title: [Combined treatment of inoperable liver metastases from colorectal cancer].
abstract: OBJECTIVE
  Liver resection improves survival in selected patients with colorectal liver metastases. However, the majority of patients with colorectal liver metastases have an inoperable oncological disease. The aim is to investigate whether intra-arterial infusion of chemotherapy, improves response to treatment and may convert a selected group of patients with irresectable liver metastases into an operable state.
  
  
  METHODS
  Thirty-sex patients (pts) with inoperable hepatic metastases from colorectal cancer were treated with intra-arterial chemotherapy, by angiographic technique. All patients underwent a short 5-FU-based locoregional infusion and the 13 non pretreated patients also received systemic therapy. Evaluation of response was made by CT scan.
  
  
  RESULTS
  Total cycles administered angiographically: 132 (range, 1-11). There were no complications associated with the angiographic procedure and no cases of > grade 2 toxicity. One heavily pretreated pt experienced moderate cholangitis and superficial gastric erosion. Thirty-one pts were assessable (20 pretreated and 11 not); there was 1 complete response (CR), 3 partial remissions (PR), 2 stabilizations (SD) among non-pretreated pts (6/11; CR + PR + SD = 55%) and 1 PR and 8 SD among pretreated pts (9/20; PR + SD = 45%). The remaining 16 pts progressed. Four pts became eligible for radical hepatic resection (1 refused surgery and 3 patients were operated on). There was no peri-operative deaths. Median survival of these 3 pts was 24, 28 and 39+ months.
  
  
  CONCLUSIONS
  Our data, even if based on a relatively small case series, appear to confirm effective local disease control in this clinical setting. Regional chemotherapy used singly or in combination with systemic chemotherapy may convert a selected group of patients with irresectable liver metastases to an oncological disease that can benefit from surgical treatment.
