Clinical Significance of Preoperative Serum CEA, CA125, and CA19-9 Levels in Predicting the Resectability of Cholangiocarcinoma

Table 2

Multivariate logistic regression models for predicting the resectability of cholangiocarcinoma.

Observation	Predicted value
	Radical resection	Nonradical resection	Correct percentage
Radical resection	43	7	86.0%
Nonradical resection	25	37	59.7%
Overall percentage	60.7%	39.3%	71.4%

The accuracy of the model in predicting surgical resectability is higher, reaching 86.0% ().
