BACKGROUND The objectives of this retrospective study was to evaluate the efficacy of stereotactic body radiation therapy (SBRT) for small non-resectable hepatocellular carcinoma (HCC) and SBRT combined with transarterial chemoembolization (TACE) for advanced HCC with portal vein tumor thrombosis (PVTT). METHODS Thirty one patients with HCC who were(More)
BACKGROUND We evaluated the long-term effect of stereotactic body radiation therapy (SBRT) for primary small hepatocellular carcinoma (HCC) ineligible for local therapy or surgery. METHODS Forty-two HCC patients with tumors ≤ 100 cc and ineligible for local ablation therapy or surgical resection were treated with SBRT: 30-39 Gy with a prescription isodose(More)
BACKGROUND The purpose of this study was to identify parameters capable of predicting the deterioration of hepatic function after helical tomotherapy in patients with unresectable locally advanced hepatocellular carcinoma. METHODS Between March 2006 and February 2012, 72 patients were eligible for this study. All patients received hypofractionated(More)
BACKGROUND The purpose of this study was to determine the α/β ratio for normal liver with hepatitis by analyzing the toxicity data from patients with unresectable hepatocellular carcinoma treated with helical tomotherapy. METHODS Between March 2006 and February 2012, 98 patients were eligible for this study. 66 patients received 45-50 Gy in 4.5-5 Gy(More)
PURPOSE To report the results of dosimetric comparison between intensity-modulated radiotherapy (IMRT) using Tomotherapy and four-box field conformal radiotherapy (CRT) for pelvic irradiation of locally advanced rectal cancer. MATERIALS AND METHODS Twelve patients with locally advanced rectal cancer who received a short course preoperative(More)
We evaluated 5-year follow-up of stereotactic body radiation therapy (SBRT) with Cyberknife for prostate cancer patients. Forty-five men with prostate adenocarcinoma who received SBRT using Cyberknife from May 2006 to November 2012 were enrolled in this study. They were prostate cancer patients with old age and medical comorbidities who received a total of(More)
BACKGROUND We attempted to analyze the effects of an increase in the Child-Pugh (CP) score on the overall survival of patients with unresectable hepatocellular carcinoma (HCC) after radiotherapy (RT). METHODS From March 2006 to February 2012, 103 patients received RT using the TomoTherapy Hi-Art at Incheon St. Mary's Hospital and Seoul St. Mary's(More)
PURPOSE Tomotherapy for intensity-modulated radiation has been demonstrated to reduce unnecessary irradiations to adjacent organs at risk (OARs). The purpose of this study was to compare the dosimetric parameters between Tomotherapy and three-dimensional conformal radiotherapy (3D-CRT) in rectal cancer patients. MATERIALS AND METHODS We redesigned(More)
PURPOSE This single institutional study is aimed to observe the outcome of patients who received postoperative radiotherapy after radical prostatectomy. MATERIALS AND METHODS A total of 59 men with histologically identified prostate adenocarcinoma who had received postoperative radiation after radical prostatectomy from August 2005 to July 2011 in Seoul(More)
To evaluate the efficacy and toxicity for patients with hepatic oligometastases, receiving hypofractionated radiotherapy with Tomotherapy to the liver. A total of 42 patients with 54 hepatic lesions, who had been treated from 2007 to 2011 at two institutions, were retrospectively reviewed for this study. All the patients received radical resections of the(More)
