A Clinical Investigation to Evaluate Microwave Imaging Via MammoWave® in a Population-based Screening Program for Early Breast Cancer Detection
- Conditions
- Women's Health: Neoplasm of Breast
- Interventions
- Device: MammoWave
- Registration Number
- NCT06291896
- Lead Sponsor
- Umbria Bioengineering Technologies
- Brief Summary
This is an open, multicentric, interventional, prospective, non-randomized clinical investigation. The first aim of the study is to confirm that MammoWave reaches sensitivity\>75% and specificity\>90% in breast cancer (BC) detection on 10.000 volunteers undergoing regular screening programs.
- Detailed Description
MammoWave is a non-CE marked device that uses low-power (1mW) microwaves (1-9 GHz) instead of ionizing radiation (X-ray) for BC screening. MammoWave uses safe low-power radio frequency signals in the microwave band; it is a Class IIa medical device (non-invasive device). The previous generation of MammoWave had obtained the CE mark; in this investigation, the device contains the same hardware and will be used with the same acquisition method as the CE marked device, but additional data processing software will be used.
The 10,000 volunteers undergoing conventional breast screening examination will also undergo the MammoWave exam. The MammoWave results (WSF: breast With Suspicious Finding,i.e. with suspicious lesion, or NSF: No Suspicious Finding, i.e. breast without lesion or with low suspicious lesion) will be checked against the Reference Standard, to be intended as the output of conventional breast examination path (i.e., screening mammogram, integrated with other radiological/histological output when deemed necessary by the responsible Investigator in each site). Reference Standard may be BC+ for the histology-confirmed breast cancer (BI-RADS 6); BC- otherwise (BI-RADS 1, 2, 3).
(NOTE: BIRADS 4 and 5 are only image suspicion criteria: when a biopsy is performed, BIRADS are transformed in 6 (BC+) or 1,2 and 3 (BC-))
This clinical trial is performed within MammoScreen project \[1\] awarded in the context of HORIZON-MISS-2021-CANCER-02-01.

Study & Design

- INTERVENTIONAL
- Study Design
- SINGLE_GROUP
- Arm && Interventions
Group Intervention Description Single Arm MammoWave All participants perform: conventional breast examination path (i.e., screening mammogram, integrated with other radiological/histological output when deemed necessary by the responsible Investigator in each site) AND MammoWave exam.
- Primary Outcome Measures
Name Time Method MammoWave® sensitivity During the procedure MammoWave® sensitivity (percentage of 'true positive' results) while using an optimized classification algorithm. The Reference Standard is intended as the output of conventional breast examination path (i.e. screening mammogram, integrated with other radiological/histological output when deemed necessary by the responsible Investigator). Reference Standard may be: BC+ for the histology-confirmed and classified as BI-RADS 1,2 or 3.
MammoWave® specificity During the procedure MammoWave® specificity (percentage of 'true negative' results) while using an optimized algorithm.
- Secondary Outcome Measures
Name Time Method Agreement between different evaluator (i.e. local versus central) During the baseline Evaluation of the reproducibility of results comparing the lectures performed at the study centers and the centralized lectures
Positive-predictive value During the baseline Evaluation of MammoWave positive predictive value (for the biopsies performed), also by breast density (according to BI-RADS ACR classification assigned by the radiologist), and comparison with the other standard screening and diagnostic modalities.
BC detection rates of each by histological type and size of the BC and BI-RADS classification, also by breast density During the baseline BC detection rates of each by histological type and size of the BC and BI-RADS classification, also by breast density
Detection rates by type of lesion During the baseline Evaluation of the detection rates (sensitivity) according to the type of radiological finding (microcalcification, mass, asymmetry or architectural distortion group), also by breast density (according to BI-RADS ACR classification assigned by the radiologist), and comparison with the other standard screening and diagnostic modalities.
Recall rate During the baseline Evaluation of MammoWave recalls, also by breast density (according to BI-RADS ACR classification assigned by the radiologist), and comparison with the other standard screening and diagnostic modalities.
Program screening rate During the baseline Program screening rate, calculated as the proportion of women diagnosed with BC in the study population
MammoWave® sensitivity and specificity after retrospective AI adjustment using the data at the end of the study During the baseline Evaluation of the improvement in both sensitivity and specificity when retrospectively using AI algorithms for the evaluation of MammoWave® data after its further optimization with all data collected in the participants included in the study.
Volunteers' satisfaction questionnaire During the baseline Volunteers' satisfaction through a properly designed questionnaire collecting women's issues and plus during the exam with MammoWave® in the language spoken by the women
