The 5-year OS rates of the three induction groups were 96%, 80%, and 31%, respectively. None of the 48 patients who underwent ATO + ATRA + stDNR induction relapsed, whereas 9.4% (5/53) patients in ATO + ATRA + ldDNR group relapsed, and the relapse rate was 30.0% (3/10) in ATO + others group (<i>p</i> = 0.003). The survival advantage of ATO + ATRA + stDNR was demonstrated by a Cox regression (hazard ratio (HR) = 5.079, 95% CI: 1.071-24.079). WBC ⩾100 × 10⁹/L was correlated with an inferior OS (HR = 3.402, 95% CI: 1.359-8.518).</p><p><strong>Conclusion: </strong>Compared with low-dose anthracycline, standard-dose anthracycline combined with ATO and ATRA dual induction resulted in excellent outcome for high-risk APL patients.</p>","PeriodicalId":23048,"journal":{"name":"Therapeutic Advances in Hematology","volume":"15 ","pages":"20406207241299699"},"PeriodicalIF":3.4,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11577467/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142682884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
