PURPOSE: This study was performed for the evaluation of the feasibility and toxicity of hypofractionated radiation therapy for early glottic cancer METHODS AND MATERIALS: From February 1999 to February 2000, 20 patients with histologically confirmed Stage I, II glottic cancer were enrolled into this study. There were 18 males and 2 females, the median age of the patients was 59... |

Intramedullary spinal cord metastases (ISCM) account for only 3.4% of symptomatic metastases to the spinal cord. The survival of patients with ISCM is characteristically short, often no longer than 2 months, due to a rapid neurologic deterioration and the presence of widespread metastases, including metastases to the brain. We report two cases of ISCM arising from primary sphenoid sinus carcinoma... |

|
PURPOSE: In this retrospective study, we attempted to evaluate the treatment outcome and the prognostic factors of thymoma treated with surgery, radiotherapy and chemotherapy.
METHODS AND MATERIALS: Between 1979 and 1998, 55 patients with thymoma were treated at the Seoul National University Hospital. Of these, 11 patients underwent surgery only, 33 patients received postoperative radiotherapy and 11 patients received radiotherapy... |

|
PURPOSE: To assess the locoregional recurrence rate, survival rate and prognostic factors after modified radical mastectomy and postoperative adjuvant radiation therapy with or with chemotherapy in high-risk breast cancer patients.
METHODS: Between 1984-1995, 48 patients underwent postoperative irradiation to the regional lymphatics and chest wall due to large tumor size (> or = 5 cm) or small tumor size (<5 cm)... |

|
PURPOSE: Planning target volume (PTV) for tumors in abdomen or thorax includes enough margin for breathing-related movement of tumor volumes during treatment. Depending on the location of the tumor, the magnitude of PTV margin extends from 10 mm to 30 mm, which increases substantial volume of the irradiated normal tissue hence, resulting in increase of normal tissue complication probability (NTCP).... |

PURPOSE: To evaluate the treatment results and prognostic factors after radiotherapy in stage IIB uterine cervix cancer.
MATERIALS AND METHODS: We retrospectively analyzed the records of 90 patients with stage IIB uterine cervix cancer who received radiotherapy between 9/94 and 12/99. Age was ranged from 28 to 79 years (median 57). Tumor size was > or = 4 cm in 64... |

|
PURPOSE: By developing on-line statistics program to record the information of radiation oncology to share the information with internet. It is possible to supply basic reference data for administrative plans to improve radiation oncology.
MATERIALS AND METHODS: The information of radiation oncology statistics had been collected by paper forms about 52 hospitals in the past. Now, we can input the data... |

- Inductoin of Radioresistance by Overexpression of Glutathione S-Transferase K1 (hGSTK1) in MCF-7 Cells
- Jae Chul Kim, Sei One Shin
-
Radiat Oncol J. 2001;19(4):381-388.
-
|
PURPOSE: This study was conducted to assess the effects of x-irradiation on the expression of the novel glutathione S-transferase K1 gene.
MATERIALS AND METHODS: Human glutathione S-transferase K1 (hGSTK1) DNA was purified and ligated to a pcDNA3.1/Myc-His(+) vector for the overexpression of hGSTK1 gene. MCF-7 cells were transfected with or without the recombinant hGSTK1 gene, and irradiated with 6 MV x-ray.

Radiat Oncol J. 2001;19(4):389-396.
-
|
PURPOSE: To detect differentially expressed genes in the patients with uterine cervical cancer during the radiation therapy.
MATERIALS AND METHODS: In patients with biopsy proven uterine cervical cancer, we took a tumor tissue just before radiation therapy and at 40 minutes after external irradiation of 1.8 Gy. Total RNAs isolated from non-irradiated and irradiated tumor tissue samples were analyzed using the... |
