What is BCG Treatment?
BCG (Bacillus Calmette-Guérin) is a type of immunotherapy used to treat bladder cancer. It is a live, attenuated (weakened) form of the bacteria Mycobacterium bovis. The treatment works by stimulating the body’s immune system to fight the cancer cells. BCG is usually given as an intravesical (into the bladder) instillation of the BCG solution. This means that it is inserted directly into the bladder via a catheter.
How Long Does BCG Work For Bladder Cancer?
BCG treatment is typically recommended for six weeks and may be continued for up to one year. The response rate of BCG treatment can vary and may last up to five years, although some studies suggest that the effectiveness of BCG may last longer than five years.
Can Bladder Cancer Return After BCG?
Yes, bladder cancer can return after BCG treatment. Typically, recurrence occurs within the first two years after treatment. In some cases, the cancer can recur despite ongoing BCG treatment.
When Does BCG Treatment Fail?
BCG treatment may fail due to an inadequate immune response or an inability to eradicate the cancer cells. The failure rate of BCG treatment can vary depending on the type of bladder cancer, and it can range from 10-60%.
Does BCG Cure Bladder Cancer?
No, BCG treatment is not considered a cure for bladder cancer. However, it can be highly effective in controlling the cancer and preventing it from spreading. In some cases, BCG treatment can lead to a remission of the cancer.
