description	AI-powered myeloproliferative neoplasm monitoring for disease progression prediction, treatment response tracking, and transformation risk assessment in PV, ET, and myelofibrosis.

MPN Progression Monitor Agent

The MPN Progression Monitor Agent provides comprehensive monitoring of myeloproliferative neoplasms (PV, ET, MF) for disease progression, treatment response, and transformation risk. It integrates molecular profiling, clinical parameters, and AI-based risk models to guide management of chronic phase disease and predict blast transformation.

When to Use This Skill

• When monitoring JAK2/CALR/MPL mutation burden over time.
• For predicting fibrosis progression in PV/ET.
• To assess risk of blast transformation.
• When tracking treatment response to JAK inhibitors.
• For calculating dynamic risk scores (DIPSS, MIPSS70).

Core Capabilities

1. Mutation Monitoring: Track driver and high-risk mutation VAF.

2. Progression Prediction: Model fibrosis and transformation risk.

3. Risk Scoring: Calculate DIPSS, MIPSS70+, MTSS dynamically.

4. Treatment Response: Assess molecular and clinical response.

5. Clone Evolution: Track clonal dynamics and new mutations.

6. Transplant Timing: Optimize allo-HSCT timing decisions.

MPN Classification

MPN Type	Driver Mutations	Progression Risk
PV	JAK2 V617F (95%), JAK2 exon 12	Fibrosis 10-15%, AML 2-5%
ET	JAK2 (55%), CALR (25%), MPL (5%)	Fibrosis 5-10%, AML 1-2%
Pre-PMF	Same as PMF	Variable
PMF	JAK2 (60%), CALR (25%), MPL (5%)	AML 10-20%

High-Risk Mutations

Mutation	Impact	MF Association
ASXL1	Adverse	Strong
SRSF2	Adverse	Strong (PMF)
EZH2	Adverse	Moderate
IDH1/2	Adverse	Transformation
RUNX1	Very Adverse	Transformation
TP53	Very Adverse	Transformation
U2AF1	Adverse	Moderate

Risk Scores

Score	Components	Application
IPSS	Age, Hb, WBC, blasts, symptoms	PMF at diagnosis
DIPSS	Same, dynamic	PMF follow-up
DIPSS+	+ karyotype, transfusion, platelets	PMF refined
MIPSS70	Molecular markers	Transplant-age PMF
MIPSS70+ v2.0	+ U2AF1, karyotype	Most comprehensive
MTSS	Transplant-specific	Allo-HSCT outcomes

Workflow

1. Input: Serial molecular testing, CBC, clinical parameters.

2. Baseline Assessment: Calculate initial risk score.

3. Mutation Tracking: Monitor VAF trends over time.

4. Risk Recalculation: Update scores at each timepoint.

5. Progression Detection: Identify molecular/clinical progression.

6. Treatment Assessment: Evaluate response to therapy.

7. Output: Dynamic risk assessment, progression alerts, recommendations.

2. Cytogenetic Evolution: High-risk signal, BMB follow-up
3. New Mutations: May indicate disease evolution
4. Treatment Resistance: Consider second-line or transplant
5. Quality of Life: Balance treatment intensity
