title: [Surgical resection of liver metastases from colorectal carcinoma. Experience in Sant Pau Hospital].
abstract: BACKGROUND
  Surgical resection is the only available treatment that improves survival in patients with liver metastases from colorectal cancer, particularly when carried out by a multidisciplinary team.
  
  
  METHODS
  We retrospectively analyzed a consecutive series of 116 patients who underwent 138 liver resections (65.4% minor and 35.5% major) for hepatic metastases from colorectal cancer between 1998 and 2004. In 34.5% of the patients, the lesions were synchronous. All patients were individually assessed by a multidisciplinary team. The mean number of metastases removed per patient was 2.43 (range: 1-10). The mean size of the largest tumor per patient was 40 mm (range: 12-90). In 67.3% of the patients, the primary tumor was at an advanced stage (III-IV). In 98% of the patients, the diagnosis was confirmed by helical computed tomography scans/magnetic resonance imaging and intraoperative ultrasonography.
  
  
  RESULTS
  Postoperative morbidity was 31.2% and mortality was 2.2%. A mean of 2.7 units of blood was transfused per patient. Overall 5-year survival was 43.2% (median 50 months). Survival rates varied according to whether the patients had < 4 or > or = 4 colorectal liver metastases (50 and 43 months respectively), tumor size (more or less than 5 cm) (60 and 50.6 months respectively) and whether the site was monolobar or bilobar (60 and 43.11 months respectively). In 16 patients, recurrence of liver metastases led to 22 rehepatectomies. Overall 5-year survival was 36.7% (median 60 months) after the first rehepatectomy but was 36 and 12 months respectively after a second or third rehepatectomy.
  
  
  CONCLUSIONS
  These results confirm that multidisciplinary decisions and interventions by specialist liver surgeons, as in our hospital, reduce postoperative morbidity and mortality and increase survival in patients requiring surgical removal of liver metastases from colorectal cancer.
