3%) at 3 months, and 13 recurrences (35.1%) at 1 year. Newly presenting MIBC managed with currently available treatments has a high mortality rate of 33.3% at 1 year. The quality of TURBT in the UK is high. Areas for improvement include the timeliness of diagnosis and treatment, and improved care of patients with intermediate-risk NMIBC and MIBC. The ��snapshot�� methodology is promising but widening participation is a priority. ""A significant proportion of patients diagnosed with prostate cancer do not require immediate treatment and could be managed by active surveillance, which usually includes serial measurements of prostate-specific antigen http://www.selleck.cn/products/VX-770.html (PSA) levels and regular biopsies. The rate of rise in http://www.selleckchem.com/products/SB-431542.html PSA levels, which could be calculated as PSA velocity or PSA doubling time, was previously suggested to be associated with the biological aggressiveness of prostate cancer. Although these parameters are obvious candidates for predicting tumour progression in active surveillance patients, earlier studies that examined this topic provided conflicting results. Our analysis showed that PSA velocity and PSA doubling time calculated at different time-points, by different methods, over different intervals, and in different sub-groups of active surveillance patients provide little if any prognostic information. Although we found some significant associations between PSA velocity and the risk of progression as determined by biopsy, the actual clinical significance of this association was small. Furthermore, PSA velocity did not add to the predictive accuracy of total PSA. To study whether prostate-specific antigen (PSA) velocity (PSAV) and PSA doubling time (PSADT) are associated with biopsy progression in patients managed by active surveillance. Our inclusion criteria for active surveillance are biopsy Gleason sum http://www.selleckchem.com/products/INCB18424.html PSA kinetics and progression at successive surveillance biopsies in different sub-groups of patients by calculating the area under the curve (AUC) as well as sensitivity and specificity of different thresholds. Over a median follow-up of 3.0 years, the disease of 64 (26%) patients progressed. PSADT was not associated with biopsy progression, whereas PSAV was only weakly associated with progression in certain sub-groups. However, incorporation of PSAV in models including total PSA resulted in a moderate increase in AUC only when the entire cohort was analysed.
