Abstract:
Objective To investigate the efficacy and prognostic factors of percutaneous ultrasound-guided radiofrequency ablation (RFA) for liver metastases from gastric cancer.Methods Clinical and imaging data of 55 patients with liver metastasis from gastric cancer who underwent percutenous ultrasound-guided RFA were retrospectively analyzed,and the overall survival rates and prognostic factors were assessed.Results The overall survival rates of 1-,2-,3-and 5-year was 70.45％,42.90％,20.32％ and 10.16％,respectively.The ablation rate was 94.12％ (96/102) 1 month after RFA,and the local recurrent rate was 15.69％ (16/102),the new metastasis rate was 52.73％ (29/55).Age (P=0.015),tumor number (P=0.011),extrahepatic metastasis before RFA (P=0.026) and chemotherapy after RFA (P=0.031) were significantly prognostic factors.Age (P=0.033),tumor number (P=0.004) as well as chemotherapy after RFA (P=0.001) were independent prognostic factors.The severe complication rate was 1.82％ (1/55),while no treatment-related death occurred.Conclusion Percutaneous ultrasound-guided RFA is a safe and effective therapeutic option for liver metastases from gastric cancer.Age,tumor number,chemotherapy after RFA are independent prognostic factors.
