Treatment of liver metastases from colorectal cancer with hepatic artery occlusion, intraportal 5-fluorouracil infusion, and oral allopurinol. A randomized clinical trial

Abstract

This study identified a treatment modality that prolongs survival in patients with nonresectable liver metastases and no extrahepatic metastases from colorectal cancer, suggesting that control subjects receiving no therapy may not be necessary in future randomized trials.
