The 2016 WHO Classification of Tumours of the Urinary System

FIG. 18:  This work from Israel and Canada[12] examined 100 cases with variant histology diagnosed between 1995 and 2013, of which 41 were confirmed as NMI bladder cancer and treated with intravesical bacillus Calmette-Guérin (BCG). Recurrence-free survival and progression-free survival were significantly worse in the patients with variant histology tumors compared with patients with conventional disease treated with BCG (Figure).
