ECarboX is a chemotherapy treatment for oesophageal and stomach cancer.
What is ECarboX?
ECarboX is the name of a chemotherapy combination that includes:
- epirubicin (Pharmorubicin)
- capecitabine (Xeloda)
It is a treatment for oesophageal (food pipe) cancer and stomach cancer.
How does ECarboX work?
These chemotherapy drugs destroy quickly dividing cells, such as cancer cells.
How do you have ECarboX?
- capecitabine as tablets that you swallow whole with plenty of water within 30 minutes of eating
- epirubicin as an injection into your bloodstream (intravenously)
- carboplatin as a drip into your bloodstream (intravenously) you can have this between 15 and 60 minutes
Into your bloodstream (intravenously)
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
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.
Taking capecitabine tablets
You must take tablets according to the instructions your doctor or pharmacist gives you.
Speak to your pharmacist if you have problems swallowing the tablets.
Whether you have a full or an empty stomach can affect how much of a drug gets into your bloodstream.
You should take the right dose, no more or less.
Talk to your healthcare team before you stop taking a cancer drug or if you miss a dose.
How often do you have ECarboX?
You have ECarboX as cycles of treatment each lasting 3 weeks. This means that you have the drug and then a rest to allow your body to recover.
Each cycle of treatment lasts around 3 weeks (21 days). You might have up to 8 cycles, taking around 6 months in total.
You have each cycle of treatment in the following way:
- You have epirubicin as an injection into your vein
- You have carboplatin as a drip into the bloodstream between 15 and 60 minutes
- You take capecitabine tablets in the morning and evening
- You take capecitabine tablets in the morning and evening
You then start the next cycle of treatment.
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.
Before starting treatment with capecitabine you have a blood test to check levels of an enzyme called dihydropyrimidine dehydrogenase (DPD). A low DPD level might mean you are more likely to have severe side effects from these drugs. So you may start treatment with a lower amount (dose) of the drug or have a different treatment. Your doctor or nurse will talk to you about this.
What are the side effects of ECarboX?
How often and how severe the side effects are can vary from person to person. They also depend on what other treatment you are having.
When to contact your team
Your doctor, pharmacist or nurse will go through the possible side effects. They will monitor you closely 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
- the side effects are affecting your daily life
Early treatment can help manage side effects better.
Contact your advice line, doctor or nurse immediately if you have signs of infection, such as a temperature above 37.5C or below 36C, or if you develop a severe skin reaction. Signs of a severe skin reaction include peeling or blistering of the skin.
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:
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.
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 on your arms or legs (known as petechiae) or general bruising, but this is less common.
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.
Feeling or being sick
Feeling or being sick is usually well controlled with anti sickness medicines. Avoiding fatty or fried foods, try eating small meals and snacks, drinking plenty of water, and relaxation techniques can all 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.
Swelling of the veins (phlebitis) and blood clots
This might start during your infusion or afterwards. Rarely, you might have a blood clot in the deep veins. Tell your doctor immediately if you have:
- pain and swelling in one of your legs, usually at the back of your leg below the knee
- warm, red skin in the affected area
- shortness of breath
- chest pain, which may be worse when breathing in
You could lose all your hair. This includes your eyelashes, eyebrows, underarms, legs 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.
You may have a burning or tingling feeling in your mouth. You may also have a dry mouth or mouth sores and ulcers that can be painful or your mouth may feel numb. But these are less common. Keep your mouth and teeth clean; drink plenty of fluids; avoid acidic foods such as oranges, lemons, and grapefruits; chew gum to keep the mouth moist and tell your doctor or nurse if you have ulcers.
Contact your advice line if you have diarrhoea, such as if you've had 4 or more loose watery poos (stools) in 24 hours. Or if you can't drink to replace the lost fluid. Or if it carries on for more than 3 days.
Your doctor may give you anti diarrhoea medicine to take home with you after treatment. Eat less fibre, avoid raw fruits, fruit juice, cereals and vegetables, and drink plenty to replace the fluid lost.
Soreness, redness and peeling on palms or soles of the feet
The skin on your hands and feet may become sore, red, or may peel. You may also have tingling, numbness, pain and dryness. This is called hand-foot syndrome or palmar plantar syndrome.
Moisturise your skin regularly. Your healthcare team will tell you what moisturiser to use.
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.
This can include pain when you pass your wee, or blood in your wee, or your wee may be a different colour. Your kidneys may stop working, but this is very rare.
Skin problems include a skin rash, dry skin and itching. This usually goes back to normal when your treatment finishes. Your healthcare team can tell you what products you can use on your skin to help.
You may get a fungal infection, but this is rare. You might have blisters or red painful skin in areas where you may have previously had radiotherapy or your skin might be sensitive to sunlight. This is also very rare.
You might have eye problems, such as inflammation of the white tissue of your eye (pink eye or conjunctivitis). Symptoms include itchy, watery or gritty eyes. Or you might have inflammation of the clear, dome shaped tissue on the front of your eye (keratitis). Symptoms include pain, blurred vision, watery eyes, and sensitivity to light. You may have double vision or loss of sight, but this is rare.
Let your doctor or nurse know if you have any problems with your eyes. They can give you eye drops to help.
Women might stop having periods (amenorrhoea) but this may be temporary.
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.
Loss of appetite and taste changes
You might lose your appetite for various reasons when you are having cancer treatment. Sickness or tiredness can put you off food and drinks. 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 goes back to normal a few weeks after your treatment finishes.
You may feel unwell if you are not eating enough. Symptoms include feeling weak or tired, or not being able to concentrate properly.
Tummy (abdominal) cramps and pain
Tell your treatment team if you have this. They can check the cause and give you medicine to help. You may also have bloating in your tummy, but this is less common.
General numbness in your body fingers and toes
You might have numbness or tingling around your body. You may notice it more in your fingers or toes. This 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.
Tell your doctor or nurse if you keep getting headaches. They can give you painkillers to help.
Fluid build up in your legs
You may have swelling of your legs due to a build up of fluid (oedema).
Your throat might get sore. It may be painful to swallow drinks or food. Ask the team looking after you if you can have painkillers to reduce the soreness. Take them half an hour before meals to make eating easier.

You might have an unusual feeling at the back of your throat (pharynx). You may have pain, but this is less common. Let your doctor know if you have any of these side effects.
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 doctor or nurse if you are constipated for more than 3 days. They can prescribe a laxative. You may also notice that you pass more wind (flatulence).
During treatment, your nails may become brittle and dry or change colour. Talk to your doctor or nurse if this happens.
Indigestion or heartburn
Contact your doctor or pharmacist if you have indigestion or heartburn. They can prescribe medicines to help.
Joint or muscle pain

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.
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.
Pregnancy and contraception
This treatment might harm a baby developing in the womb. It is important not to become pregnant or father a child while you're having treatment and for 6 months afterwards. Talk to your doctor or nurse about effective contraception before starting treatment.
Don’t breastfeed during this treatment and for 2 weeks after your final treatment. This is because the drug may come through into your breast milk.
Treatment for other conditions
Always tell other doctors, nurses, pharmacists or dentists that you’re having this treatment. For example, if you need treatment for anything else, including teeth problems.
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
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.
This drug contains lactose (milk sugar). If you have an intolerance to lactose, contact your doctor before taking this medicine.
