title: Hepatic arterial infusion chemotherapy in sarcoma liver metastases: a report of 6 cases.
abstract: OBJECTIVE
  Liver metastases in patients with sarcoma are rare and associated with a poor prognosis. The experience with liver-directed therapies, eg hepatic arterial infusion, in these patients is limited.
  
  
  METHODS
  Six patients with sarcoma metastatic to the liver (4 patients with gastrointestinal stromal tumors and 2 patients with leiomyosarcoma) were treated by hepatic arterial infusion in our center over a 12-year period. Since the experience was limited, a pooled analysis of reports with data on survival of 22 individual patients was performed.
  
  
  RESULTS
  None of the 5 assessable patients responded to the therapy, and liver metastases progressed in all patients. The median survival was 20 months. In the pooled analysis, partial response was observed in 10 of 21 assessable patients (48%) and median survival was 20 months. The survival was significantly longer in responding patients compared to nonresponders (35 vs 14 months; logrank test, P = 0.009).
  
  
  CONCLUSIONS
  Hepatic arterial infusion has little efficacy in the treatment of sarcoma metastatic to the liver. More promising results have been reported for chemoembolization. The survival of responding patients seems to be better compared to non-responders.
