Active clinical trials for "Lymphoma, Non-Hodgkin"

Patients affected with non-Hodgkin's large B-cell lymphoma are treated by chemotherapy. The evaluation of the response to this treatment is made by Positron Emission Tomography (PET/CT) in many centres where this technology is available. Presently PET scans and CT scans are being performed before treatment, after 4 cycles of chemotherapy and a few months after the end of treatment. The goal of this study is to determine if it is possible to evaluate the efficiency of chemotherapy treatments after one cycle of treatment instead of waiting after 4 cycles, using a new scanner that combines PET and CT modalities. Data available from studies on these combined exams suggest that PET/CT helps to rapidly evaluate the response of the chemotherapy treatment. We also want to verify if some pathological characteristics measured from tumor cells will enable doctors to predict in advance the response to treatment.

This research study is collecting and storing tissue samples from patients with rare or cutaneous non-Hodgkin lymphoma. Collecting and storing samples of tissue from patients with cancer to test in the laboratory may help the study of cancer in the future.

Background: Residual masses on follow-up surveillance imaging are frequently detected in paediatric patients with Hodgkin's lymphoma and non-Hodgkin's lymphoma. The residual mass may consist of inflammatory, fibrous or necrotic tissue, or it could represent residual tumor. In most cases, positron emission tomography (PET) with 2-[fluorine-18]-fluoro-2-deoxy-D-glucose (FDG) is useful for distinguishing tumor from fibrosis. However, FDG is not tumor-specific, and increased accumulation of the tracer may be seen in a variety of benign entities which can give rise to false-positive or equivocal FDG PET findings. Alternatively, the uptake of 3'-deoxy-3'-[fluorine-18]-fluorothymidine (FLT) reflects cellular proliferation, and may prove to be a reliable method in resolving equivocal FDG PET findings. Indeed, several studies have demonstrated that FLT can be safely administered to children, and in some cases be more useful than FDG PET in differentiating between infection or inflammation and malignancy. This study hypothesizes that FLT PET can be used as an adjunct imaging modality in paediatric lymphoma patients with equivocal interim or post-therapy FDG PET findings, and that this technique can provide additional diagnostic information which will be useful in distinguishing fibrotic or necrotic residual mass lesions from those that may be harbouring malignancy.

This study evaluates whether tumors present in patients with cancer who are planned to get CAR T-cells have low amounts of oxygen (hypoxia). PET scans may be used to check the amounts of oxygen within areas of cancer with a special radioactive tracer called FAZA that specifically looks for areas of low oxygen. This study is being done to help researchers determine how the amount of oxygen within areas of cancer affect how well CAR T-cells kill cancer cells.

The primary purpose of this retrospective study was to investigate the influence of methylenetetrahydrofolate reductase (MTHFR) C677T/A1298C polymorphism on the survival of pediatric patients with Non-Hodgkin lymphoma (NHL) treated with modified NHL-BFM95 protocol in south China.

The development of new diagnostic tools and targeted therapy have significantly improved the management of non-Hodgkin's malignant lymphomas and thus their long-term prognosis. However, in the study of improved patient management, survival is not the only measurable indicator and preservation of quality of life is an essential component. In addition, there is little existing data regarding the determinants of quality of life in patients with diffuse large B-cell lymphoma (DLBCL) or follicular lymphoma (FL) in the general population in France.

The primary purpose of the study is to quantify participants' demographic parameters, country standard therapies, treatment patterns and outcomes among participants with chronic lymphocytic leukemia (CLL), multiple myeloma (MM) and non-Hodgkin's lymphoma (NHL) in oncology concentration hospitals in Latin America.

To estimate the incidence of febrile neutropenia in patients with breast cancer and non-Hodgkin's lymphoma receiving high (> 20%) FN-risk chemotherapy and pegfilgrastim primary prophylaxis.

Prospective multicenter observational non-interventional study to assess routine clinical practice of Bendamustine use in the second line therapy of relapsed or refractory indolent B-cell non-Hodgkin's lymphoma

This purpose of this study it to characterize the walking patterns of children diagnosed with Acute Lymphoblastic Leukemia (ALL)and Lymphoblastic Lymphoma (LL) at different times in the treatment protocol and after completion of treatment. Their walking patterns will be compared to children without ALL or LL to see if their walking patterns are different at specific times in their treatment program or up to 10 years after completion of their treatment. The investigators will gather data by observing how the child walks, runs, hops on one foot and climbs stairs and by recording walking patterns on a pressure sensitive mat. The investigators will compare this data to children without ALL and LL.
