Dose-volume analysis of target volume and critical structures in computed tomography image-based multicatheter high-dose-rate interstitial brachytherapy for head and neck cancer
Purpose To evaluate dose-volume relationships of target volume and critical structures in computed tomography (CT) image-based brachytherapy for head and neck cancer. Material and methods Thirty-seven patients with mobile tongue, floor of mouth, and base of tongue cancer treated with brachytherapy (post-operative alone and as a boost after external beam radiotherapy [EBRT], or definitive alon...
متن کاملInterstitial high-dose-rate brachytherapy after breast conserving surgery.
We evaluated local recurrence, toxicity rate and cosmetic outcome in 72 patients treated with high-dose-rate (HDR) brachytherapy after breast conserving surgery. HDR brachytherapy was administered: i) as partial breast irradiation (PBI) in 64 patients with low-risk early stage breast cancer, enrolled in a phase II prospective study; ii) as PBI after a second conservative surgery as treatment of...
متن کاملHigh-dose-rate interstitial brachytherapy for mobile tongue cancer: preliminary results of a dose reduction trial
PURPOSE To compare the outcome of our facility with another about the shortened schedule (60 Gy in 10 fractions to 54 Gy in 9 fractions) of high-dose-rate interstitial brachytherapy (HDR ISBT) for mobile tongue cancer. MATERIAL AND METHODS Eighteen patients were treated with HDR ISBT as a monotherapy in dose reduction schedule with some unique technique to determine the border of tumor accura...
متن کاملDose volume histogram analysis of normal structures associated with accelerated partial breast irradiation delivered by high dose rate brachytherapy and comparison with whole breast external beam radiotherapy fields
PURPOSE To assess the radiation dose delivered to the heart and ipsilateral lung during accelerated partial breast brachytherapy using a MammoSite applicator and compare to those produced by whole breast external beam radiotherapy (WBRT). MATERIALS AND METHODS Dosimetric analysis was conducted on patients receiving MammoSite breast brachytherapy following conservative surgery for invasive duc...
متن کاملDose gradient impact on equivalent dose at 2 Gy for high dose rate interstitial brachytherapy
PURPOSE To evaluate a new calculation model estimating the equivalent dose at 2 Gy (EQD2) taking into account dose gradient in high dose rate interstitial brachytherapy (HDRIB). MATERIAL AND METHODS Forty dose-volume histograms (DVHs) of breast (20 pts) and prostate (20 pts) cancer dose distributions were reviewed. Physical prescribed doses (PPD) were 34 Gy (10f/5d) and 18 Gy (6f/2d) for brea...
