Objective To evaluate serum AFP levels and their influence factors in patients with hepatocellular carcinoma.Methods From January 1995 to December 1999,140 patients were subjected to hepatectomy in our hospital,AFP levels of the patients were evaluated.The data of the patients were analyzed by nonconditional logistic regression with SPSS10.0.Results The positive rate of AFP was 62.9% in patients with hepatocellular carcinoma.The positive rate of AFP of small hepatocellular carcinoma(52.0%) was significantly higher than that of large hepatocellular carcinoma (73.9%) ( P <0.05).It was showed that the AFP levels were related to tumor size and cirrhosis through logistic regression( P <0.05).Conclusion Sensitivity of AFP in hepatocellular carcinoma diagnosis,especially in small hepatocellular cancer was lower.It was notably increased when combined with other diagnostic methods. |
