Abstract: BACKGROUND: Docetaxel has emerged as a standard-of-care for metastatic hormone-sensitive prostate cancer (mHSPC). Uptake of docetaxel for mHSPC in Australia has not previously been reported. AIMS: i) To investigate the real-world uptake of docetaxel in mHSPC; and ii) To identify predictors of utilisation of Docetaxel in mHSPC. METHODS: Men diagnosed from June 2014 to December 2018 and enrolled in the Prostate Cancer Outcomes Registry-Victoria (PCOR-Vic) were included. Data collected includes demographics, diagnosis method and institution, staging investigations, and treatments within 12 months of diagnosis. Wilcoxon rank-sum, chi-square and trend tests were used to identify predictors of docetaxel utilisation. All predictors were entered as covariates simultaneously into a multivariable logistic regression model. Statistical significance was set at 0.05 (two-sided). RESULTS: 1014 men with mHSPC were analysed, 25% of whom received docetaxel with androgen deprivation therapy (ADT). Uptake of docetaxel increased from 20% in 2014 to 33% in 2018. Predictors of higher usage of docetaxel were younger age and treatment in a private hospital, with both remaining significant on multivariable analysis. Notably, the proportion of men under 70 receiving docetaxel increased from 54% in 2014-15 to 64% in 2016-18, while in men aged 70 and over the comparative figures were 15% and 22% respectively. CONCLUSIONS: Although docetaxel was not used in a majority of cases, there was a clear increase in docetaxel uptake especially in younger men following publication of the CHAARTED and STAMPEDE trials. Identifying barriers to real-world implementation of pivotal clinical trial data is critical to improving outcomes in mHSPC. This article is protected by copyright. All rights reserved.
