PURPOSE: Although using the high energy photon beam with conventional parallel-opposed beams radio-therapy for nasopharyngeal carcinoma, radiation-induced xerostomia is a troublesome problem for patient. We conducted this study to explore a new parotid gland sparing technique in 3-D conformal radiotherap (3-D CRT) in an effort to prevent the radiation-induced xerostomia.
MATERIALS AND METHODS: We performed three different planning for four clinically... |

-
|
PURPOSE: We performed the retrospective analysis to find the outcome of external beam radiotherapy alone in advanced esophageal cancer patients.
METHODS AND MATERIALS: One hundred and six patients treated with external beam radiotherapy alone between July 1990 and December 1996 were analyzed retrospectively. We limited the site of the lesions to the thoracic esophagus and cell type to the squamous cell... |

|
PURPOSE: The incidence of adenocarcinoma of the uterine cervix is low. Traditionally, Low Dose R ate (LDR) brachytherapy has been used as a standard modality in the treatment for patients with carcinoma of the uterine cervix. The PURPOSE of this report is to evaluate the effects of the High dose rate (HL)R) brachytherapy in the patients with adenocarcinoma of the... |

Radiat Oncol J. 2000;18(1):51-58.
-
|
PURPOSE: The effect of PTK inhibitors (herbimycin A and genistein) on the induction of radiation-induce d apoptosis in Ph-positive K562 leukemia cell line was investigated.
MATERIALS AND METHODS: K562 cells in exponential growth phase were irradiated with a linear accelerator at room temperature. For 6 MV X-ray irradiation and drug treatment, cultures were initiated at 2x10' cells/mL. The cells were irradiated... |

|
PURPOSE: To evaluate protective mechanism of melatonin against radiation damage and its relationship with apoptosis in mouse jejunum.
MATERIALS AND METHODS:' 168 mice were divided into 28 groups according to radiation dose and melatonin treatment.
To analysis crypt survival, microcolony survival assay was done according to Withers an (l Elkind's method. To analysis apoptosis, TUNEL assay was done according to Labet-Moleur's method.

BACKGROUND: The authors have developed a Digital image chart(DIC) and digital Radiotherapy Record System (DRRS). We have evaluated the DIC and DRRS for reliability, usefulness, ease of use, and efficiency. METHOD AND MATERIALS: The basic design o f the DIC and DRRS was to build an digital image database of radiation therapy patient records for a more efficient and timely... |
