title: Repeat liver resection for recurrent liver metastases from colorectal cancer.
abstract: OBJECTIVE
  Numerous patients suffer from recurrence after resection of liver metastases from colorectal cancer. Recurrence is frequently restricted to the liver and repeat liver resection may offer a curative option in these patients. This study was conducted to clarify safety and effectiveness of this treatment and to identify prognostic factors of a favourable outcome after repeat hepatectomy.
  
  
  METHODS
  Between January 1988 and March 2006 in our institution 811 patients underwent 841 liver resections for metastases from colorectal cancer. Among these, 94 patients underwent a repeat hepatectomy. Patients were identified from a prospective database and retrospectively reviewed. Results of different time periods were assessed and prognostic factors for a favourable outcome were determined.
  
  
  RESULTS
  The perioperative morbidity and mortality was 24% (23 of 94) and 3% (3 of 94), respectively. The one-, three-, five- and ten-year survival for all patients in this series was 89%, 55%, 38% and 23%, respectively. In the univariate analysis, pT-stage of the primary, diameter of the largest metastases, surgical radicality, period of resection and distribution of metastases showed statistically significant influence on survival. The multivariate analysis revealed only pT-stage of the primary tumour, surgical radicality and period of resection as independent prognostic factors.
  
  
  CONCLUSIONS
  Repeat hepatectomy is a safe and effective treatment for recurrent liver metastases from colorectal cancer. Perioperative risk and long-term survival were similar when compared to the results obtained during the initial resection. Achieving a curative resection is the most relevant prognostic factor for a favourable prognosis after repeat liver resection.
