The Clinical value of detecting CD44v6 in plasma for colon and rectum cancer / 肿瘤研究与临床

ABSTRACT

Objective To explore the clinical value of measuring solubie serum CD44 variant 6sCD44v6 in patients with colorectal cancer. Methods Serum leves of sCD44v6 and CEA in96 patients with colorectal and in 24 healthy indivduals were detected by ELISA andchem-iluninesenle immunoassoly,respectively.Some ehnieal pathological indexes were analyzed.Results Mean sCD44v6 level in patients with colorectal cancer was 275.3+-115.8 ng/ml,which was significantly hirher than that in healthy controls(61.3+-7.8 ng/ml,P＜0.05).When using the mean+2s sCD44v6 level of healthy controls as the cut-off value,sCD44v6 level were abnormally elevated in 71 of 96(73.96%)patients with coloreeatal cancer.Conclusion The sCD44v6 leveland positive rate also increased with Dukesstage and tumor metastasis Compared with serum CEA level,the sCD44v6 level might reflect the tumor invasion and metastasis more directly and sensitively.
