Models of Xu et al for a Patient with R0 Resected Head and Neck Soft Tissue Sarcoma: Nomogram Using 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 uses the Inflammatory-Nutrition Score (INS). The authors are from Sun Yat-sen University Cancer Center in Guangzhou, China.

Patient selection: R0 head and neck soft tissue sarcoma

Parameters:

(1) depth of the tumor

(2) INS group

(3) T stage

(4) N stage

(5) FNCLCC grade

Parameter	Finding	Points
depth of the tumor	superficial	0
	deep	88
INS group	low risk	0
	medium risk	14
	high risk	25.2
T stage	T1 or T2	22.4
	T3 or T4	0
N stage	N0	0
	N1	65.4
FNCLCC grade	G1	0
	G2	100
	G3	96.3

total score =

- SUM(points for all of the parameters)

Interpretation:

• minimum score: 0

• maximum score: 301

Total Score	Value of X
0 to 207.8	5.282 - (0.02504 * (score))
207.8 to 301	(-0.00041 * ((score)^2)) + (0.148 * (score)) - 13.07

probability of 7 year survival =

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

Performance:

• The area under the ROC curve is 0.82.
