During the 1980s, the only drug routinely used to treat colorectal carcinoma was single-agent fluorouracil (5-FU), a drug that had shown no proven benefit in the adjuvant setting. Since then, significant improvements in the overall management of colorectal cancer have been made. This review will compare today's standard of care for adjuvant colorectal carcinoma to that practiced 20 years ago. The authors examine key questions asked about adjuvant therapy and the answers that ultimately changed clinical practice standards and improved overall survival for patients diagnosed with this disease. In addition, this review explores whether 5-FU should be given as part of a multidrug regimen and which route of administration is best when this drug is given. Further, the authors delve into both the use of locally directed therapies to the liver or peritoneum to improve outcomes and the selection of patients to receive adjuvant chemotherapy. Finally, a look to the future shows monoclonal antibodies to be an avenue of great promise in fighting colorectal cancer.
