A trial of white light or blue light surgery for people with bladder cancer (PHOTO)
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
This trial is comparing a white light with a blue light during surgery for people who have been recently diagnosed with early bladder cancer.
More about this trial
Doctors usually treat early bladder cancer with surgery to remove the tumours. This surgery is called a transurethral resection of bladder tumour or TURBT. The surgeon looks inside the bladder using a telescope called a cystoscope. They shine a white light through the telescope to see the cancer and remove it.
In this trial, the researchers want to test using a blue light during surgery alongside a liquid that is put into the bladder. The liquid is absorbed by the cancer cells and glows red under the blue light. This may help them to see the areas of cancer more clearly and remove it.
The aim of the trial is to compare the blue light with the standard white light to find out which is better at showing up areas of cancer in the bladder.
You may not get any direct benefit from taking part in this trial, but it may help people with early bladder cancer in the future.
Who can enter
You may be able to join this trial if all of the following apply. You
- Have recently been told that your doctors suspect you have early stage bladder cancer that hasn’t grown into the muscle wall (stage Ta or T1)
- Have a medium to high risk of your bladder cancer coming back (the trial team can advise you about this)
- Are at least 16 years old
You cannot join this trial if any of these apply.
- You have already had surgery to remove your bladder cancer
- Your bladder cancer has grown through the muscle wall of the bladder or further (T2, T3 or T4 bladder cancer)
- You have a low risk of your cancer coming back (the trial team can advise you about this)
- You have only one small area of cancer measuring less than 3cm across
- Your cancer is also in either kidney or the tubes that carry urine from the kidney to the bladder (ureters)
- You have a condition called porphyria or you are known to be very sensitive to porphyrins (the trial team can tell you more about what they are)
- You have had any other cancer in the last 2 years, apart from certain very early stage cancers (the trial team can advise you about this)
- You have any other condition that could affect you taking part in this trial
- You are pregnant or breastfeeding
The researchers need 533 people to join this randomised trial. You are put into 1 of 2 groups by a computer. Neither you nor your doctor can decide which group you are in.
- People in one group have surgery with the standard white light
- People in the other group have a surgery with the blue light
Everyone taking part will have surgery to remove the tumours from their bladder. The people in the white light group have surgery as usual.
The people in the blue light group have a liquid called HAL put into their bladder through a fine tube called a catheter 1 hour before surgery. You will be asked not to pass urine for an hour to give the HAL time to work. You then go on to have your surgery with the blue light.
If you agree to take part in this trial, the researchers may ask for extra blood samples, urine samples and samples of your cancer (a
The trial team will ask you to fill out a questionnaire at set times during the trial. The questionnaires will ask about side effects and how you’ve been feeling. This is called a quality of life study.
You go to hospital for your surgery and will need to stay in for a few days afterwards. You will see the doctor for routine check ups after surgery. But you won’t have any extra hospital visits as a result of taking part in this trial.
The side effects of HAL are rare, and include
- Feeling sick
- Constipation or diarrhoea
The trial team will explain the risks of having surgery to you.
