ABSTRACT
Objective To explore the clinical value of B ultrasound-guided psychro-circulation percutaneous microwave coagulation therapy(PMCT) in the treatment of liver cancer.Methods One hundred and sixteen liver cancer patients with 154 lesions were selected to receive psychro-circulation PMCT in our department from July 2004 to December 2007.The pre-and postoperative alpha fetoprotein(AFP) levels were detected.The diameters and blood flow state of the tumors were measured and compared by use of B ultrasound and computerized tomographic scanning(CT).The postoperative 1,2 and 3 y survival rate of those patients was followed up and recorded.Results No mortality or severe complications occurred in this series.Preoperative serum AFP level of the patients was(421.6?36.5)?g/L and decreased obviously to(232.5?25.6)?g/L at 1 month after psychro-circulation PMCT(P
