The results of randomized clinical trials and over 5-years accumulated international experience in the use of CDK4/6 inhibitors in real clinical practice prove that the use of combinations with CDK4/6 inhibitors can achieve significant efficacy results and increase the survival rates when prescribed in 1 and 2 lines of treatment.</p><p>In this paper, we present the results of a survey conducted in July–October 2019 among 48 oncologists in Moscow, that were asked to choose, in their opinion, the most preferable patient’s profile and molecular and biological features of hormone-positive HER2-negative advanced breast cancer, in which the use of combination therapy with CDK4/6 inhibitors will provide the greatest benefit.</p><p>Conflict of interest.

Результаты рандомизированных клинических исследований и накопленный за 5 лет международный опыт применения ингибиторов CDK4/6 в реальной клинической практике доказывают, что использование комбинированной терапии с препаратами этого класса позволяет достигнуть значимых результатов лечения и продлить жизнь пациенток именно при назначении в 1-й и 2-й линиях лечения. В данной работе мы представляем результаты опроса, проведенного в июле–октябре 2019 г., в котором 48 онкологам Москвы предлагалось выбрать наиболее подходящие, на их взгляд, клинические характеристики пациенток и молекулярно-биологические особенности гормоноположительного HER2-отрицательного распространенного рака молочной железы, при которых применение комбинированной терапии с ингибиторами CDK4/6 даст наибольшую пользу.</p><p>Конфликт интересов.
