Radiofrquency Ablation Combined With Cytokine-induced Killer Cells for Colorectal Cancer Liver Metastases

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine whether combining of radiofrequency ablation (RFA) and cytokine-induced killer cells (CIK) transfusion can prolong survival of patients with colorectal cancer liver metastases (CRCLM).

Detailed Description
-----------------
The primary objective is to evaluate whether RFA followed by CIK transfusion can prolong survival of patients with resectable CRCLM.
