Bortezomib-based therapy for newly diagnosed multiple myeloma patients ineligible for autologous stem cell transplantation: Czech Registry Data.

Objectives: This study compared the use of bortezomib in different combination regimens in newly diagnosed multiple myeloma (NDMM) patients who were transplant ineligible.

Patients And Methods: We analyzed data from the Registry of Monoclonal Gammopathies (RMG) of the Czech Myeloma Group (CMG) to provide real-world evidence of outcome for 794 newly diagnosed MM transplant ineligible patients. The most frequently used regimen was VCd (bortezomib-cyclophosphamide-dexamethasone) (47.

Deciphering the complex circulating immune cell microenvironment in chronic lymphocytic leukaemia using patient similarity networks.

The tissue microenvironment in chronic lymphocytic leukaemia (CLL) plays a key role in the pathogenesis of CLL, but the complex blood microenvironment in CLL has not yet been fully characterised. Therefore, immunophenotyping of circulating immune cells in 244 CLL patients and 52 healthy controls was performed using flow cytometry and analysed by multivariate Patient Similarity Networks (PSNs). Our study revealed high inter-individual heterogeneity in the distribution and activation of bystander immune cells in CLL, depending on the bulk of the CLL cells.

Quantitative assessment of informative immunophenotypic markers increases the diagnostic value of immunophenotyping in mature CD5-positive B-cell neoplasms.

Background: The data on the clinical utility of the quantitative assessment of immunophenotypes in distinguishing mature CD5-positive B-cell neoplasms is limited. The study aim was to assess the diagnostic value of the quantitative assessment of a panel of 18 markers and to identify the most informative ones.

Methods: The immunophenotype of the neoplastic population was determined in diagnostic specimens from 188 patients.

A first Czech analysis of 1887 cases with monoclonal gammopathy of undetermined significance.

Introduction: Monoclonal gammopathy of undetermined significance (MGUS) is a premalignant condition with a risk of malignant conversion.

Patients And Methods: With the aim to estimate the cumulative risk MGUS progression to hematologic malignancies, we analyzed a nationwide population-based cohort of 1887 MGUS patients from the Czech Registry of Monoclonal Gammopathies (RMG) between 2007 and 2013.

Results: During the follow-up period (median 4 years; range 0.

10 years of experience with thalidomide in multiple myeloma patients: report of the Czech Myeloma Group.

We analyzed 1156 multiple myeloma (MM) patients treated with thalidomide. The overall response rate was 63.6%, with complete remission in 13.

Polymorphism G-308A in the promoter of the tumor necrosis factor-α gene and its association with the risk of venous thromboembolism.

The main abnormalities associated with the increased risk of venous thrombosis are the inherited deficiencies of antithrombin, protein C, protein S, the point mutations known as factor V Leiden and factor II G20210A. The association of other specific genes with thrombotic risk is less known. G-308A polymorphism in the promoter area of the gene coding for tumor necrosis factor α (TNF-α) is associated with an increased transcription activity of this gene, increased TNF-α production and subsequent predisposition to some illnesses.

Synchronous second primary neoplasms detected by initial staging F-18 FDG PET/CT examination in patients with non-Hodgkin lymphoma.

Purpose Of The Report: Cases of synchronous non-Hodgkin lymphoma (NHL) and second primary carcinoma in previously untreated immunocompetent patients are relatively rare. The aim of this part of our prospective study was to a revealed 2-F-18 fluoro-2-deoxy-D-glucose (F-18 FDG) positron emission tomography (PET)-positive lesion in an extranodal organ suggestive of second primary neoplasm in newly diagnosed NHL patients.

Materials And Methods: A total of 209 patients with NHL underwent initial staging F-18 FDG PET/computed tomography (CT).

T-cell gamma/delta hepatosplenic lymphoma - prolonged remission induced by aggressive first line treatment.

T-cell gamma/delta hepatosplenic lymphoma is a primary extranodal lymphoma, distinct from other T/LGL lymphomas. The clinical course is aggressive, and despite use of the multiagent chemotherapy and young age of the patients, the median survival is less than 1 year. Curability of this disease is still uncertain.
