Фулвестрант представляет собой новый класс лекарственных препаратов для эндокринной терапии рака молочной железы. Уникальный механизм действия – деградация рецепторов эстрогенов – позволяет не только применять препарат в качестве монотерапии гормонозависимого рака молочной железы, но и создавать необычные комбинации противоопухолевых препаратов с его включением. Изучение фулвестранта активно продолжается. В последнее время опубликована целая серия интересных данных по лечению диссеминированного гормонозависимого рака молочной железы. Особый интерес представляет комбинация фулвестранта и анастрозола, опровергающая существующую тактику последовательного применения препаратов для эндокринной терапии рака молочной железы. Не меньше интригуют экспериментальные данные о возможном применении препарата в комбинации с цитостатиками, а также о применении его при других злокачественных опухолях, где никогда ранее эндокринная терапия не применялась. В статье будут представлены последние данные, касающиеся препарата фулвестрант, в том числе алгоритм его применения и перспективные направления развития.
Fulvestrant is a new drug for endocrine therapy of breast cancer. Its unique mechanism of estrogen receptor degradation makes it possible not only to use the agent as monotherapy for hormone-dependent breast cancer, but also to design unusual antitumor combinations with its inclusion.
Investigations of fulvestrant are being actively continued. A large set of interesting data on the treatment of disseminated hormone-dependent breast cancer has been recently published. The fulvestrant-and-anastrozole combination that dispels the existing tactics in the successive use of medications for endocrine therapy of breast cancer is of specific interest. But no less intriguing is experimental evidence that the drug may be used in combination with cytostatics and in other malignant tumors for which endocrine therapy has never been used. The paper gives the latest data on fulvestrant, including its use algorithm and promising development directions.
