UNASSIGNED: This study evaluated the clinical efficacy and value of computed tomography (CT)-guided percutaneous microwave ablation therapy (PMAT) for @entity2 without surgical treatment. A total of 39 lesions in 29 @entity1 with @entity2 were treated by CT-guided PMAT under local anesthesia. The microwave energy was 50-70 W at a frequency of 2450 MHz. The treatment was performed by using 1 or 2 points of ablation emission according to the size and shape of the @entity5 . Operations were completed in 29 @entity1 . The average operating time was 8 min (range: 5-12 min). After PMAT, lower density in the ablated area was observed by CT. Pre- and post-treatment CT values were 52.60 and 26.12 Hu, respectively. Eight, 14, 4, and 3 @entity1 achieved complete remission, partial remission, stable status, and progression, respectively, for an effectiveness rate of 75.86%. Complications included 5, 2, and 15 cases of pneumothorax, @entity1143 , and fever, respectively. No needle track implantation was observed. Mean progression-free survival was 14.6 months. The 1- and 2-year survival rates were 91.3 and 82.6%, respectively. Thus, PMAT is a minimally invasive, safe, and effective treatment for @entity2 . It can improve quality of life, prolong survival, and improve the survival rate.
