简要总结
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.
详细描述
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. UBT Srl is a partner of a Consortium which comprises (in addition to UBT): Toscana Life Sciences Foundation (Italy); London South Bank University (UK); ELAROS 24/7 Limited (UK); Servicio De Salud De Castilla La Mancha (Spain); Scuola IMT Alti Studi Lucca (Italy); EVITA - Cancro Hereditário (Portugal).

研究组 & 干预措施
Single Arm
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.
干预措施: MammoWave (Device)
结局指标
主要结局
MammoWave® sensitivity
时间窗: 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
时间窗: During the procedure
MammoWave® specificity (percentage of 'true negative' results) while using an optimized algorithm.
次要结局
- Agreement between different evaluator (i.e. local versus central)(During the baseline)
- Positive-predictive value(During the baseline)
- BC detection rates of each by histological type and size of the BC and BI-RADS classification, also by breast density(During the baseline)
- Detection rates by type of lesion(During the baseline)
- Recall rate(During the baseline)
- Program screening rate(During the baseline)
- MammoWave® sensitivity and specificity after retrospective AI adjustment using the data at the end of the study(During the baseline)
- Volunteers' satisfaction questionnaire(During the baseline)
