Scoring System of Nagashima et al for a Patient with Hepatic Metastases from a Colorectal Carcinoma

Description

Nagashima et al reported a scoring system for patients with hepatic metastases from a colorectal primary. This can help to identify a patient who may benefit from resection of the metastases. The authors are from Teikyo University and the University of Tokyo.

Patient selection: hepatic metastases from a colorectal carcinoma

Parameters:

(1) primary colorectal carcinoma shows serosal invasion (T4)

(2) primary colorectal carcinoma has lymph node metastases (N1 or N2)

(3) number of hepatic metastases

(4) maximum diameter of a hepatic metastasis in cm

(5) extrahepatic metastases

Parameter	Finding	Points
serosal invasion	absent	0
	present	0.8057
lymph node metastses	absent	0
	present	0.8375
number of hepatic metastases	1 (solitary)	0
	>= 2 (multiple)	0.8609
diameter	<= 5 cm	0
	> 5 cm	1.4532
extrahepatic metastases	absent	0
	present	1.3957

total score =

= SUM(points for all 5 parameters)

Interpretation:

• minimum score: 0

• maximum score: 5.353

Total Score	Grade	5-Year Survival
<=1.00	A	73%
1.01 to 3.00	B	35%
3.01 to 5.00	C	0%
> 5.00	D	0%

Patients in Grades A and B were good candidates for resection of hepatic metastases.

Patients with Grade D would be poor candidates for hepatic resections.

Grade C may be a candidate.
