We reported a rare case of non-Hodgkin's lymphoma of iliac bone which developed peripheral blood involvement associated with hypercalcemia. 42-year-old man was admitted to Fukui Medical School Hospital because of right iliac bone pain. An X-ray film of the pelvis disclosed the osteolytic change of right iliac bone. A CT scan of the pelvis showed soft tissue density tumors involved bilateral iliac bone. He had no superficial lymphadenopathy or organomegaly. Examination of peripheral blood and bone marrow did not show any abnormalities. Monoclonal immunoglobulin was not detected in serum. Examination of biopsied specimens from iliac bone tumor showed infiltration of round cells. Immunocytochemical analysis showed only MT-1 positive. He was treated with combination chemotherapy of vindesine, cyclophosphamide, prednisolone and pirarubicin followed by radiation therapy. But, there was no significant response. Following radiation therapy, he developed coma. Serum calcium was 9.8 mEq/l. The pathologic immature cells were found in peripheral blood. The bone marrow aspirates showed 63% pathologic cells. These cells expressed CD19, CD20, HLA-DR antigens. He was diagnosed as having leukemic non-Hodgkin's lymphoma, B-cell type, and was treated with combination chemotherapy. But he died of systemic fungal infection.

An immunohistochemical study of a rare initial manifestation of non-Hodgkin's lymphoma (NHL) in the ovaries is presented. There have been very few reports to date on immunohistochemical studies of lymphoma involving the ovaries. A 53-year-old woman suffering from lower abdominal pain and abnormal genital bleeding was diagnosed as having a tumor in her left ovary by ultrasonic echograms and CT scanning. The patient underwent a simple total hysterectomy and bilateral salpingo-oophorectomies. The tumor, measuring 14 x 10 x 10 cm, was located in the left ovary and extended to the major omentum, mesocolon and left ureter. The histology of the tumor was that of NHL showing diffuse proliferation of small cleaved cells. Immunohistochemical studies of the ovarian tumor showed that the tumor cells were of a B-cell lymphoma nature with LCA+, MB-1+, lambda+, keratin-, IgG-, IgM-, IgA-, kappa-, and MT-1-. Although the main lesion involved the ovary, the case could not be identified definitely as primary lymphoma of the ovary.

A rare case of primary orbital lymphoma with macroglobulinemia was reported. The patient was a 74-year-old male with bilateral orbital tumor. Exophthalmos and eye movement disturbance appeared in his left eye. Blood analysis showed a marked increase of serum immunoglobulin M. Immunochemical study showed 7,097 (mg/dl). The left tumor was partially removed and examined histopathologically and immunohistochemically. H.E. staining revealed the proliferation of lymphoplasmacytoid cells. Immunocytochemical staining showed these cells to be immunoglobulin G (-), immunoglobulin A (-), immunoglobulin M (+), immunoglobulin light chi-chain (-), immunoglobulin light lambda-chain (+), LCA (+), L-26(PAN-B)(+), MT-1(-), and UCHL(-). Based on these results, our diagnosis was non-Hodgkin's lymphoma of the diffuse small, lymphoplasmacytoid type.

This study found that oridonin, a natural diterpenoid purified from Rabdosia rubescens, inhibited growth of multiple myeloma (MM; U266, RPMI8226), acute lymphoblastic T-cell leukemia (Jurkat), and adult T-cell leukemia (MT-1) cells with an effective dose that inhibited 50% of target cells (ED50) ranging from 0.75 to 2.7 microg/mL. Terminal deoxynucleotidyltransferase-mediated dUTP nick end labeling staining showed that oridonin caused apoptosis of MT-1 cells in a time-dependent manner. We explored effects of oridonin on antiapoptotic Bcl-2 family members and found that it down-regulated levels of Mcl-1 and BCL-x(L), but not Bcl-2 protein, in both MT-1 and RPMI8226 cells. Further studies found that oridonin inhibited nuclear factor-kappa B (NF-kappa B) DNA-binding activity in these cells as measured by luciferase reporter gene, ELISA-based, and electrophoretic mobility shift assays. Oridonin also blocked tumor necrosis factor-alpha- and lipopolysaccharide-stimulated NF-kappa B activity in Jurkat cells as well as RAW264.7 murine macrophages. Of note, oridonin decreased survival of freshly isolated adult T-cell leukemia (three samples), acute lymphoblastic leukemia (one sample), chronic lymphocytic leukemia (one sample), non-Hodgkin's lymphoma (three samples), and MM (four samples) cells from patients in association with inhibition of NF-kappa B DNA-binding activity. On the other hand, oridonin did not affect survival of normal lymphoid cells from healthy volunteers. Taken together, oridonin might be useful as adjunctive therapy for individuals with lymphoid malignancies, including the lethal disease adult T-cell leukemia.

We studied antitumor effects of receptor tyrosine kinase inhibitor sunitinib (formerly SU11248) against a variety of hematologic malignancies including the following leukemias: eosinophilic (EOL-1), acute myeloid (THP-1, U937, Kasumi-1), biphenotypic (MV4-11), acute lymphoblastic (NALL-1, Jurkat, BALL-2, PALL-1, PALL-2), blast crisis of chronic myeloid (KU812, Kcl-22, K562), and adult T-cell (MT-1, MT-2, MT-4), as well as non-Hodgkin's lymphoma (KS-1, Dauji, Akata) and multiple myeloma (U266). Thymidine uptake studies showed that sunitinib was active against EOL-1, MV4-11, and Kasumi-1 cells, which possessed activating mutations of the PDGFRalpha, FLT-3, and c-KIT genes, respectively, with IC(50)s of <30 nmol/L. In addition, sunitinib inhibited the proliferation of freshly isolated leukemia cells from patients possessing mutations in FLT3 gene. Annexin V staining showed that sunitinib induced apoptosis of these cells. Sunitinib inhibited phosphorylation of FLT3 and PDGFRalpha in conjunction with blockade of mammalian target of rapamycin signaling in MV4-11 and EOL-1 cells, respectively. Interestingly, rapamycin analogue RAD001 enhanced the ability of sunitinib to inhibit the proliferation of leukemia cells and down-regulate levels of mammalian target of rapamycin effectors p70 S6 kinase and eukaryotic initiation factor 4E-binding protein 1 in these cells. Taken together, sunitinib may be useful for treatment of individuals with leukemias possessing activation mutation of tyrosine kinase, and the combination of sunitinib and RAD001 represents a promising novel treatment strategy.

Adult T-cell leukemia/lymphoma (ATL) is a highly aggressive disease in which the human T-cell lymphotropic virus type I (HTLV-I) has been recognized as the etiologic agent. Fludarabine is a purine analog that has demonstrated significant activity in B-cell malignancies, including chronic lymphocytic leukemia and indolent non-Hodgkin's lymphoma. This study explored the effects of fludarabine on HTLV-1-infected T cells (MT-1, -2, -4 and HUT102). Fludarabine induced growth arrest and apoptosis of these cells, as measured by 3-(4,5-dimethylithiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay, cell cycle analysis and annexin V staining. Moreover, exposure of HTLV-1-infected T cells to fludarabine decreased the levels of X-inhibitor of apoptosis protein in conjunction with inhibition of nuclear factor kappaB (NF-kappaB)/DNA-binding activity, as measured by Western blot analysis and electrophoretic mobility shift and reporter gene assays, respectively. Further studies found that fludarabine accumulated NF-kappaB and inhibitory subunit of NF-kappaB in cytosole in conjunction with downregulation of NF-kappaB in nucleus, suggesting that fludarabine blocked nuclear translocation of NF-kappaB. Taken together, fludarabine may be useful for treatment of individuals with ATL and other types of cancer in which NF-kappaB plays a role.
