Chemotherapy, Liver Injury, and Postoperative Complications in Colorectal Liver Metastases.
Summary of "Chemotherapy, Liver Injury, and Postoperative Complications in Colorectal Liver Metastases."
Systemic chemotherapy (CTx) is increasingly used before surgery for colorectal liver metastases (CRC-LM). However, CTx may cause liver injury like steatosis, steatohepatitis, and sinusoidal injury which may be associated with postoperative morbidity. Some recent data have even shown an increased mortality in patients with CTx-associated steatohepatitis. We, therefore, analyzed our recent experience with potential hepatic injury and its association with CTx and morbidity in patients undergoing surgery for CRC-LM.
From 2001 to 2007, 179 patients underwent primary liver resection for CRC-LM. Sufficient non-tumorous liver parenchyma could be re-evaluated for this study in 102 patients. In these 102 patients (66% male, median age 62 years, median BMI 26, 8% diabetics (IDDM)), liver injury was classified using established criteria for steatosis and sinusoidal dilatation (SD) and then compared with preoperative CTx and postoperative outcome. Fifty-eight percent of the operations were (extended) hemihepatectomies (ExtRes), 42% segmental or wedge resections (LimRes). Before resection, 66% had received CTx (33% FU-based (FU), 19% oxaliplatin-based (Oxa), 12% irinotecan-based (Iri), and 3% Oxa+Iri). The interval between CTx and surgery was always ≥4 weeks.
Mortality was 3/102 (2.9%). Any complication occurred in 48%, hepatic insufficiency in 5.9%, and liver-related complications in 24%. Hepatic steatosis >20% was found in 37% (half of them with steatosis >50%). BMI correlated with the frequency of steatosis. Steatosis >20% was more frequent in patients with preoperative chemotherapy but did not depend on the chemotherapy regimen. No relevant risk factor for grades 2 and 3 SD was found. The specific use of Oxa or Iri did not significantly correlate with hepatic injury. Neither a CTx per se nor the different CTx regimens nor the extent of hepatic injury showed any negative influence on mortality, complication rates, or hepatic insufficiency. Patients with IDDM had a higher mortality (25% vs 1% without IDDM; p < 0.02), increased complication rate (75% vs 46%; p = 0.11), a higher rate of hepatic insufficiency (25% vs 4%; p < 0.02), and more liver related complications (50% vs 21%; p = 0.06). Patients undergoing ExtRes had a higher overall (p < 0.01) and liver-related (p = 0.05) complication rate compared to LimRes. None of the 34 patients with preoperative Oxa or Iri died or developed hepatic insufficiency.
In our experience, hepatic injury (steatosis) was influenced by BMI and by preoperative CTx. Neither preoperative CTx nor liver injury increased perioperative morbidity. Patients with IDDM were at a rather high perioperative risk.

The primary objective was to compare overall survival (OS) in patients with colorectal cancer (CRC) with nonresectable liver-only metastases treated by liver transplantation or chemotherapy.
70 years ago, it was put forward that the diseased liver was not a favorable soil for metastatic tumor cells. In addition, a few studies have demonstrated that rare occurrence of colorectal liver meta...

Hypothesis of the study: Neoadjuvant chemotherapy with Bevacizumab impairs postoperative outcome after resection of colorectal liver metastases.
The aim of the study is to obtain information on FLT used in a PET-scan as a marker for the proliferation of colorectal liver metastases, so that the risk of recurrence can be identified i...

Medical and Biotech [MESH] Definitions
A spectrum of clinical liver diseases ranging from mild biochemical abnormalities to ACUTE LIVER FAILURE, caused by drugs, drug metabolites, and chemicals from the environment.
A form of rapid-onset LIVER FAILURE, also known as fulminant hepatic failure, caused by severe liver injury or massive loss of HEPATOCYTES. It is characterized by sudden development of liver dysfunction and JAUNDICE. Acute liver failure may progress to exhibit cerebral dysfunction even HEPATIC COMA depending on the etiology that includes hepatic ISCHEMIA, drug toxicity, malignant infiltration, and viral hepatitis such as post-transfusion HEPATITIS B and HEPATITIS C.
Final stage of a liver disease when the liver failure is irreversible and LIVER TRANSPLANTATION is needed.
Experimentally induced chronic injuries to the parenchymal cells in the liver to achieve a model for LIVER CIRRHOSIS.
Conditions in which the LIVER functions fall below the normal ranges. Severe hepatic insufficiency may cause LIVER FAILURE or DEATH. Treatment may include LIVER TRANSPLANTATION.
