Identifying the Molecular Mechanisms Contributing to Progression, Metastasis, and Death in Low-grade Non–muscle-invasive Bladder Cancer: A Case Report
Transitional cell carcinoma of the bladder is a common malignancy with an estimated 549 393 new cases occurring in 2018 alone. Both non–muscle-invasive bladder cancer (NMIBC) and muscle-invasive bladder cancer (MIBC) show high recurrence and progression rates, and therefore impose a great burden on...
