NCT07075679
A randomized prospective study comparing the evaluation of mammography images in a breast cancer screening programme by a single radiologist with AI support versus standard double reading by two radiologists without AI support.
NCT07472036
The goal of this trial is to learn whether a culturally and linguistically tailored reminder letter can increase participation in the Flemish Breast Cancer Screening Program among women who previously did not attend screening. The study also examines whether the effect differs between socioeconomic groups. The main questions it aims to answer are: * Does a tailored reminder letter increase participation among previous non-attenders? * Does the effect differ between women with lower and higher socioeconomic status? Researchers compare two groups: * Intervention group: receive the standard invitation letter plus an additional tailored reminder letter. * Control group: receive the standard invitation letter only. Participation in screening within 40 days of the invitation is measured using the program's registry. Participants are women aged 50-69 years who had previously been invited but had never attended screening. The reminder letter is sent as part of routine screening communication, and no additional medical procedures are involved.
NCT07374796
The purpose of this research study is to test a new process for diagnosing breast cancer by examining changes to your DNA that can be detected from a blood test. The information we learn by doing this study could potentially help people in the future. Participants in this study will have blood samples collected, have their medical records reviewed by study personnel and fill out questionnaires at different time points during the study. Blood sample collection will occur during normal routine clinic visits. Participation in this study will last approximately 5 years.
NCT07355569
This study has been designed as a randomized controlled trial including women invited to a national screening program for breast cancer in Norway, BreastScreen Norway in 2025. The program invites women aged 50-69 to biennial screening mammography. The study includes two substudies with the intervention of sending an SMS notification three days prior to the screening appointment in the first substudy and two days prior to the screening appointment in second study. The comparison is made between the study groups, where women are sent an SMS notification two or three days prior to their scheduled screening appointment and the control groups where women will not be sent an SMS notification about a scheduled screening appointment.
NCT07298252
This study evaluates the diagnostic performance of Carebot AI MMG, an artificial intelligence (AI)-enabled medical device for evaluating mammograms. The software analyzes standard full-field digital mammography (FFDM) images and classifies each examination as having no suspicious finding ("Low Risk"), a probably benign mass ("Medium Risk"), or a suspicious malignant mass ("High Risk"). The study is retrospective and observational. It uses anonymized mammography examinations from four screening centers, without any additional imaging or contact with patients. Three experienced breast radiologists independently read the same set of cases, and their assessments are used as the human benchmark. A histopathology-based reference standard, supplemented by radiologist consensus and follow-up information for negative cases, is used to determine whether cancer is present. The main goal is to compare the AI system with human radiologists in terms of sensitivity and specificity for detecting breast cancer, and to assess whether the AI can achieve non-inferior performance at two predefined operating points: one favoring higher sensitivity and negative predictive value (rule-out) and one favoring higher specificity and positive predictive value (rule-in).
NCT06934239
The goal of this clinical trial is to compare patient-centered outcomes when screening digital breast tomosynthesis (DBT) exams are interpreted with versus without a leading FDA-cleared artificial intelligence (AI) decision-support tool in real-world U.S. settings and to assess patients' and radiologists' perspectives on AI in medicine. The main question it aims to answer is: Does an FDA-cleared AI decision-support tool for digital tomosynthesis (DBT) improve screening outcomes in real world US clinical settings? This trial will include all interpreting radiologists and all adult patients undergoing screening mammography at any of the participating breast imaging facilities across 6 regional health systems (University of California, Los Angeles (UCLA), University of California, San Diego (UCSD), University of Washington-Seattle, University of Wisconsin-Madison, Boston Medical Center, and University of Miami) during the trial period. All screening mammograms at these facilities will be randomized to either intervention (radiologist assisted by an AI decision support tool) versus usual care (radiologist alone) to see if interpreting these mammograms with the AI tool's assistance improves patient screening outcomes. We are targeting 400,000 screening exams across the participating health systems in this trial.
NCT02620852
Most physicians still use a one-size-fits-all approach to breast screening in which all women, regardless of their personal history, family history or genetics (except BRCA carriers) are recommended to have annual mammograms starting at age 40. Mammograms benefit women by detecting cancers early when they are easier to treat, but they are not perfect. Recent news stories have discussed some of the potential harms: large numbers of positive results that cause stressful recalls for additional mammograms and biopsies. With the current screening approach, half of the women who undergo annual screening for ten years will have at least one false positive biopsy. Potentially more important are cancer diagnoses for growths that might never come to clinical attention if left alone (called "overdiagnosis"). This can lead to unnecessary treatment. Even more concerning is evidence that up to 20% of breast cancers detected today may fall into the category of "overdiagnosis." The WISDOM 1.0 study compares annual screening with a risk-based breast cancer screening schedule, based upon each woman's personal risk of breast cancer. The investigators have designed the study to be inclusive of all, so that even women who might be nervous about being randomly assigned to receive a particular type of care (a procedure that is typical in clinical studies) will still be able to participate by choosing the type of care they receive. For participants in the risk-based screening arm, each woman will receive a personal risk assessment that includes her family and medical history, breast density measurement and tests for genes (mutations and variations) linked to the development of breast cancer. Women who have the highest personal risk of developing breast cancer will receive more frequent screening, while women with a lower personal risk would receive less frequent screening. No woman will be screened less than is recommended by the USPSTF breast cancer screening guidelines. If this study is successful, women will gain a realistic understanding of their personal risk of breast cancer as well as strategies to reduce their risk, and fewer women will suffer from the anxiety of false positive mammograms and unnecessary biopsies. The investigators believe this study has the potential to transform breast cancer screening in America. Starting in Spring 2023, WISDOM's design shifted to remove the randomized option, but will continue with the preference/self-selection option for participation (WISDOM 2.0). Participants will therefore continue to choose their study arm (Personalized or Annual) rather than have the option to be randomized. This study design change was made after review of the WISDOM 1.0 data by an independent monitoring committee, which indicates that personalized screening does not cause harm. WISDOM 2.0 has also lowered the eligibility to ages 30-74. Women ages 30-39 will only be offered to join the Personalized Arm.
NCT01900821
The National Mammography Database (NMD) leverages data that radiology practices are already collecting under federal mandate by providing them with comparative information for national and regional benchmarking. Participants receive semi-annual feedback reports that include important benchmark data such as cancer detection rates, positive predictive value rates and recall rates. Participation in the NMD is free to Breast Imaging Center of Excellence (BICOE) facilities.
NCT06902935
Construct a breast cancer risk prediction model based on traditional Chinese medicine four diagnostic instruments and B-ultrasound images. Ensure that the key evaluation indicators of the model reach a high level through clinical verification, so as to contribute to accurate clinical diagnosis and treatment decision-making.
NCT02310698
Breast tumors are often detected on mammography but may be harder to see in women with dense breasts. This is why screening breast ultrasound is sometimes used as another test in women with dense breasts. Ultrasound has been shown to detect additional cancers that are not seen on regular mammography. Contrast Enhanced Digital Mammography (CEDM) is a FDA approved form of mammography. It is essentially a routine digital mammogram performed after iodine dye (the same that is used with CT scans) is injected into a vein in the arm. Like screening ultrasound, CEDM has been shown to detect breast cancers that are not seen on a regular mammogram. The purpose of this study is to compare whether CEDM or screening breast ultrasound is better at detecting cancer. Both will be done in this study and compared to one another.
NCT06500936
We carried out with a mixed-method study including a pragmatic randomized controlled trial to evaluate effectiveness of the intervention and quantitative and qualitative evaluation of the implementation from women and stakeholders' perspective. In this report, we present results of the pragmatic randomized control trial and implementation evaluation from women´s perspective guided by the Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) framework, specifically developed to assess interventions beyond efficacy across multiple public health criteria. RE-AIM framework was integrated in all stages of the research process, including conceptualization (e.g., selecting implementation processes that would be evaluated), data collection and analysis. Following Proctor´s Taxonomy of Implementation Outcomes \[34\], we also measured acceptability and appropriateness, which are essential to understand the success (or failure) of the implementation of an intervention from users' perspective. This approach is the same as we used to evaluate implementation in our previous study (The ATICA study).
NCT05268224
Investigation of a tear-based, lab-developed biological test for breast cancer, as a supplemental tool to current screening recommendations for women with dense breast tissue will explore if a tear-based biological test can be used as a support tool in the breast cancer screening protocol for women with dense breast tissue. The test was designed and validated by Namida Lab, Inc., a high complexity Clinical Laboratory Improvement Amendments (CLIA) certified lab.
NCT03517813
This is a single institution, prospective screening trial of women at high risk for developing breast cancer, enriched with women with suspicious lesions on breast MRI which have been recommended for biopsy. Primary Aim: Measure and compare the diagnostic performance of CESM, ABMR, and standard breast MRI, using the following performance measures: cancer detection rate (CDR), biopsy rate, and cancer yield of biopsy (also known as positive predictive value 3 or PPV3). Secondary Aims: 1. Compare screening performance outcome measures of sensitivity, specificity, and area under the receiver operating characteristic curve (AUC) for CESM, ABMR, and standard breast MRI. This will determine the feasibility of each modality as an alternative to standard breast MRI and provide valuable pilot data for designing a larger clinical trial to evaluate non-inferiority of either or both modalities. 2. Breast cancer characteristics (size, histologic subtype, node-positivity, AJCC stage) will be assessed in the overall cohort, and stratified by mode of detection for each modality(screen-detected versus interval).
NCT04741503
The purpose of this investigation is to conduct a feasibility study to evaluate the potential for implementing the developed decision support tool with Latina, Black, and non-Latina White women. The investigators will collect feasibility data and assess the use of the decision support tool with end-users. The aim is to determine if women using the decision support tool make more informed choices measured by knowledge, attitudes, and intentions.
NCT04057391
This study aims to characterize patient experience, satisfaction and preference for use of the QT Scanner in comparison to mammography by directly engaging women who have experience with both technologies.
NCT03046004
The aim of this study is to assess the effect of receiving information about the benefits and harms of mammography screening on informed choice, decisional conflict, intention to participate in the Early Detection of Breast Cancer Program (EDBCP), and satisfaction. The primary outcome is informed choice about breast screening (adequate knowledge, and consistency between attitudes and intentions). The sample of participants is composed by 400 women from Catalonia and the Canary Islands (Spain) who will receive their first invitation to participate in the EDBCP of the Public Health Service in a period of 2-4 months.
NCT04259866

The Avellino Breast Tomosynthesis Screening Trial is a observational population-based study that analyze souspicious findings in tomosynthesis slice images. This study is based on two years screening and tomosynthesis was analzyed by two expert breast radiologists.
NCT01267110
Breast cancer is the second most common cause of cancer death in the U.S.1 in spite of being preventable, easily detectable, and curable.2-11 Breast screening continues to be underutilized by the general population and especially by traditionally underserved minority populations. Two of the least screened minority groups are American Indians/Alaska Natives (AI/AN) and Latinas. American Indian/Alaska Native women have the poorest recorded 5-year cancer survival rates of any ethnic group and the lowest (or near-lowest) screening rates for major cancers.12 Furthermore, breast cancer is the number one cause of cancer mortality among Latina women.13 While breast cancer screening rates have increased nationally, there has been an increase in the gap in breast cancer screening utilization between individuals from minority versus majority racial/ethnic groups.
NCT00287040
The purpose of this study is to compare mammography adherence among women receiving tailored, interactive mammography interventions via DVD and telephone counseling to usual care.
