Can bladder cancer come back after BCG treatment?
BCG failure usually carries a risk of recurrence but rarely of progression. For low-grade failure, intravesical chemotherapy is a valid option. This scenario is different from that where BCG intravesical therapy is unsuccessful in high-risk T1 disease and/or CIS, where a risk of progression may sometimes reach 50%.
What is the success rate of BCG treatment for bladder cancer in 2021?
We found that 95% of patients completed adequate induction BCG, but only 37% of patients completed adequate maintenance BCG therapy. Patients with Cis had a significantly increased risk of progression compared with patients with no Cis.Mar 31, 2021
