A Study of Furmonertinib Combined With Radiotherapy for Non-small Cell Lung Cancer With Oligoprogression

This Phase II randomized study is to explore the efficacy and safety of Furmonertinib combined with radiotherapy for non-small cell lung cancer with oligoprogression after first-line EGFR-TKI therapy. The first group will enroll NSCLC patients with oligoprogression after using the first/second generation EGFR-TKI. The participants will receive Furmonertinib 80mg and local radiotherapy as the following therapy. The other group will enroll NSCLC patients with oligoprogression after using the third generation EGFR-TKI. The participants will receive Furmonertinib 160mg and local radiotherapy as the following therapy.
