Tumeur urothéliale de vessie T1 : valeur pronostique du franchissement de la muscularis mucosae (T1a/T1b). Étude multicentrique du Comité de cancérologie de l'Association française d'urologie (CCAFU)

This study, the largest on the subject to our knowledge, have shown that muscularis mucosae invasion was a prognostic factor for survival without progression, specific survival, and global survival. We support that routine pathological assessment of the level of MM invasion in patients with stage T1 bladder cancer should be included in the histopathological report.
