Feasibility of 3D printing for customized radiotherapeutic models to be used in superficial skin cancer therapy

Abstract

Skin brachytherapy is an effective treatment for patients with skin cancers. It is based upon the use of an applicator containing a gamma-emitting source located near the tumor. For superficial and shallow skin tumors close to sensitive structures, we propose a new brachytherapy method using 3D printing technology employing beta-emitting isotopes. The beta-emitting patches would allow for directed, effective and controlled dose delivery to the skin tumors, thus mitigating exposure to sensitive structures.
