A trial looking at MRI scans to pick up early signs of prostate cancer pressing on the spine (PROMPTS)
Sometimes prostate cancer can spread to the backbone (spine). This can cause pressure on the long bundle of nerves in the backbone (the spinal cord). Doctors call this spinal cord compression. The symptoms of spinal cord compression include pain and numbness. People with spinal cord compression need to have treatment quickly to relieve the pressure.
Doctors often use an MRI scan to confirm any symptoms of spinal cord compression. The researchers think that MRI scans may be used to find early signs of spinal cord compression before symptoms happen. This means treatment can start earlier, which may prevent the most severe symptoms.
The aim of this trial is to see if MRI scans can be used to find early signs of spinal cord compression before you have any symptoms.
Who can enter
You may be able to enter this trial if
- You have prostate cancer that has spread to your spine and at least 1 area of spread can be seen on a bone scan
- You have a PSA of at least 100 ng/ml
- Your PSA is continuing to rise after having hormone therapy or having your testicles removed (orchidectomy)
- You are well enough to be up and about for at least half the day (performance status 0, 1 or 2)
You cannot enter this trial if
- Your cancer has spread to your brain
- You are taking daily painkillers for back pain caused by your cancer spread
- You already have spinal cord compression or any other nerve damage
- You have had radiotherapy or surgery to treat or prevent spinal cord compression – if you had radiotherapy to relieve pain in your spine caused by your cancer spread and now have no symptoms you may take part in this trial
- You have had an MRI scan of your spine in the past year
- You have had a CT scan or PET-CT scan of your chest or tummy (abdomen) in the past 6 months
- You have had another cancer in the past 5 years apart from basal cell carcinoma and early bladder cancer that is not likely to spread (low grade)
- You are not able to have an MRI scan because for example you have a pacemaker or other metal in your body, or you cannot lie flat for at least 1 hour
This is a phase 3 trial. It will recruit 541 men. It is a randomised trial. The people taking part are put into 1 of 2 groups by a computer. Neither you nor your doctor will be able to decide which group you are in.
The men in group 1 will continue to be seen as usual. If you develop signs or symptoms of spinal cord compression you will receive treatment.
The men in group 2 will have a MRI scan. If this shows early signs of spinal cord compression you will have treatment. You then have a MRI scan every 6 months. If the scan doesn’t show signs of spinal cord compression you will see your doctor as usual.
The trial team will ask you to fill out a questionnaire when you agree to take part in this trial and then every 3 months for 3 years. The questionnaire will ask about side effects and how you’ve been feeling. This is called a quality of life study.
You see the doctor to have some tests before taking part in this trial. These tests include
- A physical examination
- Blood tests
- PSA test
After agreeing to take part, the men in group 2 will have a MRI scan.
You see the doctor every 3 months for 2 years and then every 6 months for a year.
