APACHE II Score
Expert Tip
APACHE II scores range from 0 to 71. Scores > 25 represent severe illness with high probability of clinical mortality.
Calculation Methodology & Details
Formula
Point weights are assigned based on deviation from normal physiological baseline values.

ℹ️ About this Calculation
This clinical oncology calculator provides chemotherapy dosing precision, tumor staging risk stratification, performance status scoring, and prognostic index evaluation based on ASCO and NCCN clinical guidelines.
Variable Glossary
Oncology & Lab Data
Serum creatinine/eGFR, target AUC, GFR (Calvert formula), BSA (m²), tumor size/grade, or biopsy scores.
Prognostic Index
Calculated dose (mg), ECOG grade (0-5), Nottingham Index score, or 10-year cancer risk percentage.
How to Calculate Step-by-Step
Step 1
Enter patient body surface area, GFR/creatinine clearance, or histopathological biopsy findings.
Step 2
Specify target AUC dose parameters or patient functional performance status options.
Step 3
Review calculated chemotherapy total mg dose, risk stratification category, or survival probability estimates.
