The correlation between serum levels of tumor markers and clinical pathological characteristics in gastric cancer patients

Abstract

Objective To investigate the relationship between the serum levels of CEA,cAl25,CA19-9 and clinical pathological characteristics in gastric cancel patients.Method The serum levels of CEA,CA125 and CA19-9 in 107 gastric cancer patients before the surgery were detected by electrochemiluminescence immunoassay.Results The preoperative seurm levels of CEA,CA125 and CA19-9 were not correlated with sex,age and the location of the tumor.The serum level of CEA,CA125 and CA19-9 in patients with lymph node metastasis were higher than those in patients without lymph node metastasis.The serum levels of CEA,CA125 and CA19-9 were positively correlated with the depth of tumor invasion and the size of the tumor.The serum levels of CA125 were correlated with the degrees of differentiation.Thehigher the CA125 levels,the lower the degrees of differentiation.But the levels of CEA and CA19-9 were not correlated with differentiation.There were positive.correlations among the serum levels of CEA,CA125 and CA19-9.The correlation coefficient of CA125 and CA19-9 was 0.623(P<0.01),CA125 and CEA was 0.572(P<0.01),CA19-9 and CEA was 0.412(P<0.01).Conclusions The serum levels of CEA,CA125 and CA19-9 in gastric cancer patients are significantly related with the size of the tumor,the depta of tumor invasion and lymph node metastasis.The preoperative serum levels of CEA,CA125 and CA19-9 can provide some reference for formulating the treatment of the gastric cancer patients.
