A trial looking at reducing further operations after breast conserving surgery

Cancer type:

Breast cancer

Status:

Open

Phase:

Other

This trial is looking at whether a new device called a MarginProbe can reduce the number of operations women need after breast conserving surgery. The MarginProbe measures the edges (the margins) of any tissue removed during surgery to make sure they are clear of cancer cells. 

More about this trial

In breast conserving surgery the surgeon takes away just the cancer and a border of healthy tissue all around it. They leave behind as much healthy breast tissue as possible. 

The surgeon uses various ways to make sure that they have removed the cancer. As well as checking and feeling the breast tissue they can use scans.

Your surgeon sends the breast tissue they have removed to a pathologist Open a glossary item for examination under a microscope. The pathologist checks for cancer cells in the margins around the tissue. You may need more surgery if there was no clear margin of tissue around the lump or area of cancer.

In this trial doctors are going to compare 2 groups. One group has the standard breast conserving surgery. In the other group the surgeon will use the MarginProbe. 

The aim of the trial is to see if the MarginProbe reduces the amount of surgery women need to have after breast conserving surgery.

Trial design

The researchers need around 470 women to take part in this trial. 

It is a randomised trial. You are put into 1 of 2 treatment groups by computer. Neither you nor your doctor can choose which group you are in. 

You will be put into one of the treatment groups after you are in theatre for your surgery. You will not be told which group you are in. 

  • One group has standard breast conserving surgery
  • The other group has breast conserving surgery and the MarginProbe.

Most women have their surgery as a day case. 

Quality of life
You’ll be asked to complete some questionnaires

  • before surgery
  • 1, 3 and 9 months after your surgery 

These will ask questions about your quality of life and how your breast looks (cosmetic outcomes).

Photographic measurements
The researchers also need to take some photographic measurements of your breast before your surgery, if you haven’t already had them taken. 

You’ll also have these done again 9 months after your surgery. 

Hospital visits

You go to hospital to have your surgery. 

2 weeks after your surgery you have an appointment. At this appointment the surgeon will let you know if the breast tissue margins were clear and whether you need to have any further surgery. 

As part of your routine care you will have regular check ups with your doctor. They will explain how often they need to see you.

Side effects

Women in the group using the MarginProbe may have extra breast tissue removed. But they may not need to go on to have any extra surgery.
