Highlights

-Intraoperative specimen mammography (ISM) is a diffuse technique that allows surgeons to check specimens immediately after lumpectomy

-A novel technique is presented, consisting of ISM of the surgical specimen after vacuum sealing, with the aim of reducing tissue overlap, increasing the accuracy of imaging, and minimizing unnecessary resections.

-Vacuum ISM is feasible, cost-saving and yields similar results to those from frozen sections but without the limitations, such as prolonged operating time, high variability in sensitivity due to pathologists’ abilities, risk of compromising the histological report, and unreliability for small lumps and ductal carcinoma in situ

Intraoperative specimen mammography (ISM) is a diffuse technique that allows surgeons to check specimens immediately after lumpectomy. Although the specimen is slightly compressed, the radiological image can be distorted by tissue overlap, and this may affect the evaluation of tumor borders, resulting in an extension of the lumpectomy. As ISM may be less precise due to inadequate compression, a vacuum effect was applied to the specimen to increase the precision of margin detection.

Eighteen specimens obtained after lumpectomy for sISM, specificity was 47%, sensitivity was 67%, positive predictive value (PPV) was 20% and negative predictive value (NPV) was 88%. For vISM, specificity was 100%, sensitivity was 67%, PPV was 100% and NPV was 94%.

These data suggest that the vacuum technique is feasible, cost-saving and yields results that are similar to those from frozen sections but without the limitations, such as prolonged operating time, high variability in sensitivity due to pathologists’ abilities, risk of compromising the histological report, and unreliability for small lumps and ductal carcinoma in situ.
