Abstract
BACKGROUND BPaL, a 6 month oral regimen composed of bedaquiline, pretomanid, and linezolid for treating extensively drug-resistant tuberculosis (XDR-TB) is a potential alternative for at least 20 months of individualized treatment regimens (ITR). The ITR has low tolerability, treatment adherence, and success rates, and hence to limit patient burden, loss to follow-up and the emergence of resistance it is essential to implement new DR-TB regimens. The objective of this study was to assess the acceptability, feasibility, and likelihood of implementing BPaL in Indonesia, Kyrgyzstan, and Nigeria. METHODS We conducted a concurrent mixed-methods study among a cross-section of health care workers, programmatic and laboratory stakeholders between May 2018 and May 2019. We conducted semi-structured interviews and focus group discussions to assess perceptions on acceptability and feasibility of implementing BPaL. We determined the proportions of a recoded 3-point Likert scale (acceptable; neutral; unacceptable), as well as the overall likelihood of implementing BPaL (likely; neutral; unlikely) that participants graded per regimen, pre-defined aspect and country. We analysed the qualitative results using a deductive framework analysis. RESULTS In total 188 stakeholders participated in this study: 63 from Kyrgyzstan, 51 from Indonesia, and 74 from Nigeria The majority were health care workers (110). Overall, 88% (146/166) of the stakeholders would likely implement BPaL once available. Overall acceptability for BPaL was high, especially patient friendliness was often rated as acceptable (93%, 124/133). In contrast, patient friendliness of the ITR was rated as acceptable by 45%. Stakeholders appreciated that BPaL would reduce workload and financial burden on the health care system. However, several stakeholders expressed concerns regarding BPaL safety (monitoring), long-term efficacy, and national regulatory requirements regarding introduction of the regimen. Stakeholders stressed the importance of addressing current health systems constraints as well, especially in treatment and safety monitoring systems. CONCLUSIONS Acceptability and feasibility of the BPaL regimen is high among TB stakeholders in Indonesia, Kyrgyzstan, and Nigeria. The majority is willing to start using BPaL as the standard of care for eligible patients despite country-specific health system constraints.

Abstract
Protein glycation is a major biochemical event that takes place in the plasma of diabetic patients due to increased sugar levels. Extensive glycation leads to the formation of advanced glycation end products (AGEs) that is well known for having detrimental effects on diabetic patients. In the current work, we have glycated the physiologically important protein Haemoglobin A0 in vitro to study AGE formation and activity by using them as a template for gold nanoparticle (GNPs) synthesis. It was found that the surface plasmon resonance of synthesised GNPs showed high correlation with the extent of glycation. On fractionation, the glycated Haemoglobin A0 segregated into two distinct population of products, one consisting of proteinaceous, cross-linked larger fragments of Haemoglobin A0 and a second population of non-proteinaceous low molecular weight AGEs. Only low molecular weight AGEs contributed to synthesis of GNPs upon using the fractions as a template, substantiating the principle of proposed GNP-based assay. Owing to its physiological importance, AGEs can be used as a diagnostic means for diabetes and its associated complications. In this study, we have employed the high reactivity of AGEs for the development of a GNP-based novel colorimetric sensor to enable their detection. Our proposed GNP-based sensing could have high clinical significance in detecting diabetes and its associated complexities.

Abstract
Consider a circle with perimeter N > 1 on which k < N segments of length 1 are sampled in an independent and identically distributed manner. In this paper we study the probability π (k,N) that these k segments do not overlap; the density φ(·) of the position of the disks on the circle is arbitrary (that is, it is not necessarily assumed uniform). Two scaling regimes are considered. In the first we set k≡ a√N, and it turns out that the probability of interest converges (N→ ∞) to an explicitly given positive constant that reflects the impact of the density φ(·). In the other regime k scales as aN, and the nonoverlap probability decays essentially exponentially; we give the associated decay rate as the solution to a variational problem. Several additional ramifications are presented.

Abstract
INTRODUCTION Flow cytometry is the most sensitive and specific diagnostic modality for the assessment of clone size in paroxysmal nocturnal haemoglobinuria (PNH) and other bone marrow failure states. In this study, we attempt to distinguish PNH from aplastic anaemia (AA) and myelodysplastic syndromes (MDS) associated with PNH clones at diagnosis by clone size, clinical and laboratory features. METHODS A total of 29 samples included 19 PNH cases and 10 AA/MDS cases with PNH clones. Flow cytometry was performed using fluorescent aerolysin (FLAER)-based assay and comparison of clinical features, laboratory parameters and PNH clone size was carried out at diagnosis. RESULTS The PNH clone size on granulocytes varied from 0.4% to 99.2% and correlated with the clone size on monocytes (r = 0.966; P < 0.001). Paroxysmal nocturnal haemoglobinuria clone size on granulocytes (median = 34.6%) and monocytes (median = 49.9%) was always larger than erythrocytes (median = 10.9%). The median clone size in PNH (median granulocytes = 74.9%, monocytes = 71.8%) was significantly greater than in AA/MDS associated with PNH clone (median granulocytes = 2.9%, monocytes = 6%). In PNH patients, a significant negative correlation was seen between PNH clone on monocytes and the haemoglobin concentration. CONCLUSION In our small study using the FLAER method, the clone size was >70% in majority of PNH cases. In other marrow disorders like AA/MDS, the clone size was usually <10%.

Abstract
We randomly screened 363 yeast isolates during 2008 for their ability to form white colonies on CHROM agar Candida medium. Two of these isolates (0.5%) were identified as Candida nivariensis based on detailed phenotypic characterization and DNA sequencing. One was recovered from the sputum of an HIV-positive patient with a pneumonic lesion and the second from the blood of a diabetic with oropharyngeal lesions. Direct DNA sequencing of the D1/D2 region of 28S rRNA gene and/or the internal transcribed spacer (ITS) regions of rDNA confirmed that both of the isolates were C. nivariensis. The carbohydrate assimilation profiles with the ID 32 C and VITEK 2 yeast identification systems revealed only glucose assimilation. In vitro antifungal susceptibility profiles by broth microdilution and Etest methods revealed susceptibility of both isolates to fluconazole, itraconazole, voriconazole, amphotericin B and 5-flucytosine, with low MICs for posaconazole and caspofungin. These results document the occurrence of Candida nivariensis for the first time in India and focus on its potential as an opportunistic human pathogen.

Abstract
Myeloperoxidase (MPO) is an unequivocal marker of myeloid differentiation which is routinely detected using cytochemistry (CC), flow cytometry (FC) and immunohistochemistry (IH). Several studies have compared the use of two of these methods, but to our knowledge none has compared all three techniques. We compared the performance of these three modalities in the detection of MPO in 158 cases of acute myeloid leukaemia (AML). Discrepancies were noted in a total of 28 cases. Of 110 cases in which all three modalities were performed, 23 cases showed discrepancies. CC was the least sensitive marker, being negative in 11 of 23 cases in the presence of positive IH and/or FC. IH was the most sensitive marker with only one case being negative in the presence of a positive result by FC and/or CC. The results highlight the necessity of employing more than one method in determining the presence of MPO and confirm the important role of IH in the diagnosis of AML particularly in cases where MPO is not detected by CC and FC.

Abstract
The application of immunohistology to the spectrum of plasma cell disorders has yet to be incorporated widely into routine haematology practice. This technique enables the direct visualisation of specific surface and cytoplasmic antigens in the context of the individual cell and the surrounding anatomical neighbourhood. This review outlines the role of bone marrow immunohistology in the laboratory evaluation of patients with suspected and established plasma cell neoplasms and its emerging role in understanding myeloma biology for possible future therapeutic application.

Abstract
There have been few reports on the morphological findings in patients with chronic myeloid leukaemia (CML) undergoing treatment with imatinib mesylate. We examined morphological changes in the marrow and peripheral blood of 27 patients with chronic phase (CP), accelerated phase (AP) and blastic phase (BP) CML, 3 and 6 months after treatment with imatinib. At 3 months there was a significant clearance of leukaemic cells as evidenced by a complete haematological response (CHR) in the peripheral blood in 25 patients, together with reduced marrow cellularity in 25 (median reduction CP 42%; AP/BP 68%) and a reduction in the number of megakaryocytes (13 of 18 CP: five of six AP/BP; three patients did not have an assessable marrow) with an increase in the amount of normal megakaryopoiesis. After 6 months, there was continued morphological improvement in eight of 17 CP patients (one patient died after 3 months) with continued cytogenetic response (7 out of 15 patients with assessable metaphases had no abnormal Ph+ cells and three had <35% Ph+ cells) and maintenance of haematologic response in all patients. After an initial response to treatment at 3 months in the AP/BP group, with CHR and a reduction in cellularity in all patients, we found morphological evidence of a loss of response to treatment, with an increase in leukaemic cells, as evidenced by loss of CHR in three of nine and an increase in median cellularity in five patients. No patient in this group achieved a complete cytogenetic response. In summary, in CML-CP patients treated with 6 months of imatinib, there was a significant reduction in leukaemic cells as evidenced by a haematolological response in the peripheral blood, together with reduced marrow cellularity, restoration of morphologically normal haemopoiesis and a meaningful cytogenetic response. Maintaining a response to treatment appeared less likely to occur in the AP/BP group patients, especially those who did not achieve any cytogenetic response to treatment.

Abstract
Myeloproliferative disorders (MPD) are associated with an increased risk of thrombotic complications. We describe three patients with portal or hepatic vein thrombosis and normal peripheral blood counts who had MPD on bone marrow morphology and growth factor-independent megakaryocyte or erythroid colony growth in vitro. The peripheral blood counts have become abnormal subsequently in two patients. Patients presenting with unexplained portal or hepatic vein thrombosis should be investigated systematically for the presence of a MPD, which may not be apparent using conventional diagnostic criteria.

Abstract
We report a case of an atypical myeloproliferative disorder with t(8;13) that presented as B-lineage acute lymphoblastic leukaemia (B-ALL). Following induction chemotherapy, the disease manifested as chronic myeloproliferative state, which responded to hydroxyurea. Terminally, the disease transformed into acute myeloid leukaemia (AML) with additional chromosomal abnormalities including monosomy 7. To our knowledge, this is the first case of this rare atypical myeloproliferative disorder with t(8;13) that presented as B-ALL and terminally transformed to AML with additional chromosomal abnormalities.

Abstract
BACKGROUND High-dose therapy (HDT) with autologous bone marrow or blood cell transplantation for the treatment of lymphoma commenced at Peter MacCallum Cancer Institute in 1986. AIM To examine the patient characteristics and outcomes of patients with non-Hodgkin's lymphoma (NHL) and Hodgkin's disease (HD) treated with HDT and autologous transplantation at our Institute in the first 10 years of the service (1986-95). METHODS A retrospective analysis was performed examining patient characteristics, prior chemotherapy regimens, pretransplant disease status, HDT regimen, source of stem cells, time for haematopoietic recovery, complications of transplantation, response rates, overall survival (OS) and progression-free survival (PFS). RESULTS Sixty-seven patients with NHL were treated with an estimated 5-year OS rate of 44% (95% confidence interval (CI) 32-56%) and PFS rate of 34% (95% CI 21-44%). Factors independently predictive of an unfavourable PFS on multivariate analyses were presence of constitutional symptoms at transplant (P < 0.002) and chemotherapy-resistant disease at transplant (P = 0.02). Twenty-three patients with HD were treated with a 5-year predicted OS rate of 74% (95% CI 56-92%) and PFS rate of 57% (95% CI 36-77%). There was no difference in PFS for HD patients who relapsed either within 12 months of completion of front-line therapy or after this time (P= 0.5). The transplant-related mortality for the entire cohort was 17%, with a progressive decrease over time. CONCLUSION HDT with autologous transplantation achieves durable PFS and OS in patients with lymphoma. Improved patient selection, therapy modifications according to prognostic factors and ongoing improvements in supportive care should improve outcomes further.

Abstract
This phase I study was designed to determine the optimal dosages of a novel repetitive high-dose therapy regimen for patients with metastatic breast cancer (MBC). The planned treatment was three cycles of high-dose cyclophosphamide, thiotepa and docetaxel delivered every 35 days with progressive dose-escalation in successive cohorts. Each cycle was supported by peripheral blood progenitor cells (PBPC) and filgrastim. Eighteen patients were entered into this trial. Of the planned 54 treatment cycles, 44 were delivered and 11 patients completed all three cycles. The dose-limiting toxicities were interstitial pneumonitis and mucositis with moderately severe diarrhea (n = 3) and rash (n = 3). There were no treatment-related deaths. Of the 17 patients with evaluable disease, 16 patients responded with six patients achieving a complete remission and an additional four patients achieving no detectable disease (negative restaging including PET scan) but a persistently abnormal bone scan. At a median follow-up of 12 months, median progression-free survival was 11 months with the median overall survival not reached. The recommended doses for phase II/III studies are cyclophosphamide (4 g/m2), thiotepa (300 mg/m2) and docetaxel (100 mg/m2).

Abstract
We prospectively evaluated docetaxel (100 mg/m2) with G-CSF (10 microg/kg S.C., daily) for mobilization efficiency in 26 patients with breast cancer. The minimum target yield was >4.5 x 10(6) CD34+ cells/kg (optimum = 9 x 10(6)/kg), sufficient to support the subsequent three cycles of high-dose therapy (HDT). The peak days for peripheral blood (PB) CD34+ cells were day 8 and day 9. Seven collections began on day 7, 16 on day 8 and three on day 9. The median peripheral blood progenitor cell (PBPC) CD34+ cell content ranged from 1.2 to 5.9 x 10(6)/kg per day during days 7 to 11 with a median CD34+ content of the total 72 PBPC collections of 3.4 x 10(6)/kg (0.07-15.6). Fifteen patients obtained a PBPC collection exceeding 5 x 10(6)/kg on a single day of collection. Following a median 3 days collection for each patient (range 2-4), the median total CD34+ for all individual sets of collections was 9.7 x 10(6)/kg (range 1.0-28.4). We were able to achieve the minimum CD34+ cell target yield in 22 of 26 patients with one cycle of mobilisation chemotherapy and in two of these patients a second collection yielded sufficient cells. Twenty-two patients have subsequently received repetitive HDT and PBPC transplantation with 57 cycles of HDT having been delivered. For all 57 cycles, the median time to absolute neutrophil count (ANC) >0.5 x 10(9)/l and 1.0 x 10(9)/l was 10 days (range 8-22) and 11 days (range 8-23), respectively. The median time to platelets greater than 20 x 10(9)/l, 50 x 10(9)/l and 100 x 10(9)/l was 13 days (range 11-23), 17 days (range 12-53) and 23 days (range 18-70), respectively. We conclude that docetaxel with G-CSF effectively mobilises PBPCs with apheresis needing to be commenced approximately 8 days after docetaxel administration.

Abstract
To determine the safety and efficacy of the combination of idarubicin, cytarabine and etoposide ("ICE") for induction and consolidation treatment of acute myeloid leukemia (AML), and of dose-intensification of cytarabine in this setting, 54 previously untreated patients in three cohorts were studied by sequential dose escalation of cytarabine, in combination with standard doses of idarubicin and etoposide. Cytarabine was given to Cohort 1 at the conventional dosage of 100 mg/m2 per day by continuous infusion for 7 days in induction and 5 days in consolidation; to Cohort 2 at high-dose (HiDAC) (3 g/m2 intravenously twice daily on days 1, 3, 5 and 7) during induction with conventional dosage during consolidation; to Cohort 3 HiDAC was given for both induction and consolidation. In addition, Cohort 3 patients received lenograstim (Granocyte; rHuG-CSF) after both induction and consolidation courses. We found that there was no significant difference between the three cohorts in hematological toxicity in induction, but that HiDAC was associated with a greater incidence of gastro-intestinal toxicities. There was no difference in induction mortality between the three cohorts, which was 11% overall. Consolidation with HiDAC led to a significant increase in hematological toxicity. Overall, the complete remission (CR) rate was 80% with no significant difference between the three regimens. The estimated disease free survival at 3 years was 28%, 67% and 54% respectively for Cohorts 1, 2 and 3 with an estimated overall survival of 38%, 63% and 47%. We conclude that cytarabine dosage can be escalated safely in combination with idarubicin and etoposide in both induction and consolidation. The combination is effective for induction treatment of AML and its side-effects appear similar to those of standard regimens. Whether its use offers long-term benefits compared with standard regimens is the subject of ongoing controlled randomized studies.

Abstract
The expression of P-glycoprotein (Pgp) is often increased in acute myeloid leukemia (AML). However, little is known of the regulation of Pgp expression by cytotoxics in AML. We examined whether Pgp expression and function in leukemic blasts was altered after a short exposure to cytotoxics. Blasts were isolated from 19 patients with AML (15 patients) or chronic myeloid leukemia in blastic transformation (BT-CML, 4 patients). Pgp expression and function were analyzed by flow cytometric analysis of MRK 16 binding and Rhodamine 123 retention, respectively. At equitoxic concentrations, ex vivo exposure for 16 hours to the anthracyclines epirubicin (EPI), daunomycin (DAU), idarubicin (IDA), or MX2 or the nucleoside analogue cytosine arabinoside (AraC) differentially upregulated MDR1/Pgp expression in Pgp-negative and Pgp-positive blast cells. In Pgp-negative blasts, all four anthracyclines and AraC significantly increased Pgp expression (P =.01) and Pgp function (P =.03). In contrast, MX2, DAU, and AraC were the most potent in inducing Pgp expression and function in Pgp positive blasts (P <.05). A good correlation between increased Pgp expression and function was observed in Pgp-negative (r =.90, P =.0001) and Pgp-positive blasts (r =.77, P =.0002). This increase in Pgp expression and function was inhibited by the addition of 1 micromol/L PSC 833 to blast cells at the time of their exposure to these cytotoxics. In 1 patient with AML, an increase in Pgp levels was observed in vivo at 4 and 16 hours after the administration of standard chemotherapy with DAU/AraC. Upregulation of Pgp expression was also demonstrated ex vivo in blasts harvested from this patient before the commencement of treatment. In 3 other cases (1 patient with AML and 2 with BT-CML) in which blasts were Pgp negative at the time of initial clinical presentation, serial samples at 1 to 5 months after chemotherapy showed the presence of Pgp-positive blasts. All 3 patients had refractory disease. Interestingly, in all 3 cases, upregulation of Pgp by cytotoxics was demonstrated ex vivo in blasts harvested at the time of presentation. These data suggest that upregulation of the MDR1 gene may represent a normal response of leukemic cells to cytotoxic stress and may contribute to clinical drug resistance.

Abstract
For patients with metastatic breast cancer (MBC) who undergo high-dose therapy with autologous peripheral blood progenitor cell (PBPC) transplantation, an important prerequisite is a mobilization regimen that efficiently mobilizes PBPCs while producing an effective anti-tumor effect. We prospectively evaluated ifosfamide-based chemotherapy for mobilization efficiency, toxicity and disease response in 37 patients. Patients received two cycles of the ifosfamide-based regimen; ifosfamide (5 g/m2 with conventional-dose cycle and 6 g/m2 with mobilization cycle) with either 50 mg/m2 doxorubicin (if limited prior anthracycline and/or progression more than 12 months after an anthracycline-based regimen) or 175 mg/m2 paclitaxel. For the mobilization cycle, all patients received additional G-CSF (10 microg/kg SC, daily) commencing 24 h after completion of chemotherapy. The target yield was >6x10(6) CD34+ cells/kg, sufficient to support the subsequent three cycles of high-dose therapy. The mobilization therapy was well tolerated and the peak days for peripheral blood (PB) CD34+ cells were days 10-13 with no significant differences in the PB CD34+ cells mobilization kinetics between the ifosfamide-doxorubicin vs. ifosfamide-paclitaxel regimens. The median PBPC CD34+ cell content ranged from 2.9 to 4.0x10(6)/kg per day during days 9-14. After a median of 3 (range 1-5) collection days, the median total CD34+ cell, CFU-GM and MNC for all 44 individual sets of collections was 9.2x10(6)/kg (range 0.16-54.9), 37x10(4)/kg (range 5.7-247) and 7.3x10(8)/kg (range 2.1-26.1), respectively. The PBPC target yield was achieved in 35 of the 37 patients. The overall response rate for the 31 evaluable patients was 68% with 10% having progressive disease. Thirty-three patients have subsequently received high-dose therapy consisting of three planned cycles of high-dose ifosfamide, thiotepa and paclitaxel with each cycle supported with PBPCs. Rapid neutrophil and platelet recovery has been observed. Ifosfamide with G-CSF in combination with doxorubicin or paclitaxel achieves effective mobilization of PBPC and anti-tumor activity with minimal toxicity.

Abstract
A reliable measure to predict peripheral blood progenitor cell (PBPC) autograft CD34+ cell content is required to optimize the timing of PBPC collection. We prospectively examined the peripheral blood (PB) CD34+ cell count in 59 consecutive patients with various malignancies and analyzed the correlation between the PB CD34+ cell count and various parameters in the PBPC autograft. Two hundred and thirty-five collections were performed with a median of 4.0 collections per patient (range, 2-10). The median PB CD34+ cell count at the time of collection was 39 x 10(6)/1 (range, 0.0-285.6). The PBPC autograft parameters measured were the CD34+ cell, colony-forming unit granulocyte-macrophage (CFU-GM) and mononuclear cell (MNC) content. There was a strong linear correlation between PB CD34+ cells/l and autograft CD34+ cells/kg (r = 0.8477). The correlation with CFU-GM/kg (r = 0.5512) was weaker. There was no correlation between autograft CD34+ cells/kg and PB WBC (r= 0.0684), PB MNC (r = 0.1518) or PB platelet count (r = 0.2010). At our institution we aim to obtain a minimum of 0.5 x 10(6) CD34+ cells/kg with each day of collection. We demonstrate that such a collection can be reliably obtained if the PB CD34+ cell count exceeds 5.0 x 10(6)/l.

Abstract
The erythrocyte sedimentation rate (ESR), liver alkaline phosphatase (ALP), serum copper (Cu) and urinary nucleoside excretion (UNs) have been proposed as independent prognostic markers in Hodgkin's Disease (HD). However, their prognostic value has not satisfactorily been directly compared to recognised clinical prognostic factors. One hundred and sixty-eight patients with HD had the above markers performed prior to initial treatment. At a median follow-up of 10.9 yrs, the predicted 10 year relapse free survival (RFS) and overall survival (OS) for the entire cohort is 64% and 66%, respectively. In general, patients with elevated markers were significantly less likely to achieve CR, remain in CR and survive. However, multivariate analysis revealed this was due to the association of elevated markers with stage and constitutional symptoms. Following therapy, elevated markers were also correlated with evidence of clinically detectable disease. We conclude that although UNs, Cu, ALP and ESR reflect disease activity, they do not provide independent information beyond that of clinical assessment.

Abstract
Some cases of hypereosinophilic syndrome and myeloproliferative disorders exhibit common features and thus pose diagnostic and therapeutic problems. We describe a 68-year-old patient who presented with such features and developed lytic lesion in the tibia. Based on our case and a review of literature we suggest that cases like ours should be classified and treated as chronic eosinophilic leukemia (a myeloproliferative disorder) rather than as a hypereosinophilic syndrome or as an atypical chronic myeloid leukemia.

Abstract
In this study cytogenetic findings have been correlated with prognosis in 78 previously untreated patients with non-Hodgkin's lymphoma (NHL) presenting between 1983 and 1988. The median follow-up was 7 years (range 2-9 years). There was no significant difference in the duration of survival of 33 patients with only abnormal karyotypes, 35 patients with a mixture of normal and abnormal karyotypes (AN) and 10 patients with only normal karyotypes (NN). This was true for the entire group (p = 0.6) as well as for the subsets of diffuse lymphomas (DL) and follicular lymphomas (FL) (p = 0.6 and 0.4, respectively). Monosomy 14 was the only abnormality in the entire group of patients to be associated with a statistically significant difference in survival duration (p = 0.046). Among the FL patients, trisomy 7 (p = 0.046) and trisomy 12 (p = 0.010) were associated with shorter survival. Presence of t(14;18) did not influence survival in the entire group (p = 0.16), nor in any of the histological subgroups. Among the FL patients with t(14;18), presence of additional cytogenetic abnormalities was not associated with a worse outcome. The lack of consistency of results between various studies is likely to be due to several factors and the prognostic significance of karyotypic abnormalities can only be clarified by large prospective studies employing uniform treatment policies.

Abstract
High-dose cytarabine (ara-c) may overcome cytarabine resistance in leukemic blasts. It has been used as a successful salvage and in postremission therapy but not as initial induction treatment. Patients aged 15 to 60 years, presenting with newly diagnosed acute myeloid leukemia (AML) were randomized to receive either high-dose cytarabine, 3 g/m2 12 hourly on days 1, 3, 5, and 7 for 8 doses, daunorubicin 50 mg/m2 days 1 to 3, etoposide 75 mg/m2 days 1 to 7, (HIDAC-3-7) or standard dose cytarabine 100 mg/m2 continuous intravenous infusion for 7 days with daunorubicin and etoposide at the same dose and schedule as above (7-3-7). Patients could receive a second or third induction course if complete remission (CR) was not achieved. All patients received the same postinduction consolidation therapy (5-2-5) for 2 courses. Eligible patients had no prior chemotherapy or myelodysplastic disease. Patients have been followed for a median of 4.5 years. Of 301 patients treated, complete response (CR) was achieved in 71% with HIDAC-3-7 and 74% with 7-3-7. For patients in CR, the estimated median remission duration was 45 months with HIDAC-3-7 and 12 months with 7-3-7 (P = .0005 univariate analysis, P = .0004 multivariate analysis). The estimated percentage of patients relapse free 5 years after achieving a CR was 49% on HIDAC-3-7 and 24% on 7-3-7. Patients in CR tended to survive longer with HIDAC-3-7 but there were no overall survival differences between the two arms. HIDAC-3-7 was associated with significantly more toxicity in induction with more leukopenia, thrombocytopenia, nausea, and vomiting and eye toxicity (all P < .001) but a similar incidence of severe central nervous system and cerebellar toxicity compared to 7-3-7. The consolidation treatment was the same in both arms but caused significantly more leukopenia and thrombocytopenia in patients previously treated with HIDAC-3-7 induction (P < .0001). We conclude that a dose-effect exists for cytarabine in AML and that HIDAC-3-7 prolongs remission duration and disease-free survival and is tolerable when used as initial induction therapy in patients with de novo AML.

Abstract
We describe post-splenectomy lymphocytosis (PSL) in 23 patients, a majority (20/23) of whom have undergone splenectomy as a staging procedure for Hodgkin's disease. The absolute lymphocyte count ranged from 4.0 to 8.7 x 10(9)/l. The lymphocytosis was noted 4-242 (median 70) months after splenectomy and persisted almost unchanged in most patients on prolonged follow up (median 50 months). Immunophenotyping of the lymphocytes revealed no monoclonal B cell population.

Abstract
Cytogenetic studies of non-Hodgkin's lymphomas (NHL) have revealed a nonrandom translocation, t(14;18)(q32;q21), to be strongly correlated with follicular histology. In our recent study of 149 cases of NHL, 68 cases had a t(14;18). Forty-four of these were follicular and 24 diffuse. In the majority of cases (90%) there were additional chromosome abnormalities, which were analyzed to determine whether any were specifically associated with diffuse histology. Chromosome 11 abnormalities occurring together with the t(14;18) were found to be present in 17/68 cases; 14/17 (82%) were diffuse and 3/17 (18%) were follicular NHL. Thus, 14/24 (58%) of all diffuse lymphomas with t(14;18) had an abnormality of chromosome 11 compared to only 3/44 (7%) of follicular lymphomas, suggesting that the addition of an abnormality of chromosome 11 to a t(14;18) karyotype is associated with diffuse histology.

Abstract
We report two cases of secondary myelodysplastic syndrome (SMDS) which followed successful treatment of a primary malignancy with high-dose chemotherapy supported by reinfusion of autologous stem cells. The SMDS was diagnosed 24 months and 40 months, respectively, following autografting. Both patients lived for 7 months after the diagnosis of SMDS. Our cases support the view that there is an increased risk of SMDS/acute leukemia following autologous marrow transplantation.

Abstract
This study was designed to investigate the changes in the murine bone marrow microvasculature following treatment with 5-fluorouracil (5-FU) or total-body irradiation (TBI). Seventy 8- to 12-week-old C3H male mice received either 5-FU at a dose of 150 mg/kg intravenously (i.v.) or TBI at a dose of 8 Gy in two fractions 4 hours apart. Femurs from the treated mice were studied by vascular casting, using mercox, and by routine histology at days 5, 21, and 90. On day 5, the sinusoids were markedly swollen, and many were fused with one another. This was accompanied by significant reduction in the bone marrow cellularity. The central sinus was grossly dilated in both TBI- and 5-FU-treated groups. The pronounced sinusoidal dilatation on day 5 appears to be a mechanical effect due to hematopoietic cell loss resulting in relative negative pressure outside the sinusoids. On day 21, the sinusoidal swelling had subsided, and the overall vascular volume appeared to be restored to normal. However, there was a large variation in the shape and size of the sinusoids, and those present were not uniformly distributed. This may be due to the result of mechanical pressure from the reconstituted hematopoietic cells. Whether these changes in the shape and distribution of sinusoids have functional significance--for instance, release of the hematopoietic cells into the circulation--remains to be established.

Abstract
The prognostic value of immunophenotyping lymphomas with a panel of monoclonal antibodies (Mab) to various lymphoid antigens was assessed by studying 47 cases of diffuse large cell lymphoma. Cell suspensions were analysed by flow cytometry after labelling by indirect immunofluorescence. Thirty-eight cases were demonstrated to be of B cell and nine of T cell phenotype. Univariate analysis demonstrated that survival was significantly longer in patients expressing higher levels of HLA-DR (p = 0.01) and normal levels of CD8 (p = 0.04) but was not significantly associated with any of the other antigens. Our results support the possible value of HLA-DR in determining the prognosis of patients with diffuse large cell lymphoma.

Abstract
OBJECTIVE To present a case of adult T cell leukaemia lymphoma (ATLL) in a non-Aboriginal Australian woman with no apparent risk factor. CLINICAL FEATURES A 43-year-old Australian woman of European descent presented with a febrile illness associated with generalised lymphadenopathy and splenomegaly. INVESTIGATIONS There was lymphocytosis in the peripheral blood with a T helper cell phenotype. There were also lytic bone lesions with associated hypercalcaemia. HTLV-1 antibody was detected by agglutination assay and confirmed by western blot test. TREATMENT AND OUTCOME After initial response to CHOP chemotherapy (cyclophosphamide, doxorubicin, vincristine, prednisolone), she relapsed and died with central nervous system involvement eight months after the initial diagnosis. CONCLUSION To our knowledge this is only the third case of ATLL in a non-Aboriginal person in Australia.

Abstract
A peripheral blood smear from a patient with probable splenic lymphoma with villous lymphocytes (SLVL) showed clumping of lymphoma cells. The clumping was not seen in films made from unanticoagulated blood, and has not been previously described in lymphomas. The patient also had metastatic prostatic adenocarcinoma for 30 months before lymphoma was diagnosed and the clumped cells posed diagnostic problems.

Abstract
Sulfolipid-immobilizing protein 1 (SLIP1) is a germ cell plasma membrane protein that binds specifically to sulfogalactosylglycerolipid, a sulfoglycolipid found preferentially in mammalian male germ cells (Lingwood, Can. J. Biochem. Cell. Biol. 63:1077-1085, 1985b). SLIP1 in mouse and rat sperm exists on the periacrosomal membrane, where sperm initially bind to eggs. Using the in vitro mouse sperm-egg binding assay with in vitro-capacitated sperm, we obtained results previously suggesting that sperm SLIP1 is involved in mouse sperm-zona pellucida interaction. In this study, using the in vitro sperm-egg binding assay, we showed that SLIP1 in uterine sperm was similarly engaged in this process. Involvement of mouse sperm SLIP1 was also shown to be important in the in vivo fertilization process. Superovulated females inseminated with caudal epidididymal and vas deferens sperm preexposed to anti-SLIP1 IgG yielded only 20% fertilized zygotes, while 80% fertilization was observed in females inseminated with sperm preincubated with preimmune serum IgG. The lower fertilization rate was not due to changes in the sperm capacitation rate as assessed by chlortetracycline staining.

Abstract
A prospective cytogenetic study of patients with non-Hodgkin's lymphoma (NHL) presenting to one institution was commenced in 1983 as part of a larger study including histology, immunophenotyping, cytokinetics and survival. 175 patients were studied over 5 years and G-banded karyotypes were successfully obtained in 147. Chromosome abnormalities were detected in 135 cases (92%) with the commonest abnormality being t(14;18)(q32;q21) in 69 cases. Other non-random translocations were much less frequent, i.e. t(11;14) in seven cases and t(8;14) in four cases. Other specific structural changes included partial deletions of 6q (breakpoints ranging within q13-q23), 3q (breakpoints ranging within q21-q27), 1q and 10q22. Chromosome regions highlighted as being frequently involved in structural abnormalities were 11q13-q25, 1p22-p36, 3q21-q27 and 6q13-q23. Several specific recurring breakpoints were identified and these included 14q32, 18q21, 1p36 and 6q21. Frequently occurring numerical abnormalities were gains of chromosomes 3, 7, X and 12. Correlation with histological type showed, as expected, that t(14;18) was present in 89% of follicular lymphoma but also occurred in 30% of diffuse lymphoma. Abnormalities of 11q were correlated with the diffuse histologies as a group, whereas both numerical and structural abnormalities of chromosome 3 correlated with the diffuse large cell lymphoma (DLCL) subtype, and t(11;14) with diffuse small cleaved cell lymphoma (DSCCL). Although not statistically significant, abnormalities of 6q occurred twice as frequently in DLCL than in any other variety. However, several other commonly occurring abnormalities, such as extra copies of chromosomes 7, X, 12 and most of the structural abnormalities of 1p, did not correlate with any histological type. Therefore this large cytogenetic study has confirmed some previously reported correlations between specific chromosome abnormalities and histological subtypes of non-Hodgkin's lymphoma and has also identified some new correlations which may prove useful in the investigation of the biological basis of the disease.

Abstract
The examination of sequential karyotypes in hematologic disorders has demonstrated that karyotypic changes are often associated with concurrent changes in clinical behavior. Acquired abnormalities that recur among different patients may also suggest genomic areas important to tumor progression. We therefore examined sequential karyotypes in 21 patients with non-Hodgkin lymphoma (NHL). Sixteen of the 21 karyotypes demonstrated changes, including the majority of 6 small lymphocytic, 11 follicular, and 4 intermediate and high-grade diffuse lymphomas. The t(14;18)(q32;q21) occurred in ten initial karyotypes was retained in all cases. The band most frequently affected by newly acquired abnormalities was 14q32 (n = 5); chromosomes 1 and 2 (n = 5, each), and the 17p arm (n = 4) were also commonly affected. The acquired deletion of all or part of 17p appeared to be associated with a poor prognosis. Histologic transformation and karyotypic change did not correlate. This study of sequential karyotypes in NHL 1) confirms the primary importance of the t(14;18), 2) suggests that the 14q32 band is involved frequently in both primary and secondary cytogenetic events, and 3) suggests other genomic regions of potential significance to progression.
