Cancer is a major risk of public health both globally, regionally and nationally. In the republic of Moldova (RM) cancer represents the same paternity specific to the globally one and is ranked second among the leading causes of death of the population [1, 2]. It also occupied the second-highest position among causes of mortality in children up to 15 years of age [3]. According to dates from the National Health Management Center of the ministry of Health, the mortality structure according to the causes of death actually did not change during the period 2012-2017: most deaths are due to the diseases of the circulatory system, followed by tumors, digestive diseases, accidents, intoxications and trauma, diseases of the respiratory system [4]. Hemoblastoses are malignant tumors that develop from hematopoetic tissue cells [5]. We differ in leukemia and lymphoma [6]. These two groups of hemoblastoses differ in clinical progression, treatment, prognosis and morbidity, mortality. Childhood hemoblastses accounts for 50% of all malignant tumors at this age, and acute leukemia accounts for one third of all malignant tumors (30 cases per 1 million inhabitants) with maximum development at 2-5 years of age [7].
