Pan-phosphatidylinositol 3-kinase inhibition with buparlisib in patients with relapsed or refractory non-Hodgkin lymphoma.

Activation of the phosphatidylinositol 3-kinase/mechanistic target of rapamycin pathway plays a role in the pathogenesis of non-Hodgkin lymphoma. This multicenter, open-label phase 2 study evaluated buparlisib (BKM120), a pan-class I phosphatidylinositol 3-kinase inhibitor, in patients with relapsed or refractory non-Hodgkin lymphoma. Three separate cohorts of patients (with diffuse large B-cell lymphoma, mantle cell lymphoma, or follicular lymphoma) received buparlisib 100 mg once daily until progression, intolerance, or withdrawal of consent.

Phase I/II study of bortezomib-BEAM and autologous hematopoietic stem cell transplantation for relapsed indolent non-Hodgkin lymphoma, transformed, or mantle cell lymphoma.

A phase I/II trial was designed to evaluate the safety and efficacy of adding bortezomib to standard BEAM (BCNU, etoposide, cytarabine, melphalan) and autologous hematopoietic stem cell transplantation (ASCT). Eligible patients had relapsed/refractory indolent or transformed non-Hodgkin lymphoma or mantle cell lymphoma (MCL) that was relapsed/refractory or in first partial (PR) or complete remission (CR). Patients received bortezomib on days -11, -8, -5, and -2 before ASCT.

Cardiac magnetic resonance imaging for the assessment of the myocardium after doxorubicin-based chemotherapy.

Objectives: Doxorubicin is associated with a cumulative dose-dependent nonischemic cardiomyopathy. Cardiac magnetic resonance imaging (cMRI) is able to examine both structural and functional components of the myocardium. Our aim was to assess the myocardial changes in non-Hodgkin lymphoma patients undergoing doxorubicin-based chemotherapy using cMRI.

The utility of lactate dehydrogenase in the follow up of patients with diffuse large B-cell lymphoma.

Background: Serum lactate dehydrogenase is a non-specific marker for lymphoma whose prognostic significance is well established for both indolent and aggressive lymphomas at the time of diagnosis. The performance characteristics of this enzyme in predicting relapse in patients with diffuse large B-cell lymphoma has not been well studied.

Methods: This study compared serum lactate dehydrogenase levels in 27 patients with diffuse large B-cell lymphoma who relapsed after sustaining a complete response versus 87 patients who did not relapse.

B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and burkitt lymphoma: study of 39 cases.

B-cell lymphoma, unclassifiable (B-UCL), with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma, is a poorly characterized entity. Therefore, we investigated cases of B-UCL treated by the Nebraska Lymphoma Study Group (NLSG). We searched the NLSG registry for years 1985-2010 for cases of B-UCL.

Expression of PKC-beta or cyclin D2 predicts for inferior survival in diffuse large B-cell lymphoma.

We sought to determine whether identification of poor-risk subgroups of diffuse large B-cell lymphoma (DLBCL) using immunohistochemical stains would have practical utility with regard to prognosis and therapeutic decisions. Tissue microarray blocks were created using replicate samples of formalin-fixed, paraffin-embedded tissue from 200 cases of de novo DLBCL. The sections were stained with antibodies to proteins that are expressed by activated or proliferating B cells including MUM1, FOXP1, bcl-2, survivin, protein kinase C-beta (PKC-beta), cyclin D2, cyclin D3, and Ki-67.
