Abstract
Abstract
Background
Underlying plaque characteristics that lead to future revascularization during long-term follow-up remain poorly understood.
Purpose
We aimed to explore intracoronary imaging-derived measures as assessed by intravascular ultrasound (IVUS) and optical coherence tomography (OCT) associated with non-infarct related vessel revascularization (non-TVR) arising from imaged segments during long-term (up to 7 years) follow-up among patients with ST-elevated myocardial infarction (STEMI).
Methods
A total of 94 STEMI patients enrolled into the IBIS-4 (Integrated Biomarker Imaging Study-4) study undergoing serial (baseline and 13 months) IVUS and OCT in 2 non-infarct-related coronary arteries under high-intensity statin therapy were analyzed in the present study. Patients were divided into 2 groups according to the occurrence of non-TVR within previously imaged vessel segments (non-TVR: n=14, no non-TVR: n=80).
Results
Baseline characteristics including LDL level were comparable between groups. At baseline, lesions with future non-TVR were associated with greater percent atheroma volume by IVUS (55.6±5.4% vs. 49.6±6.1%, P<0.001), minimum lumen area by OCT (3.4±1.7 mm2 vs. 6.0±3.3 mm2, P=0.004), and a higher prevalence of fibroatheroma (60.0% vs. 20.1%, P=0.007) by OCT compared with those without. Among patients with serial imaging, lesions with non-TVR had a trend towards a less reduction of percent atheroma volume (−0.2±3.8% vs. −2.4±4.2%, P=0.083).
Conclusion
Greater plaque burden, smaller lumen area, and higher prevalence of OCT-detected fibroatheroma at baseline were associated with non-infarct related vessel revascularization. Lesions with non-TVR tend to have less-pronounced regression of coronary atheroma despite intensive statin therapy and achieved LDL levels.

Abstract
Treatment outcomes for chronic myelogenous leukemia (CML) have shown major improvements as a result of the development of the tyrosine kinase inhibitors (TKIs) imatinib, nilotinib and dasatinib for the disease-specific molecular target BCR-ABL1 tyrosine kinase (TK), but a cure of CML by BCR-ABL1 TKIs has been rarely achieved. CML cells are protected from cytotoxic insults, including those by TKIs, through various collaborative BCR-ABL1- mediated and -independent mechanisms, as well as cell-intrinsic and -extrinsic molecular mechanisms. These protective mechanisms include overlapping cell signaling pathways for normal hematopoietic proliferation, modulation of molecules associated with the BCL2 family protein-regulated programmed cell death pathway, autophagic cell protection capability, bone marrow environment-mediated cell protective signaling, abnormally upregulated genetic instability and other BCR-ABL1- independent kinase activities. To develop a more effective treatment strategy for a cure by means of total leukemic cell killing, a thorough understanding of how CML cells survive and resist cytotoxic insults is essential. In this article, we review current knowledge about multifaceted BCR-ABL1-related and -unrelated mechanisms for survival and death of CML cells and present suggestions for the development of new therapeutic strategies for complete elimination of residual CML cells during TKI treatment.

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
PURPOSE To evaluate the clonal relatedness and drug susceptibility of Streptococcus epidermidis isolated from hematological patients. METHODS All S. epidermidis isolated from hematological patients who developed bloodstream infections between June 2005 and December 2007 were included. The clonal relationship was tested by means of pulsed-field gel electrophoresis (PFGE) analysis. RESULTS Fifteen methicillin-resistant S. epidermidis (MRSE) isolates were examined from patients' blood culture samples. Two subgroups that differed approximately by 40% in their PFGE banding were identified. In clinical practice, two cases were cured with cephalosporin only, thus demonstrating sensitivity of the strains to beta-lactam antibiotics. CONCLUSIONS Our results represent two significant findings. One is the major capability of MRSE to colonize patients. The other is that some MRSE isolates proved to be sensitive to clindamycin, minocycline, and cephalosporin, so that using antibiotics to which MRSE is sensitive as first-line therapy can avoid the need for vancomycin in clinical settings.

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
17515 Background: Dasatinib is a potent, orally active, multi-targeted kinase inhibitor of BCR-ABL and SRC family kinases. Studies outside Japan have shown dasatinib to be highly effective in overcoming resistance and intolerance to imatinib, inducing durable cytogenetic (CyR) and hematologic responses (HR) in this population. The maximum tolerated dose was not reached in the Phase-I trial outside Japan and a 70-mg BID dose was determined to provide the optimal benefit-risk profile. Methods: This Phase-I/-II study was designed to assess the safety and efficacy of dasatinib in Japanese patients with imatinib-resistant or -intolerant CML or Ph+ALL. In the 4-week Phase-I portion in patients with chronic-phase (CP) CML, three dose levels were evaluated: 50 mg, 70 mg, and 90 mg BID. The Phase-II portion is currently evaluating the CyR of dasatinib in patients with CP-CML at 24 weeks, and the HR rate in accelerated- (AP) or blast-phase (BP) CML and Ph+ ALL at 12 weeks. Results: As of December 2006, 17 eligible patients have been treated in Phase I. Six patients (4F, 2M; median age 43 y [range 27–56]) were treated with 50 mg BID and 1 dose-limiting toxicity (DLT) was observed (Grade 4 thrombocytopenia). Two patients experienced transient Grade 3 ALT elevations but as treatment was uninterrupted, these were not considered DLTs. Six patients (6M; median age 42 y [range 27–55]) were treated with 70 mg BID and again 1 DLT was observed (Grade 4 thrombocytopenia). No DLT has been observed among 4 patients (3M, 1F; median age 41 y [range 27–64]) at the 90-mg BID dose. Major CyRs have been achieved in all three cohorts in the Phase-I segment of the trial. Thirty six patients were enrolled and treated in the Phase-II part of the trial (12 CP-CML, 7 AP- CML, 4 BP-CML, and 13 Ph+ALL). Efficacy and safety data as well as the baseline BCR-ABL mutation data are currently being assessed and will be presented. Conclusions: Dasatinib can be safely administered at doses of up to 90 mg BID to Japanese patients with imatinib-resistant or -intolerant CP-CML. No significant financial relationships to disclose.

Abstract
Bcr-Abl is the cause of Philadelphia-positive (Ph(+)) leukemias and also constitutes their principal therapeutic target, as exemplified by dramatic effects of imatinib mesylate. However, mono-targeting of Bcr-Abl does not always achieve complete leukemia eradication, and additional strategies those enable complete elimination of leukemic cells are desired to develop. Here we demonstrate that INNO-406, a much more active Bcr-Abl tyrosine kinase inhibitor than imatinib, augments the activities of several proapoptotic Bcl-2 homology (BH)3-only proteins (Bim, Bad, Bmf and Bik) and induces apoptosis in Ph(+) leukemia cells via Bcl-2 family-regulated intrinsic apoptosis pathway. ABT-737, an inhibitor of antiapoptotic Bcl-2 and Bcl-X(L), greatly enhanced the apoptosis by INNO-406, even in INNO-406-less sensitive cells with Bcr-Abl point mutations except T315I mutation. In contrast, co-treatment with INNO-406 and other pharmacologic inducers of those BH3-only proteins, such as 17-allylaminogeldanamycin, an heat shock protein-90 inhibitor, or PS-341, a proteasome inhibitor, did not further increase the BH3-only protein levels or sensitize leukemic cells to INNO-406-induced apoptosis, suggesting a limit to how much expression levels of BH3-only proteins can be increased by anticancer agents. Thus, double-barrelled molecular targeting for Bcr-Abl-driven oncogenic signaling and the cell protection by antiapoptotic Bcl-2 family proteins may be the rational therapeutic approach for eradicating Ph(+) leukemic cells.

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
AIMS Lymphomatous polyposis (LP) is considered to represent mantle cell lymphoma (MCL) of the gastrointestinal (GI) tract. However, a few reports have suggested that some are follicular lymphoma (FL) or mucosa-associated lymphoid tissue (MALT) lymphomas. In this study, we analysed 35 patients and clarified the clinicopathological features of LP. METHODS AND RESULTS Paraffin-embedded tissue samples were stained immunohistochemically and analysed by tissue-fluorescence in situ hybridization (T-FISH) for IGH/CCND1 (cyclin D1) and IGH/BCL2. The average age of the patients was 58.3 years. Over half of the cases showed gastric, duodenal, small intestinal, ileocaecal and sigmoid colonic lesions (15, 19, 15, 16 and 16 cases, respectively). Phenotypically, cases were classified into three types of MCL (cyclin D1+ CD5+ CD10-) (n=12), FL (cyclin D1- CD5- CD10+) (n=14) and MALT (cyclin D1- CD5- CD10-) (n=9). T-FISH identified 11 of the 11 examined cases with MCLs to have IGH/CCND1, while seven of 10 cases with FL had IGH/BCL2, and none of the MALT cases were positive for IGH/CCND1 or IGH/BCL2. At the study endpoint, five of 12 patients with MCL were dead, two of 14 with FL and one of nine with MALT were dead of other disease. Event-free survival analysis showed significantly poorest outcome in MCL, followed by FL, while MALT was associated with a favourable outcome (P=0.0040). CONCLUSIONS Our study emphasizes the importance of differentiating MCL, FL and MALT of LP in evaluating prognosis and hence the most suitable therapeutic regimen.

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
A 72-year-old man was admitted to our hospital to undergo a novel small-intestinal endoscopic procedure. He had had occasional episodes of hematochezia over a 2-year period, during which he had been hospitalized twice previously. However, numerous investigations, including hematological and biochemical studies, gastroscopy, colonoscopy, computed tomography, scintigraphy, and angiography had failed to detect the source of bleeding in the gastrointestinal tract. On this admission, double-balloon enteroscopy was performed and revealed several ulcer scars with localized dilation of the ileum. Histopathological examination of the biopsy specimens revealed no abnormal findings. Partial resection of the ileum was performed to prevent further gastrointestinal bleeding, and histopathological examination of the resected specimen revealed aggregation of atypical lymphocytes, predominantly in the muscularis propria layer. Immunohistochemical examination demonstrated that the tumor cells were positive for CD20 and BCL2, but negative for UCHL1. Based on these findings, the lesion was diagnosed as a marginal-zone B-cell lymphoma of mucosa-associated lymphoid tissue. Eighteen months after surgery, the patient was still in complete remission.

Abstract
BACKGROUND To evaluate the efficacy and feasibility of rituximab monotherapy in Japanese patients with relapsed or refractory aggressive B-cell lymphoma. PATIENTS AND METHODS Sixty-eight patients were treated with rituximab at 375 mg/m(2) by eight consecutive weekly infusions. Pretreatment variables affecting overall response rate (ORR) and progression-free survival (PFS) and the relationship between pharmacokinetic parameters and efficacy were analyzed. RESULTS The ORRs of 68 enrolled patients and 57 eligible patients were 35% [95% confidence interval (CI) 24% to 48%] and 37% (95% CI 25% to 51%), respectively. Median PFS of 53 evaluable patients was 52 days, whereas time to progression of 21 eligible responders was 245 days. Mild to moderate infusion-related toxicities were observed frequently at the first infusion, but all of them were reversible. Elevated lactate dehydrogenase (LDH) and refractoriness to prior chemotherapy were unfavorable factors affecting ORR and PFS (P <0.01). Serum trough levels of rituximab and area under the concentration-time curve for responders were higher than for non-responders (P <0.05). CONCLUSIONS Eight consecutive weekly infusions of rituximab have significant anti-lymphoma activity for relapsed or refractory aggressive B-cell lymphoma. Several pretreatment variables and serum rituximab levels are useful for predicting its efficacy.

Abstract
Chromosomal band 1p34-36 is a commonly rearranged locus in many types of cancers. We cloned the breakpoint region of a chromosomal translocation, t(1;14)(p34;q32), found in the human multiple myeloma (MM) cell line, ODA. This rearrangement occurred between the nearby switch region of the immunoglobulin heavy chain (IgH) gene (Sgamma3) at 14q32 and the first intron of the human retinoic acid-inducible E3 protein (E3)/lysosome-associated protein, transmembrane-5 (LAPTm5) gene at the 1p34 locus. Consequently, the E3 gene, which is a hematopoietic cell-specific transcript induced by retinoic acid and located at the rearranged allele, was interrupted within its coding region and was not expressed in the ODA cell line in spite of the other allele still being intact. The expression derived from the remaining intact allele in ODA cells was silenced by DNA methylation at sequences within the first intron around a GC-rich EagI site. Interestingly, the silenced expression of E3 mRNA due to DNA methylation of intron 1 sequences was frequently encountered in MM cells [6/10 (60%) of MM cell lines tested], while E3 is expressed in normal plasma cells and in most other hematopoietic cell lines including those of B-cell lineage. Thus, as the E3 protein has been suggested to be involved in cellular differentiation and apoptotic pathways in certain cell types, our results suggest that loss of E3 gene expression might be a crucial event during the progression of human MM.

Abstract
t(8;21)(q22;q22) is the most frequently observed karyotypic abnormality associated with acute myeloid leukemia (AML), especially in FAB M2. Clinically, this type of AML often shows eosinophilia and has a high complete remission rate with conventional chemotherapy. t(8;21) AML is also frequently associated with additional karyotypic aberrations, such as a loss of the sex chromosome; however, it is unclear whether these aberrations change the biological and clinical characteristics of t(8;21) AML. To investigate this issue, 94 patients with t(8;21) AML were categorized according to their additional karyotypic aberrations, which were detected in more than three cases, and then morphologic features, phenotypes, expression of cytokine receptors, and clinical features were compared to t(8;21) AML without other additional aberrant karyotypes. t(8;21) AML with loss of the sex chromosome and abnormality of chromosome 9 were found in 27 cases (29.3%) and 10 cases (10.6%), respectively; however, no differences were observed from the t(8;21) AML without other additional karyotypes in terms of morphological and phenotypic features. There was also no significant difference in the clinical outcome among these three groups. On the other hand, trisomy 4 was found in three cases (3.2%) and these cells showed low expressions of CD19 (P=0.06) and IL-7 receptor (P=0.05), and high expressions of CD33 (P=0.13), CD18 (P=0.03), and CD56 (P=0.03) when compared to t(8;21) AML without additional karyotypes. Moreover, all three t(8;21) AML cases with trisomy 4 did not show eosinophilia in their bone marrow and died within 2.4 years. These observations suggest that additional karyotypic aberration, t(8;21) with trisomy 4 is rare, but it may constitute a distinctive subtype of t(8;21) AML.

Abstract
BACKGROUND CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone) is accepted as the best available standard treatment for first-line chemotherapy in aggressive non-Hodgkin's lymphoma (NHL). However, the therapeutic efficacy of CHOP remains unsatisfactory, particularly in high-intermediate risk and high risk patients, and a new strategy is warranted in this patient population. The aim of the present study was to explore a suitable therapeutic-intensified regimen for the treatment of aggressive NHL. PATIENTS AND METHODS Between May 1995 and July 1998, a total of 70 patients with high-intermediate risk or high risk aggressive NHL, according to the International Prognostic Index, were enrolled and randomly assigned to receive either eight cycles of standard CHOP (cyclophosphamide 750 mg/m(2), doxorubicin 50 mg/m(2), vincristine 1.4 mg/m(2) and prednisolone 100 mg for 5 days) every 2 weeks, or six cycles of dose-escalated CHOP (cyclophosphamide 1500 mg/m(2), doxorubicin 70 mg/m(2), vincristine 1.4 mg/m(2) and prednisolone 100 mg for 5 days) every 3 weeks. Lenograstim (glycosylated rHuG-CSF), at a dose of 2 micro g/kg/day s.c., was administered daily from day 3 until day 13 with biweekly CHOP and until day 20 with the dose-escalated CHOP. The primary endpoint was complete response rate. RESULTS The complete response rate was 60% [21 of 35; 95% confidence interval (CI) 42% to 76%] with biweekly CHOP and 51% (18 of 35; 95% CI 34% to 69%) with dose-escalated CHOP. The major toxicity was grade 4 neutropenia and was more frequent in the dose-escalated CHOP arm (86%) than in the biweekly CHOP arm (50%). Grade 4 thrombocytopenia was also more frequent in the dose-escalated CHOP arm (20%) than the biweekly CHOP arm (3%). Non-hematological toxicities were acceptable in both arms. One treatment-related death (due to cardiac arrhythmia) was observed in a dose-escalated CHOP patient. Progression-free survival at 3 years was 43% (95% CI 27% to 59%) in the biweekly CHOP arm and 31% (95% CI 16% to 47%) in the dose-escalated CHOP arm. Although seven patients were deemed ineligible by central review of the pathological diagnosis, the results for both eligible and all enrolled patients were similar. CONCLUSIONS Similar complete response rates and progression-free survival rates, but lower toxicity, indicated that biweekly CHOP was superior to dose-escalated CHOP in the treatment of aggressive NHL. Based on these results, the Lymphoma Study Group of the Japan Clinical Oncology Group is conducting a randomized phase III study comparing biweekly CHOP with standard CHOP in newly diagnosed patients with advanced-stage aggressive NHL.

Abstract
BACKGROUND The aim of the study was to determine factors affecting the toxicity and efficacy of rituximab monotherapy in relapsed patients with indolent B-cell lymphoma and mantle cell lymphoma (MCL). PATIENTS AND METHODS A total of 90 patients were enrolled and treated with rituximab infusions at 375 mg/m2 once weekly for 4 weeks. Central pathology review revealed that histologically, 81 patients had indolent B-cell lymphoma or MCL: 59 with follicular lymphoma, 17 with MCL, four with marginal zone lymphoma and one with lymphoplasmacytoid lymphoma. Of these, four were ineligible due to violation of other eligibility criteria. Pre-treatment variables affecting toxicities were analyzed for all 90 patients, and those affecting response and progression-free survival (PFS) were analyzed for 77 eligible patients with confirmed indolent B-cell lymphoma or MCL. The relationship between serum rituximab levels and efficacy was also analyzed for 66 eligible patients. RESULTS Hematological toxicities (grade > or =3) occurred more frequently in females (P <0.05), and thrombocytopenia and leukopenia were more frequent in patients with high lactate dehydrogenase (LDH) levels (P <0.05). Non-hematological toxicities (grade > or =2) were more frequent in patients with extranodal disease or bone marrow involvement. The overall response rate (ORR) in patients receiving one prior chemotherapy regimen was higher than those receiving two or more regimens (P <0.05). The median PFS was shorter in MCL patients, in those with extranodal disease, or in those receiving two or more prior chemotherapy regimens (P <0.01). The PFS intervals of patients with higher serum rituximab levels (> or =70 microg/ml) immediately before the third infusion were longer than in other patients (P <0.01). CONCLUSIONS Several prognostic factors and serum rituximab levels are useful for predicting the toxicity and efficacy of rituximab monotherapy.

Abstract
Fusions of the ETV6/TEL gene to receptor or protein tyrosine kinases (TKs), such as PDGFRbeta, JAK2, ABL, ABL2, TRKC, and Syk, have been reported in various hematological malignancies. Expression of the resultant chimeric proteins is believed to lead to constitutive TK activity through activation by the helix-loop-helix (HLH) domain of ETV6. We identified a novel ETV6 partner gene, fibroblast growth factor receptor 3 (FGFR3), in a patient with peripheral T-cell lymphoma (PTCL) with a t(4;12)(p16;p13) translocation. The ETV6-FGFR3 transcript showed a fusion of exon 5 of ETV6 to exon 10 of FGFR3, resulting in an open reading frame for a chimeric protein consisting of the HLH domain of ETV6 and the TK domains of FGFR3. This is the first report of ETV6 and FGFR3 involvement in PTCL.

Abstract
We applied the International Prognostic Scoring System (IPSS) to our series of 118 patients with myelodysplastic syndrome (MDS) to determine its validity, and also used univariate and multivariate analyses to evaluate the prognostic significance of TP53 configurations. Sixteen patients with the mutation had a strikingly worse prognosis and the multivariate analysis demonstrated that this alteration was the most significant factor. The prognostic comparison between patients with and without the mutation within each IPSS subgroup showed a significant difference in the intermediate subgroups. A combination of clinical manifestations and genetic configurations provided us with more accurate prognostic information in MDS patients.

Abstract
We describe a patient with acute lymphoblastic leukemia (ALL, L2) who relapsed with multiple bone lesions after allogeneic bone marrow transplantation (allo-BMT). Allo-BMT was performed from an HLA-identical sibling during the first hematological complete remission (CR). Minimal residual disease (MRD) assessed by polymerase chain reaction (PCR) with primers for T cell receptor delta (TCRdelta) gene became positive in the bone marrow sample on day 46 after allo-BMT. On day 113, the patient complained of a painful tumor at the right clavicle. The examination of biopsy specimen revealed infiltration of leukemic cells. After partial response was achieved by local radiotherapy, disseminated bone lesions were demonstrated by 99mTC scintigraphy scan, followed by bone marrow relapse on day 137. The patient died of cardiac tamponade on day 236 after Allo-BMT. MRD assessed by PCR assay for TCRdelta gene in the bone marrow is useful for the prediction of extramedullary as well as medullary relapse after BMT.

Abstract
Primary uterine non-Hodgkin's lymphoma (NHL) is an extremely rare disease. To accumulate more information on clinical data, we report three cases of primary uterine NHL with apparently the first demonstration of karyotypic analysis. Histological diagnosis was diffuse large B cell type in all patients. Two of them with advanced stage showed chemoresistance and a short survival. The remaining case with early stage showed an uneventful course following operation. No common chromosomal abnormality was detected. The therapeutic strategy for uterine NHL might therefore be similar to that for other types of aggressive NHL, although a larger study is needed.

Abstract
Gene alterations accumulate during the progression of acute myelogenous leukemia (AML) to a malignant clone. Here, a new myeloid cell line, designated YSK-21, with the balanced t(8;21)(q22;q22) and the unbalanced der(1)t(1;17)(p36;q21), was established. YSK-21 grows well in a medium containing recombinant human granulocyte colony-stimulating factor (rhG-CSF), granulocyte-macrophage colony-stimulating factor (rhGM-CSF), or interleukin-3 (rhIL-3). Molecular analysis using the reverse transcriptase-polymerase chain reaction (RT-PCR) and fluorescence in situ hybridization (FISH) revealed that t(8;21)(q22;q22) resulted in an AML1-MTG8 fusion transcript. FISH and spectral karyotyping (SKY) in conjunction with G-banding analysis revealed a der(1)t(1;17)(p36;q21) chromosomal translocation, which appeared in the clone developed from the original leukemic cells. Molecular analysis of the TP73 gene on 1p36 and the TP53 gene revealed a deletion of one-allele in TP73 with partial demethylation of another allele in the initial clone of YSK, and a point mutation consisting of an A-->T substitution in codon 288 of the TP53 gene in the developed clone of YSK-21. YSK-21 cells, expressing aberrant AML1-MTG8, TP53, and TP73 protein molecules, may be useful for elucidating the pathophysiology of these aberrant proteins and for studying the der(1)t(1;17)(p36;q21) chromosomal translocation.

Abstract
A 83-year-old woman was referred to our hospital because of swollen lymph nodes, marked splenomegaly, and bone marrow abnormality. Histological examination of the lymph nodes revealed characteristic findings for small lymphocytic lymphoma/chronic lymphocytic leukemia (SLL/CLL). The immunophenotype of the tumor cells was CD5+, 10-, 19+, 20+, 23-, IgM+D+. Interphase fluorescent in situ hybridization (FISH) detected t(11;14), and immunohistochemical studies demonstrated cyclin D1 expression. In both SLL/CLL and mantle cell lymphoma (MCL), the normal counterpart of the tumor cells is thought to be CD5-positive B1 cells. The present case may therefore have been borderline between SLL/CLL and MCL.

Abstract
Two new human myeloma cell lines were established from pleural effusion and bone marrow malignant cells derived from a single patient, who manifested hyperammonemia associated with multiple myeloma, and these were characterized. Both lines possess t(11;14)(q13;q32) and t(8;14)(q24;q32) reciprocal translocations and overexpress cyclin D1, but not c-myc. Human myeloma lines including these new lines produced and secreted excess ammonia into culture medium more than non-myelomatous hematological cell lines. In addition, these two lines were revealed to have high surface CD7 expression correlated with relatively high mRNA expression by MP-RT-PCR. Among 8 human myeloma lines, half of them revealed significant surface expression of CD7 and a positive correlation between expression levels of protein and message. CD7 message was also detected in surface negative lines. Consequently, there may be posttranslational regulation of the CD7 molecule, whose cellular biological role in expressing cells has not been elucidated.

Abstract
To detect immunoglobulin heavy chain (IGH) gene translocations with specific oncogene loci, we established an interphase cytogenetic approach using double-color fluorescence in situ hybridization (DC-FISH), which we used to analyze 173 patients with B-cell lymphoma. DC-FISH using the IGH gene (14q32.3) in combination with c-MYC (8q24.1), BCL1 (11q13.3), BCL2 (18q21.3), BCL6 (3q27), and PAX-5 (9p13) gene probes detected IGH translocations in 70 (40.5%) of 173 patients. The partner genes involved in IGH translocations were identified in 56 (80%) of 70 patients, and fusion of the IGH gene with specific oncogenes was detected in 53 of 56 patients, particularly in interphase nuclei of 28 patients for whom cytogenetic analysis was not informative. The most common partner gene was BCL2 (19 patients; 27% of IGH translocation-positive patients), followed by BCL6 (16; 23%), BCL1 (11; 16%), c-MYC (7; 10%), and PAX-5 (2; 3%). These oncogenes were closely associated with subtypes of B-cell lymphoma. The other partners were 19q13 (BCL3), 6p25 (MUM1/IRF4), 1q36, and chromosome 8 identified in one patient each. Six of the nine patients with add(14)(q32) showed a BCL6/IGH translocation. Double translocations of the IGH gene were found in three patients; c-MYC+BCL1, c-MYC+BCL2, and c-MYC+BCL6 in each one. Interphase FISH using specific IGH-translocation probes is valuable for defining clinically meaningful subgroups of B-cell lymphoma.
