While these data present intriguing insights between the expression of TROP2, DLL3 and PSMA with common genomic alterations in CRPC, it is important to note that these associations are also tightly associated with tumor phenotype (i.e., AR alterations are seen in AR + /NE- tumors, whereas RB1 loss is enriched in NEPC). Here, DLL3 is linked to neoplasm.
