Key clinical point: Biomarkers can predict relapse in patients with chronic myeloid leukemia (CML) who are eligible for a controlled treatment interruption.
Major finding: Predictors of CML relapse after treatment interruptions were low levels of cytotoxic cells such as CD56+ with low expression of CD16 and CD94/NKG2 receptors and CD8± T cells expressing TCRγβ+; low expression of activating receptors on the surface of natural killer (NK) and NK T cells; impaired synthesis of proinflammatory cytokines or proteases from NK cells; and HLA-E*0103 homozygosis and KIR haplotype BX.
Study details: The data come from an observational, cross-sectional study of 93 patients with chronic phase CML and 20 age- and gender-matched controls. Among patients with CML, 45 were on treatment with tyrosine kinase inhibitors (TKIs), 27 on sustained treatment-free remission (off TKIs), 15 had a relapse, and 6 had newly diagnosed CML.
Disclosures: The study was funded by the Foundation for Biomedical Research of the Hospital Universitario Ramón y Cajal, the Spanish Ministry of Economy and Competitiveness, and the Spanish AIDS Research Network. The authors declared no conflicts of interest.
