Notas
Triggers re-route from ET 1L algorithm to PMF algorithm (post-ET MF) or AML algorithm (post-ET AML / MDS). Annual incidence is low; risk rises with disease duration + JAK2-mutation status + exposure to cytoreduction (especially anagrelide vs HU per PT-1). STUB — requires clinical co-lead signoff.
