Conclusions High-grade T1 bladder is a heterogeneous disease with an aggressive biologic behavior in the majority of patients High-grade T1 bladder is a heterogeneous disease with an aggressive biologic behavior in the majority of patients Radical cystectomy is not without risk, carrying a high amount of morbidity and mortality Radical cystectomy is not without risk, carrying a high amount of morbidity and mortality Risk stratification is imperative Risk stratification is imperative These tools exist and can help to objectify treatment decision-making (i.e, early cystectomy versus delayed cystectomy) These tools exist and can help to objectify treatment decision-making (i.e, early cystectomy versus delayed cystectomy)

Conclusions Considering the aggressive phenotype of high- grade T1 bladder cancer and the fact that many patients will have extravesical/nodal disease at the time of “early cystectomy”, is it justified to defer early definitive treatment in this group of patients when medically fit?
