Results A dose of 25Gy in a single fraction is delivered to the PTV. 3 patients have been treated to date. All patients were successfully treated to the prescribed dose. All treated patients remain alive at a minimum of 6 months post treatment. 1 patient has remained free from sustained VT events since treatment 8 months ago. 2 patients have had some VT events since treatment and we continue to analyse their response. Conclusion cSABR is an innovative treatment for intractable VT. It is well tolerated and non-invasive unlike some other established treatments for this condition. Our experience shows modest success in the short term. The late effects of high doses of radiation to the heart remain unknown and in future treated patients will need close follow up in a clinical trials setting. As more patients are treated with cSABR we hope to find its place in the ongoing management of this debilitating and life threatening condition.

We present the implementation and results in our department. Materials and Methods In 2013 we implemented PR rounds on a daily basis. The reviewed cases and the decisions were recorded prospectively in Redcap database (table1). Pre-2017 the evaluation was conducted by radiation oncologists (RO) and medical physicists (MP) the day of the first fraction. The analysis is divided in two periods pre and post 2017 when there was a merge with another RO department.

Results From 2013 to 2022 a total of 11.968 cases were peer reviewed. The distribution of decisions on prescription, volume delineation (per site and volume type) is shown in Fig.1.
