This study done on surgical specimens demonstrates as DBT showed a higher DY than DM in malignant lesion detection.
DBT recognized a greater number of cancers compared to DM.
DBT recognized 11 lesions not seen with DM.
on the contrary,
recognized 5 lesions not showed by DBT.
Both techniques missed 4 lesions,
that were 2 small (< 10 mm) IDC,
a DCIS and a IDC + DCIS with a mean diameter of 16.2 mm.
DBT showed also a statistically significant higher detectability score,
that is the reader’s subjective impression of visibility of the lesion.
In fact for the 47 lesions recognized by both techniques,
the detection score of DBT given by the readers,
This means that with DBT the readers were more confident in seeing the lesions against the fibro-glandular tissue, than DM.
With DBT the margins of lesions were better seen and judge as fully visible in a greater number of cases compared to DM.
DBT can become a new tool in evaluating breast surgical specimens,
thanks to better lesions detection.
Moreover DBT can help the reader to became more confident in lesion recognition and definition of margins.
For this clinical application other study were required in order to evaluate the ability of DBT in recognized lesions margins,
in comparison to DM.
The main limitation of our study is the small sample size.
Moreover we evaluated not only surgical specimens obtained by BCS,
but also mastectomy-specimens.
For these reasons we are collecting new cases and in particular BCS-specimens.
