Imaging and T Category for Prostate Cancer in the 8th Edition of the Union for International Cancer Control TNM Classification (European Urology Oncology)

The first requirement for clinical management of prostate cancer is to classify patients into prognostic groups to aid in decision-making on treatment options. Of all prognostic factors that determine outcomes after prostate cancer treatment, the anatomic extent of disease is one of the most important, but certainly not the only factor. `Stage`, in truth, means nothing more than the anatomic extent of disease. Standardisation of clinical staging allows comparison of populations and is therefore crucial in public health and epidemiology and routine clinical practice, as well as in the design of clinical trials.
