Открытие в 80-х годах прошлого столетия рецептора эпидермального фактора роста 2-го типа (Her-2/neu, ErbB2) как терапевтической мишени открыло путь к созданию целой группы препаратов таргетного (целенаправленного) действия при РМЖ с гиперэкспрессией/амплификацией Her-2/neu. Одним из таких препаратов является трастузумаб – моноклональное антитело, связывающееся с экстрацеллюлярным доменом рецептора Her-2/neu. Трастузумаб уже широко используется в повседневной практике как при раннем, так и при метастатическом раке молочной железы. В настоящем обзоре наряду с современными аспектами применения трастузумаба рассмотрены некоторые нерешенные вопросы, в том числе касающиеся механизмов действия и резистентности.
The discovery of epidermal growth factor receptor-2 (Her-2/neu, ErbB2) as a therapeutic target in the 1980s has opened up the way to the design of a whole group of targeted (goal-oriented) drugs against breast cancer with Her-2/neu hyperexpression/amplification. One of these drugs is trastuzumab, a monoclonal antibody that binds to the extracellular domain of the Her-2/neu receptor. Trastuzumab has already been routine practice to treat both early and metastatic breast cancer. Along with the current aspects of the use of trastuzumab, this review considers some unsolved problems, including those relating to the mechanisms of its action and resistance.
Key words: breast cancer, Her-2/neu hyperexpression/amplification, trastuzumab.
