Predicts cancer mortality from serum biomarkers.
Why Use
Multiple studies suggest significantly worse outcome in patients with multiple types of cancer.
When to Use
Patients with known cancer.
Formula
Selection of appropriate levels of serum biomarkers.
Pearls / Pitfalls
The Prognostic Index (PI) has been evaluated across numerous different cancer cohorts and suggests incrementally worsening prognosis with increasing score. Depending upon patient selection, stage, cancer, and other factors the resulting survival numbers vary widely.
Management
We are unaware of validated management algorithms using the PI.
Critical Actions
The PI requires serum laboratory values and may be relevant when drawn prior to or after cancer diagnosis.
Advice
The Prognostic Index (PI) helps stratify prognosis groups and may be a worthy addition to multifactorial evaluations.
