A Pragmatic Trial of Tomosynthesis vs Digital Mammography for Breast Cancer Screening (TMIST)

The Tomosynthesis Mammographic Imaging Screening Trial (TMIST or study EA1151) is a randomized breast cancer screening study. The ECOG-ACRIN Cancer Research Group opened the trial on July 6, 2017, and is currently enrolling about 165,000 women who are planning to have regular mammograms. TMIST is very important to the future of breast cancer screening because it will give us knowledge about how to move beyond our current “one size fits all” approach, where we screen most women the same way based on age-specific guidelines. The trial will help us move towards a more personalized approach that tailors mammography for each woman based on her own genetics and individual risk factors for developing breast cancer.
