Active clinical trials for "Lymphoma, Non-Hodgkin"

Lymphomas are classified as Hodgkin's or non-Hodgkin's lymphomas, of which especially the latter represent a heterogeneous group with varying patterns of prognosis, biological behaviour and response to treatment. 18F-FDG PET/CT is useful for staging and response monitoring but has the disadvantage of associated radiation exposure which may not be desirable for young patients. Advanced MRI techniques including diffusion weighted imaging (DWI) are increasingly used for improved lesion detection and characterisation of lymphomas and in the whole-body mode offer a promising radiation-free alternative to CT. Molecular imaging in turn is important in theranostics medicine where detection of therapeutic target is essential. The concept of theranostics has been successfully adapted to management of neuroendocrine tumors (NET) where peptide receptor radiotherapy (PRRT) is offered to patients progressing on treatment with long-acting somatostatin analogues. Recently in the investigator's hospital a case of diffuse large B-cell lymphoma (DLBCL) was initially misdiagnosed as NET because of high uptake of 68Ga-DOTANOC in pancreatic tumor at PET/CT. A PubMed search revealed a similar case report in bronchial tumor which turned out to be DLBCL (Jain et al. Clin Nucl Med 2014;39:358-359). Bearing these two cases in mind the investigators now aim to systematically study somatostatin receptor status (ssr) by measuring uptake of 68Ga-DOTANOC with PET/CT in patients with newly diagnosed non-Hodgkin's and Hodgkin's lymphoma. The imaging findings will be compared to immunohistochemically determined ssr-subtypes 2,3 and 5 obtained from pre-treatment fresh tumor samples and 18F-FDG PET/CT which is part of standard diagnostic evaluation. Furthermore, whole-body MRI with DWI will be performed before, during and after chemotherapy to define the most sensitive and specific imaging method appropriate for routine diagnosis and follow-up. This study has potential implications for future response monitoring and follow-up imaging techniques in patients with malignant lymphoma and provides additional biologic characterization which may be useful for novel therapeutic approaches such as PRRT.

The aim of the trial is to test whether adding 6 injections of rituximab to standard "Lymphome malin B" LMB chemotherapy regimen improves the Event Free Survival (EFS) compared with LMB chemotherapy alone in children / adolescents with advanced stage B-cell Non-Hodgkin Lymphoma (NHL) / B-Acute Leukemia (B-AL)(stage III and LDH > Nx2, any stage IV or B-AL).

The purpose of this study is to find out whether a new device can help obtain more accurate CT and PET scans of the lungs and chest tumors and the liver and liver tumors to help in delivering radiation therapy. When we breathe, the amount of air in the lung changes. Lung tumors may also move during breathing. Liver tumors may also move with breathing; as the lungs inflate, the liver can be pushed down. A CT scan (a special type of X-ray) is routinely obtained as part of planning for lung or liver radiation therapy. Since patients breathe during this CT scan and their lung or liver tumors move, these CT scans can sometimes be inaccurate. We are now testing a device to only obtain the CT and an additional PET scan while patients are breathing in or out. This will hopefully allow us to deliver radiation with more accuracy.

This is an open-label, single-center Phase 1/2 study with a dose-escalation phase (Part 1) and a cohort expansion phase (Part 2) in patients with relapsed or refractory (R/R) B-cell non-Hodgkin lymphoma (B-NHL).

This is a diagnostic prospective multicenter study. This study will be conducted in 32 centers of the Société Française des Cancers et Leucémies de l'Enfants et de l'Adolescent (SCFE) in patients with non-Hodgkin lymphoma and treated according to recommendations of the SFCE for each type of non-Hodgkin lymphoma. All patients will have a PET / CT associated with conventional imaging time of remission assessment. Histological examination of residual tumor will be conducted whenever practicable in patients with pathologic residual image on conventional imaging and / or PET / CT. A central review of conventional imaging examinations and PET / CT will be performed independently from each other. Moreover, whenever possible, patients will have a PET / CT at diagnosis and an early PET / CT (between J8 and J28 according to the type of lymphoma and toxicities due to treatment). The results of the early PET / CT should not lead to treatment modifications. In case of residual tumor at remission assessment, therapeutics changes as recommended therapeutic protocols will be based on histologic findings and not on the results of PET / CT alone.

The purpose of this study is to evaluate progression free survival, transplant-related morbidity (TRM) at day +100 and at +365, overall survival and incidence of acute and chronic GVHD in refractory/early relapsed aggressive B-cell non Hodgkin lymphomas patients treated with allogeneic Transplantation after a conditioning with Thiotepa, Busulfan and fludarabin.

In this study the treatment process will be closely monitored using a novel imaging technology, a PET/CT scanner. PET stands for Positron Emission Tomography and in this case it will be combined with a conventional x-ray Computerized Tomography (CT) scan. This is not a study of any particular form of treatment. The treatment you receive will be the most appropriate standard treatment whether you are in the study or not. The goal of radiation therapy is to deliver a given amount of radiation dose to the area where there is a lymphoma tumour. We are doing this study to see which part of the tumour reacts to the radiation treatment, and which part does not react, by monitoring the progress of your treatment with a combined PET/CT scan. In particular, changes of the size and shape of the tumour that occur during the treatment can be detected and will be visible on the images. These images will be thoroughly analysed. The ability of the PET/CT scanner to detect these changes during a course of radiation treatment will be the subject of this study. We will also be able to see if this information will eventually relate to or predict whether lymphoma tumours will be completely eradicated by the treatment.

The study of Dariniparsin (ZIO-101-C) in Advanced Solid Tumors and Non-Hodgkin's Lymphomas

Phase II study for treatment of patients with relapsed or primary refractory aggressive B- cell NHL and anthracycline chemotherapy pretreatment, who received or did not qualify for autologous stem cell transplantation.

Hepatitis B (HBV) reactivation and hepatitis flare induced by cytotoxic chemotherapy is common in cancer patients who have chronic HBV infection. Lymphoma patients who had previous infected by HBV but negative for HBsAg have a the risk of HBV reactivation during chemotherapy, but prophylactic antiviral treatment is not a routine by current American Association for the Study of Liver Diseases (AASLD) guideline. Prophylactic entecavir might reduce the risk of HBV reactivation in such patients.
