INTRODUCTION In recent years, various types of medical applications of microwaves have widely been investigated and reported [1]. In particular, minimally invasive microwave thermal therapies using thin applicators are of a great interest. They are interstitial microwave hyperthermia [2] and microwave coagulation therapy (MCT) [3] for medical treatment of cancer, cardiac catheter ablation for v...

There is a lack of studies that examine the dynamics of heat-induced shrinkage of organ tissues. Clinical procedures such as radiofrequency ablation, microwave ablation or high-intensity focused ultrasound, use heat to treat diseases such as cancer and cardiac arrhythmia. When heat is applied to tissues, shrinkage occurs due to protein denaturation, dehydration and contraction of collagen at te...

Microwave endometrial ablation (MEA) is effective for the emergency control of uterine hemorrhage. However, to the best of our knowledge, there has been only a single report of life-threatening hemorrhage induced by endometrial carcinoma that was treated with MEA. The present report evaluates the efficacy of MEA as an emergency therapeutic option for the control of bleeding due to advanced endo...

Early detection of metastatic disease within the liver by advanced diagnostic imaging has driven the rise of image-guided intervention for hepatic metastases. In this talk, we will explore the rationale, indications, technique and post procedure imaging findings of percutaneous treatments of liver metastases. Curative intent ablative therapies, such as radiofrequency ablation, microwave ablatio...

PURPOSE To identify changes in plasma cytokine levels after image-guided thermal ablation of human tumors and to identify the factors that independently predict changes in plasma cytokine levels. MATERIALS AND METHODS Whole-blood samples were collected from 36 patients at three time points: before ablation, after ablation (within 48 hours), and at follow-up (1-5 weeks after ablation). Plasma ...

A preponderance of patients with neuroendocrine tumors (NETs) will experience hepatic metastases during the course of their disease. Many diagnoses of NETs are made only after the neoplasms have spread from their primary gastroenteropancreatic sites to the liver. This paper reviews current evidence-based treatments for neuroendocrine hepatic metastases, encompassing surgery, hepatic artery embo...

BACKGROUND Hepatocellular carcinoma (HCC) remains a major health issue because of its increasing incidence and because of the complexity of its management. In addition to the traditional potentially curative treatments, i.e., liver transplantation and surgical resection, other new and emerging local therapies have been applied with promising results. SUMMARY Radiotherapy (RT) and interstitial...

BACKGROUND An axisymmetric finite element method (FEM) model was employed to demonstrate important techniques used in the design of antennas for hepatic microwave ablation (MWA). To effectively treat deep-seated hepatic tumors, these antennas should produce a highly localized specific absorption rate (SAR) pattern and be efficient radiators at approved generator frequencies. METHODS AND RESUL...
