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.

G-CSF administered in time-sequenced setting during remission induction and consolidation therapy of adult acute lymphoblastic leukemia has beneficial influence on early recovery and possibly improves long-term outcome: a randomized multicenter study.

Sixty-four untreated adult acute lymphoblastic leukemia (ALL) patients were randomized to receive chemotherapy alone, n = 31 or chemotherapy and granulocyte colony stimulating factor (G-CSF), n = 33. During induction patients received G-CSF for 5 days between four weekly Epirubicin+Vcr administrations, starting 36 h after each application and finishing 48 h before the next one with the intention to possibly generate a cell cycle dependent protection of normal hematopoietic progenitors and to stimulate granulopoiesis. The complete remission (CR) rate equaled 94% in the G-CSF group and 87% in controls.

2-Chlorodeoxyadenosine treatment in non-Hodgkin's lymphoma and B-cell chronic lymphocytic leukemia resistant to conventional chemotherapy: results of a multicentric experience. International Society for Chemo-Immunotherapy.

Among the purine analogs, 2-chlorodeoxyadenosine (2-CDA) is particularly effective for the treatment of hairy cell leukemia and Waldemstrom's macroglobulinemia. Both efficacy and toxicity of 2-CDA were evaluated in previously treated patients affected with chronic lymphoproliferative disorders such as low-grade non-Hodgkin's lymphoma (NHL) and B-cell chronic lymphocytic leukemia (CLL). Thirty cases, mainly refractory, 16 affected with CLL, were included from six centers of the International Society for Chemo-Immunotherapy (IGCI).

[Primary forms of extralymphatic non-Hodgkin's lymphoma].

In 1981-1990, 584 patients with non-Hodgkin malignant lymphoma, 209 women and 375 men, aged between 17 and 75 years, were treated at the I Department of Medicine and Department of Hematology, Silesian Medical Academy in Katowice. In this group the primary localization outside lymph nodes was seen in 26 patients (9 women and 17 men), i.e.

[Results of induction treatment with idarubicin for acute nonlymphoblastic leukemia in adults].

Fifty six adult acute nonlymphoblastic leukemia patients were randomised in 1993 year according to Polish Acute Leukemia Group (PALG) into prospective, cooperative trial with the same prognostic factors distribution. The results of induction treatment using idarubicin on days 1, 3, 5 plus arabinoside cytosine 1-7/10 plus etoposide 1-5 (ICE7/10) vs. daunorubicin on days 1-3 plus Ara-C 1-7/10 with additional HD Ara-C in case of not sufficient cytoreduction in 6th day's bone marrow biopsy (3+7/+/-HD) and etoposide in M4-5 subtype are comparable (63 vs.
