Computed Tomography Guided Radiofrequency Ablation of Lung Tumors with A Clustered Electrode:A Report of 36 Cases / 中国医师杂志

ABSTRACT

Objective To evaluate the efficacy of computed tomography guided radiofrequency(RF) ablation of non-small cell lung carcinoma with a clustered electrode.Methods 71 patients were allocated to 2 groupthe group A(36 patients) were undergone RF tissue ablation 38 times and analysed image data,tumor size before and after the procedure were compared,the group B(35 patients) were treated with the combined chemotherapy of "FAP" or "CAP".Results The group A thirty-six cases at 10 days,twenty at 30 days,fifteen at 60 days after the ablation,all patients were repeatedly examined by CT scans,respectively.The tumor size was decreased by 20% at 10 days in 69% patients,decreased by 30% at 30 days in 75% patients,decreased by 50% at 60 days in 53% patients and disappeared in 13%,no operative death was noted,the effective rates were 66% in group A and 22 9% in group B respectively(P
