Current diagnostic imaging and therapies have significant limitations, highlighting the urgent need for novel theranostic targets. Nectin-4, a cell adhesion molecule frequently overexpressed in bladder cancer, especially urothelial carcinoma (∼60%-87% of tumors), has emerged as a promising biomarker and therapeutic target. This review critically evaluates the role of Nectin-4 in bladder cancer and explores its exciting potential in nuclear medicine for combined molecular imaging and targeted radionuclide therapy-embracing the \"theranostic\" paradigm. Nectin-4 is abundantly and selectively expressed in most urothelial carcinomas, correlating with advanced disease and poorer prognosis. Clinically validated by the FDA-approved antibody-drug conjugate enfortumab vedotin, Nectin-4 targeting achieves objective response rates around 40%-50% and significantly improves survival in refractory advanced urothelial carcinoma. Recent clinical advances in Nectin-4-targeted PET imaging (such as <sup>68</sup>Ga-labeled agents) have demonstrated excellent tumor localization and specificity, enabling precise patient selection for targeted therapies. Additionally, emerging radionuclide therapeutics (eg, <sup>225</sup>Ac- and <sup>177</sup>Lu-based agents) show promising preclinical and early clinical efficacy, robust tumor targeting, and favorable safety profiles. Targeting Nectin-4 represents a new frontier in the management of bladder cancer, bridging the gap between precise molecular diagnostics and personalized targeted radionuclide therapy.

Both forms of radiation can reshape the tumor immune microenvironment, providing a rationale for their combination with immune checkpoint inhibitors (ICIs) to harness synergistic effects while mitigating immunosuppressive mechanisms. Outcomes of such combinations depend on radiation dose/fractionation, treatment sequencing, target selection, and the choice of immunotherapeutic/radiopharmaceutical agents. Among novel TRT strategies, fibroblast activation protein-TRT (FAP-TRT) stands out for its targeting of cancer-associated fibroblasts (CAFs), key components of the tumor stroma involved in immune evasion and therapy resistance. Unlike conventional TRTs that directly target tumor cells, FAP-TRT acts on CAFs, potentially modulating the tumor microenvironment to enhance the immunomodulatory effects of radiation. This review examines the immunological effects of radiation-via EBRT or TRT-and the rationale for combining TRT with ICIs. We highlight preclinical and clinical studies demonstrating both the synergistic potential and context-specific limitations of TRT-ICI combinations. Emphasis is placed on the emerging role of FAP-TRT in remodeling the tumor microenvironment, converting \"cold\" tumors into \"hot\" phenotypes, and enhancing immune infiltration. Preclinical models show synergy between FAP-TRT and ICIs, but challenges remain, including clarifying FAP-TRT's effects on CAF subpopulations, optimizing radiopharmaceutical design, and addressing shared issues with TRT/EBRT-ICI combinations, such as dosing, sequencing, and target selection.
