With the advancement of immunotherapy, an increasing number of ICIs have been developed or are in clinical trial stages. However, drug resistance and immune-related adverse events (irAEs) associated with ICIs have limited the clinical application of immunotherapy in OSCC, and the optimal drug regimen for ICIs and the optimal duration of ICIs administration also deserves to be further discussed. New therapeutic regimens and drug delivery technologies are key to promoting the further development of ICIs. This article elucidates the mechanism of ICIs’ action and presents a review of their clinical applications and current development status in OSCC. Additionally, it summarizes the current challenges and outlines future research directions for ICIs therapy, with the aim of offering fresh insights to researchers.","PeriodicalId":54687,"journal":{"name":"Oncologie","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141358070","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}

As the tumor grew, our clinical team creatively performed ultrasound-guided radiofrequency ablation combined with puncture and aspiration at 28 weeks of gestation, followed by puncture and aspiration only at 32 weeks of gestation, to reduce the tumor volume and control its growth rate.
