Zhuang et al reported a nomogram for predicting survival for a patient with an oral squamous cell carcinoma. This can help to identify a patient who may benefit from more aggressive or a novel therapy. The authors are from Fujian Medical University and Nanjing University in China.
Patient selection: oral squamous cell carcinoma
Parameters:
(1) age in years
(2) tumor stage from I to IV
(3) albumin to globulin ratio (AGR)
(4) neutrophil to lymphocyte ratio (NLR)

total score =
= SUM(points for all of the parameters)
Interpretation:
• minimum score: 0
• maximum score: 20
value of X =
= 2.743 - (0.144 * (score))
probability of 5-year survival =
= 1 / (1 + EXP((-1) * X))
Performance:
• The area under the ROC curve is 0.66.
