Primary Outcome Measures:
  • Correlation of overall objective responses evaluated by conventional imaging techniques with the morphologic response evaluated by MDCT and the histopathologic response after the resection of hepatic metastases. [ Time Frame: 2016 ] [ Designated as safety issue: No ]

Patients with the diagnosis of liver metastasis presenting synchronically or after a disease-free interval. The primary tumor shall have been resected previously although the inverse approach may be acceptable if the tumor is not very symptomatic. Patients in whom combined surgery of the primary tumor and metastases is planned are not eligible.
