Digital Breast Tomosynthesis and Synthetic 2D Mammography versus Digital Mammography: Evaluation in a Population-based Screening Program.
Purpose To compare the performance of digital breast tomo synthesis ( DBT ) and two-dimensional synthetic mammography ( SM ) with that of digital mammography ( DM ) in a population -based mammographic screening program . Material s and Methods In this prospect i ve cohort study , data from 37 185 women screened with DBT and SM and from 61 742 women screened with DM as part of a population -based screening program in 2014 and 2015 were included . Early performance measures , including recall rate due to abnormal mammographic findings , rate of screen-detected breast cancer , positive predictive value of recall , positive predictive value of needle biopsy , histopathologic type , tumor size , tumor grade , lymph node involvement , hormonal status , Ki-67 level , and human epidermal growth factor receptor 2 status were compared in women who underwent DBT and SM screening  and in those who underwent DM screening  by using χ2 tests , two- sample unpaired t tests , and tests of proportions . Results Recall rates were 3.4 % for DBT and SM screening and 3.3 % for DM screening ( P = .563 ) . DBT and SM screening showed a significantly higher rate of screen-detected cancer compared with DM screening ( 9.4 vs 6.1 cancers per 1000 patients screened , respectively ; P < .001 ) . The rate of detection of tumors 10 mm or smaller was 3.2 per 1000 patients screened with DBT and SM and 1.8 per 1000 patients screened with DM ( P < .001 ) , and the rate of grade 1 tumors was 3.3 per 1000 patients screened with DBT and SM versus 1.4 per 1000 patients screened with DM ( P < .001 ) . On the basis of immunohistochemical analyses , rates of lymph node involvement and tumor subtypes did not differ between women who underwent DBT and SM screening and those who underwent DM screening . Conclusion DBT and SM screening increased the detection rate of histologically favorable tumors compared with that attained with DM screening . © RSNA , 2018 Online supplemental material is available for this article
