In post-craniotomy brain cancer patients, patient positioning presents a particular challenge due to the risk of pressure on the surgical wound site. Therefore, the prone position is considered as an alternative approach to enhance the patient comfort and stability without compromising the accuracy of treatment planning and dose delivery.rnResearch Objective: This research aims to analyse the radiotherapy management procedure in post-craniotomy brain cancer patients using the Intensity-Modulated Radiation Therapy (IMRT) technique with an alternative prone positioning approach, and to evaluate the radiation dose received by the organs at risk (OARs).rnResearch Method: This research applied a descriptive qualitative method with case study approach conducted observationally using retrospective data.rnResearch Results: As the result, this research demonstrated that the implementation of IMRT in the prone position was carried out safely, with the radiation dose to organs at risk (OARs) remaining within permissible tolerance limits. The use of the prone position contributed to reducing pressure on the postoperative area while maintaining an optimal dose distribution in accordance with QUANTEC guidelines.rnConclusion: In principle, the IMRT technique using an alternative prone position does not differ from the supine position; however, the use of a prone-position cushion enhances the patient stability and comfort during radiotherapy. Dose distribution evaluation indicated that all cranial organs at risk (OARs) remained within safe tolerance limits in accordance with QUANTEC guidelines.rnrnKeywords : IMRT, Prone Position, Dose Distribution, Organs at Risk (OARs), RadiotherapyrnrnTranslated by:rnrnrnrnrnrnrnSuhendar, S.S., M.Pd.rnEnglish Lecturer
