Nomogram of Zhou et al for Predicting Survival for a Patient with an Oral Squamous Cell Carcinoma

Description

Zhou et al reported a nomogram for predicting survival for a patient with an oral squamous cell carcinoma. The authors aer from Shanghai Jiao Tong University, Kunming Medical University, and the National Clinical Research Center of Stomatology in CHina.

Patient selection: age >= 60 years with oral squamous cell carcinoma

Parameters:

(1) N stage

(2) neutrophil-to-lymphocyte ratio (NLR)

(3) hemoglobin from 60 to 180 g/L

(4) body mass index (BMI) group, units kilograms per square meter

points for hemoglobin =

= 150 - (0.8333 * (hemoglobin))

Parameter	Finding	Points
N stage	N0	0
	N1	14.7
	N2	26.4
	N3	48.9
BMI group	normal (BMI >= 18.5)	0
	low (BMI < 18.5)	14.7

NLR	Points
0 to 2	(2 * (NLR)) + 1.385
2 to 4	(8.1 * (NLR)) -10.9
4 to 6	0
6 to 24	28.8 - (1.2 * (NLR))

total score =

= SUM(points for all of the parameters)

Interpretation:

• minimum score: 0

• maximum score: 185.2

value of X =

= (-0.0002945 * ((score)^2)) - (0.004746 * (score)) + 1.831

probability of 5-year mortality =

= 1 / (1 + EXP((-1) *X))

Performance:

• The area under the ROC curve is 0.70.
