Information for patients having Radiotherapy for Lung Cancer

Introduction

The process of informed consent requires patients to receive written information to help them to make a decision about treatment.

This page is a written version of the information your oncology doctor has told you about radiotherapy for lung cancer. It includes sections on the most commonly asked questions, about the treatment procedure and the side-effects, which may occur with this sort of treatment.

Whilst it is important to make you aware of side-effects associated with the treatment it is equally important to put this into perspective. We hope this page will help you weigh up the benefits of having adequate treatment now against the risks of late side-effects of radiotherapy treatment.

 The page is only a short summary. Throughout the process the doctors, radiographers and nurses will be there to explain what will happen in more detail and to answer any questions you may have.

 If you need further advice please do not hesitate to ask. The bottom of this page has further suggestions of where you may wish to go for help.

 

What is Radiotherapy?

  • Radiotherapy is the use of high energy x-rays to treat cancer. The x-rays are produced by a machine called a linear accelerator and are able to damage and destroy cancer cells within the treatment area.

  • Radiotherapy also affects normal cells in the area being treated, but they are generally more able to recover than cancer cells.

  • Treatment is usually given regularly over a period of time to have the greatest effect on the cancer cells whilst limiting the damage to normal cells.

 

When is it used?

Radiotherapy can be used:

  • To treat cancer before or after surgery.

  • To treat early stage cancer.

  • To treat symptoms of cancer.

 

How is it given?

Radiotherapy is normally given in daily sessions - Monday to Friday as an outpatient and weekends off. The length of your treatment schedule will be discussed with you by your oncology doctor.

Radiotherapy should be given as a continuous daily treatment and therefore appointments ideally should not be missed. If you are too unwell or have an emergency and unable to attend your appointment, you should inform the radiographers as soon as possible.

If any scheduled ‘breaks’ are required during your treatment, such as Bank Holidays etc. you will be informed prior to starting your treatment.

 

Is there any preparation for the procedure?

In some circumstances, you may be required to follow special dietary instructions or specific bladder and bowel preparations. You will be informed of this before the appointment.

 

Planning your treatment

The aim of treatment is to treat the tumour whilst sparing as much of the surrounding healthy tissue as possible where it is safe to do so. To do this an individual plan is prepared for each patient. You will have a CT scan in the radiotherapy department and this will be used to prepare and plan your treatment.

CT contrast agent is used to enhance the images produced by CT scans to help with the planning of your radiotherapy treatment. Contrast agents are also called “contrast mediums” and “dyes”.

There are different types of contrast agent that can be used. Some are given by injection into a vein (intravenously), others are swallowed.

If this is something that you require, your oncology doctor will talk to you about this and may send you for a blood test prior to your planning appointment.

Once the area for treatment has been decided, small permanent skin marks, the size of a pinhead are made with a needle and ink (tattoos). This enables the Radiographers to achieve an accurate and consistent treatment each day.

 

What does the treatment involve?

It takes approximately between 10 and 20 minutes to position and treat you. The treatment is given using a machine called a linear accelerator. You lie on a treatment couch. The radiographers position you using laser lights and marks that have been put on your skin or treatment mask.

Once you are in the correct position the radiographers will ask you to stay very still and breathe normally. The machine may be re-positioned (to different angles) during the session by the radiographers. X-Ray pictures will be taken before the radiation beam is switched on. This will allow the radiographers to ensure accurate positioning and treatment delivery.

You will be in the room on your own whilst the radiation beam is on. The treatment team will monitor you on closed circuit television. If at any time you want the attention of the staff, you will be asked to raise your hand.

 

Will I be radioactive?

No. As soon as the radiation beam is completed all the radiation disappears. Once the treatment is finished you will be free to go home. It will be perfectly safe to be with other people including children.

 

Will the procedure be painful?

The treatment itself is totally painless. There is nothing to see or feel - you will hear the machine buzzing.

The treatment couch is quite firm to ensure accuracy but you will be made as comfortable as possible in the treatment position.

 

What side effects can I expect?

The effect of radiotherapy is dependent on the dose that is prescribed, the length and area of your treatment as well as whether you are having any chemotherapy. If you are, then this may have additional effects.

For most patients, side effects usually settle after a few weeks or months but it is possible that some side effects may be permanent and require further medical intervention.

The review radiographer team will be able to advise you on how to ensure side effects are kept to a minimum and any self-help measures. If necessary there are various medications that can be prescribed to help, so it is important to let staff know if you develop any problems.

For the majority of patients, some level of tiredness can be experienced. It is important to keep hydrated and ensure that you rest as and when necessary.

 

Short term side effects

  • Occasionally your breathing may get worse before it gets better

  • Difficulty swallowing

  • Pain or aches in the area being treated.

 

 

Long term side effects

It is important to remember that serious side-effects are rare, and experts agree that the benefits of treatment outweigh the risk of possible serious side-effects.

There are some rare side-effects, some of which can be serious and permanent. These include:

  • Scarring of the lung causing shortness of breath in 5% of patients.

  • Permanent subtle skin changes in the treatment area.

  • Occasionally narrowing of the gullet may cause difficulty with swallowing.

  • Very rarely another tumour may develop.

  • Spinal cord damage occurs in 1 in 1,000 patients.

 

Your medical team will be able to advise you on how to ensure that any side-effects are kept to a minimum. If necessary there are various medications that can be prescribed to help you, so it is important to let staff know if you develop any problems.

You will be given information and advice on how to deal with these problems by the treatment team.

 

If you have further questions

If you are at all concerned about the treatment, what it involves and what it means for you, do not hesitate to ask at any time.
