What drugs are used to treat bladder cancer?
At this time, these drugs are used to treat bladder cancers that have spread to other parts of the body (stage IV). Atezolizumab (Tecentriq®) , durvalumab (Imfinzi®), and avelumab (Bavencio®) are drugs that target PD-L1, a protein on cells (including some cancer cells) that helps keep the immune system from attacking them.
What is the best immunotherapy for bladder cancer?
Bacillus Calmette-Guerin therapy: Bacillus Calmette-Guerin (BCG) is the main intravesical immunotherapy for treating early-stage bladder cancer. BCG is a germ that is related to the one that causes tuberculosis (TB), but it doesn’t usually cause serious disease. BCG is put directly into the bladder through a catheter.
What is non-invasive bladder cancer treatment?
The goal is to kill any cancer cells that may be left in the bladder. These cancers are only in the lining of the bladder. They may be called non-invasive (stage 0), or minimally invasive (stage I) bladder cancers. They have not spread into deeper layers on the bladder wall muscles or to other parts of the body.
Why intravesical chemotherapy for bladder cancer?
They have not spread into deeper layers on the bladder wall muscles or to other parts of the body. Intravesical chemotherapy is used for these early-stage cancers because drugs given this way mainly affect the cells lining the inside of the bladder. They have little to no effect on cells elsewhere.
What do they inject for bladder cancer?
Bacillus Calmette-Guerin (BCG) Treatment. With BCG treatment, your healthcare provider delivers immunotherapy drugs directly to your bladder through a catheter. Unlike oral or injectable drugs, BCG treatment targets cancer cells inside of your bladder without having a negative impact on the rest of your body.
What are the side effects of BCG for bladder cancer?
Common side effects of BCG include needing to urinate more often; burning or pain when urinating; blood in the urine; a mild fever; and tiredness. These side effects usually last a couple of days after each BCG treatment session. Less often, the BCG may spread through the body and can affect any organ.
What happens after BCG treatment for bladder cancer?
You may not notice any reaction after the first few BCG treatments. After the third treatment, patients usually start to experience bladder irritation pain or burning during urination, joint pain, fatigue, and flu-like symptoms that can last a few days.
How long does BCG bladder treatment stay in your system?
It may start within a few hours after getting this drug and may last for 1 to 3 days. You may pass urine more often or feel the need to pass urine right away. Call your doctor if you have bladder irritation that bothers you or does not go away within 3 days.
How toxic is BCG?
BCG has a cumulative effect, so increased toxicity is to be expected during long-term administration. BCG toxicity is primarily a response of the cell-mediated immune system, and transient local or systemic infection appears to be important.
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.
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.

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 cause hair loss?
Hair loss does not occur with BCG.
What are the complications of BCG treatment?

Jennifer Welsh is a Connecticut-based science writer and editor with over ten years of experience under her belt. She’s previously worked and written for WIRED Science, The Scientist, Discover Magazine, LiveScience, and Business Insider.
Who Can Use BCG?
BCG is a treatment for early-stage bladder cancer that has not yet invaded the muscle of the bladder wall. Called non-muscle invasive bladder cancers (NMIBCs) or in situ bladder cancers, these account for about half of all bladder cancers. 3
What to Expect During BCG Treatment
First, make sure you haven’t had any fluids for four hours before the treatment. Right before you go into the treatment room your doctor or nurse will have you empty your bladder. 2
How to Prepare
To prepare for the BCG treatment, your doctor will likely have you undergo surgery to remove any visible cancer in the bladder. The surgery is called transurethral resection of bladder tumor (TURBT) and is usually done about two weeks before BCG therapy.
When to See a Doctor
There are a few side effects that can be especially dangerous, so make sure to talk to your doctor if you notice that you: 2
Other Treatments for Bladder Cancer
For many early-stage bladder cancers, BCG is the best option for treatment. Other treatments for bladder cancer include:
Summary
BCG treatment is a form of immunotherapy for non-muscle invasive bladder cancer. It is administered into the bladder through a catheter. It then activates the body's immune system to attack the cancer cells.
How does immunotherapy work?
Immunotherapy works by encouraging a person’s immune system to attack and destroy cancer cells. Intravesical means that the treatment specifically targets the bladder. Using a catheter, a healthcare professional will administer BCG into a person’s bladder in the form of a liquid drug.
What is the treatment for bladder cancer?
Bacillus Calmette–Guerin is a form of immunotherapy that doctors can use to treat some forms of bladder cancer. Following surgery to remove the cancer, this treatment can help prevent the cancer from returning.
How long can you live with stage 1 bladder cancer?
as likely as people without it to live for at least 5 years following diagnosis. Doctors typically use BCG immunotherapy to treat stage 0 and stage 1 bladder cancer. The 5-year relative survival rate for people with stage 0 bladder cancer is 95.4 percent. Trusted Source.
How long do you have to hold your urine before you empty your bladder?
A person will then need to hold their urine for 2 hours before emptying their bladder. BCG is a type of bacterium. For several hours following the procedure, a person will need to take precautions when urinating to prevent passing the bacterium to other people.
How to keep liquid in bladder?
The healthcare professional will then either cap or remove the catheter to keep the liquid inside the bladder for a period of time. They may then ask the person to lay on their back and rotate from side to side. This movement helps the liquid reach all parts of the bladder.
What is a catheter in a urethra?
A catheter is a flexible tube that professionals can pass through the urethra into the bladder. This method of delivery allows the drug to come into direct contact with the cancer cells in the bladder. This causes the immune system to target them and not other parts of the body.
How long do you have to hold your urine for BCG?
During the treatment, a person will need to hold their urine for around 2 hours. After this, the healthcare professional will ask the individual to empty their bladder. The BCG drug contains live bacteria that a person can pass to other people.
What are the best drugs for bladder cancer?
These drugs can be used in different situations to treat bladder cancer: 1 Any of these checkpoint inhibitors can be used in people with advanced bladder cancer that starts growing again after chemotherapy. 2 Atezolizumab and pembrolizumab can be used in people who can't get the chemo drug cisplatin (due to things like hearing loss, kidney failure, or heart failure). 3 Avelumab can be used as an additional (maintenance) treatment in people with advanced bladder cancer that did not get worse during their initial chemotherapy treatments. 4 Pembrolizumab can be used to treat certain bladder cancers that are not growing into the muscle wall of the bladder, are not getting smaller with intravesical BCG, and are not being treated with a cystectomy.
What is the drug ADC?
Enfortumab vedotin (Padcev) Enfortumab vedotin is an antibody-drug conjugate (ADC), which is a monoclonal antibody linked to a chemo drug. Bladder cancer cells usually have the Nectin-4 protein on their surface. Enfortumab vedotin is an anti-Nectin-4 antibody attached to a chemo drug. The antibody part acts like a homing signal, ...
How often is pembrolizumab given?
These drugs are given as intravenous (IV) infusions, usually every 2 to 6 weeks, depending on the drug.
What drugs target PD-L1?
Atezolizumab (Tecentriq) and avelumab (Bavencio) are drugs that target PD-L1, a protein on cells (including some cancer cells) that helps keep the immune system from attacking them. By blocking PD-L1, these drugs boost the immune system's response against the cancer cells. This can shrink some tumors or slow their growth.
What antibody is used to attach to a bladder cancer cell?
In the case of this ADC, the monoclonal antibody part attaches to the Trop-2 protein on bladder cancer cells and brings the chemo directly to them. (Some bladder cancer cells have too much Trop-2, which helps them grow and spread.)
How often is PD-1 injected into IV?
This drug is infused into a vein (IV) once a week for two weeks, followed by one week off, then restarted.
What is the purpose of monoclonal antibodies?
Monoclonal antibodies. Antibodies are proteins made by your immune system to help fight infections. Man-made versions, called monoclonal antibodies, can be designed to attack a specific target, such as a protein on the surface of bladder cancer cells.
How does chemo work?
For this treatment, chemotherapy (chemo) drugs are put right into the bladder through a catheter. These drugs kill actively growing cancer cells. Many of these same drugs can also be given systemically (usually into a vein) to treat more advanced stages of bladder cancer. Intravesical chemotherapy is most often used when intravesical immunotherapy doesn't work. It's seldom used for more than 1 year.
How long does it take for a turbt to be done?
One dose of intravesical chemotherapy is done within 24 hours of TURBT. But other types of treatment are usually the next steps for Stage II to IV (2 to 4) bladder cancers because they have spread beyond the lining layer of the bladder wall.
What is the best treatment for bladder cancer?
Immunotherapy causes the body’s own immune system to attack the cancer cells. 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.
How long after a turbt can you get a tumor?
After TURBT. Intravesical therapy is commonly used after transurethral resection of bladder tumor (TURBT). It's often done within 24 hours of the TURBT procedure. Some experts say it should be done within 6 hours. The goal is to kill any cancer cells that may be left in the bladder.
What is the treatment for low grade bladder cancer?
Low-risk non-invasive (low-grade) bladder cancers grow slowly. They may be treated with 1 dose of intravesical chemo after TURBT. It's used to help keep the cancer from coming back. Intravesical chemotherapy or immunotherapy may used for intermediate non-invasive bladder cancers.
What is non invasive bladder cancer?
They may be called non-invasive (stage 0), or minimally invasive (stage I) bladder cancers. They have not spread into deeper layers on the bladder wall muscles or to other parts of the body.
How long does bladder cancer treatment last?
This is called induction therapy. After a 4- to 6-week break, maintenance treatments are then done for at least 1 year. High-risk non-invasive bladder cancers might be fast-growing (high-grade), big, or there may be more than 1 tumor.
