Innovation in Mammography: Tomosynthesis Pathways (IMPETO)
The study aims at evaluating the introduction of tomosynthesis in mammography screening, analyzing the benefits, disadvantages and feasibility in current clinical practice.
It involves women aged 45-46 that will be divided, by drawing lots, into two groups: one group will do the 2D digital mammography (control group), while the other group (intervention group) will do tomosynthesis. In the intervention group the 2D two-dimensional mammography will be reconstructed starting from tomosynthesis without exposing women to other radiation.

Detailed Description
The IMPETO trial is a population-based, multicentre, randomised trial aimed at evaluating the clinical accuracy of Digital Breast Tomosynthesis (DBT) in adjunct to synthetic mammograms (sDM) compared to standard two-dimensional digital mammography alone (2D) in a screening programme.
45-46 year-old women resident in the screening centre catchment area of Florence and South-Est Local Health Unit are invited to attend for mammography screening and asked for informed consent to be included in the study. Women are then randomly allocated either to an usual care group (2D mammography) or to the intervention group. In the intervention group, DBT combined with sDM is proposed in order to reduce radiation exposure. The next year women of both groups will be invited to attend the usual screening examination (2D mammography). The enrolment will last 12-18 months; the whole study 36 months. The estimated sample size is 6000 women, 3000 per arm. Data will be pooled with the trial "Screening for Breast Cancer With Digital Breast Tomosynthesis", ClinicalTrials.gov Identifier: NCT02698202.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: 2D mammography
45-46 years old women are invited to attend the usual screening examination (2D mammography).
The next year they will be invited to make a 2D mammography, according to screening protocol.
|
2D mammography is a X-ray examinations used to detect breast cancer in the screening programme.
|
Experimental: Tomosynthesis
45-46 years old women are invited to attend the Digital Breast Tomosynthesis (DBT) in adjunct to synthetic mammograms (sDM).
The next year they will be invited to make a 2D mammography, according to screening protocol.
|
DBT is a x-ray examination that allows to visualize the breast on 3 planes (3D) and therefore to help to see lesions hardly visible to mammography due to the overlap of glandular tissue.
