RESUMEN
Objective To evaluate the value of diagnosis of total bile acid (TBA ) ,CEA ,CA199 ,CA72‐4 in gastric carcinoma combined detection .Methods From 2013 January to 2014 April in hospital of each stage of gastric cancer in 53 patients ,80 patients in benign gastric disease group and healthy group of 120 people ,were detected the concentration of TBA ,CEA ,CA199 respectively , the serum CA72‐4 .Results Three testing groups ,detecting indexes in patients with gastric cancer group were TBA (59 .55 ± 20 . 56)μmmol/L ,CEA (17 .26 ± 11 .69)g/L ,CA199 (82 .08 ± 6 .9)U/mL ,CA72‐4 (68 .65 ± 23 .05)U/mL ,concentrations were higher than the other two groups ,with statistically significant difference between groups (P0 .05) .Conclusion TBA ,CEA ,CA199 ,CA72‐4 index can be used as the detection index of clinical judgment of gastric tumor ,with a high clinical value of combined detection indexes of gastric cancer clinical treatment and prognosis .
