title: [Liver metastasis: therapeutic strategy].
abstract: The liver is one of the most frequent sites of metastatic growth, in particular from digestive malignancies (DM). The first goal is to reduce the incidence of metastases. Adjuvant systemic chemotherapies have been demonstrated to reduce the recurrence rate and to improve survival in Dukes C colon cancer. Fluorouracil is the pivot of adjuvant treatment modulated by Leucovorin or Levamisol. A short postoperative administration of fluorouracil by intraportal route has been tested, but the results are controversial. Adjuvant treatments for different DM are under investigation. When hepatic metastases are clinically evident, therapeutic decisions depend on several factors: site and nature of primary, extent of hepatic and extrahepatic disease, patient characteristics, efficacy of treatments. A staging system should be adopted to allow a rational approach. In selected cases a locoregional treatment can achieve consistent results. Hepatic Intrarterial Chemotherapy (HIAC) for colorectal metastases achieves objective responses in more than 50% of patients. Survival seems positively affected. When feasible, Ro hepatic resection is the most effective treatment, five-year survival rate being about 30% when metastases are from colorectal cancer. Since the liver is the most frequent site of recurrence after resection, repeat resection have been successfully performed.
