BACKGROUND Recent studies using stereotactic body radiotherapy (SBRT) for hepatocellular carcinoma (HCC) have reported high tumor response and local control. However, the optimal SBRT dose remains unknown, and it is still not clear whether a dose response relationship for local control (LC) and overall survival (OS) exist or not. We performed this study to(More)
BACKGROUND The objective of this study was to evaluate the efficacy and safety of stereotactic body radiation therapy (SBRT) as a local salvage treatment after incomplete transarterial chemoembolization (TACE) for inoperable hepatocellular carcinoma (HCC). METHODS The main eligibility criteria were a greatest tumor dimension (LD sum) <10 cm, inoperable(More)
BACKGROUND AND OBJECTIVES This study evaluated the treatment result of high dose stereotactic body radiation therapy (SBRT) for colorectal oligometastases. METHODS Between 2003 and 2009, 41 patients with 50 lesions confined to one organ from colorectal cancer (CRC) and treated with high dose SBRT ≥45 Gy were retrospectively reviewed. Lymph nodes (LNs) (18(More)
PURPOSE To determine the effectiveness of salvage radiation therapy (RT) in patients with loco-regional recurrences (LRR) following initial complete resection of non-small cell lung cancer (NSCLC) and assess prognostic factors affecting survivals. MATERIALS AND METHODS Between 1994 and 2007, 64 patients with LRR after surgery of NSCLC were treated with(More)
PURPOSE The purpose of this study is to investigate the current status of stereotactic body radiotherapy (SBRT) in Korea. A nationwide survey was conducted by the Korean Stereotactic Radiosurgery Group of the Korean Society for Radiation Oncology (KROG 13-13). MATERIALS AND METHODS SBRT was defined as radiotherapy with delivery of a high dose of radiation(More)
PURPOSE To identify the predictors for the development of severe gastroduodenal toxicity (GDT) in patients treated with stereotactic body radiotherapy (SBRT) using 3 fractionations for abdominopelvic malignancies. METHODS AND MATERIALS From 2001 to 2011, 202 patients with abdominopelvic malignancies were treated with curative-intent SBRT. Among these(More)
BACKGROUND To evaluate the palliative role of radiotherapy (RT) and define the effectiveness of chemotherapy combined with palliative RT (CCRT) in patients with a symptomatic pelvic mass of metastatic colorectal cancer. METHODS From August 1995 to December 2007, 80 patients with a symptomatic pelvic mass of metastatic colorectal cancer were treated with(More)
The purpose of this study is to identify the predictors for severe intestinal toxicity (IT) in patients with abdominopelvic malignancies treated with three fractions of stereotactic ablative radiotherapy (SABR). From 2001 to 2011, 202 patients with abdominopelvic malignancies were treated with curative-intent SABR. Among these, we retrospectively reviewed(More)
PURPOSE To evaluate and compare the risks of secondary cancers from therapeutic doses received by patients with hepatocellular carcinoma (HCC) during intensity-modulated radiotherapy (IMRT), volumetric arc therapy (VMAT), and tomotherapy (TOMO). METHODS Treatments for five patients with hepatocellular carcinoma (HCC) were planned using IMRT, VMAT, and(More)
PURPOSE To investigate the rates of tumor response and local control in patients with recurrent small hepatocellular carcinoma (HCC) treated with hypofractionated radiotherapy (RT) as a salvage treatment and to evaluate treatment-related toxicities. METHODS AND MATERIALS Between 2006 and 2009, a total of 20 patients with recurrent small HCC were treated(More)
