The role of tomosynthesis in intraoperative specimen evaluation.
To investigate the contribution of breast tomosynthesis to intraoperative specimen evaluation in subjects with breast cancer. Approval was obtained from the hospital ethics committee. Specimen mammography, tomosynthesis, and, if available, ultrasonography images were retrospectively assessed for 208 women who had undergone conservative surgery at our hospital between January 2013 and April 2016 after being diagnosed with breast cancer. The success of mammography, tomosynthesis, and ultrasonography in lesion detection and characterization was evaluated. Of 208 lesions, 142 (68.3%) and 198 (95.2%) were detected by mammography and tomosynthesis, respectively. All lesions were detected in 150 subjects undergoing ultrasonography (124 dense breasts, 26 fatty breasts). In 84 women who had fatty breasts, all lesions were detected both by mammography and by tomosynthesis. In 124 women with dense breasts, lesions were detected by mammography in 59 (48%) and in 114 (92%) by tomosynthesis. The success of tomosynthesis in lesion detection was found to be markedly higher than mammography (P = .00). In conclusion, tomosynthesis contributed to mammography in specimen evaluation in a total of 101 subjects. The success of tomosynthesis in lesion detection and characterization during intraoperative specimen evaluation is higher than mammography. In daily practice, ultrasonography is performed for lesions which cannot be evaluated by specimen mammography due to dense parenchymal pattern. Tomosynthesis may reduce the need for and the time and workforce allocated to specimen ultrasonography in an important group of subjects.
