Why am I having pemetrexed and carboplatin chemotherapy?
Your doctor has recommended this chemotherapy because it has been found to be effective in treating your type of cancer.
What is pemetrexed and carboplatin chemotherapy?
This is a chemotherapy treatment which consists of two drugs called pemetrexed and carboplatin. As part of your treatment we will also give you vitamin supplements which you must start before your chemotherapy.
Why must I take the vitamin supplements?
Taking vitamins before, during and after pemetrexed will reduce the risk of serious side effects. You will be given a vitamin B12 injection the week before your chemotherapy. This will be repeated twice during your treatment. You will also need to take multivitamin capsules containing folic acid once a day starting one week before your chemotherapy. These need to be taken every day during your chemotherapy and for three weeks after.
Will I need to take any other medicine before my chemotherapy?
Yes, we will give you steroid tablets called dexamethasone.
It is very important that you take the dexamethasone steroid tablets to reduce some of the side effects associated with this chemotherapy. You must take the tablets for five days, starting the day before you have your chemotherapy. They should be taken with food. It is very important to take them exactly as instructed.
Will I need any tests before I have my chemotherapy?
You will need a series of blood tests before you start your chemotherapy. One of these blood tests helps us to check that your kidneys are working well enough to cope with the chemotherapy.
How often will I receive my chemotherapy?
For this treatment to be most effective it is given at specific time intervals. These are known as cycles. It is usual to have pemetrexed and carboplatin treatment every three weeks for between three - six cycles. Your doctor will discuss with you the exact number of cycles you will have.
How will my chemotherapy be given?
Your chemotherapy is given through a drip into a vein in the back of your hand or arm. Alternatively it may be suggested that a fine tube called a PICC is inserted into a large vein in your upper arm. This will remain in place throughout the course of your treatment. Your doctor or nurse will discuss this further with you, if needed and will provide you with a leaflet that tells you more about PICC lines.
How often will I need to visit the hospital?
You will need to visit the hospital twice in every three week cycle:
Outpatient clinic appointment – you will have a blood test and we will check how you are feeling and discuss any problems you may have. This is so we can check how the chemotherapy is affecting you. If your blood results are satisfactory, your chemotherapy will be prescribed. This appointment is usually a few days before your chemotherapy appointment.
Chemotherapy appointment – you will spend approximately two hours on one of the day case treatment areas. Please allow up to 30 minutes longer for your first visit.
Can I bring relatives and friends with me?
You are welcome to bring someone to stay with you during your treatment. Space is limited so there is not usually room for more than one person. Treatment areas are not suitable for young children.
What are the possible side effects?
There are a number of possible side effects which can occur with this chemotherapy. The doctors, nurses and pharmacists can give you advice or answer any questions you may have.
It is very important that before you start your chemotherapy you:
Hair loss
You should not lose your hair with this chemotherapy. However, a very small number of patients may experience some hair thinning.
Sickness
Nausea and vomiting are uncommon these days as we will give you anti-sickness medicines which are usually extremely effective. If you are sick more than once in 24 hours despite taking regular anti-sickness medicine when you are at home after your chemotherapy treatment, contact Velindre Cancer Centre for advice. The telephone number is at the end of the leaflet.
Infection
You are at an increased risk of picking up infections because your white blood cells which help fight infections can be reduced by this treatment.
If you develop an infection whilst your white blood cells are low, you are at risk of sepsis, this can be life threatening.
Contact Velindre Cancer Centre immediately if you develop any signs of infection, for example flu like symptoms or a temperature above 37.5°centigrade or below 35.5°centigrade. The telephone number is at the end of the leaflet.
Diarrhoea
You may have diarrhoea with this chemotherapy. If this occurs it is important that you drink plenty of fluids. Medication is available to control diarrhoea. If you have four or more bowel movements in 24 hours above what is normal for you please contact Velindre Cancer Centre immediately. The telephone number is at the end of the leaflet.
Tiredness and fatigue
Chemotherapy can make you feel more tired than usual. It is important to listen to your body and rest if you need to, but carry out your normal activities if you feel able. Some people find it beneficial to take gentle exercise as well as rest.
Sore mouth
Your mouth may become sore or you may notice small ulcers. Please follow the advice on caring for your mouth in the general chemotherapy leaflet. Your doctor may prescribe mouthwashes or medication to prevent or clear any infection.
Blood clots
A diagnosis of cancer can increase your risk of developing a blood clot (thrombosis), and having cancer treatment may increase this risk further. It is important to tell your doctor immediately if you have symptoms such as pain, redness and swelling in your leg, or breathlessness and chest pain.
Blood clots can be very serious. However, most clots can usually be successfully treated with drugs to thin the blood. Your doctor or nurse can give you more information.
Other side effects
Skin rash
Pemetrexed can cause skin rashes or irritation. These are normally prevented by taking the dexamethasone tablets as directed. Using a moisturising cream may help. If the rash becomes uncomfortable please contact Velindre Cancer Centre for advice. The telephone number is at the end of the leaflet.
Allergic type reaction
A small number of patients experience an allergic type reaction. If this occurs you may feel hot or flushed, itchy, light-headed or generally unwell whilst receiving your carboplatin. This can be easily treated, however, you must tell your nurse immediately if you experience any of the above symptoms. Rarely this can be life threatening.
Some patients experience sore or watery eyes. If this happens please tell your doctor or nurse at your next clinic appointment.
Women sometimes find that chemotherapy treatment affects their periods. They could become heavier, lighter or even stop altogether.
It is important you do not become pregnant or father a child whilst having chemotherapy treatment as chemotherapy could damage the unborn baby.
This chemotherapy can increase your skin’s sensitivity to the sun. It is best to avoid strong sunlight, wear a hat and use a sun block.
Rare side effects
Pemetrexed may cause some heart problems. If you have a heart condition or you take any heart medication, please tell your doctor before you start chemotherapy.
Is it alright to take other medicines?
If you are taking other medicines please let your doctor, nurse or pharmacist know. There are a small number of medicines that you may have to avoid. Please tell your doctor, nurse or pharmacist if you take any painkillers as some anti-inflammatory tablets must not be taken with pemetrexed.
You must also tell your doctor if you have recently received a Yellow Fever vaccine.
Sometimes cancer drugs can have very serious side effects which rarely can be life threatening. It is important to inform Velindre cancer centre if you are concerned about any side-effects.
