Abstract

Conservative management, specifically with active surveillance (AS), has emerged as the preferred approach for low-risk prostate cancer (LRPC). We evaluated the trend for conservative management (ie, no active treatment within 12mo of diagnosis) for LRPC in an Australian population-based cohort of men captured in the Prostate Cancer Outcomes Registry Victoria (PCOR-Vic). Of the 3201 men diagnosed with LRPC between January 2009 and December 2016, 60% (1928/3201) had conservative management, and 52% (1664/3201) were documented to be on AS. There was an increase in conservative management from 52% in 2009 to 73% in 2016 (p<0.001), largely attributable to an increase in AS from 33% in 2009 to 67% in 2016 (p<0.001). When stratified by age group, the increase in conservative management was more pronounced among younger patients: from 37% to 66% for men aged <60yr versus from 72% to 86% for men aged ≥70yr. In multivariable analyses, increasing age, lower prostate-specific antigen and clinical category, lower socioeconomic status, and being diagnosed in public metropolitan institutions were all independently associated with a greater likelihood of conservative management. Identification of sociodemographic and institutional variations in practice allows for targeted strategies to improve management for men with LRPC. PATIENT SUMMARY: We looked at the uptake of conservative management (no active treatment within 12 mo of diagnosis) over time in an Australian population-based cohort of men with low-risk prostate cancer. The proportion of men with low-risk prostate cancer managed conservatively increased from 52% in 2009 to 73% in 2016. The increase in the uptake of conservative management for low-risk prostate cancer in Australia is concordant with international guidelines and other international population-based studies.
