Filter by:T-cell Non-Hodgkin's lymphomas are a group of cancers that are usually treated with chemotherapy, radiation therapy, or occasionally surgery. T-cell lymphomas are relatively uncommon and therefore not well studied. Treatment approaches are patterned after the more common B-cell lymphomas. T-cell lymphomas are more likely to relapse following standard therapy than are B-cell lymphomas. New therapies are needed for T-cell lymphomas. In this study, we will administer the drug called lenalidomide as a pill to patients with T-cell lymphoma. The goals are to determine if the drug can induce regression of the cancer, and to determine if the treatment is well tolerated in this patient group. This study will take place at six cancer centres across Canada.
Primary Objective: - To determine the toxicity profile and tolerability of alemtuzumab (Campath) when administered in combination with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) chemotherapy (C-CHOP) in patients with T-cell, null-cell and NK-cell lymphomas. Secondary Objectives: - To evaluate response rate, overall survival, and disease-free survival in patients with T-cell, null-cell, and NK-cell lymphomas treated with Campath + CHOP chemotherapy. - To assess the incidence of cytomegalovirus (CMV) reactivation in patients with these lymphomas treated with the Campath + CHOP combination. - To determine features which might be predictive of resistance to treatment or predictive of relapse, including the absence of glycosylphosphatidylinositol (GPI)-linked proteins.
Peripheral T cell lymphoma and advanced cutaneous T cell lymphomas are aggressive and refractory diseases that are generally treated with chemotherapy. Despite current treatment modalities, only a subset of patients will be cured by the treatment. In this study, four chemotherapeutic agents (L-asparaginase, Methotrexate, Doxil, and Prednisone) will be administered in a combination regimen for patients with relapsed or refractory Peripheral and/or advanced cutaneous T cell lymphoma. Each one of these individual drugs have been shown to have activity to lymphomas. The objective of the study is to determine if the combination of these chemotherapy agents results in higher response and cure rates in this patient population. This will be a single institutional study which will included 32 patients in the Peripheral T cell lymphoma group and 32 patients in the Cutaneous T cell lymphoma group.
This protocol is being submitted to consolidate, update, and expand two previously approved protocols (77-C-0066 and 82-C-0044) into a single protocol. The purpose of this study is to examine the factors involved in the regulation of the immune system of healthy individuals and to define the abnormalities in this regulation that underlies the immunological disorders of patients with a variety of immunodeficiency and malignant disorders. The studies will include the ex vivo phenotypic and functional analysis of the network of cells involved in humoral and cellular immune responses, and in vivo testing for the capacity to make delayed-type hypersensitivity and humoral responses following immunization with a variety of antigens. Individuals to be studied will include patients with a variety of malignancies and patients with primary and secondary immunodeficiency disorders. Selected family members or family members known to be genetic carriers of certain immunodeficiency diseases as well as normal, unrelated individuals will also be studied. A small number of procedures will be used including analysis of blood obtained by phlebotomy, apheresis, skin testing and recall antigens and immunization to assess humoral immunity....
