High Risk Non Muscle-invasive Bladder Cancer Articles

High-risk non-muscle invasive bladder cancer is marked by frequent disease recurrences and risk of stage progression, contributing to high surveillance, treatment-related costs, and patient anxiety.

In case of high grade non-muscle invasive bladder cancer (HG-NMIBC), intravesical BCG represents the first-line treatment; despite the "gold" standard therapy, up to 50% of patients relapse, needing radical cystectomy.

Bacillus Calmette-Guerin (BCG) instillations are considered as a gold standard of therapy in high- and intermediate-risk non-muscle-invasive bladder cancer (NMIBC). Unfortunately, up to 40% of patients might experience treatment failure and even 15% of patients initially diagnosed with NMIBC will progress to muscle-invasive disease.

High-risk non-muscle-invasive bladder cancer (HR-NMIBC) represents over 30% of all incident urothelial bladder cancers (BCs); patients are at risk of progression, and 20-30% will die from BC within 5 yr.

Vesical Imaging Reporting and Data System (VI-RADS) score is adopted to provide preoperative bladder cancer (BCa) staging. Repeated transurethral resection of bladder tumor (Re-TURBT) is recommended in most of high-risk non-muscle-invasive bladder cancers (HR-NMIBCs) due to possibility of persistent/understaged disease after initial TURBT.

Second transurethral resection is recommended for patients diagnosed with high-risk non-muscle invasive bladder cancer; however, there have been several studies showing conflicting findings regarding the advantage of second transurethral resection.
