title: Liver resection for metastatic colorectal cancer in the age of neoadjuvant chemotherapy and bevacizumab.
abstract: Hepatic metastases from colorectal carcinoma (CRC) were once thought to portend a uniformly grim outcome; however, improvements in chemotherapeutic and surgical approaches have led to significant advances as well as new clinical challenges. Some 60% of the 150,000 patients diagnosed with CRC each year in the United States will develop hepatic metastases. Only a fraction of these metastases are resectable at the time of presentation, but an increasing number of patients are able to undergo resection after neoadjuvant chemotherapy. Additionally, recent trials have demonstrated the efficacy of using chemotherapy with bevacizumab as first-line therapy for metastatic CRC, but how this treatment will affect surgical resection is unknown. Herein, we review the recent literature regarding neoadjuvant chemotherapy for hepatic metastases from CRC, discuss key aspects of the basic science of hepatic regeneration with regard to angiogenic mediators, and outline the key problems to be solved so that a rational strategy can be developed to treat patients with hepatic colorectal metastases in the age of neoadjuvant chemotherapy and antiangiogenic drugs.
