Study on combined assay for serum tumor markers in patients,with hepatic carcinoma

摘要

INTRODUCTIONSince the hepatic solid-occupying lesion (HSOL) wasfound by both ultrasonoscopy (US) and computed tomography(CT).If the customary alpha-fetoprotin (AFP) standard fordiagnosis primary hepatic carcinoma is used,those cancerswith lower AFP concentration may miss the diagnosis.Onthe other hand,the use of the standard:AFP-positive(≥20μg/L)+HSOL=primary hepatocellular carcinoma(PHCC),may yield false positive results.In order to ele-vate both the preoperative and differential diagnosis levels forhepatic carcinoma,we assayed combindedly the preoperativelevels of serum AFP,carbohydrate antibody (CA) 19-9 andcarcinoembryonic antigen (CEA) in the patients with HSOL.
