Treatment

Treatment for lung cancer is managed by a team of specialists from different departments who work together to provide the best possible treatment.

This team includes the health professionals required to make a diagnosis, to stage your cancer and to plan the best treatment. If you want to know more, ask your doctor or nurse about this.

The type of treatment you receive for lung cancer depends on several factors, including:

Deciding what treatment is best for you can be difficult. Your cancer team will make recommendations, but the final decision will be yours.

The most common treatment options include surgery, radiotherapy, chemotherapy and immunotherapy. Depending on the type of cancer and the stage, you may receive a combination of these treatments.

Your treatment plan

Your suggested treatment plan depends on whether you have non-small-cell lung cancer or small-cell lung cancer.

Non-small-cell lung cancer

If you have non-small-cell lung cancer that's in only 1 of your lungs and you're in good general health, you'll probably have surgery to remove the cancerous cells. This may be followed by a course of chemotherapy to destroy any cancer cells that may have remained in your body.

If the cancer has not spread far but surgery is not possible (for example, because your general health means you have an increased risk of complications), you may be offered radiotherapy to destroy the cancerous cells. In some cases, this may be combined with chemotherapy (known as chemoradiotherapy).

If the cancer has spread too far for surgery or radiotherapy to be effective, chemotherapy and / or immunotherapy is usually recommended. If the cancer starts to grow again after you have had chemotherapy treatment, another course of treatment may be recommended.

In some cases, if the cancer has a specific mutation, biological or targeted therapy may be recommended instead of chemotherapy, or after chemotherapy. Biological therapies are medicines that control or stop the growth of cancer cells.

Small-cell lung cancer

Small-cell lung cancer is usually treated with chemotherapy, either on its own or in combination with radiotherapy. This can help to prolong life and relieve symptoms.

Surgery isn't usually used to treat this type of lung cancer. This is because the cancer has often already spread to other areas of the body by the time it's diagnosed. However, if the cancer is found very early, surgery may be used. In these cases, chemotherapy or radiotherapy may be given after surgery to help reduce the risk of the cancer returning.

Surgery

There are 3 types of lung cancer surgery:

People may be concerned about being able to breathe if some or all of a lung is removed, but it's possible to breathe normally with 1 lung. However, if you have breathing problems before the operation, it's likely these symptoms will continue after surgery.

Tests before surgery

Before surgery, you'll need to have some tests to check your general state of health and your lung function. These may include:

How it's performed

Surgery is usually done by making a cut (incision) in your chest or side and removing a section or all of the affected lung. Nearby lymph nodes may also be removed if it's thought that the cancer may have spread to them.

In some cases, an alternative to this approach, called video-assisted thoracoscopic surgery (VATS), may be suitable. VATS is a type of keyhole surgery, where small incisions are made in the chest. A small camera is inserted into one of the incisions, so the surgeon can see the inside of your chest on a monitor as they remove the section of affected lung.

After the operation

You'll probably be able to go home 5 to 10 days after your operation. However, it can take many weeks to recover fully from a lung operation.

After your operation, you'll be encouraged to start moving as soon as possible. Even if you have to stay in bed, you'll need to keep doing regular leg movements to help your circulation and prevent blood clots from forming. A physiotherapist will show you breathing exercises to help prevent complications.

When you go home, you'll need to exercise gently to build up your strength and fitness. Walking and swimming are good forms of exercise that are suitable for most people after treatment for lung cancer. Talk to your care team about which types of exercise are suitable for you.

Complications

As with all surgery, lung surgery carries a risk of complications. It is estimated that around 1 in 5 lung cancer surgeries will lead to complications. These complications can usually be treated using medicine or more surgery, which may mean you need to stay in hospital for longer.

Complications of lung surgery can include:

Radiotherapy

Radiotherapy uses pulses of radiation to destroy cancer cells. There are a number of ways it can be used to treat lung cancer.

An intensive course of radiotherapy, known as radical radiotherapy, may be used to treat non-small-cell lung cancer if you are not healthy enough for surgery. For very small tumours, a special type of radiotherapy called stereotactic radiotherapy may be used instead of surgery.

Radiotherapy can also be used to control the symptoms, such as pain and coughing up blood, and to slow the spread of cancer when a cure is not possible (this is known as palliative radiotherapy).

A type of radiotherapy known as prophylactic cranial irradiation (PCI) is also sometimes used during the treatment of small-cell lung cancer. PCI involves treating the whole brain with a low dose of radiation. It's used as a preventative measure because there's a risk that small-cell lung cancer will spread to your brain.

The 3 main ways that radiotherapy can be given are:

For lung cancer, external beam radiotherapy is used more often than internal radiotherapy, particularly if it's thought that a cure is possible. Stereotactic radiotherapy may be used to treat tumours that are very small, as it's more effective than standard radiotherapy alone in these circumstances.

Internal radiotherapy is usually used as a palliative treatment when the cancer is blocking or partly blocking your airway.

Courses of treatment

Radiotherapy treatment can be planned in several different ways.

People having conventional radical radiotherapy are likely to have 20 to 32 treatment sessions.

Radical radiotherapy is usually given 5 days a week, with a break at weekends. Each session of radiotherapy lasts 10 to 15 minutes and the course usually lasts 4 to 7 weeks.

Continuous hyperfractionated accelerated radiotherapy (CHART) is an alternative way of giving radical radiotherapy. CHART is given 3 times a day for 12 days in a row.

Stereotactic radiotherapy requires fewer treatment sessions because a higher dose of radiation is given during each treatment. People having stereotactic radiotherapy usually have 3 to 10 treatment sessions.

Palliative radiotherapy usually involves 1 to 5 sessions. 

Side effects

Side effects of radiotherapy to the chest include:

Side effects should pass after the radiotherapy has been completed.

Chemotherapy

Chemotherapy uses powerful cancer-killing medicine to treat cancer. There are several ways that chemotherapy can be used to treat lung cancer. For example, it can be:

Chemotherapy treatments are usually given in cycles. A cycle involves taking chemotherapy medicine for several days, then having a break for a few weeks to let the therapy work and for your body to recover from the effects of the treatment.

The number of cycles you need will depend on the type and grade of lung cancer.

Most people need 4 to 6 cycles of treatment over 3 to 6 months. You will see your doctor after these cycles have finished. If the cancer has improved, you may not need any more treatment.

If the cancer has not improved after these cycles, your doctor will tell you if you need a different type of chemotherapy. Alternatively, you may need maintenance chemotherapy to keep the cancer under control.

Chemotherapy for lung cancer involves taking a combination of different medicines. The medicines are usually given through a drip into a vein (intravenously), or into a tube connected to one of the blood vessels in your chest. Some people may be given capsules or tablets to swallow instead.

Before you start chemotherapy, your doctor might prescribe you some vitamins and/or give you a vitamin injection. These help to reduce some the side effects.

Side effects

Side effects of chemotherapy can include:

These side effects should gradually pass after treatment has finished, or you may be able to take other medicines to make you feel better during your chemotherapy.

Chemotherapy can also weaken your immune system, making you more vulnerable to infection. Tell your care team or GP as soon as possible if you have signs of an infection, such as a high temperature, or you suddenly feel generally unwell.

Immunotherapy is a group of medicines that stimulate your immune system to target and kill cancer cells.

Immunotherapy can be used on its own or combined with chemotherapy.

A immunotherapy medicine called pembrolizumab is an option for non-small cell lung cancer. It is given through a drip into a vein in your arm or hand.

It takes around 30 minutes to receive a dose, and you will normally take a dose every 3 weeks. If the side effects are not too difficult to manage and the therapy is successful, immunotherapy can be taken for up to 2 years.

Side effects of pembrolizumab include:

Targeted therapies (also known as biological therapies) are medicines designed to slow the spread of advanced non-small cell lung cancer.

Targeted therapies are only suitable for people who have certain proteins in their cancerous cells. Your doctor may request tests on cells removed from your lung (a biopsy) to see if these treatments are suitable for you.

Side-effects of targeted therapies include:

Other treatments

As well as surgery, radiotherapy and chemotherapy, other treatments are sometimes used to treat lung cancer, such as:

Radiofrequency ablation

Radiofrequency ablation may be used to treat non-small-cell lung cancer at an early stage.

The doctor uses a CT scanner to guide a needle to the site of the tumour. The needle is pressed into the tumour and radio waves are sent through the needle. These waves generate heat, which kills the cancer cells.

The most common complication of radiofrequency ablation is a pocket of air may become trapped between the inner and outer layer of your lung (pneumothorax). This can be treated by placing a tube into the lungs to release the trapped air.

Cryotherapy

Cryotherapy can be used if the cancer starts to block your airways. This is known as endobronchial obstruction, and it can cause symptoms such as:

Cryotherapy is done in a similar way to internal radiotherapy, but instead of using a radioactive source, a device known as a cryoprobe is placed against the tumour. The cryoprobe can generate very cold temperatures, which help to shrink the tumour.

Photodynamic therapy

Photodynamic therapy (PDT) can be used to treat early-stage lung cancer when a person is unable or unwilling to have surgery. It can also be used to remove a tumour that's blocking the airways.

Photodynamic therapy is done in 2 stages. First you'll be given an injection of a medicine that makes the cells in your body very sensitive to light.

The next stage is done 24 to 72 hours later. A thin tube is guided to the site of the tumour and a laser is beamed through it. The cancerous cells, which have become more sensitive to light, are destroyed by the laser beam.

Side effects of PDT can include inflammation of the airways and a build-up of fluid in the lungs. Both these side effects can cause breathlessness and lung and throat pain. However, these symptoms should gradually pass as your lungs recover from the effects of the treatment.

Will the NHS fund an unlicensed medicine if my doctor wants to prescribe it?

Your doctor can prescribe a medicine outside its licensed use if they're willing to take personal responsibility for this "off-licence" use of the medicine.

Your local clinical commissioning group (CCG) may need to be involved, as it would have to decide whether to support your doctor’s decision and pay for the medication from NHS budgets.
