Peripheral T-Cell LymphomasNon-Hodgkin Lymphoma

Peripheral T-cell lymphomas (PTCLs) are neoplasias from post-thymic T-cells at different stages of differentiation and are a heterogeneous group of malignancies which present with different morphological patterns, phenotypes, and clinical presentations. These tumours have a striking epidemiological distribution with a lower incidence in Western countries than in Asia. In Korea, PTCLs including T- or natural killer (NK)-cell lymphomas constitute approximately 25 to 35% of all non-Hodgkin's lymphomas. This incidence is quite similar to that of other Eastern Asian countries, including Japan, Hong Kong, and China. Recent studies suggest that the T-cell phenotype is an independent significant prognostic factor, with PTCLs having one of the lowest overall survival and failure-free survival rates. Based on the investigator's experience, the overall complete remission rate was 61.2% (95% confidence interval [CI]: 48.5-72.8%) and the 5-year probability of failure-free survival was 33.5%. Median survival of all patients was 45 months (range 0-64+ months) and the 5-year probability of survival was 36.2%. Rassidakis et al. reported that expression of pro-apoptotic proteins BAX and BCL-XS, may explain the poor response of many types of PTCL to standard chemotherapy. To overcome such poor outcome, the optimal therapy for PTCLs remains to be defined. However, because of the rarity of the disease in Western countries, only a few trials have been reported. Bortezomib (Velcade) is a modified dipeptidyl boronic acid, and a reversible inhibitor of the chymotrypsin-like activity of the 26S proteosome. Bortezomib may induce tumor cell apoptosis or decreased bcl-2 associated drug resistance. Through phase II studies, single agent bortezomib in patients with relapsed indolent and mantle cell lymphomas showed its activity. And also preliminary data indicate that bortezomib can be safely administered in combination with dose adjusted etoposide, prednisolone, vincristine, cyclophosphamide and doxorubicin (EPOCH) chemotherapy. Therefore, it can be possible to improve the poor outcome of patients with PTCLs by a combination of cyclophosphamide, doxorubicin, vincristine, prednisolone (CHOP) with bortezomib as a first-line therapy. Primary Hypothesis: Based on the clinical trials and experimental data, bortezomib can overcome pro-apoptotic proteins BAX and BCL-XS induced drug resistance.

A Phase II Study of Nasal NK/T-cell Lymphoma

Lymphoma

To determine whether adding combinational chemotherapy concurrently to conventional radiation will improve the response rate, event-free survival, and overall survival. To test the dose intensity and toxicity of chemotherapy in concurrence with radiation. To detect the blood EBV DNA level in Chinese Nasal NK/T-cell lymphoma patients and correlate to the treatment response and prognosis.

3-AP and Gemcitabine in Treating Patients With Advanced Solid Tumors or Lymphoma

Anaplastic Large Cell LymphomaAngioimmunoblastic T-cell Lymphoma58 more

This phase I trial is studying the best dose of 3-AP and the side effects of giving 3-AP together with gemcitabine in treating patients with advanced solid tumors or lymphoma. Drugs used in chemotherapy, such as 3-AP and gemcitabine (GEM), work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. 3-AP may help gemcitabine kill more cancer cells by making the cells more sensitive to the drug. 3-AP may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Study of Bortezomib Combined With ACVBP in Peripheral T-cell Lymphoma

Peripheral T-cell Lymphoma

The purpose of this study is to determine the efficacy and the safety profile and toxicity of a combination of Velcade™ (bortezomib) with a standard chemotherapy regimen (ACVBP [doxorubicin, cyclophosphamide, vindesine, bleomycin, and prednisone]) in the treatment of previously untreated patients with peripheral T-cell lymphoma (PTCL).

Study of ONTAK (Denileukin Diftitox) in Previously Treated Cutaneous T-Cell Lymphoma Patients

LymphomaT-Cell3 more

The purpose of this study is to provide an opportunity for patients who exhibit progressive disease while receiving placebo on the companion 93-04-11 study to receive ONTAK. It is also designed to determine the effectiveness of ONTAK in Cutaneous T-cell Lymphoma (CTCL) patients whose tumors do not express CD25.

Low-Dose Total Body Irradiation and Donor Peripheral Blood Stem Cell Transplant Followed by Donor...

Adult Nasal Type Extranodal NK/T-cell LymphomaAnaplastic Large Cell Lymphoma34 more

This pilot clinical trial studies low-dose total body irradiation and donor peripheral blood stem cell transplant followed by donor lymphocyte infusion in treatment patients with non-Hodgkin lymphoma, chronic lymphocytic leukemia, or multiple myeloma. Giving total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. When healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Once the donated stem cells begin working, the patient's immune system may see the remaining cancer cells as not belonging in the patient's body and destroy them. Giving an infusion of the donor's white blood cells (donor lymphocyte infusion) may boost this effect.

Accelerated Phase Chronic Myelogenous LeukemiaAcute Undifferentiated Leukemia181 more

This clinical trial studies the side effects and best dose of giving fludarabine and total-body irradiation (TBI) together followed by a donor stem cell transplant and cyclosporine and mycophenolate mofetil in treating human immunodeficiency virus (HIV)-positive patients with or without cancer. Giving low doses of chemotherapy, such as fludarabine, and TBI before a donor bone marrow or peripheral blood stem cell transplant helps stop the growth of cancer or abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine (CSP) and mycophenolate mofetil (MMF) after the transplant may stop this from happening.
