Notas

TP53-mutated MDS is its own WHO 5th-edition entity with median OS ~6-9 months on standard HMA. AlloHCT carries higher relapse risk vs TP53-wt. Active research questions: ven+aza vs aza alone, magrolimab + aza (failed phase-3 ENHANCE), eprenetapopt + aza (mixed results). NOT clear best regimen — flagged as intensify but the algorithm should also surface palliative-intent option. STUB — requires clinical co-lead signoff.
