Description

Transarterial chemoembolization (TACE) can be used to treat some patients with hepatocellular carcinoma. Wang et al reported the "six and twelve" score (based on the cutoffs below) for evaluating these patients. The authors are from multiple institutions in China.


The score shares features with the "up-to-seven" score of Mazzaferro et al.

 

Patient selection: hepatocellular carcinoma

 

Parameters:

(1) largest tumor diameter in cm

(2) number of tumors

 

score =

= (largest tumor diameter) + (number of tumors)

 

Interpretation:

• minimum score: 2

• maximum score: 30

 

Score

Median Survival

<= 6

49.1 months

6.01 to 12

32 months

> 12

15.8 months

 

value of X =

= (-0.003593 * ((score)^2)) - (0.06355 * (score)) + 1.328

 

2-year probability of survival =

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