Subepithelial growth patterns in urothelial carcinoma-frequency and prognostic significance

Subepithelial growth is not an uncommon in bladder cancer. It is more frequent in high-grade and high-stage tumors. The findings of this study suggest that subepithelial growth carries a higher risk for stage progression (EGP and VBNI) and mortality (EGP), but not tumor recurrence.
