PURPOSE: Concurrent chemoradiotherapy (CCRT) is the standard treatment for locally advanced unresectable pancreatic cancer. However, the introduction of gemcitabine and the recognition of a benefit in patients with advanced disease stimulated the design of trials that compare chemotherapy alone to concurrent chemoradiation. Therefore, we evaluated role of CCRT for locally advanced unresectable pancreatic cancer.
MATERIALS AND METHODS: We carried out a... |

PURPOSE: To examine the effect of suboptimal chemotherapy in patients undergoing preoperative chemoradiotherapy for the treatment of rectal cancer.
MATERIALS AND METHODS: The medical records of 43 patients who received preoperative concurrent chemoradiotherapy, followed by radical surgery for the treatment of pathologically proven adenocarcinoma of the rectum from April 2003 to April 2006 were retrospectively reviewed. The delivered radiation dose ranged... |

|
PURPOSE: The effect of concurrent chemoradiotherapy was analyzed in elderly patients when used in the treatment of locally advanced esophageal cancer.
MATERIALS AND METHODS: The retrospective analysis included 28 elderly patients aged 65 or older, with histopathologically confirmed squamous cell carcinoma of the esophagus, underwent concurrent chemoradiotherapy from January 2001 to July 2007. The squamous cell carcinoma disease stages included 8... |

PURPOSE: To investigate the feasibility of helical tomotherapy on a wide curved area of the skin, and its accuracy in calculating the absorbed dose in the superficial region.
MATERIALS AND METHODS: Two types of treatment plans were made with the cylinder-shaped 'cheese phantom'. In the first trial, 2 Gy was prescribed to a 1-cm depth from the surface.
For the other trial,... |
