摘要
目的 探讨肝癌患者外周血ＡＦＰ ｍＲＮＡ的表达与肝癌转移的关系。方法 采用ＲＴ－Ｎｅｓｔｅｄ ＰＣＲ技术，检测了９６例患者外周血中的ＡＦＰ ｍＲＮＡ，并采用竞争ＰＣＲ技术对其４７你阳性患者ＡＦＰ ｍＲＮＡ的含量进行了检测。结果 ＡＦＰ ｍＲＮＡ阳性率分别为：对照组，肝硬化组１３．３％，肝癌未发生转移组４２．９％，局部转移组（肝内、门脉及胆管癌栓）６１．５％，远处转移组９０．９％．
Objective: To investigate the relationship between AFP mRNA concentration in peripheral blood in patients with hepatocellular carcinoma (HCC) and tumor metastasis. Methord: 96 cases were included. The AFP mRNA concentration in peripheral blood were determined using RT-Nested PCR, and compitative RT-PCR technique were used in quatitative analysis for 47 positive eases. Results: The positive ratio was: control group 0, liver cirrhosis 13. 3%, HCC without metastasis group 42. 9%, HCC with local metastasis group 61.5%, HCC with distant metastasis 90. 9%. The results showed that significant differences between non-malignant and malignant group; HCC without distant metastasis and with distant metastasis group (P < 0.01). The presence of AFP mRNA seemed to be correlated with diameter of tumor and serum AFP value. The AFP mRNA concentrations in the positive were: liver cirrhosis group (5. 5 ×10~4±4. 5 × 10~4) copies/ml, HCC without metastasis group (1. 90 ×10~6 ±1. 02 ×10~6) copies/ml, HCC with local metastasis group (2. 58 × 10~6±2.3×10~6) copies / ml, HCC with distant metastasis (2. 98×10~7±2. 08 ×10~6 ) copies / ml. Significant differences were also found between non- malignant and malignant group; HCC without distant metastasis and with distant metastasis group (P < 0. 01). Conclusions: The detection of human AFP mRNA is very important in clinical prediction of HCC metastasis.
