Administering Peripheral Blood Lymphocytes Transduced With a Murine T-Cell Receptor Recognizing the G12V Variant of Mutated RAS in HLA-A*11:01 Patients

Background: A new cancer therapy involves taking white blood cells from a person, growing them in the lab, genetically modifying them, then giving them back to the person. This therapy is called gene transfer using anti-KRAS G12V mTCR cells. Objective: To see if anti-KRAS G12 V mTCR cells are safe and can shrink tumors. Eligibility: Adults at least 18 years old with cancer that has the KRAS G12V molecule on the surface of tumors. Design: In another protocol, participants will: Be screened Have cells harvested and grown Have leukapheresis In this protocol, participants will have the procedures below. Participants will be admitted to the hospital. Over 5 days, participants will get 2 chemotherapy medicines as an infusion via catheter in the upper chest. A few days later, participants will get the anti-KRAS G12V mTCR cells via catheter. For up to 3 days, participants will get a drug to make the cells active. A day after getting the cells, participants will get a drug to increase their white blood cell count. This will be a shot or injection under the skin. Participants will recover in the hospital for 1-2 weeks. They will have lab and blood tests. Participants will take an antibiotic for at least 6 months. Participants will have visits every few months for 2 years, and then as determined by their doctor. Visits will be 1-2 days. They will include lab tests, imaging studies, and physical exam. Some visits may include leukapheresis or blood drawn. Participants will have blood collected over several years.

Phase I/II Study of Celebrex and EPO906 in Patients With Metastatic Colorectal Cancer

This study is for people with advanced colorectal cancer. This study uses the drugs Celebrex and EPO906. EPO906 is an experimental drug that has not been approved by the FDA. EPO906 is a drug that has been shown in the laboratory to cause cancer cells to die and prevents them from growing and reproducing. Celebrex is a drug that is approved by the FDA for the treatment of arthritis and prevention of colon polyps. Colon polyps are small growths in the colon. If not surgically removed, some colon polyps can become cancerous. Some studies have shown that Celebrex may reduce the side effects of chemotherapy. Other studies have shown that it may increase the effectiveness of some chemotherapy. Celebrex is not approved by the FDA for reducing the side effects of chemotherapy or improving the effectiveness of chemotherapy. The combination of EPO906 and Celebrex in this study is experimental. The main goal of this study is to see if adding the drug Celebrex to the drug EPO906 will decrease the amount of diarrhea seen in patients that receive EPO906. The goal of the first phase of this study is to find the highest dose of EPO906 that can be given safely with Celebrex. The dose of Celebrex will remain the same for the whole study. Higher doses of EPO906 will be given to each group of patients. The increase of EPO906 will stop once more than one patient has serious side effects. The highest dose of EPO906 that can be given with Celebrex (without serious side effects) will be called the pilot dose. The goal of the second phase of this study is to find out how tumors respond to these doses of the drugs. Another purpose of this study is to see how the body processes the EPO906 and Celebrex. This study will also look at the side effects of these drugs. In this study, we will measure how long subjects live, how often tumors shrink after receiving the study drugs, and how long it takes for tumors to increase in size after receiving the study drugs. This study will also measure the levels of genes, which are the cell's blueprint, in participant's tumors. Several genes can affect how people's bodies react to the cancer drugs. Genes will also be measured in participant's blood. We want to see if these predict response to the study drugs.

EQUITY GI: A Prospective Study to Enhance Quality, Inclusivity, and Trial Participation in Black Patients With Gastrointestinal Cancer.

This research study is being conducted to improve the quality of care of participants who have a diagnosis of gastrointestinal cancer (anal, colon, rectal, esophageal, stomach, small bowel, appendix, pancreas, gall bladder, liver, neuroendocrine tumor of gastrointestinal origin). This study has 3 components as follows- 1. Ensuring appropriate biomarker testing and evidence-based care: Biomarkers are molecules in the tumor or blood that indicate normal or abnormal processes in participant's body and may indicate an underlying condition or disease. Various molecules, such as DNA (genes), proteins, or hormones, can serve as biomarkers since they all indicate something about participant's health. Biomarker testing can also help choose participant's treatment. Additionally, a tumor board will be conducted periodically to provide treatment recommendations to participant's treating physician. Participants will receive standard-of-care treatment if participant enroll in this study. Participant will not receive any experimental treatment. 2. Assistance with clinical trial enrollment. The study team will help participants enroll in a clinical trial appropriate for participant's condition. However, enrolling in a clinical trial is totally up to the participant. 3. Health literacy: The study team will provide information relevant to participant's diagnosis to enrich participant's understanding of participant's condition and treatment. Investigator will provide questionnaires to assess participant's understanding before and after participant's have been provided with educational/informational material appropriate for participant's diagnosis.

Risk Communication Within Mexican-American Families

This study will examine what methods work best for encouraging Mexican-American family members to talk about their risk for diabetes, heart disease, breast cancer and colon cancer. Within the Mexican-American community, the family culture provides an important setting in which individuals interpret and share their health information and formulate strategies to engage in health-promoting behaviors. The information from the study will be used to design risk communication approaches for Mexican-American households. Members of households with at least three adults 18 to 70 years of age who are part of the existing Mexican-American households recruited by the University of Texas M.D. Anderson Cancer Center may be eligible for this study. Participants are interviewed about their medical history, family history of disease, health behaviors, beliefs about disease and disease risk, experiences living in the United States, and relationships with family members and close friends. They are then provided information about their family risk for diabetes, heart disease, breast cancer and colon cancer, based on the information they provided in the interview. Two additional interviews are conducted over the telephone that include questions about how the participants communicate with family members about their risk and health behaviors.

FOLFOX or CAPOX Perioperative Chemotherapy Versus Postoperative Chemotherapy for Locally Advanced Colon Cancer (OPTICAL)

BACKGROUND: In patients with high risk stage II and stage III colon cancer (CC), curative surgery followed by adjuvant chemotherapy with FOLFOX or CAPOX regimens has become a standard treatment. However, 20 to 30 % of these patients will develop distant metastasis, which ultimately result in death. Perioperative chemotherapy is a promising strategy with potential benefits that could be more effective at eradicating micrometastases. Moreover, shrinking tumor before surgery not only facilitate removal of all the tumor by the surgeon but also reduce tumor cell spreading during the procedure. With recent advances in radiology, preoperative computed tomography is a robust method for measuring the depth of tumor invasion and identifying the CC patients with poor prognosis, who may benefit from perioperative chemotherapy. The investigators conducted the present randomized study to explore whether perioperative chemotherapy with FOLFOX or CAPOX regimens compared with postoperative chemotherapy could improve disease-free survival in patients with radiologically staged, locally advanced, but resectable colon cancer. OBJECTIVE: The primary objective of this study is to evaluate the efficacy of perioperative chemotherapy with FOLFOX or CAPOX regimens compared to postoperative chemotherapy in patients with locally advanced colon cancer. Secondary objectives are efficacy in terms of R0 resection rate, overall survival (OS), relapse-free survival (RFS), down-staging of primary tumors, and tolerability of perioperative therapy and postoperative complications.

Ovarian-Sparing Adaptive Radiotherapy in Young Adult Women

Female patients with early onset (\<50 years old) pelvic malignancies such as uterine and rectal cancers are rising in incidence, which often requires pelvic radiation; many of these patients are premenopausal and at a high risk of premature ovarian failure from radiotherapy. Premature ovarian failure carries significant cardiac, musculoskeletal, sexual, and psychosocial morbidity. Ovarian transposition carries variable success rates, is not readily accessible to the general population, and can still be at risk of clinically significant radiotherapy doses. There is an unmet need for innovative techniques to protect ovarian function.

Brodalumab in the Treatment of Immune-Related Adverse Events

The purpose of this study is to test the safety and effectiveness of using brodalumab in patients who develop side effects from cancer immune therapy. Immune-related side effects are due to activation of the immune system in patients who previously received immunotherapy and the goal of this study is to help better control these side effects. Brodalumab is often used to treat patients with autoimmune diseases (diseases where the immune system is activated against normal organs) and safe doses and treatment schedules have been determined in these patients. Immune-related side effects appear to closely mirror these autoimmune conditions. Brodalumab has not been approved by the United States Food and Drug Administration (FDA) for use in immunotherapy side effects but it has been approved for treatment of autoimmune conditions.

Genomic Services Research Program

Background: Genes are the instructions a person s body uses to function. Genome sequencing reads through all of a person s genes. Everyone has many gene variants, and most do not cause disease. Some gene variants called secondary findings may be important for a person s health even if they are not related to the reason why a person had genome sequencing done. Researchers want to learn more about what it means to have a secondary finding. Objectives: To learn about how gene variants may affect a person s health. To learn about how people understand their genetic test results. Eligibility: People with secondary findings from genetic testing done as part of a research study, clinical care, or other methods. Design: Participants may be asked to do an online survey and phone interview to ask what they think about their results, their healthcare, and if they talk with their family about the result. Eligible participants may be offered a visit to the NIH Clinical Center where they will be evaluated for health problems related to the secondary finding. DNA samples that were already collected may be studied. Participants may be asked to send in a second DNA sample (blood or saliva). These will be used to verify any findings. Participants who have a secondary finding can get genetic counseling.

Mainstreaming Genetics: Evaluation of a Digital Application to Scale and Spread Oncologist-initiated Genetic Testing

Genetic testing can alter therapy and surgical management for cancer patients and is therefore indicated as a first-line test for many newly diagnosed patients, including breast, ovarian, pancreatic, prostate and colon/GI patients. To reduce pressure on already constrained genetics clinics across Canada, some cancer centres are 'mainstreaming' genetic testing - whereby genetic testing is initiated and mediated by oncologists without traditional pre-test genetic counseling (GC) often using some form of paper-based patient pamphlets or videos. There is no standard, evidence-based approach to mainstreaming, leading to significant practice variation, a lack of coordinated care and ultimately, negative psychological impacts on patients. Digital solutions can address these gaps by providing a standardized, coordinated and patient-centered approach to deliver cancer genetic education. However, digital solutions for providing cancer genetics services are uncommon and clinical-effectiveness and service delivery outcomes have not been well-assessed. This study will test a digital mainstreaming platform called the Genetics Adviser for Mainstream care to assess its effectiveness in improving psychological outcomes and patient-centred care for mainstream cancer patients compared to standard of care.
