Nomogram of Ma et al for Survival After Surgical Resection of a Gallbladder Cancer

Description

Ma et al reported a nomogram for predicting survival for a patient who has undergone surgical resection of a gallbladder cancer. This can help to identify a patient who may benefit from more aggressive or a novel therapy. The authors are from multiple institutions in China.

Patient selection: status post resection of a gallbladder cancer

Parameters:

(1) liver invasion

(2) size in cm

(3) perineural invasion

(4) surgical margin (R0 vs R1)

(5) liver resection

Parameter	Finding	Points
liver invasion	no	0
	yes	71.8
size in cm	< 4.5 cm	0
	>= 4.5 cm	58.7
perineural invasion	no	0
	yes	100
surgical margin	R0	0
	R1	94
liver resection	yes	0
	no	44.7

total score =

= SUM(points for all of the parameters)

Interpetation:

• minimm score: 0

• maximum score: 369.2

value of X =

= (-0.00007891 * ((score)^2)) - (0.01221 * (score)) + 1.187

probability of 5-year survival =

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