Abstract:
Abstract Large cohort studies, such as the Women’s Health Initiative, have traditionally grouped hematopoietic neoplasms (HPN) into disease categories including multiple myeloma (MM), non-Hodgkin lymphoma (NHL), Hodgkin lymphoma (HL), and leukemia, however this may not allow for optimal distinction of biologically relevant associations. The 2001 World Health Organization (WHO) classification of HPN represents the current gold standard classification scheme, and has been incorporated into the International Classification of Disease for Oncology, Third Edition (ICD-O-3).

Abstract CD52 is a GPI-linked glycoprotein expressed by B cells, T cells, monocytes and macrophages.

The utility of alemtuzumab in the treatment of other lymphoid and non-lymphoid malignancies has been recently explored; however, a comprehensive survey of CD52 expression among the various classes of hematopoietic neoplasms has not been completed.

Abstract:
Although the diagnosis of canine leukemia and lymphoma in advanced stages is usually uncomplicated, some presentations of the disease can be a diagnostic challenge. In certain situations, lymphoma and leukemia can be difficult to distinguish from a benign reactive proliferation of lymphocytes. Because clonality is the hallmark of malignancy, we have developed an assay that uses the polymerase chain reaction to amplify the variable regions of immunoglobulin genes and T-cell receptor genes to detect the presence of a clonal lymphocyte population. The assay detected clonally rearranged antigen re

Abstract CD11b is well known as an integrin, Mac-1, is often complexed with CD18, and is found on monocytes, granulocytes, and natural killer cells. It also serves as a receptor for iC3b. However, its occurrence in B cell chronic lymphoproliferative disorders is not generally recognized and has not been fully evaluated. To address this issue, a series of B cell leukemias and lymphomas referred for primary diagnosis was evaluated for the presence of CD11b. The purpose was to determine the frequency of its expression on these tumors and to evaluate its diagnostic value. Consecutive cases referre

Abstract On the path to successful immunotherapy of hematopoietic tumors, γδ T cells offer great promise because of their human leukocyte antigen (HLA)–unrestricted targeting of a wide variety of leukemias/lymphomas. However, the molecular mechanisms underlying lymphoma recognition by γδ T cells remain unclear. Here we show that the expression levels of UL16-binding protein 1 (ULBP1) determine lymphoma susceptibility to γδ T cell–mediated cytolysis. Consistent with this, blockade of NKG2D, the receptor for ULBP1 expressed on all Vγ9+ T cells, significantly inhibits lymphoma cell killing. Speci
