[Tumor markers and immunomodulator substances in ascites--their value as screening and diagnosis parameters].
The object of this study was to determine the known laboratory parameters, tumor markers and immunomodulatory substances in 69 ascites of various etiology, and to test their diagnostic significance. The usual parameters such as protein content, LDH ratio, albumin quotient and albumin gradient, fibronectin, cholesterol and cell count did not reliably differentiate the etiology in each particular case, although the mean values of the various groups differed significantly. Even cytological investigation was negative in 6 out of 29 malignant ascites. Neither were the immunomodulatory substances such as neopterin, beta 2-microglobulin and interleukin-2 receptors suitable for differentiation. In patients with carcinoma of the prostate the values of prostate-specific antigen were significantly increased in ascites. The best separation between benign hepatic or cardiac ascites and malignant ascites was provided by ferritin (sensitivity 97%, specificity 100%). The values in benign hepatic or cardiac ascites were lower than 150 ng/ml and those in malignant ascites higher than 170 ng/ml.
