    Increased immature hematopoietic progenitor cells CD34+/CD38dim in myelodysplasia

    CYTOMETRY, Issue 2 2006
    Mariela B. Monreal
    Abstract Background Myelodysplastic syndromes (MDS) are clonal disorders affecting hematopoietic progenitor cells (HPC). Despite the relevance of clonal CD34+ cells in developing MDS, only few studies analyze the phenotype of this cell population. The aim of this study was to evaluate phenotypic changes on HPC in MDS that could reflect abnormalities in the differentiation process of stem cells. Methods We analyzed the expression of CD38 and HLA-DR on CD34+ cells by flow cytometry in 36 patients with MDS, as well as in healthy donors (n = 12) and patients with other hematological disorders: non-Hodgkin lymphomas and multiple myeloma, both in complete remission (CR) (n = 32); acute lymphoblastic leukemia in CR (n = 17); de novo acute myeloblastic leukemia (AML) at diagnosis (n = 22) and in CR (n = 37); and AML secondary to MDS at diagnosis (n = 19). Cases with available karyotype were grouped according to the International Prognostic Scoring System (IPSS). Results Compared to normal BM, the fraction of immature HPC, characterized as CD34+bright, intermediate FSC/SSC, and CD38dim, was significantly increased in high risk MDS and secondary AML, but not in low risk MDS, (P , 0.001, P = 0.03, and P = 0.7). De novo AML showed decreased immature HPC. High numbers of immature HPC correlated with higher IPSS risk groups (P = 0.05) and showed significant impact on disease progression (P = 0.03). Conclusion Our study confirms that evaluation of CD38 expression pattern on HPC is an easy and reproducible test that allows evaluating the immature subset of progenitor cells. Increased immature HPC in high risk MDS and secondary AML may reflect blocked differentiation of CD34+ cells in these diseases. © 2006 International Society for Analytical Cytology [source]


    Host immunity affects survival in myelodysplastic syndromes: Independent prognostic value of the absolute lymphocyte count,

    AMERICAN JOURNAL OF HEMATOLOGY, Issue 3 2010
    Nisha L. Jacobs
    The prognostic significance of the peripheral blood absolute lymphocyte count (ALC) has been carefully examined in lymphoid malignancies, but the importance of the baseline ALC in chronic myeloid neoplasms is less clear. In a recent analysis of myelodysplastic syndromes (MDS) associated with deletion of chromosome 5q, we observed that an ALC < 1.2× 109 cells/L at diagnosis is independently associated with poorer survival. Clinicopathological data from 503 patients with non-del(5q) MDS evaluated at Mayo Clinic between 1996 and 2007 were reviewed to determine the prognostic impact of ALC at diagnosis in non-del(5q) MDS. Patients with MDS and an ALC at diagnosis ,1.2× 109 (N = 248) experienced a superior overall survival (OS) compared with patients with an ALC < 1.2× 109/L (N = 255, median OS of 26.6 months versus 18.5 months, P < 0.001, respectively). ALC at diagnosis was an independent predictor for OS when compared with the International Prognostic Scoring System and the WHO-based Prognostic Scoring System. This study suggests that ALC at diagnosis is a prognostic factor for OS in MDS, and argues in favor of further studies to assess the role of host immunity in MDS clinical outcomes. Am. J.

    Red blood cell transfusion need at diagnosis adversely affects survival in primary myelofibrosis,increased serum ferritin or transfusion load does not,

    AMERICAN JOURNAL OF HEMATOLOGY, Issue 5 2009
    Ayalew Tefferi
    Serum ferritin level at diagnosis was available in 185 patients with primary myelofibrosis (PMF); twenty-two (12%) patients had serum ferritin >1,000 ng/mL and 32 (17%) were red blood cell (RBC) transfusion-dependent. As expected, RBC transfusion need and increased serum ferritin displayed strong correlation (P < 0.0001); in addition, the latter but not the former correlated with advanced age (P < 0.0001). During median follow-up of 28 months (range 0.5,231), peak serum ferritin levels exceeded 1,000 ng/mL in 41 (22%) patients. On multivariable analysis that included age as a covariate, RBC transfusion need at diagnosis (P < 0.0001), but not increased serum ferritin or transfusion load, predicted shortened survival. The prognostic relevance of RBC transfusion need was independent of the International Prognostic Scoring System and was also illustrated for leukemia-free survival (P = 0.003). In PMF, the presence of a more severe erythropoietic defect, and not iron overload, has additional adverse prognostic value. Am. J. Hematol., 2009. © 2009 Wiley-Liss, Inc. [source]


    Myelodysplastic syndromes associated with interstitial deletion of chromosome 5q: Clinicopathologic correlations and new insights from the prelenalidomide era,,

    AMERICAN JOURNAL OF HEMATOLOGY, Issue 9 2008
    Shernan G. Holtan
    To better estimate prognosis for patients with myelodysplastic syndromes (MDS) associated with clonal interstitial deletions of the long arm of chromosome 5 (del(5q)), we reviewed the medical records of 130 adults with del(5q) MDS seen at our institution over a 15-year period. Overall median survival of this cohort was 9.5 months, shorter than reported in earlier series. The least favorable outcomes are associated with complex cytogenetics, lack of any normal metaphases, normocytic rather than macrocytic erythrocyte indices, and low baseline lymphocyte counts. Lymphopenia but not neutropenia at the time of diagnosis appears to be a new adverse prognostic indicator. Cytogenetic breakpoints defined by G-banded karyotyping correlate poorly with particular disease features. Surprisingly, survival of patients with treatment-related MDS was equivalent to that of de novo MDS with del(5q) in this series. Morphologic features associated with del(5q) are diverse. Most patients with del(5q) MDS do not meet criteria for WHO-defined 5q-syndrome, and the presence of del(5q) does not appear to modify the clinical phenotype otherwise risk-stratified by the International Prognostic Scoring System (IPSS). Additional important prognostic factors not taken into account by the IPSS include the baseline erythrocyte indices, lymphocyte count, and clonal burden. Am. J.

    Evaluation of the prognostic significance of Eosinophilia and Basophilia in a larger cohort of patients with myelodysplastic syndromes

    CANCER, Issue 10 2010
    Friedrich Wimazal MD
    Abstract BACKGROUND: Lineage involvement and maturation arrest are considered to have prognostic significance in patients with myelodysplastic syndromes (MDS). However, although the prognostic value of neutropenia, thrombocytopenia, and monocytosis have been documented, little is known about the impact of eosinophils and basophils. METHODS: The authors examined the prognostic significance of eosinophils and basophils in 1008 patients with de novo MDS. Patients were enrolled from 3 centers of the Austrian-German MDS Working Group and were analyzed retrospectively. Blood eosinophils and basophils were quantified by light microscopy, and their impact on survival and leukemia-free survival was calculated by using Cox regression. RESULTS: Eosinophilia (eosinophils >350/,L) and basophilia (basophils >250/,L) predicted a significantly reduced survival (P < .05) without having a significant impact on leukemia-free survival. In multivariate analysis, eosinophilia and basophilia were identified as lactate dehydrogenase (LDH)-independent prognostic variables with International Prognostic Scoring System (IPSS)-specific impact. Although elevated LDH was identified as a major prognostic determinant in IPSS low-risk, intermediate-1 risk, and high-risk subgroups, the condition "eosinophilia and/or basophilia" was identified as a superior prognostic indicator in the IPSS intermediate-2 risk subgroup. CONCLUSIONS: The evaluation of eosinophils and basophils in patients with MDS was helpful and may complement the spectrum of variables to optimize prognostication in MDS.

    Proposal for a new risk model in myelodysplastic syndrome that accounts for events not considered in the original International Prognostic Scoring System

    CANCER, Issue 6 2008
    Hagop Kantarjian MD
    Abstract BACKGROUND. Recent studies have highlighted issues with the International Prognostic Scoring System (IPSS) model in relation to the exclusion of many subgroups that now represent a large proportion of patients with myelodysplastic syndrome (MDS) (eg, secondary MDS, chronic myelomonocytic leukemia [CMML] with leukocytosis, prior therapy) and its lack of applicability to most patients on investigational programs, because many would have received prior therapies and would have had MDS for a significant length of time. METHODS. The authors analyzed 1915 patients with MDS who were referred from 1993 to 2005 (including those with CMML, secondary MDS, and MDS with prior therapy). Only 507 patients (26%) had primary MDS without prior therapy (ie, classifiable by the IPSS). Patients were divided randomly into a study group (n = 958) and a test group (n = 957). RESULTS. A multivariate analysis of prognostic factors in the study group identified the following adverse, independent factors as continuous and categoric values (P<.001): poor performance, older age, thrombocytopenia, anemia, increased bone marrow blasts, leukocytosis, chromosome 7 or complex (,3) abnormalities, and prior transfusions. Cutoffs for anemia, thrombocytopenia and blasts, and cytogenetic subsets were different according to the IPSS. The new MDS prognostic model divided patients into 4 prognostic groups with significantly different outcomes. The model was validated in the test group. Applying the prognostic score of the new model within the 4 IPSS risk groups, overall, and in patients who had primary MDS without prior therapy was found to be highly prognostic in each subset. Applying the IPSS within each of the 4 risk groups of the new MDS model was not found to be prognostic. CONCLUSIONS. The new model accounts for duration of MDS and prior therapy. It is applicable to any patient with MDS at any time during the course of MDS. Cancer 2008. © 2008 American Cancer Society. [source]


    Thalidomide therapy in adult patients with myelodysplastic syndrome

    CANCER, Issue 4 2006
    A North Central Cancer Treatment Group phase II trial
    Abstract BACKGROUND. Thalidomide has shown promise for the treatment of patients with myelodysplastic syndrome. The current prospective multicenter study examined the efficacy and toxicity of thalidomide in adult patients with myelodysplastic syndrome. METHODS. Using the International Prognostic Scoring System (IPSS), patients were stratified into 2 groups: favorable (IPSS score, 0,1.0) or unfavorable (IPSS score, 1.5,3.5). Seventy-two patients (42 of whom were favorable and 30 of whom were unfavorable) received a starting dose of oral thalidomide of 200 mg daily. The dose was increased by 50 mg per week to a targeted maximum daily dose of 1000 mg. RESULTS. According to the International Working Group response criteria for myelodysplastic syndrome, 1 patient in the unfavorable group achieved a partial remission with a complete cytogenetic response. Overall, 2 patients (5%) in the favorable group and 4 patients (14%) in the unfavorable group experienced either a hematologic improvement or a partial response. The most frequent Grade 3 or 4 (grading was based on the National Cancer Institute's Common Toxicity Criteria [version 2.0]) nonhematologic adverse events were fatigue (24%), infection (19%), neuropathy (13%), dyspnea (8%), and constipation (7%). CONCLUSIONS. Thalidomide alone, at the schedule and dose levels used in the current study, is not a safe and viable therapeutic option for patients with myelodysplastic syndrome. Limited efficacy and increased toxicity were observed in the current Phase II trial. Cancer 2006. © 2006 American Cancer Society. [source]

    Clinical prognostic scoring system to aid decision-making in gastro-oesophageal cancer

    BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 12 2007
    D. A. C. Deans
    Background: Accurate prediction of prognosis in gastro-oesophageal cancer remains challenging. The aim of this study was to develop a robust model for outcome prediction. Methods: The study included 220 patients with gastric or oesophageal cancer newly diagnosed over a 2-year period. Patients were staged and underwent treatment following discussion at a multidisciplinary team (MDT) meeting. Clinical and investigative variables were collected, including performance and nutritional status, and serum C-reactive protein (CRP) level. Primary endpoints were death within 12 and 24 months. Results: Overall median survival was 13 months. Advanced clinical stage (P < 0·001), reduced performance score (P < 0·001), weight loss exceeding 2·75 per cent per month (P = 0·026) and serum CRP concentration above 5 mg/l (P = 0·031) were identified as independent prognostic indicators in multivariable analysis. A prognostic score was constructed using these four variables to estimate a probability of death. Applying the model gave an area under the receiver,operator characteristic curve of 0·84 and 0·85 for prediction of death at 12 and 24 months respectively (both P < 0·001). Conclusion: This model accurately estimated the probability of death within 12 and 24 months. This may aid the MDT decision-making process. Copyright © 2007 British Journal of Surgery Society Ltd.

    Predictive and discriminating three-risk-group prognostic scoring system for staging Hodgkin lymphomas

    CANCER, Issue 2 2007
    Delphine Maucort-Boulch MD
    Abstract BACKGROUND. Several 3-stage Ann Arbor classification-derived prognostic systems were constructed since 1980 to identify the prognosis of Hodgkin lymphoma (HL). Modern statistical tools were applied to 955 patients treated between 1981 and 1996 to build a 3-stage prognostic scoring system (PSS). METHODS. Each variable associated with 10-year overall survival (10-year OS) was assigned to 2 (0 or 1) or 3 (0, 1 or 3) values. By summing the values attributed to each variable, 3 stages were defined. 10-year OS, 5-year event-free survival (5-year EFS), and freedom from progression (5-year FFP) rates of the PSS and of other existing systems were then compared. RESULTS. Four variables were associated with 10-year OS: age (<40 = 0, ,40 = 1), number of involved lymphoid areas (1,2 = 0, 3,4 = 1, ,5 = 2), visceral disease (no = 0, yes = 1), and systemic symptoms (no = 0, yes = 1). Scores 0 and 1, 2 and 3, and ,4 were attributed to 59.7%, 30.9%, and 9.4% of the patients who had 10-year OS rates of 93.5, 75.7, and 53.4% and 5-year EFS / 5-year FFP rates of 91.2%/90.3%, 78.1%/76.3%, and 54.1%/52.6%, respectively. The discrimination and prediction abilities of the PSS were better than those of the other systems tested; moreover, the PSS adequately identified the few patients with a worse prognosis without resorting to the International Prognostic Score for advanced stages. The PSS was also highly predictive for 489 patients treated between 1997 and 2002. CONCLUSION. PSS is a useful alternative to the existing prognostic systems for evaluating HL patients.

    Infection probability score, APACHE II and KARNOFSKY scoring systems as predictors of infection onset in haematology,oncology patients

    JOURNAL OF CLINICAL NURSING, Issue 11-12 2010
    Eleni Apostolopolou
    Aim., To assess the predictive power of three systems: Infection Probability Score, APACHE II and KARNOFSKY score to the onset of healthcare-associated infections in haematology,oncology patients. Background., The high incidence of healthcare-associated infections is a frequent problem in haematology,oncology patients that affects morbidity and mortality of these patients. Design., A retrospective surveillance survey. Method., The survey was conducted for seven months in the haematology unit of a general hospital in Greece to assess the predictive power of Infection Probability Score, APACHE II and KARNOFSKY score to the onset of healthcare-associated infections. The sample consisted of 102 hospitalised patients. The diagnosis of healthcare-associated infections was based on the definitions proposed by CDC. Results., Among the participants, 53 (52%) were males and 49 (48%) were females with a mean age of 53·30 (SD 18·59) years old (range, 17,85 years). The incidence density of healthcare-associated infections (the number of new cases of healthcare-associated infections per 1000 patient-days) was 21·8 infections per 1000 patient-days. Among the 102 patients, healthcare-associated infections occurred in 32 (31·4%) patients who had a total of 48 healthcare-associated infections (47·5%). Among the 38 patients with neutropenia, 26 (68·4%) had more than one healthcare-associated infection. Of the 48 detected healthcare-associated infections, the most frequent type was blood-stream infection (n = 17, 35·4%), followed by Clostridium difficile infection (n = 11, 22·9%) and respiratory tract infection (n = 8, 3·4%). The best cut-off value of Infection Probability Score (IPS) for the prediction of a healthcare-associated infection was 10 with sensitivity of 59·4% and specificity of 74·3%. Conclusions., Between the three different prognostic scoring systems, IPS had the best sensitivity in predicting healthcare-associated infections. Relevance to clinical practice., IPS is an effective tool and should be used from nurses for the early detection of haematology,oncology patients who are susceptible to the onset of a healthcare-associated infection.

    Prospective study of the relationship between the systemic inflammatory response, prognostic scoring systems and relapse-free and cancer-specific survival in patients undergoing potentially curative resection for renal cancer

    BJU INTERNATIONAL, Issue 8 2008

    OBJECTIVE To examine the prognostic value of markers of systemic inflammatory response, together with established scoring systems, in predicting relapse-free and cancer-specific survival in patients with primary operable renal cancer, as there is increasing evidence that such markers provide prognostic information, in addition to scoring systems, in patients with metastatic renal cancer. PATIENTS AND METHODS In all, 83 patients undergoing potentially curative nephrectomy for localized renal cancer were recruited. The University of California Los Angeles Integrated Staging System (UISS), ,Stage Size Grade Necrosis' (SSIGN) and Kattan scores were constructed. The systemic inflammatory response was assessed by counting white cells, neutrophils, lymphocytes and platelets, and measuring albumin and C-reactive protein (CRP) concentrations. RESULTS On multivariate analysis of the significant individual covariates, T stage (hazard ratio 2.38, 95% confidence interval 1.06, 5.36, P = 0.037), necrosis (3.73, 1.26,11.05, P = 0.018) and CRP (4.31, 1.20,15.49, P = 0.025) were significant independent predictors of relapse-free survival. On multivariate analysis of significant scoring systems and CRP, only UISS (3.50, 1.66,7.40, P = 0.001), SSIGN (2.83, 1.19,6.72, P = 0.018) and CRP (4.14, 1.16,14.73, P = 0.028) were significant independent predictors of relapse-free survival. CONCLUSION Elevated circulating CRP levels appear to be better than other markers of the systemic inflammatory response, and independent of established scoring systems, in predicting relapse-free and cancer-specific survival in patients undergoing potentially curative nephrectomy for renal cancer.
