Molecular Classification of Primary Mediastinal Large B Cell Lymphoma Using Formalin-Fixed, Paraffin-Embedded Tissue Specimens

Primary mediastinal B-cell lymphoma (PMBCL) is an aggressive type of non-Hodgkin lymphoma that mostly occurs in people between the ages of 30-40. It accounts for 5-7% of all aggressive lymphomas. The diagnosis of PMBCL is challenging as the histological features of PMBCL overlap with diffuse large B-cell lymphoma (DLBCL), another most common type of non-Hodgkin lymphoma. Available evidence suggests that PMBCL responds much more favorably to the DA-EPOCH-R chemotherapy regimen than to the standard R-CHOP regimen used to treat DLBCL. The diagnostic uncertainty of PMBCL can result in delayed and/or inappropriate treatment, serious harm, and even death of the patient, so there is a need to more precisely diagnose PMBCL.   Researchers at the National Cancer Institute (NCI) have developed a gene expression-based assay comprising a set of 58 nucleic acid probes that measure the abundance of selected mRNA species using the Nanostring platform. This assay can be used successfully to better distinguish PMBCL from DLBCL and applied to further classify DLBCL into well-established cell-of-origin subtypes. This test can be applied by clinicians to support the pathological diagnosis of PMBCL, and therefore identify a group of patients whose tumors are characterized by a distinct underlying biology.   The NCI seeks licensees and/or co-development partners to develop this technology toward commercialization.IC: NCINIH Ref.

We report here a case of pediatric ALCL complicated with acute liver failure due to the aggravation of pre-existing biliary hepatopathy by lymphoma-associated hemophagocytic lymphohistiocytosis (HLH). Although the initial treatment response against ALCL was very good, poor and irreversible liver function due to biliary cirrhosis worsening by lymphoma-associated HLH prevented the patient from receiving further consolidation chemotherapies. To make matters worse, his condition was accompanied with intrahepatic fungal pseudoaneurysm and invasive fungal infection. Thus, we decided to perform an urgent living-donor liver transp...

Mantle cell lymphoma is a rare, aggressive, and largely incurable form of non-Hodgkin lymphoma. There are a number of well-characterized prognostic features but nothing that can help guide therapy. Treatment with chemotherapy is generally effective in the short term, but relapse is inevitable and subsequent treatment is challenging. The use of Bruton tyrosine kinase inhibitors, however, has transformed practice. These agents are highly active in relapsed disease and are very well-tolerated drugs. Chemotherapy-free combinations using Bruton tyrosine kinase inhibitors look very exciting and will likely evolve to be part of f...

Conclusions: IC fungal abscesses in children can cause significant morbidity and mortality in children with hematolymphoid cancers. Evaluation of cerebrospinal fluid galactomannan may help in early diagnosis and therapy. Prolonged antifungal therapy steered by TDM can help achieve resolution in some cases.

Abstract Lymphoma is a group of malignant neoplasms of lymphocytes with more than 90 subtypes. It is traditionally classified broadly as non-Hodgkin or Hodgkin lymphoma. Approximately 82,000 new U.S. patients are diagnosed with lymphoma annually. Any tobacco use and obesity are major modifiable risk factors, with genetic, infectious, and inflammatory etiologies also contributing. Lymphoma typically presents as painless adenopathy, with systemic symptoms of fever, unexplained weight loss, and night sweats occurring in more advanced stages of the disease. An open lymph node biopsy is preferred for diagnosis. The Lug...

Lymphomas represent the third most common type of cancer in young people, classified into non-Hodgkin (NHL) or Hodgkin lymphoma. NHL arises when B or T cells, which are involved in the protection, become malignant, growing uncontrollably, "contaminating" the lymphatic system. Characterized by a high degree of malignancy with pathology and immunology of different characteristics. Radiotherapy or chemotherapy are treatments performed for this disease, which may lead to oral manifestations because of its cytotoxicity.

A promising and expensive type of immunotherapy, called CAR T-cell therapy, is now covered by Medicare. This news may affect mesothelioma patients in the future. Chimeric antigen receptor T-cell, or CAR T-cell, therapy involves the laboratory reprogramming of a patient’s T cells, which are a type of white blood cell responsible for protecting the body against infection and disease. The T cells are genetically modified to better recognize and attack cancer. The U.S. Food and Drug Administration has approved the immunotherapy procedure for non-Hodgkin lymphoma and B-cell precursor acute lymphoblastic leukemia. It is...
