Treatment Planning and Dosymmetric Comparison of Two Different Volumetric Arc Therapy Technique

Abstract

The purpose of this study is to compare and evaluate the performance of two different volumetric modulated arc therapy techniques. In this study, 20 patients with late stage nasopharyngeal cancer were selected for comparison of the plans. All treatment plans were selected to have 3 target volumes, doses of 70/60/54 Gy, and were generated from 33 fractions with simultaneous integrated boost technique. All treatment plans were made with Elekta VMAT using the Monaco TPS and RapidArc using Eclipse TPS. Plans were compared in terms of the 95% volume of target goal, OAR, CI, HI, and MU. Significant differences were observed in all criteria. In the RapidArc, the results were slightly lower (6913,65 ± 64,80 / 5972,02 ± 89,88 / 5391,10 ± 155,83) while the Elekta VMAT yielded better results in terms of target volume doses (6813,65 ± 79, 48 / 5926,36 ± 99,34 / 5347,65 ± 69,89). CI in Elekta VMAT (0,997±0,010 / 0,989±0,020 / 0,997±0,006) and HI (0,070±0,028 / 0,210±0,022 / 0,175±0,42) is slightly better than CI (0,991±0,011 / 0,949±0,000 / 0,950±0,001) and HI (0,075±0,016 / 0,255±0,018 / 0,210±0,54) in RapidArc. The MU of RapidArc (516,59 ± 68,03) was significantly lower than the Elekta VMAT MU (1213,30 ± 131,90).
