Follow-up after colorectal cancer--current practice in Wales and south west England.

The necessity for follow-up after curative resection of colorectal cancer remains controversial. Many studies have failed to demonstrate the increase in survival which might be anticipated when detailed follow-up methods are used. In the United Kingdom no single policy has evolved. This study has examined, therefore, the current follow-up practice of a large group of British surgeons. Six per cent carried out no routine postoperative follow-up and there was great variation in the methods used and the regularity of visits. There is a need for a rational policy based on controlled studies to determine whether follow-up is of benefit to the patient and to identify the most effective methods.
