JOURNAL OF VASCULAR AND INTERVENTIONAL RADIOLOGY. Localized Hyperthermia with Iron Oxide–Doped Yttrium Microparticles: Steps toward Image-Guided Thermoradiotherapy in Liver Cancer

Andrew C. Gordon, BA , Robert J. Lewandowski, MD , Riad Salem, MD, MBA , Delbert E. Day, PhD, MS , Reed A. Omary, MD, MS , Andrew C. Larson, PhD

Purpose: To test whether iron oxide (IO)–containing yttrium aluminosilicate (YAS) microparticles (MPs) can generate localized therapeutic hyperthermia (≥ 43°C) when injected intratumorally in an animal model of liver cancer and whether MP distributions could be visualized with magnetic resonance (MR) imaging.

WORLD JOURNAL OF GASTROENTEROLOGY. Bridging and downstaging treatments for hepatocellular carcinoma in patients on the waiting list for liver transplantation

Maurizio Pompili, Giampiero Francica, Francesca Romana Ponziani, Roberto Iezzi and Alfonso Wolfango Avolio.

Several therapeutic procedures have been proposed as bridging treatments for patients with hepatocellular carcinoma (HCC) awaiting liver transplantation (LT). The most used treatments include transarterial chemoembolization and radiofrequency ablation. Surgical resection has also been successfully used as a bridging procedure, and LT should be considered a rescue treatment in patients with previous HCC resection who experience tumor recurrence or post-treatment severe decompensation of liver function. The aims of bridging treatments include decreasing the waiting list dropout rate before transplantation, reducing HCC recurrence after transplantation, and improving post-transplant overall survival. To date, no data from prospective randomized studies are available; however, for HCC patients listed for LT within the Milan criteria, prolonging the waiting time over 6-12 mo is a risk factor for tumor spread. Bridging treatments are useful in containing tumor progression and decreasing dropout. Furthermore, the response to pre-LT treatments may represent a surrogate marker of tumor biological aggressiveness and could therefore be evaluated to prioritize HCC candidates for LT. Lastly, although a definitive conclusion can not be reached, the experiences reported to date suggest a positive impact of these treatments on both tumor recurrence and post-transplant patient survival. Advanced HCC may be downstaged to achieve and maintain the current conventional criteria for inclusion in the waiting list for LT. Recent studies have demonstrated that successfully downstaged patients can achieve a 5-year survival rate comparable to that of patients meeting the conventional criteria without requiring downstaging.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Root Cause Analysis of Gastroduodenal Ulceration After Yttrium-90 Radioembolization

Marnix G. E. H. Lam, Subhas Banerjee, John D. Louie, Mohamed H. K. Abdelmaksoud, Andrei H. Iagaru, Rebecca E. Ennen, Daniel Y. Sze

Introduction: A root cause analysis was performed on the occurrence of gastroduodenal ulceration after hepatic radioembolization (RE). We aimed to identify the risk factors in the treated population and to determine the specific mechanism of nontarget RE in individual cases.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Selective Internal Radiotherapy (SIRT) of Hepatic Tumors: How to Deal with the Cystic Artery

Jens M. Theysohn, Stefan Müller, Jörg F. Schlaak, Judith Ertle, Thomas W. Schlosser, Andreas Bockisch, Thomas C. Lauenstein

Purpose: Selective internal radiotherapy (SIRT) with the beta emitter yttrium-90 (Y90) is a rapidly developing therapy option for unresectable liver malignancies. Nontarget irradiation of the gallbladder is a complication of SIRT. Thus, we aimed to assess different strategies to avoid infusion of Y90 into the cystic artery (CA).

THE SAUDI JOURNAL OF GASTROENTEROLOGY. Intra-arterial CT angiography visualization of arterial supply to inferior vena cava tumor thrombus prior to radioembolization of hepatocellular carcinoma

Glen Roche, Terence K. B. Teo, Andrew E. H. Tan, Farah G Irani

Unresectable hepatocellular carcinoma has a high frequency of vascular invasion and arterial parasitization. Trans-arterial radioembolization using yttrium-90 (Y90) microspheres is a possible treatment option. Paramount to its success is the meticulous angiographic interrogation of tumor feeding arteries and extra-hepatic supply. We describe a patient with tumor invasion of the inferior vena cava with arterial supply from the right inferior phrenic artery, which was exquisitely visualized using intra-arterial computed tomographic angiography (IACTA) during the planning technetium-99m macro aggregated albumin phase. This technique was useful in planning which artery to administer Y90 microspheres into for maximal brachytherapy. Although patient outcome was poor due to significant arterio-portal shunting, we believe that IACTA is a useful adjunct to conventional digital subtraction angiography in planning radioembolization therapy.
