Раннее назначение эпоэтина-β предотвращает развитие тяжелой анемии у больных раком легкого, получающих химиотерапию на основе препаратов платины: анализ подгруппы клинического исследования NeoPrevent
Исследование NeoPrevent показало, что раннее назначение эпоэтина-β может предотвратить развитие тяжелой анемии у пациентов с солидными опухолями, получающих химиотерапию на основе препаратов платины. Раннее назначение эпоэтина-β целесообразно у больных раком легкого, поскольку развитие анемии (во многих случаях тяжелой) часто сопутствует этому заболеванию. Целью настоящего исследования было определение эффективности и безопасности эпоэтина-β при назначении его больным раком легкого в рамках исследования NeoPrevent. В исследование включали пациентов, у которых исходный уровень гемоглобина был ≤13 г/дл (мужчины) и ≤12 г/дл (женщины) или снизился до этих значений в ходе проведения химиотерапии на основе препаратов платины. Пациенты получали эпоэтин-β 3 раза в неделю в дозе 150 МЕ/кг до 4 нед после последнего цикла химиотерапии. Ответ на профилактическую терапию анемии определяли путем выявления доли пациентов с повышением уровня гемоглобина (>1 г/дл) и пациентов, у которых уровень гемоглобина не отклонялся от первоначального значения (±1 г/дл). Качество жизни (КЖ) оценивали с помощью линейной аналоговой шкалы. В исследование NeoPrevent были включены 255 пациентов. В статье представлены результаты анализа данных 102 больных раком легкого (немелкоклеточный рак легкого – 64%, мелкоклеточный рак легкого – 36%). Общая частота ответа на профилактическую терапию составила 90% (у 60% пациентов наблюдалось повышение уровня гемоглобина, у 30% уровень гемоглобина удерживался на первоначальном уровне). Переливание крови потребовалось только 9% пациентов. Достоверное улучшение КЖ было отмечено у пациентов с Hb-ответом (p<0,01), у остальных пациентов изменения КЧ не произошло (p≥0,578). Эпоэтин-β продемонстрировал эффективность при профилактике тяжелой анемии у больных раком легкого, получающих химиотерапию на основе препаратов платины.
