Report on the First International Workshop on interim-PET scan in lymphoma

Abstract: An international workshop, under the auspices of Group d'Etude des Lymphomes de l'Adulte (GELA) took place in Deauville, France, in April 3-4, 2009. The European experts with a published or personal experience on interim-PET in lymphoma were invited to the meeting. The aim of the workshop was twofold: (1) to reach a consensus on simple, reproducible criteria for interim-PET interpretation in Hodgkin lymphoma and diffuse large B-cell lymphoma (DLBCL), and (2) to launch two or more international validation studies, in an attempt to validate these rules. We concisely report here the minutes of the meeting and the conclusions/statements that have been reached.

CD19 Antigen in Leukemia and Lymphoma Diagnosis and Immunotherapy

Abstract: The CD19 antigen plays an important role in clinical oncology. In normal cells, it is the most ubiquitously expressed protein in the B lymphocyte lineage. CD19 expression is induced at the point of B lineage commitment during the differentiation of the hematopoietic stem cell, and its expression continues through preB and mature B cell differentiation until it is finally down-regulated during terminal differentiation into plasma cells. CD19 expression is maintained in B-lineage cells that have undergone neoplastic transformation, and therefore CD19 is useful in diagnosis of leukemias and lymphomas using monoclonal antibodies (mAbs) and flow cytometry. Interestingly, CD19 is also expressed in a subset of acute myelogenous leukemias (AMLs) indicating the close relationship between the lymphoid and myeloid lineages. Because B lineage leukemias and lymphomas rarely lose CD19 expression, and because it is not expressed in the pluripotent stem cell, it has become the target for a variety of immunotherapeutic agents, including immunotoxins. Treatment of non-Hodgkin's lymphoma (NHL) and acute lymphocytic leukemia (ALL) with anti-CD19 mAbs coupled to biological toxins has proven to be effective in vitro and in animal models, and has shown some promising results in Phase I clinical trials. Recently, the analysis of anti-CD19 effects on lymphoma cell growth has highlighted a novel mechanism of immunotherapy. Engagement of cell surface receptors like CD19 by mAbs can have anti-tumor effects by the activation of signal transduction pathways which control cell cycle progression and programmed cell death (apoptosis).

Hyperleukocytic leukemias and leukostasis: a review of pathophysiology, clinical presentation and management.

Abstract: Acute hyperleukocytic leukemias (AHL) are associated with a very high early mortality rate mostly due to respiratory failure or intracranial bleeding. The pathophysiological process leading to thes...

Triptolide, a novel immunosuppressive and anti-inflammatory agent purified from a Chinese herb Tripterygium wilfordii Hook F.

Abstract: Triptolide is a diterpenoid triepoxide purified from a Chinese herb Tripterygium Wilfordii Hook F (TWHF). TWHF has been used in traditional Chinese medicine for more than two thousand years. However, its potential value was recognized by the western medicine only after investigators observed the effectiveness of TWHF in the treatment of leprosy and rheumatoid arthritis. Triptolide has been identified as the major component responsible for the immunosuppressive and anti-inflammatory effects of TWHF. Triptolide inhibits both Ca(2+)-dependent and Ca(2+)-independent pathways and affects T cell activation through inhibition of interleukin-2 transcription at a site different from the target of cyclosporin A. Triptolide also has inhibitory effects on a variety of proinflammatory cytokines and mediators and on the expression of adhesion molecules by endothelial cells. Triptolide is effective for the treatment of a variety of autoimmune diseases and in prevention of allograft rejection and graft-versus-host disease in both animals and humans. Moreover, triptolide possesses antitumor and male anti-fertility effect. However, the toxicities of triptolide may be associated with renal, cardiac, hematopoietic and reproductive systems. Currently available data suggest that triptolide is a promising immunosuppressive and anti-inflammatory agent and should be explored further in autoimmune diseases and transplantation.

Management of adverse events associated with idelalisib treatment: expert panel opinion

Abstract: Idelalisib is a first-in-class selective, oral, phosphatidylinositol 3-kinase delta (PI3Kδ) inhibitor approved for the treatment of several types of blood cancer. Idelalisib has demonstrated significant efficacy and a tolerable safety profile in clinical trials. However, the US prescribing information contains a black box warning for fatal and/or severe diarrhea or colitis, hepatotoxicity, pneumonitis and intestinal perforation. An expert panel was convened to review the pathology of these treatment-emergent adverse events (TEAEs) to propose key management tools for patients receiving idelalisib therapy. This article provides an overview of idelalisib TEAEs reported in clinical trials, and a summary of the panel's recommendations for identification and management of idelalisib treatment-emergent diarrhea or colitis as well as a discussion of transaminitis and pneumonitis. For idelalisib-related diarrhea or colitis (including unresolved grade 2 and grade ≥ 3), after exclusion of infectious causes, the panel recommends individualized treatment with budesonide or oral or intravenous steroid therapy.
