Liang et al developed a nomogram for predicting survival in a patient with a resected non-small-cell lung cancer (NSCLC). This can help to identify a patient who may benefit from more aggressive management. The authors are from multiple hospitals and universities in China.
Patient selection: resected NSLC
Parameters:
(1) age in years
(2) histologic type of NSCLC
(3) number of sampled lymph nodes
(4) gender
(5) T stage
(6) N stage

total score =
= SUM(points for all 6 parameters)
Interpretation:
• minimum score: 0
• maximum score: 32.5
• The higher the score the lower the 5 year survival rate.
