5. Fig. 4
Cancer-specific survival in 158 lymph node–positive patients after radical cystectomy for urothelial carcinoma of the bladder, stratified by absence or presence of perinodal lymphovascular invasion (pnLVI) in combination with pT category. Low risk: pnLVI absent and ≤pT2; intermediate risk: pnLVI present or ≥pT3; high risk: pnLVI present and ≥pT3.
LR=low risk; IR=intermediate risk; HR=high risk.
