| Outline of Final Research Achievements |
To improve “stratification strategy based on prognostic factors”, we planned to establish detection system of micro residual disease (miRD) with higher sensitivity compared to standard methods. First, we assessed sensitivity using virtual tumor specimen with serial dilution by next generation sequencer, and 10-3 to 10-4 of miRD could be detected. Using this method, by obtaining miRD status, we could illustrate dynamic evolutionary process of a case with unique coincidence of ALL and LCH. Furthermore, we performed miRD detection using droplet digital PCR technology, and its sensitivity and quantitativity.
