Summary
Microwave ablation (MWA) is a safe and effective treatment for unresectable lung tumors in selected patients. This minimally invasive technique demonstrated technical success with no 30-day mortality, offering a viable alternative to other ablative methods.
Area of Science:
- Interventional Radiology
- Oncology
- Medical Physics
Background:
- Unresectable lung tumors pose a significant treatment challenge.
- Minimally invasive ablation techniques are increasingly explored for lung cancer palliation and treatment.
- Microwave ablation (MWA) offers a potential alternative to existing ablative modalities.
Purpose of the Study:
- To retrospectively evaluate the feasibility of microwave ablation (MWA) for unresectable lung tumors.
- To assess the safety and effectiveness of MWA in a cohort of patients with lung malignancies.
- To determine the procedural success rates and early outcomes of MWA in this patient group.
Main Methods:
- Ten unresectable lung lesions in nine patients were treated using MWA.
- Procedures utilized a 45 W, 915 MHz microwave generator and a 14.5-gauge antenna for 10-minute sessions.
- Antenna placement was guided by computed tomography (CT) fluoroscopy or XperGuide, with CT follow-up at 1, 3, and 6 months.
Main Results:
- Technical success was achieved in all treated lesions.
- No mortality was observed within 30 days post-procedure.
- All patients tolerated the MWA procedure well, indicating good feasibility.
Conclusions:
- Microwave ablation (MWA) is a feasible and safe treatment option for selected patients with unresectable lung tumors.
- MWA presents a valid alternative to other ablative techniques for lung malignancies.
- Further research is warranted to compare MWA with other ablation systems, particularly radiofrequency ablation, and to establish long-term efficacy.
