The goal of this Single-arm, Phase II clinical trial is to learn whether ablation or stereotactic radiotherapy combined with furmonertinib can treat early-stage non-small cell lung cancer in patients who are inoperable or refuse surgery. The main purposes of this study is to answer: Can ablation or stereotactic radiotherapy combined with furmonertinib improve survival in patients with early-stage NSCLC who are inoperable or refuse surgery? Can ablation or stereotactic radiotherapy combined with furmonertinib reduce recurrence in patients with early-stage NSCLC who are inoperable or refuse surgery?

furmonertinib 80 mg once daily (QD), administered orally for 3 consecutive years
1. Immobilization and image guidance: Supine or prone position; vacuum cushion or mask to limit motion. CT guidance for entry point, angle, and depth; ultrasound for selected peripheral lesions. 2. Ablation target planning: Ablation zone should cover GTV with ≥5-10 mm margin. For tumors near critical structures, pursue adequate margin when safe; consider heat sink or thermal isolation. 3. Ablation procedure: Choose MWA, RFA, or cryoablation based on tumor size, location, anatomy, and resources. 4. Intraprocedural monitoring and endpoint assessment: CT during/after ablation to confirm ground-glass opacity covers tumor with planned margin. Ablation zone ≥5 mm beyond tumor = technical success. If inadequate, reposition and supplement. 5. Post-procedure management and follow-up: Monitor vital signs; manage complications as needed.
1. Immobilization: Use a thermoplastic mask or vacuum cushion for immobilization based on the treatment site. 2. CT simulation: After immobilization and stabilization of breathing, laser alignment is performed, followed by 4D-CT simulation (preferred) or conventional CT simulation. 3. Radiotherapy target delineation and dose: GTV includes the primary lung tumor and metastatic lymph nodes after chemotherapy. A 5-mm margin is added to form the PTV. 4. Radiotherapy plan: For peripheral lesions: 48 Gy in 4 fractions or 50 Gy in 5 fractions; for central lesions: 60 Gy in 8 fractions or 60 Gy in 10 fractions.

2-year EFS rate
defined as the proportion of patients who experience no event (including disease progression, recurrence, distant metastasis, discontinuation of treatment for any reason, or death) within 24 months from the start of treatment, relative to the total enrolled population.
Time frame: Within two years after the treatment
3-year EFS rate
defined as the proportion of patients who experience no event (including disease progression, recurrence, distant metastasis, or death) within 36 months from the start of treatment, relative to the total enrolled population.
Time frame: Within three years after the treatment
overall survival
defined as the time from the start of treatment to death from any cause
Time frame: through study completion, an average of 5 year
Local control rate (LCR)
defined as the proportion of patients who show no radiographic enlargement or recurrence of the primary tumor during follow-up
Time frame: through study completion, an average of 1 year
Time to distant metastasis
defined as the time from the start of treatment to the first occurrence of distant metastasis (e.g., to bone, brain, liver, or distant lymph nodes)
Time frame: through study completion, an average of 1 year
