VAI chemo is used to treat Ewings sarcoma. 

which drugs?


The drugs that are used are:

Vincristine, Actinomycin D and Ifosfamide

how is it given?

Into a vein (intravenously). This is usually through a PICC or central line.

You'll be given anti-sickness medicine as a tablet or by a drip (infusion) into your central line or PICC line. The chemo drugs are then given separately:

  • Vincristine (a clear fluid) is given as a short infusion
  • Actinomycin D (a yellow fluid) is given as a short infusion.
  • Ifosfamide (a clear fluid) is given as an infusion.

 how often will I have it?

Each cycle of treatment lasts 3 weeks (21 days)

  • Day 1: vincristine, actinomycin D, ifosfamide
  • Day 2: actinomycin D, ifosfamide and mesna
  • Day 3: actinomycin D, ifosfamide and mesna
  • Day 4-21: you'll have no chemo during this time to give your body a chance to recover
  • Day 1 of the next cycle starts the following day (day 22)


You’ll have a blood test and be seen by your doctor before each cycle of chemo.

 


Are there any side effects?

 

Some people only get a few side effects while others will have more. It’s hard to know how it will be for you. Most side effects will disappear after treatment has finished. You can read some ways to help cope with them in our deal with it section.
 

Common side effects

  • Lowered resistance to infection: Your immune system doesn’t work so well when you’re having chemo, so you might pick up more colds and infections. This begins around 7 days after treatment is started and reaches its lowest point around 10–14 days after chemo. Your blood cells then gradually go back to normal.

Keep an eye on your temperature and if it goes above 38°C (or you feel unwell) it’s important to let your doctor know. If necessary, be given antibiotics to keep any infection under control. 

  • Bruising and bleeding: The number of platelets in your blood can fall because of the chemo. This can cause bleeding or bruising (for example, of the gums, nose bleeds, heavy periods or pin prick dots on the skin). Let your doctor know if you have any problems with this. If your platelets are really low, they might suggest a platelet transfusion.
  • Anaemia: The number of red cells (haemoglobin) in your blood can be low because of the chemo. This can make you feel tired and sometimes breathless. If necessary (to help with the symptoms) your doctor might suggest a blood transfusion to increase the amount of red cells in your blood.
  • Hair loss: This usually starts 3–4 weeks after the first course of treatment. Usually all the hair on your head will fall out. You may also notice that some or all of your eyelashes, eyebrows and body hair fall out. This can feel really tough to cope with but remember that it’s temporary and your hair will start to grow again once the treatment is finished.

  • Feeling sick: Anti sickness drugs are given to help prevent or control this. Let your doctor know if you feel sick and they’ll prescribe extra medicines.
  • Bladder irritation: Ifosfamide can irritate your bladder. It's important to try to drink plenty of fluids to prevent or reduce this. You'll be given a drug called Mesna along with ifosfamide to protect your kidneys and bladder. You'll be asked to give samples of your urine so it can be tested while you're having ifosfamide.
  • Sore mouth: You might get a sore, dry mouth or notice some small ulcers. Drinking plenty of fluids and brushing your teeth regularly with a soft toothbrush can help. Doctors can prescribe mouthwashes and medicine to prevent or clear any infection.
  • Off your food: You might find that you go off certain foods or don’t have much appetite. If this happens, a dietician at the hospital can give you help and advice on what to eat and how to deal with it.
  • Tiredness: You may feel more tired than normal and might not have as much energy. It’s important to try to get as much rest as possible and take it easy. 
  • Changes to your bowels: Some of the chemo drugs can affect your bowels. If you find that you’re not going to the toilet as often as you used to, let your doctors know and they may give you some medicine to treat the constipation. If you have diarrhoea lasting longer than 2 days, let your doctor know. They may give you some medicine to treat it.
  • Numbness or tingling in your hands or feet: This is caused by the effect of vincristine on the nerves and is known as peripheral neuropathy. This usually improves slowly a few months after treatment is finished. Changes in your nails: Your nails may become darker or ridged. They usually return to normal within a few months of finishing treatment.

 

Less common side effects

  • Changes to how your liver works: This is unlikely to cause you any harm and your liver goes back to normal once treatment is finished. Your doctor will check your blood from time to time to keep an eye on how well your liver is working.
  • Changes to your skin: Your skin may become darker during treatment. You may also have a rash that becomes itchy. This usually returns to normal within a few months of finishing treatment.
  • Taste changes: You may find that your food tastes different. Normal taste usually comes back when the treatment has finished.
  • Confusion, sleepiness and loss of balance: This is rare but it’s important to tell your doctor straight away if you get any of these symptoms.


 
These are the most common side effects. It can feel really scary reading about all of these. It’s important to remember that most of them can be controlled and they will get better after the treatment is finished.


It might help to talk to your doctor or nurse about things if you’re worried or nervous. They are there to help. Also have a look at our share it section where you can talk to others who have been through a similar experience.

 


Anything else I should know?

 

  • Fertility: Treatment can also affect your fertility. That’s your ability to become pregnant or father a child. It’s really important to talk this over with your doctor before you start your treatment. See our information on fertility to find out more. Guys may need to consider sperm banking.
  • Contraception: You really shouldn't get pregnant or get someone pregnant while you’re having chemotherapy. It’s important to use effective contraception during chemotherapy and for a few months after. You can talk this over with your doctor or nurse for advice. 
  • Periods: For girls, your periods may stop. This is usually a temporary effect of treatment and they’ll come back after treatment has finished
  

How will I feel?


Chemo affects everyone differently, but it’s likely that you may feel a bit rough sometimes when you’re having your treatment. You might also feel emotional, depressed or irritable at times. All of these feelings are common for people having chemo.


Some people find it really helps to talk things over with someone close or a counsellor. If you want to find out more, there’s lots of information in our deal with it section.
