The need for a multidisciplinary approach in the treatment of advanced colorectal cancer: a critical review from a medical oncologist and surgeon.

Over the last 10 years important advances have been made in the treatment of patients with advanced colorectal cancer, particularly with surgery either alone or in combination with radiotherapy. Furthermore, despite early scepticism, several chemotherapy studies have now reported significant clinical benefits with 5-FU-based regimens and promising results have also been reported with newer agents such as raltitrexed and irinotecan. Taken together these advances now enable a significant proportion of patients to undergo treatment which will improve their quality of life, prolong survival and even result in cure in certain cases. Patients with advanced colorectal cancer can only benefit from these important advances, however, if a truly multidisciplinary approach to patient care is adopted which requires integration of the roles of the surgeon, medical oncologist and radiotherapist.
