To study the expressions of CA19-9 and CA125 and their clinicopathologic significances
in gallbladder adenocarcinoma , pericancerous tissues and chronic cholecystitis. Methods EnVisionTM immunohistochemist ry was used for assaying the expressive levels of CA1929 and CA125 in the routinely paraffin2embedded sections of specimens f rom gallbladder adenocarcinoma ( n = 108) , pericancerous tissues ( n = 46) , and chronic cholecystitis ( n = 35) . Results The positive rates of CA19-9 and CA125 were significantly higher in gallbladder adenocarcinoma ( 49. 1 % , 51. 9 %) than those in pericancerous tissues ( 26. 1 % , 15. 2 %) and chronic cholecystitis
(14. 3 % , 5. 7 %) , respectively ( P lt; 0. 01) . The positive rates of CA19-9 and CA125 were significantly lower in the
cases of adenomatous canceration , maximal diameter lt; 2 cm , no-metastasis of lymph node and no-invasion of regional tissues than those in the ones of low-differentiated adenocarcinoma , maximal diameter ≥2 cm , metastasis of
lymph node and invasion of regional tissues ( P lt; 0. 05 , P lt; 0. 01 ) . The consistence of CA19-9 and CA125 expressive
levels was found in gallbladder adenocarcinoma (χ2 = 44. 69 , P lt; 0. 01) . Conclusion The expressions of CA19-9 and
CA125 may be important tumor markers to reflect the carcinogenesis , progression , biological behaviors and prognosis of gallbladder adenocarcinoma.
