Авастин (Бевацизумаб) – первый антиангиогенный препарат, прочно вошедший в клиническую практику при ряде онкологических заболеваний. В работе приводятся промежуточные результаты наблюдательного нерандомизированного исследования в ежедневной клинической практике, целью которого является оценка переносимости и эффективности химиотерапии (ХТ) в комбинации с Авастином у больных HER2-негативным раком молочной железы (РМЖ). В исследование включены 20 больных РМЖ (4 – местно-распространенным, 16 – метастатическим) в возрасте от 34 до 66 лет (средний возраст 49,2 года). Авастин вводили в дозе 10 мг/кг в виде внутривенной инфузии 1 раз в 3 нед в комбинации с ХТ. Всего проведено 154 курса (от 2 до 20; медиана – 9). Полные регрессии отмечены в 3 (15%) наблюдениях, частичные – в 5 (25%), стабилизация – у 9 (45%) больных, прогрессирование выявлено у 3 (15%) пациенток. Таким образом, общая эффективность лечения составила 40%. Медиана выживаемости без прогрессирования (ВБП) в группе метастатического РМЖ составила 10 мес. Характерные для Авастина нежелательные явления, такие как гипертензия, протеинурия, были умеренно выражены и встречались редко: соответственно, у 3 (15,0%) больных в 3,2% курсов и у 2 (10,0%) – в 2% курсов. Ни одной пациентке лечение не было отменено из-за токсичности, обусловленной Авастином.
Заключение: Авастин в комбинации с ХТ для лечения РМЖ позволяет достичь высоких показателей объективного эффекта и ВБП.
Avastin (Bevacizumab) is the first antiangiogenic drug that has become the clinical practice to treat a number of cancers. The paper gives the intermediate results of an observational nonrandomized trial in daily clinical practice, the purpose of which is to evaluate the tolerability and efficiency of chemotherapy (CT) in combination with Avastin in patients with HER2-negative breast cancer (BC). The investigation enrolled 20 patients with BC, including 4 and 16 with locally advanced and metastatic BC, respectively, at the age of 34 to 66 years (mean age 49,2 years). Avastin was administered in a dose of 10 mg/kg as intravenous infusion once three weeks in combination with CT. A total of 154 courses (from 2 to 20; median 9) were performed. Complete and partial regressions were observed in 3 (15%) and 5 (25%) cases, respectively; stabilization was seen in 9 (45%) patients and progression was in 3 (15%). Thus, the total efficiency of treatment was 40%. In the metastatic BC group, the median progression-free survival (PFS) was 10 months. Avastin-related adverse events, such as hypertension and proteinuria, were moderate and rare: in 3 (15,0%) and 2 (10%) patients in 3,2 and 2% of the courses, respectively. Treatment was discontinued because of Avastin-induced toxicity in none of the patients.
Conclusion. Avastin in combination with CT in the treatment of BC allows high objective effect and PFS rates to be achieved.
Key words: breast cancer, triple negative breast cancer, Avastin, chemotherapy, objective response, progression-free survival.
