Abstract

FEBLES, Gustavo; BALBIANI, Cristina  and  VAZQUEZ, Graciela. The impact of integrating breast tomosynthesis in a Breast Diagnostic Center. Rev. Méd. Urug. [online]. 2021, vol.37, n.3, e205.  Epub Sep 01, 2021. ISSN 0303-3295.  https://doi.org/10.29193/rmu.37.3.5.

Introduction:

significant technological progress has been made in the history of mammography. Recently, direct digital mammography plus tomosynthesis arrived and improved breast cancer screening.

Objective:

to evaluate the effects of new technology in the performance of mammography, at the Breast Diagnostic Service of the British Hospital.

Method:

mammography performance during 2019- 2020 was compared to that between 2010 and 2018.

In 2019 the previous tehcnology was substituted by a direct digital mammogram with tomosynthesis, Hologic, Selenia Dimensions model.

Results:

10.725 mammographies were done in 2019-2020. Cancer was detected in 84 cases and the cancer detection rate was 8 per 1000 persons. PPV was 35%.

45.438 mammographies were done in 2010-2018. Cancer was detected in 229 cases and the cancer detection rate was 5 per 1.000 persons. PPV was 40%.

As to images, it is worth pointing out an increase in microcalcifications between 2019 and 2020, when they grew from 7% of cases to 19% of cases and distortions increased from 11% to 13%.

DCIS was 4 times greater in 2019-2020 when compare to the previous period of time (17% of all detected cases).

Conclusions:

the integration of tomosynthesis increased 60% the cancer detection rate and the DCIS was 4 times greater.
