Abstract
Multiple myeloma (MM) is a malignant neoplasm of plasma cells. Although new molecular targeting agents against MM have been developed based on the better understanding of the underlying pathogenesis, MM still remains an incurable disease. We previously demonstrated that β-catenin, a downstream effector in the Wnt pathway, is a potential target in MM using RNA interference in an in vivo experimental mouse model. In this study, we have screened a library of more than 100 000 small-molecule chemical compounds for novel Wnt/β-catenin signaling inhibitors using a high-throughput transcriptional screening technology. We identified AV-65, which diminished β-catenin protein levels and T-cell factor transcriptional activity. AV-65 then decreased c-myc, cyclin D1 and survivin expression, resulting in the inhibition of MM cell proliferation through the apoptotic pathway. AV-65 treatment prolonged the survival of MM-bearing mice. These findings indicate that this compound represents a novel and attractive therapeutic agent against MM. This study also illustrates the potential of high-throughput transcriptional screening to identify candidates for anticancer drug discovery.

Abstract
To assess the usefulness of 4-hydroperoxycyclophosphamide (4-HC) and Etoposide (VP-16) as a purging agent for myeloma cells in bone marrow ex-vivo, myeloma cell lines (SK-RCS-1, RPMI-8226), lymphoma cell line (SK-DHL-2) and normal bone marrow (BM) cells were treated at different concentrations of 4-HC, VP-16. In separate experiments, LAK cells or antibodies were also used to treat the above cell lines. Clonogenic tumor cells from all three cell lines could be reduced by more than 4 logs, when treated alone or as a mixture with irradiated normal bone marrow cells at a 4-HC concentration of 60 mumol/l. Under similar conditions, approximately 1% of normal BM myeloid progenitor granulocyte-macrophage colony forming cells (CFU-GM) survived. The results with LAK cells and antibodies were also encouraging. These observations support the use of various purging methods for myeloma cells for autologous bone marrow transplantation.

Abstract
Clinical reports have suggested the existence of immunological tolerance to noninherited maternal antigens (NIMA) in human leukocyte antigen (HLA) mismatched allogeneic stem cell transplantation (allo-SCT). We studied the T-cell reactivity using IFN-gamma enzyme-linked immunospot (ELISPOT) assay in three HLA fully matched allo-SCT cases and one healthy volunteer family case. In HLA fully matched allo-SCT cases, ELISPOT assay could detect the hyporesponsiveness of T cells from donors to the B cells from recipients. Moreover, ELISPOT assay showed that the T cells from an individual responded to B cell from his mother significantly weakly than those from an unrelated HLA-haploidentical individual. These observations suggest that our IFN-gamma ELISPOT assay-based method may predict the presence of immunological tolerance to NIMA.

Abstract
BACKGROUND The molecular mechanism of natural killer (NK) cell cytotoxicity to myeloma cells remains unclear. We investigated whether MHC class I-related chain (MIC), a ligand of NKG2D that is an activating NK cell receptor, is involved in the cytotoxicity of NK cells toward myeloma cells, and examined the effects of various drugs on the cytotoxicity. METHODS Two human myeloma cell lines and fresh myeloma cells from 10 patients were used. MIC expression was examined by flow cytometry and reverse transcription (RT)-PCR. NK cell cytotoxicity was examined using a 51Cr-release assay. The effects of various drugs, including thalidomide, all-trans retinoic acid, dexamethasone, IFN-alpha and incadronate, on the MIC expression and NK cell cytotoxicity were examined. RESULTS MIC was highly expressed on the human myeloma cell lines U266 and RPMI-8226 and in myeloma cells of one of 10 patients examined. MIC expression on these cells was not changed by various drugs except IFN-alpha, by which MIC expression was down-regulated. Although MIC and HLA class I molecules were similarly expressed at high levels on both cell lines, U266 was sensitive to NK cells whereas RPMI-8226 was not. Furthermore, cytolysis by NK cells was not inhibited by the addition of anti-MIC Ab or decreased expression of MIC caused by IFN-alpha. DISCUSSION MIC plays a role in the cytolysis by NK cells in multiple myeloma.

Abstract
A 48-year-old man was admitted to our hospital for investigation of mild renal dysfunction. A blood examination revealed mild elevation of creatinine level (1.77 mg/dl). Urinary examination revealed mild protein excretion (0.54 g/day) and microhematuria; renal biopsy revealed the focal proliferation of large mononuclear cells with mitosis in glomerular capillaries. According to immunohistochemical analysis, the intravascular lymphomatous cells stained positively with anti-leukocyte common antigen (LCA: CD45) and CD20, indicating a B lymphocyte lineage. In electron microscopy, the glomerular capillary was filled with lymphoma cells and epithelial foot process fusion was noted. Immunohistochemical analysis on adhesive molecules revealed a lack of CD11a expression on lymphoma cells, but positive CD54 expression on endothelial cells. Systemic 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) revealed no abnormal uptake of isotopes. On the basis of these findings, we diagnosed intravascular diffuse large B cell lymphoma localized in the kidney. Despite treatment with rituximab and CHOP (prednisolone, doxorubicin, vincristine, cyclophosphamide) for 3 cycles at 1-month intervals, the renal dysfunction did not change. In histopathological analysis of the second biopsy, lymphoma cells disappeared, but focal segmental glomerulosclerosis and moderate interstitial fibrosis were noted. Electron microscopic findings revealed severe subendothelial edema with mesangial interposition, indicating severe endothelial damage. Epithelial foot process fusion was improved. These pathological analyses let us conclude that a lack of CD11a could be a candidate factor for prevention of the extravasation of lymphoma cells from blood vessels in our patient. We also presumed that the intraglomerular endothelial damage occurred due to chemotherapy-associated cell injury.

Abstract
The purging efficacy of positive selection of autologous CD34+ PBSC with a clinical scale method of magnetic-activated cell sorting system (CliniMACS) was investigated in 48 patients with non-Hodgkin's lymphoma (NHL). The median purity and recovery rate of the CD34+ cells post-selection were 93.3% (range 32.6-99.3) and 72.2% (range 20.5-309.8), respectively. The real-time PCR method to detect the patient-specific monoclonal immunoglobulin heavy chain gene rearrangement (minimal residual tumor; MRT) and CD19 and CD20 positivities were used for the detection of contaminating NHL cells before and after CD34+ selection. After selection, the median (range) depletion rate of MRT was 2.53 (1.52-4.78) log, and that of CD19+ cell and CD20+ cell was 2.46 (0.74-3.64) log and 2.32 (0.40-4.01) log, respectively. In 41 patients, high-dose chemotherapy was performed, followed by the transplantation of the isolated CD34+ cells. Rapid neutrophil recovery as well as platelet recovery was seen with a median time to reach 0.5 x 10(9)/l neutrophils of 10 days (range 8-13) and 20 x 10(9)/l platelets of 14 days (range 10-34), respectively. The present study demonstrated that CliniMACS is a highly effective positive selection method and a high purging efficacy could be obtained without compromising the hematopoietic reconstitution capacity of the graft in NHL patients undergoing high-dose chemotherapy.

Abstract
With the increasing frequency of haploidentical transplantation, it is becoming more important to establish the degree of HLA mismatch that can be accepted. We retrospectively analyzed clinical data of 50 adult Japanese patients with high-risk hematologic malignancies who underwent allogeneic peripheral blood stem cell transplantation (PBSCT) from two- or three-loci-mismatched related donors with HLA class I and II gene disparities in the graft-versus-host direction. They were treated at 20 transplant centers between 1996 and 2002. In all, 18 patients received unmanipulated PBSC, while 32 received purified CD34+ blood cells. Conventional (n=31) or reduced-intensity (n=19) conditioning regimens were used. Of the 39 patients (78%) who survived for > or =28 days after transplant, 37 (95%) achieved neutrophil engraftment, while graft failure and rejection occurred in two of 39 (5%) and three of 37 (8%) patients, respectively. Stepwise Cox regression analysis revealed a significantly lower incidence of grades II-IV acute GVHD in patients receiving purified CD34+ cells (hazard ratio 0.32; 95% CI 0.12-0.84; P=0.022). By 1 year post transplant, 28 patients (56%) had died of transplant-related problems, including infectious complications (30%). Although the number of patients is small, our data suggest that transplant-related problems, particularly infectious complications, are major obstacles to the success of this therapy.

Abstract
A 17-year-old male with chronic myelogenous leukemia in blast crisis received a non-T cell-depleted (TCD) HLA haplo-identical three-loci mismatched hematopoietic stem cell transplant (HSCT) from his mother. Long-term feto-maternal microchimerism was detected by nested polymerase chain reaction with sequence-specific primer typing. The post-transplantation prophylaxis against graft-versus-host disease (GVHD) was tacrolimus with minidose methotrexate. Sustained engraftment was obtained. Acute GVHD (grade 2) developed, but improved rapidly. Bone marrow aspiration on day 120 showed complete remission. Non-TCD HLA haplo-identical HSCT based on feto-maternal microchimerism might be feasible and has important implications in the selection of alternative family donors in HSCT.

Abstract
We investigated the prognostic significance of genetic polymorphism in glutathione-S transferase mu 1 (GSTM1), glutathione-S transferase theta 1 (GSTT1), NAD(P)H:quinone oxidoreductase (NQO1) and myeloperoxidase (MPO), the products of which are associated with drug metabolism as well as with detoxication, in 193 patients with de novo acute myeloid leukemia (AML) other than M3. Of the patients, 64.2% were either homozygous or heterozygous for GSTT1 (GSTT1(+)), while 35.8% showed homozygous deletions of GSTT1 (GSTT1(-)). The GSTT1(-) group had a worse prognosis than the GSTT1(+) group (P = 0.04), whereas other genotypes did not affect the outcome. Multivariate analysis revealed that GSTT1(-) was an independent prognostic factor for overall survival (relative risk: 1.53; P = 0.026) but not for disease-free survival of 140 patients who achieved complete remission (CR). The rate of early death after the initiation of chemotherapy was higher in the GSTT1(-) group than the GSTT1(+) group (within 45 days after initial chemotherapy, P = 0.073; within 120 days, P = 0.028), whereas CR rates and relapse frequencies were similar. The null genotype of GSTT1 might be associated with increased toxicity after chemotherapy.

Abstract
We immunophenotyped 128 patients with B-cell non-Hodgkin's lymphoma (B-NHL) of various histological subtypes using two-color flow cytometry (FCM), and found that lymphoma cells obtained from 31 patients (24.2%) coexpressed at least one of the following T-cell associated antigens (T-Ag); CD2 (2.3%), CD5 (18.0%) or CD7 (6.3%). Moreover, 3 patients expressed two kinds of T-Ag (CD2/CD5, CD2/CD7 or CD5/CD7) as reported by other investigators. Though we could not find coexpression of CD3, CD4 or CD8 antigen in any patients analyzed in our study, such T-Ag(+) B-NHL have also been reported in the literature. As clinical features, extranodular involvement and higher International Prognostic Index (high and high intermediate) seemed more frequent in T-Ag(+) B-NHL than T-Ag(-) B-NHL in our study. Such prognostic significance of T-Ag expression is also reported by other investigators especially in CD5(+) diffuse large B-cell lymphoma. In addition, two-color FCM for detecting such aberrant T-Ag expression in B-NHL is useful for monitoring the minimal residual disease in the subgroup with T-Ag(+) B-NHL.

Abstract
A 60-year-old woman was referred to our hospital in 1996 due to an abdominal distension in the right lower quadrant. She had undergone a partial resection of a cholesteatoma at the right temporal lobe of the cerebrum 30 years previously, and a ventriculoperitoneal shunt (VPS) tube had been placed with drainage into the right lower peritoneal cavity. The patient developed paralytic ileus in December 1966, and ultrasound and computed tomography of the abdomen revealed a cystic mass in the right lower quadrant without lymphadenopathies or masses. Cytologic examinations of the fluid in the cystic mass revealed signs of malignant lymphoma. After the resection of the cystic mass, lymphoma cells were detected in the fluid, but the wall of the cyst consisted of only fibrous tissues. Results of immunophenotypic analysis of the lymphoma cells by immunocytochemistry or flow cytometry were positive for CD19, CD20, CD22, CD45, and HLA-DR but negative for CD45RO, CD3, CD4, and CD8. The genome of human herpes virus (HHV)-8 was not detected in the lymphoma cells, but Epstein-Barr (EB) nuclear antigen 1 and EB virus (EBV)-encoded small nuclear RNAs were detected. Chromosome analysis by the G-banding method showed complicated abnormalities including der(8)t(2;8)(q31;q24), but Southern blotting analysis suggested that the c-myc oncogene did not participate in the lymphomagenesis. The patient's disease was diagnosed as HHV-8-negative primary effusion lymphoma (PEL). The long-standing inflammatory stimulation by a VPS tube might have contributed to the clonal evolution of EBV-infected lymphocytes. resulting in the development of PEL.

Abstract
Reports of cases of mycobacterial infections after SCT are rare. We report a 30-year-old female with a cutaneous infection of Mycobacterium fortuitum 30 months after allogeneic bone marrow transplantation for acute lymphoblastic leukemia. The patient was successfully treated with surgical debridement followed by oral minocycline and clarithromycin. Mycobacterial infections should be considered in SCT patients with undiagnosed refractory chronic cutaneous infection, and surgical debridement is useful for the diagnosis and treatment of such infections.

Abstract
OBJECTIVE B-cell lymphoma-associated hemophagocytic syndrome (B-LAHS) has been increasingly reported in Asia and is regarded as a variant of intravascular lymphomatosis (IVL). Recently CD5 was reported to be expressed in some cases of diffuse large cell lymphoma and IVL. We therefore examined the expression of CD5 on lymphoma cells in B-LAHS and compared the clinical and laboratory data between CD5+ and CD5- B-LAHS. METHODS The expression of CD5 on lymphoma cells was examined using flow cytometry and immunohistochemical analysis of paraffin sections. The clinical records were reviewed to characterize clinical features. PATIENTS Twelve patients with B-LAHS; ten men and two women, age ranging from 41 to 82 years (median, 63.5 years) were included in this study. RESULTS B-LAHS is characterized by fever and hepatosplenomegaly without lymphadenopathy at the initial presentation. Histological examination showed hemophagocytosis and infiltration of lymphoma cells in the bone marrow, and in some cases intravascular proliferation of lymphoid cells characteristic of IVL. All patients showed increased levels of lactate dehydrogenase, C-reactive protein, ferritin and soluble interleukin-2 receptor. In eight of the twelve patients, lymphoma cells were positive for CD5. But no differences were observed in the clinical or laboratory findings between CD5+ B-LAHS and CD5- B-LAHS. CONCLUSION No clinical differences were observed between CD5+ B-LAHS and CD5- B-LAHS. Further studies are required to elucidate the differences in pathogenesis between these two subgroups of B-LAHS.

Abstract
Interferon-alpha (IFN-alpha) therapy was compared with bone marrow transplantation (BMT) in patients with chronic myelogenous leukemia (CML) in a multicenter, prospective study. Of 254 evaluable patients, 175 received IFN-alpha and 79 received allogeneic BMT, 50 of whom received transplants from human leukocyte antigen (HLA)-identical related donors and 29 from HLA-matched unrelated donors. Complete hematologic response was achieved by 148 patients (89%) in the IFN-alpha group and 53 (78%) in the BMT group. In the IFN-alpha group, a complete cytogenetic response was induced in 25 patients (15%), a partial cytogenetic response in 37 (23%), and a minor cytogenetic response in 41 (25%). At a median follow-up of 38 months, in the IFN-alpha group the predicted 5-year survival rate was 79%, and the predicted 5-year rate of remaining in chronic phase was 66%. In the BMT group the predicted 5-year survival rate was 72% for related-donor BMT and 67% for unrelated-donor BMT. Among low Sokal-risk patients, 5-year survival did not differ between IFN-alpha therapy and BMT, irrespective of age. In higher Sokal-risk patients, survival for related-donor BMT and unrelated-donor BMT tended to be better than that with IFN-alpha therapy in younger patients. On the other hand, in older patients, survival in the BMT group, especially for those receiving unrelated-donor BMT, appeared to be inferior to that in the IFN-alpha group. Unrelated-donor BMT can be recommended for high-risk younger patients. However, for older patients, it should be performed after careful consideration of prognostic factors such as age, Sokal score, and response to IFN-alpha.

Abstract
A 24-year-old woman who suffered from ALL with MLL gene rearrangement received high-dose chemotherapy followed by autologous PBSC transplantation during complete remission (CR). Reverse transcriptase-polymerase chain reaction (RT-PCR) used to detect MLL/LTG4 chimeric mRNA showed no minimal residual disease (MRD) in the graft or bone marrow at the transplantation. However, the leukemia relapsed four months after transplantation. Retrospective analysis of quantitative measurement of Wilms tumor gene (WT-1) mRNA showed an increased level in the bone marrow although it was within the normal range. These observations suggest that careful monitoring of MRD by quantitative measurement of WT-1 mRNA in addition to disease-specific chimeric mRNA is required to predict relapse.

Abstract
Mutations of receptor tyrosine kinases are implicated in the constitutive activation and development of human malignancy. An internal tandem duplication (ITD) of the juxtamembrane (JM) domain-coding sequence of the FLT3 gene (FLT3/ITD) is found in 20% of patients with acute myeloid leukemia (AML) and is strongly associated with leukocytosis and a poor prognosis. On the other hand, mutations of the c-KIT gene, which have been found in mast cell leukemia and AML, are clustered in 2 distinct regions, the JM domain and D816 within the activation loop. This study was designed to analyze the mutation of D835 of FLT3, which corresponds to D816 of c-KIT, in a large series of human hematologic malignancies. Several kinds of missense mutations were found in 30 of the 429 (7.0%) AML cases, 1 of the 29 (3.4%) myelodysplastic syndrome (MDS) cases, and 1 of the 36 (2.8%) acute lymphocytic leukemia patients. The D835Y mutation was most frequently found (22 of the 32 D835 mutations), followed by the D835V (5), and D835H (1), D835E (1), and D835N (1) mutations. Of note is that D835 mutations occurred independently of FLT3/ITD. An analysis in the 201 patients newly diagnosed with AML (excluding M3) revealed that, in contrast to the FLT3/ITD mutation (n = 46), D835 mutations (n = 8) were not significantly related to the leukocytosis, but tended to worsen disease-free survival. All D835-mutant FLT3 were constitutively tyrosine-phosphorylated and transformed 32D cells, suggesting these mutations were constitutively active. These results demonstrate that the FLT3 gene is the target most frequently mutated to become constitutively active in AML.

Abstract
A 40-year-old woman, who had suffered from AML (M1) in 1983, developed ovarian cancer (stage IIIc) in December 1996 after long-term remission. She underwent surgical resection of the cancer, 10 courses of standard chemotherapy and tandem PBSCT (total dose: CBDCA 6,750 mg, CDDP 200 mg, CPA 16,000 mg, THP-ADR 450 mg). After receiving the last course of chemotherapy in June 1998, she was referred to our hospital in September 1998 because of pancytopenia. Laboratory findings showed pancytopenia with 34% leukemic cells, which were positive for alpha NBE and negative for POX and CAE. Surface-marker analysis of the leukemic cells showed positivity for CD11c, CD33, CD56, and DR, and chromosome analysis revealed 47, XX, +8. The patient was diagnosed as having AML (M5a), and received induction therapy consisting of IDR and Ara-C, which led to complete remission. As she had not received etoposide, this case was thought to have been therapy-related leukemia due to the platinum agents used for treating the ovarian cancer.

Abstract
A 52-year-old man was admitted for treatment of acute lymphoblastic leukemia (ALL). The bone marrow was hypercellular with 67.2% blasts, which were negative for peroxidase, and expressed CD13, CD33, CD34, CD10 and CD7. Cytogenetic and molecular studies revealed t(9;22) and -7(Ph/-7) with major BCR/ABL rearrangement. The patient was treated with the L-AdVP regimen, but failed to achieve complete remission (CR). He then received two courses of chemotherapy consisting of intermediate- and high-dose cytarabine (ara-C), resulting in CR. This case suggests that Ph/-7 ALL with major BCR/ABL gene rearrangement showing coexpression of myeloid antigens may be sensitive to intermediate- and high-dose ara-C.

Abstract
Four patients (three males and one female) were diagnosed as myeloid/natural killer (NK) cell precursor acute leukemia in our department. Two patients showed the extramedullary involvement at initial presentation. Leukemic cells expressed CD7, CD33, CD45 and CD56 in all patients. Additionally, CD13, CD34, HLA-DR, cytoplasmic CD3 and myeloperoxidase were expressed in some patients. Trisomy 10 was found in two patients, which has not been reported in this disease. Therefore, myeloid/NK cell precursor acute leukemia might be rather heterogeneous especially in chromosomal abnormality though it seemed to constitute the distinct clinical entity among acute myeloid leukemia of M0 subtype.

Abstract
We examined the effect of YM529, a newly developed third-generation bisphosphonate (BP), on the growth of human myeloma cell lines using the trypan blue dye exclusion test and Alamar blue assay. BPs induced inhibition of proliferation in all cell lines dose-dependently, and YM529 had a most potent growth inhibitory effect, followed by incadronate and pamidronate. Flow cytometric analysis using annexinV and 7AAD showed that YM529 most significantly induced apoptosis of all myeloma cell lines. These observations suggested that YM529 is a potent apoptosis inducer of myeloma cells, and might have some benefit not only on the improvement of bone lesions but also on survival in some myeloma patients.

Abstract
Several genetic polymorphisms in metabolic activation or detoxification enzymes have been associated with susceptibility to therapy-related leukemia and myelodysplastic leukemia (TRLIMDS). We analyzed gene polymorphisms of NAD(P)H:quinone oxidoreductase (NQOl), glutathione S-tranferase (GST)-MI and -TI, and CYP3A4, the enzymes of which are capable of metabolizing anticancer drugs, in 58 patients with TRL/MDS and in 411 patients with de novo acute myeloid leukemia (AML). Homozygous Ser/Ser genotype of NQOl at codon 187, causing loss of function, was more frequent in the patients with TRLIMDS (14 of 58, 24.1%; OR = 2.62) than in those with de novo AML (64 of 411, 15.6%), and control (16 of 150, 10.6%; P = 0.002). Allelic frequencies of NQOJ were different between TRL/ MDS and de novo AML (P = 0.01). In GST-MJ and -Ti, the incidence of homologous deletion was similar among the three groups. The polymorphism of the 5' promoter region of CYP3A4 was not found in persons of Japanese ethnicity. These results suggest that the NQOJ polymorphism is significantly associated with the genetic risk of TRLIMDS.

Abstract
A 21-year-old man, diagnosed in March 1997 as having chronic myelogenous leukemia (CML), received hydroxyurea followed by daily interferon (IFN) until December 1998, when the additional chromosome abnormality of +8 appeared. As no suitable matched donor was available, the patient received mobilization therapy consisting of mini-ICE (idarubicin, cytarabine, etoposide) followed by G-CSF subcutaneously. During hematopoietic recovery, a total of 12 x 10(6)/kg CD34-positive cells were harvested. Cytogenetic analysis of peripheral blood stem cell (PBSC) products using FISH revealed 1% BCR/ABL fusion signals. In March 1999, he received conditioning therapy consisting of busulfan (16 mg/kg) and cyclophosphamide (120 mg/kg) followed by infusion of 5 x 10(6)/kg CD34-positive cells. A neutrophil count of 500/microliter and a platelet count of 5 x 10(4)/microliter were attained by days 20 and 38, respectively. Bone marrow aspirates showed 2.6% BCR/ABL fusion signals on day 35 after autologous PBSC transplantation, and the patient remained in chronic phase until the sixth month, when a cytogenetic relapse (Ph, +8:4/20) occurred. These observations suggest that Ph-negative progenitor cells can be harvested using a mini-ICE regimen followed by G-CSF, and that autologous PBSC transplantation is feasible in patients with CML resistant to IFN.

Abstract
Forty-nine adult patients with high-risk myelodysplastic syndrome (MDS) or acute myeloid leukemia that progressed from MDS were registered for the multicenter study of the Japan Adult Leukemia Study Group. Forty-three patients were evaluable for the analysis. Idarubicin 12 mg/m2 per day for 3 days and continuous cytosine arabinoside 100 mg/m2 per day for 7 days were given as induction therapy, followed by postremission chemotherapy after complete remission (CR). Because elderly patients and those with hypoplastic marrow usually have complications after intensive chemotherapy, often causing early death, the treatment dose was reduced to 60% or 80% according to the presence of 3 risk factors: age 60 years or older, performance status 2 or more, or presence of hypoplastic bone marrow. Of the 43 evaluable patients (median age, 58 years), 26 (60%) achieved CR. Two patients (5%) died within 2 months of completion of induction therapy. The CR rates for patients treated with 100%, 80%, and 60% of the chemotherapy dose were 55% (12 of 22), 63% (10 of 16), and 80% (4 of 5), respectively, indicating that the risk factor-adjusted dose attenuation was appropriately applied to those who might have had problems with the original dose, thus reducing regimen-related mortality rate. The median overall survival of the 43 patients was 8 months.

Abstract
In acute myeloid leukemia (AML), p53 mutations are reportedly infrequent but associated with a poor prognosis. The majority of mutations are missense mutations, which generally lead to accumulation of nuclear p53 protein. However, the prognostic significance of the accumulation remains unknown in AML. In this study, we compared the prognostic value of p53 mutations versus accumulation of the product. p53 mutations were found in 9 (4.5%) of 200 patients with de novo AML. The p53 mutation detectable (mutation+) group had a worse prognosis (p = 0.0009) than the mutation not detectable (mutation-) group. Multivariate analysis showed that the p53 mutation was an independent factor (p = 0.005) for short overall survival as well as 60 yr or older (p = 0.001) and unfavorable karyotypes (p = 0.001). In 79 of the 200 patients, the expression of p53 was studied by immunocytochemistry (ICC) using anti-p53 monoclonal antibody (DO-7). All samples carrying missense mutations (N = 6) were positive for ICC in over 15% of nuclei of each sample, chosen as the optimized cutoff value of p53 accumulation. Accumulation was thus found in 14 of the 79 patients. However, there was no prognostic difference according to the accumulation, because the mutation-/accumulation+ group (N = 8) tended to have a good prognosis. These findings indicate that molecular detection of p53 mutations yields better prognostic information than ICC. In a subset of AML, p53 protein might be accumulated without mutation presumably due to upstream signals of p53.

Abstract
We performed the immunophenotyping of 101 patients with B-cell non-Hodgkin's lymphoma (B-NHL) using two-colour flow cytometry (FCM) and found that lymphoma cells coexpressed at least one kind of T-cell-associated antigen (T-Ag; CD2, CD5, CD7) in 25 patients (24. 8%). Among these three T-Ags, CD5 was the most frequently expressed, in 21 patients (20.8%), followed by CD7, expressed in five patients (5.0%), and CD2, which was expressed in two patients (2.0%). Two kinds of T-Ag were simultaneusly expressed in three patients (CD2/CD5, CD2/CD7, and CD5/CD7, each expressed in one patient). Concerning the expression pattern of T-Ag, there were no significant differences between lymph nodes and extranodal organs in the three patients with T-Ag-positive B-NHL (T-Ag(+) B-NHL) who were analysed. When comparing the clinical features between T-Ag(+) B-NHL and T-Ag-negative B-NHL (T-Ag(-) B-NHL), extranodal involvement and higher International Prognostic Index (H and H.I.) were significantly frequent in the former subgroup (P = 0.0119 and P = 0. 0302 respectively).

Abstract
This pilot study evaluated the efficacy of a new combination chemotherapy with a newly developed nitrosourea derivative ranimustine and evaluated the efficacy of interferon alpha (IFN-alpha) maintenance in previously untreated patients with multiple myeloma (MM). The induction therapy (ROAD-IN) was a 6-week regimen consisting of chemotherapy with ranimustine, vincristine (Oncovin), melphalan (Alkeran) and dexamethasone starting on day 1 and IFN-alpha, which was administered three times weekly for 3 weeks starting on day 22. This was repeated for three cycles. The responders were subsequently randomized into two groups that received or did not receive IFN-alpha as maintenance therapy. Of the 164 patients registered, 161 were evaluated. An objective response to induction therapy was seen in 75% of patients; complete remission (CR) in 38 (24%) and partial remission (PR) in 82 (51%). The median survival for all patients was 3.6 years from registration. The survival of responders (CR + PR) was significantly better than that of non-responders (median survival 4.3 years vs. 1.4 years; 7-year survival rate 32% vs. 9%; P < 0.0001). The IFN-alpha maintenance did not show any advantage for either response duration or survival. This pilot study demonstrated that a comparatively short period of induction therapy with the ROAD-IN regimen produced a rather high response rate and a similar survival rate to those achieved with other longer induction regimens, and that good responders to the initial therapy survived significantly longer than non-responders.

Abstract
B-cell lymphoma-associated hemophagocytic syndrome (B-LAHS) is extremely rare in Western countries but has recently been increasingly reported in Asian countries, especially Japan. Here, we reviewed 25 previously reported Japanese cases of B-LAHS and summarized its clinicopathologic features and therapeutic outcome. The median age of onset was 63 years old with initial presentation of fever, hepatomegaly, and splenomegaly without associated lymphadenopathy. Laboratory findings showed increased levels of lactate dehydrogenase, C-reactive protein, ferritin and soluble interleukin-2 receptor. Histopathologically, hemophagocytosis was often seen in the bone marrow and spleen. Various percentages of lymphoma cells were seen in the bone marrow, positive for CD19, CD20 and surface immunoglobulin. and some were also positive for CD5. Cytogenetic analysis showed a complex structural abnormality including chromosome 14q32, 19q13 and deletion of the terminal part of 8p21. Some patients had histological features of intravascular lymphomatosis (IVL). The prognosis was poor with a median survival period of 9 months. We treated five patients using autologous peripheral blood stem cell transplantation (PBSCT), and four are still in complete remission nine to 24 months after PBSCT, suggesting that high-dose chemotherapy followed by PBSCT might improve the survival rate.

Abstract
OBJECTIVE One of the mechanisms for mobilization of hematopoietic stem cells and progenitor cells is alternation of adhesion molecules. We investigated the mobilization of hematopoietic progenitor cells in blood by administration of anti-vascular cell adhesion molecule (VCAM)-1 antibody (Ab) in mice. MATERIALS AND METHODS Twelve- to 14-week old C57BL/6J mice were injected intravenously with anti-VCAM-1 Ab and anti-very late antigen (VLA)-4 Ab at a dose of 5 mg/kg for 2 days. RESULTS The number of colony-forming cells (CFCs) in blood was increased 11.4-fold after anti-VCAM-1 Ab treatment, but the number of CFCs was not increased after treatment with anti-VLA-4 Ab. The number of colony-forming unit spleen (CFU-S) also was increased 21.6-fold in the peripheral blood by administration of anti-VCAM-1 Ab. The number of CFCs and CFU-S in the bone marrow of mice treated with anti-VCAM-1 Ab was decreased and that in the spleen also was decreased. On administration of recombinant human granulocyte colony-stimulating factor (125 microg/kg twice daily) with anti-VCAM-1 Ab, the numbers of CFCs and CFU-S were increased 141.8-fold and 439-fold, respectively. CONCLUSIONS These observations demonstrated that administration of anti-VCAM-1 Ab induced mobilization of hematopoietic progenitor cells into blood from bone marrow and spleen and that granulocyte colony-stimulating factor has synergistic effects on anti-VCAM-1 Ab-induced mobilization.

Abstract
A 47-year-old man was admitted to our hospital in June 1997 because of nasal bleeding. He presented with anemia in addition to physical characteristics of Werner's syndrome (WS). Peripheral blood examination disclosed pancytopenia with 4% blasts. Bone marrow aspiration was a dry tap; biopsy specimens revealed myelofibrosis. Chromosomal analysis of peripheral blood revealed hypodiploidy with complex abnormalities including -5 and del(7)(q21). Serum levels of PDGF, FGF, and TGF beta 1 were normal. A diagnosis of acute myelofibrosis was made. The patient's condition became quickly deteriorated and he died of pneumonia in October 1997. In the literature, we found 6 reported cases of myelofibrosis associated with WS. Considering that only approximately 1,100 cases of WS have been reported so far, the incidence of myelofibrosis in WS seems relatively high. This case suggested a link between WS and myelofibrosis, and the mechanism of myelofibrosis in WS was discussed.

Abstract
Wilms' tumor (WT1) gene expression is increased in patients with leukemia as well as myelodysplastic syndrome (MDS) and is useful for detection of minimal residual disease (MRD). A 47-year-old man given a diagnosis of refractory anemia with excess of blasts in transformation (RAEB-T) received myeloablative therapy followed by autologous peripheral blood stem cell transplantation (PBSCT). MRD by WT1 expression was not detected in the graft. The patient has been in CR for 25 months after PBSCT. These observations suggest that PBSCT is feasible for patients with RAEB-T and analysis of WT1 expression can be applied for patients with high risk MDS.

Abstract
A 59-year-old man was admitted in December 1995 because of general fatigue without lymphadenopathy. Increased abnormal lymphocytes (70%) were observed in peripheral blood. Bone marrow aspiration was a dry tap. Biopsy specimens revealed hypercellularity with infiltration of abnormal lymphocytes. Surface marker analysis of tumor cells was positive for CD5, CD19, CD20, HLA -DR, kappa, and sIgM and negative for CD10. Cytogenetic analysis disclosed a complex abnormal karyotype including t(3;22) and rearrangement of the BCL6 gene. The patient was given a diagnosis of CD5 positive B-cell lymphoma, but died in January 1997 despite repeated chemotherapy. This case was unique because BCL6 rearrangement has been reported in various types of B-cell lymphoma but rarely associated with leukemic types without lymphadenopathy.

Abstract
We conducted a multicenter early phase II study to evaluate the feasibility and therapeutic efficacy of high-dose chemotherapy supported by autologous peripheral blood stem cell transplantation (auto-PBSCT) for the treatment of intermediate grade non-Hodgkin's lymphoma (IG-NHL). High-dose etoposide or cyclophosphamide followed by G-CSF was used for PBSC mobilization, and a sufficient number of CD34+ cells (> 1 x 10(6)/kg) were collected. Out of 81 enrolled patients, 50 received high-dose chemotherapy with auto-PBSCT; Hematologic recovery after transplantation was rapid. The incidence of grade III/IV toxicity (Bearman) was about 6%; treatment-related mortality was 6% (3/50). The Disease-free survival rate for the patients in complete remission who received high-dose chemotherapy with auto-PBSCT was better than that for the patients who were treated with conventional chemotherapy (57% vs 35%). These preliminary results indicated that high-dose chemotherapy with auto-PBSCT is feasible and effective. A prospective randomized phase III clinical trial will be required to assess the efficacy of high-dose chemotherapy with auto-PBSCT as a post-remission therapy for IG-NHL.

Abstract
To assess the efficacy of etoposide added to the standard remission induction therapy for acute myeloid leukemia (AML), newly diagnosed adult AML patients were randomized to receive either daunorubicin (40 mg/m2/day x 4 or more), behenoyl cytarabine (200 mg/m2/day x 10 or more), and 6-mercaptopurine (70 mg/m2/day x 10 or more) (BHAC-DM), or the same three drugs plus etoposide (100 mg/m2/day x 5) (BHAC-EDM) for response-oriented individualized induction therapy. The patients achieving complete remission (CR) received the same 3 courses of consolidation therapy followed by 6 courses of maintenance/intensification therapy. M3 patients were excluded because all-trans retinoic acid was used. Of 667 patients registered, 655 were evaluable. The median age was 49 (range 15 to 85). CR rates were 77% in the BHAC-DM group and 75% in the BHAC-EDM group. In 173 M4 patients, CR rates were 86% and 69% (P = 0.009), and in 32 M5 patients, 80% and 77% (P = 0.810) in the BHAC-DM and the BHAC-EDM groups, respectively. The predicted 6-year overall survival rates were 30% and 38% (P = 0.925) for the BHAC-DM and BHAC-EDM groups, and the disease-free survival rates of CR patients were 25% and 35% (P = 0.352), respectively. Nonhematological toxicities after the first course of induction therapy were almost equal among the two groups, with the exception of a greater loss of hair (P = 0.024) and more frequent diarrhea (P = 0.013) in the BHAC-EDM group. We concluded that in the present study, the addition of etoposide to the standard individualized induction therapy showed no advantage in adult AML, even among M4 and M5 patients.

Abstract
Internal tandem duplication of the FLT3 gene and point mutations of the N-RAS gene are the most frequent somatic mutations causing aberrant signal-transduction in acute myeloid leukemia (AML). However, their prognostic importance is unclear. In this study, their prognostic significance was analyzed in 201 newly diagnosed patients with de novo AML except acute promyelocytic leukemia. Three patients had mutations in both genes, 43 had only the FLT3 gene mutation, 25 had only the N-RAS gene mutation, and 130 had neither. These mutations seemed to occur independently. Both mutations were related to high peripheral white blood cell counts, and the FLT3 gene mutation was infrequently observed in the French-American-British (FAB)-M2 type. AML cases with wild FLT3/mutant N-RAS had a lower complete remission (CR) rate than those with wild FLT3/wild N-RAS, whereas the presence of mutant FLT3 did not affect the CR rate. Univariate analysis showed that unfavorable prognostic factors for overall survival were age 60 years or older (P =.0002), cytogenetic data (P =.002), FAB types other than M2 (P =.002), leukocytosis over 100 +/- 10(9)/L (P =.003), and the FLT3 gene mutation (P =.004). However, the N-RAS gene mutation was only a marginal prognostic factor (P =.06). For the subjects under 60 years old, multivariate analysis showed that the FLT3 gene mutation was the strongest prognostic factor (P =.008) for overall survival. The FLT3 gene mutation, whose presence is detectable only by genomic polymerase chain reaction amplification and gel electrophoresis, might serve as an important molecular marker to predict the prognosis of patients with AML.

Abstract
A 58-year-old man was admitted to our hospital in November 1992 because of fever and arthralgia. He was given a diagnosis of acute lymphoblastic leukemia and treated with an Ad-VP regimen, which resulted in complete remission. After two courses of consolidation therapy and intrathecal (IT) injections of methotrexate, Ara-C, and prednisolone the patient received high-dose Ara-C plus VP-16 followed by recombinant human G-CSF for the collection of peripheral blood stem cells. However, he relapsed with the appearance of leukemic cells in cerebrospinal fluid (CSF), and was accordingly given IT injections 8 more times. After the disappearance of leukemic cells from CSF, the patient received a peripheral blood stem cell transplant (PBSCT) and achieved rapid hematopoietic recovery. However, he suffered mental aberrations and loss of consciousness 9 days after PBSCT. Proton magnetic resonance spectroscopy (1H-MRS) disclosed severe necrosis due to leukoencephalopathy in the frontal lobe and invasion of leukemic cells around the lateral ventricles. The patient did not receive any therapy for neurological symptoms because of severe necrosis in the frontal lobe, and died of bone marrow relapse in April 1995. MRS is useful for the discrimination of leukoencephalopathy from leukemic cell invasion.

Abstract
B-cell lymphoma associated with haemophagocytic syndrome (HPS) is extremely rare in Western countries but has recently been increasingly reported in Asian countries. We describe seven patients with B-cell lymphoma associated with HPS, six males and one female, age range 41-82 years (median 63 years). All patients had fever and splenomegaly, and six of the seven patients had hepatomegaly with no associated lymphadenopathy. The bone marrow showed haemophagocytosis and an infiltration of lymphoma cells. All patients showed increased levels of lactate dehydrogenase, C-reactive protein, ferritin and soluble interleukin-2 receptor. Lymphoma cells were positive for CD19. CD20 and surface immunoglobulin in all patients examined, and positive for CD5 in four of seven patients. Cytogenetic analyses of bone marrow cells showed a complex structural abnormality including chromosome 14q32 in two patients, 19q13 in three patients and deletion of the terminal part of 8p21 in six patients. The prognosis was poor; only two of the seven patients have survived in complete remission with a median survival of 11 months. These data suggested that B-cell lymphoma associated with HPS might constitute a distinct biological and clinical disease entity. Abnormality of chromosome 19q13 and loss of 8p21 might be involved in the pathogenesis of this disease.
