BACKGROUND Since 2005, we have treated hepatocellular carcinoma (HCC) with stereotactic body radiotherapy (SBRT) uniformly at two dose levels, according to baseline liver function and normal liver dose. We retrospectively examined the outcomes for these patients. MATERIAL AND METHODS Between 2005 and 2012, 221 HCC patients were treated with SBRT.(More)
PURPOSE Focal liver reaction (FLR) appears on radiographic images after stereotactic ablative body radiation therapy (SABR) in patients with hepatocellular carcinoma (HCC) and chronic liver disease. We investigated the threshold dose (TD) of FLR and possible factors affecting the TD on gadoxetate acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging (MRI).(More)
PURPOSE Stereotactic body radiotherapy (SBRT) is the standard care for medically inoperable early non-small-cell lung cancer (NSCLC). However, it can be difficult to differentiate local recurrence from non-recurrence radiation-induced lung opacity. We retrospectively assessed (18)F-FDG PET/CT to detect local recurrence after SBRT for NSCLC. METHODS(More)
BACKGROUND AND AIMS Stereotactic ablative body radiotherapy (SABR) is a relatively new treatment for hepatocellular carcinoma (HCC). The outcomes of SABR for previously untreated solitary HCC unfit for ablation and surgical resection were evaluated. METHODS Untreated solitary HCC patients treated with SABR were retrospectively studied. Between 2005 and(More)
OBJECTIVE The purpose of this study is to evaluate the CT appearances of tumor responses following hypofractionated stereotactic ablative body radiotherapy for small hypervascular hepatocellular carcinomas (HCCs) and to assess the relationship between tumor responses and local control. MATERIALS AND METHODS Among 277 HCC tumors treated with stereotactic(More)
BACKGROUND Evaluation of myocardial function is clinically challenging in dogs with degenerative mitral valve disease (DMVD). Although myocardial dysfunction is caused by pathologic degeneration, histopathologic progression is poorly understood. OBJECTIVES To characterize myocardial and pulmonary pathologic changes according to severity in dogs with(More)
To evaluate the outcomes and feasibility of stereotactic body radiotherapy (SBRT) for cT3 and cT4N0M0 non-small cell lung cancer (NSCLC), 25 patients with localized primary NSCLC diagnosed as cT3 or cT4N0M0, given SBRT between May 2005 and July 2013, were analyzed. All patients had inoperable tumors. The major reasons for tumors being unresectable were(More)
