INTRODUCTION: Describe the pattern of using advanced radiation therapy (RT) techniques, including intensity modulated RT (IMRT), volumetric modulated arc therapy (VMAT), and stereotactic body RT (SBRT) for the management of load of bone metastases (BM), and factors associated with Victoria.

METHODS: We used a population-based cohort of patients from the statewide Victorian Radiotherapy Minimum Data Set (VRMDS) who received RT for BM between 2012 and 2017. The primary outcome was the proportion RT courses using advanced RT techniques. The Cochran-Armitage trend test was used to assess the temporal trend of advanced RT use. Multinomial logistic regression was used to identify factors associated with advanced RT use.

RESULTS: A total of 18,158 RT courses were provided to 10,956 patients: 16,626 (91.6%) courses were 3D conformal RT courses, 857 (4.7%) IMRT/VMAT and 675 (3. 7%) SBRT. There was a large increase in the use of IMRT/VMAT from

CONCLUSION: Overall, there was an increasing trend in the use of advanced RT techniques for BM in Victoria, with a distinct pattern for IMRT/VMAT compared to SBRT – the adoption of SBRT was more gradual while adoption of IMRT/VMAT was steep, occurring simultaneously with Medicare Benefit Plan funding changes in 2016.
