Abstract:

Objective

To evaluate the value of CT-guided percutaneous radiofrequency ablation（RFA）therapy of lung tumours.

Methods

Thirty-two patients with pathologically proved lung neoplasms that comprised 28 primary lung cancers（total 28 lesions），4 metastases（total 10 lesions）initially underwent CT-guided percutaneous RFA treatment and subsequently the near-term efficacy.

Results

Our experiences have indicated an initial increase in lesion size at immediate follow-up CT.The density of 38 lesions was lowered.Among total 38 lesions of 32 patients，RFA resulted in necrosis of 38 lesions，which appears as devascularization and enhancement of residual tumors on postcontrast CT images.Measurement of the lestns were rediologrcally assessed on axial CT scan in the lung window setting，with the regult of no lenins had complete response，partial response 76.32%（29/38），lesions stable disease 10.53%（4/38），lesions showed progressive disease13.16%（5/38）at 3 month follow-up CT.No severe complications related to the procedure occurred in the group patients.

Conclusions

CT-guided percutaneous RFA in treating lung neoplasms is safe and effective，which has recently received wide attention for the promising results achieved，and can serve as a new approach to the treatment of lung neoplasm.
