Clinical values of CA125， CA199， CEA of plasma in pulmonary cancers and malignant tumor of digestive system
Abstract：Objective To observe diagnosis value of CA125、CA199、CEA、AFP in plasma of pulmonary cancers and malignant tumors of digestive tract. Method CA125、CA199、CEA、AFP of plasma were assessed by radio immunossay. It is positive as CA125>35 U/ml， CA199>30 U/ml，CEA>15 ng/ml，AFP>25 ng/ml. Result Compared with contrast group, it had a signifi cant difference (P<0.05) to measure the result of CA125 of plasma in pulmonary cancers, hepatoma colorectum cancer positive diagnosis of CA199 of plasma of pulmonary cancor, colorectum cancer also had a significant difference (P<0.01). Compared with signal measuring sensitivity of CA199＋AFP， CA199＋CA125＋AFP increased signifi cantly in hepatoma (P<0.01). Conclusion CA125 of plasma is important in diagnosis of pulmonary cancers, hepatoma, colorectum cancer. It is nessary to unit CA125， CA199, AFP(CEA) in diagnosis of pulmonary cancers hepatoma. But specificity of CA125， CA199 of plasma decreased in diagnosis of pulmonry cancers.
