Metastasectomy for Stage IV Colorectal Cancer

Metastatic colorectal cancer traditionally has been considered incurable. Over the past 3 decades, however, resection of low-volume hepatic disease has been recognized as beneficial in some cases. More recently, resection of isolated pulmonary metastases has been shown to offer long-term survival in carefully selected patients. Resection of metastases to more unusual sites (ovary, brain, peritoneal cavity) is more controversial; nevertheless, retrospective data suggest that a few patients may be cured with resection of these tumors. In this article, we review the history and current status of metastasectomy in stage IV colorectal cancer.
