To evaluate the clinical advantage of the ratio of serum ornithine carbamoyltransferase (OCT) to alanine aminotransferase (ALT) in the diagnosis of hepatocellular carcinoma (HCC).
Serum levels of hepatic enzyme markers and their combinations were evaluated and compared with those of two other markers for HCC.
OCT/ALT was significantly higher in case of HCC than chronic hepatitis or liver cirrhosis. Its sensitivity (64.3%) was higher than those of alpha-fetoprotein and PIVKA-II (21.4% and 42.9%, respectively). Fluctuations of OCT/ALT before and after treatment were similar to those of alpha-fetoprotein.
OCT/ALT is a potent indicator for the diagnosis and the prognosis of HCC.
评估血清鸟氨酸氨基甲酰转移酶（OCT）与丙氨酸氨基转移酶（ALT）的比值在肝细胞癌（HCC）诊断中的临床优势。
评估并比较了肝酶标志物的血清水平及其组合与另外两种HCC标志物的血清水平。
HCC患者的OCT/ALT显著高于慢性肝炎或肝硬化患者。其敏感性（64.3%）高于甲胎蛋白和异常凝血酶原（分别为21.4%和42.9%）。治疗前后OCT/ALT的波动与甲胎蛋白相似。
OCT/ALT是HCC诊断和预后的有力指标。
