Efficacy and safety of sorafenib plus vitamin K treatment for hepatocellular carcinoma: A phase II, randomized study.

The previous retrospective study suggested that dosing vitamin K may enhance the anticancer action of sorafenib against hepatocellular carcinoma. To confirm it, we performed a phase II, randomized, open-label study. Patients with hepatocellular carcinoma were randomly assigned to receive sorafenib + vitamin K2 (menatetrenone, 45 mg daily, orally) or sorafenib only.

Clinical Impact of Vitamin K Dosing on Sorafenib Treatment for Hepatocellular Carcinoma.

Some researchers have suggested that vitamin K enhances the antitumor effect of sorafenib for hepatocellular carcinoma (HCC) in vitro and in vivo. In this study, we examined the clinical impact of vitamin K dosing for sorafenib treatment. Twenty-nine out of 65 patients treated with sorafenib for HCC were simultaneously dosed with vitamin K.

Therapeutic sclerosis of a small liver cyst that caused obstructive jaundice.

The authors describe the case of a small liver cyst (2 cm in diameter) causing obstructive jaundice that was treated with aspiration and therapeutic sclerosis. The procedure was performed with use of a microcatheter and wire system to access the cyst, which was injected with minocycline hydrochloride. At present, 9 months after treatment, the levels of hepatobiliary enzymes are within normal ranges, and no sign of cyst regrowth has been detected on imaging.

[Case of giant renal arteriovenous fistula in a long-term hemodialysis patient].

We report a case of giant left renal arteriovenous fistula (AVF). A 36-year-old man was diagnosed with chronic glomerulonephritis (CGN) by biopsy on the left kidney 11 years ago. He had been receiving hemodialysis for end-stage kidney disease from CGN since 10 years ago.

Application of pixel truncation to reduce intensity artifacts in myocardial SPECT imaging with Tc-99m tetrofosmin.

Background: Technetium 99m-labeled radiopharmaceuticals accumulate in the liver and gallbladder, where they generate intensity artifacts that can result in misdiagnosis of myocardial single photon emission computed tomography (SPECT) images. This study identifies and eliminates factors affecting the magnitude and appearance of intensity artifacts in a gallbladder-heart phantom.

Methods And Results: The myocardium and background compartments of a phantom were filled with Tc-99m at concentrations of 320 and 26.
