Study Comparing Radio Frequency Ablation Plus Chemotherapy and Chemotherapy Alone in Patients With Unresectable CRLM

A Prospective, Randomized, One-center Study Assessing Overall Survival Using RFA Plus Chemotherapy ± Target Therapy and Chemotherapy ± Target Therapy Alone in Patients With Unresectable Unresectable Colorectal Cancer Liver Metastases

To date no prospective trials have been completed that demonstrated whether RFA is an effective adjunct to systemic chemotherapy (target therapy) with respect to advantages in overall survival compared with chemotherapy (target therapy) alone. The primary objective of this trial is to determine overall survival for patients with colorectal cancer liver metastasis are treated with radiofrequency ablation plus chemotherapy ± target therapy, compared to chemotherapy ± target therapy only.

Inclusion Criteria:

All patients must meet the following criteria:

Patients is medically eligible to receive RFA, as determined by the MDT (multidisciplinary team)

Eastern Cooperative Oncology Group (ECOG) Performance Status 0 or 1

Age > 18 years

Subject life expectancy > 3 months

Platelets > 100×103/mm3

Total bilirubin <1.5mg/dl

Creatinine level < 2.0 mg/dl

All patients must sign an informed consent form

Exclusion Criteria:

The CRLM is amenable to curative surgical therapy

Uncorrectable coagulopathy

Subject is pregnant, nursing, or wishes to become pregnant during the study

Other serious medical condition (uncontrolled infection, uncontrolled cardiac disease) would preclude study treatment or impact survival

Current or planned treatment with any experimental chemotherapy or target drugs
