  • [Title] Concomitant presentation of acute myeloid leukemia with T-cell large granular lymphocytic leukemia.
  • T-cell large granular lymphocyte leukemia (T-LGL) also known as T-cell chronic lymphocytic leukemia is rare and comprises a small minority of all small lymphocytic leukemias.
  • The concomitant presentation of T-LGL with acute myeloid leukemia (AML) has not been previously reported.
  • We present an elderly gentleman with concomitant T-LGL and AML (non-M3) diagnosed by a combination of morphologic evaluation, immunophenotyping by flow cytometry, and T-cell gene rearrangement studies.
  • The patient was managed with combination AML chemotherapy.
  • He remains alive and well seven months after initial diagnosis.

  • [Title] Pentostatin (Nipent) in T-cell malignancies. Leukemia Cooperative Group and the European Organization for Research and Treatment of Cancer.
  • Within this phase II trial of the European Organization for Research and Treatment of Cancer, we have investigated the safety and efficacy of pentostatin (Nipent; SuperGen, San Ramon, CA) in refractory lymphoid malignancies.
  • Pentostatin was administered at a dosage of 4 mg/m2 every week for the first 3 weeks, then every 14 days, followed by maintenance therapy of 4 mg/m2 monthly for a maximum of 6 months.
  • We have previously reported the results in T- and B-cell prolymphocytic leukemia, B-cell chronic lymphocytic leukemia, and hairy cell leukemia This report focuses on the outcome in T-cell malignancies: T-cell chronic lymphocytic leukemia, Sézary syndrome, mycosis fungoides, and T-zone lymphoma.
  • Of 92 patients with these diagnoses enrolled, 76 were evaluable for response and toxicity, ie, 25 of 28 with T-cell chronic lymphocytic leukemia, 21 of 26 with Sézary syndrome, 22 of 26 with mycosis fungoides, and eight of 12 with T-zone lymphoma.
  • All patients had progressive and advanced disease.
  • Sixteen patients (21%) died during the first 9 weeks of treatment: 12 of progressive disease, two of infectious complications thought to be unrelated to treatment, one of myocardial infarction, and one of renal failure related to administration of intravenous contrast.
  • Better results were achieved in patients with Sézary syndrome or mycosis fungoides (complete remission + partial remission = 33.4% and 22.7%, respectively) than in patients with T-cell chronic lymphocytic leukemia (8%) or T-zone lymphoma (25%).
  • We conclude that pentostatin is active in low-grade T-cell malignancies.
  • A higher dose might be necessary for some T-cell malignancies.

  • [Title] Evaluation of ZAP-70 expression by flow cytometry in chronic lymphocytic leukemia: A multicentric international harmonization process.
  • The clinical course of patients with chronic lymphocytic leukemia (CLL) is heterogeneous with some patients requiring early therapy whereas others will not be treated for years.
  • The evaluation of an individual CLL patient's prognosis remains a problematic issue.
  • Among the available techniques for ZAP-70 detection, flow cytometry is most preferable as it allows the simultaneous quantification of ZAP-70 protein expression levels in CLL cells and residual normal lymphocyte subsets.
  • However, several factors introduce variability in the results reported from different laboratories; these factors include the anti-ZAP-70 antibody clone and conjugate, the staining procedure, the gating strategy, and the method of reporting the results.
  • During this workshop, a technical consensus was reached on the methods for cell permeabilization and immunophenotyping procedures.
  • This procedure was applied to three stabilized blood samples, provided by the UK NEQAS group to all participating members of this study, in order to minimize variability caused by sample storage and shipment.
  • Various gating strategies were used and the ZAP-70 levels were expressed as percentage positive (POS) relative to isotype control or normal B-cells or normal T-cells; in addition the levels were reported as a ratio of expression in CLL cells relative to T-cells.
  • The CLL/T-cell ZAP-70 expression ratio showed a much lower interlaboratory variation than other reporting strategies and is recommended for multicenter studies.
  • We assessed the variation of ZAP-70 expression levels in fresh cells according to storage time, which demonstrated that ZAP-70 is labile but sufficiently stable to allow comparison using fresh samples distributed between labs in Europe.
  • These studies have demonstrated progress toward a consensus reporting procedure, and further work is underway to harmonize the preparation and analysis procedures.

  • [Title] A phase I study of immune gene therapy for patients with CLL using a membrane-stable, humanized CD154.
  • Ligation of CD40 on chronic lymphocytic leukemia (CLL) cells induces phenotypic and biochemical changes that facilitate CLL cell-T cell interactions and enhances the sensitivity of CLL cells to clearance by adaptive and innate immune-effector mechanisms.
  • CLL cells can be transduced to express CD40 ligand (CD154) using a replication-defective adenovirus vector, thereby cross-linking CD40 on transduced and non-transduced, bystander CLL cells.
  • In a previous study, patients received infusions of autologous CLL cells, transduced to express murine CD154 (mCD154), which induced anti-leukemic immune responses, but also anti-mCD154 antibodies.
  • In this study, we report a phase I study, in which patients were infused with 1 × 10(8), 3 × 10(8) or 1 × 10(9) autologous CLL cells transduced ex vivo to express ISF35, a humanized, membrane-stable CD154.
  • After infusion, circulating CLL cells had enhanced or de novo expression of CD95, DR5, p73 and Bid, which enhanced their susceptibility to death-receptor-mediated or drug-induced apoptosis, including CLL cells with deletions at 17p13.1 (del(17p)).
  • Two patients who had CLL with del(17p) had subsequent chemoimmunotherapy and responded well to treatment.
  • In summary, infusions of autologous, ISF35-transduced CLL cells were well tolerated, had biological and clinical activity, and might enhance the susceptibility of CLL cells with del(17p) to chemoimmunotherapy.

  • [Title] Treatment of chronic lymphocytic leukaemia in three dogs with melphalan and prednisolone.
  • Three adult dogs with chronic lymphocytic leukaemia (CLL) were successfully treated with melphalan and prednisolone.
  • Based on the immunophenotypic analysis of leukaemic cells, two dogs were diagnosed with B cell CLL and one dog was tentatively diagnosed as having T cell CLL.
  • One dog with B cell CLL had IgM monoclonal gammopathy.
  • The clinical signs and haematological abnormalities associated with CLL in the three dogs improved with the administration of cytoreductive melphalan (3 to 5 mg/m2/day) and prednisolone (4.3 to 30 mg/m2/day) for eight to 210 days.
  • Melphalan and prednisolone therapy may achieve remission with few side effects in dogs with CLL.

  • The morphology and distribution of neoplastic T-lymphocytes within the spleen, liver, peripheral blood, and bone marrow was most consistent with chronic T-lymphocytic leukemia.
  • Treatment with chlorambucil and prednisone effectively decreased the lymphocyte count, but was associated with thrombocytopenia, which resolved after chlorambucil treatment was temporarily discontinued.
  • Chemotherapy was resumed with a single dose of L-asparaginase, followed by a lower dosage of chlorambucil and continued prednisone.
  • Two years after initial diagnosis, the hyena developed a hemoabdomen and was euthanized.
  • Neoplastic T-lymphocytes were present in spleen, liver, visceral and peripheral lymph nodes, lungs, heart, kidney, adrenal glands, mesentery, intestines, pancreas, brain, and bone marrow.

  • [Title] Recombinant immunotoxins for the treatment of chemoresistant hematologic malignancies.
  • No agents of this class are approved yet for medical use, although a related molecule, denileukin diftitox, composed of interleukin-2 fused to truncated diphtheria toxin, is approved for relapsed/refractory cutaneous T-cell lymphoma.
  • Recombinant immunotoxins which have been tested in patients with chemotherapy-pretreated hematologic malignancies include LMB-2 (anti-CD25), BL22 (CAT-3888, anti-CD22) and HA22 (CAT-8015, anti-CD22), each containing an Fv fragment fused to truncated Pseudomonas exotoxin.
  • Major responses were observed with LMB-2 in adult T-cell leukemia, chronic lymphocytic leukemia (CLL), cutaneous T-cell lymphoma, Hodgkin's disease, and hairy cell leukemia (HCL).
  • HA22, an improved version of BL22 with higher affinity to CD22, is now undergoing phase I testing in HCL, CLL, non-Hodgkin's lymphoma, and pediatric acute lymphoblastic leukemia.
