Non-muscle Invasive Bladder Cancer
The majority of bladder cancer cases (75%) are classified as non-muscle invasive bladder cancer (NMIBC), which refers to cancer that is limited to the mucosa and submucosa of the bladder. Alfa Cytology offers comprehensive research services aimed at supporting the development of diagnostics and therapeutics for NMIBC, leveraging our expertise in preclinical research to expedite your breakthroughs.
Overview of Non-muscle Invasive Bladder Cancer
The category of non-muscle invasive bladder cancer encompasses papillary tumors located within the mucosa (stage Ta), tumors that invade the lamina propria (stage T1), and flat high-grade lesions known as carcinoma in situ (CIS). NMIBC is characterized by its limited invasion, rendering it less aggressive compared to muscle-invasive bladder cancer. In contrast to muscle-invasive cancer, NMIBC is primarily managed through local endoscopic/intravesical therapy and surveillance.
Definitions of high-risk non-muscle-invasive bladder cancer according to the American and European Urologic Associations.
European Urologic Association
- Carcinoma in situ
- High-grade T1 tumors
- Recurrent or multifocal or large (> 3 cm) high-grade Ta tumors
- Any tumor following BCG failure
- Lymphovascular invasion or non-urothelial histology
- High-grade tumor involving prostatic urethra
American Urological Association
- Carcinoma in situ
- Any high-grade tumor
- Any T1 tumor
- Multiple, recurrent, and large low-grade Ta tumors
Highest risk:
- T1 HG with CIS
- Multiple, large, or recurrent T1 high-grade tumors
- T1 with CIS in prostatic urethra
- Some variant histology or lymphovascular invasion
