Detection of Early Cervical Cancer Patient’s Peripheral Blood CK19 mRNA before Surgery and its Clinical Significance / 昆明医科大学学报

ABSTRACT

Objective To investigate the detection of early cervical cancer patient's peripheral blood CK19 mRNA and its clinical significance. Methods 30 early (ⅠA2~ⅡA) cervical cancer patients from the department of gynecological tumors in the third affiliated hospital of Kunming Medical University were selected as experimental group, 15 patients with uterine myoma and 15 healthy volunteers as negative control group,15 advanced (ⅡB~ⅢB) cervical cancer patients as positive control group. Peripheral blood samples before receiving radical resection of experimental group,and the same samples before treatment of control groups were collected. The change of relative expression level and positive rate of peripheral blood CK19 was analyzed using qRT-PCR technique, and its correlation with clinicopathological parameters and prognosis was further analyzed. Results There was significant difference in relative expression level of CK19 mRNA in the peripheral blood between experimental group and control groups ( 0.05) . Conclusions CK-19 mRNA is a specific and suitable molecular marker for the detection of circulating tumor cells in early cervical cancer. Detection of peripheral blood CK19 mRNA expression before receiving radical hysterectomy in patients with early cervical cancer can also make up for the disadvantage of other methods such as the imaging, tumor marker detection. Most important of all, it can provide the basis for choosing a proper adjuvant therapy post-operation and estimating the relapse and prognosis.
