Prognostic factors and clinical characteristics of patients with newly diagnosed non-secretory multiple myeloma in the era of new drugs in "real-world" study: Experiences of the Polish Myeloma Group.

Background: Non-secretory multiple myeloma (NSMM) accounts for approx. 2-3% of multiple myeloma (MM) cases. Due to the rare occurrence and ineligibility of patients with NSMM to participate in clinical trials, we have limited data on treatment efficacy and the clinical course in these patients.

Therapeutic adherence and assessment of satisfaction patients with multiple myeloma treated with immunomodulatory drugs in a "real-world" study: Experiences of the Polish Myeloma Group.

Introduction: Therapeutic adherence (TA) is one of the most important factors influencing the effectiveness of treatment. Oral anti-cancer drugs are increasingly used to treat malignancy including multiple myeloma (MM). Our study aimed to determine TA of patients with MM treated with IMiDs, to identify TA risk factors, and to determine satisfaction with medical care during the treatment with IMiDs.

Demographic, Hematologic, and Clinical Features of Myelodysplastic Syndrome Patients: Results from the First Polish Myelodysplastic Syndrome Registry.

Epidemiological studies on myelodysplastic syndromes (MDS) in Middle-Eastern Europe are scarce. No data about the demographic, clinical, and laboratory features of Polish MDS patients have been published. The aim of this study was to assess the epidemiological data and toxic exposure of Polish MDS patients and their association with hematological parameters and clinical outcomes.

Immune thrombocytopenia in patients with chronic lymphocytic leukemia treated with cladribine-based regiments or chlorambucil--follow-up of PALG-CLL randomized trials.

Objectives: The relationship between treatments of chronic lymphocytic leukemia (CLL) with cladribine (2-CdA) or chlorambucil and immune thrombocytopenia (IT) has not been yet determined.

Methods: The records of 777 patients in two randomized Polish Adult Leukemia Group (PALG)-CLL programs treated with these agents were retrospectively analyzed.

Results: Immune thrombocytopenia occurred in 55 of 777 (7.

[Immunomodulatory drugs in the treatment of primary systemic light chain amyloidosis].

Primary systemic immunoglobulin light chain amyloidosis (AL.) is an incurable clonal plasma cell disorder in which fragments of Ig light chain are deposited in tissues. High dose melphalan and hematopoietic cell transplantation (SCT) is a preferred technique, but only 20% of patients are eligible.

[Study of subpopulations of lymphocytes in the bone marrow of patients with myelodysplastic syndromes].

Unlabelled: Myelodysplastic syndromes are heterogeneous group of clonal blood disorders. Various abnormalities in the immunoregulation system have been reported in patients with MDS. Most of studies were about lymphocytes in peripheral blood.

Cladribine in a weekly versus daily schedule for untreated active hairy cell leukemia: final report from the Polish Adult Leukemia Group (PALG) of a prospective, randomized, multicenter trial.

Cladribine (2-chlorodeoxyadenosine, 2-CdA) treatment-associated infections may shorten potentially long-term survival in hairy cell leukemia (HCL). In search of the optimal mode of 2-CdA administration, 132 patients with untreated HCL were randomized to receive either standard 5-day 2-CdA protocol or a novel schedule of 6 weekly 2-CdA infusions suggested to be less toxic. Analysis of treatment response confirmed similar complete remission rates, overall response rates, progression-free survival, and overall survival in both 2-CdA protocols.
