(UroToday.com) There have been several recent single-arm trials in the Bacillus Calmette-Guerin (BCG) unresponsive non-muscle invasive bladder cancer (NMIBC) setting (Table 1).
The first question that arises is whether these single-arm trials are enough or do we need to randomize patients for our future trials. As seen in Table 1, these treatments are given for a minimum of two years, requiring a high number of physician visits during these treatment years. To get more accurate information, we may need to consider randomizing these patients in the long run and compare these treatments head to head before making any informed decisions.
