Case Reports
Malignant Fibrous Histiocytoma of the Maxilla: Report of A case
Yoon Kyeong Oh, Hwan Ho Yeo
Radiat Oncol J. 1995;13(3):225-232.
Malignant fibrous histiocytoma(MFH) of the maxilla is a rare malignant bone tumor. Seven percents of all MFH occur in the head and neck. Approximately 12% of these tumors occur in the maxilla. Local recurrence or distant metastasis was reported in 55% of cases of maxillary MFH. The mean survival time of 30 months was reported from a review of 14...
Second Malignanat Solid Neoplasms in Children Treated with Radiotherapy: Report of Two Cases and Review of Literature
Eun Ji Chung, Chang Ok Suh, Gwi Eon Kim, Chuhl Joo Lyu, Byung Soo Kim
Radiat Oncol J. 1995;13(3):267-276.
Radiotehrapy and chemotherapy can effectively control cancer but can also cause new second cancers to develop as long-term complications especially in childhood cancer. We experienced two patients with second malignant solid neoplasm who had been treated with radiation and chemotherapy for childhood cancers. One female patients with rhabdomyosarcoma of the right popliteal fossa was treated with radiotherapy at total dose...
Original Articles
The Effect of Ginkgo Biloba Extract on Hypoxic Fraction of C3H Mouse Fibrosarcoma
Chul Koo Cho, Chun Ja Yi, Sung Whan Ha, Charn Il Park
Radiat Oncol J. 1995;13(3):205-214.
PURPOSE: To investigate the effect of Ginkgo biloba extract (GBE) on hypoxic cell fraction and metabolic status in fibrosarcoma (FSa II) of C3H mouse. MATERIALS AND METHODS: Fibrosarcoma (Fsa II), 6mm in diameter, growing in the right hindleg muscle of C3H mouse was used for estimation of hypoxic cell fraction using comparison of TCD50. Radiation was given one hour after administrationof...
Results of Radiotherapy in Nasopharyngeal Cancer
Byung Chul Shin, Sun Young Ma, Chang Woo Moon, Ha Yong Yum, Tae Sig Jeung, Myung Jin Yoo
Radiat Oncol J. 1995;13(3):215-224.
PURPOSE: The aim of this study was to assess the effectiveness, survival rate and complication of radiation therapy in nasopharyngeal cancer. MATERIALS AND METHODS: From January 1980 to May 1989, Fifty Patients who had nasopharyngeal carcinoma treated with curative radiation therapy at Kosin Medical Center were retrospectively studied. Thirty seven patients(74%) were treated with radiation therapy alone(Group I) and 13 patients...
Treatment Results and prognostic Factors in Patients with Esophageal Cancer
Weon Kuu Chung, Soo Kon Kim, Min Chul Kim, Myoung Jang, Sun Rock Moon
Radiat Oncol J. 1995;13(3):233-242.
PURPOSE: To analyse clinical outcome and prognostic factors according to treatment modality, this paper report our experience of retrospective study of patients with esophageal cancer. MATERIALS AND METHODS: One hundred and ten patients with primary esophageal cancer who were treated in Presbyterian Medical Center from May 1985 to December 1992. We analysed these patients retrospectively with median follow up time of...
Intraluminal High-Dose-Rate Brachytherapy for the Tumors of Gastrointestinal Tract
Byung Ock Choi, Ihl Bhong Choi, Su Mi Chung, In Ah Kim, Myoung Gyu Choi, Suk Kyun Chang, Kyeong Sub Shinn
Radiat Oncol J. 1995;13(3):243-252.
PURPOSE: Intraluminal High dose rate brachytherapy is an accepted treatment for the tumors of GI tract. However, there is only some limited clinical data for intraluminal high dose rate brachytherapy for the tumors of GI tract. MATERIALS AND METHODS: Between February 1991 and July 1993, 18 patients who have the tumors of GI tract (esophageal cancer-8 cases, rectal cancer-10 cases) were...
Locally Advanced Rectal Carcinoma: Curative Surgery Alone vs. postoperative Radiotherapy and Chemotherapy
Seung Do Ahn, Eun Kyung Choi, Jin Cheon Kim, Sang Hee Kim
Radiat Oncol J. 1995;13(3):253-258.
PURPOSE: To evauate the effects of postoperative radiotherapy an dchemotherapy on the pattern of failure and survival for locally advanced rectal carcinoma, we analyzed the two groups of patients who received curative resection only and who received postoperative radiochemotherapy retrospectively. MATERIALS AND METHODS: From June 1989 to December 1992, ninety nine patients with rectal cancer were treated by curative resection and...
Results of Radiation Therapy in Stage III Uterine Cevical Cancer
Chang Woo Moon, Byung Chul Shin, Ha Yong Yum, Tae Sig Jeung, Myung Jin Yoo
Radiat Oncol J. 1995;13(3):259-266.
PURPOSE: The aim of this study is to analyze the survival rate, treatment failure and complication of radiation therapy alone in stage III uterine cervical cancer. MATERIALS AND METHODS: From January 1980 through December 1985, 227 patients with stage II uterine cervical cancer treated with radiation therapy at Kosin Medical Center were retrospectively studied. Among 227 patients, 72 patients(31.7%) were stage...
Dose Alterations at the Distal Surface by Tissue Inhomogeneity in High Energy Phonton Beam
Young Ai Kim, Tae Jin Choi, Ok Bae Kim
Radiat Oncol J. 1995;13(3):277-284.
PURPOSE: This study was performed to measure dose alteration at the air-tissue interface resulting from rebuild-up due to the loss of charged particle equilibrium in the tissues around the air-tissue interfaces. MATERIALS AND METHODS: The 6 and 10-MV photon beam in dual energy linear accelerator were used to measure the surface dose at the air-tissue interaface. The polystyrene phantom sized 25...
A Study on the Simulation and the measurement of 6 MeV Electron Beam
Sung Ah Lee, Jeong Ok Lee, Sun Rock Moon, Jong Jin Won, Jeong Ku Kang, Seung Kon Kim
Radiat Oncol J. 1995;13(3):285-290.
PURPOSE: We compared the calculated percent depth dose curves of 6 MeV electron beam to that of measured to evaluate the usefulness of Monte-Carlo simulation method in radiation physics. MATERIALS AND METHODS: The radiation dose values of 6 MeV electron beam using EGS4 code with one million histories in water were compared values that were measured form the depth dose curve...
Clinical Application of Wedge Factor
Dong Rak Choi, Yong Chan Ahn, Seung Jae Huh
Radiat Oncol J. 1995;13(3):291-296.
PURPOSE: In general. The wedge factors which are used clinical practives are ignored of dependency on field sizes and depths. In this present, we investigated systematically the depth and field size dependency to determine the absorbed dose more accurately. METHODS: The wedge factors for each wedge filter were measured at various depth (depth of Dmax, 5cm, 10cm, and 15cm) and field...
