ABSTRACT
<p><b>OBJECTIVE</b>To investigate the impact of polymorphisms of DNA homologous recombination (HR) repair genes RAD51-G135C and XRCC3-C241T on the prognosis of acute myeloid leukemia (AML) with inv(16)/t(16;16)(CBFbeta-MYH1).</p><p><b>METHODS</b>One hundred and three de novo inv(16)/t(16;16) (CBFbeta-MYH11) AML patients were followed-up and retrospectively analyzed. Polymorphisms of RAD51-G135C and XRCC3-C241T were detected by PCR-RFLP. The prognostic factors,including sex, age, white blood cell count, platelet count, hemoglobin level, karyotype, KIT mutation, RAD51-G135C and XRCC3-C241T polymorphisms at diagnosis, for complete remission (CR) achievement, overall survival (OS) and relapse-free survival (RFS) were analyzed by univariate and multivariate analyses.</p><p><b>RESULTS</b>The median follow-up of all patients was 28 (1 - 106) months. The overall CR rate was 92.2%. The estimated 5-year OS and RFS rates were 43.6% (95% CI 37.7% - 49.5%) and 26.4% (95% CI 21.1% - 31.7%), and the median OS and RFS were 53 (95% CI 133.4 - 72.7) and 27 (95% CI 22.9 - 31.1) months, respectively. In multivariate analysis, higher WBC (P = 0.004) and older than 30 years of age (P = 0.035) were independent poor factors for CR achievement, the XRCC3-241T variant (P = 0.007) and higher WBC (P = 0.009) were independent poor factors for 5-year RFS, and higher WBC (P = 0.002) and trisomy 8 (P = 0.035) were independent poor factors for 5-year survival. Polymorphism of RAD51-G135C had no significant impact on the prognosis.</p><p><b>CONCLUSION</b>The XRCC3-241T variant is an independent poor prognostic factor for AML with inv(16)/t(16;16)/CBFbeta-MYH11.</p>
