Lymphatic Diseases

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 Foo
