biomed Clear allows for continuation of pediatric brachytherapy despite changes in MDR.
