ABSTRACT
Objective To evaluate the safety,local efficacy and survival rates of isolated pulmonary metastases from colorectal carcinoma treated with CT-guided radiofrequency ablation.Methods A total of 28 patients with isolated pulmonary metastases from colorectal carcinoma were performed with CT-guided radiofrequency ablation (radiofrequency ablation group).The size of the lesion was 1.2-5.0 (2.9 ± 1.0) cm.During the same time,9 patients,who did not take any treatment for isolated pulmonary metastases from colorectal carcinoma,were collected as control group.The size of the lesion was 2.0-5.0 (3.6 ± 1.0) cm.The local progression-free rates and overall survival rates were compared.Results All the cases were able to complete the radiofrequency ablation in radiofrequency ablation group.During and after the procedure,no major complications occurred.The 1-,2-,and 3-year local progression-free rates and overall survival rates in radiofrequency ablation group were significantly higher than those in control group.The local progression-free rates were 89.3% vs.76.2%,78.6% vs.33.9%,70.7% vs.16.9%.The overall survival rates were 96.4% vs.77.8%,85.7% vs.44.4%,56.7% vs.22.2%.The differences between two groups had statistical significance (P < 0.01).Conclusion CT-guided radiofrequency ablation for isolated pulmonary metastasis from colorectal carcinoma is a safe,effective,minimally invasive treatment,and can significantly improve the local progression-free rates and overall survival rates.
