Doses to Organs at Risk Calculated Using Plato and Oncentra Softwares in Intracavitary Brachytherapy

This is a retrospective study, the organ doses to bladder and rectum were compared between Nucletron PLATO V14.2.3 (BV) newer version software Oncentra MasterPlan V4.3 (OMP) treatment planning systems (TPS). The data of 32 intracavitary brachytherapy patients at Hospital Universiti Sains Malaysia from January 2010 June 2015 used. These sets used for catheter reconstruction both OMP TPS followed by independent verification using Excel. There no significant difference in mean organs risk (OARs) that calculated (p>0.05). percentage 66.58 ± 27.42 % 46.27 14.47 respectively. While 65.68 24.24 46.46 16.66 comparison calculation was 1.96 6.00% then became 6.37 5.17% when it with TPS. Overall, dose differences versions within range recommended Nuclear Regulatory Commission (NRC). calculations two showed good agreement could be cervical cancer.
