A study looking at high intensity focused ultrasound to treat pain from cancer spread to the bones
Coronavirus and cancer
We know it’s a worrying time for people with cancer, we have information to help. If you have symptoms of cancer contact your doctor.
This study looked at high intensity focused ultrasound (HIFU) as a treatment to relieve pain from cancer that had spread to the bones.
This study was open for people to join between May 2012 and July 2016. The results were published in 2018.
More about this trial
HIFU uses high frequency sound waves. It delivers a strong focused beam to a point on tissue. This causes heat and kills the tissue by burning it.
In this study researchers looked at giving HIFU guided by an MRI scan. They used the Philips Sonalleve MR-HIFU system.
They wanted to see:
- how useful HIFU was for relieving pain by burning the nerve endings on the bone surface next to a secondary bone cancer
- if the treatment caused any side effects
- how the treatment affected day to day life
Summary of results
The study team found that the MR-HIFU system:
- helped with the bone pain
quality of life
- improved day to day living
About this study
20 people had their bone pain treated using the MR-HIFU guided system. They filled in detailed questionnaires before having treatment and then after treatment at:
- 7 days
- 14 days
- 30 days
- 60 days
- 90 days
The questions asked about:
- their symptoms
- their daily activities
- how they were feeling
- their pain
Of the 20 people, 18 people filled in the questionnaires before treatment and at least 2 other times during the study.
The team compared people who had experienced a reduction in their pain and those who had not.
At 30 days the team found for people who had pain relief there was also significant improvement in their:
- physical activities
- feeling of being sick
- emotional state
And for people who had no overall pain relief there was no change in their quality of life.
The study team concluded that the MR-HIFU guided system helped treat bone pain caused by cancer spread. And this also increased the person’s quality of life.
They say that MR guided HIFU should be considered for people who have bone pain caused by cancer spread that is in one area (localised) and have a poor quality of life.
