A trial looking at laser therapy for early stage breast cancer (BR-002)
This trial looked at a type of laser therapy called Novilase to treat early breast cancer that had not spread.
More about this trial
Doctors usually treat breast cancer that has not spread with surgery. They sometimes also use radiotherapy and other treatments such as hormone therapy. These all help reduce the risk of the cancer coming back.
In this trial, researchers looked at a technique called laser ablation to kill breast cancer cells. It was for people with early stage breast cancer. The research team hope that laser treatment could be a good alternative to surgery.
The aims of this trial were to see:
- if laser ablation could be a useful treatment for early breast cancer
- how laser ablation affects the appearance of the breast
- how quickly people recover after treatment
Summary of results
The research team found that laser treatment may be a good treatment option for early stage breast cancer in the future.
This trial was open for people to join between 2012 and 2015, and the team published the results in 2018.
About this trial
Everyone in this trial had a single area of breast cancer that measured 2cm or less. They had not had any treatment for their breast cancer.
As part of the trial they had:
- an ultrasound scan, an MRI scan and a mammogram before treatment
- laser treatment
- another ultrasound, MRI scan and mammogram 4 weeks later
- an operation to check for, and remove, any signs of breast cancer
The doctor put a small probe with a laser fibre through the skin and into the area of cancer. They used ultrasound to make sure the probe was in the right place.
Next they placed a second probe through the skin near the laser probe. This one had several temperature sensors on it and was used to monitor how the treatment was going.
They then heated the end of the laser fibre until the cancer cells at the edge of the area being treated reached a high enough temperature to kill them. This is either 60 degrees Celsius, or 51 degrees Celsius for at least 2 minutes.
61 people joined this trial and they all had laser treatment and then an operation 4 weeks later. The laser treatment took between 14 and 36 minutes.
The research team looked at the results for everyone taking part. They showed that 51 out of 61 people (84%) had no signs of cancer after laser treatment.
They then looked at people who had a smaller area of cancer to begin with (1.5cm or less). They found there was no sign of cancer in 46 out of 47 people (98%).
The doctors found the MRI results were the same as the results from laboratory analysis after surgery for 52 people (87%). But they were different in 8 people (13%) - a false positive or a false negative result. One person didn’t have an MRI scan after laser treatment.
- 47 people had no signs of cancer on their MRI or on laboratory analysis
- 5 people had signs of cancer on their MRI and on laboratory analysis
- 4 people had signs of cancer on their MRI but not on laboratory analysis
- 4 people had no signs cancer on their MRI but did on laboratory analysis
Quality of life
The people taking part filled out quality of life questionnaires before and after they had laser treatment. The questionnaires asked them about things such as pain, satisfaction with the treatment and how their breast looked after treatment (the cosmetic result).
The results showed that:
- most people (97%) were satisfied with the treatment and the cosmetic result 4 weeks afterwards
- the average maximum level of pain during laser treatment was 4.2 out of 10
- nearly 8 out of 10 people (78%) were able to return to their usual day to day activities straight away
- people’s quality of life scores were better than for some other breast cancer treatments
- people had less fatigue, pain and insomnia than those who’d had surgery to remove a breast lump (a lumpectomy)
No one taking part had any severe side effects. A small number of people had short term side effects such as mild pain, bruising or a lump or blister where they’d had laser treatment.
The research team concluded that laser ablation treatment could be a possible alternative to surgery for early stage breast cancer. They suggest more trials are done to find out more about it.
They recommend doing a trial where people don’t automatically go on to have surgery afterwards. This would give more information about how well laser treatment works long term.
