CHEMOTHERAPY VIA HEPATIC ARTERY AND PORTAL VEIN FOR THE PREVENTION OF LIVER METASTASIS OF COLORECTAL CANCER / 解放军医学杂志

ABSTRACT

Objective To evaluate the clinical effect of chemotherapy via both hepatic artery and portal vein on liver metastasis of colorectal cancer. Methods Forty-eight patients with colorectal cancer (admitted to our hospital from Jan, 1994 to Dec, 2000)were divided into group Ⅰ, in which 17 patients received chemotherapy via both hepatic artery and portal vein, group Ⅱ in which 16 patients received simple hepatic artery chemotherapy, and group Ⅲ in which 15 patients received simple portal vein chemotherapy. Chemotherapy was begun 2 weeks after operation. The drugs used in chemotherapy regime were 5-fluorouracil(5-FU) 500mg/m 2 + Mitomycin(MMC) 4mg/m 2 + Epirubicin(EPI) 60mg/m 2, once per week, 2-3 times as a course. The chemotherapy regime was the same for the 3 groups. Results The respective effective rate for liver metastasis was 76.5%, 62.5%, 46.7% in group Ⅰ, group Ⅱ, and group Ⅲ. The 0.5, 1 and 2 year survival rates were 100%, 82.4% and 52.9% respectively in group Ⅰ, 87.5%, 62.5% and 43.7% respectively in group Ⅱ, and 93.3%, 60% and 33.3% respectively in group Ⅲ. There were statistically significant differences between group Ⅰ and groups Ⅱ and Ⅲ (P
