Nectin-4 expression in the prostate is heterogeneous and context-dependent, with higher levels in benign glands within cancer-bearing prostates and lower levels with advancing tumor stage and nodal/metastatic spread. These findings provide an expression map of nectin 4 across benign and malignant prostate compartments and disease stages and may inform future exploratory enrichment strategies for nectin-4-targeted therapies.
We describe a 57-year-old man receiving EV and pembrolizumab who developed profound insulin-resistant DKA that persisted despite standard therapy. Following initiation of induction alongside continued insulin therapy, resolution of ketoacidosis occurred within 46 hours. This case illustrates a pharmacokinetic-informed approach to EV-associated refractory DKA and highlights how understanding drug metabolism may improve therapeutic outcomes when conventional therapy is insufficient.
