ECX
ECX is a cancer drug treatment. It is used to treat stomach cancer and oesophageal cancer.
What is ECX?
ECX is a combination of cancer drugs. It is used to treat stomach cancer and oesophageal cancer. It may sometimes be used to treat other cancers.
It is best to read this information with our general information about chemotherapy and the type of cancer you have.
ECX is named after the initials of the drugs used in the treatment. The drugs are:
- epirubicin
- cisplatin
- capecitabine (also called Xeloda®)
Your cancer team will talk to you about this treatment and its possible side effects before you agree (consent) to have treatment.
More information about this treatment
This information is correct at time of publishing. But sometimes the types of cancer this treatment is used for, or treatment side effects, may change between revision dates.
You can talk to your cancer team if you want more detailed information about this treatment. Or visit the electronic Medicines Compendium (eMC) website, which has patient information leaflets (PIL) for individual drugs.
DPD testing before treatment
Before starting this treatment, you should have a blood test to check for gene changes that affect how your body produces DPD. DPD is an enzyme that helps the body break down capecitabine.
If you have low DPD levels or no DPD (DPD deficiency), you have more risk of serious or life-threatening side effects from capecitabine. To reduce your risk, your doctor may give you:
- a lower dose of capecitabine to start with
- a different type of chemotherapy.
Having low DPD levels does not usually cause any symptoms. Without a test, you will not know whether your DPD levels are low. Testing finds most people who are affected, but not all. Your doctor, nurse or pharmacist can give you more information about your risk of DPD deficiency, before you start treatment.
How ECX is given
You usually have ECX in a chemotherapy day unit or clinic as an outpatient.
During your course of treatment, you will meet someone from your cancer team, such as a:
- cancer doctor
- chemotherapy nurse or specialist nurse
- specialist pharmacist.
This is who we mean when we mention doctor, nurse or pharmacist in this information.
Before or on the day of each treatment, you will have a blood test. This is to check that it is safe for you to have treatment.
You will meet with a doctor, nurse or pharmacist before you have treatment. They will talk to you about your blood results and ask how you have been feeling. If your blood results are okay, the pharmacy team will prepare your cancer drugs.
Your nurse will usually give you anti-sickness drugs before the cancer drugs. You will have your cancer treatment through 1 of the following:
- a cannula – a short, thin tube the nurse puts into a vein in your arm or hand
- a central line – a fine tube that goes under the skin of your chest and into a vein close by
- a PICC line – a fine tube that is put into a vein in your arm and goes up into a vein in your chest
- an implantable port (portacath) – a disc that is put under the skin on your chest or arm and goes into a vein in your chest.
Your nurse will give you the epirubicin as an injection. Epirubicin is a red colour. You will have a drip of fluids at the same time. This flushes the epirubicin through.
You will have the cisplatin as an infusion. You will have extra fluids given into your vein before and after the cisplatin. Your healthcare team may also advise you to drink plenty of fluids for a few days after the cisplatin.
Your cancer team will give you the capecitabine tablets to take at home. Always take the tablets exactly as explained. This is important to make sure they work as well as possible for you.
Your cancer team may also give you anti-sickness drugs and other medicines to take home. Take all your capsules or tablets exactly as they tell you to.
Your course of chemotherapy
You usually have a course of several cycles of treatment over a few months. Your cancer team will discuss your treatment plan with you. They may give you a copy of the plan to take home.
Each cycle of ECX takes 21 days. After the 21 days, you start another cycle of treatment. This is the same as the first cycle. For each cycle you have:
- epirubicin on day 1
- cisplatin on day 1 of each cycle
- capecitabine tablets every day, starting on day 1 in the evening
Your cancer team will tell you how many cycles of treatment you may have.
Taking your capecitabine tablets
You may be given tablets of different strengths. The dose of capecitabine may change from one cycle to the next. This may be because of side effects or changes to your weight. It is very important that you know how many tablets to take each time you start a new cycle.
You take capecitabine tablets twice a day about 12 hours apart.
Make sure you:
- take them within 30 minutes of eating a meal
- swallow them whole with a glass of water
- do not chew, break or crush them
- take them at the same times every day
Ask your doctor, nurse or pharmacist for advice if you find it difficult to swallow the tablets or if you use a feeding tube. They can give you instructions about dissolving the tablets. It is important to follow their instructions carefully.
If you forget to take the tablets, do not take the missed dose. Take the next dose as usual. Do not take a double dose. Contact the hospital on the 24-hour number you have been given for advice.
Other things to remember about your tablets:
- Wash your hands after taking them.
- Other people should avoid direct contact with them.
- Keep them in the original package and at room temperature, away from moisture, heat and direct sunlight.
- Keep them safe, where children cannot see or reach them.
- If you are sick (vomit) just after taking them, do not take an extra dose. Take your next dose at the usual time.
- Do not throw away unused capsules or tablets. Return them to your cancer team at the hospital.
About side effects
We explain the most common side effects of this treatment here. We also include some that are less common.
You may get some of the side effects we mention, but you are unlikely to get all of them. And you may have some side effects, including rarer ones, that we have not listed here.
Always tell your doctor, nurse or pharmacist about any side effects you have. They can give you:
- drugs to help control some side effects
- advice about managing side effects.
It is important to take any drugs exactly as explained. This means they will be more likely to work for you.
Serious and life-threatening side effects
Some cancer treatments can cause serious side effects. Sometimes, these may be life-threatening. Your doctor, nurse or pharmacist can explain the risk of these side effects to you.
If your body does not produce enough of an enzyme called DPD, you may have a higher risk of severe or life-threatening side effects.
Contact the hospital
Your doctor, nurse or pharmacist will give you 24-hour contact numbers for the hospital. If you feel unwell or need advice, you can call at any time of the day or night. Save these numbers in your phone or keep them somewhere safe.
Side effects while treatment is being given
Allergic reaction
Some people have an allergic reaction while having this treatment. Signs of a reaction can include:
- feeling hot or flushed
- shivering
- itching
- a skin rash
- feeling dizzy or sick
- a headache
- feeling breathless or wheezy
- swelling of your face or mouth
- pain in your back, tummy or chest.
Your nurse will check you for signs of a reaction during your treatment. If you feel unwell or have any of these signs, tell them straight away. If you do have a reaction, they can treat it quickly.
Sometimes a reaction happens a few hours after treatment. If you develop any of these signs or feel unwell after you get home, contact the hospital straight away on the 24-hour number.
Always call 999 if swelling happens suddenly or you are struggling to breathe.
The drug leaks outside the vein
Sometimes cancer drugs that are given into a vein may leak outside the vein. If this happens, some drugs can damage the tissue near the vein. This is called extravasation. Extravasation is not common, but it is important that it is dealt with quickly. If you have any of the following symptoms around the vein during or after your treatment, tell your nurse straight away:
- stinging
- pain
- swelling
- if you have white skin, the area may become red
- if you have black or brown skin, the area may become darker.
Facial flushing
While epirubicin is being given, you may suddenly feel warm. If you have white skin, your skin may get red. If you have black or brown skin, your skin colour may deepen This should only last a few minutes.
Very common side effects
Risk of infection
This treatment can reduce the number of white blood cells in your blood. These cells fight infection. If your white blood cell count is low, you may be more likely to get an infection. A low white blood cell count is called neutropenia.
An infection can be very serious when the number of white blood cells is low. It is important to get any infection treated as soon as possible. If you have any of the following symptoms, contact the hospital straight away on the 24-hour number:
- a temperature above 37.5°C
- a temperature below 36°C
- you feel unwell, even with a normal temperature
- you have symptoms of an infection.
Symptoms of an infection include:
- feeling shivery and shaking
- a sore throat
- a cough
- breathlessness
- diarrhoea
- needing to pass urine (pee) often, or discomfort when you pass urine.
It is important to follow any specific advice your cancer treatment team gives you.
Your white blood cell count will usually return to normal before your next treatment. You will have a blood test before having more treatment. If your white blood cell count is low, your doctor may delay your treatment for a short time, until your cell count increases.
Bruising and bleeding
This treatment can reduce the number of platelets in your blood. Platelets are cells that help the blood to clot.
If the number of platelets is low, you may bruise or bleed easily. You may have:
- nosebleeds
- bleeding gums
- heavy periods
- blood in your urine (pee) or stools (poo)
- tiny red, brown or purple spots that may look like a rash – these spots can be harder to see if you have black or brown skin.
If you have any unexplained bruising or bleeding, contact the hospital straight away on the 24-hour number. You may need a drip to give you extra platelets. This is called a platelet transfusion.
Anaemia (low number of red blood cells)
This treatment can reduce the number of red blood cells in your blood. Red blood cells carry oxygen around the body. If the number of red blood cells is low, this is called anaemia. You may feel:
- very low in energy
- breathless
- dizzy and light-headed.
If you have these symptoms, contact the hospital straight away on the 24-hour number. You may need treatment for anaemia. If you are very anaemic, you may need a drip to give you extra red blood cells. This is called a blood transfusion.
Feeling sick
Your doctor, nurse or pharmacist will prescribe anti-sickness drugs to help prevent or control sickness. Take the drugs exactly as they tell you to, even if you do not feel sick. It is easier to prevent sickness than to treat it after it has started.
If you feel sick, take small sips of fluid often and eat small amounts regularly. It is important to drink enough fluids. If you continue to feel sick, or if you are sick (vomit) 1 to 2 times in 24 hours, contact the hospital on the 24-hour number as soon as possible. They will give you advice. They may change your anti-sickness treatment. Let them know if you still feel sick.
Diarrhoea
Capecitabine may cause diarrhoea. Sometimes it is severe. Diarrhoea means passing more stools (poo) than is normal for you, or having watery or loose stools. If you have a stoma, it will be more active than usual. Your doctor, nurse or pharmacist may give you anti-diarrhoea drugs to take at home.
If you have diarrhoea or an increase in stoma activity, follow their advice on:
- taking the anti-diarrhoea drugs
- how much and what type of fluids to drink
- any changes to your diet that might help.
After this, contact the hospital on the 24-hour number straight away if:
- you have diarrhoea at night
- you have uncomfortable stomach cramps
- you have diarrhoea 4 or more times in a day
- you have a moderate increase in stoma activity
- the anti-diarrhoea drugs do not work within 24 hours.
They will tell you to stop taking capecitabine. When the diarrhoea is better, they will tell you whether you can start taking it again. Sometimes they reduce the dose.
Sore mouth and throat
This treatment may cause a sore mouth and throat. You may also get mouth ulcers. This can make you more likely to get a mouth or throat infection. Use a soft toothbrush to clean your teeth or dentures in the morning, at night and after meals.
Contact the hospital straight away on the 24-hour number, if:
- a sore mouth or throat affects how much you can drink or eat
- your mouth, tongue, throat or lips have any blisters, ulcers or white patches.
They can give you advice, and mouthwash or medicines to help with the pain or to treat any infection. Follow their advice and make sure you:
- drink plenty of fluids
- avoid alcohol and tobacco
- avoid food or drinks that irritate your mouth and throat.
Loss of appetite
This treatment can affect your appetite. Don’t worry if you do not eat much for 1 or 2 days. But if your appetite does not come back after a few days, or if you are losing weight, tell your doctor, nurse or pharmacist. They can give you advice. They may give you food or drink supplements. Or they may suggest changes to your diet or eating habits to help.
Tummy pain
You may get pain in your tummy (abdomen), or have indigestion. Your doctor, nurse or pharmacist can give you advice or treatment to help. Contact the hospital straight away on the 24-hour number if your symptoms do not go away, or get worse.
Feeling tired
Feeling tired is a common side effect of this treatment. It is often worse towards the end of treatment and for some weeks after it ends. Try to pace yourself and plan your day so you have time to rest. Gentle exercise, like short walks, can help you feel less tired.
If you feel sleepy, do not drive or use machinery.
Hair loss
Your hair will get thinner. Or you may lose all the hair from your head. You may also lose your eyelashes and eyebrows, as well as other body hair. Hair loss usually starts after your first or second treatment.
If you want to cover up hair loss, there are different ways you can do this. Your nurse will give you information about coping with hair loss.
Remember to protect your skin from the sun. Use suncream with a sun protection factor (SPF) of at least 30 on your scalp. Or cover up with a hat or scarf.
Hair loss is almost always temporary. Your hair will usually grow back after treatment ends.
Skin changes
Chemotherapy can affect your skin. It might feel dry. You may develop a rash, which may be itchy. Always tell your doctor, nurse or pharmacist about any skin changes. They can give you advice or prescribe creams or medicines to help.
If your skin feels dry, try using soap-free cleansers and unperfumed moisturising cream every day.
Hand-foot (palmar-plantar) syndrome
This treatment can affect the palms of your hands and the soles of your feet. This is called palmar-plantar or hand-foot syndrome.
If you have white skin these areas may become red. If you have black or brown skin, these areas might get darker.
The skin on the palms of your hands and the soles of your feet may:
- be sore
- be painful, tingle, or swell
- peel, crack or blister.
If you have any of these symptoms, contact the hospital straight away on the 24-hour number. They can give you advice. This is especially important if you have any broken skin or if walking is difficult. They can prescribe creams and painkillers to help.
You can care for your hands and feet by:
- keeping your hands and feet cool by washing in cool water
- gently moisturising your hands and feet regularly
- wearing gloves to protect your hands and nails when working in the house or garden
- wearing loose cotton socks and avoiding tight-fitting shoes and gloves.
Red urine
Your urine may be a pink-red colour for up to 48 hours after you have your treatment. This is caused by epirubicin and is not harmful.
Effects on the kidneys
Cisplatin can affect how the kidneys work. You will have blood tests before and during treatment to check how well your kidneys are working.
Before and after each treatment, your nurse will give you extra fluids through a drip. This is to protect your kidneys.
Drinking fluids also helps protect your kidneys. The advice is usually to try to drink at least 2 litres (3½ pints) of fluid each day. But follow any advice from your doctor, nurse or pharmacist about how much is right for you.
Contact the hospital on the 24-hour number if you are:
- not able to drink as much as you have been asked to – for example, if you feel sick
- sick (vomit) or have diarrhoea
- passing less urine or peeing less often than usual.
Other side effects
Numb or tingling hands or feet (peripheral neuropathy)
This treatment may affect the nerves in your fingers and toes. This can cause numbness, tingling or pain in your hands or feet. This is called peripheral neuropathy. You might find it hard to do fiddly tasks such as fastening buttons or tying shoelaces.
If you have these symptoms, always tell your doctor, nurse or pharmacist. They sometimes need to change the drug or the dose of the drug. The symptoms usually improve slowly after treatment ends. But for some people they continue and are a long-term side effect of treatment.
Nail changes
This treatment can affect your nails. They may grow more slowly or break more easily. You might notice ridges or white or dark lines across your nails. These changes usually disappear as the nails grow out after treatment. Sometimes nails can become loose or fall out.
If the skin around your nails becomes sore and swollen, contact the hospital straight away on the 24-hour number. These might be signs of an infection.
Tips to look after your nails:
- Keep your nails clipped short and clean.
- Avoid using very hot water when washing your hands or bathing.
- Moisturise your nails and cuticles regularly.
- It is okay to use water-based nail polish - but ask your cancer team if you want to use false nails, gels or other acrylics during treatment.
- Wear gloves to protect your nails when working in the house or garden.
- If your toenails are affected, wear well-fitting shoes, or shoes with open toes to cushion them.
Tell your doctor or nurse about any changes to your nails. They can give you advice or arrange for you to see a podiatrist. They are a foot care specialist.
Hearing changes
This treatment may cause hearing changes, including hearing loss. You may have ringing in the ears. This is called tinnitus. You may also become unable to hear some high-pitched sounds. Hearing changes may get better after this treatment ends. But this does not always happen. If you notice any changes in your hearing, tell your doctor, nurse or pharmacist.
Effects on the eyes
Your eyes may become watery and feel sore. Your doctor, nurse or pharmacist can give you advice and eye drops to help with this.
Contact the hospital on the 24-hour number if:
- your eyes get red and inflamed (conjunctivitis)
- you have pain in your eyes
- you notice any change in your vision.
Constipation
This treatment can cause constipation. Constipation means that you are not able to pass stools (poo) as often as you normally do. It can become difficult or painful. Here are some tips that may help:
- Drink at least 2 litres (3½ pints) of fluids each day.
- Eat high-fibre foods, such as fruit, vegetables and wholemeal bread.
- Do regular gentle exercise, like going for short walks.
If you have constipation, contact the hospital on the 24-hour number for advice. They can give you drugs called laxatives to help.
If you have not been able to pass stools for over 2 days and are being sick, contact the 24-hour number straight away.
Changes in the way the heart works
Capecitabine and epirubicin can affect how the heart works. You may have tests to see how well your heart is working. These may be done before, during and after treatment.
It is still possible for the heart to be affected even if these test results are normal. Very rarely, this can cause heart failure or a heart attack. The risk of this happening is very low (less than 1 in 100 or 1%). But it is important that you know about it.
Call your doctor straight away on the 24-hour number the hospital has given you if you have any of these symptoms at any time during treatment:
- pain or tightness in your chest
- breathlessness
- changes to your heartbeat.
If you have any of these symptoms, you should stop taking the capecitabine tablets until you have spoken to your doctor. If you cannot get through to your doctor, call the NHS urgent advice number on 111.
Effects on the liver
This treatment may affect how your liver works. This is usually mild. You will have blood tests to check how well your liver is working.
Serious skin changes
Rarely, this treatment can cause a serious skin reaction that needs to be treated immediately in hospital.
Do not take any more of this treatment and contact the hospital straight away on the 24-hour number if you have any of these symptoms:
- a skin rash that is spreading
- blistering or peeling skin
- flu-like symptoms, such as a high temperature and joint pain
- sores on your lips or in your mouth.
Headaches
This treatment may cause headaches. If you have headaches, tell your doctor, nurse or pharmacist. They can give you advice about painkillers that may help. Tell them if the headache does not get better, or gets worse.
Dizziness
Sometimes capecitabine may cause dizziness. Let your doctor know if you feel dizzy. It is important not to drive or operate machinery if you notice these effects.
Difficulty sleeping and mood changes
Sometimes capecitabine can cause sleeplessness (insomnia) or mood changes. Tell your doctor if you find it difficult to sleep or you feel low or depressed.
Other information
Blood clot risk
Cancer and some cancer treatments can increase the risk of a blood clot. Contact the hospital straight away on the 24-hour number if you have any of these symptoms during or after treatment:
- throbbing pain or swelling in a leg or arm
- reddening of the skin in the area – if you have black or brown skin, this can be harder to notice, but the skin might become darker
- suddenly feeling breathless or coughing.
Always call 999 if you have:
- chest pain
- difficulty breathing.
A blood clot is serious, but it can be treated with drugs called anticoagulants. These thin the blood. Your doctor, nurse or pharmacist can give you more information about preventing and treating blood clots.
Lactose
This treatment may contain lactose. If you have a lactose allergy or intolerance, ask your doctor, nurse or pharmacist for more information.
Other medicines
Some medicines can affect how this treatment works or be harmful while you are having it. Always tell your cancer doctor, nurse or pharmacist about any drugs you are taking or planning to take, such as:
- medicines you have been prescribed
- medicines you buy in a shop, pharmacy or online
- vitamins or supplements
- herbal drugs and complementary or homeopathic therapies
- recreational drugs – for example, cannabis.
Vaccinations
Cancer doctors usually recommend that people with cancer have vaccinations for flu and coronavirus (covid). They may also recommend other vaccines, such as Shingrix® for shingles. These all help reduce your risk of serious illness from these infections. Most people can have these vaccines, including people with weak immune systems.
You should not have live vaccines if your immune system is weak. This includes if you are having or recently had chemotherapy, radiotherapy or other cancer treatments that affect your immune system. Live vaccines can make you unwell because they contain a very weak version of the illness they protect you against. There are several live vaccines. These include the yellow fever vaccine and Zostavax®, which is a different type of shingles vaccine.
It is important to ask your doctor, nurse or pharmacist for advice about having vaccinations. They can explain what vaccines are right for you and when it is best to have them.
Contraception
Your doctor, nurse or pharmacist will advise you not to get pregnant or make someone pregnant while having this treatment and for some time afterwards. The drugs may harm a developing baby. It is important to use contraception to prevent pregnancy. Follow their advice about:
- what types of contraception to use
- how long after treatment you should continue to use contraception.
Breastfeeding
You are advised not to breastfeed while having this treatment, or for some time after treatment ends. This is because the drugs could be passed to the baby through breast milk.
Your doctor, nurse or pharmacist can give you more information.
Fertility
Some cancer drugs can affect whether you can get pregnant or make someone pregnant. If you are worried about this, it is important to talk with your doctor before you start treatment.
Sex
It is possible that small amounts of chemotherapy may be passed on through vaginal fluids or semen. If you have sex during this treatment, your cancer team will usually advise using condoms or a dental dam to protect your partner.
Medical and dental treatment
If you need medical treatment for any reason other than cancer, always tell the healthcare professional that you are having cancer treatment. Give them the contact details for your cancer doctor or cancer team so they can ask for advice.
If you have appointments with a dentist, always tell them you are having cancer treatment. Talk to your cancer team before you have any dental treatment.
