Efficacy Analysis of MAC Regimen as Salvage Treatment Protocol for Acute Myeloid Leukemia Patients Older Than 55 Years / 中国实验血液学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of MAC regimen in the treatment of acute myeloid leukemia(AML) patients older than 55 years.</p><p><b>METHODS</b>A total of 33 relapsed or non-remission AML patients older than 55 years were enrolled in this research. MAC regimen was given as the salvage treatment. Complete remission rate(CR), partial remission rate(PR), overall survival(OS), relapse-free survival(RFS) and adverse effect were analysed.</p><p><b>RESULTS</b>CR rate after the salvage therapy with MAC was 51.1%, partial remission (PR) rate was 6.1%, the overall response rate (ORR) was 57.6%, the median OS was 8 months (1.0-66.0 months), the median relapse-free survival (RFS) was 10.1 months (2.3-40.4 months). Mortality related with salvage treatment in 30 days was 9.1%. Low incidence of severe organ damage were found.</p><p><b>CONCLUSION</b>MAC can be used as a relative effective and safe regimen for the salvage treatment of the older AML patients.</p>
