CT-guided radiofrequency ablation for the treatment of advanced non- small cell lung cancer:observation of clinical short-term efficacy / 介入放射学杂志

ABSTRACT

Objective To investigate the short-term efficacy of CT-guided radiofrequency ablation (RFA) for the treatment of advanced non-small cell lung cancer. Methods During the period from June 2010 to June 2013, a total of 100 patients with advanced non-small cell lung cancer were admitted to authors’ hospital. The patients were equally and randomly divided into the study group (n=50) and the control group (n=50). The patients of the control group received concurrent radiotherapy and chemotherapy treatment, while the patients of the study group received CT-guided RFA. The clinical effect, changes in CT values after the treatment, the improvement of physical condition and postoperative complications were recorded, and the results were compared between the two groups. Results The remission rate of the disease in the study group was 86.0%, which was much higher than that in the control group (52.0%), and the difference between the two groups was statistically significant (P<0.05). After the treatment, the CT value of the study group was (14.1±3.9) HU, which was significantly lower than that of the control group (29.8±4.7 HU, P<0.05). The physical improvement rate of the study group (66.0%) was significantly higher than that of the control group (44.0%), the difference between the two groups was statistically significant (P<0.05). The occurrence of postoperative complications, such as pulmonary infection, chest pain, fever, thoracic effusion and gastrointestinal reaction, in the study group was strikingly lower than that in the control group (P<0.05). Conclusion For the treatment of advanced non-small cell lung cancer, CT-guided radiofrequency ablation is safe and less-invasive, it can improve the clinical short-term effect as well as the quality of life. Therefore, this technique should be recommended in clinical practice.
