Bortezomib, cyclophosphamide, and dexamethasone (VCD)

VCD is the name of a cancer drug combination and is a treatment for myeloma.

What is VCD?

VCD is the name of a combination of cancer drugs that includes:

• bortezomib (Velcade)
• cyclophosphamide
• dexamethasone

It is a treatment for myeloma.

How does VCD work?

Bortezomib is a type of cancer treatment drug called a proteasome inhibitor. Proteasomes are found in cells. They help to break down proteins that the cell doesn't need. Bortezomib blocks the proteasomes so the proteins build up inside the cell. The cell then dies. 

Cyclophosphamide is a type of chemotherapy and works by destroying quickly dividing cells, such as cancer cells.

Dexamethasone is a steroid. It works by helping to kill myeloma cells.

How do you have VCD?

You have bortezomib as an injection under the skin.

You have dexamethasone and cyclophosphamide as tablets. 

Injection under the skin

You usually have injections under the skin (subcutaneous injection) into the stomach or thigh.

You might have stinging or a dull ache for a short time after this type of injection but they don't usually hurt much. The skin in the area may go red and itchy for a while.

Taking your tablets

You should take the right dose, not more or less.

Talk to your healthcare team before you stop taking a cancer drug, or if you miss a dose.

Swallow cyclophosphamide tablets whole with plenty of water and do not chew or crush them.

Taking dexamethasone tablets in the morning after breakfast might help with difficulty sleeping (insomnia). It might also protect your stomach from irritation.

How often do you have VCD?

You have VCD as cycles of treatment. A cycle is the time between one round of treatment until the start of the next. After each round of treatment you have a break, to allow your body to recover. 

There are different ways of having VCD. Your doctor plans how much treatment you need and how often you have it depending on your individual situation.

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 VCD?

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. 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:

Numbness or tingling in fingers or toes

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

Pain in your muscles or nerves 

You might feel some pain in your muscles or bones. Speak to your doctor or nurse about what painkillers you can take to help with this.

You might also have pain in the hands and feet due to nerve damage. This is called neuralgia.

Constipation

Constipation is easier to sort out if you treat it early. Drink plenty of fluids 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 prescribe a laxative.

Diarrhoea

Contact your advice line if you have diarrhoea. For example, 2 or more extra loose bowel movements than usual each day. 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.

Lowered appetite

You might lose your appetite for various reasons while having cancer treatment. Sickness, taste changes or tiredness can put you off food and drinks.

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.

Tiredness and weakness (fatigue) during and after treatment 

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.

Breathlessness and looking pale 

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

Bruising, bleeding gums or nosebleeds

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).

Rarely you might see some blood in your sick.

Increased risk of getting an 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. 

Hair loss

You could lose some or all your hair. This includes your eyelashes, eyebrows, underarm, leg and sometimes pubic hair. Your hair will usually grow back once treatment has finished but it is likely to be softer. It may grow back a different colour or be curlier than before. 

Inflammation of the bladder 

You might feel that you have to pass urine more often than usual. And you may have a burning feeling when you do. Or you might feel that you can't wait when you need to go. This is called cystitis. 

It helps to drink plenty of fluids. Some people think that cranberry juice can help but others feel it makes the soreness worse. Research studies haven't found that it helps. 

You might find that some drinks increase the soreness, such as tea and coffee. You can experiment for yourself and see what works for you.

Don't take any over the counter medicines for cystitis without talking to your treatment team as they could be harmful.

Tell your doctor or nurse if you have soreness. They can prescribe medicines to help.

Kidney problems 

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.

Occasional side effects

These side effects happen in between 1 and 10 out of every 100 people (between 1 and 10%). You might have one or more of them. They include:

• heart problems such as a change in heart rhythm, changes to how well the heart works, fluid around the heart or enlargement of the heart
• changes of levels of chemicals in your blood due to the breakdown of tumour cells (tumour lysis syndrome) - you have regular blood tests to check for this
• hiccups
• blood clots that can be life threatening; signs are pain, redness and swelling where the clot is. Feeling breathless can be a sign of a blood clot in the lung. Contact your advice line or doctor straight away if you have any of these symptoms

What else do I need to know?

Other medicines, foods and drink

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

Your doctor may tell you not to drink alcohol while having cyclophosphamide as a tablet. Alcohol might change the way this drug works and may increase your chances of feeling or being sick (nausea and vomiting).

Pregnancy and contraception 

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. 

Loss of fertility 

You may not be able to become pregnant or get someone pregnant after treatment with these drugs. Talk to your doctor before starting treatment if you think you may want to have a baby in the future.

Men might be able to store sperm before starting treatment. And women might be able to store eggs or ovarian tissue. But these services are not available in every hospital, so you would need to ask your doctor about this.    

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.
