Objective To probe into the significance of tuftsin in patients with liver cancer. MethodsThe serum tuftsin level of 12 patients with liver cancer before and after the resection，20 cirrhostic and 20 normal controls were measured by radioimmunoassay (RIA). ResultsTuftsin level in preoperative group （449±106） ng/ml was much lower than that in postoperative group (588±129) ng/ml，cirrhotics group (580±187) ng/ml and control group (703±128) ng/ml (P＜0.01). The tuftsin level in postoperative group was also quite lower than that in control group (P＜0.01). Conclusion We should try our best to excise the liver cancer so that a higher tuftsin level might be obtained which can activate NK cell and T cell.
