Ultrasound Screening for Early Detection of Breast Cancer in Elderly Women: A Mixed Cluster-Individual RCT
A Multicenter, Open-label, Mixed Cluster-Individual Randomized Controlled Study on the Efficacy of Breast Cancer Ultrasound Screening
Studieoversikt
Status
Intervensjon / Behandling
Detaljert beskrivelse
This is a multicenter, open-label, mixed cluster-individual randomized controlled trial conducted in Jiangsu Province, China. A total of 82,440 elderly women aged 65-80 years will be enrolled and assigned to either the ultrasound active screening group or the routine health management group. Communities with limited screening capacity will be randomized as clusters, while communities with individual screening conditions will randomize participants individually.
The primary endpoint is the absolute difference in the diagnosis rate of early-stage breast cancer between the two groups within 2 years of follow-up. In pilot communities of the screening group, an ultrasound AI system will be deployed synchronously to verify its diagnostic performance, homogenization effect on primary care physicians, and health economic value. All clinical diagnosis and endpoint adjudication are based on manual ultrasound reports; AI results are only used for retrospective scientific research and do not interfere with clinical decision-making.

Våpen og intervensjoner
Deltakergruppe / Arm |
Intervensjon / Behandling |
|---|---|
|
Eksperimentell: Ultrasound Active Screening Group
Participants receive one standardized breast ultrasound examination performed by certified primary care physicians during annual health check-ups.
In selected pilot communities, an ultrasound AI system is deployed synchronously for image data collection and retrospective scientific analysis only; AI results do not affect clinical diagnosis or report issuance.
|
Retrospective AI image analysis for research use only, not involved in clinical decision-making.
|
|
Ingen inngripen: Routine Health Management Group
Participants receive conventional community health management and annual physical examination according to local routine practice, without study-specific breast ultrasound screening.
