Active clinical trials for "Lymphoma"

Granulocyte colony stimulating factors (GCSFs) stimulate the level of white blood cells, specifically neutrophils. GCSF support for patients receiving chemotherapy was shown to decrease the rate of fever during low neutrophil count (neutropenia), and in some cancer types may decrease mortality. Pegfilgrastim is a pegylated form of the GCSF named filgrastim. Pegfilgrastim is used to stimulate bone marrow to produce more neutrophils to fight infection in patients undergoing chemotherapy. It has a much longer half-life than the parent filgrastim. It is removed from the body within the neutrophils. According to the American Society of Clinical Oncology 2006 guidelines pegfilgrastim should be given 24 hours after the completion of chemotherapy i.e.before neutrophil count starts to drop. Therefore it is cleared before and after neutropenia. Comparative low quality studies suggest that deferring pegfilgrastim delivery until neutrophil counts start dropping may result in improved its efficacy. This was further tested in a few small randomized controlled trials (high quality studies, considered the "gold standard" of studies) in different settings (including first chemotherapy for lymphoma, and solid cancer) with inconsistent results. Pegfilgrastim (given 24 hours after completion of chemotherapy) is a standard part of any salvage chemotherapy for patient with refractory or relapsed aggressive lymphoma. The investigators plan a randomized controlled trial comparing the efficacy of pegfilgrastim given 72 hours (day +3) vs. 24 hours (day +1) after completion of salvage chemotherapy in patients with refractory or relapsed aggressive lymphoma. The investigators will evaluate whether that change of pegfilgrastim schedule affects the risk of fever during neutropenia, neutrophil count, length of hospitalization, mortality, and safety.

The present study aims to further optimize a whole-body Diffusion-Weighted Magnetic Resonance Imagery (DW-MRI or DWI) protocol on 3 Tesla MR and/or new system combining 3Tesla MR and Positron Emission Tomography (PET), to develop and validate an automated whole-body parametric image analysis algorithm, and to determine the added value of whole-body DWI to Fluorodeoxyglucose-PET for the management of lymphoma patients.

This prospective observational study will evaluate the safety and efficacy of first-line rituximab maintenance therapy in participants with follicular non-Hodgkin's lymphoma. Participants initiated on rituximab maintenance therapy according to the standard of care and in line with the current summary of product characteristics will be followed for a maximum of 3 years or until disease progression occurs.

The investigators hypothesized that Non Hodgkin lymphoma is using T helper 2 pathways. So that the investigators decided to study of cytokines related to T helper 2 pathways. It is well known that parasites and allergic situations also use T helper 2 pathways. Because that the investigators excluded the patients have parasites and allergic situations. All the patients were over 18. The investigators included the patients with non Hodgkin lymphoma which new diagnosed. It is observational study. The investigators took blood before chemotherapy and four months later. The investigators did not interfere with which chemotherapy will be given to patients. This decision was belong to hematologist or oncologist who will treat the patient.

While thoracic radiation therapy (TRT) has been a primary component in successful treatment of a variety of childhood and adult cancers, the exposure to this treatment has been associated with significant cardiovascular and pulmonary morbidity in long-term survivors. Within non-cancer populations, cardiovascular and pulmonary morbidity is associated with increased risk for cerebral vascular accidents (CVAs), accelerated brain atrophy and neurocognitive impairment. Patients with chronic heart disease demonstrate problems with attention, processing speed, memory, and executive functions. Chronic pulmonary disease also increases the risk of stroke, leukoencephalopathy, and neurocognitive impairment in non-cancer populations. The investigators propose to examine indices of brain integrity, including neurocognitive performance and brain MRI/MRA, in long-term adult survivors of Hodgkin lymphoma (HL) treated with thoracic radiation and no direct central nervous system therapy. OBJECTIVES: To evaluate brain integrity in adult survivors of childhood HL treated with thoracic radiation therapy. To identify therapeutic factors associated with brain integrity in adult survivors of childhood HL who are at risk for cardiac and pulmonary morbidity. To examine associations between cardiac, vascular and pulmonary health and brain integrity in adult survivors of childhood HL treated with thoracic radiation.

The purpose of this study is to establish a model which can predict the treatment outcome and the risk of treatment-related morbidity in patients with lymphoma.

The purpose of this study is to evaluate whether 18F-FDG PET/CT-based prognostic model of PTCL can predict disease progression

The purpose of this study is to collect data from patients by social media and self-report on the adverse events and outcomes happened with patients with extranodal natural killer/T-cell lymphoma, nasal type, who are treated outside of clinical trials in China.

The purpose of the study (retrospective and prospective) is to describe participant and disease characteristics and treatment pattern of Bortezomib treated mantle cell lymphoma (MCL) participants in China.

Evaluate if Y90 Ibritumomab Tiuxetan Radioimmunotherapy in addition to standard high dose chemotherapy followed by autologous stem cell transplant could improve prognosis in patients affected by relapsed/refractory aggressive non Hodgkin lymphoma
