Oncologic immunotherapies use a patient's immune response to eliminate tumor cells by modulation of immune checkpoints, including programmed cell death 1 (PD-1) and cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) proteins. Immune-mediated sequelae, including interstitial nephritis, have been reported; however, glomerular disease appears rare. We describe 2 cases of nephrotic syndrome in patients treated with these agents. Patient 1 received the anti-PD-1 antibody pembrolizumab for Hodgkin lymphoma. Following his second dose, he developed nephrotic syndrome and acute kidney injury...

We used CRISPR/Cas9-mediated genomic modification to investigate B-cell receptor (BCR) signaling in cell lines of diffuse large B-cell lymphoma (DLBCL). Three manipulations that altered BCR genes without affecting surface BCR levels showed that BCR signaling differs between the germinal center B-cell (GCB) subtype, which is insensitive to BTK inhibition by ibrutinib, and the activated B-cell (ABC) subtype. Replacing antigen-binding BCR regions had no effect on BCR signaling in GCB-DLBCL lines, reflecting this subtype's exclusive use of tonic BCR signaling...

Current understanding of the mutation spectrum of relapsed/refractory (RR) tumors is limited. We performed whole exome sequencing (WES) on 47 diffuse large B cell lymphoma (DLBCL) tumors that persisted after R-CHOP treatment, 8 matched to primary biopsies. We compared genomic alterations from the RR cohort against two treatment-naïve DLBCL cohorts (n=112). While the overall number and types of mutations did not differ significantly, we identified frequency changes in DLBCL driver genes. The overall frequency of MYD88 mutant samples increased (12% to 19%), but we noted a decrease in p...

We present the largest series of diffuse large B-cell lymphoma (DLBCL) in patients younger than 18 years analysed to date by gene expression profiling using Nanostring technology to identify molecular subtypes and fluorescent in situ hybridization for translocations of MYC. We show that the activated B cell-like subtype of DLBCL is exceedingly rare in children and - in contrast to adults- not associated with outcome. Furthermore, we review the current literature and demonstrate that MYC translocations are not more frequent in paediatric compared to adult DLBCL...

The optimal therapeutic approach for young diffuse large B-cell lymphoma (DLBCL) patients with high-intermediate and high-risk age-adjusted international prognostic index (aaIPI) remains unknown. Hereby we report a 10-year single-centre study of 63 consecutively treated patients. To optimize outcome, two approaches were carried out: Cohort 1 patients received four cycles R-CHOP-21 (rituximab, cyclophosphamide, daunorubicin, vincristine, prednisolone over 21 days) followed by first-line high-dose chemotherapy with autologous stem-cell support (HDCT-ASCT), resulting in 2-year progression-free (PFS) and overall survival (OS) of 60·6% and 67·9%...

Diffuse large B-cell lymphoma (DLBCL) is the most frequent type of non-Hodgkin lymphoma. Despite a favorable therapeutic response to first-line chemo-immunotherapy, still 30-40% of patients is refractory, or relapse after this treatment. Thus, alternative strategies must be sought. Previous studies have indicated that cyclin-dependent kinase 5 (CDK5), a serine/threonine protein kinase, is involved in tumor development and progression, and it may represent a potential therapeutic target. However, its role in modulating DLBCL growth and progression remains largely unexplored...

This study was performed to analyze the treatment outcome for diffuse large B-cell lymphoma (DLBCL) involving the head and neck and to evaluate the role of radiotherapy in the rituximab era. Fifty-six patients diagnosed with DLBCL involving the head and neck were assessed. All patients were treated with 6 cycles of rituximab, cyclophosphamide, adriamycin, vincristine, and prednisolone (R-CHOP). After chemotherapy, radiation was delivered to the head and neck area in a median dose of 36 Gy. Radiation was delivered using 3-dimensional radiotherapy (n  =  25) or intensity-modulated radiotherapy (n  =  31)...

INTRODUCTION: MYC overexpression is a common feature of diffuse large B-cell lymphoma (DLBCL) and is associated with poor prognosis in patients with this neoplasm. The underlying mechanisms of MYC dysregulation, however, have not been fully understood. MATERIALS AND METHODS: We immunohistochemically evaluated the correlation between BCR-PI3K pathway activity and MYC protein level in 108 cases of de novo DLBCL, twenty five of which featured loss of B-cell receptor (BCR-negative), and investigated the effects of BCR-PI3K signaling on MYC protein level and phosphorylation in DLBCL cell lines...

Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (DLBCL) is a haematologic malignancy with poor prognosis when treated with chemotherapy. We evaluated response and survival benefits of chemoimmunotherapy in EBV-positive DLBCL patients. A total of 117 DLBCL patients were included in our retrospective analysis; 33 were EBV-positive (17 treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone [R-CHOP] and 16 with CHOP), and 84 were EBV-negative (all treated with R-CHOP)...

A case of a 16-year-old female with polyarticular juvenile idiopathic arthritis (JIA) since the age of 4 years is reported here. This patient also suffered from multiple congenital anomalies. On long-term treatment with oral methotrexate (MTX) and etanercept, multiple subcutaneous nodules were detected, which were accompanied by increased lactate dehydrogenase and uric acid levels. A biopsy of the largest nodule revealed Epstein-Barr (EB) virus-positive diffuse large B-cell lymphoma (DLBCL). The patient was classified as clinical stage IIIA due to a mediastinal lesion...

We herein report a case in which thoracoscopic thymectomy with partial resection of the brachiocephalic vein was performed using a subxiphoid approach. We suggest the usefulness of the subxiphoid approach in thymectomy. We could extend the indications of thoracoscopic thymectomy for invasive tumors. Thoracoscopic thymectomy with the combined resection of part of the brachiocephalic vein was possible. The pathological diagnosis of the tumor was diffuse large cell B-cell lymphoma. Since the postoperative complications were minimal, postoperative adjuvant chemotherapy could be initiated without delay...

BACKGROUND: MicroRNAs (miRs) are involved in tumor progression by regulating tumor cells and tumor microenvironment. MiR21 is overexpressed in diffuse large B-cell lymphoma (DLBCL) and its biological impact on tumor microenvironment remains unclear. METHODS: MiR21 was assessed by quantitative RT-PCR in patients with newly diagnosed DLBCL. The mechanism of action of miR21 on lymphoma progression and tumor angiogenesis was examined in vitro in B-lymphoma cell lines and in vivo in a murine xenograft model...

BACKGROUND: Epstein-Barr Virus (EBV) is associated with hematopoietic malignancies, such as Burkitt's lymphoma, post-transplantation lymphoproliferative disorder, and diffuse large B-cell lymphoma. The current approach for EBV-associated lymphoma involves chemotherapy to eradicate cancer cells, however, normal cells may be injured and organ dysfunction may occur with currently employed regimens. This research is focused on employing arsenic trioxide (ATO) as EBV-specific cancer therapy takes advantage of the fact the EBV resides within the malignant cells...

Abdominal CSF pseudocysts are an uncommon complication of ventriculo-peritoneal shunting. We report the case of a 35 year old man with a myelomenigocele, associated Chiari 2 malformation, and VP shunt developing a Diffuse Large B-Cell Lymphoma within the lining of an abdominal CSF pseuodcyst. This diagnosis should be considered in those with recurrent pseudocysts, or those associated with a swinging pyrexia and high C-Reactive protein, in the absence of infection.
