Active clinical trials for "Lymphoma"

Background: - Lymphoma rates in Asia have been lower than in the West, but rates have been rising in recent years. Most studies of lymphoma patients have been conducted in the West. Less information is available about the factors that might contribute to the rise of lymphoma in Asia. Researchers want to collect medical and personal histories and samples from people who have recently been diagnosed with lymphoma. This information will help them study possible reasons for this increase. Objectives: - To collect samples and histories as part of an introductory study of lymphoma in Asia. Eligibility: People between 18 and 79 years of age who have entered study hospitals in Hong Kong, Taiwan, and mainland China for treatment for any type of lymphoma. Healthy volunteers between 18 and 79 who have never had lymphoma. Design: Participants will be screened with a physical exam and medical history. They will provide blood samples and cheek cell samples for testing. Participants will complete a questionnaire about their personal health history. They will answer questions about exposures to chemicals like pesticides. They will also be asked about family medical history and work and residential history. Finally they will answer questions about lifestyle factors like diet and exercise. They will give permission for the researchers to see their medical records. Researchers will also have access to any tumor samples collected as part of treatment.

The investigators perform a retrospective microarray gene expression profiling study of FFPE from a cohort of DLBCL patients with whole genome cDNA mediated Annealing Selection and Ligation (WG-DASL) assay. The investigators also study the pattern of microRNA from patients with diffuse large B-cell lymphoma. The results of gene expression profiles and microRNA is correlated with clinical outcomes of diffuse large B-cell lymphoma.

Diffuse Large B-cell Lymphoma (DLBCL) is the most frequent high grade lymphoma in adults. Although immunotherapy has improved its prognosis, DLBCL is a heterogeneous disease with patients exhibiting a wide range of outcomes with a 5-year overall survival ranging between 55 to 94% depending of the International Prognostic Index factor. Diagnostic and prognostic biomarkers are mandatory to optimize treatment. Transcriptomics has been used to detect such new biomarkers using microarrays analyses applied to RNA collected from total tumor tissues or cell extracts. Molecular prognostic factors have been thoroughly studied in DLBCL tumor tissues. However, it is a big challenge to obtain transcriptomic-qualified tumor samples in a multicentric and prospective clinical trial. Coordinating nvestigator hypothesized that blood may be a deep source of native and secreted analytes and therefore carries transcriptomic signatures related to DLBCL and its prognosis. This project is organized in the extension of the GOELAMS-075 clinical trial which concerns aggressive DLBCL.

Prospective, longitudinal, multinational, observational study that will collect data on how patients with peripheral T-cell lymphoma (PTCL) are treated in academic and community practices.

The purpose of this study is to determine whether whether surgical resection followed by chemotherapy is superior to systemic chemotherapy alone in terms of treatment outcome and quality of life (QOL) in patients with primary intestinal lymphoma.

Newly diagnosed DLCL patients will have baselne FDG-PET as part of initial staging (PET-1). Patients will then undergo 2 cycles of chemotherapy with R/CHOP. 14 to 21 days following cycle 2 of R/CHOP, patients will undergo repeat FDG-PET scan (PET-2). They will then complete therapy as planned. Following completion of therapy, standard response assessment will be performed, including CT scans of the chest, abdomen and pelvis and FDG-PET scan (PET-3).

The purpose of this study is to compare different estimates of calculating creatinine clearance by mathematical formula and compare them to creatinine clearance based on a timed urine collection in patients who received high-dose methotrexate for the treatment of primary CNS lymphoma or CNS involvement of systemic lymphoma.

The majority of patients with Hodgkin Lymphoma (HL)are cured with radiation therapy and/or combination chemotherapy. However, patients who relapse after attaining a complete remission with chemotherapy and those with primary refractory disease have a poor outcome with conventional chemotherapy regimens. Treatment results with standard-dose second-line regimens produce low complete remission rates and minimal survival benefit. Single institution studies have shown better outcome after autologous stem cell transplant in this group of patients when compared to historical controls receiving conventional treatment. In this retrospective review, we aim to analyze outcome and determine independent prognostic factors which would correlate with the long-term outcome of patients with HL who received an autologous stem cell transplant in the past at the Royal Marsden Hospital Eligible patients (those on current-follow-up) identified from the transplant database will be eligible for the study. Accrual of eligible patients currently under follow-up will be performed in clinic at the time of next appointment. All patients accrued will give informed consent to participate in the study for retrospective case note review, after discussion with a study investigator and after receiving a study information sheet. The results of the analysis will be published in a peer-reviewed medical journal.

This study is to inquire by mailed survey regarding the cardiac and general health of patients previously treated for Hodgkin's and non-Hodgkin's lymphoma with radiation therapy/anthracycline chemotherapy.

This study is a retrospective analysis of an homogeneous population of patients with aggressive B-cell lymphoma and treated upfront with R-CHOP or R-CHOP like regimens to reassess the prognostic factors and hopefully to identify more accurate prognostic subgroups with a clinical and therapeutical relevance.
