Abstract
Prostate cancer has the highest incidence in male population in Croatia and radiotherapy has been used as a treatment choice for decades. Volumetric modulated arc therapy (VMAT ) is a newer radiotherapy technique used at our department for the last year. In our study we performed the estimation of quality improvement achieved by VMAT radiation technique in comparison to 3D CRT for prostate bed irradiation. Conformity Index (CI) and dose delivered to organs at risk (OARs) have been observed. VMAT was superior in achieving more conformal dose. This method was also significantly better at sparing surrounding OARs, especially rectum and femoral heads.
