A Clinical Study of Sacituzumab Tirumotecan (Sac-TMT, MK-2870) in People With Breast Cancer (MK-2870-032)

Researchers are looking for new ways to treat types of breast cancer that are both: * High-risk, which means the cancer may have a higher chance of getting worse or coming back after treatment * Early-stage, which means the cancer is in the breast or the lymph nodes around the breast The 2 types of breast cancer in this study are triple-negative breast cancer (TNBC) and hormone receptor (HR)-low positive/human epidermal growth factor receptor-2 (HER2) negative breast cancer. These cancers have zero or a low amount of a protein called HER2 and other proteins that attach to the hormones estrogen or progesterone. Sacituzumab tirumotecan (also known as sac-TMT or MK-2870), the study medicine, is a type of targeted therapy. A targeted therapy is a treatment that works to control how specific types of cancer cells grow and spread. The main goals of this study are to learn if people who receive sac-TMT, pembrolizumab, and chemotherapy: * Have fewer cancer cells found in the tumors and lymph nodes removed during surgery compared to those who receive only pembrolizumab and chemotherapy * Live longer without the cancer growing, spreading, or coming back compared to people who receive only pembrolizumab with chemotherapy

A Clinical Study of Patritumab Deruxtecan to Treat Breast Cancer (MK-1022-016)

Researchers are looking for other ways to treat breast cancer (BC) that is hormone receptor-positive and human epidermal growth factor receptor 2-negative (HR+/HER2-) and either unresectable locally advanced or metastatic. * HR positive (HR+) means the cancer cells have proteins that attach to estrogen or progesterone (hormones) which help the cancer to grow and spread * HER2 negative (HER2-) means the cancer cells have a low amount of a protein called HER2 * Unresectable locally advanced means the cancer cannot be completely removed by surgery and has spread into nearby tissue or muscles * Metastatic means the cancer has spread to other parts of the body Treatment for this type of breast cancer usually includes endocrine therapy (ET) and sometimes a second treatment. The main goal of this study is to learn if people who receive patritumab deruxtecan (also known as HER3-DXd and MK-1022) live longer overall or without the cancer growing/spreading, compared to people who receive chemotherapy or a different drug called trastuzumab deruxtecan.

A Study of Imlunestrant (LY3484356) in Premenopausal Women With Estrogen Receptor-Positive (ER+) Human Epidermal Growth Factor Receptor 2 Negative (HER2-) Early Breast Cancer

This study will include two groups of patients: Cohort 1 and Cohort 2. Cohort 1: will help researchers learn how a medicine called imlunestrant (LY3484356) affects a specific type of breast cancer. Some patients will take both imlunestrant and another treatment to suppress their ovarian function. Some will take it without ovarian suppression. Researchers will compare the effects in breast cancer cells to those of another medicine called tamoxifen. All patients in this group will be premenopausal women who have a type of early breast cancer called estrogen receptor-positive, HER2-negative. The treatment in this group will last for up to 29 days. Cohort 2: will help researchers understand how imlunestrant affects the ovaries when it is taken without ovarian suppression. Researchers will compare the effects to those of another medicine called tamoxifen. This group will also include premenopausal women with the same type of breast cancer. The treatment in this group will last for up to 6 months.

Impact of Prehabilitation and Comprehensive Follow-up in Women With Breast Cancer

Breast cancer (BC) is the most common cancer among women worldwide. Cancer treatments are associated with numerous adverse events that reduce patients' functionality and alter their clinical and molecular profiles. Physical exercise and adherence to nutritional guidelines during treatment and survivorship have been shown to improve recovery prognosis and reduce treatment-related complications. However, the specific effects of prehabilitation, defined as "the process in the cancer continuum that occurs between diagnosis and the start of treatment," remain unknown in BC. A concurrent training program and specific nutritional guidelines during this phase could reduce treatment-related adverse events and improve recovery. Similarly, including a home-based exercise program and nutritional guidelines throughout the cancer treatment continuum could enhance the benefits achieved and improve various aspects of functionality, clinical status, and quality of life. Therefore, the main aim of this randomized controlled trial is to evaluate the impact and effects of a supervised prehabilitation program (combining high-intensity concurrent training and personalized nutritional guidelines) and a supportive care intervention (home-based exercise and personalized nutritional guidelines) on functional, neuromuscular, and cardiorespiratory capacity, quality of life, body composition, and clinical and molecular outcomes in women with BC. In addition, the sustainability of the benefits achieved in the long-term care and the evolution of the outcomes assessed throughout the continuum of cancer treatments will be analyzed.

Nudging Preventive Screening Via Message Framing and Bundling

This study is a randomized controlled field experiment embedded in the medical institution Early Diagnosis Program in Chile. Participants with two exams pending (a cancer screening test and a chronic disease test for diabetes and dyslipidemia) will be randomly assigned across a 3 × 3 factorial design: three message framing conditions (Basic, Risk/Importance, Peace of Mind) crossed with three exam-type conditions (cancer screening only, chronic disease test only, or both exams). Participants with only a cancer screening pending will be assigned to the 3 framing conditions and be encouraged to get the cancer screening. In both cases, participants are assigned to each experimental arm at twice the rate of an additional arm receiving the standard message currently used by the medical institution. This standard-message arm is included for operational purposes, is not part of the pre-specified analyses, and is thus not described in the "Arms and Intervention" section (or counted for "number of arms").

Breast Cancer, Reasoning, and Activity Intervention

This phase II trial tests whether an exercise intervention works to improve cognitive function in breast cancer survivors. Many breast cancer survivors report cancer-related cognitive impairment, which this has recently become a priority in clinical research due to its dramatic impact on daily functioning, quality of life, and long-term health. Aerobic exercise has the potential to improve cognitive function and brain health in older adults and is recommended as a safe, tolerable, and accessible complementary therapy for breast cancer survivors. This study aims to understand the effects of physical activity compared with health education on memory, attention, and brain health in women with breast cancer. Study findings may help researchers design more programs that can improve memory, attention, and brain health in other women with breast cancer.

Non-Contrast Breast MRI Diagnosis and Risk Stratification Using DWI-Generated Synthetic Contrast Enhancement

This study is conducted under the ethics-approved project titled "Artificial Intelligence Solution for Simplifying the Diagnostic Workflow of Breast MRI''.The goal of this observational study is to develop an integrated breast MRI system that uses diffusion-weighted imaging (DWI) to create synthetic contrast-enhanced images. This system aims to diagnose and screen for breast cancer without the need for contrast agents, while using a generated risk score to perform imaging-based triage and risk stratification. Participants will include people aged 18 and older who require a breast MRI either for evaluation of a suspicious finding or for high-risk screening. This study seeks to answer two main questions: * Can synthetic contrast-enhanced images generated from DWI match real contrast-enhanced images in their ability to distinguish benign from malignant breast lesions? * Can the risk score derived from DWI-based synthetic images enable imaging-level risk stratification, allowing people at lower risk to avoid contrast agent injection? Researchers will compare the quality of synthetic images against real contrast-enhanced images and will recruit radiologists to assess how well these images perform for diagnostic and screening tasks. MRI data from participants undergoing breast MRI will be used to train, validate, and test this integrated system.

Acute and Long-term Cardiovascular Toxicity After Modern Radiotherapy for Breast Cancer

In Europe, breast cancer is by far the most common form of cancer diagnosed in women today, accounting for 29% of all cases. The 5-year survival rate is approximately 90%. Surgery is usually combined with radiotherapy (RT), anthracyclines, aromatase inhibitors and/or trastuzumab (Herceptin) which all have improved the life expectancy and survival in breast cancer patients. Unfortunately, RT is associated with a broad spectrum of cardiovascular diseases, which includes coronary artery disease, valvular dysfunction, congestive heart failure and stroke, and is the most common non-malignancy cause of death. During the last two decades, RT regimens for breast cancer have changed and the doses of radiation to which the heart is exposed are now potentially lower due to new and improved RT techniques. However, there are no data on whether these new regimes decrease the risk of cardiovascular disease. In this study the incidence and prevalence of cardiovascular diseases will be estimated 8 and 15 years after both conventional and laser assisted breath controlled RT, and compared with cardiovascular diseases in the general female population. A further aim is to evaluate signs and prevalence of acute cardiotoxicity from RT with the use of cardiac magnetic resonance imaging, coronary fractional flow reserve, ECG and inflammatory and cardiac biomarkers and to investigate whether these signs can predict later cardiovascular disease. The importance of traditional cardiovascular risk factors (age, hypertension, hypercholesterolemia, smoking habits and physical activity, as registered before RT) will also be evaluated.
