PURPOSE: To evaluate the extent of pain response and objective response to palliative radiotherapy (RT) for bone metastases from hepatocellular carcinoma according to RT dose.
MATERIALS AND METHODS: From January 2007 to June 2010, palliative RT was conducted for 103 patients (223 sites) with bone metastases from hepatocellular carcinoma.
Treatment sites were divided into the high RT dose and low RT dose... |

|
PURPOSE: To evaluate the biochemical control rate and the rate of side effects after performing permanent brachytherapy of localized prostate cancer.
MATERIALS AND METHODS: 67 patients with localized prostate cancer were treated with brachytherapy between April 2007 and December 2008. Of these, 43 patients who were followed up and did not receive external radiotherapy were evaluated for the change in prostate... |

PURPOSE: Flavopiridol enhanced radiation-induced apoptosis of cancer cells in our previous in vitro study. The purpose of this study was to assess if flavopiridol could enhance the radioresponse of mouse mammary tumors in vivo.
MATERIALS AND METHODS: Balb/c mice bearing EMT-6 murine mammary carcinoma were treated with flavopiridol only, radiation only, or both for 7 days. Flavopiridol was administered 2.5 mg/kg... |

PURPOSE: To assess the usefulness of implanted fiducial markers in the setup of hypofractionated radiotherapy for prostate cancer patients by comparing a fiducial marker matched setup with a pelvic bone match.
MATERIALS AND METHODS: Four prostate cancer patients treated with definitive hypofractionated radiotherapy between September 2009 and August 2010 were enrolled in this study.
Three gold fiducial markers were implanted into the... |

-
|
|
PURPOSE: To analyze our quality assurance (QA) data for intensity modulated radiation therapy (IMRT) according to treatment site and to possibly improve QA for IMRT in Hospital.
MATERIALS AND METHODS: We performed QA on 50 patients (head and neck, 28 patients; Breast, 14 patients; Pelvis, 8 patients) for IMRT. The calculated dose from RTP was compared with the measured value film,... |

|
PURPOSE: To assess the degree and clinical impact of location error of the dens on the X-axis during radiotherapy to brain and head and neck tumors.
MATERIALS AND METHODS: Twenty-one patients with brain tumors or head and neck tumors who received three-dimensional conformal radiation therapy or intensity-modulated radiation therapy from January 2009 to June 2010 were included in this study. In... |

- Treatment Planning for Minimizing Carotid Artery Dose in the Radiotherapy of Early Glottic Cancer
- Yong Kan Ki, Won Taek Kim, Ji Ho Nam, Dong Hyun Kim, Ju Hye Lee, Dal Park, Dong Won Kim
-
Radiat Oncol J. 2011;29(2):115-120.
-
|
|
PURPOSE: To examine the feasibility of the treatment planning for minimizing carotid artery dose in the radiotherapy of early glottic cancer.
MATERIALS AND METHODS: From 2007 to 2010, computed tomography simulation images of 31 patients treated by radiotherapy for early glottic cancer were analyzed. The virtual planning was used to compare the parallel-opposing fields (POF) with the modified oblique fields (MOF)... |

The author reports a bile duct cancer patient whose stent shifted significantly from right to left over the course of radiotherapy. The 80-year-old female patient had a short stature with thoracic kyphosis and mutiple spinal compression fractures. She was also emaciated and very lean.
By comparing the weekly scanned computed tomography images, the author found her stent to have shifted by... |
