肿瘤相关抗原指标在慢性乙型肝炎中的临床意义

目的 探讨肿瘤相关抗原指标在慢性乙型肝炎中的临床意义.方法 选取感染科住院治疗的乙型病毒性肝炎患者80例,按有无黄疸分为两组（无黄疸组与黄疸组）,所有患者分别检测入院时及出院前清晨空腹血清中肿瘤相关抗原指标：甲胎蛋白（AFP）、癌胚抗原（CEA）、糖链抗原199（CA199）、糖链抗原125（CA125）.结果 入院时无黄疸组与黄疸组间CEA比较差异无统计学意义（P＞0.05）;AFP、CA199、CA125比较差异有统计学意义（P＜0.01）.出院前无黄疸组与黄疸组间CEA比较差异无统计学意义（P＞0.05）;AFP、CA199、CA125比较差异有统计学意义（P＜0.01）.黄疸组入院时与出院前CEA比较,差异无统计学意义（P＞0.05）,AFP、CA199、CA125比较差异有统计学意义（P＜0.01）.无黄疸组入院时与出院前AFP比较差异有统计学意义（P＜0.05）,CEA、CA199、CA125比较差异均无统计学意义（P＞0.05）.结论 CEA在慢性乙肝患者中一般无明显异常.慢性乙肝患者如出现AFP、CA199、CA125异常增高,应积极作影像学检查或内镜检查排除肿瘤,通常这些异常指标随肝炎病情好转而明显降低.CA199、CA125异常增高常见于伴有黄疸的慢性乙肝患者.

Clinical significance of tumor-associated antigen indexes in patients with chronic hepatitis B

Objective To study the clinical significance of tumor-associated antigen indexes in patients with chronic hep- atitis B.Methods 80 patients, who were infected with hepatitis B virus and hospitalized in Department of Infection of our hospital,were selected and all the patients were divided into observation group（ with jaundice） and control group （without jaundice） .Tumor-associated antigen indexes in the serum of all the patients were detected on admission and in the morning of before hospital discharge respectively when they were on empty stomach. The indexes included alpha fetoprotein （ AFP ）, eareino-embryonieantigen（ CEA ） , carbohydrate antigen199 （ CA199 ） and carbohydrate antigen125 （ CA125 ）. Results Difference of CEA value on admission between the two groups was not statistically significant （P〉0.05） , but differences of AFP, CA199 and CA125 values between two groups were statistically significant（ P〈0.01 ）.There was also no statistic signifi- cance in CEA value difference between two groups before hospital discharge（ P〉O. 05） ,but differences of AFP, CA199 and CA125 values between these two groups were statistically significant（P〈0. 01 ）. In the observation group, difference of CEA levels on admission and before hospital discharge was not statistically significant （P〉 0. 05 ）, but there were great statistical difference of AFP, CA199 and CA125 values between the above two points of time （P〈O. 01 ）.In the control group, AFP value difference had statistical significance on admission and before hospital discharge（ P〈0. 05） , but no significant difference was found in CEA, CA199 and CA125 values between the two time points （P〉 0. 05 ）. Conclusion In general, CEA in patients with chronic hepatitis B shows no obvious abnormality.If AFP ,CA199 and CA125 are found abnormally high, imaging exami- nation or endoscopic examination should be conducted to detect the tumor.Usually these abnormal indexes obviously decrease with the improvement of h
