de Gramont

de Gramont and modified de Gramont are combination treatments used to treat bowel cancer. They may also be used to treat other cancers. Both treatments use the same drugs but in slightly different ways.

It is best to read this information with our general information about chemotherapy and the type of cancer you have.

de Gramont and modified de Gramont are usually given into a vein. You usually have them as an outpatient or during a hospital stay. Your cancer doctor, nurse or pharmacist will tell you how often you will have it.

Like all chemotherapy drugs, these treatments 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:

  • have a temperature
  • feel unwell
  • have severe side effects, including any we do not mention here.

Rarely, side effects may be life-threatening. Your cancer doctor, nurse or pharmacist 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.

What are de Gramont and modified de Gramont?

de Gramont and modified de Gramont are used to treat bowel cancer. They 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.

The de Gramont treatments use the following drugs:

Folinic acid is not a chemotherapy drug, but doctors often give it with 5FU. For some cancers, folinic acid makes 5FU work better.

How de Gramont and modified de Gramont are given

You will be given your treatment in the chemotherapy day unit or during a stay in hospital. A chemotherapy nurse will give it to you. de Gramont and modified de Gramont can be given in combination with other cancer drugs.

During treatment, you usually see a cancer doctor, a chemotherapy nurse or 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:

  • a short, thin tube the nurse puts into a vein in your arm or hand (cannula)
  • a fine tube that goes under the skin of your chest and into a vein close by (central line)
  • a fine tube that is put into a vein in your arm and goes up into a vein in your chest (PICC line).

If you have a cannula, you will need to stay in hospital while your treatment is given.

If you have a central line or a PICC line, part of the treatment can be given by a small portable pump. This can be carried on a belt or in a bag. You can go home with the pump. The nurses will tell you how to look after it. When the pump has finished, you go to the hospital so it can be disconnected. Sometimes a district nurse can do this in your home.

For both treatments, after your infusion has finished you will have a rest period of 11 days before starting the treatment again. This is one treatment cycle. Each cycle takes 14 days (two weeks).

de Gramont

Day 1:

  • You have folinic acid as a drip (infusion) over two hours.
  • You then have 5FU as an injection. This is given into your cannula or line. This usually takes about five minutes.
  • After this, you have 5FU as an infusion over 22 hours as a drip or through a portable pump.

Day 2: You have the same treatment you had on day 1.

Day 3: The 5FU infusion finishes. If you have a portable pump, this will be disconnected.

Sometimes, the infusion pump is filled with enough 5FU to last for 44 hours. Then your nurse will stop the pump after the first 22 hours to give you the folinic acid and injection of 5FU. They will then restart it.

Modified de Gramont

Day 1:

  • You have folinic acid as a drip (infusion) over two hours.
  • You then have 5FU as an injection. This is given into your cannula or line. This usually takes about five minutes.
  • After this, you have 5FU as an infusion over 46 hours as a drip or through a portable pump.

Day 3: The 5FU infusion finishes. If you have a portable pump, this will be disconnected.

Your course of chemotherapy

You usually have a course of several cycles of treatment over a few months. Your nurse or doctor will discuss your treatment plan with you.

About side effects

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.

Serious and life-threatening side effects

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, fluorouracil 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.

Contact the hospital

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.

More information

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.


Side effects while treatment is being given

Some people may have side effects while they are being given the chemotherapy or shortly after they have it:

Allergic reaction

Some people have an allergic reaction while having this treatment. Signs of a reaction can include:

  • feeling hot or flushed 
  • a skin rash
  • itching
  • shivering
  • feeling dizzy
  • a headache
  • feeling breathless 
  • 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, 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.

Pain or tightening in your chest

If you have pain or tightening in your chest, tell your nurse or doctor straight away.


Common side effects

Risk of infection

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:

  • your temperature goes over 37.5°C (99.5°F)
  • you suddenly feel unwell, even with a normal temperature
  • you have symptoms of an infection.

Symptoms of an infection include:

  • feeling shivery
  • a sore throat
  • a cough
  • diarrhoea
  • needing to pass urine often.

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.

Bruising and bleeding

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. This includes:

  • nosebleeds
  • bleeding gums
  • tiny red or purple spots on the skin that may look like a rash.

Some people may need a drip to give them 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. 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.

Feeling sick

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.

Sore mouth

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.

Contact the hospital straight away if you have a sore mouth.

If your mouth is sore:

  • tell your nurse or doctor – they can give you a mouthwash or medicines to help
  • try to drink plenty of fluids
  • avoid alcohol, tobacco, and foods that irritate your mouth.

Diarrhoea

This treatment may cause severe diarrhoea. Your nurse or doctor may give you anti-diarrhoea drugs to take at home.

If you have diarrhoea:

  • follow any advice you have been given about taking anti-diarrhoea drugs
  • drink at least two litres (three and a half pints) of fluids each day
  • avoid alcohol, caffeine, milk products, high-fat foods and high-fibre foods.

Contact the hospital straight away if:

  • you have diarrhoea at night
  • you have diarrhoea more than two times in a day
  • the anti-diarrhoea drugs don’t work within 24 hours.

Some people may need to go to hospital to have fluids through a drip. You may need to take antibiotics.

Feeling tired

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.

Loss of appetite

This treatment can affect your appetite. Do not worry if you do not eat much for a day or two. But if your appetite does not come back after a few days, tell your nurse or dietitian. They will give you advice. They may give you food or drink supplements.

Soreness and redness of palms of hands and soles of feet

This is called palmar-plantar or hand-foot syndrome. It gets better when treatment ends. Your doctor or nurse can give you advice and creams to improve the symptoms. It can help to keep your hands and feet well moisturised, cool and to avoid tight-fitting socks, shoes and gloves. Tell your nurse about any changes in your hands or feet.

Hair loss

Your hair may get thinner but you are unlikely to lose all the hair from your head. Hair loss usually starts after your first or second treatment. It is almost always temporary and your hair will usually grow back after treatment ends. Your nurse can talk to you about ways to cope with hair loss.

Eye problems

This treatment may make your eyes feel sore, red and itchy (conjunctivitis). Your doctor will prescribe eye drops to help prevent this. Your pharmacist will tell you how to use your eye drops. It is important to follow their advice.

It may also make your eyes more sensitive to light and cause blurry vision. If you have pain or notice any change in your vision, always tell your doctor or nurse.

Less common side effects

Effects on the heart

This treatment can affect the way the heart works. You may have tests to see how well your heart is working. These may be done before, during, and sometimes after treatment. If the treatment is causing heart problems, your doctor can change the type of treatment you are having.

Contact a doctor straight away if you:

  • have pain or tightness in your chest
  • feel breathless or dizzy
  • feel your heart is beating too fast or too slowly.

Other conditions can cause these symptoms, but it is important to get them checked by a doctor.

Skin changes

Chemotherapy 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. Always tell your doctor or nurse about any skin changes. They can give you advice and may prescribe creams or medicines to help. Any changes to your skin are usually temporary and improve when treatment finishes.

During treatment and for several months afterwards, you'll be more sensitive to the sun and your skin may burn more easily than usual. You can still go out in the sun, but use a sun cream with a sun protection factor (SPF) of at least 30, and cover up with clothing and a hat. Your skin may darken. It will return to its normal colour after you finish treatment.

Effects on the nervous system

This treatment can affect the nervous system. You may feel drowsy or confused, dizzy or unsteady. Tell your doctor or nurse straight away if you notice any of these symptoms. They may make some changes to your treatment if they become a problem for you. It is important not to drive or operate machinery if you notice these effects.


Common side effects

Blood clot risk

Cancer and some cancer treatments can increase the risk of a blood clot. Symptoms of a blood clot include:

  • pain, redness or swelling in a leg or arm
  • breathlessness
  • chest pain. 

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.

Other medicines

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 vitamins, herbal drugs and complementary therapies.

Contraception

Your doctor will advise you not to get pregnant or father a child while having this treatment and for at least six months afterwards. The drugs may harm the developing baby. It is important to use effective contraception during your treatment.

Breastfeeding

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.

Fertility

Some cancer drugs can affect whether you can get pregnant or father a child. If you are worried about this, it is important to talk with your doctor before you start treatment.

Sex

If you have sex in the first few days after chemotherapy, you need to use a condom. This is to protect your partner in case there is any chemotherapy in semen or vaginal fluids.

Medical and dental treatment

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.
