The primary endpoint was overall survival (OS).</p><p><strong>Results: </strong>21 patients with metastatic ACC were included. Median overall survival was 23 months. The median free mitotane level per patient was 12% (± 7%), and the majority (88%) was bound to lipoprotein fractions. Several pharmacokinetics measures of total mitotane were related to OS: first level at one month (p = 0.026), mean level (p = 0.055), and area under the curve (AUC) (p = 0.048), with higher exposure associated to longer OS. Free mitotane (not bounded) and mitotane bounded to lipoprotein subfraction added no prognostic values. The relationship between the mitotane level and OS suggested a minimum \"effective\" threshold of 10-15 mg/L or an area under the curve above 100 mg/L/month with no individualized maximum value.</p><p><strong>Conclusion: </strong>This prospective study did not identify any added prognostic value of free mitotane level over the total level. Early total mitotane level measurements (before 3-6 months) were related to OS with a higher and faster exposure related to more prolonged survival.</p>","PeriodicalId":48802,"journal":{"name":"Journal of Endocrinological Investigation","volume":" ","pages":"357-367"},"PeriodicalIF":5.4,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142019274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
