What type of bladder cancer is treated with BCG?
BCG treatment is used to address early-stage bladder cancer. This includes bladder cancers that haven't invaded your bladder wall muscle, such as carcinoma in situ (in its original location) bladder cancers and non-muscle invasive bladder cancers (NMIBCs).
What is success rate for BCG treatment for bladder cancer?
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.
Does BCG work for low grade bladder cancer?
Transurethral resection of bladder tumor followed by Bacillus Calmette-Guérin (BCG)—a type of intravesical immunotherapy—is the gold standard of treatment for early-stage bladder cancer, recommended by U.S. and European clinical guidelines.
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).
Why is BCG so hard to get?
Although Merck has boosted its production of BCG by more than 100 percent and is producing the drug to the fullest extent of their manufacturing capacity, they are not able to sustain the increasing global demand of this product. This has led to supply constraints and a BCG shortage.
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 are the chances of low grade bladder cancer returning?
The most important problems associated with NMIBC are that they have high rates of recurrence and risk of progression. Approximately 50% to 70% of NMIBC have a recurrence within 5 years, and 5% to 20% progress to invasive tumors [3].
How do you prevent bladder cancer from coming back?
Flushing the bladder with the chemotherapy drug gemcitabine (Gemzar) after tumors have been removed surgically may reduce the risk of the cancer returning, according to the results of a large clinical trial.
How long after Turbt can you start BCG?
BCG is given once a week for six weeks, starting 2–4 weeks after TURBT surgery. It is put directly into the bladder through a catheter. This is usually done as a day procedure in hospital, and each treatment session takes up to two hours.
Does BCG cause hair loss?
Hair loss does not occur with BCG.
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 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.
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.
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?
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.
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.
