Correct diagnosis of clinically distinct subgroups of aggressive mature B-cell lymphomas is crucial for the choice of adequate treatment. Currently, the identification of DLBCL subtype depends on a combination of morphologic, immunophenotypic, and cytogenetic/molecular features. The classification covers the most common unspecified variant of DLBCL, also referred to as "not otherwise specified" (NOS), and a number of other rare forms. Over the past two decades, DLBCL NOS which accounts for more than 80% of all cases, has been the subject of a growing number of molecular studies that have identified prognostic factors that are being actively introduced into real-world clinical practice. Only the integration of morphological, immunohistochemical and molecular features of DLBCL will lead to the achievement of the long-term goal of curing the majority of patients with minimal or no toxic manifestations with the aid of personalized healthcare.</p></abstract><trans-abstract xml:lang="ru"><p>Диффузная В-клеточная крупноклеточная лимфома (ДВККЛ) является наиболее распространенным вариантом неходжкинских лимфом, и на ее долю приходится примерно 1/3 всех неходжкинских лимфом в западных странах и около 40% В-клеточных опухолей во всем мире. Правильный диагноз клинически различающихся подгрупп агрессивных зрелоклеточных В-клеточных лимфом имеет решающее значение для выбора адекватного лечения. В настоящее время идентификация варианта ДВККЛ зависит от сочетания морфологических, иммунофенотипических и цитогенетических/молекулярных особенностей. Классификация охватывает наиболее распространенный, неспецифицированный вариант ДВККЛ, также называемый как «не указано иное» (NOS), и ряд других редких форм. За последние два десятилетия ДВККЛ NOS, на долю которой приходится более 80% всех случаев, стала объектом растущего числа молекулярных исследований, которые позволили идентифицировать прогностические факторы, активно внедряемые в реальную клиническую практику. Только объединение морфологических, иммуногистохимических и молекулярных особенностей ДВККЛ приведет к достижению долгосрочной цели использования персонифицированных методов, способных излечить большинство пациентов, с минимальными токсическими проявлениями или вообще без них.</p></trans-abstract><kwd-group xml:lang="en"><kwd>diffuse large B-cell lymphoma</kwd><kwd>gene expression profiling</kwd><kwd>next generation sequencing</kwd><kwd>classification</kwd><kwd>diagnosis</kwd><kwd>prognosis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>диффузная В-клеточная крупноклеточная лимфома</kwd><kwd>профилирование экспрессии генов</kwd><kwd>секвенирование следующего поколения</kwd><kwd>классификация</kwd><kwd>диагностика</kwd><kwd>прогноз</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Sarkozy C, Coiffier B.
