Personalized drug combinations to overcome trastuzumab resistance in HER2-positive breast cancer
Cet article passe en revue les travaux récents sur les combinaisons de traitements susceptibles d'être mis en œuvre pour surmonter l'apparition d'une résistance au trastuzumab chez les patientes atteintes d'un cancer du sein HER2+ métastatique
HER2-positive (HER2 +) breast cancer accounts for 18%–20% of all breast cancer cases and has the second poorest prognosis among breast cancer subtypes. Trastuzumab, the first Food and Drug Administration-approved targeted therapy for breast cancer, established the era of personalized treatment for HER2 + metastatic disease. It is well tolerated and improves overall survival and time-to-disease progression; with chemotherapy, it is part of the standard of care for patients with HER2 + metastatic disease. However, many patients do not benefit from it because of resistance. Substantial research has been performed to understand the mechanism of trastuzumab resistance and develop combination strategies to overcome the resistance. In this review, we provide insight into the current pipeline of drugs used in combination with trastuzumab and the degree to which these combinations have been evaluated, especially in patients who have experienced disease progression on trastuzumab. We conclude with a discussion of the current challenges and future therapeutic approaches to trastuzumab-based combination therapy.
