Ингибиторы PARP1 в терапии рака молочной железы. Механизм действия и клиническое применение

Известно, что в настоящее время ингибиторы PARP активно применяются при лечении опухолей женской репродуктивной системы. Было представлено огромное количество исследований, доказывающих эффективность PARP-ингибиторов в терапии BRCA-ассоциированного рака яичников. Установлено, что мутации в генах BRCA1 и BRCA2 характерны и для рака молочной железы (РМЖ). Однако ингибиторы PARP редко применяются в клинической практике при лечении РМЖ. На данный момент только олапариб стал первым ингибитором PARP, одобренным для лечения метастатического РМЖ. В представленном обзоре приведены данные за последние 10 лет, показывающие высокую эффективность PARP-ингибиторов при лечении злокачественных новообразований молочной железы. В 7 из 28 проанализированных исследований положительные результаты были достигнуты при комбинированном лечении химиотерапевтическими препаратами и ингибиторами PARP. Так, например, в 2 работах при лечении BRCA-ассоциированного РМЖ ответ на терапию у пациенток составил 72,5–73,2 %. Таким образом, ингибиторы PARP представляют большой интерес и имеют практическую ценность при лечении больных РМЖ.
