dc.description.abstractEste trabajo presenta una auditoría dosimétrica de pacientes sometidos a radiocirugía, abordando un estudio de cohorte descriptivo retrospectivo. La población de estudio consistió en pacientes con lesiones intracraneales tratados mediante técnicas HyperArc y VMAT, durante el periodo comprendido entre el 01 de enero de 2022 y el 30 de junio de 2023. La muestra total incluyó a 21 pacientes. El objetivo principal de esta investigación fue evaluar la optimización de los tratamientos de radiocirugía realizados en el Hospital Universitario del Valle. Se llevó a cabo una caracterización detallada de la muestra de estudio, seguida de un análisis individual de las variables relacionadas con la implementación del protocolo. La determinación de la dosis puntual se realizó mediante una prueba End to End, siguiendo las recomendaciones del CoP TRS-483. Asimismo, se efectuó la medición del índice gamma evaluando los diferentes criterios, la dosis de prescripción y el índice de Paddick. Además, se adaptaron y establecieron protocolos para garantizar su correcta ejecución. Los resultados de este estudio indican la implementación de protocolos actualizados en línea con las recomendaciones del TRS-483. Además, se llevó a cabo una prueba End to End para la evaluación de la cadena de tratamiento y por último se establecieron niveles de acción específicos en base a los resultados obtenidos.

dc.description.abstractThis paper presents a dosimetric audit of patients undergoing radiosurgery, addressing a retrospective descriptive cohort study. The study population consisted of patients with intracranial lesions treated by HyperArc and VMAT techniques, during the period from January 1, 2022 to June 30, 2023. The total sample included 21 patients. The main objective of this research was to evaluate the optimization of radiosurgery treatments performed at the Hospital Universitario del Valle. A detailed characterization of the study sample was carried out, followed by an individual analysis of variables related to protocol implementation. The determination of the point dose was performed by means of an End to End test, following the recommendations of the TRS-483 CoP. Likewise, the gamma index was measured by evaluating the different criteria, the prescription dose and the Paddick index. In addition, protocols were adapted and established to ensure their correct execution. The results of this study indicate the implementation of updated protocols in line with TRS-483 recommendations. In addition, an End to End test was carried out for the evaluation of the treatment chain and finally specific action levels were established based on the results obtained.eng
