Detailed Description
Nectin-4 is highly expressed in different types of cancer and is involved in various aspects of tumor proliferation, angiogenesis, metastasis, tumor recurrence, and DNA repair. Therefore, the development of nuclear medicine molecular probes targeting Nectin-4 is of great significance for improving the specificity and accuracy of Nectin-4 related cancer diagnosis.
EV (Enfortumab vedotin) is the first and only drug targeting Nectin-4 so far. By exploring the diagnostic efficacy of 124I-EV in tumors with high nectin-4 expression, it will not only provide evidence for the early diagnosis of tumors. At the same time, the Nectin-4 expression in tumors can be used to develop effective and precise treatment for patients.

Outcome Measures
Primary Outcome Measures
- SUV (Standardized Uptake Value) [2 years]
SUV is a semi-quantitative analysis index to describe the radioactive uptake of lesions, which has certain reference value for differentiating benign and malignant lesions。 The uptake of the tracer (124I-EV) in tumor lesions by measuring SUV on PET/CT.
