Is 3D Mammography more effective in detecting breast cancer?


The Ottawa Hospital Breast Health Centre and Ottawa Integrative Cancer Centre collaborate on clinical trial for breast cancer screening with digital breast tomosynthesis.

Researchers from The Ottawa Hospital Breast Health Centre and the Ottawa Integrative Cancer Centre (OICC) have opened the Ottawa site of the Lead-In to the Tomosynthesis Mammographic Imaging Screening Trial (TMIST). The Breast Health Centre is one of three clinical trial sites to launch the Lead-In in Canada. It is expected that shortly this trial will be integrated into a larger U.S./Canada TMIST, managed by the ECOG-ACRIN Cooperative Clinical Trials Group.

“Tomosynthesis is the most advanced and exciting technology for mammography,” said Dr. Jean Seely, Head of Breast Imaging at the Breast Health Centre, associate professor at the University of Ottawa and lead investigator of TMIST Lead-In in Ottawa.  “When the full study begins, it will be the largest and most important study to evaluate both 3D and 2D mammography technology together. Outcomes of the study will allow us to decide how we move forward from 2D to 3D screening.  Our goal is to improve on ways to detect important cancers as early as possible in order to save lives.”

“We are pleased to collaborate and help fund this critical trial,” said Dugald Seely, naturopathic doctor, Executive Director of the OICC, and co-investigator of TMIST in Ottawa. “Imaging and mammography are stressful events.  The OICC is committed to supporting women so that they receive the best diagnostic technology, limiting unnecessary anxiety and ultimately reducing the burden of disease. The screening program is potentially revolutionary and we hope will be more accurate in correctly finding breast cancers that may not otherwise be diagnosed.”
