- Intracranial Extension of Adenoid Cystic Carcinoma of the Palate
- Yoon Kyeong Oh, Keun Hong Kee

Radiat Oncol J. 1999;17(4):293-298.
-
|
Intracranial involvement by adenoid cystic carcinoma (ACC) is very rare and there is no report of intracranial extension from the palate ACC in Korea. Intracranial involvement can occur in one of three ways : direct extension, perineural spread, and hematogenous spread. A case report of a 35-year-old woman with intracranial ACC is presented. Initially she had ACC of the right... |

- Radiation Therapy of Intracranial Germinomas: Optimum Radiation Dose and Treatment Volume
- Sei Kyung Chang, Chang Ok Suh, Gwi Eon Kim
-
Radiat Oncol J. 1999;17(4):269-274.
-
|
PURPOSE: To evaluate the possibility of decreasing the radiation dose and to determine optimum treatment volume in intracranial germinomas.
MATERIALS AND METHODS: Forty five patients with pathologically-verified or presumed germinomas by a radiosensitivity test who had been treated with radiotherapy (RT) alone between 1971 and 1992 were retrospectively analyzed. The average age was 17.2 years with 68.9% of the patients being... |

- Neoadjuvant Chemotherapy and Radiation Therapy inAdvanced Stage Nasopharyngeal Carcinoma
- Semie Hong, Hong Gyun Wu, Charn II Park
-
Radiat Oncol J. 1999;17(4):275-280.
-
|
PURPOSE: To assess the feasibility and the toxicity of the neoadjuvant chemotherapy on the treatment of patients with locoregionally advanced nasopharyngeal carcinoma.
MATERIALS AND METHODS: We analyzed 77 previouly untreated and histologically confirmed advanced stage nasopharyngeal carcinoma patients treated with neoadjuvant chemotherapy followed by radiation therapy at the Seoul National University Hospital between 1984 and 1996. The stage distribution was therapy... |

- The Role of Radiotherapy in Patients with Brain Metastasis
- Soon Nam Lee, Mi Soon Choo, Kyung Ja Lee, Eunmi Nam
-
Radiat Oncol J. 1999;17(4):281-286.
-
|
PURPOSE: Brain metastases are the most frequent metastatic neurologic complication of systemic cancer. Even if the prognosis of brain metastases is grave, with available treatments, most patients experience effective palliation of neurologic symptoms and meaningful extension of life. We evaluated the clinical features and prognostic factors of the patients who were diagnosed as solid tumors with brain metastasis and received... |

- Effect of Protein Kinase C Inhibitor (PKCI) on Radiation Sensitivity and c-fos Transcription Activity
- Eun Kyung Choi, Hyesook Chang, Yun Hee Rhee, Kun Koo Park
-
Radiat Oncol J. 1999;17(4):299-306.
-
|
PURPOSE: The human genetic disorder ataxia-telangiectasia (AT) is a multisystem disease characterized by extreme radiosensitivity. The recent identification of the gene mutated in AT, ATM, and the demonstration that it encodes a homologous domain of phosphatidylinositol 3-kinase (PI3-K), the catalytic subunit of an enzyme involved in transmitting signals from the cell surface to the nucleus, provide support for a role... |

- Effect of Small Dose of Radiation on Induction of Apoptosis in Murine Tumors
- Jinsil Seong, Hong Ryull Pyo, Eun Ji Chung, Sung Hee Kim, Chang Ok Suh
-
Radiat Oncol J. 1999;17(4):307-313.
-
|
PURPOSE: To investigate the presence of adaptive response by low dose radiation in murine tumors in relation to radiation induced apoptosis as well as related mechanism.
MATERIALS AND METHODS: Syngeneic murine tumors, OCa-I and HCa-I, were given 0.05 Gy pretreatment followed by therapeutic dose of 25 Gy radiation. Induction of apoptosis was analyzed for each treatment group. Regulating molecules of apoptosis,... |

- Effect of the Paclitaxel and Radiation on the Gastric Mucosa of the Rat
- Kyung Ja Lee, Heasoo Koo
-
Radiat Oncol J. 1999;17(4):314-320.
-
|
PURPOSE: Paclitaxel is a chemotherapeutic agent with potent microtubule stabilizing activity that arrests cells in G2-M phase. Because G2 and M are the most radiosensitive phase of the cell cycle, paclitaxel has potential role as a cell-cycle specific radiosensitizer. This study was performed to see the effects of paclitaxel on the radiation-induced damage of gastric mucosa of the rat.

- In vivo and in vitro Confirmation of Dose Homogeneity in Total Body Irradiation with Thermoluminescent Dosimeter
- Eui Kyu Chie, Suk Won Park, Wee Saing Kang, Il Han Kim
-
Radiat Oncol J. 1999;17(4):321-338.
-
|
PURPOSE: Total body irradiation (TBI) or whole body irradiation is used to acquire immune suppression, to treat malignant lymphoma and leukemia, and as an conditioning regimen for bone marrow transplantation. For these purposes, many methods were developed to obtain homogenous dose distribution. The objective of this study was to analyze and confirm the accuracy and the homogeneity of the treatment... |
