[Colorectal liver metastases. Neoadjuvant chemotherapy: aspects of medical and surgical oncology].
Colorectal liver metastases are detected in 15-20% of patients at the time of diagnosis of the primary tumor, they develop in an additional 20-30% of patients during further course of the disease. Radical resection enables 5-year survival rates of 30-50%. Resectability may be increased by surgical techniques including two-stage hepatectomy and portal vein embolization. Furthermore, modern chemotherapy including various combinations of oxaliplatin, irinotecan, bevacizumab, and cetuximab has led to secondary resectability correlating to response rates which may be up to 80%. Changes of hepatic histology such as sinusoidal obstruction (e.g. following oxaliplatin) or steatohepatitis (e.g. following irinotecan) have been described. Individually, this may increase the risk of subsequent liver resection. As of today the role of neoadjuvant chemotherapy for resectable lesions has not been definitively confirmed.
