Background: Mesothelioma is an aggressive cancer that grows in the linings of the body; this can include the membranes that line the heart, lungs, and internal organs. Mesothelin (MSLN) is a protein that appears in high numbers in many tumors, including mesothelioma. Researchers are developing a new treatment that collects a person s own immune cells (T cells); the T cells are genetically modified to target and kill tumor cells with high levels of MSLN. Objective: To test a new treatment (TNhYP218 CAR T cells) in people with solid tumors including mesothelioma. Eligibility: People aged 18 and older with solid tumors including mesothelioma that returned or spread after standard treatment. Design: Participants will be screened. A small piece of tissue will be cut from a tumor (biopsy). The sample will be tested to see if it has enough MSLN. Participants will undergo leukapheresis: Blood will be taken from their body through a vein. The blood will pass through a machine that separates out the T cells. The remaining blood will be returned to the body through a different vein. Participant s T cells will be modified in a lab to produce TNhYP218 CAR T cells. Participants will enter the hospital. For 7 days, they will receive drugs to prepare their bodies for the study treatment. TNhYP218 CAR T cells will be administered into a vein. Participants will remain in the hospital for at least 7 more days. After discharge, participants will have follow-up visits for 5 years. These visits may include imaging scans, blood and heart tests, and a new biopsy. Long-term follow-up will continue another 10 years....

This study will evaluate and gather information in patients with genetic causes of too much androgen (male-like hormone) in order to better understand the effects of too much androgen and describe problems associated with it. Too much androgen in childhood, if untreated, results in rapid growth and early puberty with early cessation of growth and short stature in adulthood. Too much androgen in adulthood may result in infertility, and women may have excess facial hair, acne and a more male-like appearance. Excess androgen may also affect mood and behavior and possibly the secretion of other hormones, such as insulin. Two genetic diseases that result in early childhood androgen excess are congenital adrenal hyperplasia (CAH) and familial male-limited precocious puberty (FMPP). Patients with known or suspected CAH due to 21-hydroxylase deficiency, 11- hydroxylase deficiency, or 3-beta-hydroxysteroid dehydrogenase deficiency and males with known or suspected FMPP may be eligible for this study. Patients with both classic and non-classic CAH are eligible, and patients with androgen excess of unknown cause may be eligible. Participants undergo the following procedures: - Medical history and physical examination. - Fasting blood tests for analysis of hormones, blood chemistries including blood sugar and cardiovascular risk factors such as lipids. - Oral glucose tolerance test for patients with elevated insulin levels. For this test, a catheter (plastic tube) is placed in a vein in the patient's arm. The patient drinks a sugar-containing fluid and blood samples are collected through the catheter at intervals starting with drinking the solution, and then 30, 60 and 120 minutes after drinking the solution. - 24-hour urine collection to measure hormone levels in the urine. - DNA testing for patients with 21-hydroxylase deficiency to help identify the type of genetic mutation responsible for the disease. - X-ray of the left hand to measure bone age in growing children. The x-ray is used to determine how far into puberty the child is and how much growth potential is left in the bones. - A pelvic ultrasound in females and testicular ultrasound in males to evaluate the size and development of the gonads (ovaries in females and testes in males). - Cognitive and psychological tests, including an IQ test and evaluation of memory, achievement and behavior. - Other tests and evaluations based on medical need. The schedule for these procedures varies. In a part of the study involving only patients with CAH, growing children are evaluated twice (once in childhood and once after reaching adult height), and adults are evaluated once. In another part of the study involving patients with CAH and FMPP, growing children are seen twice a year, and adults and children who have reached adult height may be seen annually. Additional visits may be scheduled if medically indicated. In this part of the study, females are asked to keep a record of their periods after their first menstrual cycle. ...

Background: Scientists have long used simple measures (such as height and weight) to estimate how much a person s body uses food (calories) as energy, as commonly called the metabolic rate. But metabolism varies among people with similar body sizes. Scientists now believe the old formulas for estimating metabolic rates may not work well for all people. Researchers want to find more accurate ways to measure a person s metabolism. Objective: This natural history study will examine the relationships between metabolism, body composition, and body surface area in a wide range of people. Eligibility: Healthy children and adults aged 2 years or older. Also, people aged 2 years or older with conditions that may alter metabolism. These may include diabetes, obesity, renal disease, or cancer. Design: Participants will spend 2 days and 1 night in the hospital. They will provide a medical history and answer questions about their activity levels, the foods they eat, and their lifestyle. They will also eat a special diet. Participants will undergo many tests: They will lie in a bed with a clear hood covering their head for 30 to 45 minutes to measure the gases in their breath. They will lie on a padded table for about 15 minutes while their body is scanned. They will stand on a platform while a 3D scanner measures their body. They will have a test to measure how fast an electric signal moves through their body. They will grip an instrument to measure the strength of their hands. They will drink salty water and provide blood and urine samples. Participants may be invited to return for these 2-day visits up to 8 times per year. Return visits must be at least 2 weeks apart.

Background: The NCI Surgery Branch has developed an experimental therapy that involves taking white blood cells from patients' tumors, growing them in the laboratory in large numbers, and then giving the cells back to the patient. These cells are called Tumor Infiltrating Lymphocytes, or TIL and we have given this type of treatment to over 200 patients with melanoma. Researchers want to know if TIL shrink s tumors in people with digestive tract, urothelial, breast, or ovarian/endometrial cancers. In this study, we are selecting a specific subset of white blood cells from the tumor that we think are the most effective in fighting tumors and will use only these cells in making the tumor fighting cells. Objective: The purpose of this study is to see if these specifically selected tumor fighting cells can cause digestive tract, urothelial, breast, or ovarian/endometrial tumors to shrink and to see if this treatment is safe. Eligibility: - Adults age 18-72 with upper or lower gastrointestinal, hepatobiliary, genitourinary, breast, ovarian/endometrial cancer, or glioblastoma refractory to standard chemotherapy. Design: Work up stage: Patients will be seen as an outpatient at the NIH clinical Center and undergo a history and physical examination, scans, x-rays, lab tests, and other tests as needed. Surgery: If the patients meet all of the requirements for the study they will undergo surgery to remove a tumor that can be used to grow the TIL product. Leukapheresis: Patients may undergo leukapheresis to obtain additional white blood cells. (Leukapheresis is a common procedure, which removes only the white blood cells from the patient.) Treatment: Once their cells have grown, the patients will be admitted to the hospital for the conditioning chemotherapy, the TIL cells and aldesleukin. They will stay in the hospital for about 4 weeks for the treatment. Follow up: Patients will return to the clinic for a physical exam, review of side effects, lab tests, and scans about every 1-3 months for the first year, and then every 6 months to 1 year as long as their tumors are shrinking. Follow up visits will take up to 2 days. ...

Hermansky-Pudlak Syndrome (HPS) is an inherited disease which results in decreased pigmentation (oculocutaneous albinism), bleeding problems due to a platelet abnormality (platelet storage pool defect), and storage of an abnormal fat-protein compound (lysosomal accumulation of ceroid lipofuscin). The disease can cause poor functioning of the lungs, intestine, kidneys, or heart. The major complication of the disease is pulmonary fibrosis and typically causes death in patients ages 40 - 50 years old. The disorder is common in Puerto Rico, where many of the clinical research studies on the disease have been conducted. Neither the full extent of the disease nor the basic cause of the disease is known. There is no known treatment for HPS. The purpose of this study is to perform research into the medical complications of HPS and begin to understand what causes these complications. Researchers will clinically evaluate patients with HPS of all ethnic backgrounds. They will obtain cells, blood components (plasma), and urine for future studies. Genetic tests (mutation analysis) to detect HPS-causing genes will also be conducted.<TAB>...

This study will investigate the genetic cause of Birt Hogg-Dube (BHD) syndrome and the relationship of this disorder to kidney cancer. BHD is a rare inherited condition characterized by papules, or bumps-benign tumors involving hair follicles-on the head and neck. People with BHD are at increased risk of developing kidney cancer. Scientists have identified the chromosome (strand of genetic material in the cell nucleus) that contains the BHD gene and the region of the gene on the chromosome. This study will try to learn more about: - The characteristics and type of kidney tumors associated with BHD - The risk of kidney cancer in people with BHD - Whether more than one gene causes BHD - The genetic mutations (changes) responsible for BHD Individuals with known or suspected Birt Hogg-Dube syndrome, and their family members, may be eligible for this study. Candidates will be screened with a family history and review of medical records, including pathology reports for tumors, and films of computed tomography (CT) and magnetic resonance imaging (MRI) scans. Participants may undergo various tests and procedures, including the following: - Physical examination - Review of personal and family history with a cancer doctor, cancer nurses, kidney surgeon, and genetic counselor - Chest and other x-rays - Ultrasound (imaging study using sound waves) - MRI (imaging study using radiowaves and a magnetic field) - CT scans of the chest and abdomen (imaging studies using radiation) - Blood tests for blood chemistries and genetic testing - Skin evaluation, including a skin biopsy (surgical removal of a small skin tissue sample for microscopic evaluation) - Cheek swab or mouthwash to collect cells for genetic analysis - Lung function studies - Medical photography of skin lesions These tests will be done on an outpatient basis in either one day or over 3 to 4 days. When the studies are complete, participants will receive counseling about the findings and recommendations. Individuals with kidney lesions may be asked to return periodically, such as every 3 to 36 months, based on their individual condition, to document the rate of progression of the lesions.

The research goal of this study is to obtain CD34+ hematopoietic stem cells (HSC) from peripheral blood and/or bone marrow, and Mononuclear Cells (lymphocytes and monocytes), and granulocytes (grans) from peripheral blood that will be used in the laboratory and/or in the clinic to develop new cell therapies for patients with inherited or acquired disorders of immunity or blood cells. Development of novel cellular therapies requires access to HSC, Mononuclear Cells and/or granulocytes as the essential starting materials for the pre-clinical laboratory development of gene therapies and other engineered cell products. HSC or blood cells from healthy adult volunteers serve both as necessary experimental controls and also as surrogates for patient cells for clinical scale-up development. HSC or blood cells from patients serve both as the necessary experimental substrate for novel gene therapy and cellular engineering development for specific disorders and as pre-clinical scale up of cellular therapies. Collection of cells from adult patients collected in the NIH Department of Transfusion Medicine (DTM) under conditions conforming to accepted blood banking clinical practice may also be used directly in or cryopreserved for future use in other NIH protocols that have all required regulatory approvals allowing such use. In summary, the research goal of this protocol is the collection of HSC or blood cells that may be used for both laboratory research and/or for clinical treatment in other approved protocols.

Background: Glioblastoma (GBM) is a cancer of the brain. Current survival rates for people with GBM are poor; survival ranges from 5.2 months to 39 months. Most tumors come back within months or years after treatment, and when they do, they are worse: Overall survival drops to less than 10 months. No standard treatment exists for people whose GBM has returned after radiation therapy. Objective: To find a safe schedule for using radiation to treat GBM tumors that returned after initial radiation treatment. Eligibility: People aged 18 years and older with grade 4 GBM that returned after initial radiation treatment. Design: Participants will be screened. They will have a physical exam with blood tests. A sample of tumor tissue may be collected. Participants will undergo re-irradiation planning: They will wear a plastic mask over their head during imaging scans. These scans will pinpoint the exact location of the tumor. This spot will be the target of the radiation treatments. Participants will undergo radiation treatment 4 times per week. Some people will have this treatment for 3 weeks, some for 2 weeks, and some for 1 week. Blood tests and other exams will be repeated at each visit. Participants will complete questionnaires about their physical and mental health. They will answer these questions before starting radiation treatment; once a week during treatment; and at intervals for up to 3 years after treatment ends. Participants will have follow-up visits 1 month after treatment and then every 2 months for 6 months. Follow-up clinic visits will continue up to 3 years. Follow-ups by phone or email will continue an additional 2 years.
