Model of Sasaki et al for Predicting 5-Year Survival Following Resection of Hepatic Metastases from a Colorectal Adenocarcinoma

Description

Sasaki et al developed a model for predicting survival after resection of liver metastases from a colorectal adenocarcinoma. This can help to identify a patient who may benefit from more aggressive management. The authors are from Oita University in Japan.

Patient selection: colorectal adenocarcinoma with liver metastases

Outcome: 5-year survival after surgery

Preoperative parameters:

(1) interval between colorectal and hepatic surgery in months

(2) number of liver metastases

(3) preoperative CEA concentration in ng/mL (method not given; ULN reference range apparently < 10 ng/mL)

Parameter	Finding	Points
interval between surgeries	< 12 months	1
	>= 12 months	0
number of liver metastases	1 to 3	0
	>= 4	1
serum CEA concentration	< 10 ng/mL	0
	>= 10 ng/mL (elevated)	1

total score =

= SUM(points for all 3 parameters)

Interpretation:

• minimum score: 0

• maximum score: 3

• The higher the score the worse the prognosis.

• 5-year survival without resection was 0% (same as for score of 3).

Total Score	5-Year Survival
0	75%
1	54%
2	23%
3	0%
