When does maintenance start for BCG?
Maintenance BCG is typically given once per week for three weeks at 3, 6, and 12 months after the initial BCG treatment. In some cases, maintenance BCG treatment will be recommended for one year for those at intermediate risk of recurrence and for three years for those at higher risk for recurrence.
How does BCG maintenance work?
BCG treatment schedule The initial BCG cancer treatment occurs weekly for six weeks. This is called induction therapy. If the treatment is working, your doctor may prescribe BCG maintenance therapy. Maintenance therapy is given once a week for three weeks at the three-, six- and 12-month marks.
Is BCG maintenance necessary?
BCG maintenance therapy The schedule for instillations of BCG has varied from monthly to every 3 months to every 6 months. The only maintenance regimen proven to prevent recurrence and progression is the SWOG protocol, which consists of 3 weekly treatments at months 3, 6, 12, 18, 24, 30, and 36.
How long does BCG treatment last?
Maintenance treatment with BCG reduces the risk of the disease coming back or spreading. Maintenance treatment can last for 1–3 years, but treatment sessions become much less frequent (e.g. one dose a month). Treatment schedules can vary so ask your doctor for further details.
Can BCG treatment damage the bladder?
The most common complications associated with BCG treatment are relatively minor. They include urinary frequency, cystitis, fever, and hematuria. Although serious complications are rare, patients can develop severe, life-threatening sepsis with disseminated mycobacterial infection.
What is the success rate of BCG treatment?
This method of treatment is considered a form of immunotherapy, which is an emerging form of cancer treatment. The success rate for BCG treatment for bladder cancer is about 90%, which is considered the best life-saving rate by any treatment.
What are the long term side effects of BCG treatments?
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 a chemo or immunotherapy?
Bacillus Calmette-Guerin or BCG is the most common intravesical immunotherapy for treating early-stage bladder cancer. It's used to help keep the cancer from growing and to help keep it from coming back. BCG is a germ that's related to the one that causes tuberculosis (TB), but it doesn't usually cause serious disease.
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).
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 happens if BCG treatment fails?
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%.
Does BCG treatment affect the immune system?
Bacillus Calmette–Guérin (BCG) vaccination has been reported to decrease susceptibility to respiratory tract infections, an effect proposed to be mediated by the general long-term boosting of innate immune mechanisms, also termed trained immunity.
