Filter by:The primary aim of this study is to investigate and test whether the use of combined indocyanine green (ICG) lymphography and ultra high frequency ultrasonography can correctly identify lymphatic vessels and venoles in close proximity to each other, for identification prior to lymphovenous anastomosis (LVA) surgery.
Adult T-cell leukemia/lymphoma (ATLL) is a rare form of cancer found mostly among people from the Caribbean islands, Western Africa, Brazil, Iran, and Japan. Most cases of this disease in the United States occur along the East Coast due to emigration from the Caribbean islands. There is currently no standard treatment for ATLL. Research shows that patients who go into first time remission (respond completely or partially to treatment) and have a bone marrow transplant have the best outcomes. Traditional chemotherapy treatments have generally not worked well in patients with ATLL. Additionally, not all patients will be eligible for a bone marrow transplant. The purpose of this study is to see how well individuals with ATLL respond to an investigational cancer treatment. This investigational treatment combines a drug called brentuximab vedotin with a standard chemotherapy treatment made up of cyclophosphamide, doxorubicin, etoposide, and prednisone. This treatment is considered investigational because it is not approved by the United States Food and Drug Administration (FDA) for the treatment of ATLL. Brentuximab vedotin, also known as Adcetris, is approved by the United States Food and Drug Administration (FDA) for treatment of certain types of lymphomas, including peripheral T-cell lymphomas when combined with cyclophosphamide, doxorubicin, and prednisone in patients whose cancer cells express a type of marker called CD30. Brentuximab vedotin is an antibody that also has a chemotherapy drug attached to it. Antibodies are proteins that are part of the immune system. They can stick to and attack specific targets on cancer cells. The antibody part of brentuximab vedotin sticks to a target called cluster of differentiation 30 (CD30) that is located on the outside of the cancer cells. Normal cells have little or no CD30 on their surface. ATLL cancer cells often have a larger amount of CD30 on their surface than normal cells. However, CD30 is found in different amounts on ATLL cancer cells. This study will also test the amount of CD30 found on each participant's cancer cells. Researchers will be looking to see if the response to the study treatment varies based on the amount of CD30 found on the outside participants' cancer cells. In another study, brentuximab vedotin was combined in another study with cyclophosphamide, doxorubicin, and prednisone. The study included patients with various types of T-cell lymphomas. Two of the patients enrolled in that study had ATLL. Both had a complete response (no evidence of disease). The researchers in this study (LCCC 1637) have added etoposide to the combination of brentuximab vedotin with cyclophosphamide, doxorubicin, and prednisone. They predict that the addition of etoposide will improve patient outcomes. Research shows that etoposide helps improve outcomes in patients with certain types of T-cell lymphomas who undergo chemotherapy treatment. This investigational combination of brentuximab vedotin with cyclophosphamide, doxorubicin, etoposide, and prednisone is called BV-CHEP.
The body has different ways of fighting infection and disease. No single way seems perfect for fighting cancer. This research study combines two different ways of fighting disease: antibodies and T cells. Antibodies are proteins that protect the body from disease caused by bacteria or toxic substances. Antibodies work by binding those bacteria or substances, which stops them from growing and causing bad effects. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells, including tumor cells or cells that are infected. Both antibodies and T cells have been used to treat patients with cancers. They both have shown promise, but neither alone has been sufficient to cure most patients. This study is designed to combine both T cells and antibodies to create a more effective treatment. The treatment that is being researched is called autologous T lymphocyte chimeric antigen receptor cells targeted against the CD30 antigen (ATLCAR.CD30) administration. In previous studies, it has been shown that a new gene can be put into T cells that will increase their ability to recognize and kill cancer cells. A gene is a unit of DNA. Genes make up the chemical structure carrying the patient's genetic information that may determine human characteristics (i.e., eye color, height and sex). The new gene that is put in the T cells in this study makes a piece of an antibody called anti-CD30. This antibody floats around in the blood and can detect and stick to cancer cells called lymphoma cells because they have a substance on the outside of the cells called CD30. Anti-CD30 antibodies have been used to treat people with lymphoma, but have not been strong enough to cure most patients. For this study, the anti-CD30 antibody has been changed so that instead of floating free in the blood part of it is now joined to the T cells. Only the part of the antibody that sticks to the lymphoma cells is attached to the T cells instead of the entire antibody. When an antibody is joined to a T cell in this way it is called a chimeric receptor. These CD30 chimeric (combination) receptor-activated T cells seem to kill some of the tumor, but they do not last very long in the body and so their chances of fighting the cancer are unknown. The purpose of this research study is to determine a safe dose of the ATLCAR.CD30 cells that can be given to subjects after undergoing an autologous transplant. This is the first step in determining whether giving ATLCAR.CD30 cells to others with lymphoma in the future will help them. The researchers also want to find out what side effects patients will have after they receive the ATLCAR.CD30 cells post-transplant. This study will also look at other effects of ATLCAR.CD30 cells, including their effect on your cancer and how long they will survive in your body.
This study focuses on three different lesions: pancreatic cysts, lymph nodes near the gastrointestinal tract and pancreatic masses. On one hand, the results obtained during previous studies are more advanced for the assessment of the diagnostic performance of Cellvizio needle-based Confocal Laser Endomicroscopy (nCLE) system for Pancreatic cysts. Safety and technical feasibility have already been performed, and an interpretation criteria classification exists. On the other hand, results for pancreatic masses and Lymph nodes are less developed. The study therefore comprises two sub-studies, one on the pancreatic cysts, and another on pancreatic masses and lymph nodes. 1. Cysts The primary hypothesis of the study is that using nCLE in addition to EUS-FNA and tissue sampling allows better characterization of pancreatic cysts and improves appropriate therapeutic decision-making. For physicians, integrating nCLE into the diagnostic algorithm of pancreatic cysts could impact patient management by : - Ruling out malignancy for patients with benign appearing nCLE images. - Characterizing more malignant tumors in the pancreas. 2. Pancreatic masses and Lymph nodes The primary hypothesis of the study is that in vivo imaging of lymph-nodes near the gastrointestinal tract and pancreatic masses during EUS-FNA procedures is feasible and that descriptive criteria can be defined to further differentiate the different types of lesions.
