When you’re diagnosed with non-muscle-invasive bladder cancer, choosing between BCG immunotherapy and intravesical chemotherapy is key. At Liv Hospital, we focus on the latest treatments to help our patients get the best results.
Studies like the POTOMAC trial have shown great results. They found that using durvalumab with BCG works well for high-risk NMIBC. Knowing about these treatments is important for both patients and doctors.

Non-muscle-invasive bladder cancer (NMIBC) is a type of bladder cancer. It stays in the inner layers of the bladder. This is important because it helps decide how to treat it.
Bladder cancer is divided into two types: non-muscle-invasive and muscle-invasive. NMIBC includes Ta, T1, and carcinoma in situ (CIS) tumors. The TNM system is used to stage NMIBC, looking at the tumor size, nearby lymph nodes, and if it has spread.
Bladder cancer is the sixth most common cancer in the U.S. NMIBC makes up a big part of new cases. “Bladder cancer is a complex disease that needs a detailed treatment plan,” says a well-known urologist.
NMIBC is more common in men and gets more common with age. Smoking, certain work chemicals, and bladder irritation or infections increase the risk. “Smoking is the biggest risk factor for bladder cancer, causing about half of all cases,”
The usual treatment for NMIBC combines surgery and intravesical therapy. TURBT is a surgery to remove tumors. Intravesical therapy puts medicine directly in the bladder to stop the cancer from coming back.
Learning about intravesical therapies, like BCG bladder cancer treatment and chemo wash, is key. Knowing about NMIBC and its treatments helps us understand how these therapies work. This knowledge is important for managing NMIBC.

Intravesical therapies are a key treatment for bladder cancer. They put medicine right into the bladder. This method helps the treatment work better and causes fewer side effects.
Intravesical treatment means putting medicine into the bladder through a catheter. It’s mainly for non-muscle-invasive bladder cancer (NMIBC). The goal is to kill cancer cells or boost the immune system to fight cancer.
This method targets the bladder directly. It helps avoid side effects seen in other treatments. It’s great for NMIBC patients because it keeps the bladder working well and improves quality of life.
There are two main types of intravesical therapies for bladder cancer: BCG immunotherapy and intravesical chemotherapy.
Choosing the right intravesical therapy depends on several things. These include the cancer’s stage and grade, the patient’s health, and past treatments.
Important factors include:
Healthcare providers look at these factors to pick the best treatment. This helps get the best results and reduces side effects.
BCG immunotherapy has changed how we treat non-muscle-invasive bladder cancer (NMIBC). It has been used for decades and works well to lower the chance of cancer coming back or getting worse in NMIBC patients.
The story of BCG immunotherapy in treating bladder cancer started in the 1970s. He noticed that BCG vaccination could boost the immune system to fight cancer. Today, BCG is key in fighting NMIBC because it sparks a strong immune response in the bladder.
Research has shown that BCG treatment can greatly lower the risk of bladder tumors coming back and stop the disease from getting worse.
BCG works by turning on the immune system in the bladder. When BCG is put into the bladder, it sticks to the bladder wall and gets noticed by immune cells. This starts a chain of immune actions, including the activation of macrophages, natural killer cells, and T lymphocytes.
These immune cells team up to kill cancer cells in the bladder. The immune response from BCG not only attacks existing cancer cells but also makes it hard for new ones to grow. This is why BCG immunotherapy helps lower the risk of cancer coming back or getting worse in NMIBC patients.
The success of BCG in treating bladder cancer is clear. Studies and real-world data show it works well for NMIBC. Knowing how BCG boosts the immune system helps doctors use it better to help patients get better.
Learning about the BCG instillation procedure can ease worries for those getting bladder cancer treatment. We’ll walk you through the steps, from getting ready to aftercare. This way, you’ll know what to expect.
Before starting, we make sure you’re ready. We review your medical history and talk about your current meds or supplements. It’s key to tell your doctor about any urinary issues or other health problems.
We also tell patients to:
The BCG process starts with a catheter in the bladder through the urethra. Then, we put in the BCG solution.
Here’s what happens during the procedure:

After the treatment, we give you care tips for a smooth recovery. This includes:
BCG is given weekly for six weeks. We’ll check on you and adjust the treatment as needed.
BCG treatment plans are made to help bladder cancer patients get better. It’s important to know these plans well for the best results.
The first part of BCG treatment is called the induction phase. It involves putting BCG into the bladder once a week for 6 weeks. This is to get rid of cancer cells in the bladder.
Key considerations during the induction phase include:
For patients at high risk, BCG treatment is needed to stop cancer from coming back. The usual plan for maintenance BCG is:
| Maintenance Schedule | Frequency | Duration |
|---|---|---|
| First maintenance cycle | Once a week for 3 weeks | 3 months after induction |
| Subsequent cycles | Once a week for 3 weeks | Every 6 months for 3 years |
How long and how often BCG treatment is needed can change. It depends on how well the patient responds and their risk factors. Important factors include:
Following the right BCG treatment plans and schedules helps doctors get the best results for patients. It also helps lower the chance of cancer coming back.
Intravesical chemotherapy is a key treatment for non-muscle-invasive bladder cancer (NMIBC). It’s an alternative to BCG therapy. This method involves putting chemotherapy directly into the bladder to fight cancer cells.
Several chemotherapy agents are used for intravesical treatment of NMIBC. Mitomycin C is often chosen because it works well to lower recurrence rates. Other agents like doxorubicin and epirubicin are also used, but their choice depends on the patient and the doctor’s preference.
Putting chemotherapy in the bladder right after surgery can help prevent cancer from coming back. This is called a “chemo wash.” Mitomycin C is often used because it’s very effective.
Some patients need more than one treatment. They might get a series of chemotherapy instillations, usually once a week for a few weeks. The exact plan depends on the chemotherapy, how well the patient can handle it, and how they respond.
Intravesical chemotherapy is a valuable option for NMIBC patients. It offers an alternative or addition to BCG therapy. By knowing the different aspects of intravesical chemotherapy, doctors can create treatment plans that fit each patient’s needs.
When treating non-muscle-invasive bladder cancer (NMIBC), BCG and chemo wash are top choices. The right pick depends on how well they stop cancer from coming back and growing.
BCG is often better than chemo wash at stopping cancer from coming back. BCG works by boosting the body’s immune system to fight bladder cancer cells. Chemo wash also helps but might not work as well for high-risk patients.
BCG and chemo wash also affect how cancer progresses. Studies show BCG lowers the risk of cancer getting worse in NMIBC patients more than chemo wash. This is key for those at high risk of cancer getting worse.
Choosing between BCG and chemo wash also depends on the patient. For example, those with high-risk NMIBC or failed chemo might do better with BCG. But, patients with health issues or can’t handle BCG might prefer chemo wash.
Choosing between BCG and chemo wash should match the patient’s needs. Healthcare providers should use the latest research to make the best choice for each patient.
Managing side effects from intravesical therapy is key for patients with bladder cancer. Treatments like BCG and chemo wash are effective but can cause side effects. It’s important to manage these to get the best results.
BCG therapy can cause side effects, from mild to severe. Symptoms include painful urination, frequent urination, and urgency. “The most common side effect of BCG therapy is cystitis, or inflammation of the bladder,” say urologists.
To ease these symptoms, patients are told to drink lots of water. They might also get medication to help with discomfort.
Some people may feel flu-like symptoms, such as fever, chills, and fatigue after BCG. These symptoms are usually short-lived and can be treated with over-the-counter drugs.
Intravesical chemotherapy, or chemo wash, also has side effects. Issues include bladder irritation, hematuria (blood in the urine), and urinary tract infections. To lessen these effects, staying hydrated is key. Healthcare providers may give specific advice to avoid complications.
Some chemotherapy agents can cause local irritation. Patients might be told how to manage this with good hygiene and possibly medication.
While many side effects can be handled at home, some need medical help. Seek immediate care for severe symptoms like high fever, intense pain, or significant bleeding. Knowing when to seek medical help is important to avoid serious issues.
Healthcare professionals stress the importance of reporting severe or persistent side effects. This is key for effective management and preventing long-term damage.
When looking at bladder cancer treatments, knowing the limits of BCG and intravesical chemotherapy is key. Some patients can’t use these treatments due to health issues. Finding out who can’t use them helps find better options.
BCG therapy is usually safe, but there are times it’s not right. Those with bleeding in the urine or who have had a traumatic catheter insertion should not get BCG. Also, people with weakened immune systems, like those with HIV/AIDS, face higher risks.
BCG is also not for those with a past tuberculosis infection. Pregnant or breastfeeding women should also avoid it, as it might harm the baby.
Intravesical chemotherapy is another good option for bladder cancer. But, it’s not for everyone. Those allergic to the chemotherapy should not get it. People with low blood cells are also at risk.
Also, those with a hole in the bladder or who have had a recent bladder surgery with bleeding should wait. This is to avoid more problems.
For those who can’t use BCG or intravesical chemotherapy, there are other choices. Radical cystectomy might be an option for some, but it’s a big surgery. It means a long recovery time.
We also look at other treatments or clinical trials. The right choice depends on the patient’s health, cancer type, and other factors.
Doctors must carefully look at each patient’s situation. They need to find the best treatment that works well and is safe.
The BCG shortage is a big problem in treating bladder cancer. It has made it hard for patients to get this important treatment.
The shortage has changed how doctors treat bladder cancer. The BCG vaccine is key for treating non-muscle-invasive bladder cancer (NMIBC). But, it’s hard to find, so doctors are looking for other options.
The BCG shortage has caused delays in treatment. Doctors are now thinking differently about how to treat patients. This has meant that some patients have had to wait for their treatments.
Impact on Patient Care
Doctors are looking at other treatments because of the BCG shortage. One option is using chemotherapy directly into the bladder, known as a “chemo wash.”
Intravesical Chemotherapy as an Alternative
Manufacturers are working hard to make more BCG. Governments are also making it easier to get BCG approved and available.
Future Outlook
We need to keep a close eye on this situation. The medical community is working together to find ways to help patients. This includes changing treatment plans as needed.
Intravesical therapies have changed how we treat non-muscle-invasive bladder cancer (NMIBC). BCG and chemo wash treatments have shown great promise. They help lower the chance of cancer coming back and improve how patients feel.
Research is always moving forward to make these treatments even better. New ways to deliver drugs and mix different treatments are being explored. This makes the future of treating bladder cancer look bright.
Choosing the right treatment for bladder cancer depends on many things. It’s important to think about the patient’s health and the cancer’s details. This helps doctors pick the best treatment, like BCG, chemo wash, or a mix of them.
We are all about giving top-notch healthcare to everyone, including international patients. As new treatments come along, we’re ready to offer the latest and best care. Our goal is to give our patients the best chance at a good outcome.
Intravesical therapy is a treatment for bladder cancer. It involves putting medication directly into the bladder. This method helps the drug reach the cancer cells in the bladder lining without harming the rest of the body.
BCG bladder cancer treatment uses a weakened form of tuberculosis bacteria. It’s given directly into the bladder. This treatment helps the body’s immune system fight bladder cancer cells.
To perform BCG instillation, a catheter is inserted into the bladder. Then, the BCG solution is administered. After that, the catheter is removed, and the solution stays in the bladder for a while before being urinated out.
Side effects of BCG treatment include frequent urination and discomfort. Some people may also experience flu-like symptoms. It’s important to know how to manage these side effects and when to seek medical help.
Chemo wash, or intravesical chemotherapy, is a treatment for bladder cancer. It involves putting chemotherapy drugs directly into the bladder. This method helps prevent cancer from coming back or getting worse.
Intravesical chemotherapy targets cancer cells with drugs. BCG treatment, on the other hand, boosts the immune system to fight cancer. The choice between these treatments depends on the cancer type and the patient’s health.
Side effects of intravesical chemotherapy include bladder irritation and frequent urination. These effects are usually manageable, and most people find the treatment tolerable.
Intravesical therapy is mainly used for non-muscle-invasive bladder cancer (NMIBC). Whether this treatment is suitable depends on the cancer’s stage, grade, and other factors, as well as the patient’s overall health.
Missing a treatment session can affect how well the therapy works. It’s important to stick to the treatment schedule. If you miss a session, talk to your doctor about what to do next.
Yes, there are other treatments available if you can’t have BCG or intravesical chemotherapy. These might include different immunotherapies, chemotherapy options, or local treatments. The right alternative depends on your specific situation and medical history.
The global BCG shortage makes treating non-muscle-invasive bladder cancer harder. Doctors might use other treatments instead. Efforts are being made to increase BCG production and get it to where it’s needed.
