Patients taking any statins (10.8%) and those taking high-intensity statins (15.8%) had higher rates of gastrointestinal irAEs than patients not taking statins (8.7%; P=0.046 and 0.006, respectively). Compared with the nonstatin treatments, statin use was associated with improved overall survival for patients taking PD-1 inhibitors (P<0.001) and for patients with (P=0.021) and without (P<0.001) gastrointestinal irAEs.</p><p><strong>Conclusions: </strong>Synergism of statins with PD-1 and PD-L1 inhibitors continues to be a developing field of interest. Our data demonstrate the survival benefit of combination therapy with PD-1 and/or PD-L1 inhibitors and statins, warranting further investigation.</p>","PeriodicalId":50812,"journal":{"name":"American Journal of Clinical Oncology-Cancer Clinical Trials","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142548777","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}
