Increasing Screening for Cancer Using EHR-Nudges Replication
In this study, personalized nudges to clinicians and patients will be evaluated to help increase breast cancer screening rates in accordance with USPSTF guidelines among women with a primary care visit. In partnership with Penn Medicine (Penn) and Case Western Reserve University-University Hospitals (UH), two complementary, concurrent 6-month, cluster randomized, pragmatic trials were conducted from December 2023 to October 2024. This trial will now replicate those interventions at Lancaster General Health (LGH), incorporating learnings from the primary trials while also adapting to align with existing health system protocols and policies. The patient nudge interventions include pre- and post-visit text message reminders to encourage the patient to schedule their mammogram, and the clinician nudge intervention includes a Smart Data Element message in the electronic health record (EHR) reminding the care team that the patient is overdue and that patients are more likely to complete their screening if recommended and ordered by their clinician.

Study to Investigate Efficacy of a Novel Probiotic on the Bacteriome and Mycobiome of Breast Cancer
The purpose of this study is to examine the effect of probiotics on the breast tumor microbiome and gut microbiome in breast cancer. Microorganisms that make up the microbiome (such as viruses, bacteria, and fungi) may have an important role in breast cancer development. Understanding the association of microorganisms with breast cancer may enable new ways to prevent, diagnose, and treat breast cancer. The probiotic, BIOHM, which is owned and distributed by BIOHM Health LLC, will be used in this study. BIOHM is a food supplement that is believed to balance bacteria and fungi in the body and has received the designation as Generally Recognized as Safe (GRAS) by the Food and Drug Administration (FDA). This study is being done to determine the effectiveness of BIOHM in breast cancer.

Artificial Intelligence and Machine Learning to Guide CDK4/6 Inhibitor Rechallenge in Breast Cancer.
The goal of this clinical trial is to learn if an artificial intelligence model will be able to select patients with advanced breast cancer who may respond to a second cyclin-dependent kinase 4/6 (CDK4/6) inhibitor after they have progressed on the first CDK4/6 inhibitor. Patients for this study need to have hormone receptor positive (HR+) human epidermal growth factor receptor 2 negative (HER2-) advanced breast cancer. The main questions the study aims to answer are: If the artificial intelligence model says that a patient's tumor should respond to the second CDK4/6 inhibitor, and that patient receives the second CDK4/6 inhibitor together with fulvestrant (an endocrine therapy also called Faslodex), will it take longer for the tumor to get worse than if the patient receives another type of therapy? Will the tumor respond better? Will the therapy be safe? Researchers will compare the combination of a second CDK4/6 inhibitor plus fulvestrant to the therapy chosen by the physician. Participants will: Take the assigned therapy based on the way the therapy is usually prescribed. Visit the clinic once every month for checkups, tests, and questionnaires. Keep a diary of the pills they take at home.

Natural History Study of Early Life Exposures in Agriculture (ELEA)
Study Description: ELEA is an observational cohort study that will collect exposure information and biospecimens from the adult children of the Agricultural Health Study (AHS) cohort (https://aghealth.nih.gov/about; Protocol OH93NCN013). The primary hypothesis is that early life exposures, particularly those found in the agricultural environment, are associated with cancer and other adverse health outcomes in childhood and early adulthood. Eligible individuals will be invited to complete an online questionnaire. After enrollment, study participants may be asked to donate biological and environmental samples. Participants will be followed for cancer and other disease endpoints. Data will be collected from North Carolina and Iowa health registries, disease specific databases, the National Death Index (NDI), North Carolina and Iowa state health registries, publicly available environmental datasets, discarded sample repository, and collection of available samples. Investigators will access data and biospecimens from the AHS protocol OH93NCN01 and link it to the ELEA population. In an earlier ELEA protocol (16CN095) the NCI SS IRB approved the protocol to perform linkages. That protocol was closed after the transition to the NIH IRB (per a NHSR determination), but the linkage work continued under the ELEA protocols that remained open with Westat and Iowa. Objectives: Primary: To investigate the effect of specific pesticides and other agricultural exposures and risk of cancer in children and adults. Secondary: To investigate the effect of non-agricultural exposures and the risk of cancer and other diseases in children and adults. Exploratory: Exploratory objectives include, but are not limited to, the examination of genetic and various molecular biomarkers in relation to childhood agricultural exposures. Endpoints: Primary: Incidence of Cancer Secondary: Incidence of diseases other than cancer, survival, and various molecular biomarkers. ...

Patient-Derived Organoids to Functionally Characterize Chemotherapy Resistance in Breast Cancer
This prospective observational study aims to functionally characterize chemotherapy resistance in patients with locally advanced breast cancer undergoing neoadjuvant chemotherapy. Despite standard molecular classification, significant heterogeneity in treatment response exists, and the biological mechanisms underlying chemoresistance remain incompletely understood. In this study, patient-derived organoid (PDO) models will be established from tumor tissues obtained during routine clinical care. These three-dimensional models preserve the biological characteristics of individual tumors and enable ex vivo functional assessment of drug response. Chemotherapy sensitivity and resistance will be evaluated using quantitative parameters including IC50 values, cell viability, and apoptotic response. Functional data obtained from PDO models will be correlated with clinical and pathological treatment outcomes, particularly pathological complete response (pCR), to assess the predictive value of PDO-based assays. In addition, apoptotic biomarkers such as Caspase-3/7 will be measured in serum samples collected during routine clinical evaluation and analyzed in relation to treatment response. Furthermore, selected FDA- and EMA-approved small molecules will be tested in PDO models to evaluate their potential to reverse chemotherapy resistance, supporting drug repurposing strategies. This study aims to establish a functional, patient-specific platform for assessing chemoresistance and to contribute to the development of personalized therapeutic approaches in breast cancer.

Administration of Autologous T-Cells Genetically Engineered to Express T-Cell Receptors Reactive Against Neoantigens in People With Metastatic Cancer
Background: A person s tumor is studied for mutations. When cells are found that can attack the mutation in a person s tumor, the genes from those cells are studied to find the parts that make the attack possible. White blood cells are then taken from the person s body, and the gene transfer occurs in a laboratory. A type of virus is used to transfer the genes that make those white blood cells able to attack the mutation in the tumor. The gene transfer therapy is the return of those white blood cells back to the person. Objective: To see if gene transfer therapy of white blood cells can shrink tumors. Eligibility: People with certain metastatic cancer for which standard treatments have not worked. Design: Participants may complete screening under another protocol. Screening includes: * Getting tumor cells from a previous procedure * Medical history * Physical exam * Scans * Blood, urine, heart, and lung tests The study has 8 stages: 1. Screening tests repeated over 1-2 weeks. Participants will have leukapheresis: Blood is removed by a needle in one arm. A machine removes white blood cells. The rest of the blood is returned by a needle in the other arm. 2. Care at home over approximately 12 weeks. 3. Stopping therapy for 4-6 weeks while their cells are changed in a lab. 4. Hospital stay approximately 3-4 weeks for treatment. An IV catheter will be placed in the chest to administer drugs. 5. Patients on Arm 2 of the study will receive the first dose of pembrolizumab while in the hospital. Three additional doses will be given after the cell infusion 3 weeks apart. 6. Receiving changed cells by catheter. Then getting a drug over 1-5 days to help the cells live longer. 7. Recover in the hospital for 1-2 weeks. Participants will get drugs and have blood and urine tests. 8. Participants will take an antibiotic and maybe an antiviral for at least 6 months after treatment. They will have repeat screening tests at visits every few months for the first year, every 6 months for the second year, then as determined. ...

Breast Margin Study: Routine Cavity Shave Margins Vs. Selective Margins Using Savi Scout®
This is a prospective study comparing partial mastectomy performed with routine cavity shave margins and Savi Scout® localization to partial mastectomy performed with selective margins and Savi Scout® localization. The primary objective is to determine the difference in positive margin rate between the two methods. The secondary objectives are to determine the differences in the rate of re-excision, volume of tissue extracted and Breast-Q® score between the two methods. It is hypothesized that the Savi Scout® will allow for decreased volume of tissue excised when compared to routine cavity shave margins without any difference in positive margin rate or rate of re-excision.
