Chemotherapy for lung cancer

What chemotherapy is

Chemotherapy means using anti cancer (cytotoxic) drugs to destroy cancer cells. These work by disrupting the growth of cancer cells.
 

Chemotherapy for small cell lung cancer

Chemotherapy is the main treatment for small cell lung cancer. Doctors use it because
  • This type of cancer responds very well to chemotherapy
  • Small cell lung cancer tends to have spread beyond the lung when it is diagnosed
Chemotherapy drugs circulate in the bloodstream around the body. So they can treat cells that have broken away from the lung tumour and spread to other parts of the body even if they are too small to see on scans. This microscopic spread often happens even in the early stages of small cell lung cancer.
Often chemotherapy is used on its own. Or you may have chemotherapy before or after radiotherapy (or at the same time). If you are to have surgery for very early small cell lung cancer, your doctor may suggest that you have chemotherapy before or after surgery.
Doctors usually give a combination of chemotherapy drugs, including either cisplatin or carboplatin (Paraplatin). The combinations include
Small cell lung cancer usually responds well to these treatments, but researchers are continuing to test other combinations to see if they can either improve the results, lessen the side effects, or both.
For cancer that has come back after treatment, doctors may use one of the treatments above or one of the following chemotherapy combinations
People who have medical conditions that mean they cannot have CAV or ACE chemotherapy may have topotecan chemotherapy capsules.
There is information about current chemotherapy research in the lung cancer research page in this section. And you can find out about clinical trials on our clinical trials database. Choose 'lung' from the dropdown menu of cancer types.
 

Chemotherapy for non small cell lung cancer

Doctors use chemotherapy to treat non small cell lung cancer in the following situations

Chemotherapy after surgery

Chemotherapy after surgery for early stage NSCLC can help to lower the risk of the cancer coming back. It is important that your doctor talks to you beforehand about the benefits and possible risks of chemotherapy because the drugs can cause side effects. Chemotherapy tends to work best in patients who are fit. If you are fit enough to have chemotherapy you usually start it within about 8 weeks of having surgery.
Combinations of chemotherapy tend to work better than single drugs. Usually doctors combine cisplatin or carboplatin (Paraplatin) with at least one other drug such as

Chemotherapy and radiotherapy

Giving chemotherapy before or after radiotherapy can sometimes help to get rid of early stage NSCLC in people who can't have surgery. The chemotherapy drugs will usually be the same as mentioned above.
These treatments can also help some people with advanced non small cell lung cancer to live longer even if they are not likely to be cured of their cancer. If you are fairly fit, your doctor may suggest combined treatment with radiotherapy and chemotherapy (chemoradiation) as the best way of trying to control it.

Chemotherapy for locally advanced NSCLC or cancer that has spread

Locally advanced lung cancer means that the cancer has spread beyond the lung into surrounding tissues or nearby lymph nodes. Metastatic lung cancer means the cancer has spread into other organs or lymph nodes far away in the body. Chemotherapy can help to shrink or slow the growth of locally advanced or metastatic NSCLC. It can also help to control symptoms for some people.
Your doctor will usually offer you treatment with either cisplatin or carboplatin combined with one of the following drugs
If you have cisplatin and pemetrexed treatment and your cancer shrinks, your specialist may recommend that you continue with pemetrexed treatment on its own. Doctors call this pemetrexed maintenance treatment. The National Institute for Health and Clinical Excellence (NICE) is assessing this treatment at the moment.
If your cancer continues to grow during chemotherapy, your doctor may recommend docetaxel (Taxotere) chemotherapy if you have not had that before. Or your doctor may recommend changing to another chemotherapy treatment.
If your cancer cells have particular proteins that make them respond to biological therapy drugs such as erlotinib (Tarceva), gefitinib (Iressa) or crizotinib (Xalkori) your doctor may suggest that you have one of these. We have a page about biological therapy treatments for lung cancer.
Your doctor will talk to you in detail about the possible risks and benefits of further treatment. These treatments will not help everybody. It will depend on how fit you are, and how able you are to cope with any side effects.
 

How you have chemotherapy

You have most chemotherapy drugs by injection into a vein or through a drip. But some are tablets or capsules that you swallow.
How you have the drugs, and how often, depends on which drugs you are having. Usually, you have treatment with a combination of drugs. You will need to ask your chemotherapy nurse or doctor to explain the details of your treatment to you.
Most often, you have the chemotherapy treatment every 3 to 4 weeks. Then you have a rest period to allow your body to get over any side effects. The number of treatments you have depends on
  • Which drugs you are having
  • The type of lung cancer you have
  • How well the treatment is working
  • How your body is coping with the side effects
You can have most chemotherapy drugs as an outpatient. So you go into the hospital or clinic for the day to have treatment and go home afterwards. Your chemotherapy nurse will give you medicines to take home in case you need them to control side effects.
Some chemotherapy drugs have to be given in hospital. Usually this is because you have to have them through a drip over a number of hours. So depending on your treatment, you may have to stay overnight, or for a few days.
 

How many treatments you may have

Most chemotherapy is given for 4 to 6 treatments. So a full course can take 3 to 6 months.
If you are having treatment to control symptoms, the aim of the treatment is to help you feel better. Your doctor will keep an eye on your progress by monitoring your symptoms and possibly by checking the size of your cancer on scans and X-rays.
If the treatment is working well you will continue with the treatment. If the treatment is not working well your doctor will suggest changing to a different treatment or stopping it.
It may be very upsetting if your doctor tells you that they are stopping your treatment after only a few treatments when you thought you would have more. But you can talk to your doctor or specialist nurse about the other treatment options open to you.
 

Dietary or herbal supplements and chemotherapy

We don't yet know much scientifically about how some nutritional or herbal supplements may interact with chemotherapy. Some could be harmful. It is very important to let your doctors know if you take any supplements. Or if you are prescribed therapies by alternative or complementary therapy practitioners.
Talk to your specialist about any other tablets or medicines you take while you are having cancer treatment. There is information about the safety of herbal, vitamin and diet supplements in the complementary therapies section.
Some studies seem to suggest that fish oil preparations may reduce the effectiveness of chemotherapy drugs. If you are taking or thinking of taking these supplements talk to your doctor to find out whether they could affect your treatment.
 

Getting more information

You can look at the main chemotherapy section. It has detailed information about
You can ask your doctor or chemotherapy nurse to write down the names of the drugs you will have so you can look them up in our specific drug side effects section. There are pages there for all the most commonly used chemotherapy drugs. Each drug page has information about common, occasional, and rare side effects for that drug.
You can phone the Cancer research UK nurses on freephone 0808 800 4040, from 9am to 5pm, Monday to Friday. Our lung cancer organisations page gives details of people who can give information about lung cancer chemotherapy. Some organisations can put you in touch with a cancer support group. Our lung cancer reading list has information about books and leaflets on lung cancer treatments.
If you want to find people to share experiences with online, you could use CancerChat, our online forum. Or you can go through My Wavelength. This is a free service that aims to put people with similar medical conditions in touch with each other.

 

Why you get side effects

Chemotherapy drugs kill cells that are dividing. Cancer cells divide more often than normal cells. But some normal body cells also divide quickly and so are also affected by chemotherapy. Quickly dividing cells include those in your skin, hair, nails, the lining of your digestive system, and your blood cells. Unlike cancer cells, these normal body tissues can recover. So you usually have a couple of weeks break between treatments to allow your normal body tissues to get over the effects of the chemotherapy.
Chemotherapy affects different people in different ways. Your doctor or chemotherapy nurse can tell you what may happen. But they can't tell beforehand exactly what treatment will be like for you. It isn't something you can easily predict. Side effects are worse for some people than others. Many people can go on with their normal lives during their treatment and some can even carry on working. Other people find that they are very tired and have to take things more slowly. Side effects may seem hard to bear at the time. But most disappear when your treatment ends.
Remember that not all chemotherapy drugs cause the same side effects and some people have very few. There is detailed information about the side effects of specific drugs in the cancer treatment section.
This page gives information about the common side effects of lung cancer chemotherapy.
 

Low blood cell levels

Chemotherapy can lower the number of healthy white blood cells, red blood cells and platelets you have. This can mean that you
  • Are more likely to get infections
  • May be more tired than usual
  • Can be prone to nosebleeds and other bleeding problems
If you develop a temperature above 38°C or think you have an infection, it is very important to contact the hospital immediately. You may need urgent treatment with antibiotics. Your doctor or chemotherapy nurse will give you an emergency number to phone if you need to.
It isn't practical to try to avoid all germs while you are having chemotherapy, but it is important to keep away from anyone you know who has an infection. Avoid crowded, cramped places such as public transport.
There is information about the effect of chemotherapy on your blood cells in the main chemotherapy section.
 

Feeling tired and run down

Some people are able to carry on almost as normal when they are having chemotherapy. But many others become very tired. The further through your course of chemotherapy treatment you are, the more likely you are to feel tired and run down. If this is happening to you, try to take things more slowly. If you feel like having a lie down or putting your feet up, then you probably need to do just that.
It can help to ask other people to do some things for you so that you can rest if you need to. Other family members or friends can often help with household jobs or shopping. We have information about coping with tiredness. The tiredness may last for some months after your treatment has ended. How quickly you get back to normal will depend on your general health, on the amount of treatment you've had, and on other treatments you have had.
 

Feeling sick

Sickness is a common chemotherapy side effect. Some drugs only make you feel mildly sick. Others can make some people vomit a lot and feel very sick. There is a page about coping with sickness in the cancer drugs side effects section. Nausea and sickness can now usually be well controlled with anti sickness drugs. Tell your doctor or chemotherapy nurse if you feel sick, as they can prescribe other anti sickness drugs, which may suit you better.
 

Taste changes

Some chemotherapy drugs can affect your sense of taste. Foods may taste metallic, salty or bitter, or may not taste of anything. These changes should go away after your treatment ends. We have information about coping with taste changes.
 

Sore mouth and mouth ulcers

Some chemotherapy drugs cause mouth ulcers or soreness in the mouth. To try to prevent infection, it is important to keep your mouth clean. It is best to use a very soft (or baby) toothbrush to avoid damaging the lining of your mouth. If you are likely to get a sore mouth, your nurse will give you mouthwashes to use regularly to help prevent infection. If the soreness gets very bad, you may need painkillers until it has healed. We have information about coping with a sore mouth in the chemotherapy side effects section.
 

Diarrhoea

Some chemotherapy drugs cause diarrhoea. This can be mild or more severe. If you have diarrhoea for more than 2 or 3 days, you must tell your doctor or nurse. You could become dehydrated, and may need to have anti diarrhoea tablets or medicines.
Your doctor or specialist nurse can also give you advice about what to eat or drink if you have diarrhoea. You may also find our information about coping with diarrhoea helpful.
 

Hair loss or thinning

Not all drugs cause complete hair loss. Some don't cause hair loss at all. Some nearly always do. With others your hair may just get thinner during the treatment. Hair usually starts to fall out about 2 to 3 weeks after the chemotherapy begins. It will grow back once the treatment is over. Ask your doctor or nurse whether you are likely to lose your hair. Then you can plan how to cope with this.
Many people wear hats, scarves or wigs. It can be less upsetting to cut your hair short, or even have your head shaved, if you know you are going to lose your hair. Find out about getting a free wig on the NHS. Ask your doctor or nurse about it as soon as you know you will have chemotherapy. It can take some time to arrange and you have to be an inpatient when it is ordered and collected.
We have a page about coping with hair loss due to chemotherapy.
 

Hearing changes

Some chemotherapy drugs for lung cancer cause ringing in the ears (tinnitus). You may also find that you can't hear some high pitched sounds. Some people also feel dizzy and lose their sense of balance. Let your doctor or nurse know if you have any change in your hearing or if you feel dizzy.
