Elderly patients comprise a heterogeneous population. Comprehensive geriatric assessment (CGA) is an established diagnostic tool in geriatric medicine. However, the prognostic value in patients with ML is unclear. We sought to establish a relationship between results of CGA and survival time in patients with ML. Methods Newly diagnosed patients with ML and indication for chemotherapeutical treatment were prospectively recruited in an observational trial. In addition to usual diagnostic work up, a CGA including activities of daily living (ADL), instrumental activities of daily living (IADL) and comorbidities was performed. Association of patients' characteristics and results of CGA with survival were analysed according to Kaplan--Meier method and in a multivariate Cox-regression analysis. Results About 143 patients were included, median age was 63 years, 63 patients were women. Median follow-up of surviving patients was 62 months. Sixty-six patients died within this time. Advanced age, poor Karnofsky performance status, dependence in ADL and IADL and presence of severe comorbidity were significantly associated with shorter survival time. In a Cox-regression analysis, IADL (HR 2.1 95% CI 1.1--3.9) and comorbidity (HR 1.9 95% CI 0.9--3.9) were independent and strongest associated with survival time. Conclusion Results of CGA, such as IADL and comorbidities, are prognostic variables for survival of patients with ML. Results should be validated in homogeneous clinical groups and if confirmed included in diagnostic and therapeutic algorithm.

    Description: Byline: Ulf Schnetzke (1), Peter Fix (3), Baerbel Spies-Weisshart (1), Karin Schrenk (1), Anita Glaser (2), Hans-Joerg Fricke (1), Paul Rosee (1), Andreas Hochhaus (1), Sebastian Scholl (1) Keywords: AML; Relapse; FLT3; Cyclophosphamide; Stem cell transplantation Abstract: Background Approximately, 70 % of adult patients with de novo acute myeloid leukemia (AML) achieve a complete remission (CR) while 10--20 % of AML are refractory to induction chemotherapy. Furthermore, a significant proportion of AML patients in CR will relapse during or after consolidation treatment. There is no evidence for a standard salvage regimen and most centers use a combination of an anthracycline and cytarabine (AraC). The aim of this study was to investigate the impact of two age-adjusted regimens containing AraC and cyclophosphamide applied for the treatment of relapsed or refractory AML. Patients and methods We retrospectively analyzed 60 patients (24 male, 36 female median age 56 years) with relapsed or refractory AML who were treated with a combination of AraC and cyclophosphamide monocentrically between October 2000 and January 2013. Two different protocols containing either high-dose (hAC) or intermediate-dose cytarabin (iAC) have been applied dependent on age and performance status. Results We demonstrate an overall response rate (CR + PR) induced by hAC and iAC of 56.7 %. Importantly, a complete remission rate (CR + CRp) of 52.2 % was found in patients who received the hAC regimen while only 8.8 % of patients achieved a CR following the iAC protocol (p 〈 0.001). The rate of refractory disease was 26.1 and 47.1 %, respectively. High-risk cytogenetics, i.e., a complex aberrant or monosomal karyotype had no effect on achievement of CR after hAC. In addition, there was no impact of activating FLT3 mutations on response to treatment according to the hAC regimen. In the cohort of patients treated with the iAC protocol, treatment-related mortality of 11.8 % within 60 days was observed but none of the patients who received the hAC regimen died within the first 2 months following chemotherapy. The toxicity profile was acceptable at both cytarabine dose levels. Importantly, 19 patients (82.6 %) of the hAC cohort underwent allogeneic hematopoietic stem cell transplantation (HSCT) as consecutive treatment. Conclusion The hAC regimen represents a promising therapeutic approach to induce a second CR in younger patients with relapsed or refractory AML prior to HSCT without using anthracyclines.

    Description: Acute myeloid leukaemia (AML) is mainly affecting elderly patients. Elderly patients are increasingly affected by impairment of functional status (FS). FS is of prognostic relevance for survival in different tumours. Data for patients with AML are rare. Within a prospective trial we recruited patients with newly diagnosed AML and measured FS by two different methods: Karnofsky performance status (KPS) and instrumental activities of daily living (IADL). Sixty-three patients aged 19–85 years (median 61.1) were included. Twenty-three had prior myelodisplastic syndrome (MDS), 7 favourable, 17 unfavourable karyotype. Fifty received induction chemotherapy, 13 palliative chemotherapy. Median survival was 15.2 months (95% CI, 10.8–22.3) in all patients. Age, cytogenetic risk group, and impaired KPS and IADL significantly influenced median survival in univariate analysis. Impairment of IADL was the single most predictive variable. In multivariate analysis, impairment of IADL Score (HR:4.3, 95% CI 1.7–10.5, P  = 0.001) and of KPS (HR:4.8, 95% CI 1.9–12.3, P  = 0.001), and unfavourable cytogenetic risk group (HR:6.0, 95% CI 2.5–14.3, P  〈 0.001) significantly predicted median survival. In patients with AML, FS and not age is a major predictor of survival. The influence of FS is independent from cytogenetic risk group. IADL measurement adds information to KPS. The results have to be confirmed in a large sample of patients.

    Description: Acute myeloid leukemia (AML) is a heterogeneous disease with respect to clinical prognosis and acquired chromosomal aberrations. After routine banding cytogenetic analysis 45% of AML patients show a normal karyotype (NK-AML). For a better understanding of development and progression in AML, it is important to find markers which could be primary genetic aberrations. Therefore, in this study 31 patients with NK-AML were analyzed by new high resolution molecular cytogenetic approaches. A combination of multitude multicolor banding and metaphase microdissection-based comparative genomic hybridization revealed deletions of the subtelomeric regions in 6% of the studied cases. According to these results, locus-specific probes for the subtelomeric regions of chromosomes 5, 9, 11, 12 and 13 were applied on 22 of the studied 31 NK-AML cases. Surprisingly, 50% of them showed deletions or duplications. These aberrations occurred in the in vitro proliferating as well as in the non-proliferating cells. Meta-analysis of the aberrant regions revealed that they often include genes known to be associated with tumors, e.g. RASA3 on chromosome 13. These results implicate that aberrations in the subtelomeric regions of NK-AML occur quite often and may be considered as primary genetic changes, and should not be neglected in future diagnostic approaches.

    Description: The impact of chromosome architecture in the formation of chromosome aberrations is a recent finding of interphase directed molecular cytogenetic studies. Also positive correlation of translocation frequencies and spatial proximity of chromosomes was described. Thus, disease specific chromosomal translocations could be due to tissue specific genomic organization. However, no three-dimensional interphase fluorescence in situ hybridization (FISH) studies for the nuclear architecture of bone marrow (BM) cells have previously been done. In this study, BM of three secondary acute myelogenous leukemia (AML) cases with trisomy 8 and otherwise normal karyotype were evaluated. Bone marrow cells of one AML and one ALL (acute lymphoblastic leukemia) case, peripheral blood lymphocytes and human sperm, all of them with normal karyotype, served as controls. Multicolor banding (MCB) probes for chromosomes 8 and 21 were applied in suspension-FISH (S-FISH). Interestingly, in myeloid bone marrow cells chromosomes 8 (di- and trisomic) and 21 tended to co-localize with their homologue chromosome(s), rather than to be separated. Thus, the co-localization of chromosomes 8 and 21 might promote a translocation providing a selective advantage of t(8;21) cells in AML-M2. In summary, the concept that tissue specific spatial proximity of chromosomes leads to enhanced translocation frequencies was further supported.

    Description: This randomized, open-label, parallel-group, multicenter study was designed to compare the efficacy and safety of bendamustine and chlorambucil in previously untreated patients with advanced (Binet stage B or C) chronic lymphocytic leukemia (CLL). Patients (〈or= 75 years of age) were randomly assigned to receive bendamustine 100 mg/m(2)/d intravenously on days 1 to 2, or chlorambucil 0.8 mg/kg (Broca's normal weight) orally on days 1 and 15; treatment cycles were repeated every 4 weeks for a maximum of six cycles. The response to treatment was assessed according to National Cancer Institute Working Group criteria, and the final determination of response was made by a blinded independent review committee. A total of 319 patients were randomly assigned (162 bendamustine, 157 chlorambucil). Complete or partial responses were achieved in 110 (68%) of 162 bendamustine-treated and 48 (31%) of 157 chlorambucil-treated patients (P 〈 .0001). More patients showed complete responses with bendamustine than with chlorambucil (31% v 2%). Median progression-free survival was 21.6 months with bendamustine and 8.3 months with chlorambucil (P 〈 .0001). Bendamustine was also associated with an improvement in duration of remission, compared with chlorambucil (median, 21.8 v 8.0 months). Hematologic National Cancer Institute Common Toxicity Criteria grade 3 to 4 adverse events were more common with bendamustine than with chlorambucil (occurring in 40% v 19% of patients). Severe infections (grade 3 to 4) occurred in 8% of bendamustine-treated patients and 3% of chlorambucil-treated patients. Bendamustine offers significantly greater efficacy than chlorambucil, and a manageable toxicity profile, when used as first-line therapy in patients with advanced CLL.

    Description: The quantitative analysis of cyclosporin A (CsA) effects might be helpful for optimizing immunosuppressive treatment after allogeneic organ transplantation in individual patients, as rejection can occur despite the existence of CsA blood levels within therapeutic ranges. Previous investigations found that costimulation of the CD28 pathway generally mediates CsA-resistant proliferation of T cell receptor (TCR)-activated T lymphocytes. However, here we describe considerable interindividual variation regarding the immunosuppressive effects of CsA (1000 microg/L) on anti-CD3/CD28 T cell costimulation in a human whole blood assay. In the in vitro study, we found a significant reduction of T cell proliferation, activation marker expression (CD25, CD69) on the T cell surface, and interleukin-2 (IL-2) protein expression in whole blood samples of all healthy subjects (n = 11). However, the investigation of cytokine mRNA profiles revealed variable results of in vitro CsA sensitivity. Whole blood samples of 3 of 11 healthy individuals demonstrated a marked suppression of IL-2 mRNA expression (〉50%) and a partial inhibition of IL-4, interferon-gamma (IFN-gamma), and tumor necrosis factor-alpha (TNF-alpha) mRNA expression on addition of CsA. In contrast, the remaining 8 healthy individuals had cytokine mRNA expression levels that were unaffected or even increased when CsA was administered in vitro. In patients undergoing CsA monotherapy (ex vivo study, n = 9), we found a significant suppression of IL-2 mRNA levels in 4 of 9 patients ex vivo. Thus, we cannot confirm a universal CsA resistance of T cells on anti-CD3/CD28 costimulation. Instead, our results suggest an individual degree of CsA sensitivity that might be more consistent with clinical experience. Prospective studies are necessary to determine if individual degrees of CsA sensitivity correlate with clinical events and are associated with a low or high risk of transplant rejection.
