Surgery Combined with Oncological Treatments in Liver Metastases from Colorectal Cancer

Abstract

The patients with colorectal liver metastases used to have a rather disappointing prognosis in the past. At present there is moderate possibility for cure with liver resection. In addition more patients are accessible for liver resection and potential cure when modern chemotherapy combined with biological agents is used. At the time of diagnosis liver metastases of 10–20% of patients are resectable. Potentially unresectable metastases can be converted to resectable in 10–15% of patients with advances in surgery together with improved oncological therapy. Resection rate increases linearly with the response rate to chemotherapy. In this century the 5-year survival rates after resection have improved remarkably being around 50% in many reports. Multidisciplinary management of metastatic colorectal cancer has increased the number of patients with potentially curative treatment and has improved patient survival.
