Active clinical trials for "Lymphoma"

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Giving radiation therapy in different ways may kill more tumor cells. It is not yet known which regimen of radiation therapy is more effective for non-Hodgkin's lymphoma. PURPOSE: Randomized phase III trial to compare the effectiveness of radiation therapy to the involved area with or without total-body irradiation in treating patients who have low-grade stage I or stage II non-Hodgkin's lymphoma that has not previously been treated.

Phase I trial to study the effectiveness of radiolabeled monoclonal antibody therapy with or without peripheral stem cell transplantation in treating patients who have recurrent or refractory lymphoma. Radiolabeled monoclonal antibodies can locate cancer cells and deliver radioactive tumor-killing substances to them without harming normal cells. Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by anticancer therapy

RATIONALE: Cyclosporine may help the immune system slow the growth of angioimmunoblastic T-cell lymphoma. PURPOSE: This phase II trial is studying how well cyclosporine works in treating patients with recurrent or refractory angioimmunoblastic T-cell lymphoma.

Currently there is no one standard of care for older patients with Non-Hodgkin's Lymphoma (NHL). The study will examine the tolerability and feasibility to the combination of Cyclophosphamide, Pegylated Liposomal Doxorubicin, Vincristine, Prednisone (CDOP) plus Rituximab.

This phase I trial is studying the side effects and best dose of giving tanespimycin together with bortezomib in treating patients with advanced solid tumors or lymphomas. (Accrual for lymphoma patients closed as of 11/27/09) Drugs used in chemotherapy, such as tanespimycin, work in different ways to stop cancer cells from dividing so they stop growing or die. Bortezomib may stop the growth of cancer cells by blocking the enzymes necessary for their growth. It may also increase the effectiveness of tanespimycin by making cancer cells more sensitive to the drug. Combining tanespimycin with bortezomib may kill more cancer cells.

The purpose of this study is to determine the optimal dose of subcutaneous CAMPATH when used in combination with rituximab for patients with relapsing or refractory, low-grade or follicular, CD-20-positive, B-Cell non-Hodgkin's Lymphoma. Safety will be the primary objective of phase I, while the primary objective of phase II will be to determine overall response.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. PURPOSE: Phase I trial to study the effectiveness of 506U78 in treating patients who have hematologic cancer and kidney or liver impairment.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. It is not yet known which combination chemotherapy regimen is more effective in treating non-Hodgkin's lymphoma. PURPOSE: Randomized phase II/III trial to compare the effectiveness of combination chemotherapy with or without etoposide in treating older patients who have non-Hodgkin's lymphoma that has not been previously treated.

MiRNAs are noncoding RNAs (ncRNAs) that drive post-transcriptional negative regulation of gene expression by promoting the degradation or translational blockade of their target mRNAs. MiRNAs are 21-24-nucleotide-long RNA molecules that are processed from longer RNA precursors (pri-miRNAs) , and either the 5' or the 3' strand of the mature miRNA duplex is loaded into the Argonaute (AGO) family of proteins to form a miRNA-induced silencing complex (miRISC) When bound to AGO proteins, mature miRNAs destabilize or inhibit the translation of partially complementary target mRNAsMiRNA-124 has been shown to be a tumor suppressor, and a decrease in its expression level is typical of tumors of various localization, but there is no evidence of the role of miRNA-124 in the development of NHL . There are a number of studies reflecting the involvement of miRNA-124 in hematopoiesis. Liu et al. showed that miRNA-124 regulates Tip110 that is involved in the differentiation of hematopoietic stem cellsThe let-7 family has been shown to influence the pathogenesis of a variety of hematological malignancies through the changing expression of a number of oncogenic pathways, particularly those related with MYC and that might affect hematopoietic carcinogenesis through the modulation of inflammatory pathways

Primary central nervous system (CNS) lymphomas represent 5% of primary brain tumors. More than 90% of them are diffuse large B-cell lymphomas. [18F]-Fluorodeoxyglucose positron emission tomography (PET-[18F]-FDG) is the gold standard for imaging systemic lymphomas, but its application in primary CNS lymphoma is compromised by the limited specificity of brain fixations and the high uptake of [18F]-FDG in healthy brain tissue. [18F]-Fludarabine is a new radiopharmaceutical developed for PET imaging of lymphomas. Preclinical studies indicate a restricted binding specificity to lymphoid tissue compared to [18F]-FDG and an ability to detect residual lymphoma disease after treatment. A pilot study in humans shows good agreement of its binding with tumor sites in systemic lymphoma and superior tumor contrast to [18F]-FDG. Finally, a recent preclinical study shows a binding ratio in brain lymphoma 3 times higher than that of healthy brain tissue in mouse models of primary CNS lymphoma, whereas in mouse models of high-grade glial tumors, the binding level is very low, comparable to that of healthy tissue (background). Investigators hypothesize that [18F]-Fludarabine could be the radiopharmaceutical of choice for the diagnosis and monitoring of primary CNS lymphomas in PET. The main objective of the study is to characterize the cerebral distribution and [18F]-Fludarabine uptake in newly-diagnosed primary CNS lymphomas before surgery, chemotherapy or radiotherapy, using PET-MR imaging.
