Response assessment. Response rates by IWG-2006 (A) and IWG-2023 (B). CRh is defined as “BM: <5% myeloblasts; and dysplasia may persist; PB: not meeting criteria for CR or CRL, no Hb threshold required, platelets ≥50 × 10⁹/L; neutrophils ≥0.5 × 10⁹/L; and blasts 0%”⁸; CRL is defined as “BM: <5% myeloblasts; and dysplasia may persist; PB: blasts 0%; CRLuni: PB, not meeting CR but only 1 of the following: Hb ≥10 g/dL; platelets ≥100 × 10⁹/L; and neutrophils ≥1.0 × 10⁹/L; CRLbi: PB, not meeting CR but only 2 of the following: Hb ≥10 g/dL; platelets ≥100 × 10⁹/L; and neutrophils ≥1.0 × 10⁹/L.”⁸ CCR, complete cytogenetic response; HI-E, HI-erythroid; HI-P, HI-platelets; PB, peripheral blood; SD, stable disease.
