[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 91.2% patients with low early lethality of 5.5%. Postremission lethality fell to 3.7% versus previous studies (22%). Overall 2-year survival and recurrence-free survival reached 77.6 and 78.4%, respectively. Detection of any chromosomic aberrations significantly affected recurrence-free survival: 74 vs 100% in patients with normal karyotype. CONCLUSION: Protocol All-2009 demonstrates high efficacy in moderate toxicity and good reproducibility in any hematologic center.
