RESUMEN
To evaluate the value of chemotherapy via portal vein pump implantation in preventing hepatic metastasis from colorectal cancer after a radical resestion. Patients after a radical resection were divided into two groups: the portal vein pump implantation chemotherapy group (Group A 32 cases), chemotherapy via peripheral vein(Grounp B 22 cases). The results showed that hepatic metastasis rate was 15 4% in group I and 36 4% in group 2. The survival rates of 1, 2, 3 years in group A were 98%, 83%, 61% respectively, while in group B they were 90%, 68%, 42%, respectively. The results suggested that portal vein pump chemotherapy was an effective treatment modality to prevent hepatic metastasis from colorectal cancer. Its clinical results were better than conventional chemotherapy via peripheral vein.
