PURPOSE: We aimed to compare the clinical effectiveness of combination therapy of transarterial chemoembolization (TACE) and microwave ablation (MWA) with TACE monotherapy in BCLC stage B HCC patients with tumor size ≤7 cm and tumor number ≤5. METHODS: We retrospectively reviewed 150 BCLC stage B HCC patients who had received TACE monotherapy or TACE-MWA combination therapy in our hospital from March 2007 to April 2016. The patients were matched by propensity score at the ratio of 1:2 by optimal method...

INTRODUCTION: This study aimed to evaluate the cognitive performance of migraine patients with (MwA) and without aura (MwoA) and investigate the correlation of white matter hyperintensities (WMHs) and psychological symptoms with their cognitive test scores. MATERIAL AND METHODS: Hundred migraine patients aged 20-55 years and 80 healthy volunteers with similar age, sex, and education level were enrolled. The total Montreal Cognitive Assessment (MoCA) scores were compared by age, sex, presence of aura, migraine duration, attack frequency, pain localization, presence and number of WMHs, and the scores of the Beck Depression Inventory and the Beck Anxiety Inventory (BAI)...

Background: In oncologic field, thermo-ablative procedures have spread more and more. Percutaneous microwave ablation (MWA) showed same benefits and some advantages over radiofrequency ablation (RFA). To date, a disadvantage of both was the not totally predictable size and shape of ablation volume. The aim of this study was to assess feasibility and safety of MWA in nonresectable pancreatic head cancer using a new technology of MW with high power (100 W) and frequency of 2,450 MH. Methods: Five patients with pancreatic head cancer treated with percutaneous MWA under ultrasound guidance were retrospectively reviewed...

PURPOSE: The present study compared the safety and efficacy of oxycodone with those of fentanyl under non-intubated general anaesthesia in percutaneous microwave ablation (MWA) of a liver tumour abutting the capsule. MATERIALS AND METHODS: Thirty-eight patients underwent MWA of liver cancers abutting the capsule. Patients received 0.1 mg/kg oxycodone (O group) or 1 μg/kg fentanyl (F group) prior to the start of ablation. Both groups received continuous infusions of propofol for non-intubated general anaesthesia during ablation...

PURPOSE:  Local ablative therapies have become an established treatment option in interventional oncology. Radiofrequency ablation (RFA) and microwave ablation (MWA) are a standard of care in the treatment of hepatocellular carcinoma (HCC). Currently, there is an increasing interest in cryotherapy, one of the oldest ablation techniques. It has some unique characteristics with regard to technology and mechanism of action. MATERIALS AND METHODS:  A systematic literature search using the terms cryotherapy, cryosurgery and cryoablation was performed...

OBJECTIVE: We reviewed nationwide follow-up data to determine outcomes of different treatments for early-stage hepatocellular carcinoma (HCC) in elderly patients. SUMMARY BACKGROUND DATA: Outcomes of early-stage HCC treatments in elderly patients have not been prospectively compared. METHODS: We included 6490 HCC patients, aged ≥75 years at treatment, who underwent curative hepatic resection (HR, n = 2020), radiofrequency ablation (RFA, n = 1888), microwave ablation (MWA, n = 193), or transcatheter arterial chemoembolization (TACE, n = 2389), and compared their characteristics and survival...

Migraineurs with aura (MWA) express higher inter-ictal response to non-noxious and noxious experimental sensory stimuli compared to migraineurs without aura (MWoA), but whether these differences also prevail in response to everyday non-noxious stimuli is not yet explored. This is a cross-sectional study testing fifty-three female migraineurs (30 MWA; 23 MWoA) that underwent wide battery of noxious psychophysical testing at pain-free phase, and completed a sensory responsiveness questionnaire and pain-related psychological questionnaires...

OBJECTIVE: Benign thyroid nodules occur commonly but only require treatment when symptomatic. Surgical treatment, once routine, has been replaced by newer technologies, such as microwave ablation (MWA). The aim of this study was to assess the efficacy, tolerability, and cost of MWA compared to surgery to treat benign thyroid nodules. METHODS: After obtaining ethical approval and informed consent, a prospective trial was conducted with 52 patients who had symptomatic benign thyroid nodules...

Dopant-segregated source/drain contacts in a p-channel Schottky-barrier metal-oxide semiconductor field-effect transistor (SB-MOSFET) require further hole Schottky barrier height (SBH) regulation toward sub-0.1 eV levels to improve their competitiveness with conventional field-effect transistors. Because of the solubility limits of dopants in silicon, the requirements for effective hole SBH reduction with dopant segregation cannot be satisfied using mono-implantation. In this study, we demonstrate a potential solution for further SBH tuning by implementing the dual implantation of boron (B) and aluminum (Al) in combination with microwave annealing (MWA)...

REVIEW
Sunyoung Lee, Matthew Loecher, Renuka Iyer
Hepatocellular carcinoma (HCC) is the fastest growing malignancy in the United States in relation to mortality. HCC relies on a complex immunosuppressive network to modify the host immune system and evade destruction. Intrinsic to the liver's function and anatomy, native hepatic and immune cells produce many inhibitory cytokines that promote tolerogenicity and limit immune response. Since the introduction of sorafenib in 2008, no treatment has been able to demonstrate improved survival in patients with advanced HCC post disease progression treated with sorafenib...

Objective: The objective of this study is to determine whether structural features of the vertebrobasilar arterial system are related to migraine. Background: Alterations in cerebral vascular structure and function have been associated with migraine, possibly mediated by hypoperfusion and/or endothelial dysfunction triggering cortical spreading depression. Vessel tortuosity, in particular, has been associated with both altered hemodynamics and endothelial function...

Thermal ablation is an alternative treatment for colorectal cancer liver metastasis (CRLM). However, prognostic factors in patients with CRLM who have undergone microwave ablation (MWA) have not been clearly defined. Therefore, this study aimed to analyze the risk factors associated with early recurrence in patients with CRLM treated with MWA.Herein, we retrospectively analyzed data for 140 patients with CRLM who underwent MWA from 2013 to 2015 in our institution. Patients were grouped by median pretreatment carcinoembryonic antigen (CEA) level into the high CEA level (>3...
