Pembrolizumab in Treating Younger Patients With Recurrent, Progressive, or Refractory High-Grade Gliomas, Diffuse Intrinsic Pontine Gliomas, Hypermutated Brain Tumors, Ependymoma or Medulloblastoma
This phase I trial studies the side effects and best dose of pembrolizumab and to see how well it works in treating younger patients with high-grade gliomas (brain tumors that are generally expected to be fast growing and aggressive), diffuse intrinsic pontine gliomas (brain stem tumors), brain tumors with a high number of genetic mutations, ependymoma or medulloblastoma that have come back (recurrent), progressed, or have not responded to previous treatment (refractory). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may induce changes in the body's immune system, and may interfere with the ability of tumor cells to grow and spread.

Testing a Combination of Vaccines for Cancer Prevention in Lynch Syndrome
This phase IIb trial tests whether Tri-Ad5 in combination with N-803 works to prevent colon and other cancers in participants with Lynch syndrome. Each of the three injections in Tri-Ad5 vaccine contain a different substance that is in precancer and cancer cells. Injecting these substances may cause the immune system to develop a defense against cancer that recognizes and destroys any precancer and cancer cells that produce these proteins in the future. N-803 may increase immune responses to other vaccines. Giving Tri-Ad5 in combination with immune enhancing N-803 may lower the chance of developing colon and other cancers in participants with Lynch syndrome.

Energy Balance Interventions in Increasing Physical Activity in Breast Cancer Gene Positive Patients, Lynch Syndrome-Positive Patients, CLL Survivors or High-Risk Family Members
This pilot clinical trial studies different types of energy balance interventions to see how well they work in increasing the physical activity levels of breast cancer gene-positive patients, Lynch syndrome-positive patients, chronic lymphocytic leukemia (CLL) survivors or family members of cancer survivors who are at high risk for cancer. Increasing exercise and eating healthy foods may help reduce the risk of cancer. Studying how well different types of interventions work in motivating cancer survivors or high-risk family members to increase exercise and healthy food choices may help doctors plan the most effective motivational program for cancer prevention.

Evaluation of Capsule Colonoscopy in Patients With Lynch Syndrome
Lynch syndrome is the most common hereditary cancer syndrome and is caused by pathogenic variants in DNA mismatch repair genes, resulting in a markedly increased lifetime risk of colorectal cancer. The estimated lifetime risk of colorectal cancer varies by the affected gene and is approximately 54-74% in men and 30-52% in women with Lynch syndrome. Colorectal cancer in this population is typically diagnosed at a younger age than in the general population. Current national guidelines recommend colonoscopic surveillance every one to two years beginning at 20-25 years of age to reduce colorectal cancer risk. However, individualized modification of surveillance strategies is under active consideration based on factors such as the specific mutated gene, family history of cancer, smoking status, prior malignancies, and age at surveillance initiation. Conventional colonoscopy, the current standard method for colorectal evaluation, may cause substantial discomfort or anxiety, leading some patients to decline participation. Colonoscopy is also resource intensive, and procedural capacity is limited. Previously reported limitations in colonoscopy resources and quality in Sweden highlight the need to evaluate alternative surveillance and screening approaches. Colon capsule endoscopy (CCE) has been available for clinical use since 2006 as a non-invasive alternative to colonoscopy, enabling endoscopic visualization of the entire colon. The system consists of a single-use, swallowable capsule containing miniature cameras that capture images as the capsule progresses through the gastrointestinal tract via natural peristalsis. Images are transmitted wirelessly to a portable data recorder worn by the patient and subsequently reviewed using dedicated software. CCE offers several advantages compared with conventional colonoscopy and CT colonography, including no requirement for sedation, endoscope insertion, gas insufflation, or ionizing radiation. The examination and image acquisition can be performed outside the hospital setting. This patient-centered approach has the potential to improve adherence to repeated examinations and long-term surveillance programs, which is particularly important for individuals with hereditary colorectal cancer syndromes. CCE may also reduce demands on healthcare resources. International guidelines indicate that the mucosal diagnostic performance of CCE is comparable to that of standard colonoscopy and that the method is appropriate for screening purposes. Adequate bowel preparation is required for both colonoscopy and CCE. Unlike conventional colonoscopy, bowel cleansing cannot be optimized during CCE, and the procedure is limited by capsule battery life, typically 10-12 hours. To maintain bowel cleanliness and facilitate capsule transit, patients administer laxative and prokinetic agents at predefined time points during the examination. The primary objective of this study is to evaluate the diagnostic performance and safety of colon capsule endoscopy as a first-line surveillance modality in patients with Lynch syndrome and to assess patient experience and acceptance of CCE compared with conventional colonoscopy.

Cancer Preventive Vaccine Nous-209 for Lynch Syndrome Patients
This phase Ib/II trial evaluates the safety and effect of the Nous-209 vaccine in Lynch syndrome patients. Lynch syndrome is an inherited disorder in which affected individuals have a higher-than-normal chance of developing colorectal cancer and certain other types of cancer, often before the age of 50. In Lynch syndrome, errors in the genetic information inside cells are not properly corrected. When that happens, the cells produce new proteins called neoantigens. Neoantigens are recognized by the body's immune system as foreign, and the body tries to get rid of them. Nous-209 is a vaccine made with man-made copies of some of those neoantigens. This trial aims to see whether the Nous-209 vaccine is safe to give to patients with Lynch syndrome, whether people are able to take the Nous-209 vaccine without becoming too uncomfortable, and how the immune system of patients with Lynch syndrome respond to the Nous-209 vaccine. This trial may help researchers determine whether receiving Nous-209 have an effect on the development of polyps or tumors in the colon.

Menstrual Cup for Early Endometrial Cancer Detection in Lynch Syndrome
Study Goal: This pilot study wants to find out if using a menstrual cup can be a good, non-invasive way to collect samples from the lining of the uterus (called the endometrium) to help screen for endometrial cancer. This is especially important for women who have a higher chance of getting this cancer, such as those with a genetic condition called Lynch syndrome. Main Questions the Study Will Answer: 1. Can a menstrual cup collect enough uterine lining (endometrial tissue) for doctors to examine under a microscope? 2. Are the samples from the menstrual cup as useful for diagnosis as samples taken using the usual method (called an endometrial biopsy or EMB)? 3. Is using a menstrual cup at home easy, effective, and comfortable for participants? 4. Can scientists grow small lab models of the uterus (called organoids) from the menstrual cup samples and from biopsy samples? What Will Happen in the Study: * Participants will use a menstrual cup at home to collect menstrual blood. * They will also have a standard endometrial biopsy done by a healthcare provider. * After both collections, participants will fill out a short survey about how comfortable and easy it was to use the menstrual cup. What the Study Will Measure: * Feasibility: How well participants are able to use the menstrual cup and send in the sample. * Sample Quality: Whether the menstrual cup collects enough good-quality tissue for testing, and how it compares to biopsy samples. * Participant Experience: How women feel about using the menstrual cup, based on the survey. * Lab Testing: Whether researchers can successfully grow endometrial organoids from both types of samples. Why This Study Matters: If this method works, it could offer a gentler, more convenient way for women to get checked for endometrial cancer-especially those who need regular screening. It could also make it easier to collect samples for research and improve early detection of cancer.

Familial Investigations of Childhood Cancer Predisposition
NOTE: This is a research study and is not meant to be a substitute for clinical genetic testing. Families may never receive results from the study or may receive results many years from the time they enroll. If you are interested in clinical testing please consider seeing a local genetic counselor or other genetics professional. If you have already had clinical genetic testing and meet eligibility criteria for this study as shown in the Eligibility Section, you may enroll regardless of the results of your clinical genetic testing. While it is well recognized that hereditary factors contribute to the development of a subset of human cancers, the cause for many cancers remains unknown. The application of next generation sequencing (NGS) technologies has expanded knowledge in the field of hereditary cancer predisposition. Currently, more than 100 cancer predisposing genes have been identified, and it is now estimated that approximately 10% of all cancer patients have an underlying genetic predisposition. The purpose of this protocol is to identify novel cancer predisposing genes and/or genetic variants. For this study, the investigators will establish a Data Registry linked to a Repository of biological samples. Health information, blood samples and occasionally leftover tumor samples will be collected from individuals with familial cancer. The investigators will use NGS approaches to find changes in genes that may be important in the development of familial cancer. The information gained from this study may provide new and better ways to diagnose and care for people with hereditary cancer. PRIMARY OBJECTIVE: * Establish a registry of families with clustering of cancer in which clinical data are linked to a repository of cryopreserved blood cells, germline DNA, and tumor tissues from the proband and other family members. SECONDARY OBJECTIVE: * Identify novel cancer predisposing genes and/or genetic variants in families with clustering of cancer for which the underlying genetic basis is unknown.

Overcoming Barriers to Uptake of Cascade Screening
Lynch syndrome is a genetic condition that increases cancer risk. The public health impact of genetic testing for disease prevention hinges on cascade screening, which is the systematic identification and testing of blood relatives after a family member has been diagnosed with a genetic condition. Despite its importance in disease prevention, only half of first-degree relatives of individuals with Lynch syndrome undergo cascade screening. To address this gap, the study will pilot test an online version of Let's Talk, a novel intervention designed to support and promote cascade screening. This intervention tool is designed to support and encourage more family members to get screened. The purpose of this study aim is to assess the feasibility of the online Let's Talk tool in clinical use by examining implementation and effectiveness outcomes related to the use of the planning tool across three clinics at a large academic-affiliated medical center with patients (n=15) seen by one of five genetic counselors (n=5).

Strategy for Management of Patients With Hereditary Cancer Syndromes (HCS) in a Rural Environment
This study aims to improve cancer prevention and surveillance adherence in patients with Hereditary Cancer Syndromes (HCS), particularly those living in rural areas. The study will evaluate whether enrolling HCS patients in a longitudinal clinical program with individualized care plans and regular follow-up improves adherence to guideline-recommended cancer screening and risk-reduction strategies. Secondary aims include assessing the program's impact on patient distress and perceived care coordination. The study will enroll 200 adults with known pathogenic germline mutations who were previously seen at the UVM Medical Center genetics clinic. Participants will complete surveys at baseline, 12, and 24 months to assess adherence, distress, and care coordination. Findings from this study will inform future efforts to reduce gaps in hereditary cancer care delivery, especially for rural populations.

Combination Chemotherapy With or Without Atezolizumab in Treating Patients With Stage III Colon Cancer and Deficient DNA Mismatch Repair
This phase III trial studies combination chemotherapy and atezolizumab to see how well it works compared with combination chemotherapy alone in treating patients with stage III colon cancer and deficient deoxyribonucleic acid (DNA) mismatch repair. Drugs used in combination chemotherapy, such as oxaliplatin, leucovorin calcium, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving combination chemotherapy with atezolizumab may work better than combination chemotherapy alone in treating patients with colon cancer.

Study Aiming to Test Whether Non-invasive Liquid Biopsies Can Safely Reduce Invasive Surveillance Methods in Lynch Syndrome
Lynch syndrome is an inherited genetic predisposition that increases the risk of developing several types of cancer, particularly colon and rectal cancers (colorectal cancer), as well as cancer of the uterine lining (endometrial cancer). It affects around 1 in 400 people in Europe. Today, surveillance mainly relies on examinations such as colonoscopy (an examination of the colon using a camera) or gynaecological evaluations, sometimes accompanied by biopsies (the removal of a small tissue sample for microscopic analysis). Although effective, these procedures are invasive and demanding; they can affect quality of life and discourage some individuals from adhering to their recommended surveillance programme. The European project PREDI-LYNCH is exploring an additional pathway that is simpler and better tolerated. This project relies on "liquid biopsies", meaning tests performed on easily collected samples such as blood, urine, stool, and vaginal swabs for women with a uterus. The PREDI-LYNCH study aims to determine whether these non-invasive tests could enable personalised surveillance and potentially increase the interval between more burdensome procedures, while maintaining a high level of medical safety.
