ACRIN TRIALS PROVE DIGITAL MAMMOGRAPHY TO BE MORE EFFECTIVE

The American College of Radiology Imaging Network (ACRIN) has completed the largest cancer screening trial in history. The Digital Mammography Imaging Screening Trial tested more than 49,000 women over a four year period to determine whether digital mammography can detect breast cancer as well or better than the gold standard of conventional screen-film mammography.

A summary of the results ----

Digital mammography was significantly better in screening women who fit any of these three categories:

Under age 50 (all breast types)
Any age group with very dense or extremely dense breasts
Pre-or peri-menopausal women at any age.

65% of all women fit into these 3 categories

FFDM (Digital mammography) found cancers that matter:

Lesions detected by digital mammography and missed by film in women in all three categories included many invasive cancers and medium and high grade in situ lesions.

Sensitivity for FFDM in dense breast is higher:

The sensitivity for women with dense breasts was only 55% for film mammography while the sensitivity for digital was 70%.

Overall Message:

The trial results suggest that women in the subgroups above are likely to benefit from earlier detection of their breast cancers if they have a digital mammography instead of film mammography.
