Standard plan

★ DEFAULT

Indication

IND-PV-1L-PHLEBOTOMY-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
Aspirin (DRUG-ASPIRIN) 81-100 mg PO daily (low-dose aspirin) · continuous · PO ⚠ Out-of-pocket

Reason

Primary current-line option selected by ALGO-PV-1L at step 3.

Other current-line alternatives (1 tracks)

Same treatment line; review when biomarker, access, contraindication, or patient-context assumptions change.

Red flags — PRO / CONTRA aggressive

PRO-AGGRESSIVE

Triggers that push toward the aggressive track

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 + ASARF-PV-ET-HIGH-THROMBOSIS-RISK
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)RF-PV-ET-ORGAN-DYSFUNCTION
PV or ET patient pregnant or planning pregnancy — HU and anagrelide contraindicated; switch to interferon-α (PEG-IFN-α2a or ropeginterferon)RF-PV-ET-PREGNANCY-OR-PLANNING
PV resistant or intolerant to hydroxyurea per ELN criteria: persistent need for phlebotomy on HU 2 g/day, persistent symptoms, splenomegaly progression, cytopenias at minimum effective HU dose, or HU-related cutaneous ulcers — switch to ruxolitinib (RESPONSE)RF-PV-HU-RESISTANCE-INTOLERANCE

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-PV-1L-PHLEBOTOMY-ASA)

Do not skip JAK2 V617F testing — diagnostic criterion + may escalate risk score.
Do not prescribe ASA in extreme thrombocytosis (plt >1500K) without ruling out acquired vWD — bleeding risk.
Do not skip abdominal vein thrombosis screening at presentation — atypical presentation in PV.
Do not prescribe iron supplementation for iron-deficiency from phlebotomy without a clear clinical cause — this is a desired effect.
Do not use full-dose ASA (325 mg) — low-dose (81-100 mg) equally effective with lower bleeding risk.

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

Do not skip ELN-criteria for HU-resistance/intolerance — quickly escalate to ruxolitinib (RESPONSE) on response.
Do not prescribe HU in patients with cutaneous ulceration history — ulcer recurrence likely.
Do not skip monthly CBC for the first 3 months — myelosuppression-titrating.
Do not prescribe HU in pregnancy / pregnancy plans — switch to IFN-α.
Do not combine with peg-IFN-α without a clear protocol — dosing of both changes.
