PURPOSE: To analyze the postoperative radiotherapy results and prognostic factors in patients with WHO grade 3 and 4 gliomas.
MATERIALS AND METHODS: A total of 99 patients with malignant gliomas who underwent postoperative radiotherapy between 1988 and 2007 were enrolled in this study. Total resections, subtotal resections (> or =50%), partial resections (<50%), and biopsies were performed in 16, 38, 22,... |

|
|
PURPOSE: To retrospectively assess the advantages and side effects of prophylactic Paraaortic irradiation in cervical cancer patients with common iliac nodal involvement, the results for survival, patterns of failure, and treatment-related toxicity.
MATERIALS AND METHODS: From May 1985 to October 2004, 909 patients with cervical carcinoma received postoperative radiotherapy at the Seoul National University Hospital.
Among them, 54 patients with positive common... |

- Palliative Irradiation Using Helical Tomotherapy in Recurrent Pelvic Tumors with Prior Radiotherapy
- Chul Seung Kay, Eun Jung Yoo, Ji Hoon Kim, Duck Young Ro, Ki Jun Kim
-
Radiat Oncol J. 2010;28(3):133-140.
-
|
|
PURPOSE: We retrospectively investigated the effect of irradiation using helical tomotherapy in recurrent pelvic tumors that underwent prior irradiation.
MATERIALS AND METHODS: Fourteen patients with recurrent pelvic tumors consisting of rectal cancer (57.1%), cervical cancer (35.7%) and cancer with an unknown origin (7.1%) were treated with tomotherapy. At the time of irradiation, median tumor size was 3.5 cm and 7 patients... |

-
|
|
PURPOSE: We examined the radioprotective effects of 5-androstendiol (5-AED), a natural hormone produced in the reticularis of the adrenal cortex, as a result of intestinal damage in gamma-irradiated C3H/HeN mice.
MATERIALS AND METHODS: Thirty mice (C3H/HeN) were divided into three groups; 1) non-irradiated control group, 2) irradiated group, and 3) 5-AED-treated group prior to irradiation. Next, 5-AED (50 mg/kg per body... |

- Combination Effect of Nimotuzumab with Radiation in Colorectal Cancer Cells
- Hye Kyung Shin, Mi Sook Kim, Jae Hoon Jeong
-
Radiat Oncol J. 2010;28(3):147-154.
-
|
|
PURPOSE: To investigate the radiosensitizing effect of the selective epidermal growth factor receptor (EGFR) inhibitor nimotuzumab in human colorectal cancer cell lines.
MATERIALS AND METHODS: Four human colorectal cancer cell lines, HCT-8, LoVo, WiDr, and HCT-116 were treated with nimotuzumab and/or radiation. The effects on cell proliferation, viability, and cell cycle progression were measured by MTT, clonogenic survival assay, flow cytometry,... |

- Evaluation of the Positional Uncertainty of a Liver Tumor using 4-Dimensional Computed Tomography and Gated Orthogonal Kilovolt Setup Images
- Sang Gyu Ju, Chae Seon Hong, Hee Chul Park, Jong Ho Ahn, Eunhyuk Shin, Jung Suk Shin, Jin Sung Kim, Youngyih Han, Do Hoon Lim, Doo Ho Choi
-
Radiat Oncol J. 2010;28(3):155-165.
-
|
|
PURPOSE: In order to evaluate the positional uncertainty of internal organs during radiation therapy for treatment of liver cancer, we measured differences in inter- and intra-fractional variation of the tumor position and tidal amplitude using 4-dimentional computed radiograph (DCT) images and gated orthogonal setup kilovolt (KV) images taken on every treatment using the on board imaging (OBI) and real time... |

- PTV Margins for Prostate Treatments with an Endorectal Balloon
- Hee Jung Kim, Jin Beom Chung, Sung Whan Ha, Jae Sung Kim, Sung Joon Ye
-
Radiat Oncol J. 2010;28(3):166-176.
-
|
|
PURPOSE: To determine the appropriate prostate planning target volume (PTV) margins for 3-dimensitional (3D) conformal radiotherapy (CRT) and intensity-modulated radiation therapy (IMRT) patients treated with an endorectal balloon (ERB) under our institutional treatment condition.
MATERIALS AND METHODS: Patients were treated in the supine position. An ERB was inserted into the rectum with 70 cc air prior to planning a CT scan... |

|
|
PURPOSE: Simulation using computed tomography (CT) is now widely available for radiation treatment planning for breast cancer. It is an important tool to help define the tumor target and normal tissue based on anatomical features of an individual patient. In Korea, most patients have small sized breasts and the purpose of this study was to review the margin of treatment... |

|
PURPOSE: To evaluate the structural characteristics of a scientific network of radiation oncology society.
MATERIALS AND METHODS: A total of 1,512 articles published from 1986 to April 2010 with the terms 'radiation oncology' or 'therapeutic radiology' were obtained in the KoreaMed database. The co-authors were analyzed according to their affiliation, and their relationship was used to build a matrix. With the... |
