MVAC

MVAC is the name of a chemotherapy combination that includes: 

• M - methotrexate
• V - vinblastine
• A - doxorubicin (Adriamycin)
• C - cisplatin

It is a treatment for bladder cancer. You might have MVAC:

• to try to stop bladder cancer from coming back after surgery. This is called adjuvant therapy
• before surgery or radiotherapy to shrink the cancer. This is known as neoadjuvant therapy
• for bladder cancer that has spread to other parts of the body (advanced or metastatic bladder cancer) 

How does MVAC work?

These chemotherapy drugs destroy quickly dividing cells, such as cancer cells.

How do you have MVAC?

You have all drugs into your bloodstream (intravenously). 

Into your bloodstream

You might have treatment through a long plastic tube that goes into a large vein in your chest. The tube stays in place throughout the course of treatment. This can be a:

• central line
• PICC line
• portacath

If you don't have a central line

You might have treatment through a thin short tube (a cannula) that goes into a vein in your arm. You have a new cannula each time you have treatment.

How often do you have MVAC?

You usually have these drugs as cycles of treatment . Each cycle takes either 2 or 4 weeks. When you have MVAC over 2 weeks it is called accelerated MVAC. 

Usually, you have between 3 to 6 cycles of MVAC or accelerated MVAC.  

If you have accelerated MVAC you have methotrexate, vinblastine, doxorubicin and cisplatin on the same day.  You then have them again 2 weeks later.

After chemotherapy you may also have a drug called GCSF . You have it as injections under the skin. GCSF encourages the bone marrow (where the blood cells are made) to make more white blood cells. 

If you have it over 4 weeks (standard MVAC) you have each cycle in the following way:

Then you start a new cycle of treatment. 

Tests

You have blood tests before and during your treatment. They check your levels of blood cells and other substances in the blood. They also check how well your liver and kidneys are working.

What are the side effects of MVAC?

Side effects can vary from person to person. They also depend on what other treatments you're having. 

When to contact your team

Your doctor, nurse or pharmacist will go through the possible side effects. They will monitor you during treatment and check how you are at your appointments. Contact your advice line as soon as possible if:

• you have severe side effects 

• your side effects aren’t getting any better

• your side effects are getting worse

Early treatment can help manage side effects better. 

We haven't listed all the side effects here. Talk to your healthcare team if you have any new symptoms that you think might be a side effect of your treatment.

Remember it is very unlikely that you will have all of these side effects. But you might have some of them at the same time.

Common side effects

These side effects happen in more than 10 in 100 people (more than 10%). You might have one or more of them. They include:

Allergic reaction

Some people can have an allergic reaction while having this treatment. You might have some medication before to prevent this from happening. Let your nurse or doctor know straight away if any of the following happen:

a skin rash

itching

swelling of the lips, face or throat

shortness of breath

Your nurse will keep a close eye on you and act straight away if this happens.

Risk of infection

Increased risk of getting an infection is due to a drop in white blood cells. Symptoms include a change in temperature, aching muscles, headaches, feeling cold and shivery and generally unwell. You might have other symptoms depending on where the infection is.

Infections can sometimes be life threatening. You should contact your advice line urgently if you think you have an infection. 

Breathlessness

You might be breathless and look pale due to a drop in red blood cells. This is called anaemia.

Bruising and bleeding

This is due to a drop in the number of platelets in your blood. These blood cells help the blood to clot when we cut ourselves. You may have nosebleeds or bleeding gums after brushing your teeth. Or you may have lots of tiny red spots or bruises on your arms or legs (known as petechiae).

Tiredness (fatigue)

Tiredness and weakness (fatigue) can happen during and after treatment. Doing gentle exercises each day can keep your energy up. Don't push yourself, rest when you start to feel tired and ask others for help.

Hair thinning

Your hair may thin but you’re unlikely to lose all your hair. This usually starts after your first or second cycle of treatment. It is almost always temporary and your hair will grow back when you finish your treatment.

Kidney damage

To help prevent kidney damage, it is important to drink plenty of water. You might also have fluids into your vein before, during and after treatment. You have blood tests before your treatments to check how well your kidneys are working.

This can cause not being able to pass urine, passing urine frequently, pain when passing urine. It can also cause your kidneys not work very well or stop working.

Contact your doctor or the advice line if you have problems with passing urine.

Feeling or being sick 

Feeling or being sick is usually well controlled with anti sickness medicines. It might help to avoid fatty or fried foods, eat small meals and snacks and take regular sips of water. Relaxation techniques might also help.

It is important to take anti sickness medicines as prescribed even if you don’t feel sick. It is easier to prevent sickness rather than treat it once it has started.

A sore mouth 

Mouth sores and ulcers can be painful. It helps to keep your mouth and teeth clean, drink plenty of fluids and avoid acidic foods such as lemons. Chewing gum can help to keep your mouth moist. Tell your doctor or nurse if you have ulcers.

Diarrhoea 

Contact your advice line if you have diarrhoea. For example, in one day you have 2 or more loose bowel movements than usual. If you have a stoma , you might have more output than normal. Your doctor may give you anti diarrhoea medicine to take home with you after treatment.

Try to eat small meals and snacks regularly. It’s best to try to have a healthy balanced diet if you can. You don’t necessarily need to stop eating foods that contain fibre. But if your diet is normally very high in fibre, it might help to cut back on high fibre foods such as beans, nuts, seeds, dried fruit, bran and raw vegetables. 

Drink plenty to try and replace the fluid lost. Aim for 8 to 10 glasses per day.

Constipation

Constipation is easier to sort out if you treat it early. Drink plenty and eat as much fresh fruit and vegetables as you can. Try to take gentle exercise, such as walking. Tell your healthcare team if you think you are constipated. They can give you a laxative if needed.

Red or pink urine

This won't harm you. It’s due to the colour of the chemotherapy and lasts for one or two days.

Taste changes

Taste changes may make you go off certain foods and drinks. You may also find that some foods taste different from usual or that you prefer to eat spicier foods. Your taste gradually returns to normal a few weeks after your treatment finishes.

Indigestion

Contact your doctor or pharmacist if you have indigestion. They can prescribe something for it.

Weight loss

You might lose weight while having this treatment. Let your doctor or nurse know and they can recommend ways of maintaining your weight. Or they can refer you to a dietitian.

Headache

Tell your healthcare team if you keep getting headaches. They can give you painkillers to help.

Numbness and tingling in hands and feet

Numbness or tingling in your hands or feet is often temporary and can improve after you finish treatment. Tell your doctor if you're finding it difficult to walk or complete fiddly tasks such as doing up buttons.

Skin blisters

Your skin might blister. Tell your doctor or contact the advice line.

Pain or discomfort

You might have pain or discomfort in the muscles, jaw, bones or where your cancer is. Tell your doctor if you do.

High levels of uric acid in the blood

High levels of uric acid in your blood can lead to a build up of crystals in body tissues and cause inflamed joints. You have regular blood tests to check your levels. Drinking plenty of fluid helps to flush out the excess uric acid. You might also have medicines to control uric acid levels.

Liver changes

You might have liver changes that are usually mild and unlikely to cause symptoms. They usually go back to normal when treatment finishes. You have regular blood tests to check for any changes in the way your liver is working.

Lung changes

You might have changes to how well your lungs work. This can cause shortness of breath, coughing, wheezing and chest pain. You might also have a temperature. Tell your doctor or contact the advice line if you have any of these.

Low sodium levels in your blood

You might have a low level of a mineral called sodium in your blood. Depending on how low the level is it can cause you to feel tired and lacking in energy, lose your appetite, have a headache or feeling sick or being sick.

Your doctor checks the levels regularly when you have a blood test.  

Tummy (abdominal) pain

Tell your treatment team if you have this. They can check the cause and give you some medicine.

Changes to hearing

You may get ringing in your ears (tinnitus). This normally gets better on its own. You may have some hearing loss, especially with high pitched sounds. 

Tell your doctor or nurse if you notice any changes.

What else do I need to know?

Other medicines, foods and drinks

Cancer drugs can interact with some other medicines and herbal products. Tell your doctor or pharmacist about any medicines you are taking. This includes vitamins, herbal supplements and over the counter remedies.

Alcohol

Methotrexate contains small amounts of alcohol. This is not harmful to most people but may be if you have alcohol problems.

Loss of fertility

This treatment may harm a baby developing in the womb. It is important not to become pregnant or get someone pregnant while you're having treatment and for at least 6 months afterwards.

Talk to your doctor or nurse about effective contraception before starting treatment. Let them know straight away if you or your partner become pregnant while having treatment. 

Contraception and pregnancy

This treatment might harm a baby developing in the womb. It is important not to become pregnant or get someone pregnant while you're having treatment and for a few months afterwards.

Talk to your doctor or nurse about effective contraception before starting treatment. Let them know straight away if you or your partner become pregnant while having treatment.

Breastfeeding

Don’t breastfeed during this treatment. This is because the drugs may come through in your breast milk.

Treatment for other conditions

If you are having tests or treatment for anything else, always mention your cancer treatment. For example, if you are visiting your dentist.

Immunisations

Don’t have immunisations with live vaccines while you’re having treatment and for up to 12 months afterwards. The length of time depends on the treatment you are having. Ask your doctor or pharmacist how long you should avoid live vaccinations.

In the UK, live vaccines include rubella, mumps, measles, BCG, yellow fever and one of the shingles vaccines called Zostavax.

You can have:

• other vaccines, but they might not give you as much protection as usual
• the flu vaccine (as an injection)
• the coronavirus (COVID-19) vaccine - talk to your doctor or pharmacist about the best time to have it in relation to your cancer treatment

Members of your household who are aged 5 years or over are also able to have the COVID-19 vaccine. This is to help lower your risk of getting COVID-19 while having cancer treatment and until your immune system recovers from treatment.

Contact with others who have had immunisations - You can be in contact with other people who have had live vaccines as injections. Avoid close contact with people who have recently had live vaccines taken by mouth (oral vaccines) such as the oral typhoid vaccine. Sometimes people who have had the live shingles vaccine can get a shingles type rash. If this happens they should keep the area covered.

If your immune system is severely weakened, you should avoid contact with children who have had the flu vaccine as a nasal spray as this is a live vaccine. This is for 2 weeks following their vaccination.

Babies have the live rotavirus vaccine. The virus is in the baby’s poo for about 2 weeks and could make you ill if your immunity is low. Get someone else to change their nappies during this time if you can. If this isn't possible, wash your hands well after changing their nappy.
