AIM: To better understand the hepatocellular carcinoma (HCC) patient journey, we conducted a patient survey across 13 countries. METHODS: The survey included closed- and open-ended questions developed using an iterative process to gather information on demographics, diagnosis and treatment. Patients self-selected or were directed to the online survey by their doctor. RESULTS: A total of 256 patients completed the survey. More than two-thirds (68%) felt they did not receive enough information about HCC at diagnosis...

Unresectableintrahepaticcholangiocarcinoma has a very poor prognosis despite various treatment options. The case presented describes the diagnostic challenges of a young pregnant woman with unresectable cholangiocarcinoma. The current treatment options for cholangiocarcinoma have limited evidence and high recurrence rate. Given the young age of this patient, selective internal radiotherapy was trialled with traditional chemotherapy with a clinically significant result. This case highlights the delays when diagnosing cholangiocarcinoma in younger patients and the possibility of selective internal radiation therapy in combination with chemotherapy as a potential first-line treatment for a complete response in unresectable disease...

Stereotactic radiosurgery (SRS) is frequently used for Cushing's disease (CD) after failed pituitary surgery. Management of patients with persistent CD after failed SRS is complex, as the alternative therapeutic options harbor significant risks. The outcomes of repeat pituitary radiosurgery, however, have not been described. We sought to determine the outcomes of repeat SRS in patients with CD. We pooled data from five institutions participating in the International Gamma Knife Research Foundation for patients with recurrent or persistent CD ≥ 12 months after initial SRS...

The presence of atmospheric brown carbon (BrC) has been the focus of many recent studies. These particles, predominantly emitted from biomass burning, absorb light in the near-ultraviolet wavelengths and offset the radiative cooling effects associated with organic aerosols. Particle density dictates their transport properties and is an important parameter in climate models and aerosol instrumentation algorithms, but our knowledge of this particle property is limited, especially as functions of combustion temperature and fuel type...

BACKGROUND: There is growing concern about radiation exposure from nuclear myocardial perfusion imaging (MPI), particularly among younger patients who are more prone to develop untoward effects of ionizing radiation, and hence US and European professional society guidelines recommend age as a consideration in weighing radiation risk from MPI. We aimed to determine how patient radiation doses from MPI vary across age groups in a large contemporary international cohort. METHODS: Data were collected as part of a global cross-sectional study of centers performing MPI coordinated by the International Atomic Energy Agency (IAEA)...

Non-invasive imaging techniques like X-ray computed tomography have become very popular in zoology, as they allow for simultaneous imaging of the internal and external morphology of organisms. Nevertheless, the effect of different staining approaches required for this method on samples lacking mineralized tissues, such as soft-bodied invertebrates, remains understudied. Herein, we used synchrotron radiation-based X-ray micro-computed tomography to compare the effects of commonly used contrasting approaches on onychophorans - soft-bodied invertebrates important for studying animal evolution...

We describe a 52-year-old female patient who presented with a 9.5-cm fibrolamellar hepatocellular carcinoma (FL-HCC). The patient was initially unsuitable for surgical resection and therefore underwent transarterial chemoembolization followed by selective internal radiation therapy (SIRT) with Yttrium-90 to downsize the tumour. Following SIRT, the tumour decreased in volume from 350 to 20 cm3 allowing curative (R0) resection with an extended left hepatectomy and reconstruction of IVC. This is the first reported case of FL-HCC treated with SIRT in which, due to the good SIRT response, the patient was downsized to allow curative resection...

Adrenocortical carcinoma (ACC) is a rare malignancy with generally poor outcomes and limited treatment options. While surgical resection can be curative for early local disease, most patients present with advanced ACC owing to nonspecific symptoms. For those patients, treatment options include systemic chemotherapy and locoregional therapies including radiofrequency ablation and transarterial chemoembolization. We present the first reported case of utilizing yttrium-90 microsphere selective internal radiation therapy (SIRT) in combination with first line EDP-M (Etoposide, Doxorubicin, Cisplatin, Mitotane) chemotherapy and debulking surgical primary tumor resection for treatment of metastatic ACC...

INTRODUCTION: Clinical Bremsstrahlung imaging with gamma cameras or SPECT scanners, for example used in selective internal radiation therapy (SIRT) [1], suffers from low contrast due to a continuous spectrum and a high amount of scatter. Information about the scattering of the radionuclide within the patient's body can be obtained from Monte-Carlo simulations and subsequently being used to improve image quality. METHODS: An MAA-acquisition (CT+SPECT) of a HCC patient with a unifocal uptake in the right liver lobe is segmented (lesion) and loaded into the MC simulation framework GATE [2]...
