OBJECTIVE: To investigate the effects of preoperative hepatic and regional arterial infusion chemotherapy (PHRAIC) in the prevention of liver metastasis of colorectal cancer after surgery. METHODS:110 patients of colorectal cancer underwentperfusion of 3 anti-tumor drugs into the hepatic artery and nutrient artery of the tumor respectively, radical surgery of the colorectal cancer 7 days after, and then general venous chemotherapy 3 weeks after operation, 112 patients underwentradical surgery of the colorectal cancer and general venous chemotherapy 3 weeks after operation. Follow-up was carried out every month with a follow-up period of 34 months +/- 3 months. RESULTS: There were no significant difference in post-operational complications between these 2 groups. The 3-year liver metastasis rate, 3-year tumor-free survival rate, overall survival rate, and median survival time of the stage III patients in the PHRAIC group were 12.7%, 82.3%, 87.7%, and 40 months +/- 5 months, all significantly better than those in the control group (28.3%, 58.7%, 75.5%, and 36 months +/- 3 months respectively, P < 0.05 or P < 0.01). CONCLUSION: PHRAIC reduces the liver metastasis of colorectal cancer after radical surgery and improves the survival of the stage III patients.
