The aim of the study is to find the best approaches to the treatment of infantile hemangiomas (IH). Materials and methods of research: the experience of treatment of pediatric patients with IH of various localization is presented, which was carried out according to the protocol elaborated by the authors. Systemic therapy with propranolol, local therapy, laser therapy were used in the complex of treatment. The age of patients at the beginning of therapy ranged from 1 month up to 4,5 years. Results: in all cases, patients with propranolol treatment showed a quick and stable effect. Even at the time of the selection of the dose of the drug, IH patients began to involute, became paler, less tense. The thickness of the soft tissues in the IH area decreased by 65% compared to the baseline, the number of functioning vessels decreased by 86%. The maximum effect was achieved within the first 6 months from the start of therapy. Clinical case report – a 2,5-year-old child with extensive hemangioma of the right buttock. There was a complex treatment with propranolol, local therapy, laser therapy. The general course of treatment with propranolol was 2 years 8 months. The total number of laser interventions was 6 with the overall effect in the form of maximum regression of residual clinical manifestations of IH. A positive clinical and ultrasound picture was noted, indicating a pronounced involution of IH, and a gradual withdrawal of propranolol was started. Conclusion: the effectiveness of a comprehensive interdisciplinary approach to the treatment of extensive complicated IH was demonstrated with the participation of specialists of various disciplines: pediatricians, cardiologists, surgeons, specialists in functional and ultrasound diagnostics, specialists in laser therapy, endocrinologists in a severe premature baby with a large number of somatic problems. The clinical treatment algorithm developed and implemented for patients with IH makes it possible to avoid more aggressive methods of treatment of this pathology and to improve the quality of life of this category of patients. On the basis on the results obtained, indications for laser therapy with a selective pulsed laser were formulated.

The diagnosis of myeloid tumors is based on a complex approach and causes significant difficulties especially in young children. Morphologic, immunologic, cytogenetic, molecular and biologic data on myeloid sarcoma are presented based on the literature data and own clinical case. Treatment results of myeloid sarcoma (especially in the high risk group) are unsatisfactory and should be improved.

Современные программы по-лихимиотерапии, в основе которых лежит дифферен-цированный риск-адаптированный подход, позволили рассматривать неходжкинские лимфомы (НХЛ), ранее считавшимися фатальными, как потенциально излечи-мые заболевания. Цель настоящей работы -обобщение и анализ результатов лечения НХЛ за 25-летний период. Conclusion.The obtained results permit to conclude that introduction of achievements of oncoimmunology, molecular biology, and cytogenetics will become the basis for further modification of existing treatment options for NHL.

The results of treatment of acute myeloid leukemias (AML) in children remain unsatisfactory. Modern therapeutic programs with hematopoietic stem cell transplantation allow us to get 5-year overall survival rate of 65 % in primary patients. For patients with relapses or refractory AML, 5-year overall survival is about 35 %.This article presents the possibilities of chemotherapy and hematopoietic stem cell transplantation in the treatment of AML. The possibilities of epigenetic, immune, and cellular therapy are presented for pediatric AML. Special attention is paid to targeted drugs that only beginning to be used in the complex therapy of AML.
