NCT07214051
The United States Preventive Services Task Force (USPSTF) recommends regular screenings for breast, cervical, and colorectal cancer. The COVID-19 pandemic has disrupted health screening practices, leading to a decrease in cancer screenings among the United States including Puerto Rico. This has been attributed to unwillingness, distrust, and insecurity related to accessing healthcare services. To overcome these challenges, a collaboration between PR-CEAL's Community Outreach Engagement Group (COEG), academic researchers, healthcare institutions, and community-based organizations proposed to engage in different community activities throughout the island. In these events, investigators conducted a single blinded community-based Randomized Clinical Trial (RCT) regarding cancer screening practices in women 21 through 75 years. The community-based RCT employed a mixed-method design to gain insights into the perception of health and cancer screening status of participants regarding breast, uterine (cervical), and colorectal cancer. Data was collected through in person interviews and two follow up phone calls, enabling the researchers to obtain valuable sociodemographic information, assessing cancer screening history, and identifying existing barriers. The hypothesis of this study is that implementing evidence-based intervention at community settings across Puerto Rico will have a significant positive effect on cancer screening rates among non-adherent patients. By identifying and adapting the Prevention Care Management for Cancer Screening intervention and leveraging the expertise of the National Cancer Institute, the study aimed to improve screening rates, address barriers that hinder or delay screenings, and raise awareness about the importance of early detection.
NCT07200427
Breast cancer (BC) is the most commonly diagnosed cancer in women worldwide, with early-onset cases increasing due to genetic and lifestyle factors. Traditional prevention strategies have shown limited effectiveness, creating the need for innovative approaches. The MELIORA project develops an AI-driven digital tool, the Virtual Coach (VC), to promote sustainable behaviour change in physical activity, diet, and alcohol use. Three randomized-controlled studies will be conducted: MELIORA-HEALTHY (women at risk, n=1080 in Greece, Lithuania, Spain), MELIORA-PATIENTS (women undergoing treatment, n=400 in Lithuania, Spain), and MELIORA-SURVIVORS (post-treatment survivors, n=600 in Lithuania, Spain, Sweden). Participants across diverse regions and backgrounds will be randomized to standard lifestyle advice or the same advice plus the MELIORA VC app. Each study lasts 12 months, with outcomes assessed at baseline, 6, and 12 months. The primary outcome is physical activity, with secondary outcomes including sedentary behaviour, diet, alcohol use, and quality of life. If effective, the MELIORA VC could offer a scalable, cost-effective model for BC prevention and survivorship care, providing valuable evidence to guide public health strategies.
NCT07190066
To support the development of the MELIORA digital app for the MELIORA main intervention, an initial pilot study (Data Collection Campaign, DCC) is being conducted with the three target participant groups: healthy women at increased risk of developing breast cancer (BC), BC patients, and BC survivors across the four intervention countries (Spain, Greece, Lithuania, Sweden). The planned sample size for each group is 156 healthy women at risk (defined as not meeting recommendations for a healthy lifestyle), 58 BC patients, and 86 BC survivors. Each participant is asked to test and evaluate a preliminary version of the MELIORA app over a 14-day period. The DCC takes place in the early stages of the project, as part of the intervention development phase, to inform the technical refinement and preliminary evaluation of the MELIORA digital app.

This study aims to to improve physical activity and metabolic outcomes for breast cancer prevention in South Asian Indian immigrant women.
NCT02028221
Overweight and obesity are well established risk factors for breast cancer that develop after menopause. The increased postmenopausal breast cancer risk in women who are overweight or obese is likely to be attributed to multiple metabolic disturbances. Metformin is a commonly used medication in diabetics to stabilize blood sugar. Association studies and laboratory studies have shown its potential to reduce the risk for development of cancer, including breast cancer. Recent pilot clinical studies in breast cancer patients suggest that metformin may only be effective in overweight or obese women with metabolic disturbances. We propose to conduct a clinical study of metformin in overweight or obese premenopausal women with metabolic disturbances. Study participants will be randomly assigned to receive metformin or placebo for 12 months. The study will evaluate whether metformin can result in favorable changes in risk features that have been associated with increased breast cancer risk. The risk features that will be examined in our study include breast density, certain proteins and hormones, products of body metabolism, and body weight and composition. The study should help determine the potential breast cancer preventive activity of metformin in a growing population at risk for multiple diseases.

This study aims to prove whether antler disk extract can be put into clinical practice to prevent breast precancerous lesions from developing into cancer.
NCT01299623
We will develop and evaluate a community-based approach for disseminating comparative effective reviews (CERs) about breast cancer prevention to African American women. The specific aims of our research, as shown below, will target this population because of persistent disparities in breast cancer morbidity and mortality among this population. Our primary aims are: 1. To evaluate uptake of a community-based strategy for disseminating CERs about breast cancer prevention to African American women based on sociodemographic characteristics, beliefs about medical research, and medical history. We predict that participation in a community forum will be higher among women with greater socioeconomic resources, those who have a family history of breast cancer, and women who have more positive beliefs about research. 2. To evaluate the impact of evidential versus non-evidential content about breast cancer prevention on psychological and behavioral outcomes that include: knowledge of breast cancer risk factors and prevention strategies, communication with individuals in their social and medical network, and distrust of medical research. We predict that women who receive evidential content that is specific for African American women will report greater knowledge about breast cancer risk factors and prevention strategies, will be more likely to discuss breast cancer prevention strategies with individuals in their social and medical network, and will report greater reductions in distrust of medical research compared to those who receive non-evidential content.
