how effective is bcg for bladder cancer



The success rate for BCG treatment for bladder cancer is about 90%, which is considered the best life-saving rate by any treatment.Dec 20, 2021

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.

Can bladder cancer return after BCG?

The standard of care for patients with high-grade (HG) non-muscle invasive bladder cancer (NMIBC) remains intravesical bacillus Calmette-Guérin (BCG) following transurethral resection. Unfortunately, up to 75% will develop tumor recurrence and 20% will progress within 5 years despite intravesical therapy.

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.

How many times can you have BCG treatments for bladder cancer?

BCG is in a liquid solution that is put into the bladder with a catheter. The person then holds the solution in the bladder for two hours before urinating. The treatment is usually given once per week for six weeks, starting approximately two to three weeks after the last TURBT.

What happens if BCG treatment doesn’t 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 bladder treatment stay in your system?

BCG is given directly into the bladder (called intravesicular) through a catheter. The medicine is left in the bladder for 1-2 hours. The dosage and schedule is determined by your healthcare provider. It is not uncommon to have urinary frequency (need to go often) or painful urination for 48 hours after treatment.

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].

What are the long term side effects of BCG treatment?

Commonly reported side effects of bcg include: urinary tract infection, detrusor hyperreflexia of bladder, fever, hematuria, urinary frequency, urinary urgency, vomiting, chills, and malaise. Other side effects include: arthralgia. See below for a comprehensive list of adverse effects.

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).

Does BCG treatment cause hair loss?

Hair loss does not occur with BCG.

How much does BCG bladder treatment cost?

The mean cost of BCG therapy was US$1,936 per patient, and its cost-effectiveness ratio was US$525 per recurrence-free year.
