NECTIN4 Amplification Is a Frequent Event in Central Nervous System Metastases of Urothelial Carcinoma

We found that tumor samples from patients with cancer of the urinary tract that had spread to the brain had higher expression of a gene called NECTIN4 (67%). Our findings suggest that treatments targeting NECTIN4, such as a drug called enfortumab vedotin with or without pembrolizumab, might benefit patients with brain metastases, especially if their tumors have high NECTIN4 levels.
