[The role of genetic polymorphisms of interleukins in chronic lymphocytic leukemia in patients of different ages].

Chronic lymphocytic leukemia (CLL) is a multifactorial disease, in which development the important role played the cytokine genes, in particular interleukins. This type of leukemia is more common in the elderly. The purpose of the study was to evaluate the association of genetic polymorphisms of interleukin with the development of chronic lymphocytic leukemia among residents of the Central Chernozem region of Russia.

[Clinical associations of genetic variants of interleukins with the formation of chronic lympholeukemia in elderly patients].

We investigated association of polymorphisms of interleukin IA (IL-1A), interleukin 4 (IL-4), interleukin 5 (IL-5), interleukin-8 (1L-8) genes in elderly patients with predisposition to the development of chronic lym,nphocytic leukemia (CLL). Risk factor of chronic lymphocytic leukemia is a genetic variant -590T IL-4 (OR = 1,45) and protective factor -590S IL-4 (OR = 0,68). Genetic markers -590T IL-4 (OR = 2,46), -590TT IL-4 (OR = 6,65) and mix-590TT genotype of IL-4 allele 703S-IL-5 (OR = 6.

[First results of Ph-negative acute lymphoblastic leukemia therapy of adults according to the protocol of Research Group of Russian Hematological Centers ALL-2009].

Aim: To review results of 2-year experience in execution of the protocol on the treatment of adult acute Ph-negative lymphoblastic leukemia ALL-2009.

Material And Methods: Of 111 patients registered in the study from November 2008 to December 2010 the analysis covered 96 patients from 23 hematological centers in 18 towns of the RF.

Results: Treatment according to the Protocol ALL-2009 resulted in achievement of a complete remission in 91.

[Toxicity of different treatment protocols for acute myeloid leukemias in adults: the results of four Russian multicenter studies].

Aim: To comparatively analyze the toxicity of 4 treatment protocols in patients with acute myeloid leukemia (AML), which were used in the Russian multicenter center in 1992 to 2009.

Materials And Methods: The information obtained in 4 Russian multicenter studies conducted in 33 hematology departments of 26 cities and towns of the Russian Federation in 1992 to 2009 was analyzed. Randomization was made in 243 patients with AML (median age 38 years) in 1992-1995, 396 patients (median age 39 years) in 1995-1999, 392 patients (median age 39 years) in 2001-2006, and 137 patients (median age 40 years) in 2006-2009.
