Datta et al developed a simple score for predicting risk of adjuvant therapy being omitted in a patient following resection of a gastric cancer. The authors are from the University of Pennsylvania in Philadelphia.
Patient selection: gastric cancer following surgical resection
Parameters:
(1) age in years
(2) comorbidity
(3) health insurance
(4) tumor location
(5) clinical T stage
(6) clinical N stage

score =
= SUM(points for all 6 parameters)
Interpretation:
• minimum score: 0
• maximum score: 12
• The higher the score the greater the risk of adjuvant therapy omission.
