Abstract:
Objective To determine serum vascular endothelial growth factor (s-VEGF) and serum endostatin (s-endostatin) levels in patients with colorectal cancer after preoperative regional intraarterial chemotherapy (PRAC). Methods Peripheral venous blood was sampled preoperatively and postoperatively, and was assayed for VEGF and endostatin by ELISA. Results Patients' preoperative level of s-VEGF and s-endostatin elevated significantly, which was in close correlation with Dukes' stage. The level of s-VEGF and s-endostatin before chemotherapy elevated significantly compared with that on day 7 after chemotherapy and on postoperational day 1 and 14 after operation. In patients undergoing palliative resection, only the level of s-endostatin before chemotherapy was significantly higher than that on day 1 after operation. Conclusions PRAC, inhibiting angiogenesis, is of antitumor effect, the decrease of s-endostatin after chemotherapy may suggest the combination of chemotherapy and antiangiogenesis for a better antitumor effect.
