PURPOSE: To investigate the degree and effect of cyclooxygenase (COX)-2 expression on the survival of patients with glioblastoma multiforme (GM). MATERIALS AND METHODS: Between 1997 and 2006, thirty consecutive GM patients treated with surgery and postoperative radiotherapy (dose range: 44~65.1 Gy, median dose: 61.2 Gy) were included in the study. Three patients were excluded that discontinued radiotherapy before receiving a dose...

PURPOSE: The purpose of this study is to present the treatment results and to identify possible prognostic indicators in patients with locally advanced hypopharyngeal carcinoma. MATERIALS AND METHODS: Between October 1985 to December 2000, 90 patients who had locally advanced stage IV hypopharyngeal carcinoma were studied retrospectively. Twelve patients were treated with radiotherapy alone, 65 patients were treated with a combination of...

PURPOSE: This study reports the results of the use of preoperative concurrent radiochemotherapy (CRCT) for the treatment of locoregionally advanced esophageal cancer. MATERIALS AND METHODS: From 1998 through 2005, 61 patients with intrathoracic esophageal cancer at stages II-IVB (without distant organ metastasis and presumed to be respectable) received preoperative CRCT. CRCT consisted of radiotherapy (45 Gy /25 fractions /5 weeks) and...

PURPOSE: To determine the role of radiotherapy for the treatment of portal vein thrombosis (PVT) from hepatocellular carcinoma (HCC). MATERIAL AND METHODS: A retrospective analysis was performed on 70 patients that had been diagnosed with HCC and were treated with three-dimensional conformal radiotherapy (3D-CRT) for the PVT. The radiation dose ranged from 40 Gy to 60 Gy (median dose: 48 Gy)...

PURPOSE: To evaluate the palliative effect of endobronchial brachytherapy (EBB) for patients with lung cancer that previously received external beam radiotherapy (EBRT). MATERIALS AND METHODS: From July 1992 to May 2003, 29 patients with a recurrent or persistent lung cancer were treated with palliative EBB at our institute. EBB consisted of three fractions (once a week) of a dose of 5...

PURPOSE: This study was performed to investigate the effects of immune cell activation and the antitumor effect for the combination of treatment with X-irradiation and Eleutherococcus senticosus Maxim Root (ESMR) on mouse tumor cells. MATERIALS AND METHODS: ESMR (250g) was extracted with 80% methanol, concentrated under decompression and lyophilized. To determine whether ESMR is able to activate the immune cells or not,...
