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.

Can BCG cure bladder cancer?

BCG is type of immunotherapy for bladder cancer. Doctors typically use BCG to prevent cancer returning following TURBT in people with early-stage disease. BCG is not effective against bladder cancer that has spread to other parts of the body.

When does BCG treatment fail?

BCG refractory is when there is failure to achieve a disease-free state within 6 months after initial BCG, with either maintenance or re-treatment at 3 months because of either persistent or rapidly recurrent disease.

What are the long term effects of BCG treatment for bladder cancer?

These adverse effects include fever, malaise, and bladder irritation (urination frequency, dysuria, or mild hematuria). Fever indicates adequate immune activation and is associated with a more favorable antitumor response (25). Skin rash and arthralgia are possible allergic reactions (26,27).

What if BCG does not work?

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%.

How long does BCG treatment stay in your system?

BCG can remain in urine for 6 hours after your treatment, so each time you urinate, you should bleach the toilet in your home to neutralize the vaccine.

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).

How long does BCG last in bladder?

These can last for 2 to 3 days after treatment. It also commonly causes a burning feeling in the bladder, the need to urinate often, and even blood in the urine. Rarely, BCG can spread into the blood and through the body, leading to a serious infection.

Can BCG treatment be repeated?

In patients who develop a CIS recurrence after a single prior BCG failure, repeat BCG-based therapy should be administered. Repeat BCG monotherapy has demonstrated a 2-year disease-free rate of 30–42% in two small studies [2, 59].

Do BCG side effects get worse with each treatment?

The irritative reactions usually are seen following the third instillation and tend to increase in severity after each administration. There is no evidence that dose reduction or antituberculous drug therapy can prevent or lessen the irritative symptoms of TheraCys.

Can BCG cause hair loss?

Hair loss does not occur with BCG.

Can BCG treatment damage kidneys?

Local and systemic infection following intravesical BCG is widely reported as compared to immune mediated local or systemic hypersensitivity reactions involving kidneys; acute kidney injury (AKI) and other renal manifestations are well reported but not of chronic kidney disease (CKD).
