Abstract:
Objective To investigate the relationship between vascular endothelial growth factor C (VEGF-C) and lymphatic vessel density (LVD) with clinicopathological features of the patients in stage Ⅱ colorectal cancer.Methods Fifty-seven tissues in stage Ⅱ colorectal cancer and 57 normal mucosal tissues in Shaanxi Provincial Cancer Hospital from January 2005 to December 2010 were collected.The expression of VEGF-C and LVD were detected by using immunohistochemical method.The relationship between VEGF-C and LVD with the clinicopathological features of colorectal cancer was analyzed.Results The expression of VEGF-C and LVD in cancer tissues was higher than that in normal tissues (6.80±1.24 vs.2.07±0.17,t =3.773,P =0.000;3.19±0.53 vs.1.84±0.26,t =2.276,P =0.025).There were statistical differences between VEGF-C and LVD in different tumor diameter (4.00±0.54 vs.11.26±2.89,t =-3.049,P =0.004;1.89±0.37 vs.5.27±1.12,t =-3.376,P =0.001) and relapse or metastasis (4.74±1.31 vs.10.62 ±2.39,t =-2.158,P =0.039;1.86±0.45 vs.5.65±1.06,t =-3.778,P =0.000).LVD in VEGF-C positive group was higher than that in VEGF-C negative group (4.16±0.64 vs.0.21±0.11,t =3.503,P =0.001).The expression of VEGF-C was positively correlated with LVD (r =0.892,P =0.000).Conclusions The expression of VEGF-C in stage Ⅱ colorectal cancer is correlated with LVD,as well as tumor size and relapse or metastasis.VEGF-C and LVD could also play important roles in the occurrence,development and metastasis in stage Ⅱ colorectal cancer.
