Grading Noninvasive Bladder Cancer: World Health Organisation 1973 or 2004 May Be the Wrong Question

Murali Varma et al. Eur Urol. 2019 Oct.

Abstract

The clinical utility of the World Health Organisation 1973 and 2004 systems for grading bladder cancer are limited by inclusion of biologically heterogeneous categories of grade 2 and high grade, respectively. Reporting both systems in parallel would improve risk stratification by splitting these categories.
