Between 1999 and 2009 in the United Kingdom, 82,429 men between 50 69 years of age received a prostate-specific antigen (PSA) test. Localized prostate cancer was diagnosed 2664 men. Of these men, 1643 were enrolled trial to evaluate effectiveness treatments, with 545 randomly assigned receive active monitoring, 553 undergo prostatectomy, radiotherapy.

To determine, within the UK, stage and grade of prostate cancers that would be found through population-based specific antigen (PSA) testing biopsy.In 'Prostate Testing for Cancer Treatment' trial (ProtecT), men aged 50-69 years were recruited from nine cities in UK randomly selected practices general practitioners. Those with a PSA level >3 ng/mL offered biopsy. Age, PSA, at diagnosis ProtecT participants cancer compared contemporaneous incident cases (age-restricted Registry cases)...

Background Prostate cancer is the most common among men in UK. Prostate-specific antigen testing followed by biopsy leads to overdetection, overtreatment as well undertreatment of disease. Evidence treatment effectiveness has lacked because paucity randomised controlled trials comparing conventional treatments. Objectives To evaluate treatments for localised prostate (active monitoring, radical prostatectomy and radiotherapy) aged 50–69 years. Design A prospective, multicentre...

Summary— The clinical outcome of 278 prostate cancer patients managed by a deferred treatment policy was analysed retrospectively. Following TURP or biopsy, all were asymptomatic and deemed suitable for management policy, i.e. hormone therapy other forms only initiated if when symptomatic progression occurred. overall 5‐year survival rate 30%; 18% died from causes without needing their cancer; 11% alive untreated after 5 years' follow‐up; 17% further treatment. Poor tumour grade, anaemia,...

The UK National Institute for Health and Clinical Excellence (NICE) guidance recommends conservative management of men with ‘low-risk’ localised prostate cancer, monitoring the disease using prostate-specific antigen (PSA) kinetics re-biopsy. However, there is little evidence changes in PSA level that should alert to need clinical re-assessment. This study compares alerts resulting from a novel longitudinal reference range approach, which incorporates age-related changes, during 408 cancer....
