摘要
Abstract
Aim: To assess the clinical significance of the colorectal cancer cells in peripheral blood with reverse transcription polymerase chain reaction(RT-PCR).Methods:47 patients with colorectal cancer in different Dukes stages were examined the expression of cytokeretin 20(CK20) in cancer cells in the peripheral blood chosen by RT-PCR,which was compared with that of the tissue of colorectal cancer (20 cases).Results:In the normal person,the CK20 mRNA expression in peripheral blood had not been revealed,but the positivity rate of CK20 mRNA (in peripheral blood of patients with colorectal cancer) was 40.4%(19/47),and those in patients with Dukes stage B,C,D were 25.0%(5/20),41.2%(7/17) and 87.5%(7/8),respectively (P<0.05).The positivity rate of CK20 mRNA in patients with hepatic metastasis was 87.5%(7/8),while 30.8%(12/39)in patients without hepatic metastasis (P<0.01).Conclusion:CK20 may be a tumor marker for detecting colorectal cancer cell in peripheral blood as well as tumor relapse and metastasis.关键词
