title: [Treatment efficacy of surgical management for liver metastasis from colorectal cancer--a report of 198 cases].
abstract: OBJECTIVE
  Liver is the most common site of metastasis in colorectal cancer, and 35% patients with colorectal cancer developed liver metastasis at diagnosis. The prognosis of the patients with liver metastases from colorectal cancer is poor. Surgical resection, radiofrequency ablation, and chemotherapy had been used in clinical treatment for liver metastasis from colorectal cancer with various outcomes. This study was to explore the treatment efficacy of surgical management for liver metastasis from colorectal cancer.
  
  
  METHODS
  Clinical data of 198 patients with liver metastasis from colorectal cancer, treated from Jan. 1995 to Jan. 2000, were studied retrospectively. Of the 198 patients, 46 (23.2%) received radical resection, 43 (21.7%) received palliative resection, 29 (14.6%) received exploratory operation or supportive treatment, 41 (20.7%) received adjuvant hepatic arterial infusion, and 39 (19.7%) received adjuvant systemic chemotherapy. Survival statuses of the patients in different groups were compared.
  
  
  RESULTS
  The median survival time of radical resection group was significantly longer than those of palliative resection group, exploratory operation or supportive treatment group, adjuvant hepatic arterial infusion group, and adjuvant systemic chemotherapy group (37.1 months vs. 14.3, 6.3, 21.3, and 18.7 months, P<0.01). The 5-year survival rates of the 5 groups were 31.2%, 0, 0, 7.5%, and 0, respectively.
  
  
  CONCLUSIONS
  Radical resection could improve survival of the patients with liver metastasis from colorectal cancer. Palliative resection has no advantage over adjuvant therapy. Adjuvant hepatic arterial infusion should be applied in the unresectable cases.
