Active surveillance for low-risk prostate cancer in Austria: the online registry of the Qualitätspartnerschaft Urologie (QuapU).

Abstract

Active surveillance (AS) is a well-recognized strategy to reduce the risk of overtreatment in men with low-risk prostate cancer. No data on this approach are available from Austria. The Qualitätspartnerschaft Urologie (QuapU) developed an online database for patients managed with AS in Austria. Principal inclusion/exclusion criteria corresponded to those of the S3 prostate cancer guideline of German urologists: prostate-specific antigen (PSA) <10 ng/ml, Gleason score <7 (maximum 20% of biopsies being positive). Control visits were scheduled at 3‑month intervals, control biopsies were scheduled at 12 and 36months. To date 131 patients have been entered into this data base. Mean patient age is 64years, 6% were younger than 50years, two thirds of patients were aged 50-70years and 25% were older than 70years. Mean PSA value was 5.9 ng/ml (PSA 0-4 ng/ml: 15%; PSA >4-10 ng/ml: 85%). The prostate volume averaged 39 ml. The mean time under AS was 17.5months (<12months: 60%; >12months: 40%). The AS adherence at 12months was 85% and at 24months 76%. To date, a total of 23patients (17.6%) stopped AS. The most frequent reasons for discontinuing AS were patient wish for active treatment (43.5%) and PSA progression (30.4%). A histological progression was rarely seen (6.1%) and the control biopsy rate was low (19.8%). This study is the first description of AS in Austria and documents the feasibility of an online registry for AS. The data confirm the international experience with this approach with acceptable adherence rates.
