Clinical Efficacy and Safety of Microwave Ablation Combined With Huaier Granules in Patients With Inoperable Stage IA Non-Small Cell Lung Cancer: A Prospective, Single-Center, Randomized Controlled Clinical Trial

Patients in this arm will undergo CT-guided percutaneous microwave ablation using a standard protocol (2450 MHz, 30-50 W, 5-10 minutes per lesion, multi-probe as needed based on tumor size). Seven days post-ablation, patients will start oral administration of Huaier granules at a dose of 10g, three times daily (TID), for 72 consecutive weeks. The combined therapy aims to improve local tumor control and modulate anti-tumor immunity.
