[Evaluation of detecting 9 tumor markers in serum for diagnosis of primary liver cancer].
Nine tumor markers in serum including alpha-fetoprotein (AFP), r-glutamyltranspeptidase (GGT), lactate dehydrogenase (LDH), alpha 1-antitrypsin (alpha 1-AT), total sialic acid (TSA), ferritin (Ft), ceruloplasmin (CP), LDH isoenzymes and GGT isoenzymes were used for differential diagnosis of primary liver cancer. Of 5 measurement data tested by statistics, CP and TSA were close to normal distribution (P > 0.1), GGT, LDH and alpha 1-AT showed skewness distribution or to be close to normal distribution with in transformation (P > 0.1). The results indicated that the determination of the cut-off value should depend on the statistical distribution of data. Analysis of single and dual-combination tests as well as triple analysis with sequential progressive screening had been performed to evaluate the predictive value of clinical diagnosis, i.e. the sensitivity, the specificity and the correct diagnosis efficiency. Three predictive values of a single test were lower than what clinical diagnosis raqvest. The dual-combination tests had higher specificity but a lower sensitivity. For triple analysis with sequential progressive screening among the liver cancer group (n = 23), the related disease group (n = 44) and the healthy individuals group (n = 40), the correct diagnosis efficiency was 95%, 97.3% and 100%, respectively. This suggests that the method described here has potential value in clinical practice.
