RESUMEN

BACKGROUND: A combination of rituximab with cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) is the standard first-line therapy for diffuse large B cell lymphoma (DLBCL), the most common aggressive lymphoma in adults. One of the major adverse effects of this regimen is vincristine-induced polyneuropathy which leads to discontinuation of vincristine in up to 30% of DLBCL-patients. Dose reduction of vincristine might worsen treatment outcomes of DLBCL but identification of treatment alternatives for patients exhibiting peripheral neuropathy during R-CHOP is an unmet need in hematology. METHODS: In this retrospective cohort study, comprising 987 patients with de novo DLBCL, we delineated the role of vinorelbine as a substitute for vincristine in R-CHOP by measuring improvements in neuropathy and outcome variables. RESULTS: Five-year overall survival (OS) and progression-free survival (PFS) were 72.6% and 63.1% in patients who received regular doses of vincristine, as compared to 60.6% and 51.7% in patients who received reduced doses of vincristine (p = 0.022 and p = 0.003, respectively). Of 199 patients who switched to vinorelbine, the majority experienced an improvement of neuropathy Furthermore, vinorelbine-switched patients showed favorable oncologic outcomes. CONCLUSION: Replacement of vincristine by vinorelbine due to neuropathy is effective and safe, and results in a significant improvement in neuropathy as compared to treatment with R-CHOP.

RESUMEN

This phase II study explored the effects of bortezomib consolidation versus observation on myeloma-related bone disease in patients who had a partial response or better after frontline high-dose therapy and autologous stem cell transplantation. Patients were randomized to receive four 35-day cycles of bortezomib 1·6 mg/m2 intravenously on days 1, 8, 15 and 22, or an equivalent observation period, and followed up for disease status/survival. The modified intent-to-treat population included 104 patients (51 bortezomib, 53 observation). There were no meaningful differences in the primary endpoint of change from baseline to end of treatment in bone mineral density (BMD). End-of-treatment rates (bortezomib versus observation) of complete response/stringent complete response were 22% vs. 11% (P = 0·19), very good partial response or better of 80% vs. 68% (P = 0·17), and progressive disease of 8% vs. 23% (P = 0·06); median progression-free survival was 44·9 months vs. 21·8 months (P = 0·22). Adverse events observed ≥15% more frequently with bortezomib versus observation were diarrhoea (37% vs. 0), peripheral sensory neuropathy (20% vs. 4%), nausea (18% vs. 0) and vomiting (16% vs. 0). Compared with observation, bortezomib appeared to have little impact on bone metabolism/health, but was associated with trends for improved myeloma response and survival.

RESUMEN

BACKGROUND: Lenalidomide has demonstrated remarkable efficacy for therapy of lower-risk myelodysplastic syndromes (MDS) associated with 5q(-). The present evaluation aimed to describe the characteristics and outcomes of low-risk MDS patients treated with lenalidomide in Austria. PATIENTS AND METHODS: For this retrospective, multicenter, observational analysis of MDS patients who received lenalidomide, data were collected at various hospitals in Austria over a period of 3 years. MDS classification, previous and current MDS therapies, and outcome and safety of lenalidomide were evaluated. RESULTS: Forty-six percent of the patients (n = 23) had a 5q(-) syndrome, while 12% (n = 6) exhibited 5q(-) plus additional aberrations or isolated 5q(-) but ≥ 5% blasts in the bone marrow (10%, n = 5). The remaining 32% of patients (n = 16) had MDS with other World Health Organization classifications. Seventy percent belonged to lower International Prognostic Scoring System risk classes. Sixteen centers participated, involving a total of 50 patients. Most frequently used lenalidomide doses were 10 mg and 5 mg on days 1 to 21 of a 28-day cycle. Seventy-five percent of the patients received 11 months of treatment, with a median therapy period of 3.5 months; median follow-up was 3.9 months (range, 0-26 months). Response rate, defined as transfusion independence during the 2 months after lenalidomide therapy, was 64%. Median overall survival was not reached. CONCLUSION: Lenalidomide was well tolerated and is an effective and well-tolerated option for therapy of patients with 5q(-) syndrome but also lower-risk MDS patients with other World Health Organization classifications in clinical practice.

RESUMEN

We analyzed 661 adult patients who underwent single-unit (n = 226) or double-unit (n = 435) unrelated cord blood transplantation (UCBT) following a reduced-intensity conditioning (RIC) consisting of low-dose total body irradiation (TBI), cyclophosphamide, and fludarabine (Cy/Flu/TBI200). Eighty-two patients received rabbit antithymocyte globulin (ATG) as part of the conditioning regimen (ATG group), whereas 579 did not (non-ATG group). Median age at UCBT was 54 years, and diagnoses were acute leukemias (51%), myelodysplastic syndrome/myeloproliferative neoplasm (19%), and lymphoproliferative diseases (30%). Forty-four percent of patients were transplanted with advanced disease. All patients received ≥4 antigens HLA-matched UCBT. Median number of collected total nucleated cells was 4.4 × 10(7)/kg. In the ATG group, on 64 evaluable patients, ATG was discontinued 1 (n = 27), 2 (n = 20), or > 2 days before the graft infusion (n = 17). In multivariate analyses, the use of ATG was associated with decreased incidence of acute graft-versus-host disease (hazard ratio [HR], 0.31; 95% confidence interval [CI], 0.17-0.55; P < .0001), higher incidence of nonrelapse mortality (HR, 1.68; 95% CI, 1.16-2.43; P = .0009), and decreased overall survival (HR, 1.69; 95% CI, 1.19-2.415; P = .003). Collectively, our results suggest that the use of ATG could be detrimental, especially if given too close to graft infusion in adults undergoing UCBT following Cy/Flu/TBI200 regimen.

RESUMEN

Although mast cells (MC) play an important role in allergic reactions, their physiologic role remains unknown. In mice, several models of MC-deficiency have been developed. However, no comparable human model is available. We examined the in vitro- and in vivo effects of the KIT-targeting drug imatinib on growth and development of human MC. Imatinib was found to inhibit stem cell factor (SCF)-induced differentiation of MC in long-term suspension cultures (IC50: 0.01 µM). Correspondingly, long-term treatment of chronic myeloid leukemia (CML) patients with imatinib (400 mg/day) resulted in a marked decrease in MC. In patients with continuous complete molecular response during therapy, bone marrow MC decreased to less than 5% of pre-treatment values, and also serum tryptase concentrations decreased significantly (pre-treatment: 32.0 ± 11.1 ng/ml; post-therapy: 3.4 ± 1.8, p<0.01). Other myeloid lineages, known to develop independently of KIT, were not affected by imatinib-therapy. Imatinib also produced a substantial decrease in MC-development in mice. However, no clinical syndrome attributable to drug-induced MC-deficiency was recorded in our CML patients. Together, imatinib suppresses MC production in vitro and in vivo. However, drug-induced MC depletion is not accompanied by adverse clinical events, suggesting that MC are less relevant to homeostasis in healthy tissues than we assumed so far.

RESUMEN

The anthracycline doxorubicin plays a major role in the treatment of lymphoproliferative disorders. However, its use is often limited due to cardiac toxicity, which seems to be much less in the liposomal non-pegylated formulation (Myocet®). The aim of this study was the evaluation of efficacy and toxicity of Myocet®-containing treatment regimens, with a focus on cardiotoxicity during treatment in lymphoma patients. A total of 326 consecutive patients, treated between March 2008 and December 2013 in 11 Austrian and 1 Italian cancer centers, were retrospectively assessed. Patients' baseline and treatment-related parameters were obtained by reviewing hospital records. Median age was 74 years (range 26-93). The most common histology was DLBCL (60 %), followed by FL (13 %) and MCL (8 %). At least one cardiovascular comorbidity was present in 72 % of patients. Most common grade 3/4 toxicities were hematologic, namely, leukopenia, neutropenia, thrombocytopenia, and febrile neutropenia in 44, 40, 17, and 16 %. Overall, 43 patients suffered a cardiac event (any grade) with most patients developing congestive heart failure. Parameters significantly associated with severe cardiac events (grades 3-5) were the presence of cardiovascular comorbidities, chronic obstructive pulmonary disease, and elevated baseline NT-proBNP. Treatment response after first line Myocet®-containing therapy was ≥58 % among all entities (range 58-86 %) and therefore comparable to those of conventional therapeutic regimens. Herein, we provide a detailed toxicity profile of Myocet®-containing chemotherapy regimens. Despite the high rate of patients with preexisting comorbidities, the number of adverse events was encouraging. However, these results need to be confirmed in a prospective randomized trial.

RESUMEN

Data on efficacy and safety of azacitidine in acute myeloid leukemia (AML) with >30 % bone marrow (BM) blasts are limited, and the drug can only be used off-label in these patients. We previously reported on the efficacy and safety of azacitidine in 155 AML patients treated within the Austrian Azacitidine Registry (clinicaltrials.gov identifier NCT01595295). We herein update this report with a population almost twice as large (n = 302). This cohort included 172 patients with >30 % BM blasts; 93 % would have been excluded from the pivotal AZA-001 trial (which led to European Medicines Agency (EMA) approval of azacitidine for high-risk myelodysplastic syndromes (MDS) and AML with 20-30 % BM blasts). Despite this much more unfavorable profile, results are encouraging: overall response rate was 48 % in the total cohort and 72 % in patients evaluable according to MDS-IWG-2006 response criteria, respectively. Median OS was 9.6 (95 % CI 8.53-10.7) months. A clinically relevant OS benefit was observed with any form of disease stabilization (marrow stable disease (8.1 months), hematologic improvement (HI) (9.7 months), or the combination thereof (18.9 months)), as compared to patients without response and/or without disease stabilization (3.2 months). Age, white blood cell count, and BM blast count at start of therapy did not influence OS. The baseline factors LDH >225 U/l, ECOG ≥2, comorbidities ≥3, monosomal karyotype, and prior disease-modifying drugs, as well as the response-related factors hematologic improvement and further deepening of response after first response, were significant independent predictors of OS in multivariate analysis. Azacitidine seems effective in WHO-AML, including patients with >30 % BM blasts (currently off-label use). Although currently not regarded as standard form of response assessment in AML, disease stabilization and/or HI should be considered sufficient response to continue treatment with azacitidine.

RESUMEN

The status of umbilical cord blood transplantation (UCBT) in adults with Philadelphia-positive acute lymphoblastic leukaemia (Ph+ALL) and the impact of minimal residual disease (MRD) before transplant are not well established. We analysed 98 patients receiving UCBT for Ph+ALL in first (CR1) or second (CR2) complete remission (CR1, n = 79; CR2, n = 19) with MRD available before UCBT (92% analysed by reverse transcription polymerase chain reaction). Median age was 38 years and median follow-up was 36 months; 63% of patients received myeloablative conditioning and 42% received double-unit UCBT. Eighty-three patients were treated with at least one tyrosine kinase inhibitor before UCBT. MRD was negative (-) in 39 and positive (+) in 59 patients. Three-year cumulative incidence of relapse was 34%; 45% in MRD+ and 16% in MRD- patients (P =0·013). Three-year cumulative incidence of non-relapse mortality was 31%; it was increased in patients older than 35 years (P = 0·02). Leukaemia-free survival (LFS) at 3 years was 36%; 27% in MRD+ and 49% in MRD- patients (P = 0·05), and 41% for CR1 and 14% for CR2 (P = 0·008). Multivariate analysis identified only CR1 as being associated with improved LFS. In conclusion, MRD+ before UCBT is associated with increased relapse. Strategies to decrease relapse in UCBT recipients with Ph+ALL and MRD+ are needed.

RESUMEN

To determine whether umbilical cord blood transplantation (UCBT) is an alternative cure for myelofibrosis (MF), we evaluated 35 UCBTs reported to Eurocord. Seven patients had secondary acute myeloid leukemia (AML) at UCBT, and median age at UCBT was 54 years. Twenty-four patients received a reduced-intensity conditioning (RIC) regimen, and 17 of 35 patients received total body irradiation (2 to 12 Gy)-fludarabine-cyclophosphamide (TCF) conditioning. The median follow-up was 24 months. The cumulative incidence of neutrophil recovery at 60 days was 80%. Fifteen patients relapsed after UCBT. The 2-year overall survival and event-free-survival (EFS) rates were 44% and 30%, respectively. All patients given TCF achieved neutrophil and platelet recovery, and the use of TCF was associated with superior EFS in the RIC population (44% versus 0%, P = .001). Patients with transformation to AML had similar outcomes to patients with less advanced stages. In conclusion, despite graft failure remaining a major concern, the role of UCBT in the management of MF, especially using RIC TCF-based regimens, deserves further investigation to improve results.

RESUMEN

Recent data suggest that azacitidine may be beneficial in CMML. We report on 48 CMML-patients treated with azacitidine. Overall response rates were high (70% according to IWG-criteria, including 22% complete responses). Monocyte count and cytogenetics adversely affected survival, whereas age, WHO-type, FAB-type, and spleen size did not. Matched-pair analyses revealed a trend for higher two-year-survival for azacitidine as compared to best supportive care (62% vs. 41%, p=0.067) and longer OS for azacitidine first-line vs. hydroxyurea first-line (p=0.072, median OS 27.7 vs. 6.2 months). This report reinforces existing evidence that azacitidine is safe and efficacious in both myelodysplastic and myeloproliferative CMML.

RESUMEN

Given the poor outcome of relapsed and refractory peripheral T cell lymphoma (PTCL), we explored a combination of lenalidomide, vorinostat, and dexamethasone to test the feasibility of this therapy in relapsed and refractory PTCL. Eight patients were accrued: two peripheral T cell lymphoma, unspecified; five angioimmunoblastic T cell lymphoma; and one ALK-negative anaplastic large-cell lymphoma. A dose escalation of lenalidomide (days 1-21, q28) was planned using a 3 + 3 design. As two patients treated with 10 mg/day experienced dose-limiting toxicity (thrombocytopenia grade 3, stroke grade 4), the primary end point of our trial was reached; the maximal tolerable dose of lenalidomide was 5 mg/day (level -I). Adverse events grade ≥3 were observed as thrombocytopenia (23 %), leukocytopenia (15 %), anemia (8 %), and neutropenia (8 %). One complete remission (10.3 months), one partial remission (11.3 months), one stable disease (11.9 months), and four progressive disease (overall response rate 25 %) were observed. The median progression-free survival was 2.2 months and the median OS was 6.7 months. In conclusion, the poor results obtained with lenalidomide in combination with vorinostat and dexamethasone provide no arguments that could justify further investigation of this drug combination for the treatment of relapsed PTCL.

RESUMEN

Central nervous system recurrence in acute lymphoblastic leukemia (ALL) occurs in up to 15% of patients and is frequently associated with poor outcome. The purpose of our study was to evaluate the efficacy and safety of a slow-release liposomal formulation of cytarabine for intrathecal (IT) meningeal prophylaxis in patients suffering from ALL. Forty patients aged 20-77 years (median 36) were preventively treated with a total of 96 (range 1-6) single doses containing 50 mg of liposomal cytarabine on a compassionate use basis. After a median observation period of 23 months (range 2-118) only two patients experienced a combined medullary-leptomeningeal disease recurrence after primary diagnosis. Except for headache grade 2 in two patients, no specific toxicity attributable to IT liposomal cytarabine application was noted. Long-term neurological side effects were not observed. IT liposomal cytarabine therapy with concomitant dexamethasone appears to be feasible and well tolerated.

RESUMEN

Bendamustine with bortezomib and dexamethasone was evaluated in 79 patients with relapsed/refractory multiple myeloma. Median age was 64 years, and patients had a median of 2 prior treatment lines (range, 1 to 6 lines). Bendamustine 70 mg/m(2) days 1 and 4; bortezomib 1.3 mg/m(2) intravenously days 1, 4, 8, and 11; and dexamethasone 20 mg days 1, 4, 8, and 11 once every 28 days was given for up to 8 cycles. Primary end point was overall response rate (ORR). Secondary end points were progression-free survival (PFS), overall survival, time to response, and toxicity. ORR was 60.8%, and when minor responses were included, 75.9%. Median time to response was 31 days. ORR rate was similar in patients previously exposed to bortezomib, lenalidomide, and bortezomib plus lenalidomide. PFS was 9.7 and OS was 25.6 months. Multivariate analysis showed high lactate dehydrogenase, ≥3 prior treatment lines, and low platelet counts correlating with short survival. Grade 3/4 thrombocytopenia was noted in 38%, and grade 3/4/5 infections were noted in 23%. Grade ≤2 polyneuropathy increased from 19% at baseline to 52% at cycle 8 and grade 4, from 0% to 7%. Bendamustine-bortezomib-dexamethasone is active and well tolerated in patients with relapsed/refractory myeloma. This trial was registered in the EudraCT database as No. 2008-006421-13.

OBJECTIVE: The Austrian Azacitidine Registry is a multi-center database (ClinicalTrials.gov: NCT01595295). The nature and intent of the registry was to gain a comprehensive view of the use, safety and efficacy of the drug in a broad range of AML-patients treated in real-life scenarios. PATIENTS AND METHODS: The sole inclusion criteria were the diagnosis of WHO-AML and treatment with at least one dose of azacitidine. No formal exclusion criteria existed. A total of 155 AML-patients who were mostly unfit/ineligible for intensive chemotherapy, or had progressed despite conventional treatment, were included. True ITT-analyses and exploratory analyses regarding the potential prognostic value of baseline-variables/performance-/comorbidity-/risk-scores on overall survival (OS), were performed. RESULTS: In this cohort of 155 pretreated (60%), and/or comorbid (87%), elderly (45% ≥75 years) AML-patients, azacitidine was well tolerated and efficacious, with an overall response rate (CR, mCR, PR, HI) of 45% in the total cohort (ITT) and 65% in patients evaluable according to IWG-criteria, respectively. Pre-treatment with conventional chemotherapy (P = .113), age ≤/>80 years (P = .853), number of comorbidities (P = .476), and bone marrow (BM) blast count (P = .663) did not influence OS. In multivariate analysis hematologic improvement alone (without the requirement of concomitant bone marrow blast reduction), although currently not regarded as a standard form of response assessment in AML, was sufficient to confer OS benefit (18.9 vs. 6.0 months; P = .0015). Further deepening of response after first response was associated with improved OS (24.7 vs. 13.7 months; P < .001). CONCLUSIONS: In this large cohort of AML-patients treated with azacitidine, age >80 years, number of comorbidities and/or BM-blasts >30% did not adversely impact OS.

RESUMEN

Currently, there is no standard systemic treatment for extranodal marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue. Both rituximab and cladribine have shown some activity in this disease, but the combination has not been tested so far. In view of this, we initiated a phase II study to assess the activity and safety of rituximab and cladribine in patients with histologically verified mucosa-associated lymphoid tissue lymphoma. Treatment consisted of rituximab 375 mg/m(2) i.v. day 1 and cladribine 0.1 mg/kg s.c. days 1 - 4 every 21 days. In case of complete remission after two courses, another two cycles of therapy were administered, while patients with a partial response or stable disease were scheduled to receive six cycles of treatment. Out of 40 evaluable patients (14 female, 26 male), 39 received treatment as scheduled while one patient died before initiation of therapy and was rated as having progressive disease in the intent-to-treat analysis. Twenty-one patients had gastric lymphoma, while 19 suffered from extragastric mucosa-associated lymphoid tissue lymphoma. Side effects consisted mainly of hematologic toxicity including leukopenia, lymphopenia, anemia and thrombocytopenia. Twenty-three patients had a complete remission (58%) and nine had a partial remission (23%) for an overall response rate of 81%, while five had stable disease (13%) and two progressed during therapy. After a median follow-up of 16.7 months (interquartile range: 15.9 - 18.7 months), 35 patients are alive (88%) while four patients have died and one patient withdrew consent and did not allow further follow up. Our data demonstrate that rituximab plus cladribine is active and safe in patients with mucosa-associated lymphoid tissue lymphoma.

RESUMEN

PURPOSE: We report on a multicenter phase II trial of (90)yttrium-ibritumomab-tiuxetan ((90)YIT) as first-line stand-alone therapy for patients with follicular lymphoma (FL). PATIENTS AND METHODS: Fifty-nine patients with CD20(+) FL grade 1 to 3a in stages II, III, or IV, age 50 years old or older requiring therapy were enrolled. They received (90)YIT according to standard procedure. If complete response (CR) or unconfirmed complete response (CRu) without evidence for minimal residual disease (MRD) 6 months after application of (90)YIT was achieved, patients were observed without further intervention. The same applied to patients with partial response (PR) or with stable disease (SD). Patients with CR but with persisting MRD were to receive a consolidation treatment with rituximab. Primary end point was the clinical and molecular response rate. Secondary end points were time to progression, safety, and tolerability. RESULTS: Six months after treatment with (90)YIT, 56% of the patients showed a CR or CRu and 31% achieved a PR. After a median follow-up of 30.6 months, the progression-free survival (PFS) was 26 months. There was a trend for shorter PFS in patients with increased lactate dehydrogenase (LDH). Of the 26 patients who had CR 12 months after (90)YIT, only three had relapsed. Median time to next treatment has not been reached. The most common toxicities were transient thrombocytopenia and leukocytopenia. Nonhematologic toxicities never exceeded grade 2 according to Common Terminology Criteria for Adverse Events (CTCAE v2.0). CONCLUSION: (90)YIT is well tolerated and achieves high response rates. Patients with increased LDH tend to relapse earlier, and individuals in remission 1 year after (90)YIT appear to have long- lasting responses.

RESUMEN

BACKGROUND: Histiocytic sarcoma (HS) is a rare but highly aggressive disease. The cancer-specific survival of patients with HS is short and only limited response to conventional chemotherapy or radiation therapy is seen. Some data from single case reports have suggested efficacy for high-dose chemotherapy and autologous/allogeneic stem cell transplantation. CASE REPORT: We report on 4 cases of HS, and demonstrate that different druggable receptors are expressed on HS. Using immunohistochemistry, we detected the expression of platelet-derived growth factor receptor, vascular endothelial growth factor receptor and epidermal growth factor receptor, which are all well-known targets for novel targeted agents. Based on the marker profile, different novel targeted therapies including imatinib, sorafenib and bevacizumab were applied to the patients. We observed a varying clinical course for each patient. CONCLUSION: In our case series, we demonstrated that different receptors, which represent potential targets for novel drugs, are expressed on HS tumor cells. For a definitive assessment of the efficacy of these agents a prospective case study of a larger number of patients should be performed.

RESUMEN

Several prognostic factors for the outcome after allogeneic hematopoietic stem-cell transplant (HSCT) from matched unrelated donors have been postulated from registry data; however, data from randomized trials are lacking. We present analyses on the effects of patient-related, donor-related, and treatment-related prognostic factors on acute GVHD (aGVHD), chronic GVHD (cGVHD), relapse, nonrelapse mortality (NRM), disease-free survival (DFS), and overall survival (OS) in a randomized, multicenter, open-label, phase III trial comparing standard graft-versus-host-disease (GVHD) prophylaxis with and without pretransplantation ATG-Fresenius (ATG-F) in 201 adult patients receiving myeloablative conditioning before HSCT from HLA-A, HLA-B antigen, HLA-DRB1, HLA-DQB1 allele matched unrelated donors. High-resolution testing (allele) of HLA-A, HLA-B, and HLA-C were obtained after study closure, and the impact of an HLA 10/10 4-digit mismatch on outcome and on the treatment effect of ATG-F versus control investigated. Advanced disease was a negative factor for relapse, DFS, and OS. Donor age ≥40 adversely affected the risk of aGVHD III-IV, extensive cGVHD, and OS. Younger donors are to be preferred in unrelated donor transplantation. Advanced disease patients need special precautions to improve outcome. The degree of mismatch had no major influence on the positive effect of ATG-F on the reduction of aGVHD and cGVHD.

RESUMEN

OBJECTIVES: Fulfilment of host factors defined by the revised European Organization for the Research and Treatment of Cancer/Mycoses Study Group (EORTC/MSG) criteria is required for establishing the diagnosis of possible or probable invasive fungal infection (IFI). This case-control study evaluates EORTC/MSG host factors among patients with haematological malignancies. METHODS: Fifty-eight patients with haematological malignancies who developed probable (n = 38) or proven (n = 20) IFI over a 5 year period were retrospectively evaluated regarding EORTC/MSG host factors. Results were compared with those obtained from patients with haematological malignancies who did not develop IFI (116 patients who received systemic antifungal prophylaxis or empirical therapy and 116 patients who did not; all data collected in 2010). RESULTS: Fourteen patients had invasive yeast infection and 44 patients had invasive mould infection (IMI). Prolonged neutropenia (35/58, 60% versus 29/116, 25%), prolonged systemic corticosteroid (cut-off 21 days: 13/58, 22% versus 6/116, 5%; cut-off 14 days: 18/58, 31% versus 9/116, 8%) and T cell suppressive therapy (35/44, 80% versus 69/116, 59%) were significantly associated with development of IFI/IMI in our cohort. Previous allogeneic stem cell transplantation (SCT; >6 months prior to episode) was not significantly associated with development of IMI (8/44, 18% versus 22/116, 19%), while recent SCT (<6 months prior to episode) was (11/44, 25% versus 12/116, 10%). CONCLUSIONS: We conclude that host factors according to revised EORTC/MSG criteria were significantly associated with the development of IFI/IMI in our patients. Previous allogeneic SCT was not a predisposing host factor for the development of IMI. Concerning prolonged corticosteroid treatment, a cut-off of 14 days seems preferable to the proposed cut-off.

RESUMEN

Immune Thrombocytopenia (ITP) is a rare and - in most patients - mild disease, but might be associated with severe or even life-threatening bleeding complications. The treatment of ITP has partly changed in recent years, due to new therapeutic options. International guidelines changed accordingly. This consensus statement by the Austrian Society of Hematology and Oncology (OEGHO) is not a new evaluation of the current evidence, but rather tries to discuss the available international guidelines and adapt them to the situation in Austria. The subject is primary ITP in adults only. Classification, epidemiology, clinical presentation and diagnostics of ITP, and especially the management of this disease, are discussed in detail. This includes current aspects of first, second, and third line therapies, splenectomy with its indications and contraindications, and the use of new therapeutic options like thrombopoetin receptor agonists (TRA).
