Indication

IND-ET-1L-ASA

Regimen

Hydroxyurea (PV / ET high-risk 1L cytoreduction) + baseline phlebotomy/ASA

Drugs + NSZU

Hydroxyurea (DRUG-HYDROXYUREA) Start 500-1500 mg/day PO (15-25 mg/kg/day); titrate to target · continuous PO daily; titrate by CBC q2-4wk initially, then q1-3 mo once stable · PO ✓ NSZU covered

Red flags — PRO / CONTRA aggressive

PRO-AGGRESSIVE

Triggers that push toward the aggressive track

ET transformation to post-ET myelofibrosis (~5-10% over 15 years) or to AML / MDS (rare ~1-5%): rising LDH, new splenomegaly, leukoerythroblastic smear, increasing reticulin fibrosis on trephine, blast appearance — re-stage, switch to MF or AML algorithm
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…
RF-ET-TRANSFORMATION-PROGRESSIONSRC-NCCN-MPN-2025SRC-ESMO-MPN-2015
PV or ET patient elderly or frail (age ≥80, ECOG ≥3, multiple comorbidities, life expectancy <5 years) — gentler cytoreduction (lower HU dose), expanded transfusion + monitoring strategy
Direction "investigate"-equivalent — surfaces dose-attenuation annotation; does not switch indication. Older patients tolerate HU well long-term but the leukemogenic-conversion concern weighs less; choice often defaults to HU 1L…
RF-PV-ET-FRAILTY-AGESRC-NCCN-MPN-2025SRC-ESMO-MPN-2015
PV or ET high-risk for thrombosis: age >60 OR prior arterial / venous thrombosis OR (ET only) JAK2 V617F + CV risk factors (IPSET-thrombosis high) — triggers cytoreduction (HU 1L) in addition to baseline phlebotomy + ASA
Drives selection between low-risk (phlebotomy + ASA only for PV; ASA only for ET) and high-risk (add HU 1L cytoreduction). For PV, ELN 2018 also flags WBC ≥11 as supplementary risk. For ET, IPSET- thrombosis explicitly weights JAK2 V617F…
RF-PV-ET-HIGH-THROMBOSIS-RISKSRC-NCCN-MPN-2025SRC-ESMO-MPN-2015SRC-RESPONSE-VANNUCCHI-2015
PV or ET patient with organ dysfunction limiting cytoreductive choice: severe renal impairment (CrCl <30 — limits HU), severe hepatic dysfunction (limits ruxolitinib), or severe cardiac dysfunction (limits anagrelide)
Direction "investigate" — surfaces dose-modification / agent-substitution annotations, not a binary indication switch. CrCl <30 → reduce HU dose, monitor for myelosuppression. Hepatic dysfunction → reduce/avoid ruxolitinib (CYP3A4…
RF-PV-ET-ORGAN-DYSFUNCTIONSRC-NCCN-MPN-2025SRC-ESMO-MPN-2015
PV or ET patient pregnant or planning pregnancy — HU and anagrelide contraindicated; switch to interferon-α (PEG-IFN-α2a or ropeginterferon)
Direction "investigate" — surfaces an agent-substitution annotation. Pregnancy in MPN is high-risk (placental thrombosis, IUGR, miscarriage) and requires hematology + maternal-fetal-medicine co-management. Interferon-α is the…

CONTRA-AGGRESSIVE

Hard contraindications to escalation

What NOT to do

Explicit prohibitive rules, each grounded in a regimen / supportive care / contraindication entity

Standard plan (IND-ET-1L-ASA)

Do not skip JAK2 / CALR / MPL testing — driver-mutation status determines subtype + IPSET-thrombosis risk.
Do not prescribe ASA in extreme thrombocytosis (plt >1500K) without ruling out acquired vWD — check ristocetin cofactor activity.
Do not skip prefibrotic-PMF differential on trephine — same presentation, worse prognosis.
Do not prescribe anagrelide 1L — PT-1 trial showed lower cardiovascular profile + HU more preferable.
Do not use full-dose ASA — low-dose is standard.

Aggressive plan (IND-ET-1L-HU)

Do not prescribe HU during pregnancy / pregnancy plans — switch to IFN-α.
Do not skip monthly CBC for the first 3 months — myelosuppression-titrating.
Do not use anagrelide 1L — PT-1 trial showed HU advantage on arterial thrombosis and MF progression.
Do not prescribe in cutaneous ulceration history — risk of recurrence.
Do not combine with peg-IFN without a clear protocol.
