РЕФЕРАТ

Возможность наблюдения без лечения у пациентов с хроническим миелолейкозом (ХМЛ) в эру ингибиторов тирозинкиназ (ИТК) остается актуальным вопросом. В клинических исследованиях по отмене ИТК при стабильном глубоком молекулярном ответе показана вероятность сохранения молекулярной ремиссии у 40–60 % больных. Сохранение ремиссии без лечения (РБЛ) даже при персистировании остаточных лейкозных клеток свидетельствует о том, что существуют особые, биологически обусловленные механизмы контроля пролиферации опухолевых клеток, не зависящие от BCR-ABL-киназной активности. Поиск факторов, которые определяют различия кинетики остаточного лейкозного клона после отмены ИТК, — важная задача для понимания основ РБЛ как нового биологического явления. В обзоре представлены сведения мировой литературы, касающиеся изучения иммунных, генетических и других биологических механизмов, лежащих в основе контроля минимальной остаточной болезни после отмены ИТК у больных ХМЛ.

Ключевые слова: хронический миелолейкоз, ингибиторы тирозинкиназ, ремиссия без лечения, глубокий молекулярный ответ, минимальная остаточная болезнь.
