BACKGROUND AND AIMS: Neoadjuvant chemotherapy is increasingly being used to enlarge the cohort of patients who can be offered hepatic resection for malignancy. However, the impact of these agents on the liver parenchyma itself, and their effects on clinical outcomes following hepatic resection remain unclear. This review identifies patterns of regimen-specific chemotherapy-induced hepatic injury and assesses their impact on outcomes following hepatic resection for colorectal liver metastases (CLM). METHODS: An electronic search was performed using the MEDLINE (US Library of Congress) database from 1966 to May 2007 to identify relevant articles related to chemotherapy-induced hepatic injury and subsequent outcome following hepatic resection. RESULTS: The use of the combination of 5-flourouracil and leucovorin is linked to the development of hepatic steatosis, and translates into increased postoperative infection rates. A form of non-alcoholic steatohepatitis (NASH) related to chemotherapy and otherwise known as chemotherapy-associated steatohepatitis (CASH) is closely linked to irinotecan-based therapy and is associated with inferior outcomes following hepatic surgery mainly due to hepatic insufficiency and poor regeneration. Data on sinusoidal obstruction syndrome (SOS) following treatment with oxaliplatin are less convincing, but there appears to be an increased risk for intra-operative bleeding and decreased hepatic reserve associated with the presence of SOS. Intra-arterial floxuridine therapy damages the extrahepatic biliary tree in addition to causing parenchymal liver damage, and has been shown to be associated with increased morbidity after hepatic resection. CONCLUSION: Agent-specific patterns of damage are now being recognized with increasing use of neoadjuvant chemotherapy prior to surgery. The potential benefits and risks of these should be considered on an individual patient basis prior to hepatic resection.
