Factors that influence treatment strategies in advanced colorectal cancer.

This review focuses on the factors that now influence our treatment strategies designed to increase the pool of patients with colorectal liver metastases for whom curative treatment may be possible. These strategies include improved preoperative staging techniques, new standards for surgical resection, novel surgical strategies, the application of modern systemic chemotherapy in a neoadjuvant setting, an emerging role for ablative therapies and an emphasis on the collaborative, a reappraisal of staging advanced disease, multidisciplinary management, and defining the role of the patient in managing their disease. It is now clear that an aggressive multi-disciplinary approach to the management of this problem will lead to nearly one third of these patients being considered for treatment that even if not achieving complete cure, offers significant long-term survival.
