What are the chances of bladder cancer returning after BCG treatment?
“Initially, it's effective,” says medical oncologist Noah Hahn, M.D. However, adds urologist Max Kates, M.D., “while up to 35 percent of patients have long-term, sustained remissions with intravesical BCG, as many as 60 percent of patients will have a recurrence of cancer within two years.Nov 2, 2020
How effective is BCG for bladder cancer?
Studies have consistently shown that BCG treatment can eradicate this cancer in 70% of patients with CIS who meet these criteria. To prevent cancer recurrence, long-term maintenance therapy following the induction phase is typically necessary.Sep 23, 2020
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
Is BCG better than chemo?
BCG is most commonly used in intravesical immunotherapy for NMIBC and appears to be more effective than intravesical chemotherapy in preventing tumor recurrence and progression. Especially for those with high-risk NMIBC, BCG immunotherapy is considered as a gold-standard treatment (29).Mar 1, 2019
What are the long term side effects of BCG treatments?

How often does BCG fail?
Evidence synthesis: Overall, the failure rate in response to BCG is about 40-50%. Most guidelines recommend that patients failing BCG should be offered radical cystectomy (RC).
Is BCG maintenance effective?
In multivariable sensitivity analyses, full-dose and one-third dose maintenance BCG was cost-effective in 17% and 39% of microsimulations, respectively. However, maintenance BCG became cost-effective if it decreased the five-year bladder cancer recurrence rate by 34.8% relative to surveillance alone.Sep 15, 2020
Is BCG a chemo or immunotherapy?
“But we need to understand how it works if we're going to make the most of this and other forms of immunotherapy.” Bacillus Calmette-Guérin (BCG) therapy is often given after surgery for early-stage bladder cancer to prevent the cancer from returning. Learn more about this treatment.Jul 17, 2020
