Abstract:
Objective To approach the correlation between preoperative detection of serumal carcinoembryonic antigen (CEA ) and carbohydrate antigen 19‐9(CA19‐9) and primary tumor/regional lymph nodes/distant metastasis(TNM) staging ,clinicopatho‐logic staging and clinical features of patients with colorectal cancer (CRC) ,and to explore their clinical significance .Methods The dates of 231 patients with CRC treated in the First Affiliated Hospital of Chongqing Medical University from April 2011 to January 2013 were gathered .Then ,the relationship between detection of CEA and CA19‐9 and TNM staging ,clinicopathologic staging and clinical features of patients with CRC were analyzed . Results The positive rate of CEA in patients with CRC was 51 .5%(119/231) and the positive rate of CA19‐9 in patients with CRC was 46 .3% (107/231) .The positive rates of CEA and CA19‐9 were positively correlated with the TNM staging and clinicopathologic staging of CRC (P<0 .05) .Conclusion The positive rate of CEA and CA19‐9 were associated with the tumor progress and metastasis ,so the detection of CEA and CA19‐9 could be used as one of important serumal marker for clinicopathologic staging of CRC .Also ,detection of CEA and CA19‐9 could be used for prog‐nosis judgment and therapeutic schedule institution .
