The detection of CEA mRNA in gallbladder bile of patients with colorectal cancer and its clinical significance / 中国普通外科杂志

ABSTRACT

Objective To evaluate the clinical significance of CEA mRNA expression in gallbladder bile for early diagnosis of liver metastasis from primary colorectal cancer. Methods [WT5”BZ] A CEA specific nest RT PCR assay was used to detect CEA mRNA expression in the gallbladder bile of 46 patients with colorectal cancer. Results The positive rate of CEA mRNA in gallbladder bile was 74%. The rate was directly proportional to that of live metastasis. Liver metastasis developed in 33% of patients with positive CEA mRNA expression. Conclusions The positive expression of CEA mRNA in gallbladder bile is a proof of prospective liver metastasis.
