Single administration of Selective Internal Radiation Therapy versus continuous treatment with sorafeNIB in locally advanced hepatocellular carcinoma (SIRveNIB): study protocol for a phase iii randomized controlled trial.

Background: Approximately 20 % of hepatocellular carcinoma (HCC) patients diagnosed in the early stages may benefit from potentially curative ablative therapies such as surgical resection, transplantation or radiofrequency ablation. For patients not eligible for such options, prognosis is poor. Sorafenib and Selective Internal Radiation Therapy (SIRT) are clinically proven treatment options in patients with unresectable HCC, and this study aims to assess overall survival following either SIRT or Sorafenib therapy for locally advanced HCC patients.

Survival and pattern of tumor progression with yttrium-90 microsphere radioembolization in predominantly hepatitis B Asian patients with hepatocellular carcinoma.

Purpose: Intra-arterial yttrium-90 ((90)Y) microsphere radioembolization (RE) is an emerging treatment option with good outcomes reported predominantly in hepatitis C Western populations with hepatocellular carcinoma (HCC). We report outcomes in predominantly hepatitis B Asian patients treated with (90)Y-RE focusing on overall survival (OS), time to progression (TTP), tumor response, pattern of tumor recurrence and adverse events. Prognostic factors for survival were also identified.

Underlying liver disease influences volumetric changes in the spared hemiliver after selective internal radiation therapy with 90Y in patients with hepatocellular carcinoma.

Objective: Hypertrophy of the contralateral liver lobe after treatment with yttrium-90 ((90)Y) microspheres has recently been reported. This study aimed to quantify left hepatic lobe hypertrophy after right-sided radioembolization for hepatocellular carcinoma (HCC) and to identify pretreatment predictive factors of hypertrophy in an Asian population.

Methods: A retrospective review of patients with inoperable HCC undergoing selective internal radiation treatment (SIRT) with (90)Y microspheres at a single institution from January 2008 to January 2012 was performed.

Radioembolization with infusion of yttrium-90 microspheres into a right inferior phrenic artery with hepatic tumor supply is feasible and safe.

Purpose: To evaluate the feasibility and safety of yttrium-90 ((90)Y) radioembolization through the inferior phrenic arteries (IPAs).

Materials And Methods: Retrospective analysis of 108 patients referred for radioembolization to treat primary (n = 103) or secondary (n = 5) liver malignancy was performed. Five patients had malignant hepatic tumors supplied by the IPA and met criteria for infusion of (90)Y spheres into the IPA.

Image-guided personalized predictive dosimetry by artery-specific SPECT/CT partition modeling for safe and effective 90Y radioembolization.

Unlabelled: Compliance with radiobiologic principles of radionuclide internal dosimetry is fundamental to the success of (90)Y radioembolization. The artery-specific SPECT/CT partition model is an image-guided personalized predictive dosimetric technique developed by our institution, integrating catheter-directed CT hepatic angiography (CTHA), (99m)Tc-macroaggregated albumin SPECT/CT, and partition modeling for unified dosimetry. Catheter-directed CTHA accurately delineates planning target volumes.

A novel approach to brachytherapy in hepatocellular carcinoma using a phosphorous32 (32P) brachytherapy delivery device--a first-in-man study.

Purpose: While potentially very useful, percutaneously delivered brachytherapy of inoperable intra-abdominal solid tumors faces significant technical challenges. This first-in-man study is designed to determine the safety profile and therapeutic efficacy of a novel phosphorous (32P) brachytherapy device (BrachySil) in patients with unresectable hepatocellular carcinoma.

Methods And Materials: Patients received single percutaneous and transperitoneal implantations of BrachySil under local anesthesia directly into liver tumors under ultrasound or computed tomographic guidance, at an activity level of 4 MBq/cc of tumor.
