Background Previous studies have documented the therapeutic value of computed tomography (CT)-guided percutaneous microwave ablation (MWA) for early-stage non-small cell lung cancer (NSCLC). However, few studies have focused on patients aged 80 years and older. This retrospective study aimed to evaluate the safety and clinical outcomes of CT-guided percutaneous MWA in patients aged 80 years and older with early-stage peripheral NSCLC. Methods A retrospective analysis of 63 patients aged 80 years and older with cT1a-2bN0M0 peripheral NSCLC who underwent CT-guided percutaneous MWA was performed between January 2008 and January 2018 at 11 hospitals in Shandong Province, China. Results The median follow-up time was 21.0 months. The overall median survival time was 50 months. The cancer-specific median survival time was not reached in five years. The one-, two-, three-, four-, and five-year overall survival rates were 97.1%, 92.6%, 63.4%, 54.4%, and 32.6%, respectively. The one-, two-, and three-year cancer-specific survival (CSS) rates were 97.9%, 97.9%, and 69.4%, respectively. The four- and five-year CSS rates were not achieved. A total of 14 patients (22.2%) had local progression. The one-, two-, three-, four-, and five-year local control rates were 88.8%, 78.8%, 70.3%, 63.9%, and 63.9%, respectively. The mortality rate was 0% within 30 days after the procedure. Major complications included pneumothorax requiring drainage (21.1%), pulmonary infection (4.2%), and pleural effusions requiring drainage (2.8%). Conclusions CT-guided percutaneous MWA is a safe and effective modality for treating patients aged 80 years and older with early-stage peripheral NSCLC.
