Bladder cancer is the tenth most common cancer worldwide, with urothelial carcinoma accounting for approximately 90% of cases. Molecular subtypes (luminal vs. basal-squamous) predict differential responses to chemotherapy and immunotherapy. Treatment has been transformed by immune checkpoint inhibitors, antibody-drug conjugates (enfortumab vedotin targeting Nectin-4), and FGFR inhibitors (erdafitinib) for FGFR2/3-altered tumors.

Nectin-4 (PVRL4) — Nectin-4 is an adhesion molecule highly expressed on urothelial carcinoma cells and the target for enfortumab vedotin (ADC). Anti-Nectin-4 antibodies enable IHC expression profiling, ADC internalization studies, and patient stratification in urothelial cancer treatment research.

FGFR3 — FGFR3 activating mutations and fusions occur in approximately 15–20% of advanced urothelial carcinoma and predict sensitivity to erdafitinib. Anti-FGFR3 antibodies support IHC expression analysis, mutation-associated overexpression detection, and FGFR signaling pathway studies.

PD-L1 (CD274) — PD-L1 expression guides immunotherapy selection in urothelial carcinoma, with different scoring algorithms (IC for atezolizumab, CPS for pembrolizumab). Anti-PD-L1 antibodies support expression scoring validation and combination immunotherapy optimization research.
