Microwave Ablation Effective for Elderly Patients with Non-Small Cell Lung Cancer

Research on non-small cell lung cancer (NSCLC) has shown that microwave ablation (MWA) is an effective treatment option for elderly patients with stage I NSCLC. According to a recent study published in Cancer Imaging, the efficacy of MWA for patients aged 75 years with stage I NSCLC was evaluated, and the impacts of age and comorbidities on long-term outcomes were explored. The study found that MWA had no significant differences in efficacy compared to younger patients, and age and Charlson comorbidity index (CCI) were not significant factors associated with prognosis.

Key Takeaways:

  • MWA is an efficacious tool for patients aged 75 years with stage I NSCLC, with 95.7% overall survival at 1 year, 82.6% at 3 years, and 72.8% at 5 years.
  • There were no significant differences in efficacy between patients aged 75 years and younger patients, with p-values of 0.212, 0.661, and 0.537 for overall survival, cancer-specific survival, and recurrence-free survival, respectively.
  • Age and CCI were not significant factors associated with prognosis, while idiopathic pulmonary fibrosis (IPF)/chronic obstructive pulmonary disease (COPD) was an independent risk factor.
  • The study concluded that MWA is an effective treatment option for elderly patients with stage I NSCLC, with no significant differences in efficacy compared to younger patients.

Statistics:

  • 138 patients were successfully matched, with 69 in each group.
  • The 1-, 3-, and 5-year overall survival rates were 95.7%, 82.6%, and 72.8% in patients aged 75 years, and 97.1%, 89.9%, and 80.3% in younger patients.
  • The 1-, 3-, and 5-year cancer-specific survival rates were 100.0%, 92.2%, and 83.6% in patients aged 75 years, and 98.6%, 92.6%, and 89.2% in younger patients.
  • The 1-, 3-, and 5-year recurrence-free survival rates were 82.1%, 60.6%, and 58.9% in patients aged 75 years, and 88.4%, 63.3%, and 61.6% in younger patients.
