Cisplatin and topotecan chemotherapy (CT)

What is cisplatin and topotecan?

Cisplatin and topotecan is a chemotherapy treatment used to treat cervical and ovarian cancers.

This information should ideally be read with our general information about chemotherapy and the type of cancer you have.


The drugs used in CT


How CT is given

You usually have cisplatin and topotecan in the chemotherapy day unit or during a short 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. This is who we mean when we mention doctor or nurse 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 it is okay for you to have chemotherapy.

You will also see a doctor or nurse before you have chemotherapy. They will ask you how you have been. If your blood results are all right on the day of the treatment, the pharmacist will prepare your chemotherapy. Your nurse will tell you when your treatment is likely to be ready.

Your nurse will give you anti-sickness (anti-emetic) drugs, and sometimes a steroid, as an injection into a vein or as tablets. They give you the drugs and chemotherapy through one of the following:

  • a short, thin tube that they put 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).

Your nurse will give you topotecan (a colourless fluid) as a drip (infusion) for 30 minutes. After this, they will give you cisplatin as a drip over a longer period of time. They usually run the drip through a pump, which gives you the treatment over a set time. You’ll have extra fluids through your drip before and after the cisplatin. This is to protect your kidneys.

When CT is being given

Some people might have side effects while they are having the chemotherapy:

Allergic reaction

Rarely, CT may cause an allergic reaction while it’s being given. Your nurse will check you for this. If you have a reaction, they will treat it quickly. Signs of a reaction can include:

  • a rash
  • feeling itchy, flushed or short of breath
  • swelling of your face or lips
  • feeling dizzy
  • having pain in your tummy, back or chest
  • feeling unwell.

Tell your nurse straight away if you have any of these symptoms.

Your course of cisplatin and topotecan

You will have chemotherapy as a course of several sessions (cycles) of treatment over a few months. Each cycle of cisplatin and topotecan takes 21 days (three weeks). CT can be given in different ways. Your doctor or nurse will be able to give you details of your treatment course.

  • On day 1, you have topotecan and cisplatin.
  • On day 2, you have just topotecan.
  • On day 3, you have topotecan again.
  • You then have a rest period with no chemotherapy for 18 days. Or you may be given topotecan at the beginning of the second week (on day 8) and then a week later (on day 15).

At the end of the 21 days, you start your second cycle of treatment. This is exactly the same as the first cycle. Your doctor or nurse will tell you the number of cycles you are likely to have.

Going home

Before you go home, the nurse or pharmacist will give you anti-sickness drugs to take. They may also give you anti-diarrhoea tablets if you need them. Take all your tablets exactly as your nurse or pharmacist has explained.


Possible side effects of CT

We explain the most common side effects of CT here. But we don’t include all the rare ones that are unlikely to affect you.

You may get some of the side effects we mention, but you are very unlikely to get all of them. Always tell your doctor or nurse about the side effects you have.

Your doctor can prescribe drugs to help control some of these. It is very important to take the drugs exactly as your nurse or pharmacist has explained. This means they will be more likely to work better for you. Your nurse will give you advice about managing your side effects. After your treatment is over, the side effects will 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.

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.

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 (99.5F)
  • 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 chemotherapy. If your white blood cell count is low, your doctor may delay your treatment for a short time.

Bruising and bleeding

Chemotherapy can reduce the number of platelets in your blood. Platelets are cells that help the blood to clot. Tell your doctor or nurse if you have any bruising or bleeding that you can’t 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)

Chemotherapy 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 chemotherapy. 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.

Changes to your taste

You may get a bitter or metal taste in your mouth. Sucking sugar-free sweets may help with this. Some foods may taste bad or have no taste. Try different foods to find out what tastes best to you. Taste changes usually get better after treatment finishes. Your nurse can give you more advice.

Loss of appetite

This treatment can affect your appetite. Do not worry if you don’t 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.

Hair loss

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.

Tiredness

Feeling very tired is a common side effect. It’s often worse towards the end of treatment and for some weeks after it’s finished. Try to pace yourself and get as much rest as you need. It helps to balance this with some gentle exercise, such as short walks. If you feel sleepy, don’t drive or operate machinery.

Effects on the kidneys

Cisplatin can affect how your kidneys work. You will have blood tests before and during treatment to check this. 

Before and after each treatment, your nurses will give you extra fluids through a drip. This is to protect your kidneys. It’s also important to drink at least two litres (three and a half pints) of fluids each day.  

If you pass less urine than usual, tell your nurse.

Numb or tingling hands or feet (peripheral neuropathy)

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 or delay treatment for a short time. 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.


Less common side effects of CT

Changes in hearing

Cisplatin can affect your hearing. You may have a hearing test before you start treatment. You may get ringing in your ears (tinnitus) and lose the ability to hear some high-pitched sounds. Tinnitus usually gets better after treatment ends. Some hearing changes can be permanent. Tell your doctor if you notice any changes in your hearing.

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.

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

If you have diarrhoea, contact the hospital for advice. Try to drink at least two litres (three and a half pints) of fluids every day. It can help to avoid alcohol, caffeine, milk products, high-fat foods and high-fibre foods.


Other information about CT

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.

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.

Contraception

Your doctor will advise you not to get pregnant or father a child while having this treatment. The drugs may harm the developing baby. It is important to use effective contraception.

Sex

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.

Changes to your periods

Chemotherapy can sometimes stop the ovaries working. You may not get a period every month and they may eventually stop. In some women this is temporary, but for others it is permanent and they start the menopause.

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.

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.
