title: [Relationship of extrahepatic metastasis of primary hepatocellular carcinoma between circulative tumor cells in the blood of hepatoma patients].
abstract: OBJECTIVE
  To study the relationship between extrahepatic metastasis of primary hepatocellular carcinoma and circulative tumor cells in the blood of hepatoma patients.
  
  
  METHODS
  The immunomagnetic bead technique was employed to enrich and separate the hepatoma cells in the peripheral blood of preoperative and postoperative hepatoma patients. The relationship between postoperative extrahepatic metastasis and hepatoma cells in peripheral blood cancer cells were analyzed. The circulative tumor cells in the peripheral blood of hepatoma patients were enriched and separated by immunomagnetic bead technique. They were identified as hepatoma cells by AFP immunohistochemistry. Among 30 cases of hepatoma patients, the positive rate of hepatoma cells in the peripheral blood of preoperation and postoperation were 53.3% and 83.3% respectively. There was difference significantly in positive cases before operation and after operation (P<0.05).
  
  
  CONCLUSIONS
  Extrahepatic metastasis of primary hepatocellular carcinoma is obviously correlated to the positive tumor cells and the concentration in the peripheral blood of preoperative patients.
