EOX is a combination treatment used to treat cancers of the gullet (oesophagus) and stomach.
It is best to read this information with our general information about chemotherapy and the type of cancer you have.
EOX is usually given into a vein. You usually have it as an outpatient or during a hospital stay. Your cancer doctor, nurse or pharmacist will tell you how often you will have it.
EOX can cause side effects. Some of the side effects can be serious, so it is important to read the detailed information below.
Your healthcare team can give you advice on how to manage any side effects. Tell your doctor or nurse straight away if you:
Rarely, side effects may be life-threatening. Your cancer doctor or nurse can explain the risk of these side effects to you.
If you need medical attention for any reason other than cancer, always tell the healthcare staff that you are having this treatment.
Your doctor will talk to you about this treatment and its possible side effects before you agree (consent) to have treatment.
EOX is named after the initials of the drugs used in the treatment. The drugs are:
You might hear the treatment called EEX. This is because the other name for oxaliplatin is Eloxatin®.
You will be given EOX in the chemotherapy day unit or during a stay in hospital. A chemotherapy nurse will give it to you.
During treatment you usually see a cancer doctor, a chemotherapy nurse or a specialist nurse, and a specialist pharmacist. This is who we mean when we mention doctor, nurse or pharmacist in this information.
Before or on the day of treatment, a nurse or person trained to take blood (phlebotomist) will take a blood sample from you. This is to check that your blood cells are at a safe level to have chemotherapy.
You will see a doctor or nurse before you have chemotherapy. They will ask you how you have been feeling. If your blood results are okay, the pharmacist will prepare your chemotherapy. Your nurse will tell you when your treatment is likely to be ready.
Your nurse usually gives you anti-sickness (anti-emetic) drugs before the chemotherapy. The chemotherapy drugs can be given through:
Your nurse will give you epirubicin (a red fluid) as an injection directly into your line or cannula, with a drip (infusion) of fluids to flush it through. Then you have oxaliplatin as a drip. The nurse usually runs the drip through a pump, which gives you the treatment over a set time.
You take capecitabine as tablets, which you take at home.
You will have chemotherapy as a course of several sessions (or cycles) of treatment over a few months.
Each cycle of EOX takes 21 days (3 weeks).
On the first day you will have epirubicin and oxaliplatin and you will start the capecitabine tablets. Over the next 3 weeks you continue to take the capecitabine tablets.
When it finishes on day 21, you will start the next cycle of EOX. This is the same as the first cycle. Your doctor or nurse will tell you the number of cycles that you are likely to have.
Capecitabine is taken as tablets. The nurse or pharmacist gives you the capecitabine tablets to take at home. Always take your tablets exactly as explained. This is to make sure they work as well as possible for you.
You take capecitabine tablets twice a day. Swallow them whole with a glass of water within half an hour after eating a meal. Take the tablets in the morning after breakfast and then after your evening meal. Tell your doctor if you find it difficult to swallow the tablets. They may suggest that you dissolve the capecitabine tablets in water. In this case, dissolve the tablets in a 200ml glass of warm water. Stir the water with a spoon until the tablets are completely dissolved and then drink it immediately. The glass and spoon should be washed and kept separate from your other crockery and cooking utensils.If you forget to take a tablet, do not take a double dose. Take your next dose at the normal time and let your doctor or nurse know. Other things to remember about your capsules:
We explain the most common side effects of this treatment here. We also include some less common side effects.
You may get some of the side effects we mention, but you are unlikely to get all of them. If you are also having treatment with other cancer drugs, you may have some side effects that we haven’t listed here. Always tell your doctor, nurse or pharmacist about any side effects you have.
Your doctor can give you drugs to help control some side effects. It is important to take them exactly as your nurse or pharmacist explains. This means they will be more likely to work for you. Your nurse will give you advice about managing your side effects. After your treatment is over, most side effects start to improve.
Some cancer treatments can cause severe side effects. Rarely, these may be life-threatening. Your cancer doctor or nurse can explain the risk of these side effects to you.
Rarely, capecitabine can cause severe side effects in people who have low levels of an enzyme called DPD. This is called having a DPD deficiency. You will not know before you start treatment whether you have a DPD deficiency as there are no symptoms. There is a test available but it only tests for the more common types of DPD deficiency. This means that the test will detect most cases of DPD deficiency but not all cases. The test is not widely available on the NHS. Talk to your doctor if you are worried about having a DPD deficiency.
Your nurse will give you telephone numbers for the hospital. If you feel unwell or need advice, you can call them at any time of the day or night.
Save these numbers in your phone or keep them somewhere safe.
We cannot list every side effect for this treatment. There are some rare side effects that are not listed. You can visit the electronic Medicines Compendium (eMC) for more detailed information.
Some people may have side effects while they are being given the chemotherapy or shortly after they have it:
Some people have an allergic reaction while having this treatment. Signs of a reaction can include:
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, it can be treated quickly.
Sometimes a reaction can happen a few hours after treatment. If you get any signs or feel unwell after you get home, contact the hospital straight away.
Rarely, oxaliplatin can affect the area around the voicebox (larynx). This can cause difficulties with swallowing and breathing. This might happen during treatment or in the first few days after treatment. This side effect can be very frightening, but it should only be temporary. If you have breathing difficulties, take long, deep breaths through your nose. This will have a calming effect and help your breathing return to normal.
This symptom may be worse in cold temperatures, so it’s advisable to avoid cold drinks and ice cubes during treatment and for a few days afterwards. It might also help to wrap up warm and cover your nose and mouth in cold weather.
It’s important to let your doctor know if you have this side effect. Your doctor may increase the time of your infusion to 4 to 6 hours in future cycles, which will reduce the chance of it happening again.
If this happens it can damage the tissue around the vein. This is called extravasation. Extravasation is not common but if it happens it is important that it is dealt with quickly. Tell your nurse straight away if you have any stinging, pain, redness, or swelling around the vein.
If you get any of these symptoms after you get home, contact the doctor or nurse straight away on the number they gave you.
This treatment can cause pain at the place where the injection is given or along the vein. If you feel pain, tell your nurse or doctor straight away so that they can check the site. They may give the drug more slowly or flush it through with more fluid to reduce pain.
You may suddenly feel warm and your face may get red while the drug is being given. This should only last a few minutes.
This treatment can reduce the number of white blood cells in your blood. These cells fight infection.
If the number of white blood cells is low, you are more likely to get an infection. A low white blood cell count is called neutropenia.
If you have an infection, it is important to treat it as soon as possible.
Contact the hospital straight away on the 24-hour contact number you have if:
Symptoms of an infection include:
It is important to follow any specific advice your cancer treatment team gives you.
The number of white blood cells 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.
This treatment can reduce the number of platelets in your blood. Platelets are cells that help the blood to clot.
Tell your doctor if you have any bruising or bleeding that you cannot explain.
Some people may need a drip to give them extra platelets. This is called a platelet transfusion.
This treatment can reduce the number of red blood cells in your blood. These cells carry oxygen around the body.
If the number of red blood cells is low, you may be tired and breathless. Tell your doctor or nurse if you feel like this.
If you are very anaemic, you may need a drip to give you extra red blood cells. This is called a blood transfusion.
You may feel sick in the first few days after this treatment. Your doctor will give you anti-sickness drugs to help prevent or control sickness. Take the drugs exactly as your nurse or pharmacist tells you.
It is easier to prevent sickness than to treat it after it has started.
If you feel sick, take small sips of fluids and eat small amounts often.
If you continue to feel sick, or if you vomit more than once in 24 hours, contact the hospital as soon as possible. They will give you advice and may change the anti-sickness drug to one that works better for you.
Feeling tired is a common side effect. It is often worse towards the end of treatment and for some weeks after it has finished.
Try to pace yourself and plan your day so you have time to rest.
Gentle exercise, like short walks, can give you more energy.
If you feel sleepy, do not drive or operate machinery.
Capecitabine may cause diarrhoea. This can be severe. Your nurse or doctor may give you anti-diarrhoea drugs to take at home.
If you have diarrhoea:
Contact the hospital straight away if:
Your doctor may ask you to stop taking capecitabine. When the diarrhoea is better, they will tell you if you can start taking it again. Sometimes the dose is reduced.
This treatment can cause constipation. Here are some tips that may help:
If you have constipation, contact the hospital for advice. Your doctor can give you drugs called laxatives to help.
You may get a sore mouth or mouth ulcers. This can make you more likely to get a mouth infection.
Use a soft toothbrush to clean your teeth or dentures in the morning, at night and after meals.
If your mouth is sore:
Your hair will get thinner or you may lose all the hair from your head. You may also lose your eyelashes, eyebrows or other body hair. Hair loss usually starts after your first or second treatment.
Your nurse can talk to you about ways to cope with hair loss. There are ways to cover up hair loss if you want to. It is important to cover your head to protect your scalp when you are out in the sun.
Hair loss is almost always temporary and your hair will usually grow back after treatment ends.
Capecitabine may affect your skin. Your doctor or nurse can tell you what to expect. If your skin feels dry, try using an unperfumed moisturising cream every day. Capecitabine can cause a rash, which may be itchy. Always tell your doctor or nurse about any skin changes. They can give you advice and may give you creams or medicines to help. Any changes to your skin are usually temporary and improve when treatment finishes.
Very rarely, a much more serious skin condition can occur. You may have a skin rash which then blisters and your skin can peel. You may also feel unwell with flu-like symptoms such as a high temperature and joint pain. If you have these symptoms, you must stop taking the capecitabine and contact your doctors immediately.
This is called palmar-plantar or hand-foot syndrome. Your doctor or nurse can give you advice and prescribe creams to improve the symptoms. It can help to keep your hands and feet cool and to avoid tight-fitting socks, shoes and gloves. It will start to get better when treatment ends.
This treatment affects the nerves, which can cause numb, tingling or painful hands or feet. You may find it hard to fasten buttons or do other fiddly tasks.
Tell your doctor if you have these symptoms. They sometimes need to lower the dose of the drug.
The symptoms usually improve slowly after treatment finishes, but for some people they may never go away. Talk to your doctor if you are worried about this.
Your nails may grow more slowly or break more easily. You may notice white lines across your nails, or other changes to their shape or colour. Once the treatment has ended, any changes usually take a few months to grow out.
There are things you can do to look after your nails:
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.
Your eyes may become watery and feel sore. They may also become red and inflamed, which is called conjunctivitis. Tell your doctor if you have any of these symptoms. You may need antibiotic eye drops.
This treatment may cause headaches. If this happens, tell your doctor or nurse. They can give you painkillers.
Capecitabine can affect the way your heart works. You may have tests to see how your heart is working before, during and sometimes after treatment. But it is still possible for your heart to be affected even if these tests are normal. Very rarely, this can lead to heart failure or a heart attack. The risk of this happening is very low (less than 1 in 100 1%), but it is important that you know about it. Tell a doctor immediately if you have any of these symptoms at any time during treatment:
If you experience 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 or the 24-hour number the hospital has given you, then call the NHS urgent advice number which is 111.
Cancer and some cancer treatments can increase the risk of a blood clot. Symptoms of a blood clot include:
If you have any of these symptoms, contact a doctor straight away.
A blood clot is serious, but can be treated with drugs that thin the blood. Your doctor or nurse can give you more information.
Some medicines can affect chemotherapy or be harmful when you are having it. This includes medicines you can buy in a shop or chemist.
Tell your cancer doctor about any drugs you are taking, including over-the-counter drugs, complementary therapies and herbal drugs.
Your doctor will advise you not to get pregnant or make someone pregnant while having this treatment. The drugs may harm a developing baby. It is important to use contraception during your treatment and for a while after treatment finishes. Your doctor, nurse or pharmacist can tell you more about this.
Women are advised not to breastfeed while having this treatment and for some time afterwards. This is because the drugs could be passed to the baby through breast milk.
Some cancer drugs can affect whether you can get pregnant or make someone pregnant.
If you are a woman, your periods may become irregular or stop. This may be temporary, but for some women it is permanent. Your menopause may start sooner than it would have done.
If you have sex during this course of chemotherapy, you need to use a condom. This is to protect your partner in case there is any chemotherapy in semen or vaginal fluids.
If you need medical treatment for any reason other than cancer, always tell the doctors and nurses that you are having cancer treatment.
Give them the contact details for your cancer doctor so they can ask for advice.
If you think you need dental treatment, talk to your cancer doctor or nurse. Always tell your dentist you are having cancer treatment.
If you have a lot on your mind, you might find it useful to make a checklist. You can use our checklists for home, work and travel to help you get organised.
Order booklets or audio CDs about chemotherapy. It includes how it works, having treatment and how it might affect you.
All types of treatment can have different side effects. Know what to expect to help you find the best way for you to handle them.
