Prealbumin/CRP Based Prognostic Score, a New Tool for Predicting Metastasis in Patients with Inoperable Gastric Cancer

Table 4

Receiver operating characteristic (ROC) analysis and optimum cut-off point of prealbumin for predicting metastasis in patients with inoperable gastric adenocarcinoma.

	PA	AUC	SEN	SPE	PPV	NPV	LR^+	LR^−
mets	0.20	0.68	77.1%	52.2%	71.1%	60.0%	1.61	0.44
		(0.54–0.82)	(61.0–87.9)	(33.0–70.8)	(55.2–83.0)	(38.7–78.1)	(1.01–2.56)	(0.21–0.90)

Mets: metastasis; 95% confidence interval (CI); PA: prealbumin (mg/dL); AUC: area under the curve; SEN: sensitivity; SPE: specificity; LR⁺: positive likelihood ratio; LR⁻: negative likelihood ratio; NPV: negative predictive value; PPV: positive predictive value.
