[Biochemical markers of the tumor origin of ascites].
In order to determine the best biochemical tests to detect cancer as the cause of ascites formation, ascitic fluid level of fibronectin, cholesterol, phospholipids and triglycerides were compared for 73 patients. The median values and the cut-off concentrations of these parameters were determined on 53 ascitic fluids without malignant cytology and 20 ascitic fluids characterized by a malignant cytology. The results showed that ascitic fluid fibronectin and cholesterol levels had a higher discriminating value than phospholipids and triglycerides to separate ascites caused by neoplasms. Cholesterol and fibronectin gave the same sensitivity and negative predictive value but cholesterol showed the highest specificity and positive predictive value.
