What is Microwave Ablation for Lung Tumors?

CT-guided percutaneous microwave ablation destroys lung tumors using thermal energy delivered through a thin antenna inserted directly into the tumor. It offers a curative-intent alternative to surgery for early-stage NSCLC patients who cannot tolerate resection.

Why China?

• Pioneered technique: Chinese interventional radiologists developed key MWA protocols for lung
• Cost: $4,500-$7,500 vs. $20,000-$40,000 in the US
• Same-day discharge: No general anesthesia, minimal recovery
• Repeatable: Can re-treat new lesions or local recurrence

Who is a candidate?

• Stage I NSCLC ≤3cm in patients medically unfit for surgery
• Pulmonary metastases (≤3 lesions, ≤3cm each)
• Failed prior radiation

Outcomes

Local control: 80-90% for tumors <3cm. 3-year overall survival for stage I: 60-70%. Pneumothorax rate: 20-30% (most resolve with chest tube).
