Active clinical trials for "Lymphoma"

Participants who are scheduled to have an endo bronchial ultrasound (EBUS) trans bronchial needle aspiration (TBNA) will provide additional samples. These samples will then be sent to Imperial College London to see whether a cell line can be grown. If growth is successful then the samples will be returned to our pathology department to see if grading is possible and then to compare these results with the previous diagnostic samples. The cell line samples will not be used for patient diagnosis.

There are limited data concerning the use of biosimilars of filgrastim in autologous stem cell transplantation (ASCT). This study aimed to evaluate G-CSF efficiency and safety (based on haemograms, transfusion needs and complications) of two biosimilars (Zarzio and Ratiograstim®) compared to those of Neupogen® for our patients who underwent ASCT.

RATIONALE: Studying samples of tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is looking at genes in tissue samples from patients with B-cell non-Hodgkin lymphoma.

RATIONALE: Studying samples of tissue from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer. It may also help doctors predict how well patients will respond to treatment. PURPOSE: This research study is studying biomarkers in patients with diffuse large B-cell lymphoma treated with combination chemotherapy with or without rituximab.

In this study, radiation therapy plans will be made for 20 consecutive patients with mediastinal Hodgkin lymphoma or aggressive non-Hodgkin lymphoma. One plan is done using a breathing adapted pre-chemo PET-CT scan fused with a post-chemo planning CT scan and another plan is done using the standard procedure with pre-chemo PET-CT fused with post-chemo planning CT scan. Dose levels to the lymphoma and to the organs of risk will be compared in each patient. The best radiation therapy plan will be used to treat the patient.

Background: The malignant lymphomas, Hodgkin´s disease (HD) and non-Hodgkin´s lymphoma (NHL), comprise approximately 5-6% of all malignancies in adults and account for 10% of childhood cancers. Once the diagnosis has been established histologically, extent of disease (staging) and response to therapy will be assessed by means of a computed tomography (CT) scan of the body. The staging at presentation is important for determining prognosis and choice of treatment. Unfortunately, CT is accompanied by a significant amount of radiation exposure which may induce second cancers. This is especially important in childhood, because rapidly dividing cells are more sensitive to radiation induced effects and children will have more years ahead in which cancerous changes might occur. New magnetic resonance imaging (MRI) techniques offer an alternative way for staging and follow-up of cancers, including the malignant lymphomas. Whole-body MRI (WB-MRI) is a radiation-free method which allows imaging of the body with excellent soft tissue contrast in a single examination. Purpose: The aim of this study is to examine if WB-MRI can replace CT in staging of patients with a malignant lymphoma. Design: This will be a multicenter, prospective, diagnostic cohort study (timeschedule: 36 months). 135 eligible patients will undergo WB-MRI on top of the protocolar imaging routinely done. Study population: Patients aged 8 years and older with a histological diagnosis of HD or NHL. Statistical analysis: The challenge of this study will be to show non-inferiority of WB-MRI compared to CT in staging malignant lymphoma. Testing of this hypothesis will be one-sided and performed using recently proposed techniques by Lui et al. Radiation-related risk assessment: A risk model will be used, based on the BEIR VII report, for modelling the late-term mortality from radiation induced tumors after exposure to ionizing radiation. Economic evaluation: Actual costs (from a societal perspective) will be determined for the two diagnostic tests. In case of clinical equivalence and similar costs or cost savings associated with MRI the latter can be considered dominant, obviating further economic evaluation. Otherwise, through modelling of expected long term health impact and associated outcomes such as quality of life and costs the incremental cost effectiveness will be evaluated.

RATIONALE: Questionnaires that measure quality of life may improve the ability to plan treatment for children with cancer. PURPOSE: This randomized clinical trial is studying the quality of life in children treated for cancer.

Non-Hodgkin's lymphoma (NHL) is the third most rapidly increasing cancer in the United States. HIV-related NHL is responsible for some of the increase since the early 1980s. However, it cannot explain the steady increase in the incidence rates in earlier years, nor the entire increase shown recently. A possible role of environmental exposures is receiving attention. One possibility is that exposure to organochlorines (OCs) may be related to the occurrence of NHL. NCI is currently designing a large population-based case-control study to investigate this hypothesis further by analyzing OC levels in blood collected at the time of interview from cases of NHL and their matched controls. At the time of these interviews, cases in the main case-control study would most likely have already received chemotherapy. If chemotherapy changes the blood levels of OCs, this may lead to misclassification of exposure among cases and eventually to biased risk estimates. The purpose of this pilot study is to estimate the bias due to measuring the serum levels of OCs in cases during or after chemotherapy. Twenty newly diagnosed patients will be recruited for the study. From each patient, four consecutive blood samples, one prior to, two during, and one after chemotherapy, will be collected. Forty pairs of pre-existing cryopreserved serum samples (pre- and post-treatment) taken from the NHL patients who participated in an earlier NCI clinical study will also be included in this study. Samples will be assayed for OC levels. The results will be used to plan and to interpret another large case-control study (the main study).

Unicentric retrospective analysis of a cohort of 602 young adult and adolescent patients, aged 15 to 30 years, with haematological malignancies, and managed between 2000 and 2016

Chemokine receptor CXCR4 was expressed in MM and lymphoma cells and CXCR4-targeting molecular imaging- 68Ga-Pentixafor PET/CT could be a promising technique to evaluate the extent of MM and lymphoma with higher accuracy. This prospective study is going to investigate whether metabolic characterization by 68Ga-Pentixafor PET/CT may be superior for diagnosis, risk stratification, and prognostic evaluation of MM and lymphoma.
