With the recent advent of molecular techniques, such as droplet digital polymerase chain reaction (ddPCR), tumor-derived fragmented DNA in the plasma or serum, known as circulating tumor DNA (ctDNA), represents one of the most sensitive, non-invasive biomarkers available for use in cancer patients. Successful applications of such so-called liquid biopsy techniques reported to-date include the monitoring of tumor burden and minimal residual disease (MRD), evaluation of tumor clonal heterogeneity; prediction of response to treatment with molecularly targeted drugs; and detection of metastasis in many solid tumor types and hematological malignancies. Several recent studies have indicated that ctDNA quantification can be used as an alternative to conventional MRD detection modalities for hematological malignancies. Of these, Nakamura and Yokoyama et al. performed a retrospective study in 31 patients with AML and MDS undergoing allogeneic hematopoietic stem cell transplant (alloSCT) in their research hospital. They investigated the impact of residual ctDNA status on cumulative incidence of relapse (CIR) and overall survival (OS) rate. The result was as follows: 1) Diagnostic ctDNA and matched tumor had excellent correlations with regard to variant allele frequencies. 2) Residual ctDNA persistence either at 1month or 3 months post alloSCT was associated with higher 3-year cumulative incidence of relapse and inferior OS rates.
