目的 用CT评价集束电极射频治疗肺癌的近期效果。方法 对 31例肺癌 34个病灶手术前、后肿瘤大小、密度及并发症进行观察。结果 射频治疗后 5min 79% (2 7/ 34)的肺癌病灶增大 ,2 1% (7/ 34)大小无变化。 <5cm的肿瘤密度增高 ,>5cm的肿瘤密度均减低 ;2个月后 17例复查 ,6 4% (11/ 17)病灶较原病灶缩小 ,18% (3/ 17)病灶较术前增大 ,18% (3/ 17)病灶大小无变化 ,肿瘤的CT值均减低约 2 0Hu左右。结论 CT可准确评价集束电极射频治疗后肺癌的病理变化。
Objective To evaluate the short-term effect of radiofrequency ablation of cluster electrodes on lung cancer with CT. Methods Tumor size, density and complications of 31 lesions of lung cancer before and after surgery were observed. Results Five minutes after radiofrequency treatment, 79% (27/34) lung cancer lesions were enlarged and 21% (7/34) in size did not change. The tumor density of <5 cm increased and the tumor density of> 5 cm decreased. After 2 months, 17 cases were reviewed. Sixty-four percent (11/17) lesions were reduced compared with the original lesions and 18% (3/17) lesions were increased , 18% (3/17) no change in the size of the lesion, the tumor CT values were reduced about 20Hu or so. Conclusions CT can accurately evaluate the pathological changes of lung cancer after radiofrequency ablation with cluster electrodes.
