In the past 10 years evidence for the clinical relevance of variant histology in urinary bladder cancer has been increasing. This increase has resulted in new classifications of urothelial cancers by the WHO in 2016, highlighting the importance of an accurate morphological description of pathological specimens for the therapeutic management of patients with bladder cancer. The rising awareness of the importance of an accurate pathological report manifests itself in the increasing prevalence of reporting of variant histology in daily practice...

Gottfrid Sjödahl
Molecular subtypes of bladder cancer (BC) can be determined by relatively small immunohistochemistry panels both for non-muscle invasive (NMI) and muscle invasive (MI) tumors. For analysis of NMI tumors, as few as two markers are needed, although classification is dependent also on pathological grade and histological evaluation. The result is a classification into the three tumor-cell phenotypes of NMI-BC, Urothelial-like (Uro), Genomically Unstable (GU), and Basal/SCC-like. For analysis of MI tumors, 13 markers are needed...

BACKGROUND: Nowadays, the intravesical Bacillus Calmette-Guérin (BCG) instillation is the method of choice for the postsurgical treatment of high-grade nonmuscle-invasive bladder cancer , to reduce both recurrence rate and risk of progression. BCG is hypothesized to correct the immune system disequilibrium occurring during carcinogenesis, through an immunostimulation with detrimental effects for tumoral cells. Inflammation plays a crucial role in tumor progression. The deregulation of inflammasomes upon carcinogenesis underlines its importance both in physiologic and pathologic human conditions...
