The Dynamic Optical Breast Imaging in the Preoperative Workflow of Women with Suspicious or Malignant Breast Lesions : Development of a New Comprehensive Score

Abstract EN

Purpose.

To determine the diagnostic accuracy of DOBIComfortScan in patients with Breast Imaging Reporting suspect breast lesions (BI-RADS) 4-5 breast lesions.

Materials and Methods.

One-hundred and thirteen patients underwent DOBIComfortScan examination before surgery.

Twelve parameters were taken into consideration to define DOBI findings.

Results.

Twenty-seven radical mastectomies, 47 quadrantectomies and 39 wide excisions, were performed.

Overall, 65 invasive cancer, 9 in situ carcinoma and 39 nonmalignant lesions, were observed.

Ten out of 12 considered parameters resulted significantly in association with histology at discriminant analysis.

A summation score of 30.5 resulted to be the best cut off at ROC analysis, giving a sensitivity and specificity of 80% and 87%, respectively, and a positive predictive value of 92.2%.

Finally the following DOBI-BI-RADS model was developed: malignant B5≥38 score); possibly malignant (B4=25-37 score); benign but the possibility of malignancy cannot be excluded (B3=20-24 score); benign (B2<20 score).

Conclusion.

definition of other parameters permits to improve the accuracy of this procedure.

Further studies are warranted to define the potential role of DOBIComfortScan in breast cancer imaging.
