Chemoradiotherapy means having chemotherapy and radiotherapy treatment together.
Chemotherapy uses anti cancer (cytotoxic) drugs to destroy cancer cells. The drugs circulate throughout the body in the bloodstream.
Radiotherapy uses high energy waves similar to x-rays to kill cancer cells.
When do you have chemoradiotherapy for anal cancer?
Chemoradiotherapy is the most common treatment for anal cancer if your cancer hasn't spread to other parts of your body.
You might have surgery after chemoradiotherapy if it hasn't been successful or your cancer comes back.
What chemotherapy will I have?
Your exact treatment plan will depend on what your treatment team thinks is best for you.
The most common treatment is a combination of the chemotherapy drugs mitomycin C and fluorouracil (5FU). You have these drugs through a drip.
You might have a drug called capecitabine instead of fluorouracil (5FU). You take this as a tablet.
Having fluorouracil and mitomycin C
You have mitomycin and fluorouracil into your bloodstream. You start chemotherapy on the same day that you have your first radiotherapy treatment.
- mitomycin on day 1
- 5FU as a continuous infusion from day 1 to day 4
You then have no chemotherapy treatment but continue to have radiotherapy for several weeks.
At the beginning of week 5 of radiotherapy you have:
- 5FU as a continuous infusion from day 1 to day 4
You might need to stay in hospital while you have your chemotherapy treatments. Or you might be able to have the infusions of 5FU though a portable pump at home if you have a central line. A central line is a long plastic tube that goes into a large vein in your chest. The tube stays in place throughout the course of treatment.
Taking capecitabine tablets
You must take tablets according to the instructions your doctor or pharmacist gives you.
Whether you have a full or empty stomach can affect how much of a drug gets into your bloodstream.
You should take the right dose, not more or less.
Never stop taking a cancer drug without talking to your specialist first.
Hello, my name is Clare and this is a cancer day unit.
So when you arrive and you’ve reported into with the receptionist, one of the nurses will call you through when your treatment is ready, sit you down and go through all the treatment with you.
Morning, Iris, my name is Clare. I am the nurse who is going to be looking after you today. We’re going to start by putting a cannula in the back of your hand and giving you some anti sickness medication. And then I am going to come back to you and talk through the chemotherapy with you and the possible side effects you may experience throughout your treatment. Is that okay?
Before you have each treatment, you’ll need to have a blood test to check your bloods are okay. And you’ll also be reviewed by one of the doctors to make sure you’re fit and well for your treatment. Sometimes you’ll have the blood test taken on the day of your treatment; other times you’ll have it the day before your treatment when you see the doctor.
Each chemotherapy is made up for each individual patient, depending on the type of cancer they have and where it is and depending their height, weight and blood results.
So, depending on where your cancer is some people have their chemotherapy drug, their cancer drug by drip, some will have an injection and other people will have tablets.
So, Iris, your chemotherapy is going to be given to you in what we call cycles and the cycles are given every three weeks for a period of six cycles. So, you will be coming in for approximately five months for your chemotherapy.
Depending on where your cancer is and what type of cancer you have will be dependent on how often you come in for treatment. An example of a treatment cycle would be for you to come in on Day 1, Day 8 and Day 15 then to have a week’s break before you come back again for Day 1 treatment.
Depending on the type of treatment that you are having, we will also give you some anti sickness tablets to take alongside your chemotherapy and also some drugs to prevent any reactions if that’s appropriate.
All chemotherapy is given over different time periods, so it’s best to check with your nurse about how long you are likely to be in the unit for. This can range from anything up to an hour to an all day treatment slot, so please be prepared to bring along some bits to keep you occupied books and music.
So, before you go home it’s important to make sure you have got the tablets you need to go home with your anti sickness medications and any other symptom control tablets that you may require. Also, to make sure that you’ve got the telephone numbers for the oncology unit to phone if you have a temperature or you are experiencing any other symptoms at home that you need to ask advice about.
So, please make sure when you leave the unit that you’ve got all the information you require and if you’ve got any questions at all don’t hesitate to ask the nurse, who will be able to answer them for you.
Before your next cycle of treatment you will come in and see the doctor in the clinic room. You’ll have a blood test and an examination to make sure you are fit and well for treatment. You will then come back the following day or later on that week for treatment.
On the first day of chemotherapy you also have your first radiotherapy treatment.
You have treatment in the hospital radiotherapy department.
Before you begin treatment, the radiotherapy team work out how much radiation you need. They divide it into a number of smaller treatments. They call each treatment a fraction. At your planning appointment the radiographers might make pen marks or small tattoos on your skin in the treatment area.
Your treatment starts a few days or up to 3 weeks after the planning session. You have radiotherapy from an external machine as a daily treatment, five days a week for around 5 weeks.
Dan (radiographer): Before your treatment starts your doctor will need to work out exactly where the treatment needs to go and also which parts need to be avoided by the treatment. To have radiotherapy you lie in the same position as you did for your planning scans. We then line up the machine based on your tattoo marks. It is really important that you stay very, very still when you are having treatment it is also important to let the radiographers know right at the beginning if you are not comfortable so they can adjust your position.
Radiographer: Ok all done, we’ll be back in a couple of minutes.
Dan (radiographer): We leave the room and control the room from a separate room This is so we aren’t exposed to radiation. Treatment takes a few minutes and you will be able to talk to us using an intercom. We can see and hear you while you are having your treatment and will check that you are ok. When your treatment starts you won’t feel anything; you may hear the machine as it moves around you giving the treatment from different angles. Because we are aiming to give the same treatment to the same part of the body everyday then the treatment process is exactly the same everyday so you shouldn’t notice any difference. You’ll see someone from the team caring for you once a week while you are having treatment they’ll ask how you are and about any side effects.
Patient: They get you from one sitting area to another and then take you into the room where you undress to the waist and then lie down and line you up by either moving you or asking you to shuffle a little and they check the dimensions and they talk to one another and they say I am fine this side how are you ...yes fine...ok, stay where you are Jeff and that was it. There were a few little clicks and lights go on and off and you can see a green laser beam which line sup with certain things on your body uh so no, no real noise and no discomfort.
You might have side effects from chemoradiotherapy to the anus. These can be more severe than either radiotherapy or chemotherapy on their own.
Side effects can include:
- feeling tired
- opening your bowels more often (diarrhoea)
- sore skin around the anus and groin - which can make opening your bowels more painful
Tell your nurse or doctor if this happens. They can give you painkillers and tell you about how to look after your skin.
Use only creams or dressings on your skin that your nurse or doctor recommends.
Between 2 and 8 out of 100 people (2 to 8%) have low levels of an enzyme called DPD in their bodies. A lack of DPD can mean you’re more likely to have severe side effects from capecitabine or fluorouracil. It might take you a bit longer to recover from the chemotherapy. These side effects can rarely be life threatening.
Low DPD levels don’t cause symptoms so you won’t know if you have a deficiency. You should have a test before you start this treatment to check if you have a DPD deficiency.
Some people have severe side effects from capecitabine or fluorouracil even if they don't have low DPD levels. Contact your doctor or nurse if your side effects are severe.
