Abstract

This debate examines the arguments for and against the proposal that surgical excision alone is adequate treatment for primary colorectal cancer. The arguments in faviour are that the results from curative surgery are excellent and that despite many trials of adjuvant chemotherapy, radiotherapy and immunotherapy, the proposed benefits remain unproven. Recent improvements in surgical technique, particularly for dissection of rectal tumours, have shown the way towards further improvement using surgery alone, and it is clear from a national survey that technical factors related to individual surgeons play a large part in determining recurrence rates. With optimum primary treatment, surgical excision alone is indeed adequate therapy. The arguments against this motion are that although a considerable number of patients do survive with surgery, the 5-year survival rate is poor when there is extensive local invasion of lymphatic metastases. Surgery starts therapy by reducing the tumour load, but other modalities are required to destroy the cells which might subsequently develop into metastases. Trial results with adjuvant therapy are encouraging, although many contain too few patients. We cannot be content with the results of treatment of Dukes' Stage B and C tumours; more trials are needed to determine the best treatment for these patients.
