ADJUVANT THERAPY FOR COLORECTAL-CANCER - IS THERE A PLACE FOR A NORTHERN-IRELAND STUDY

Survival from colorectal cancer has not improved over the last four decades despite advances in surgery and anaesthesia. The answer to the question whether adjuvant chemotherapy and radiotherapy will improve survival from the disease can only come from randomised, controlled trials. In the future, immunotherapy and gene therapy may be of benefit but these are still many years from the clinical arena. We believe that current evidence suggests that patients with Dukes' B and C colorectal cancer should be entered into trials of adjuvant therapy. This evidence is reviewed below along with estimates of the impact that adjuvant therapy would have on the outcome from this disease in Northern Ireland.
