Summary
Brief summary
Intracavitary brachytherapy for gynaecological cancer currently use cylinder-type applicators or custom wax moulds to place a radioactive source in close proximity to the treatment area and provide highly conformal dose distributions. This study is a Phase IIa non-randomised interventional pilot trial that will investigate the feasibility of successfully treating patients with 3D-printed custom applicators.
