In this work, a novel magnetic resonance (MR)-compatible microwave antenna was designed and validated in a small animal superficial hyperthermia applicator. The antenna operates at 2.45 GHz and matching is made robust against production and setup inaccuracies. To validate our theoretical concept, a prototype of the applicator was manufactured and tested for its properties concerning input reflection, sensitivity for setup inaccuracies, environment temperature stability and MR-compatibility. The experiments show that the applicator indeed fulfills the requirements for MR-guided hyperthermia investigation in small animals: it creates a small heating focus (< 1 cm(3)), has a stable and reliable performance (S11 < -15 dB) for all working conditions and is MR-compatible...

BACKGROUND: Temperature increase in tumor tissue during photothermal therapy (PTT) is a significant factor in determining the outcomes of the treatment. Therefore, controlling and optimizing temperature distribution in target tissue is crucial for PTT. In this study, we developed a unique ex vivo device to study the temperature distribution during PTT to be used as a guide for the desired photothermal effects for cancer treatment. METHODS: Bovine liver tissue buried inside agarose gel served as a phantom tumor surrounded by normal tissue...

Papillary thyroid carcinoma (PTC) is the most common subtype of thyroid malignancy and has a good prognosis and low mortality rate. Surgery is the standard treatment for patients with primary and recurrent thyroid cancer. Although patients with PTC usually exhibit excellent treatment outcome, the incidence of recurrence in the neck ranges from 20% to 59%. When a patient with thyroid cancer is contraindicated for surgery, ultrasound (US)-guided ablation techniques, including ethanol ablation (EA) and thermal ablations, are suggested alternatives...

Brian H H Lang, Yu Cho Woo, Keith W H Chiu
BACKGROUND: Given that high-intensity focussed ultrasound (HIFU) of benign thyroid nodules often causes a massive release of thyroglobulin (Tg) into the circulation, we hypothesised a greater initial Tg rise may result in a greater nodule shrinkage 6 months after ablation. METHODS: One hundred and five patients who underwent HIFU for symptomatic benign thyroid nodule from 2015 to 2016 were analysed. Serum Tg and anti-Tg autoantibody were checked on treatment day (baseline) and 4 d after treatment...

BACKGROUND: Microwave ablation (MWA) is an effective treatment for severe secondary hyperparathyroidism (SHPT), but it can also be used for mild-to-moderate secondary hyperparathyroidism (SHPT). In this randomised, controlled study, the efficacy of MWA in the treatment of mild-to-moderate hyperparathyroidism is investigated. MATERIALS AND METHODS: We assessed outcomes 12 months after the randomisation of 28 patients with mild-to-moderate SHPT. The subjects received either MWA plus calcitriol or calcitriol alone...

We report the development and optimisation of an assay for quantitating iron from iron oxide nanoparticles in biological matrices by using ferene-s, a chromogenic compound. The method is accurate, reliable and can be performed with basic equipment common to many laboratories making it convenient and inexpensive. The assay we have developed is suited for quantitation of iron in cell culture studies with iron oxide nanoparticles, which tend to manifest low levels of iron. The assay was validated with standard reference materials and with inductively coupled plasma-mass spectrometry (ICP-MS) to accurately measure iron concentrations ∼1 × 10(-6) g in about 1 × 10(6) cells (∼1 × 10(-12) g Fe per cell)...

AIM: Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is routinely used to treat selected patients with peritoneal carcinomatosis, but can be associated with prolonged hospital stay, significant morbidity and mortality. Our objective was to assess whether patients undergoing gastrectomy as part of CRS/HIPEC were at increased risk of delayed feeding time and prolonged hospital stay. METHODS: Two hundred and fourteen consecutive patients with peritoneal carcinomatosis treated with CRS/HIPEC between 2001 and 2016 were stratified by whether CRS included gastrectomy (n = 19, 9%) and compared...

OBJECTIVES: This study investigated the correlation between the peritoneal carcinomatosis index (PCI) and patient outcome depending on the tumour type. BACKGROUND: Peritoneal surface malignancy (PSM) treatment depends on tumour type. Mucinous PSM (m-PSM) is associated with a better prognosis than non-mucinous PSM (nm-PSM). The PCI's predictive ability has not yet been evaluated. METHODS: We analysed 123 patients with PSM treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) between 2008 and 2015...

INTRODUCTION: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have been found to prolong survival in patients with peritoneal disease but is associated with significant morbidity. We evaluate the perioperative complications and the association with the chemotherapy agent used for HIPEC. METHODS: Retrospective analysis of a prospectively collected database of CRS-HIPEC cases between April 2001 and February 2016 was performed. Patients were stratified by the chemotherapy used, and perioperative complications were compared...
