Active surveillance of men with low risk prostate cancer: evidence from the Prostate Cancer Outcomes Registry-Victoria.

Objective: To characterise the practice of active surveillance (AS) for men with low risk prostate cancer by examining the characteristics of those who commence AS, the rate of adherence to accepted AS follow-up protocols over 2 years, and factors associated with good adherence. Design, setting: Retrospective cohort study; analysis of data collected from 38 sites participating in the Prostate Cancer Outcomes Registry-Victoria.

Participants: Men diagnosed with prostate cancer between August 2008 and December 2014 aged 75 years or less at diagnosis, managed by AS for at least 2 years, and with an ISUP grade group of 3 or less (Gleason score no worse than 4 + 3 = 7).
