Treatment of upper gum carcinoma with high-dose-rate customized-mold brachytherapy

Purpose To design an applicator for the treatment of tumors of the upper gum (UGCs) with high-dose-rate (HDR) brachytherapy. Methods and Materials A customized mold with four 6-Fr catheters was built. The two halves of the paired catheters form a functional loop without sharp curves. Results An adequate dose to the surface of the tumor is ensured. Conclusions Mold-based HDR brachytherapy seems ideally suited for UGCs.
