The pTNM stage is one of the most important parameters in the handling of tumor patients. The pathologist plays a major role in the determination of the stage. The classifications undergo an evolution according to the state of art. The TNM system is used worldwide and allows to precise the tumor (T) and lymph node stage and the presence of distant metastasis. This system helps to stratify patient groups and determine their prognosis. In 2017, the Union for International Cancer Control (UICC) and the American Joint Committee on Cancer (AJCC) published their 8th edition. Unluckily several differences exist between both classifications. The UICC neglected to make several recommendations according to the International Society of Urological Pathology (ISUP) decisions, which organises the consensus in uropathology.
