Models of Xu et al for a Patient with R0 Resected Head and Neck Soft Tissue Sarcoma: Nomogram Without the Inflammatory-Nutrition Score (INS)

Description

Xu et al reported models for predicting survival in a patient with an R0 head and neck soft tissue sarcoma. These include 2 nomograms, one of which does not use the Inflammatory-Nutrition Score (INS) and which is based on the AJCC 7th edition. The authors are from Sun Yat-sen University Cancer Center in Guangzhou, China.

Patient selection: R0 head and neck soft tissue sarcoma

Parameters:

(1) T stage

(2) N stage

(3) FNCLCC grade

Parameter	Finding	Points
T stage	T1	21.5
	T2	100
	T3	0
	T4	81.1
N stage	N0	0
	N1	50
FNCLCC grade	G1	0
	G2	92.4
	G3	90.2

total score =

- SUM(points for all of the parameters)

Interpretation:

• minimum score: 0

• maximum score: 260

value of X =

= (-0.0000607 * ((score)^2)) - (0.01661 * (score)) + 4.86

probability of 7 year survival =

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

Performance:

• The area under the ROC curve is 0.78.
