Liver Infusions of Fluorouracil in Treating Patients With Dukes’ A, Dukes’ B, or Dukes’ C Colon Cancer Undergoing Surgery

RATIONALE: Drugs used in chemotherapy, such as fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether giving fluorouracil into the liver is more effective than no further treatment for patients with colon cancer undergoing surgery.
PURPOSE: This randomized phase III trial is studying giving infusions of fluorouracil into the liver in treating patients with Dukes’ A, Dukes’ B, or Dukes’ C colon cancer undergoing surgery.
