Q) What is the most suitable treatment option for non muscle-invasive bladder cancer with the risk of recurrences?

A)Cystectomy

B)Intravesical chemotherapy

C)Transurethral resection and adjuvant intravesical chemotherapy

D)Palliative therapy

Answer-C(Schwartz-1654)

Patients with non–muscle-invasive bladder cancer (confined to the bladder mucosa or submucosa) can be managed with transurethral resection alone and adjuvant intravesical (instilled into the bladder) chemotherapy/immunotherapy.

The use of these intravesical agents is critical since patients with non–muscle-invasive bladder cancer are at risk for tumour recurrence and progression.
