Abstract
AIM
To investigate the expression of cysteine rich 61 (Cyr61) and nuclear factor-κB (NF-κB) p65 in colorectal adenocarcinoma, and to explore their relationship with clinicopathologic parameters and prognosis.
METHODS
Ninety-two cases of colorectal adenocarcinoma treated at Hubei Huanggang Central Hospital from May 2010 to December 2012 were collected. Immunohistochemistry and Western blot were used to detect the expression of Cyr61 and NF-κB p65 in colorectal cancer and tumor adjacent tissues. The correlation between the expression of Cyr61 and NF-κB p65 and clinicopathological features and prognosis of colorectal adenocarcinoma was analyzed.
RESULTS
Both immunohistochemical staining and Western blot showed that the expression of Cyr61 and NF-κB p65 proteins in colorectal cancer tissues was significantly higher than that in tumor adjacent tissues (t = 24.866, P <0.001; t = 45.508, P <0.001). The expression of Cyr61 and NF-κB p65 in colorectal cancer tissue was significantly correlated (χ2 = 14.087, P < 0.001). The expression of Cyr61 in colorectal cancer tissues was significantly correlated with tumor diameter, depth of invasion, vascular invasion, and TNM stage (P < 0.05). The expression of NF-κB p65 in colorectal cancer tissues was significantly correlated with tumor diameter, lymph node metastasis, and TNM stage (P < 0.05). The 5-year overall survival rates of patients with high expression of Cyr61 or NF-κB p65 were 41.30% and 45.65%, respectively, which were significantly lower than those of patients with low expression of Cyr61 or NF-κB p65 (76.09% and 71.74%, respectively; HR = 0.341, 95%CI: 0.179-0.649, P = 0.001; HR = 0.465, 95%CI: 0.245-0.881, P = 0.019).
CONCLUSION
Cyr61 and NF-κB p65 proteins are highly expressed in colorectal cancer tissues, and high expression of Cyr61 and NF-κB p65 proteins is significantly associated with clinicopathologic parameters and prognosis in patients with colorectal cancer.
