Brief Summary

Rationale: Prostate cancer is the most common cancer in men worldwide. Survival rates are high due to the typically non-aggressive nature of disease and effective treatments. Radical treatments such as surgery and radiotherapy often cause toxicity and long term side effects. Based on current available literature, the choice for primary therapy for clinically localised prostate cancer has a negative impact on cancer-specific quality of life (QOL). New interventional treatments are being developed. The investigators aim to build a multidisciplinary prostate cancer cohort which will serve as a multi-trial facility for interventional treatment studies. The Trials within Cohorts (TwiCs) design, also known as cohort multiple Randomized Controlled Trial design (cmRCT) will be conducted and as a prospective registry for assessment of long-term safety, performance and effectiveness new treatment interventions. Objective: To set up a cohort that will serve as a multi-trial platform and facilitate evaluation of new interventional treatment for prostate cancer. Study design: Observational, prospective cohort study, according to the 'Trials within Cohorts' (TwiCs) design. Study population: All patients with newly diagnosed histologically proven prostate cancer. Main study parameters/endpoints: Clinical parameters (e.g. co-morbidity, oncological history, symptoms, imaging, technical and treatment data), clinical endpoints (e.g. toxicity, and survival outcomes) and patient reported outcomes (e.g. QOL).
