Treatment (Sacituzumab Govitecan)
Patients receive sacituzumab govitecan IV over 3 hours on days 1 and 8 of each cycle. Treatment repeats every 21 days for 3 cycles in the absence of disease progression or unacceptable toxicity. Within 2-6 weeks after last dose, patients undergo radical cystectomy and pelvic lymph node dissection. Lymphadenectomy: Undergo pelvic lymph node dissection Radical Cystectomy: Undergo radical cystectomy Sacituzumab Govitecan: Given IV
