Background:
The minimal residual disease (MRD) level in patients with B-precursor acute lymphoblastic leukemia (B-ALL) is the strongest independent predictor of relapse and survival. Assessment of MRD plays a crucial role in the treatment of B-ALL.
Case Report:
We performed long-term monitoring of a 30-year-old woman with B-ALL of standard risk for MRD using multiparametric flow cytometry (MFC). After five years of monitoring, molecular relapse of the disease was confirmed.
Conclusion:
This case illustrates that more extended monitoring for MRD, even by only MFC when other newer sophisticated diagnostics are not available, is essential in detecting early relapse in patients with B-ALL of standard risk. HIPPOKRATIA 2022, 26 (1):38-40.
