B: 70% chance of requiring cystectomy in 5 years after TUR
Answer: B: 70% chance of requiring cystectomy in 5 years after TUR 
Explanation: Transurethral Resection(TUR) alone in the management of patients with invasive bladder cancer carries a high likelihood of recurrence and progression. Considering the high likelihood of recurrence and progression, a greater than, 70%> chance of requiring cystectomy within 5 years appears to be logically correct.
