Randomized Double-Blind Phase II Trial of Baby Exemestane Versus Baby Tamoxifen in Post-Menopausal Women at High Risk for Breast Cancer
The goal of this research study is to evaluate the efficacy and safety of low-dose exemestane versus low-dose tamoxifen in post-menopausal women at high risk for breast cancer. The names of the study drugs involved in this study are: * Exemestane (a type of steroidal aromatase inhibitor) * Tamoxifen (a type of selective estrogen receptor modulator)

Olaparib In Metastatic Breast Cancer
This research study is for patients with metastatic breast cancer. * Metastatic means that the cancer has spread beyond the breast. In addition, through genetic testing of the blood or tumor, an altered gene has been found that suggests the tumor may not be able to repair its genetic material (DNA) when it becomes damaged. * This aspect of the cancer may cause it to be more sensitive - that is, more effectively killed by certain types of drugs such as the study agent being evaluated in this trial, Olaparib. * Olaparib is a type of drug known as a PARP inhibitor. Some types of breast cancer and ovarian cancer share some basic features that make them sensitive to similar treatments. Information from those other research studies suggests that this drug may help to treat metastatic breast cancer. * This study will evaluate whether olaparib is effective in breast cancer patients whose tumor has a mutation in one of the other genes that function with BRCA1 and BRCA2 to repair damaged DNA .This mutation may have been inherited from a parent, or may have developed only in the tumor. * This study will also evaluate whether olaparib is effective in breast cancer patients whose tumor has a mutation in BRCA1 or BRCA2 that was acquired by the tumor, but not inherited.

The GENPET Study - An Imaging Study of FCH-PET-CT in Men With Prostate Cancer and a DNA Repair Gene Mutation.
The aim of the study is to determine if PET-CT imaging (using contrast recommended in clinical guidelines) is superior to combined bone scan and MRI/CT of the abdomen \& pelvis in detecting the increased incidence of metastasis (nodal/distant outside the pelvis) in men with prostatic carcinoma with mutations in any of the following germline DNA repair genes BRCA1, BRCA2, MSH2, MSH6, MLH1, PMS2, CHEK2, PALB2, ATM.

An Intervention to Increase Genetic Testing in Families Who May Share a Gene Mutation Related to Cancer Risk and An Intervention to Help Patients and Their Primary Care Providers Stay Up-to-date About Uncertain Genetic Test Results
The purpose of this study is to examine the impact of new cancer genetic counseling models that aim to increase patient engagement with the genetics team. To do this, the study consists of two trials to evaluate two related interventions. The first trial is the EfFORT Trial, which evaluates a cascade genetic testing intervention. Cascade testing is the process of offering genetic testing to people who are at risk of having inherited a possibly harmful gene change that has been found in their family. The study will look at how often genetic testing occurs when healthcare providers have permission to reach out to family members to recommend genetic testing and to help those who are interested get tested. The study will look at whether this cascade testing intervention is practical and effective. The study would like to see how this approach of healthcare providers reaching out directly to family members compares with the usual approach of patients telling their family members about the recommendation to get genetic testing. The second trial is the STRIVE Trial, which evaluates an intervention designed to help patients who receive an uncertain result from genetic testing (also called a "variant of uncertain significance") stay connected with their genetics care team, and to help patients and their primary care providers stay up-to-date about the meaning of uncertain genetic test results. The study will look at whether an intervention that consists of a study online portal for patients with uncertain genetic test results and their primary care providers will help them to stay up-to-date on the meaning of uncertain genetic test results. The study would like to see how this intervention compares to the usual approach of encouraging patients to re-contact their genetics care team on their own about a year after getting genetic testing."

Low Dose TamOxifen and LifestylE Changes for bReast cANcer prevenTion
Circulating levels of Sex Hormone Binding Globulin (SHBG) are significantly associated with a decreased risk of breast cancer. The main aim of this clinical trial is to verify whether Low Dose Tamoxifen (LDT) increases circulating levels of SHBG more than lifestyle intervention (LI) with or without intermittent caloric restriction (ICR) after 6 months in women at increased risk of breast cancer (i.e., healthy participants carriers of a germline pathogenic/likely pathogenetic variant in at least one of the following genes: BRCA1, BRCA2, PALB2, ATM, CHEK2, CDH1, RAD51C or RAD51D, or with \> 5% breast cancer risk at 10 years, using the Tyrer Cuzick or the Breast Cancer Surveillance Consortium Risk models or with a recently resected intraepithelial neoplasia of the breast (IEN). The secondary aims are: * to verify whether ICR significantly modulates primary and secondary endpoints such as Homeostasis Model Assessment (HOMA) index, immune and inflammatory markers, lipid profile, Adiponectin/Leptin (A/L) ratio, quality of life (QoL), Body mass index (BMI), fat body composition, safety and toxicity; * to verify whether LDT significantly modulates secondary endpoints, such as HOMA-index, immune and inflammatory markers, lipid profile, A/L ratio, QoL, BMI, fat body composition, safety and toxicity; * to investigate differences in microbiome composition by arms and the effect of changes in microbiome on QoL taking into account circulating biomarkers, cytokines, immune modulators, and inflammatory proteins in serum; * to investigate MD (Mammographic Breast Density) changes by LDT vs. LI, with or without ICR. This aim will be performed in a subgroup of participants (not all the participants will undergo mammography due to younger age).

Niraparib Before Surgery in Treating Patients With High Risk Localized Prostate Cancer and DNA Damage Response Defects
This phase II trial studies how well niraparib, when given before surgery, works in treating patients with high risk prostate cancer that has not spread to other parts of the body (localized) and alterations in deoxyribonucleic acid (DNA) repair pathways. Niraparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Video Capsule Examination in Patients With Lynch Syndrome
Surveillance for colorectal cancer (CRC) in patients predisposed to develop CRC during their lifetime has been impacted by access to colonoscopy suites and endoscopy specialists in the past couple of years. An alternative method, namely the colon capsule, has been proposed, however this investigation is time consuming for the clinician and the images require up to one hour (30-60 minutes) reading to issue a result. The investigators propose to obtain images from paired colonoscopies and colon capsules with the purpose of developing an AI algorithm which could aid the clinicians in reading the colon and expand access to this investigation. The main aim of the study is to determine whether it is possible to obtain usable paired images from patients with Lynch and other cancer predisposition syndromes. This will depend on the willingness of the patients to take part in the study and the technical ability of obtaining data from paired images of colonoscopies and colon capsule. At recruitment, participants will undergo a colon capsule investigation, followed by a routine colonoscopy as per their normal standard of care. Paired endoscopic images from colonoscopies and colon capsules will be collected and anonymised data will be accessed by the bioinformatician for analysis. If the study will be successful in reaching the primary endpoint, further trials will be opened, allowing for a larger population to be included and to obtain more robust data, which eventually can lead to validated AI algorithms and application of computer-aided video-capsules examination as a screening tool in at-risk population.
