Clinical Trial Summary

Patients who are diagnosed with breast cancer will have surgery to remove the tumour. Where this is a local excision not mastectomy, the tissue removed is sent for x-ray imaging to assess that the abnormality has been removed and give an estimation of the distance from lesion to specimen edge. This allows the surgeon to decide whether to remove more tissue or not at the time. This study is designed to compare whether more accurate information about lesion to margin measurement can be obtained using 3 dimensional tomosynthesis imaging compared to 2 dimensional conventional digital imaging which is the type of imaging currently used. This has the potential to prevent some patients requiring a second operation to remove more tissue if the margins of the specimen are still involved with tumour.

The study involves x-raying the specimen under both conditions when it arrives from theatre. Only the 2D image will be reviewed at the time as is current practice. The 3D image will be reviewed later and the measurements for lesion to specimen margin compared. The lesion to margin measurement as recorded by the pathologist will be taken as the 'gold standard' and the imaging measurements will also be compared to that.

In theory, the use of 3D tomosynthesis should allow more accurate lesion to margin measurement because 3D can provide better visualisation of the lesion edges by removing the effect of superimposed tissue.

The hypothesis states that the use of 3 dimensional tomosynthesis imaging should provide better lesion visualisation compared to 2 dimensional conventional digital imaging thus allowing more accurate lesion to margin measurement.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
