From: Simple deep sequencing-based post-remission MRD surveillance predicts clinical relapse in B-ALL
Chronology of specimen collections in the surveilled and non-surveilled relapsed B-ALL cases. Each horizontal line represents one patient with B-ALL relapse. The mean time interval between the most recent follow-up sample and overt relapse (marked) in the non-surveilled cases is significantly longer compared to that between conversion to positive MRD (CPMRD) and overt relapse (marked) in surveilled cases (20 months vs 4.7 months, p < 0.0001).
