<prompt> Treatment of Stage I Bladder carcinoma includes all exceptLocal excisionIntravesical ChemotherapyRadiotherapyBCG  <response>: Urothelial tumors that have not invaded the detrusor muscle are termed non-muscle invasive bladder cancers NMIBCs. Approximately 70 of patients who present with bladder cancer will be diagnosed with NMBIC, which includes T stages Tis carcinoma in situ, Ta, and T1 Any tumor identified in the bladder should be fully resected by TURBT. trans urethral resection of bladder tumor Single-dose intravesical chemotherapy administered within 6 hours of resection reduces recurrence of low-risk tumors, with significant impact in the setting of initial presentation of solitary low-grade papillary tumors. Intravesicular delivery of Bacillus Calmette-Guerin BCG is also used to treat and prevent the recurrence of superficial tumors. BCG is given 2 to 4 weeks after tumor resection,allowing time for re-epithelialization.
