|
PURPOSE: Oligodendrogliomas (ODG) are a rare, slow growing, tumor in the brain, which can be cured by complete surgical resection, but as yet it is not known if postoperative adjuvant radiation therapy (RT) is essential. We analyzed the treatment results of patients with irradiated ODG to investigate the efficacy of RT in terms of survival rates and other influencing prognostic... |

-
|
PURPOSE: To evaluate the role of postoperative chemoradiotherapy in locally advanced rectal cancer, we retrospectively analyzed the treatment results of patients treated by curative surgical resection and postoperative chemoradiotherapy.
MATERIALS AND METHODS: From April 1989 through December 1998, 119 patients were treated with curative surgery and postoperative chemoradiotherapy for rectal carcinoma in Gyeongsang National University Hospital. Patient age ranged from 32... |

- High-Dose-Rate Brachytherapy for Uterine Cervical Cancer : The Results of Different Fractionation Regimen
- Won Sup Yoon, Tae Hyun Kim, Dae Sik Yang, Myung Sun Choi, Chul Yong Kim
-
Radiat Oncol J. 2002;20(3):228-236.
-
|
PURPOSE: Although high-dose-rate (HDR) brachytherapy regimens have been practiced with a variety of modalities and various degrees of success, few studies on the subject have been conducted. The purpose of this study was to compare the results of local control and late complication rate according to different HDR brachytherapy fractionation regimens in uterine cervical cancer patients.
METHODS AND MATERIALS: From November... |

Radiat Oncol J. 2002;20(3):246-252.
-
|
PURPOSE: It has been recognized that interaction of the Fas : Fas ligand plays an important role in radiation-induced apoptosis. The purpose of this study was to investigate the role of Fas mutation in radiation-induced apoptosis in vivo.
MATERIALS AND METHODS: Mice with mutations in Fas, MRL/Mpj-Fas(lpr), and its normal control, MRL/Mpj, were used in this study. Eight-week old male... |

|
PURPOSE: Three-dimensional radiation dosimetry using magnetic resonance imaging of polymer gel was recently introduced. This dosimetry system is based on radiation induced chain polymerization of acrylic monomers in a muscle equivalent gel and provide accurate 3 dimensional dose distribution. We planned this study to evaluate the clinical value of this 3-dimensional dosimetry.
MATERIALS AND METHODS: The polymer gel poured into a... |
