Obtaining Solid Tumor Tissue From People Having Biopsy or Surgery for Certain Types of Cancer

Background: - Recent advances in cancer research have led to new therapies to treat the disease. It is important to continue these advances and discover new ones. To do that, researchers need tissue samples from solid tumors. This study will collect such samples from people already scheduled to have a procedure at the National Institutes of Health Clinical Center (NIHCC). Objectives: - To collect tissue samples for use in studying new ways to treat tumors. Eligibility: Adults 18 years and older, with a precancerous or cancerous solid tumor who are scheduled to have surgery or a biopsy at the NIHCC. Children under the age of 18 but who are older than 2 years of age are eligible to be enrolled on the research sample collection portion of this study if they will have a biopsy or surgery as part of their medical care. Design: Before their procedure, participants will have a small blood sample taken. Some participants will undergo leukapheresis. In this procedure, blood is removed through a tube in one arm and circulated through a machine that removes white blood cells. The blood, minus the white blood cells, is returned through a tube in the other arm. The procedure takes 3-4 hours. For all participants, during the surgery or biopsy, pieces of the tumor and pieces of normal tissue near it will be removed for this study. The rest of the tumor or precancerous growth will be sent to a lab for analysis. Participants will return to the clinic about 6 weeks after the operation for a routine checkup. Some may have to return for additional follow-up.

Phase I/II Study of the Anti-Programmed Death Ligand-1 Antibody MEDI4736 in Combination With Olaparib and/or Cediranib for Advanced Solid Tumors and Advanced or Recurrent Ovarian, Triple Negative Breast, Lung, Prostate and Colorectal Cancers

Background: - MEDI4736 is a drug that may help people s immune systems respond to and kill cancer cells. Olaparib is a drug that may inhibit repairing DNA damage of cancer cells. Cediranib is a drug that may stop the blood vessel growth of cancer cells. This study has two components. In the phase 1 component of the study, researchers want to investigate how well participants tolerate the combination of these drugs in treating advanced solid tumors, and in the phase 2 part of this study, researchers want to study if the combination treatments are effective in ovarian cancer. Objectives: - Phase 2 part of the study: To determine how effective this combination is in treating ovarian cancer. Eligibility: - Phase 2 part of the study: Adults age 18 or older with advanced or recurrent ovarian cancer that has no standard treatment. Design: Participants will be screened with medical history, physical exam, and blood and urine tests. They will have CT or MRI scans. For these, they will lie in a machine that takes pictures of their bodies. Phase 2 part of the study requests the participants to have tumor samples removed. Participants will get MEDI4636 through an IV. A small plastic tube will be inserted into a vein. The drug will be given every 4 weeks until disease progression. Participants will take olaparib or cediranib by mouth every day. Every 28 days will be 1 cycle. For cycle 1, participants will have 2 study visits. All other cycles, they will have 1 visit. At these visits, they will repeat the screening procedures. Patients will keep a drug and diarrhea diary. Patients on cediranib will monitor their blood pressure and keep a blood pressure diary. Participants who can become pregnant, or have a partner who can become pregnant, must practice an effective form of birth control. After 12 cycles, participants will have 1-3 months of follow-up.

Feasibility Study of a 4 Stage Bowel Obstruction Cancer Diet

Bowel obstruction is a common complication in patients with ovarian, peritoneal and bowel cancer due to a mass or spread of disease, causing narrowing to the gut, as these cancers can grow on the bowel surface. Certain foods may lead to symptoms such as pain, bloating, feeling full, feeling sick, vomiting and difficulty passing a bowel motion. There is limited evidence to establish the best diet to follow when someone is diagnosed with the risk of bowel obstruction and is experiencing symptoms after eating and drinking. The Dietitians at the Royal Surrey have developed a 4 stage bowel obstruction diet which they have been using with patients for 3 years. The 4 stages are clear fluids, all thin liquids, low fibre soft smooth diet, low fibre soft sloppy diet. Depending on the severity of symptoms and the risk of a blockage, patients are asked to follow a certain stage of the diet. They are advised to move up and down the stages as symptoms improve or get worse. This feasibility study aims to investigate if the diet can be used and is effective in clinical practice. The objectives are to see if this diet is easy to follow, can reduce symptoms of bowel obstruction, can improve quality of life, and reduce admissions to hospital because of bowel blockages. Patients at risk of bowel obstruction from colorectal or ovarian cancer are eligible to participate. They will remain in the study for a period of 4 weeks, during which time they will be asked to complete a diet diary and 3 questionnaires.
