RT Journal Article SR Electronic T1 Adjuvant therapy for colorectal cancer JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 603 OP 607 VO 59 IS 6 A1 Vernava, Anthony M. YR 1992 UL http://www.ccjm.org/content/59/6/603.abstract AB The search for effective adjuvant therapy for colorectal cancer has been long and, until recently, largely unrewarding. Surgery alone is inadequate therapy in as many as 5 0 % of patients. But recent studies demonstrate significant improvement in disease-free survival and overall survival for patients with advanced colon and rectal cancer who receive adjuvant therapy. Postoperative chemotherapy with fluorouracil and levamisole is the standard of care for patients with stage III colon cancer, and postoperative high-dose pelvic radiation combined with fluorouracil is the standard regimen for patients with stage II and III rectal cancer.
