Доцетаксел (Таксотер®) высокоэффективен при раке молочной железы, а комбинация доцетаксела с трастузумабом представляет собой безопасную альтернативу антрациклинсодержащим режимам терапии HER-2-позитивной формы заболевания. Доклинические исследования показали синергизм трастузумаба и доцетаксела в отличие от паклитаксела, характеризующегося только аддитивным взаимодействием с трастузумабом.
Несмотря на отсутствие прямых сравнительных рандомизированных исследований, непрямой анализ продемонстрировал более высокую эффективность комбинации доцетаксел/трастузумаб по сравнению с режимом паклитаксел/трастузумаб при метастатическом HER-2+ раке молочной железы. Добавление капецитабина к комбинации доцетаксел/трастузумаб достоверно увеличивало выживаемость без прогрессирования болезни, однако не влияло на частоту ответов и общую выживаемость больных. Добавление карбоплатина к доцетакселу с трастузумабом не улучшало результаты лечения в отличие от комбинации паклитаксел/трастузумаб.
В адъювантной терапии раннего HER-2-позитивного рака молочной железы обоснованно могут использоваться последовательный антрациклинсодержащий режим доксорубицин/циклофосфамид, затем доцетаксел/трастузумаб (АС-ТН) или безантрациклиновая комбинация доцетаксел/карбоплатин/трастузумаб (ТСН), которая характеризуется сравнимой эффективностью и долгосрочной безопасностью при меньшем числе курсов.
Docetaxel (Taxotere®) is a highly effective agent in breast cancer and the combination of docetaxel/trastuzumab may be a safe alternative to anthracycline-based chemotherapy of HER-2-overexpressing breast cancer. Preclinical studies showed the synergism of trastuzumab with docetaxel unlike paclitaxel which is characterized by additive interaction with trastuzumab.
Despite the fact that there are no prospective randomized studies the indirect analysis showed that the docetaxel/trastuzumab combination is more effective than paclitaxel/trastuzumab combination. The addition of capecitabine to the docetaxel/trastuzumab combination increased progression free survival, however it did not show a significant difference in the response rate and overall survival. The addition of carboplatin to the docetaxel/trastuzumab combination did not improve the effectiveness of treatment, but the combination of carboplatin/paclitaxel/trastuzumab was proven to be more effective, than paclitaxel/trastuzumab.
Both treatment regimens (consisting docetaxel plus trastuzumab following doxorubicin and cyclophosphamide or consisting docetaxel, carboplatin and trastuzumab) might be used in adjuvant chemotherapy of patients with HER-2-positive early breast cancer.
Key words: docetaxel (Taxotere®), trastuzumab, breast cancer.
