摘　　要：AIM To assess the long-term prognostic value of vascular endothelial growth factor receptor 1(VEGFR1)and classⅢβ-tubulin(TUBB3)mRNA expression in nonmetastatic rectal cancer.METHODS A total of 75 consecutive patients with non-metastatic rectal cancer from March 2004 to November 2008 were analyzed retrospectively at our institute.The mRNA expressions of VEGFR1 and TUBB3 were detected by multiplex branched DNA liquid-chip technology.The Cutoff Finder application was applied to determine cutoff point of mRNA expression.SPSS software version 22.0was used for analysis.RESULTS The median follow-up was 102.7 mo(range,6-153.6).Theχ~2 and Fisher’s exact tests showed that VEGFR1expression was related to lymph node metastasis(P=0.013),while no relationships between TUBB3 and clinicopathological features were observed.Univariate analysis showed that T stage,lymph node metastasis,tumor differentiation,VEGFR1 and TUBB3 mRNA expression were correlated to overall survival(OS)(P=0.048,P=0.003,P=0.052,P=0.003 and P=0.015,respectively).Also,lymph node metastasis and VEGFR1expression independently influenced OS by multivariate analysis(P=0.027 and P=0.033).VEGFR1 expression was positively correlated with TUBB3(P=0.024).The patients with low expression of both TUBB3 and VEGFR1 presented a better OS(P=0.003).In addition,the receiver operating characteristic analysis suggested that the combination of lymph node metastasis and VEGFR1 had a more favorable prognostic value(P<0.001).CONCLUSION VEGFR1 expression and lymph node metastasis independently and jointly affect survival.Moreover,low expression of VEGFR1 and TUBB3 presented a better OS in patients with non-metastatic rectal cancer,which might serve as a potential prognostic factor.AIM To assess the long-term prognostic value of vascular endothelial growth factor receptor 1(VEGFR1)and classⅢβ-tubulin(TUBB3)mRNA expression in nonmetastatic rectal cancer.METHODS A total of 75 consecutive patients with non-metastatic rectal cancer from March 2004 to November 2008 were analyzed retrospectively at our institute.The mRNA expressions of VEGFR1 and TUBB3 were detected by multiplex branched DNA liquid-chip technology.The Cutoff Finder application was applied to determine cutoff point of mRNA expression.SPSS software version 22.0was used for analysis.RESULTS The median follow-up was 102.7 mo(range,6-153.6).Theχ~2 and Fisher’s exact tests showed that VEGFR1expression was related to lymph node metastasis(P=0.013),while no relationships between TUBB3 and clinicopathological features were observed.Univariate analysis showed that T stage,lymph node metastasis,tumor differentiation,VEGFR1 and TUBB3 mRNA expression were correlated to overall survival(OS)(P=0.048,P=0.003,P=0.052,P=0.003 and P=0.015,respectively).Also,lymph node metastasis and VEGFR1expression independently influenced OS by multivariate analysis(P=0.027 and P=0.033).VEGFR1 expression was positively correlated with TUBB3(P=0.024).The patients with low expression of both TUBB3 and VEGFR1 presented a better OS(P=0.003).In addition,the receiver operating characteristic analysis suggested that the combination of lymph node metastasis and VEGFR1 had a more favorable prognostic value(P<0.001).CONCLUSION VEGFR1 expression and lymph node metastasis independently and jointly affect survival.Moreover,low expression of VEGFR1 and TUBB3 presented a better OS in patients with non-metastatic rectal cancer,which might serve as a potential prognostic factor.
