Abstract:
Purpose To analyze the expression of FOXA3 in colorectal cancer(CRC)and its correlation with clinicopatho-logical features.Methods FOXA3 mRNA expression in 31 CRC cancer tissues and their matched normal tissues was detec-ted by real-time quantitative PCR(RT-qPCR).The protein ex-pression of FOXA3 in 120 CRC cancer tissues was detected by immunohistochemical EnVision two-step method,and the clini-copathologic features such as lymph node metastasis and immu-nohistochemical expression were analyzed.Results The mRNA expression level of FOXA3 in colorectal cancer tissues was sig-nificantly higher than that in paired paracancer tissues(t=2.952,P=0.006 1).FOXA3 protein expression level in color-ectal cancer tissues was not significantly correlated with gender,age,site and size of patients,but significantly correlated with the degree of tissue differentiation(P=0.006)and lymph node metastasis(P=0.002).The degree of differentiation was nega-tively correlated with FOXA3 expression,while lymph node me-tastasis was positively correlated with FOXA3 expression.Sur-vival analysis showed that higher FOXA3 expression was associ-ated with worse overall survival(P＜0.000 1),and FOXA3 was an independent risk factor for prognosis in patients with colorectal cancer.Conclusion This study suggests that FOXA3 may play a promoting role in the occurrence and development of colorectal cancer,and FOXA3 may be a molecular marker for the diagnosis,metastasis and prognosis of colorectal cancer.
