Active clinical trials for "Lymphoma"

Gastric low-grade mucosa-associated lymphoid tissue lymphoma (MALToma) is associated with Helicobacter pylori (HP) infection, and around 70% of these tumors can be cured by HP eradication therapy (HPE). However, the role of antibiotics in the frontline treatment of extragastric MALToma remains unclear. In addition to anecdotal case reports showing histologic regression of extragastric MALTomas after antibiotics, our explorative study found that frontline HPE (clarithromycin, amoxicillin, and omeprazole) resulted in complete remission (CR) in this subgroup patients (2 salivary gland, 1 lung, 1 colon, and 4 ocular adnexal MALToma [OAML]). Interestingly, two patients with OAML who do not respond to Chlamydia psittaci (CP) eradication using doxycycline achieved CR after HPE. These findings suggest that bacterial infections, including HP, may be involved in the lymphomagenesis of these extragastric MALTomas. Our preliminary results also revealed that 5 (23.8%) of 21 HP-negative gastric MALToma patients achieved CR after HPE, indicating that antibiotics may also have ability to eradicate non-HP bacteria. Based on our preliminary findings and the indolent biologic behavior of MALToma, it is reasonable to use frontline HPE in the treatment of early-stage low-grade extragastric MALToma.

Outcome of Hodgkin lymphoma patients over than 60 years treated by chemotherapy and/or radiotherapy: retrospective analysis.

The autograft of patients with prognostically unfavourable B-cells lymphoma cells in first remission remains controversial, in particular since the association of Rituximab with chemotherapy. Even though many randomized and non-randomized studies have been conducted, their is still no standard procedure . Recently, the use of early TEP (positron emission topography) answer, after 2 in 3 cures of chemotherapy allowed to select the poor-responder patients who remain candidate to autograft in front-line. Nevertheless, in good-responder patients, the benefits of an intensification therapy ins term of long-lasting disease control remains discussion. This institutional retrospective study aims at comparing the outcome of early metabolic responder patients who received an intensification treatment to those who received a standard chemotherapy.

The designed study follows up on the previous one by the international T-cell project (Bellei et al,, 2012) and its purpose is to verify whether a prospective collection of data would permit access to more accurate information permitting a better definition of prognosis and investigation of more adequate treatment strategies for these neoplasms. The analysis of patients distributed in all five macro regions of the country and a comparison among them will provide a real picture of the disease in Brazil, limiting the bias probably found in the previous projects.

Children and adolescents with Hodgkin lymphoma currently undergo multiple investigations including a separate PET and MRI scans during their treatment. Investigators want to investigate if a combined PET-MRI scan could give the same information. Children who join our study will have an extra scan twice during their treatment

Marginal zone lymphoma is a rare of subtype of Non-Hodgkin Lymphoma. Because of its rarity, prospective clinical trial is difficult to conduct. Therefore we want to make prospective MZL patients' cohort for several observation study

Imaging techniques have considerably improved over the last decades and ocular adnexal lymphomas (OALs) nowadays can be detected. As major advances in immunophenotyping and molecular diagnostics in histology have been achieved offering an accurate diagnosis, the investigators would like to introduce that surgical biopsy of an orbital lymphoma becomes crucial for the possibility of a correct diagnosis and proper treatment. As radiotherapy accomplished great preciseness as well and OALs respond excellently to radiation, this therapy should be the treatment of choice in local defined lymphomas instead of blind treatment with steroids. Radiation results in great local control rates of 85% to 100% Trial with surgical intervention

Prospective, observational cohort study of peripheral T cell lymphoma. Purpose is to investigate the complication including febrile neutropenia in the era of pegylated G-CSF prophylaxis.

Prospective Data Collection of Newly Diagnosed Hodgkin's Disease and Non-Hodgkin's Lymphoma Cases

The purpose of this study is to determine whether a specific subtype of lymphoma responds optimally to treatment with rituximab and chemotherapy.
