A 66-year-old woman was admitted with high fever, systemic lymphadenopathy, hepatosplenomegaly and pancytopenia. Bone marrow aspiration showed infiltration of atypical lymphoid cells and hemophagocytic histiocytes. The findings of lymph node biopsy were compatible with angioimmunoblastic T-cell lymphoma (AILD). A diagnosis of lymphoma-associated hemophagocytic syndrome (LAHS) was made. Treatment with the THP-COP regimen achieved clinical remission except for mild splenomegaly, but relapse of LAHS was confirmed two years after diagnosis. The patient's condition deteriorated rapidly, and she died of multi-organ failure one month later. Autopsy revealed extended, diffuse infiltration of lymphoma cells in almost all organs. Numerous macrophages showing phagocytosis of erythrocytes and nucleated cells were found in the adrenal glands, lungs, bone marrow, spleen and liver. Epstein-Barr virus genomes were not detected by in situ hybridization, but cytotoxic molecules were immunostained with TIA-1 and granzyme B in the lymphoma cells. Elevated serum levels of sIL-2R, IFN-gamma, IL-6 and M-CSF were found at the onset and relapse of lymphoma. Overproduction of these cytokines was considered to have contributed to the pathogenesis of HPS.

A 71-year-old woman was admitted in December 2002 because of lymphadenopathy, hepatosplenomegaly and pleural effusion. She had severe anemia with hemoglobin 5.9 g/dl and a reticulocyte count of 1% per hundred. Direct/indirect Coombs tests and anti-double stranded DNA antibody were positive, her serum CH50 level was reduced and an increase in serum LDH isoenzyme 3 was observed. Bone marrow aspiration showed an almost total absence of erythroblasts and no pathological cell proliferation. The diagnosis of angioimmunoblastic T-cell lymphoma (AILT) was made based on the lymph node histological findings. Proliferation of arborizing small vessels with hyperplastic endothelium and infiltration of atypical T-lymphocytes were observed. After combination chemotherapy (THP-COP), remission was achieved in both the pure red cell aplasia (PRCA) and AILT. Remission was also accompanied by normalization of the Coombs tests, suggesting that autoimmune mechanisms in AILT may contribute to the development of PRCA.

We analysed the long-term outcome of the L86 protocol using L-asparaginase (L-asp), vincristine (VCR) and prednisolone (PSL), collectively known as LVP or L97 protocol using LVP along with pirarubicin hydrochloride (THP-ADR) for 97 patients with acute lymphoblastic leukemia (ALL) diagnosed between 1986 and 2002. No significant differences were seen in the two protocols regarding the complete remission (CR) rate or survival. Seventy-five of the 97 patients (77%) achieved a CR. The overall survival (OS) and disease-free survival (DFS) rates were 32.1% and 30.4% at 10 years, respectively. By univariate analysis, we identified seven adverse factors for DFS which included the L2 subtype by French-American-British classification, hepatosplenomegaly, a white blood cell count of more than 30 x 10(9)/L, a blast cell count of more than 10 x 10(9)/L in the peripheral blood, hemoglobin concentration greater than 10 g/dL, a serum lactate dehydrogenase value greater than twice the upper limit of normal and the presence of the Philadelphia chromosome (Ph). According to multivariate analysis, only the presence of Ph was a significant unfavourable factor for DFS and OS. In the 30 patients under 35 years of age without Ph, the OS in the 20 patients treated with L86 and in the 10 patients treated with L97 were 48 and 86%, respectively (P = 0.011). These results indicate that intensified chemotherapy, such as the L97 protocol that includes an anthracycline, might be beneficial for younger patients who are Ph-negative.
