ABSTRACT
Objective To detect the expressions of human telomerase tranacriptase (hTERT) and MMP-7 mRNA in the peripheral blood of patients with cardia cancer.Methods Total RNA was extracted with TRIzol and was transcribed reversely into cDNA.RT-PCR was used to detect mRNA expression of MMP-7 and hTERT in the peripheral blood of 157 patients with cardia cancer.81 patients without metastasis were followed up for 12 months.Results Of 157 patients,73 cases (46.0 %) and 61 cases (38.8 %) had the positive expressions of hTERT,MMP-7,respectively.There were significant correlations between the blood micro-metastases MMP-7 and hTERT expressions and TNM staging (x2 =10.624,14.530),tumor metastasis (x2 =7.294,12.824),and differentiation degree (x2 =12.003,6.482),but no significant correlations were seen in sex (x2 =2.597,0.199) and age (x2 =4.314,0.073).There was statistically significant in the occurrence rate of tumor metastasis between 6-month and 12-month follow-up.The occurrence rate of metastasis in patients with micro-metastases was 6.12-fold compared with patients without micro-metastases after 12-month follow-up.Conclusion Detection of MMP-7 and hTERT expressions can be used as reliable markers to predict peripheral blood micro-metastasis in patients with cardia carcinoma.
