Non-surgical Treatment of Metastatic Liver Tumors with Microwave Ablation.

With all the measures taken, the trend of liver cancer cases has increased worldwide, as a consequence, this is accompanied by an increase in mortality by 43% (10.3 per 100,000 in 2016 (USA)) [1, 2]. Liver cancer is also associated with the lowest 5-year survival rate among all types of cancer (19%) [1]. Liver cancer (including intrahepatic bile duct cancer) was the ninth leading cause of cancer death in 2000 and rose to sixth in 2016 [3]. This shows that the identification of safe and effective treatments for liver cancer is urgent now. Microwave ablation is a thermal ablation modality that has particular applicability in treating hepatic malignancies primary tumors or metastases. Microwaves can generate very high temperatures in short time periods, potentially leading to improved treatment efficiency in larger ablation zones. We will show a patient male 55 years old. Post-surgery of colon cancer 6 months ago. Normal exam. There is e liver metastasis in the right lobe subcapsular 22mm. The patient was a good candidate for MWA. Conclusions MWA is an effective and safe alternative in patients/tumors that are not suitable for resection. Survival and recurrence outcomes after MWA are significantly improved with significantly shorter hospital stays and operative times, with little or no intraoperative blood loss and minor complications. Its use should be extended more and more in the field of treatment of these patients depending on the therapeutic indications
