Led by Dr. Emily Conant from the University of Pennsylvania Health System, the group sought to examine whether improved screening performance from combining DBT with digital mammography was consistent over consecutive years. To do this, the researchers compared performance metrics from three years of DBT screening, which included more than 33,000 women. They tracked recall rates, cancer detection rates, positive predictive values, biopsy rates, and interval cancer rates.
Conant and colleagues observed the following:
The data demonstrate that DBT screening outcomes are sustainable over time and, in fact, continue to improve, the researchers concluded.
