The prognostic value of additional copies of 1q21 in multiple myeloma depends on the primary genetic event.

Hyperdiploidy (HRD) and specific immunoglobulin heavy locus (IGH) translocations are primary chromosomal abnormalities (CA) in multiple myeloma (MM). In this retrospective study of 794 MM patients we aimed to investigate clinical features and common CA including gain(1q) in separate subgroups defined by primary CA. In the entire group, we confirmed that gain(1q) was associated with short time to next treatment and adverse overall survival (OS).

Austrian recommendations for the management of polycythemia vera.

Polycythemia vera (PV) is a clonal disease arising from hematopoietic stem cells. Erythrocytosis is the hallmark of the disease but leukocytosis, thrombocytosis and splenomegaly may also be present. Thromboembolic complications occur in about 20% of patients.

Impact of white blood cells on thrombotic risk in patients with optimized platelet count in essential thrombocythemia.

Objectives: Risk of thrombosis is significantly enhanced by both elevated platelet (PLT) and white blood cell (WBC) counts according to a retrospective analysis of a large anagrelide registry in thrombocythemic MPN patients. We were interested in the impact of elevated WBC counts on thrombosis risk in patients where PLT counts were reduced below the calculated cutoff of 574.5 G/L by treatment with anagrelide.

Anti-Angiogenics: Their Value in Colorectal Cancer Therapy.

Angiogenesis is a hallmark of cancer and is regulated by a balance of pro- and anti-angiogenic factors; among them, the vascular endothelial growth factor (VEGF) is the key angiogenic factor. VEGF plays an important role in colorectal cancer (CRC) biology, and its inhibition by using bevacizumab, an anti-VEGF antibody, proved for the first time to be effective and became indispensable for the treatment of metastatic CRC (mCRC). Several large phase III studies showed also relevant responses and tolerability of other anti-angiogenic drugs such as ramucirumab, aflibercept, and regorafenib, and led to the approval of these therapeutics.

High IDO-1 expression in tumor endothelial cells is associated with response to immunotherapy in metastatic renal cell carcinoma.

Nivolumab belongs to the standard therapy in the second-line setting of metastatic renal cell carcinoma (mRCC). Although deep and long-lasting responses are seen in some patients, the majority of patients will further progress. PD-L1 is still under critical evaluation as a predictive biomarker.

New insights into sinusoidal obstruction syndrome.

Background: Entry criteria included patients who developed sinusoidal obstruction syndrome (SOS) at a single centre from January 2000 to December 2011. Patients who underwent haemopoietic stem cell transplantation or actinomicyn-based chemotherapy for nephroblastoma were selected. The study group comprised five patients with SOS who were compared with a control group of seven patients without SOS.

Impact of age on efficacy and toxicity of nilotinib in patients with chronic myeloid leukemia in chronic phase: ENEST1st subanalysis.

Purpose: Achievement of deep molecular response with a tyrosine kinase inhibitor in patients with chronic myeloid leukemia (CML) is required to attempt discontinuation of therapy in these patients. The current subanalysis from the Evaluating Nilotinib Efficacy and Safety in Clinical Trials as First-Line Treatment (ENEST1st) study evaluated whether age has an impact on the achievement of deeper molecular responses or safety with frontline nilotinib in patients with CML.

Methods: ENEST1st is an open-label, multicenter, single-arm, prospective study of nilotinib 300 mg twice daily in patients with newly diagnosed CML in chronic phase.

Observational retrospective study of vascular modulator changes during treatment in essential thrombocythemia.

Essential thrombocythemia (ET) patients are at risk of developing thrombotic events. Qualitative platelet (PLT) abnormalities and activation of endothelial cells (ECs) and PLTs are thought to be involved. Microparticles (MPs) can originate from PLTs (PMPs), ECs (EMPs), or red cells (RMPs).

Reduced CD62L Expression on T Cells and Increased Soluble CD62L Levels Predict Molecular Response to Tyrosine Kinase Inhibitor Therapy in Early Chronic-Phase Chronic Myelogenous Leukemia.

Purpose Immunologic surveillance of minimal residual disease in chronic myelogenous leukemia (CML) may be relevant for long-term control or cure of CML. Little is known about immune-modulatory effects of nilotinib in vivo, potentially predicting response to therapy. Patients and Methods A prospective and comprehensive flow cytometry-based immunomonitoring program paralleled the ENEST1st clinical study, investigating 52 nilotinib-naïve patients with chronic-phase CML.

Austrian recommendations for the management of primary myelofibrosis, post-polycythemia vera myelofibrosis and post-essential thrombocythemia myelofibrosis: an expert statement.

The entity "myelofibrosis" represents a subgroup of the Philadelphia chromosome-negative myeloproliferative neoplasms. It comprises primary myelofibrosis, post-polycythemia vera myelofibrosis and post-essential thrombocythemia myelofibrosis. This heterogeneous disease is characterized by clonal myeloproliferation, dysregulated kinase signalling and the abnormal expression of several proinflammatory cytokines.

Targeted Therapy of Colorectal Cancer.

Over the past decades, considerable progress has been made in the management of colorectal cancer (CRC), leading to a significant improvement in overall survival. Although part of this success has been rightly attributed to aggressive surgical management and advances in other adjunct treatments, our understanding of the pathogenesis of CRC and emergence of newer molecular targets for colon cancer has created a powerful impact. In this review article, we will discuss various targeted therapies in the management of metastatic CRC (mCRC).

Platelet gel: a new therapeutic tool with great potential.

Chronic wounds, such as diabetic foot ulcers, represent a serious clinical problem for patients and clinicians. Management of these wounds has a strong economic impact worldwide. Complications resulting from injuries are a frequent cause of morbidity and mortality.

Healing of a soft tissue wound of the neck and jaw osteoradionecrosis using platelet gel.

Aim: Bone osteoradionecrosis is a serious complication of radiation treatment. Current treatment approaches are not curative and treatment response is often poor leading to high social and healthcare costs.

Case Report: We report on the first case of osteoradionecrosis with successful restitutio ab integro by repeated administration of platelet gel (PLT-gel) and surgery in a critically ill patient.

Influence of platelet and white blood cell counts on major thrombosis - analysis from a patient registry in essential thrombocythemia.

Objectives: Although guidelines recommend normalization of platelet counts as an appropriate endpoint for treatment in high-risk essential thrombocythemia (ET), retrospective studies could not prove a correlation of diagnostic platelet counts with an increased thrombotic rate. There is, however, an increasing evidence that leukocytosis is an important risk factor for arterial thrombosis in myeloproliferative neoplasms.

Methods: This study considers the Austrian cohort of a European registry regarding the platelet-lowering therapeutic anagrelide.

Routine Use of Bendamustine in Patients with Chronic Lymphocytic Leukemia: An Observational Study.

Bendamustine is an established treatment option in chronic lymphocytic leukemia (CLL) and frequently used in Austria and Italy. Therefore, we analyzed 100 unselected, consecutive patients with CLL (treatment-naïve and relapsed/refractory) receiving bendamustine in a real-life setting. Most patients were treated with bendamustine in combination with rituximab (BR).

Anagrelide treatment and cardiovascular monitoring in essential thrombocythemia. A prospective observational study.

In this prospective observational single-center study, 55 patients with essential thrombocythemia who were candidates for second line treatment with anagrelide (ANA) received a preliminary cardiovascular (CV) clinical, instrumental and biochemical evaluation (CV history and symptoms, CV risk factors, blood pressure, heart rate, ECG and ECHO-cardio parameters, Troponin I, NT-proBNP). After this in-depth CV screening, 54 out of 55 patients were deemed to be fit for ANA treatment. Thirty-eight of the 55 patients received ANA treatment for a median of 36 months (range 3-48), and were monitored using the same CV evaluation.

Role of blood cells dynamism on hemostatic complications in low-risk patients with essential thrombocythemia.

Patients with essential thrombocythemia (ET) aged less than 60 years, who have not suffered a previous vascular event (low-risk patients), may develop thrombotic or hemorrhagic events. So far, it has not been possible to identify useful markers capable of predicting which of these patients are more likely to develop an event and therefore who needs to be treated. In the present study, we analysed the relationship between vascular complications and longitudinal blood counts of 136 low-risk ET patients taken over a sustained period of time (blood cells dynamism).

Cost-effectiveness of the sequential application of tyrosine kinase inhibitors for the treatment of chronic myeloid leukemia.

Several tyrosine kinase inhibitors (TKIs) are approved for chronic myeloid leukemia (CML) therapy. We evaluated the long-term cost-effectiveness of seven sequential therapy regimens for CML in Austria. A cost-effectiveness analysis was performed using a state-transition Markov model.

Neoadjuvant chemo-immunotherapy modifies CD4(+)CD25(+) regulatory T cells (Treg) in non-small cell lung cancer (NSCLC) patients.

Background: Regulatory T cells (Treg) are critical for cancer immune evasion; whereas natural killer (NK) cells are central for effective anti-tumor immunity including antibody-induced cellular cytotoxicity (ADCC). The predictive role of Treg levels for clinical response to chemo-immunotherapy in non-small cell lung cancer (NSCLC) as well as therapy-induced Treg changes remain to be defined.

Patients And Methods: The impact of Treg on NK-mediated cetuximab-dependent cellular cytoxicity was tested in vitro.
