Nomogram of Wang et al for Predicting Survival of a Patient with Limited Stage Upper Aerodigestive Tract Extranodal Natural/T-Cell Lymphoma Nasal Type (ENKTCL)

Description

Wang et al reported a nomogram for predicting overall survival for a patient with upper aerodigestive tract extranodal natural killer/T-cell lymphoma, nasal type. This can help to identify a patient who may benefit from more aggressive management. The authors are from Zhengzhou University in China.

Patient selection: upper aerodigestive tract Extranodal Natural/T-Cell Lymphoma Nasal Type (ENKTCL), Stage IE or IIE

Parameters:

(1) age in years

(2) stage

(3) radiation therapy

(4) primary site

Parameter	Finding	Points
age in years	<= 45 years	0
	46 to 65 years	21.7
	> 65 years	59
stage	IE	0
	IIE	75.2
radiation	no	100
	yes	0
primary site	nasal cavity, paranasal sinus	0
	other	52.3

total score =

= SUM(points for all of the parameters)

Interpretation:

• minimum score: 0

• maximum score: 286.5

value of X =

= (-0.00003541 * ((score)^2)) - (0.008342 * (score)) + 1.069

probability of 5-year survival =

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

Performance:

• The area under the ROC curve was 0.72 in the training an 0.74 in the validation cohorts.
