🩸 WPSS (MDS WHO Classification-Based)

UseWhen to use: MDS counseling when WHO morphology, cytogenetics, and transfusion dependence are known.

Strata0 very low → 5–6 very high; higher scores associate with poorer survival / AML evolution risk.

LimitsWhen not to use: after AML transformation pathways. · Pitfall: outdated WHO label mapping. · Not a sole transplant order.

Clinical takeaway

WHO + karyotype + transfusion.

When to use

When to use: MDS counseling when WHO morphology, cytogenetics, and transfusion dependence are known.

How it works

WHO 0–3 + karyotype 0–2 + regular transfusion 0–1 (max 6).

Key points

  • WHO + karyotype + transfusion.
  • Dynamic over time.
  • Next: IPSS-R / IPSS-M.

Worked calculation

The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
