Active clinical trials for "Lymphoma"

Diffuse large B-cell lymphomas (DLBCLs) represent 25 to 30% of adult non-Hodgkin lymphomas in western countries. DLBCLs are aggressive cancer but potentially curable with multi-agent chemotherapy. Whereas R-CHOP regimen has led to a marked improvement in survival, this disease remains a biologically heterogeneous entity. New therapeutic strategies are required including identification of patients' subgroups with different prognostic. This project is based on BMS_LyTrans and Goelams 075 clinical trial. A study of whole blood transcriptome in 75 DLBCL patients and in 87 controls showed that PD-L1 (CD274) gene was overexpressed in DLBCL patients. Preliminary results demonstrated that PD-L1 is detected in plasma of DLBCL patients with a significantly higher concentration than in controls. This protein was selected as a potential biomarker because of its established role in anti-tumoral immunity. Interaction between PD-L1 and its receptor PD-1 is known to inhibit activation of immune responses by inducing T-lymphocytes anergy and/or apoptosis. Moreover, a direct involvement of PD-L1 in the protection of cancer cells from lysis by activated T lymphocytes has been demonstrated. PD-L1 expression has been described in several solid tumours, including ovary cancer, breast cancer, colon cancer, renal cell carcinoma, non-small cell lung carcinoma and in hematological malignancies such as T-NHL, MM and Hodgkin's lymphoma. Furthermore the expression of PD-L1 by tumour cells is associated with poor prognosis. The blockade of PD-L1/PD-1 axis may represent a novel therapeutic approach in aggressive cancers. These first results incite to identify the cells releasing soluble PD-L1 and to investigate its role in the anti-tumoral immunity in DLBCL patients. The aim of this study is to identify cells producing soluble PD-L1 in DLBCL patients at diagnosis in comparison to others tumours known to express PD-L1 (metastatic breast cancer, Hodgkin's lymphoma, non-small cell lung cancer).

The aim of this study is to prove the superiority of entecavir over lamivudine for preventing the risk of hepatitis B virus reactivation in patients with non-Hodgkin lymphoma on CHOP/R-CHOP.

The purpose of this study is to provide patients who have relapsed or refractory Mantle Cell Lymphoma (MCL) with early access to an investigational medication called ibrutinib (PCI-32765) and to collect safety information about the drug.

In this study the investigators would like to describe FDG-PET/CT responses in patients who are receiving CART-19 immunotherapy for Follicular Lymphoma (FL), Diffuse Large B-cell Lymphoma (DLBCL), and Mantle Cell Lymphoma (MCL) as part of UPCC #13413. Subjects will undergo two FDG-PET/CTs. One performed within 6 weeks of CART-19 infusion and a repeat scan at about 1 month after infusion.

RIPAL is a prospective cohort study, which main goal is to define T and B immune repertoire diversity and magnitude in patients with non-Hodgkin lymphoma of high and low grade and chronic lymphocytic leukemia before and after treatment, and to evaluate the association of these parameters with clinical patient data and outcomes.

Whole body diffusion-weighted imaging is a functional magnetic resonance imaging technique that characterizes tissue by probing changes in water diffusion secondary to differences in the tissue microstructure. These changes in water diffusion result in differences in signal intensity on diffusion-weighted-images that are quantified with the apparent diffusion coefficient (ADC). In malignant lesions, the extravascular extracellular space (EES) will be diminished, due to the increased number of cells. This will restrict water diffusion, identified by increased signal intensity (SI) on native DWI images and low ADC. Several studies indicate the value of DWI for differentiation of benign and malignant lymph nodes, detection of tumor recurrence and for ADC-based prediction of treatment outcome in various solid tumours (Koh DM et al, Am J Roentgenol 2007). Patients with a new diagnosis of Hodgkin or Non-Hodgkin Lymphoma (only diffuse large B-cell lymphoma, follicular lymphoma, mantle cell lymphoma and PTLD) will be included in the study. These patients will receive a WB-DWI scan before treatment, once or twice during treatment (depending on the type of lymphoma) and after the completion of the treatment. The MRI scan will be performed on a 3 Tesla-MRI system without contrast administration and without exposing the patient to radiation. Whole body diffusion-weighted images will be prospectively interpreted by two experienced radiologists, blinded to all clinical and imaging data. Findings will be correlated to FDG-18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose , biopsies performed in clinical routine (bone marrow always - soft tissue lesions if indicated) and imaging follow-up. The purpose of this study is: to evaluate Whole body diffusion-weighted imaging for staging of lymphoma to evaluate Whole body diffusion-weighted imaging as an early predictive biomarker for treatment outcome to evaluate Whole body diffusion-weighted imaging for differentiating residual tumor from post therapy changes

Mediastinal irradiation for treatment of malignancy increases the risk for coronary artery disease (CAD), while diabetes mellitus or other known risk factors can be absent at the time of the first coronary event. Radiation-induced atherosclerosis affects the coronary ostia and proximal coronary segments, or causes diffuse microvascular damage. Younger patients and those exposed to high radiation doses (> 35 Gy) have a higher risk for developing premature CAD and likely may benefit from coronary assessment. A novel hybrid imaging technique that combines SPECT and CTCA has been shown to overcome the individual pitfalls and the diagnostic challenges of stand-alone SPECT and CCTA, improve the lesion detectability and sensitivity in patients with balanced diffuse lesions as well as the specificity and mainly PPV of CTCA. The aim of the study is to perform hybrid SPECT/CTCA in asymptomatic patients with HL who have received radiotherapy to the mediastinum in order to allow an early diagnosis of hemodynamically significant CAD that will need further therapeutic interventions.

This follow-up protocol is designed to evaluate participants who have previously been lymphoma patients treated on approved clinical studies of the National Institutes of Health.

The purpose of this study is to define if flow cytometry has more sensitivity for detecting neoplastic cells in cerebrospinal fluid versus conventional cytology.

Patients with inflammatory bowel disease (IBD) may be at increased risk of lymphoma. The majority of lymphomas in patients with IBD occur in areas of active inflammation. The relationship between IBD and lymphoproliferative disease is however unclear, since both chronic inflammation as well as medications used to treat IBD (especially immunosuppressives - Azathioprine or 6-MP - and anti-TNF alpha agents) have been associated with increased risk of lymphoma. We plan to study the association between IBD and lymphoma in a large, mixed, community based and referral population from the IBD database at Indiana University.
