(A) Histology (H&E) of the tonsil at disease recurrence. (B) RT-qPCR amplification plot of marker TCR Dd2.Dd3 (Marker B) at first diagnosis by backtracking analysis in BM (green curves) and at disease recurrence in the tonsil (yellow curves). Quantitative range 1 × 10−3 (red curves). (C) Timeline of the disease monitoring by RT-qPCR with marker IgH.DH3.JH6 (Marker A), by RT-PCR of p190 BCR::ABL1 transcript (P190), and by RT-qPCR with marker TCR Dd2.Dd3 (Marker B). Abbreviations: Dx, diagnosis; D, day; EOI, end-of-induction; EOC, end-of-consolidation; Pos, positive; Neg, negative; T-LBL, T-cell lymphoblastic lymphoma; BCP-ALL, B-cell precursor acute lymphoblastic leukemia.
