Comparison of survival rates between patients treated with conventional radiotherapy and helical tomotherapy for head and neck cancer
PURPOSE Compared to conventional radiotherapy (RT), intensity-modulated radiotherapy (IMRT) significantly reduces the rate of treatment-induced late toxicities in head and neck cancer. However, a clear survival benefit of IMRT over conventional RT has not yet been shown. This study is among the first comparative study to compare the survival rates between conventional RT and helical tomotherapy...
متن کاملDose Distribution Analysis of Rapid Arc and Intensity Modulated Radiotherapy Plan in Head and Neck Cancer
Introduction: Globally, intensity-modulated radiation therapy (IMRT) is considered as highly precise and accurate method of radiotherapy planning. This technique amplifies spatial dose distribution conformity by modulating the intensity of radiation beams in each sub-volume. Additionally, it can reduces the dose to surrounding critical organs and deliver the planned dose to targets with the nom...
متن کاملClinical outcomes among patients with head and neck cancer treated by intensity-modulated radiotherapy with and without adaptive replanning.
BACKGROUND The purpose of this study was to determine the effect of adaptive replanning on clinical outcome among patients treated by intensity-modulated radiotherapy (IMRT) for head and neck cancer. METHODS Three hundred seventeen patients underwent IMRT with daily image-guidance for newly diagnosed squamous cell carcinoma of the head and neck to a median dose of 66 Gy (range, 60-74 Gy). Of ...
متن کاملPatterns of local-regional recurrence after conformal and intensity-modulated radiotherapy for head and neck cancer
AIM To evaluate the patterns of loco-regional recurrences in head and neck cancer patients METHODS: Twenty-six out of 112 patients treated with primary or postoperative 3D CRT or IMRT for their primary and recurrent disease between 2007 and 2013 were included. The CT images of recurrent disease were rigidly registered with the primary CT images for each patient. To assess overlaps and overlap l...
متن کاملSurvey of advanced radiation technologies used at designated cancer care hospitals in Japan.
OBJECTIVE Our survey assessed the use of advanced radiotherapy technologies at the designated cancer care hospitals in Japan, and we identified several issues to be addressed. METHODS We collected the data of 397 designated cancer care hospitals, including information on staffing in the department of radiation oncology (e.g. radiation oncologists, medical physicists and radiation therapists),...
