Abstract
Discrepancies in morbidity and local recurrence rates in published clinical trials of pelvic XRT for colorectal cancer are caused by a variety of complex factors. It is, however, clear that XRT is able to cure early rectal carcinomas and is particularly useful in alleviating the symptoms of advanced or recurrent disease. The selection of appropriate cases for combinations of XRT and surgery can be made on the basis of digital examination under anaesthetic. One aim of these combinations is to reduce the number of patients with mobile tumours of the lower two-thirds of the rectum who require a permanent colostomy. In the absence of effective chemotherapy for metastatic disease, liver XRT may have a place in controlling the growth rate of occult liver metastases in selected patients.
