Objective: Lung cancer remains the leading cause of malignant tumor-related death globally. There is mounting evidence that a large proportion of patients harboring epidermal growth factor receptor (EGFR) mutation and treated with EGFR TKI experience oligoprogressive disease. The optimal treatment strategy for these patients is undetermined. Thus, in this article, we report two cases of EGFR-mutant NSCLC patients with locally resistant lesions achieving disease control via combination therapy.
Patients and Methods: We present two cases of lung adenocarcinoma patients that developed oligoprogressive disease during TKI treatment. For further treatment, the patient then received radiofrequency ablation.
Results: Through follow-up observation, we found that the addition of radiofrequency ablation might provide the clinical benefit of these two NSCLC patients.
Conclusion: Our two cases provide a promising treatment for oligoprogressive disease during the first-line EGFR-TKI therapy.
