Abstract
Acute myeloid leukaemia (AML) is an uncommon, rapidly progressive neoplasm in dogs. The aim of this retrospective study was to characterize the clinical presentation, haematologic findings, diagnostic imaging results, treatment and survival time of a contemporary cohort of dogs with AML. Diagnosis was based on >20% blasts in bone marrow or blood identified as myeloid based on morphologic findings, flow cytometric immunophenotyping and cytochemical staining. Medical records of 35 dogs diagnosed with AML from 2007 to 2015 were included. Most dogs presented with inappetence (66%) and lethargy (57%) and physical examination findings of peripheral lymphadenopathy (74%) and tachypnea (62%). Common haematologic findings were quantifiable circulating blasts (85%; median blast count 35 700/μL; range: 300-276 500/μL), anaemia (median haematocrit 34%; range: 11%-52%) and thrombocytopenia (median 57 000/μL; range: 9000-252 000/μL). Bicytopenia and pancytopenia were each found in 44% of dogs. Follow-up information was available for 34 dogs. The overall median survival time from diagnosis was 19 days (range: 1-121 days). Clinical progression in some dogs was not as rapid as previously reported. Haematologic responses to various chemotherapeutics were documented in 3 dogs, with associated survival times of 62, 103 and 121 days. Dogs treated with prednisone or a combination of chemotherapy and prednisone had improved survival compared to dogs that received symptomatic care only (P < .0001). Our results show canine AML has an overlapping clinical presentation with lymphoma. The prognosis for canine AML remains extremely guarded. Further studies are needed to optimize therapeutic regimens for dogs with AML.

Abstract
The prognosis of acute myelogenous leukemia (AML) in the elderly patients is extremely poor. Although several previous studies have suggested that intensive chemotherapy is associated with a better prognosis, there may have been a selection bias. Therefore, we retrospectively evaluated the impact of intensive chemotherapy for AML in the elderly by stratifying patients according to a propensity score. Eighty-one AML patients aged 70 years or more were included in this study. Patients with acute promyelocytic leukemia were not included. A propensity score for the use of intensive chemotherapy was calculated from four factors at diagnosis. Forty-five patients received intensive chemotherapy, whereas 36 received low-dose or no chemotherapy. We stratified the patients into quartiles based on the propensity score. The numbers of patients in the first, second, third, and forth quartiles who received intensive chemotherapy were 5 of 21, 10 of 20, 12 of 20, and 18 of 20, respectively. A stratified log-rank test showed significantly better overall survival in the intensive chemotherapy group (P = 0.0088). Especially, in the combined second and third quartiles, which showed an equal tendency for intensive and non-intensive strategies; overall survival at 3 years was 37.5 % for the intensive chemotherapy group and 13.0 % for the non-intensive chemotherapy group (P = 0.0022). A conventional multivariate analysis confirmed that intensive chemotherapy was beneficial (hazard ratio 0.50, 95 % confidence interval 0.27-0.93, P = 0.028). In conclusion, intensive chemotherapy may prolong overall survival in elderly AML patients who are considered to be able to tolerate such treatment based on factors at diagnosis.

Abstract
INTRODUCTION Hematological malignancies are quite common and affect all ages and genders. The diagnosis involves a multiparameter approach. The geographical distribution of various types of hematological malignancies has been provided by various authors but no such data have been published regarding the State of Uttarakhand in India. AIM To study the hematological malignancies at Uttarakhand in India based on age, sex and the type of malignancy with further sub typing wherever possible. SETTINGS AND DESIGN A total of 220 cases of hematological malignancies were worked up from the Reference Laboratory of Himalayan Institute of Medical Sciences over an eight year period (1998-2005). MATERIALS AND METHODS Diagnosis was mainly based on morphological examination of peripheral blood and bone marrow smears stained by Leishman's stain and MPO, Sudan Black and PAS stain as and where required. Distribution of cases was studied based on age, sex and the type of malignancy with further sub typing wherever possible. RESULTS The most common hematological malignancy was found to be Leukemia 129/220 (58%) followed b Lymphoma 33/220 (14.8%), Multiple Myeloma 55/220 (24.7%) and Metastatic Lesions 3/220 (1.3%). These malignancies were seen to be distributed throughout all ages with a peak at 11-20 years age group 39/220 (17.5%) and another peak at 51-60 years age group 41/220 (18.4%). We found an overall male preponderance with a M:F ratio of 2.3:1. CONCLUSIONS The commonest haematological malignancy in our series was Leukemia. Other diagnoses were Multiple Myeloma, Lymphoma and Secondaries. Multiple Myeloma which turned out to be the second most common diagnosis was an unusual finding.

Abstract
Acute myeloid leukaemia in the elderly is a disease with distinct biological properties, commonly associated with leukaemic cell treatment resistance and with an increased number of high-risk features, including concomitant myelodysplasia and poor-risk cytogenetic abnormalities such as monosomy 5 and 7. Complete remission rates after standard induction chemotherapy in patients above age 60 years are less than 50%, with long-term survival rates below 10%. Post-remission stem cell transplant therapies have not been studied extensively. Autologous transplants can result in an acceptable 3-year leukaemia-free survival rate of up to 47%, yet this procedure is applicable only to a small minority of patients. Myeloablative allogeneic transplants similarly show feasibility in selected few patients and in general are very toxic. Non-myeloablative allogeneic transplants are associated with reduced toxicity, but are plagued by an increased relapse rate. The latter strategy appears promising, but must be validated in larger, multi-centre prospective trials, in which outcomes are compared to non-transplant approaches.

Abstract
In this trial, acute myeloid leukemia patients (pts) aged 61-80 years received MICE (mitoxantrone, etoposide and cytarabine) induction chemotherapy in combination with different schedules of granulocyte colony-stimulating factor administration. Pts in complete remission were subsequently randomized for two cycles of consolidation therapy: mini-ICE regimen (idarubicin, etoposide and cytarabine) given according to either an intravenous (i.v.) or a 'non-infusional' schedule. Among the 346 pts randomized for the second step, 331 pts received consolidation-1 and 182 consolidation-2. A total of 290 events (255 relapses, 35 deaths in first CR) have been reported. The median follow-up was 4.4 years. No significant differences were detected in terms of disease-free survival (median 9 vs 10.4 months, P=0.15, hazard ratio (HR) =1.18, 95% confidence interval (CI) 0.94-1.49) - primary end point - and survival (median 15.7 vs 17.8 months, P=0.19, HR=1.17, 95% CI 0.92-1.50). In the 'non-infusional' arm grade 3-4 vomiting (10 vs 2%; P=0.001) and diarrhea (10 vs 4%; P=0.03) were higher than in the 'i.v.' arm, whereas time to platelet recovery >20 x 10(9)/l (median: 19 vs 23 days; P=0.02) and duration of hospitalization (mean: 15 vs 27 days; P<0.0001) was shorter. The 'non-infusional' consolidation regimen resulted in an antileukemic effect similar to the intravenous regimen, which was less myelosuppressive and associated with less hospitalization days.

Abstract
PURPOSE Chronic myelogenous leukemia (CML) is a disease characterized cytogenetically by the presence of the Philadelphia chromosome. Recent studies suggested that altered PDCD5 expression may have significant implications in CML progression. The aim of this study was to identify single-nucleotide polymorphisms (SNP) within the programmed cell death 5 (PDCD5) promoter region and show their functional relevance to PDCD5 expression as well as their genetic susceptibility to CML. EXPERIMENTAL DESIGN One hundred twenty-nine CML subjects and 211 healthy controls were recruited for identification of SNPs and subsequent genetic analysis. Luciferase reporter assays were carried out to show the functional significance of the SNPs located in the promoter region to PDCD5 expression. Real-time quantitative PCR and Western blot analysis were done to determine the expression differences of PDCD5 in CML patients with different genotypes. RESULTS Two SNPs were identified within the PDCD5 promoter. They are -27A>G and -11G>A (transcription start site as position 1), respectively. The complete linkage disequilibrium was found between these two polymorphisms. The frequencies of -27G+/-11A+ genotype and -27G/-11A allele were significantly higher in CML patients than in healthy controls (genotype: 26.36% versus 11.85%, chi2=11.75, P<0.01; allele: 13.57% versus 6.40%, chi2=9.48, P<0.01). Luciferase reporter assays revealed that the promoter with -27G/-11A had significantly lower transcriptional activity and could not be up-regulated after apoptotic stimulations compared with the promoter with -27A/-11G. PDCD5 expression analysis in mononuclear cells derived from CML patients and cell lines with different -27/-11 genotypes showed consistent results with the reporter assays. CONCLUSIONS These data suggest that -27G/-11A is associated with reduced PDCD5 promoter activity and increased susceptibility to CML.

Abstract
PURPOSE Little is known about the actual management and treatment of chronic myeloid leukemia (CML) in clinical practice, although there have been many recent changes, such as the introduction of imatinib. PATIENTS AND METHODS A two-phase cross-sectional observational study with retrospective data collection was conducted in France. In the first phase information regarding health services treating patients with CML was collected. In the second phase, centers caring for 10 or more patients were asked to provide data regarding patients diagnosed with CML that had had a consultation or been hospitalized in the last 3 months. RESULTS All French departments of hematology (n=218) were contacted by phone. The median number of patients followed per center is 6 (range 0--200). The median number of new patients seen during the last 12 months was 2 (range 0--60). In the second phase 538 patients were included, the sex ratio being 1.14 and median age 55. At the time of diagnosis, 96.8% (n=519) were in chronic phase, 2.2% (n=12) in accelerated phase and 0.9% (n=5) in blastic phase. Eighty-two percent (n=443) of the patients have been treated by interferon (IFN). Sixteen point 3% (n=87) of the patients received a bone marrow transplantation (BMT). Forty-six percent (n=236) of the patients were treated with imatinib. CONCLUSIONS This is the first study providing detailed descriptive data concerning the use of medications and procedures in a large population of patients from the medical centers involved in treating CML patients in France. Further observational studies are needed to assess the impact of different treatment strategies and economic impact of CML care in France.

Abstract
Chronic myeloid leukemia (CML) in older patients has not been studied well. To assess the long-term outcome of older patients with Philadelphia- and/or BCR-ABL-positive CML, 199 patients aged >/=60 years representing 23% of 856 patients enrolled in the German randomized CML-studies I (interferon alpha (IFN) vs hydroxyurea (HU) vs busulfan (BU) and II (IFN+HU vs HU alone) were analyzed after a median observation time of 7 years. In all, 45 patients were treated with Bu, 63 with HU, and 91 with IFN. The 5-year survival was 38% in patients >/=60 years and 47% in patients <60 years (P<0.001). Whereas 5-year survival in chemotherapy-treated older patients was inferior to that in younger patients (33 vs 46%, P=0.006 for HU and 29 vs 38%, P=0.042 for Bu), no significant survival difference could be verified in IFN-treated patients (46 vs 53%, P=0.077). Calculation of age-adjusted, relative survival confirmed these results. Adverse effects of IFN were similar in both age groups, but IFN dosage to achieve treatment goals was lower in older patients. We conclude that the course of CML is not different in the elderly. They require lower IFN doses, achieve the same hematologic and cytogenetic response rates and the same survival advantage at comparable toxicity.

Abstract
Although allogeneic transplantation is a curative therapy for chronic myelogenous leukemia (CML), treatment-related mortality is still a major cause of death after transplantation, especially in older patients. We investigated the safety and efficacy of reduced-intensity conditioning consisting of low-dose (600 cGy) total body irradiation and cytosine arabinoside (1 g/m2) together with a continuous infusion of granulocyte colony-stimulating factor and cyclophosphamide (120 mg/kg) in patients with CML in the chronic phase. Fractionated splenic irradiation (5 Gy) was also administered as part of the conditioning treatment. Eight patients older than 40 years underwent allogeneic bone marrow transplantation from an HLA-matched sibling following this conditioning. Regimen-related toxicities (equal to or greater than grade III) were not observed. Rapid restoration of 100% donor chimerism was confirmed by fluorescence in situ hybridization methods in 5 sex-mismatched transplant recipients. One patient died from severe acute graft-versus-host disease and another from Pneumocystis carinii pneumonia early in the course of transplantation. A sustained engraftment was achieved in 5 long-term survivors; in 1 case, the graft was rejected but the Philadelphia chromosome and BCR/ABL-negative autologous hemopoiesis were restored. After a minimum follow-up period of 60 months, 6 patients, including the patient with restored autologous hemopoiesis, were still alive and in remission with 100% donor chimerism. Six years after the transplantation, 1 patient experienced a cytogenetic relapse, which was successfully treated with donor lymphocyte infusions. In summary, this reduced-intensity conditioning resulted in a cure with markedly reduced regimen-related toxicities in this relatively older cohort of patients with CML.

Abstract
Although allogeneic transplantation is a curative therapy for chronic myeloid leukemia (CML), treatment-related mortality is still a major cause of posttransplantation mortality, especially for patients older than 40 years. We investigated, in a phase II trial, the role of a low-dose (550 cGy) high-dose rate (35 cGy/min) single-exposure total body irradiation (TBI) conditioning regimen for allogeneic peripheral blood stem cell (PBSC) transplantation in patients with CML. Between June 1997 and August 2000, 30 adult patients with CML underwent cytokine-mobilized allogeneic PBSC transplantation from HLA-matched siblings following administration of cyclophosphamide (60 mg/kg per day intravenously on days -2 and -1) and single-dose TBI (550 cGy delivered at 30 cGy/min on day 0). Cyclosporine A alone was administered for prophylaxis against graft-versus-host disease (GVHD). Median patient age was 47 years (range, 21-63 years), with 23 patients (77%) older than 40 years. The preparative regimen was well tolerated. Grade 4 toxicities and oral mucositis were not observed. Graft failure did not occur. Severe acute GVHD was observed in 5 patients (17%). The median follow-up was 23 months (range, 6-39 months). Cytogenetic or hematologic relapse was detected in 3 patients (10%), 2 of whom subsequently entered remission following a taper of immunosuppression. Nonrelapse mortality occurred in 5 patients (17%), and the Kaplan-Meier estimate of survival at 2 years was 83% (95% confidence interval, 70%-97%). In summary, this low-dose TBI-based preparative regimen resulted in uniform donor engraftment, with markedly reduced organ toxicity and nonrelapse mortality, in this relatively older cohort of patients with CML.

Abstract
A retrospective analysis was performed on 263 consecutive patients aged over 60 with de novo acute myeloid leukemia (AML) diagnosed in a single institution between 1979 and 1998. Eighty-nine patients (33%) received only palliative treatment, while 174 patients (67%) were treated with different intensive chemotherapy regimens. The 5- and 10-year overall survival (OS) for the whole series was 7.7+/-1.2 and 4.3+/-1.6%, respectively. For patients receiving chemotherapy, OS was 10.5+/-2.5 and 7+/-2.6%, while for those patients receiving supportive treatment it was 1.1+/-1.1 and 0%, respectively (P=0.002). Within the group of patients receiving chemotherapy, the complete remission (CR) rate was 46%; treatment failure rate was 54% (36% due to treatment-related mortality and 18% due to resistant disease). Variables influencing CR rate were FAB subtype, CD7 positivity, chemotherapy regimen, creatinine level, hepatomegaly, and period of diagnosis. Median disease-free survival (DFS) duration was 8.4 months with a probability of being disease-free at 10 years of 10+/-5%. There were no significant differences in DFS according to age. According to the period of diagnosis (1979-1986 vs. 1987-1998), improvements in the CR rate (27 vs. 56%, P=0.0002), and OS (10.9 vs. 15.7 months, P=0.0007) were observed. This large single-center study of unselected de novo AML elderly patients substantiates the progressive improvement achieved in the management of elderly patients with AML, probably due to an improvement in supportive care and the administration of conventional induction chemotherapy.

Abstract
Acute myeloid leukemia (AML) is predominantly a disease of older adults, with more than 50% of cases occurring in adults over 60 years of age. Treatment of AML in older adults is complicated not only by comorbidities that are common in this patient population, but also by the prevalence, in this age group, of forms of AML with a poor prognosis. The problems encountered and the strategies that have been used to improve the outlook in older adults with AML are presented. The two main strategies for improving outcomes in older adults with AML are to develop effective chemotherapeutic regimens with improved tolerability, and to reduce drug resistance. In studies to identify optimal chemotherapeutic regimens in older adults, a satisfactory balance between efficacy and toxicity has not yet been achieved. Also, the use of growth factors to promote hematopoietic recovery has yet to yield consistent reductions in treatment-related morbidity or mortality. Drug resistance can be modified by inhibiting drug efflux mechanisms or by increasing sensitivity to cytotoxic agents, but these strategies have not yet been shown to significantly affect outcomes. Novel approaches including antibody-targeted and molecular-targeted chemotherapy may have the potential to improve the prognosis for older adults with AML.

Abstract
We are entering an exciting era in the management of chronic myeloid leukemia (CML). This, in part is related to our considerable understanding of the molecular lesion associated with the disease-arguably the best characterized of any malignancy. Although allogeneic hematopoietic cell transplantation remains the sole potentially curative therapy at present, newer agents such as the tyrosine kinase inhibitor STI571 show promise and may eventually replace less specific cytotoxic therapy. This review focuses on the numerous options currently available for treating CML and includes a treatment algorithm.

Abstract
In the last decade, improvements in both non-transplant and transplant therapy have extended the lives of patients with CML, particularly those in chronic phase. The future will probably bring a greater understanding of molecular leukaemogenesis and options for treating CML. Non-transplant therapies in development include novel agents and combination therapy. Transplant strategies seek to decrease regimen-related toxicity and directly manipulate the immune system to eradicate disease. Clinical and laboratory science seems poised to add novel therapies to the armamentarium against CML. It is exciting to contemplate what reviews of CML written 10 years from now will discuss.

Abstract
BACKGROUND Allogeneic stem cell transplantation (SCT) and interferon (IFN)-alpha therapy have significantly improved the prognosis of patients with Philadelphia (Ph) chromosome positive chronic myelogenous leukemia (CML). Both therapies may be suitable for younger patients. The authors reviewed current data to assist in prioritizing these modalities in an individual patient. METHODS The authors reviewed and summarized current data on outcomes of SCT and IFN-alpha therapy in patients with early chronic phase CML. RESULTS Several disease-, patient-, and physician-related factors affect outcomes with both modalities. Interferon-alpha does not induce myelofibrosis. The course of CML is predictable in most patients; sudden emergence of blastic phase; disease is unusual. There is no significant adverse impact of delaying SCT for the 12 months usually necessary to assess cytogenetic response to an IFN-alpha-based regimen. Interferon-alpha may be discontinued some months before SCT and is not associated with an adverse impact on post-SCT outcomes. CONCLUSIONS An individualized risk assessment-based approach is of value in prioritizing SCT and IFN-alpha in younger patients with chronic phase CML. The authors recommend a risk-based therapy algorithm based on the expected SCT associated 1-year mortality for an individual patient.

Abstract
Chronic myelogenous leukemia is a myeloproliferative disorder. It is characterized by a biphasic or triphasic clinical course in which a benign chronic phase is followed by transformation into an accelerated and blastic phase. On a cytogenetic and molecular level, most patients with chronic myelogenous leukemia demonstrate BCR-ABL fusion genes in hematopoietic progenitor cells, which result from a reciprocal translocation between chromosomes 9 and 22; this translocation leads to a shortened chromosome 22, called the Philadelphia chromosome. Translation of the fusion products yields chimeric proteins of variable size that have increased tyrosine kinase activity. Conventional chemotherapy with hydroxyurea or busulfan can achieve hematologic control but cannot modify the natural disease course, which inevitably terminates in a rapidly fatal blastic phase. Since its introduction in the 1980s, allogeneic stem-cell transplantation has provided the groundwork for a cure of chronic myelogenous leukemia. However, few patients are eligible for this treatment because of donor availability and age restrictions. Therapy with interferon-alpha alone or in combination with cytarabine suppresses the leukemic clone, produces cytogenetic remissions, and prolongs survival. It is an effective alternative first-line treatment for patients ineligible for transplantation. New drugs active against chronic myelogenous leukemia may show increased activity in the transformed phases of the disease. Novel therapies and concepts are developing rapidly; targeted molecules are tyrosine kinases, ras, and messenger RNA through antisense oligonucleotides. Alternative transplantation options, such as stem cells from autologous sources and matched unrelated donors, are expanding. Immunomodulation by adoptive immunotherapy and vaccine strategies hold significant promise for the cure of chronic myelogenous leukemia.

Abstract
BACKGROUND/AIM In previous studies we demonstrated that all patients affected by HCV-positive type II mixed cryoglobulinaemia have a monoclonal B-cell population in peripheral blood mononuclear cells, and that a large fraction of HCV-infected patients develop a monoclonal B-cell expansion, even in the absence of dosable serum cryoglobulins. However, the prevalence of Type II mixed cryoglobulinaemia in HCV-infected individuals seems to be high in Italy, whereas it is very low in Japan. This study was performed to investigate whether there are ethnic differences in the prevalence of asymptomatic HCV-associated monoclonal B-cell expansions. METHODS Forty-four Japanese patients affected by HCV-positive chronic liver disease (two healthy carriers, 31 chronic hepatitis and 11 cirrhosis) were compared with a group of 60 Italian patients (one healthy carrier, 49 chronic hepatitis, and 10 cirrhosis) without dosable levels of cryoglobulins. The monoclonality of peripheral blood mononuclear cells was investigated by RT/PCR analysis of Immunoglobulin gene rearrangements. Liver function tests, rheumatoid factor, cryocrit level, anti-HCV antibodies, HCV-RNA, and HCV genotype were performed according to standard methodology. RESULTS A B-cell monoclonal population was found in 26% of Italian patients, whereas all Japanese patients were negative. No correlation was found between B-cell monoclonality and severity of liver disease, length or source of the infection, HCV genotype, sex, clinical and biochemical parameters. CONCLUSIONS This study indicates that a monoclonal B-cell proliferation in peripheral blood mononuclear cells is common in HCV infection, but only in Italy, whereas it is absent in Japan. This explains the very low prevalence of Type II mixed cryoglobulinaemia in HCV-positive Japanese subjects, and suggests that HCV is able to determine a B-cell expansion only in the presence of, presently undetermined, host factors.

Abstract
The present retrospective analysis is based on data of 213 patients with chronic myeloid leukaemia (CML). They were treated with interferon (IFN)alpha-2C (Berofor) at daily doses of 3.5 MU subcutaneously (s.c.), alone or in combination with low-dose ara-C or hydroxyurea, according to four consecutive studies of the Austrian CML Study Group. Comparisons were made between 41 patients aged > or = 60 years and 172 younger patients. The elderly patients (median: 64 years; range: 60-73) showed similar pretreatment characteristics compared with the younger group, but included a higher percentage of Sokal Stage three (51 vs 20%). Median observation periods were similar (38 vs 39 months), whereas the duration of IFNalpha treatment was shorter in the elderly group (median 57 vs 42 weeks). The rate of overall haematological responses (73 vs 78%) and complete haematological response (44 vs 54%), was similar in both cohorts. Differences seen in partial (5 vs 12%) and complete cytogenetic response (10 vs 13%), were not statistically significant, but a tendency in favour of the younger cohort had to be noted. Summing up, in elderly patients acceptable rates of haematological and cytogentic response can be expected after treatment with IFNalpha alone or in combination with LD ara-C or HU.

Abstract
Chronic myelogenous leukemia (CML) is a chronic myeloproliferative disorder with an initially chronic course lasting for 3-5 years. It eventually transforms into accelerated and blastic phases, which are generally fatal. CML was one of the first diseases in which a specific chromosomal abnormality was identified, a t(9;22)(q34;q11) or Philadelphia chromosome. CML had been traditionally treated with conventional chemotherapy with hydroxyurea or busulfan. Although these agents can achieve hematologic remissions in most patients, no evidence of sustained disappearance of the chromosomal abnormality was evident. Interferon alpha (IFN-alpha) has been able to achieve hematologic and cytogenic remissions in a significant number of patients, and recent studies show a survival advantage for patients treated with IFN-alpha compared with those treated with conventional chemotherapy. The results of these studies are discussed, and the reasons for discordance among different investigators analyzed in this review. Allogeneic bone marrow transplantation (BMT) may be curative in some patients with CML. The benefits and limitations of this approach in the treatment of CML are also discussed and the results of different alternatives compared. Other alternatives of therapy, including newer chemotherapeutic agents, combinations of IFN-alpha with other agents, and autologous BMT, are presented. The availability of very sensitive techniques for detection of the Philadelphia chromosome at the molecular level has allowed the detection of minimal residual disease. The information available on these measurements is also analyzed. Finally, we discuss the alternatives for patients with accelerated and blastic phase CML, as well as the clinical characteristics and prognosis for patients with Philadelphia-chromosome-negative CML.

Abstract
PURPOSE To determine the response rate to interferon-alpha (IFN-alpha) in patients with chronic myelogenous leukemia (CML) aged 60 years and older. PATIENTS AND METHODS Patients with CML aged 60 years and older included in all protocols with INF-alpha therapy for chronic phase CML at the M.D. Anderson Cancer Center were analyzed. They were treated with human leukocyte or recombinant human IFN-alpha 5x10(6) U/m2 daily alone or in combination with hydroxyurea or IFN gamma. The clinical characteristics of the patients were analyzed and their hematologic and cytogenetic responses to IFN-alpha and survival from the initiation of therapy were determined. Results were compared with those of younger patients treated in the same protocols. Treatment-related toxicity was also analyzed. RESULTS Thirty-five of 274 (13%) patients included in trials of IFN-alpha-based regimens for CML were 60 years and older. Older patients had a higher percentage of bone marrow blasts (P = 0.04) and basophils (P = 0.09) than younger patients. Sixty-nine percent achieved a complete hematologic remission with IFN-alpha therapy, and 51% had a cytogenetic response, which was major in 26% and complete (Philadelphia chromosome-positive cells = 0%) in 20%, Their median survival was 64 months, and the estimated 5-year survival rate was 62%. These results were not different from those in younger patients. Twenty-two patients (63%) had at least grade 2 toxicity requiring dose adjustment. The most frequent side effects were neurotoxicity in 31% and chronic fatigue in 29%. CONCLUSIONS Patients with CML 60 years of age and older respond well to IFN-alpha therapy, but experience more toxicity. This therapy should be considered for these patients if they are otherwise in good condition, with careful attention to IFN-alpha toxicity and its management.

Abstract
Individuals of 60 years living in western countries generally have a mean life expectancy of 20 years at least. Therefore, when aged individuals present with AML, it is a necessity and a challenge to treat them as efficiently as possible. AML is mainly a disease of the elderly and accounts for more than 50% of its incidence among the general population. The treatment of older individuals with AML has remained difficult and its success is still limited. While in adults with AML of less than 60 years complete responses above 65% and survival rates of 35% are commonly obtained, progress in the treatment of elderly patients has been relatively small. As of today, approximately 50% of older patients may be induced into remission with chemotherapy, and, among these complete responders, only approximately 1 in 10 will survive free of leukaemia beyond 4 years after diagnosis. In fact, on one hand, these results represent the rationale and motivation for offering chemotherapy to the older population. On the other hand, they emphasize that major obstacles to better cure rates still exist. These stumbling blocks apparently relate to the restricted tolerance of older subjects to the exposure of chemotherapy and probably also a greater probability of unresponsiveness of the leukaemia to cytotoxic therapy. The haematopoietic growth factors still hold some promise and may improve outcome, but for the time being there is insufficient direct evidence to indicate a defined and established role. It is evident that new avenues should be pursued and trials specifically designed for elderly people with AML be conducted. These trials would need to address questions related to the choice of chemotherapeutic drugs (e.g. idarubicin versus mitoxantrone), their dose and schedule selection, the use of multidrug resistance modulators (to overcome intrinsic drug non-responsiveness), and the optimal clinical use of haematopoietic growth factors, including thrombopoietin. Since trials addressing specific questions regarding the development of treatment of elderly patients with AML have remained scarce, the initiation of these studies is sorely needed. One may hope that these clinical trials will provide some of the necessary answers and new clues, and will be useful to advance future therapy of elderly AML patients.

Abstract
BACKGROUND Acute lymphoblastic leukemia (ALL) is the most common malignancy in children. It is now curable in 60-70% of children. Most of the current understanding of the biology and treatment of ALL originates from studies of children. In adults, although much progress has been achieved, ALL is curable in only 20-35% of patients. METHODS A review of the biology and treatment of ALL from the English literature was performed. RESULTS Immunophenotypic and cytogenetic analyses of ALL have contributed to a more rational classification of ALL. These analyses have identified subgroups with poor prognosis or with different therapeutic requirements. Overall, 60-70% of adults with ALL have poor prognostic features, including older age, a high leukocyte count, non-T-cell immunophenotype, Ph-positive genotype, and longer time to achieve a complete remission. These patients have a cure rate of 20-25%, whereas those without these risk factors, have a 60-70% probability of survival. The use of more intensive induction regimens with growth factor support may improve survival rates. Also, intensive consolidation-intensification may improve survival rates. Most patients benefit from maintenance therapy, but the dose schedule must be optimized. Central nervous system (CNS) prophylaxis is beneficial, particularly for patients with a high risk for CNS relapse and when introduced early during induction of remission. Patients with high risk characteristics may benefit from allogeneic bone marrow transplantation (BMT) during first remission, and all other patients may benefit from it during first or subsequent relapse. Autologous BMT may be a valuable option for poor compliant patients. CONCLUSIONS Although the prognosis of patients with ALL has improved markedly during the past decades, newer strategies, including more dose-intensive therapy, the search for new drugs, and more target-specific therapy, are needed to improve the current cure rates.

Abstract
The Danish Thorotrast Study was recently reestablished and improved. The cohort has been reidentified and followed up, and now comprises 1003 Thorotrast-exposed patients. For all suspected haematological cases, cytological and histological material has been revised and malignant diseases have been reclassified. The numbers of cases of leukemia and other related haematological disorders were as follows: 16 acute myeloid leukemia (AML); 8 myelodysplastic syndrome (MDS); 1 acute lymphatic leukemia (ALL); 3 chronic myeloid leukemia (CML); 4 non-Hodgkin's lymphoma (NHL); 2 multiple myeloma (MM); 2 myelofibrosis (MF); 2 chronic lymphatic leukemia (CLL). Except for CLL, all cases might be Thorotrast-induced. (Expected number of leukemias: < 2.5.) The findings in the German, Japanese, Portuguese and Danish studies are very similar. Some of the characteristic features include a high incidence of AML with several erythroleukemias, many cases of MDS, and a relatively low incidence of CML. In several studies of leukemia induced by alkylating agents, erythroleukemia is also described as a prominent feature. The possibility exists that a phase of relative predominance of erythroid elements in the bone marrow may be a common and not an unusual feature in the pathogenesis of these secondary leukemias. The findings are also compared with histopathological data from a Danish control group of de novo leukemia patients and from atomic bomb survivors with radiation-induced leukemia. The relative frequency of AML is higher among the Thorotrast-exposed patients than among the Danish control group and the A-bomb survivors. In contrast, low relative frequencies are seen for ALL and CML in Thorotrast cases in comparison with de novo leukemia cases and A-bomb survivors. It can be concluded that differences in relative and absolute frequency of leukemias and myelodysplastic syndrome exist not only between the irradiated populations and the unexposed control group, but even between groups exposed to low-LET (linear energy transfer) and high-LET radiation.

Abstract
Acute myeloid leukaemia (AML) is predominantly a disease of the elderly; the median age of incidence is 64 years, and 60% of all cases are over 60. With improved chemotherapy regimens and maximal supportive care, remission rates of up to 60% may be achieved in selected elderly patients. Whilst intensive chemotherapy is the treatment of choice for fit patients, it may be inappropriate for debilitated patients with poor prognosis disease in whom supportive care or palliative chemotherapy may be more suitable. AML in the elderly exhibits biological differences from AML in younger patients, and elderly patients may be unable to withstand the rigors of the intensive treatment regimens given to younger patients. We review methods to evaluate prognostic factors, the development and application of prognostic models, and available data regarding prognostic factors in elderly patients with AML. We discuss a rationale for the use of prognostic factors in selecting therapy for patients and for tailoring of therapy according to disease and host related variables.

Abstract
One hundred and eight adult patients with acute leukemia were diagnosed in the middle Norwegian health region during the 5-year period 1984-88, giving an incidence rate of 4.6/100,000 per year. Nine patients had acute lymphoblastic leukemia (ALL), 93 acute myeloid leukemia (AML) and 6 patients acute leukemia without definite sub-classification. The median age of AML patients was 66 years. Thirty-five patients (median age 78 years) were found non-suitable for cytotoxic drugs, while 58 AML patients (median age 57 years) were given aplasia-inducing drug combinations according to one of three treatment programs depending on the time of diagnosis and age, in order to induce remission. Six patients were given oral drugs or low dose ara-C. All patients were followed until death or for an observation time of more than 5 years (median 7 years). The overall long term survival was found to be 12/108 for all acute leukemias, 8/93 for AML patients and 4/9 for ALL patients. For the AML patients given intravenous aplasia-inducing drugs the remission rate was 0.65, the median remission duration 12.2 months and the 5-year survival rate 0.19. For 31 AML patients, (median age 41 years), started on an intensive chemotherapy program, the 5-year survival rate was 0.32 and the relapse-free 5-year survival rate for the 22 patients entering complete remission was also 0.32.

Abstract
To clarify the histogenesis of B cell chronic lymphocytic leukemia (BCLL), clinicopathological and immunophenotypic studies were performed using a large panel of monoclonal antibodies on 12 cases with BCLL including three cases with prolymphocytic/chronic lymphocytic leukemia (CLL/PL). Immunophenotypically, CD19 and CD20 were positive for all cases of this series and CD5, CD21, CD22, CD23, CD25, CD38, Leu-8, KB-61, and bcl-2 protein were expressed in variable proportion from case to case. CD10, however, did not react. No alkaline phosphatase (ALP) positive cases were found. The phenotype of BCLL was similar to that of B cells of the mantle zone (MZ) of secondary follicle in the lymph node. It is therefore postulated that the neoplastic cells of BCLL in these cases might be derived from B cells of the MZ. Moreover, the cells possibly originated from the lymphocytes located in the inner layer of the MZ, since ALP+ B cells are usually observed in the outer layer of the MZ. The pseudofollicular (PF) pattern was observed in four biopsied lymph nodes among five cases tested, but no such a pattern in an aspiration clot of bone marrow. These four cases consisted of three cases with CLL and a case with CLL/PL. The immunohistochemical study showed that there were many proliferating cells showing Ki-67+ in the PF area of the lymph nodes. In these cases, leukemic cells might have developed from the PF area of the lymph node.

Abstract
BACKGROUND Chronic lymphoproliferative disorders are considered rare in Oriental patients and are thought to constitute only 2% of all leukemias in these patients, compared to 20-30% in Western patients. We conducted a retrospective analysis of Chinese patients with chronic lymphoproliferative disorders to define the frequency and spectrum of these disorders. METHODS A consecutive series of Chinese patients with leukemia and lymphoproliferative disorders seen at two regional hospitals in Hong Kong were analyzed retrospectively. The diagnosis of chronic lymphoproliferative disorders was based on morphologic and immunologic criteria proposed by the French-American-British Cooperative Study Group. RESULTS Sixty-four Chinese patients with chronic lymphoproliferative disorders were identified, and these patients constituted 19% of a total of 342 cases of leukemia diagnosed in 3 years. Chronic lymphocytic leukemia was the most common form, occurring at a frequency of 12.5% of all leukemias. The clinicopathologic features of these patients were similar to those of Western patients, except that Chinese patients tended to present with more advanced (Rai's Stages III and IV; Binet's Stage C) and bulky (splenomegaly > 9 cm) disease, and expressed lambda light chain about six times more frequently. Other chronic lymphoproliferative disorders identified in this study included prolymphocytic leukemia, mantle zone lymphoma, hairy cell leukemia, splenic lymphoma with villous lymphocytes, large granular lymphocyte leukemia, and Sezary syndrome. The authors did not identify any case of human T-cell lymphotropic virus-I-related lymphoproliferative disorders within the study period. CONCLUSION In addition to providing the frequencies of various chronic lymphoproliferative disorders in southern Chinese people, this study also showed that these disorders no longer should be considered rare in this population. Inherent biologic differences between lymphoproliferative disorders in Chinese and Western patients also may exist.

Abstract
Thirty-two consecutive, unselected acute myeloid leukemia (AML) patients (pts) of all FAB-subtypes with a median age of 68 years were treated with intensive induction chemotherapy consisting of one or two cycles of daunorubicin 30 mg/m2 day 1-3 and Ara C 100 mg/m2 as continuous infusion day 1-7. The overall CR rate was 50%, 14/24 (58%) in de novo AML, and 2/8 (25%) with preceding MDS. One patient achieved a PR of 21 months duration, 3 pts died within 7 days of the induction treatment (ED), 6 died during hypoplasia (HD), and 6 remained refractory to 2 cycles of induction. Four pts died after achieving CR. Of the remaining 12 responders, 11 pts received 2 cycles of consolidation consisting of daunorubicin 30 mg/m2 day 1, and Ara C 100 mg/m2 continuous IV infusion day 1-7. No deaths were observed during consolidation. DFS and survival of responders were 7 and 13 months respectively, survival of all pts, responders and non-responders, was 7 months. Large cooperative trials are necessary to identify those elderly pts who may benefit from intensified consolidation treatment.

Abstract
With an increasing number of elderly patients presenting with acute myeloid leukaemia and with recent reports of worthwhile remission rates and survival times following treatment with intensive chemotherapy, there is a pressing need to identify criteria to assist in the selection of appropriate therapy for elderly patients. We have performed multivariate Cox proportional hazard regression analysis of data prospectively collected during the treatment of 104 patients aged 60 and over treated in a multi-centre study with a standardized regimen of mitozantrone and cytosine arabinoside for induction and consolidation. Four readily available parameters, namely urea, performance status, peripheral blood blast count and presence of hepatomegaly, were identified from which a prognostic model to predict survival has been developed. The model was found to be accurate in predicting survival in the cohort of patients from which it was developed, but needs to be validated in a further test population studied prospectively. Its simplicity suggests that it may be particularly useful in the selection of elderly patients with AML most likely to benefit from intensive chemotherapy.

Abstract
We have prospectively evaluated a regimen of mitozantrone and cytosine arabinoside (Ara-C) as first-line therapy in elderly patients with acute myeloid leukaemia (AML). One hundred and four patients with a median age of 68 (range 60-81) were studied, in whom 86 had de-novo AML, and 18 had preceding myelodysplasia or secondary AML. Complete remission was achieved in 64% of de-novo cases, in 28% of MDS/secondary cases, and in 58% overall. The incidence of early death within 28 d of chemotherapy was 11%. The median disease-free survival (DFS) was 11 months with an actuarial DFS of 15% at 43 months. The median overall survival was 9 months with an actuarial survival of 10% at 44 months. The incidence of non-haematological toxicity was acceptably low, and usually of mild to moderate severity. Quality of life was improved, or unchanged, in 90% of responders. We conclude that mitozantrone and ara-C is an effective and well-tolerated regimen which produces high remission rates in elderly patients with AML.

Abstract
This retrospective epidemiologic study on 256 cases of Acute Promyelocytic Leukemia (APL) observed in 20 Italian hematology centers between 1980 and 1988 demonstrated that APL is different from the other acute non-lymphocytic leukemias (ANLL). The male/female ratio was 0.9; median age at diagnosis was 40 years (with 80% of patients between 15 and 54 years of age). The minimal annual incidence of APL in Italy per 1,000,000 inhabitants was estimated to be 0.6; an increased incidence was observed in spring and in autumn. The overall median survival duration of APL patients was 12.6 months. From an epidemiological point of view APL is a distinctive subtype of ANLL.

Abstract
34 out of 403 apparently unselected adult patients with acute leukaemia referred to a single department from 1970 through 1989 survived more than 3 years. The cumulative rate of relapse after 3 years was 39% in patients with acute myeloblastic leukaemia (AML) and 74% in patients with acute lymphoblastic leukaemia (ALL). The latest relapse was observed 75 months after diagnosis in AML and 98 months after diagnosis in ALL. 65% of the long-term survivors were able to undertake normal physical activity, 26% had decreased activity, and 9% were unable to work. 5-year survival for all patients, whether treated or not, during two successive decades was 16% versus 18% and 5% versus 6%, respectively, for ALL and AML. The departmental results were identical with population-based national results. Only in patients 15-49 years of age with AML was there evidence that more intensive treatment had led to better survival.

Abstract
Mortality and morbidity rates for childhood leukemia are examined with reference to time trends and racial differences. Prior to 1964, white and nonwhite children had very different acute lymphocytic leukemia (ALL) mortality rates. With the advent of successful chemotherapy, the mortality rate of ALL in white children has decreased resulting in virtually no racial differences in ALL mortality. The reasons for a stable ALL mortality rate in nonwhite children despite successful chemotherapy include poor access to health care, undefined socioeconomic factors and a biologically different type of ALL occurring in nonwhite children. Recent data from two cancer surveys (1969-1971, 1973-1976) reveal that nonwhite children have a lower incidence of ALL than white children. Underreporting in the nonwhite children could partly account for the difference, but other contributing factors might include a genetic predisposition, undefined socioeconomic influences, and perhaps, a viral agent. Further studies of the factors contributing to racial differences in ALL incidence and mortality are needed.

Abstract
A consecutive series of patients (1978-1981) comprising all patients with acute leukaemia from a population of 475000 inhabitants was reviewed. Thus, 94 patients were diagnosed as having acute leukaemia. No patients were lost from follow-up. The incidence figures of ALL and AML differed significantly from those of Sweden as a whole. 9 patients were less than 15 years old. The median age of adult patients was 64 years, 60.8% being greater than or equal to 60 years old. Of adult patients with AML, 20% had a preleukaemic history (chronic myeloproliferative disorders, myelodysplastic syndromes and others). None of 6 patients with leukaemia as a metamorphosis of a chronic myeloproliferative disorder achieved a complete remission. The overall remission rate of the remaining adult patients was 25%. Treated patients, 15-39 years old, with AML without any preleukaemic history, had a complete remission rate of 80% compared to 12% for patients greater than or equal to 60 years old with the same diagnosis. Of 60 patients with 'primary' AML, 14 were not treated, mainly because of advanced age and complicating diseases. Most of these patients died within a week of admission.

Abstract
Dramatic increases in mortality from multiple myeloma have been reported in the United States and the United Kingdom over the past three decades. To assess what fraction of this increase, if any, might be attributable to a change in the incidence of this disease, we examined the incidence of multiple myeloma during 1950 to 1979 in Malmö, Sweden, a city chosen because of its medical community's longstanding interest in this disease. The average annual incidence rates per 100,000 population were 4.9 for males and 3.7 for females (adjusted to the European age-standardized population). These rates are among the highest in the world. Unlike secular trends for myeloma in the United States and the United Kingdom, where large increases in mortality rates have been reported, the rates in Malmö have increased only slightly, and the increase was restricted to males, suggesting the possibility of environmental causes. We suggest that the rates in Malmö may represent the asymptote of myeloma's incidence that will be approached in other white populations as case ascertainment among them becomes complete.

Abstract
The study is based on the material of acute leukaemia in Norway 1957-81 from the Cancer Registry of Norway. The age-adjusted incidence rates for both sexes have been unchanged. For childhood leukaemias (0-14 years at diagnosis) the age-specific incidence rates have been constant for both sexes and there has been an almost constant incidence for the 5 year birth cohorts 1950-69. Among adults there has been virtually unchanged age-specific incidence rates for most age-groups between 15 and 74 for both sexes. Among those older than 75 years, an increase is seen, most probably due to better diagnostic procedures. No geographic differences were found in age-specific incidence rates.
