For analysis, the closest margins of the lumpectomies and excisional biopsies were stratified into the groups: positive, less than 1 mm, 1 to 2 mm, and greater than 2 mm.
Within this training set, application of this algorithm to the 731 lumpectomies would have selected a group of 178 lumpectomies to achieve a negative margin rate of 97.
The doctors who conducted this survey found that doctors recommended mastectomies to 45% of women who could have been treated successfully and safely with lumpectomies.
We have an excellent rate of getting clear margins after lumpectomies as well as a high rate of keeping patients from having mastectomies,'' Senofsky added.
The system is also designed to treat patients with medium or large breast tumors, and will shrink (downstage) the tumors sufficiently to allow breast conserving lumpectomies to be performed instead of complete mastectomies.
The researchers also examined 16 breast tumors removed during mastectomies or lumpectomies.
