Eom et al developed a nomogram for predicting survival of gastric cancer patients after curative surgery in Korea. It has subsequently been validated in other populations. The authors are from multiple hospitals in the Republic of Korea.
Patient selection: gastric cancer patient after curative resection
Outcome: 5-year survival
Parameters:
(1) age in years
(2) lymph node dissection
(3) location in the stomach
(4) lymphovascular invasion
(5) size in cm
(6) depth of invasion
(7) number of lymph nodes with metastase

total score =
= SUM(points for all 7 parameters)
Interpretation:
• minimum score: 0
• maximum score: 395.2
• The higher the score the worse the 5-year survival.
