gps_cancer_score: Glasgow Prognostic Score (GPS) for Cancer Outcomes
Description
Calculates the Glasgow Prognostic Score (GPS) to predict survival outcomes in patients with advanced cancer. This score uses C-Reactive Protein (CRP) and Albumin levels to reflect the systemic inflammatory response and nutritional status, which are strong independent prognostic factors in various malignancies.
Usage
gps_cancer_score(crp_mg_l, albumin_g_l)
Value
A list containing:
GPS_Score
The calculated score (0, 1, or 2).
Prognosis
Risk classification (Good, Intermediate, Poor).
Arguments
crp_mg_l
Numeric. Serum C-Reactive Protein level in mg/L. (> 10 mg/L indicates elevated inflammation).
albumin_g_l
Numeric. Serum Albumin level in g/L. (< 35 g/L indicates hypoalbuminemia).
