Retrospective Dosimetric Comparison of HDR Interventional Radiotherapy (Brachytherapy) Versus Planning with VMAT and Electron Beam Therapy for Non-Melanoma Skin Cancer Treatment

Year: 2024

Type: article

Abstract: This study compares dosimetric outcomes of high-dose-rate (HDR) interventional radiotherapy (IRT) using Iridium-192, Volumetric Modulated Arc Therapy (VMAT), and electron beam therapy for non-melanoma skin cancer (NMSC). A retrospective analysis of 25 patients showed that IRT provided a significantly higher mean dose to the clinical target volume (CTV) compared to VMAT and electron beam therapy. IRT and VMAT had comparable V95%CTV coverage, whilst electron therapy was less feasible for large CTVs. IRT delivered higher surface doses while minimizing deep tissue exposure compared to partial arc VMAT. Our findings support IRT for personalized and effective NMSC treatment.
