Microwave Ablation for Pulmonary Metastases From Colorectal Cancer

CT-guided Percutaneous Microwave Ablation for Pulmonary Metastases From Colorectal Cancer

(MWA) is the most recent development in the field of local ablative therapies. The aim of this study was to evaluate CT-guided percutaneous microwave (MW) ablation safety and efficacy in pulmonary metastases from colorectal cancer.

From June 2010 to June 2015, 48 unresectable lesions in 32 patients with pulmonary metastases from colorectal cancer were selected for CT-guided microwave ablation. Patients were scheduled for a 1 and 3 month CT follow-up to evaluate lesion diameter.We retrospectively evaluated CT-guided percutaneous microwave (MW) ablation safety and efficacy in pulmonary metastases from colorectal cancer.

Inclusion Criteria:

• Unresectable pulmonary metastases from colorectal cancer.
• diagnosis by CT, and confirmed by percutaneous puncture biopsy.
• Age range 18-70 years old.
• Eastern Cooperative Oncology Group performance status 0-1.
• Life expectancy of more than 3 months.
• Adequate organ function.

Exclusion Criteria:

• Resectable lung metastases.
• Life expectancy less than 3 months
• Patients with cardiac pacemaker, cerebral aneurysm clips, implanted electronic instruments or other metal materials.
• Coagulopathy with platelet count less than 50000.
• Active infectious disease.
• Age below 18 years.
• Pregnancy of breastfeeding.
