Last year in the UK over 60,000 cancer patients enrolled on clinical trials aimed at improving cancer treatments and making them available to all.
A trial looking at higher dose radiotherapy for non small cell lung cancer (I-START)
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
This trial is looking at giving a higher than normal dose of radiotherapy for non small cell lung cancer. This trial is supported by Cancer Research UK.
Researchers think that giving a higher dose of radiotherapy may kill off more cancer cells. But they want to do this without damaging the surrounding healthy tissue such as your food pipe.
In this trial, they will increase the amount of radiotherapy and see how well it works on the cancer cells. They will also check what effect more radiotherapy has on the nearby healthy cells.
The aims of this trial are to find out
- If increasing the amount of radiotherapy you have each day is better at killing the cancer cells
- What the maximum safe dose of radiotherapy is to your food pipe (oesophagus)
- How well this maximum dose works
- Whether the higher dose causes more or worse side effects
Who can enter
You may be able to enter this trial if you
- Have non small cell lung cancer that is stage 2, 3A or 3B
- Have been told your cancer cannot be treated with surgery or you have chosen not to have surgery
- Are well enough to be up and about for at least half the day (performance status 0, 1 or 2)
- Have satisfactory
lung function tests
- Have satisfactory blood test results
- Are willing to use reliable contraception if you or your partner could become pregnant
- Are at least 16 years old
You cannot enter this trial if
- You have already had radiotherapy to your chest
- You have a type of lung cancer called a Pancoast tumour
- One of your lungs or a section (lobe) of one of your lungs isn't working properly
- You have a
connective tissuedisorder such as scleroderma or systemic lupus erythematosus
- You have had another cancer that could affect you taking part in this trial
- You have another medical condition that is not controlled with medication
- You are pregnant or breastfeeding
There are 2 parts to this phase 1/2 trial. In the first part, the researchers want to find the highest dose of radiotherapy they can give.
Everybody taking part will have radiotherapy. The first few people will have a dose that is a little bit higher than what you would receive for your normal treatment. If they don’t have any serious side effects, the next few people will have a slightly higher dose again. As long as there are no serious side effects this will be repeated twice more with higher doses. In this way the researchers find the highest dose they can give safely. This is called a ‘dose escalation’ study.
In the second part of the trial, the researchers will give the highest dose possible based on what they know from part 1. The researchers will give a higher dose than standard as long as the dose to other parts of your body is still safe. This part will also find out how well the highest dose of radiotherapy works. It will also see if a higher dose makes the side effects worse.
You have radiotherapy once a day from Monday to Friday for 4 weeks.
You see the doctor and have some tests before taking part in this trial. These tests include
- Chest X-ray
- CT scan
- PET scan
Lung function test
- Blood test
- A physical examination
- Heart trace (
- Bone scan – if needed
During treatment you see the doctor every week for a physical examination and blood test.
When you finish treatment you go back and see the doctor about 1 month later for a physical examination and blood test.
After that you see the doctor every month for 3 months and then every 3 months for 2 years. At each visit you have a physical examination and chest X-ray. After 12 weeks you have a lung function test and a CT scan. After a year you have another lung function test. The researchers will also ask you how you have been and if you have any side effects.
The side effects of radiotherapy for lung cancer can include
- Sore throat and difficulty when swallowing
- Skin reaction
- Lung scarring (fibrosis) which can cause breathlessness many months after your treatment
