You might have chemotherapy if you have advanced stomach cancer. Chemotherapy uses anti cancer (cytotoxic) drugs to destroy cancer cells. The drugs circulate throughout your body in the bloodstream.
Advanced stomach cancer is a cancer that began in the stomach and has spread to another part of the body.
When do you have chemotherapy?
You might have chemotherapy for advanced cancer if your doctor thinks you might benefit from the treatment and you are well enough.
Chemotherapy for advanced stomach cancer can relieve symptoms. It can also control the cancer and improve your quality of life for a time. But it can’t cure the disease. Your doctor or specialist nurse can talk with you about the benefits and possible side effects.
You usually have chemotherapy every 2 or 3 weeks depending on what drugs you have. Each 3 week period is called a cycle. Your doctor will tell you how many cycles they plan to give you.
Types of chemotherapy
Your doctor will make a plan for your treatment. How often you have treatment depends on this plan. Your doctor might change what chemotherapy you have depending on your side effects.
There are different chemotherapy drugs that you might have for advanced stomach cancer. You usually have a combination of 2 or 3 drugs. The most common types are:
- cisplatin and capecitabine (XP)
- epirubicin, cisplatin and capecitabine (ECX)
- epirubicin,cisplatin,fluorouracil (ECF)
- epirubicin, oxaliplatin and capecitabine (EOX)
- epirubicin, carboplatin, capecitabine (ECarboX)
- fluorouracil, folinic acid, oxaliplatin and docetaxel (FLOT)
Other drugs you may have include:
You might hear the terms first line and second line treatment. The first course of chemotherapy you have is the first line treatment. Your doctor might offer you second line treatment if your cancer starts to grow again or first line treatment isn't working.
Targeted cancer drugs
For advanced stomach cancer with HER2 protein, you might have:
- trastuzumab (Herceptin) and XP (cisplatin and capecitabine)
- trastuzumab (Herceptin) and cisplatin and 5-FU
Trastuzumab is a type of targeted cancer drugs. These treatments interfere with the way cells work. They can boost the body's immune system to help fight off or destroy cancer cells, or they can block signals telling cells to grow.
How you have chemotherapy
You have most of the chemotherapy drugs for stomach cancer into your bloodstream (intravenously). Capecitabine is a tablet.
Into your bloodstream
You have treatment through a thin short tube (a cannula) that goes into a vein in your arm each time you have treatment.
Or you might have treatment through a long line: a central line, a PICC line or a portacath. These are long plastic tubes that give the drug into a large vein in your chest. The tube stays in place throughout the course of treatment.
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.
Talk to your specialist or advice line before you stop taking a cancer drug.
Where you have chemotherapy
You usually have treatment into your bloodstream at the cancer day clinic. You might sit in a chair for a few hours so it’s a good idea to take newspapers, books or electronic devices to help to pass the time. You can usually bring a friend or family member with you.
You have some types of chemotherapy over several days. You might be able to have some drugs through a small portable pump that you take home.
For some types of chemotherapy you have to stay in a hospital ward. This could be overnight or for a couple of days.
Clare Disney (nurse): 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.
Before you start chemotherapy
You need to have blood tests to make sure it’s safe to start your treatment. You have these either a few days before or on the day your treatment begins. You have blood tests before each round or cycle of treatment.
Before your first chemotherapy, your doctor will explain what drugs you need, how you have them, and what the side effects are. You’ll sign a consent form. This is a good time to ask any questions you might have.
Common chemotherapy side effects include:
- feeling sick
- loss of appetite
- losing weight
- feeling very tired
- a lower resistance to infections
- bleeding and bruising easily
- diarrhoea or constipation
- hair loss
Side effects depend on:
- which drugs you have
- how much of each drug you have
- how you react
Tell your treatment team about any side effects that you have.
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. Talk to your doctor if you are worried and about whether you need to have a test to check for it.
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.
When you go home
Chemotherapy for advanced stomach cancer can be difficult to cope with. Tell your doctor or nurse about any problems or side effects you have. The nurse will give you telephone numbers to call if you have any problems at home.
