Одним из направлений повышения эффективности терапии данного типа новообразований служит переход от групповой к персонифицированной терапии.ЦельРазработать и апробировать вариант метода оценки in vitro чувствительности клеток нейроэпителиальных опухолей к химиопрепаратам и сопоставить характеристики данного метода с другими методами определения in vitro химиочувствительности клеток различных по гистологическому типу новообразований.Материалы и методыНа примере первичных культур клеток интракраниальных опухолей детей (90) в возрасте 7,4±1,1 лет разработан и апробирован упрощенный вариант анализа их индивидуальной чувствительности и резистивности к химиотерапевтическим средствам. Его сущность сводится к подсчету в камере Горяева пропорции погибших (окрашивающихся трипановым синим) и выживших (прозрачных) клеток после их односуточного экспонирования с цитостатическими препаратами в дозах, близких к 50%-м летальным.РезультатыНа основании градации индексов цитотоксичности химиопрепаратов ex vivo и оценки результатов терапии пациентов цитостатическими средствами по принятым формулам были произведены расчеты чувствительности (67,2%), специфичности (56,8%), положительной (87,3%) и отрицательной (26,6%) прогностической ценности способа.ВыводыРезультаты оказались сопоставимыми с таковыми иных более трудоемких методов, открывая перспективу применения данного варианта при некотором его техническом усовершенствовании.</p></abstract><trans-abstract xml:lang="en"><p>BackgroundNeuroepithelial tumors are the most intractable to other types of cancer, especially in children and adolescents. One of the ways of increasing the efficacy of this type of tumors, the transition from group serves to a personalized therapy.ObjectiveDevelop and test version of the method in vitro evaluation of the sensitivity of neuroepithelial tumors cells to chemotherapy drugs and compare the characteristics of this method with other methods of determining the in vitro chemosensitivity of cells of different histological types of tumors.Subjects and methodsFor example, the primary cell cultures of intracranial tumors (ependymomas, anaplastic astrocytoma, glioblastoma, neuroblastoma, medulloblastoma, primitive neuroectodermal and atypical rhabdoid teratoid neoplasias) children (90) at the age 7,4 ± 1,1 years, developed and tested uproschnny option the analysis of their individual susceptibility and resistivity to chemotherapeutic drugs. Its essence consist of down to counting chamber Goryaeva proportion of dead (stained with trypan blue) and survivors (transparent) cells after their one-day exposure to cytotoxic drugs in doses that are close to the 50% lethal.ResultsBased on the gradation index of cytotoxicity of chemotherapeutic drugs and ex vivo evaluation of patients with cytotoxic drugs Supervision, according to accepted formulas were made calculations of sensitivity (67.2%), specificity (56.8%), positive (87.3%) and negative (26.6%) predictive value method.ConclusionThe results were comparable to those of other more laborintensive methods, opening up the prospect of using this option for some of its technical development</p></trans-abstract><kwd-group xml:lang="ru"><kwd>химиочувствительность и резистентность клеток</kwd><kwd>нейроэпителиальные опухоли</kwd><kwd>прогнозирование терапевтического ответа</kwd><kwd>персонифицированная терапия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chemosensitivity and resistance cell neuroepithelial tumor therapeutic response prediction</kwd><kwd>individual therapy</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Апшкалне Д.
