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)

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).

Value

A list containing:

GPS_Score	The calculated score (0, 1, or 2).
Prognosis	Risk classification (Good, Intermediate, Poor).

Examples

# Example 1: Poor Prognosis
# CRP 20 (>10), Albumin 30 (<35)
# Score = 2
gps_cancer_score(20, 30)

# Example 2: Good Prognosis
# CRP 5 (<10), Albumin 40 (>35)
# Score = 0
gps_cancer_score(5, 40)
