However, the challenge of achieving efficient or sustained therapeutic benefits underscores the critical imperative to optimize ICB strategies. This review elucidates the pivotal role of predictive biomarkers in optimizing precision ICB therapy, deciphering the intricate dynamics associated with the response heterogeneity. Furthermore, it critically examines the application of nanotechnology-driven drug delivery as a promising avenue to amplify ICB efficacy, facilitating controlled and targeted drug release. Recognizing the comprehensive and dynamic interplay among tumor cells, immune cells, and stromal cells has catalyzed the transformative advances in reverse translational research. This approach enables researchers to gain insights into the underlying mechanisms of ICB therapy, therapeutic responses, and resistance mechanisms. The convergence of predictive biomarkers, revolutionary nanotechnology, and reverse translational research emerges as an indispensable focal point, propelling the frontiers of precision oncology within the complex landscape of ICB therapy.","PeriodicalId":54687,"journal":{"name":"Oncologie","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140232505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
