    Abstract:

    Objective:To explore the significance loss of Kai-1 gene plays in the progression and metastasis of colorectal cancer (CRC). Methods:The deletion of Kai-1 gene were detected by using RT-PCR and validated by sequencing in the tumor of 40 cases of CRC and 15 normal cases near the tissues of CRC. Results:The deletion of exon 9 in the Kai-1 gene was found in 18 of 40 colorectal cases(45%) and in 2 of 15 normal cases near the colorectal tissues(13.3%). The frequency of the exon 9 deletion was significantly higher in the colorectal tumors than in the normal cases(P < 0.05). The frequency of the exon 9 deletion was significantly higher in the colorectal tumors with lymphatic metastasis than that without lymphatic metastasis(P < 0.05), and in the advanced stage(Dukes C,D) than in the earlier stage(Dukes A,B) of the colorectal cancer(P < 0.05). However, there was no significant difference of the frequency of exon 9 deletion when stratefied by the the age, sex, histological type as well as differentiated degree of the patients with CRC(P > 0.05). Conclusion:The deletion of the Kai-1 was associated with the progression and metastasis of CRC, and the detection of the deletion of the Kai-1 can be considered as an objective clinical marker to assess the progression and metastasis of CRC.
