Score of Wang et al for Predicting Perioperative Blood Transfusion for a Patient Undergoing Liver Resection for a Hepatocellular Carcinoma

Description

Wang et al developed a score for predicting perioperative blood transfusion in a patient undergoing hepatic resection for a hepatocellular carcinoma. This can help to identify a patient who may require more aggressive management. The authors are from Sichuan University in Chengdu, China.

Patient selection: hepatic resection for hepatocellular carcinoma

Outcome: perioperative blood transfusion

Parameters:

(1) extent of the hepatic resection

(2) extrahepatic procedure (vascular for tumor thrombi, splenectomy, adrenalectomy, etc)

(3) preoperative hemoglobin concentration in g/L

(4) preoperative platelet count in 10^9/L

Parameter	Finding	Points
extent of liver resection	minor	0
	major (more than 3 segments)	1
extrahepatic procedure	no	0
	yes	3
hemoglobin concentration	> 110 g/L	0
	<= 110 g/dL	2
platelet count	> 50 * 10^9/L	0
	<= 50 * 10^9/L	1

total score =

= SUM(points for all 4 parameters)

Interpretation:

• minimum score: 0

• maximum score: 7

• The higher the score the greater the likelihood of perioperative transfusion.

Total Score	Risk Group	Percent Transfused
0 to 2	low	11%
3 or 4	intermediate	25%
5 to 7	high	57%

Performance:

• The area under the ROC curve was 0.74 in the development group.
