3D-CT guided percutaneous radiofrequency ablation against advanced lung cancer: short term effect assessment / 肿瘤研究与临床

ABSTRACT

Objective Under the guidance of CT and three dimensional reconstruction, we made therapeutic plan for lung cancer by radiofrequency ablation (RFA) and observed its effect. Methods From February 2007 to January 2009, we used RITA radiofrequency therapeutic equipment to treat lung cancer under the guidance of 64-slice spiral CT (Siemens) and three dimensional reconstruction of the image. The target temperature is 90℃. Results We performed 29 RFA on 25 patients. In the follow-up, 10 of them showed tumor shrinkage by CT scan. 23 showed lack of tumor-uptake value by SPECT scan and 2 showed lower tumor-uptake value. Conclusion CT-guided percutaneous RFA is safe and practical for lung cancer. It has satisfactory short-term effect to reduce tumor burden.
