title: Hepatic arterial infusion chemotherapy through a port-catheter system as preoperative initial therapy in patients with advanced liver dysfunction due to synchronous and unresectable liver metastases from colorectal cancer.
abstract: OBJECTIVE
  We retrospectively evaluated the safety and efficacy of preoperative initial hepatic arterial infusion chemotherapy (HAIC) through a port-catheter system in patients with liver dysfunction due to synchronous and unresectable liver metastases. The aim of HAIC was to improve patients' clinical condition for later surgical removal of primary colorectal cancer.
  
  
  METHODS
  Port-catheter systems were placed radiologically in 21 patients (mean age 58.6 +/- 8.1 years) with liver dysfunction due to synchronous liver metastases from colorectal cancer. Initial HAIC of 1,000 mg/m(2) 5-fluorouracil was administered weekly as a 5 hr continuous infusion through this system. Surgical removal of the primary lesion was planned after HAIC improved the liver function.
  
  
  RESULTS
  Port-catheter system placement was successful in all patients without severe complications. Patients were followed up for a median of 309 days (range 51-998 days). After starting HAIC, no severe adverse events that caused drug loss and treatment postponement or suspension were observed in any of the patients. HAIC was performed a mean of 4.5 +/- 3.0 times and the liver function improved in all patients. Curative (n = 18) or palliative (n = 1) surgical removal of the primary lesion was performed. The remaining 2 patients died because extrahepatic metastases developed and their performance status worsened; thus, surgery could not be performed. The median survival times of all patients and the operated patients were 309 and 386 days, respectively.
  
  
  CONCLUSIONS
  Initial HAIC administration is a safe and efficacious method for improving liver function prior to operative resection of primary colorectal cancer in patients with liver dysfunction due to synchronous and unresectable liver metastases.
