HC-ONC-007: Leukemia Synthetic Dataset β€” Simulation Engine
XpertSystems.ai | SKU: HC-ONC-007 | Version 1.0.0 | April 2026
HIPAA-Safe Synthetic Data β€” No Real Patient Records
Generates biologically consistent leukemia patient cohort covering:
- AML, ALL, CML, CLL, APL subtypes with WHO 2022 classification
- ELN 2022 cytogenetic/molecular risk stratification
- Treatment protocols: 7+3, HyperCVAD, Venetoclax+AZA, ATRA+ATO, TKI
- MRD response trajectory modeling
- Bone marrow transplant (HSCT) outcomes calibrated to CIBMTR benchmarks
Usage:
python hc_onc_007_simulation_engine.py --n_patients 25000 --seed 42 --output_dir ./output
