B-Receptor Signaling in Cardiomyopathy
CarcinomasAmyloidosis37 moreWe hope to determine the importance of different genes (including B receptors) in anthracycline-induced cardiomyopathy. This has important benefits to patients exposed to anthracyclines, as this could help determine whether certain individuals have increased susceptibility to cardiac injury.
Whole-body Magnetic Resonance Imaging (MRI) for Staging Malignant Lymphomas
Malignant LymphomaHodgkin's Disease1 moreBackground: 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.
A Pilot Study of Non-Hodgkin's Lymphoma: Chemotherapy and Blood Levels of Organochlorines
HIV InfectionsLymphoma3 moreNon-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).

Subclinical Cardio-toxicities Evaluation With Strain Rate Echocardiography After Chemotherapy and/or...
LymphomaNon-Hodgkin3 moreTreatments-related cardiotoxicity is a critical issue in long term lymphoma survivors, particularly at young age, and its early identification is important to prevent clinically relevant cardiac events. Complete echocardiographic assessment including 2-dimension global longitudinal strain (2D-GLS), seems to be an effective tools in detecting preclinical systolic changes to the cardiac function even when the ejection fraction is preserved. The aim of Cardiocare study is to investigate early detection of subclinical chemo and radiation-induced changes in left ventricular function using 2D-GLS.
Health and Psychosocial Outcomes in Long-Term Lymphoma Survivors
LymphomaNon-Hodgkins1 moreThe aims and objectives of this research are to identify chronic health conditions, psychological disease, quality of life issues, and patient preferences for survivorship care in patients who have survived aggressive lymphoma. Subjects will be asked to participate in an oral interview with the primary investigator, either in-person or over the telephone. It is estimated that the survey will take about an hour.

Assessing Response to Treatment in Non-Hodgkin's Lymphoma Patients Using 64Cu-DOTA-Rituximab PET/CT...
Non-Hodgkin's LymphomaRituximab is an antibody targeted against the CD20 antigen found primarily on B-cells. Therefore, an imaging agent targeting CD20 expression may provide a more accurate evaluation of extent of disease and response to therapy than the current standard of care, F-18 FDG PET/CT. The main purpose of the study is to investigate a new PET/CT imaging probe for detection and follow up of lymphoma. Following are the 3 aims of the study: a) Phase I testing in lymphoma patients of Cu-64 labelled Rituxan for defining normal tracer biodistribution, stability, pharmacokinetics and radiation dosimetry; b) comparison of Cu-64 Rituxan and F-18 FDG PET/CT in lymphoma patients; c) evaluation of changes in uptake of Cu-64 Rituxan in response to rituximab-based treatment in CD20-positive B-cell NHL
