Integrative Analysis of 1q23.3 Copy-Number Gain in Metastatic Urothelial Carcinoma

Abstract

1q23.3 copy-number gain displayed association with poor survival in two cohorts of metastatic urothelial carcinoma. The identification of the target of this copy-number gain is ongoing, and exploration of this finding in other disease states may be useful for the early identification of patients with poor-risk urothelial carcinoma. Prospective validation of the survival association is necessary to demonstrate clinical relevance.
