Comparison of breast cancers detected in the Verona screening program following transition to digital breast tomosynthesis screening with cancers detected at digital mammography screening.

Abstract

The Verona population-based breast cancer (BC) screening program provides biennial mammography to women aged 50–69 years. Based on emerging evidence of enhanced detection, the program transitioned to digital breast tomosynthesis (DBT) screening.

This is a prospective pilot evaluation of DBT with synthesised 2D mammography screening implemented during April 2015–March 2017; the rate and characteristics of cancers detected at DBT screening were compared with those detected at the preceding digital mammography (DM) screening round (April 2013–March 2015) in the same screening program. Distribution of imaging and tumour characteristics were compared.
