ResumoMaterial and Methods: A bespoke QA programme was created for the 5 anatomical treatment sites which included spine and nodal metastasis.Prior to treatment centres were required to complete a QA process which included planning benchmark cases.Participating centres were provided with a pre-outlined planning CT.They created PTV expansions using local protocols.The centres were then required to create a plan based on a 30 Gy in 3 fraction prescription for the nodal case and a 24 Gy in 3 fractions prescription for the spine case.Both cases required a D95% of the prescription dose for the PTV coverage whilst ensuring OAR tolerances were met.All planning benchmarks were submitted and centrally analysed using VODCA 5.4 plan review software.The coverage of the PTV and CTV with the prescription dose, doses to OARs and measures of conformity were calculated.The values for the different submissions were compared to ensure plans were of suitable quality and comparable across different treatment platforms.
