Pulsed dose rate brachytherapy of lip cancer
PURPOSE PURPOSE To present our experience with pulsed dose rate brachytherapy (PDR BT) of lip cancer. MATERIAL AND METHODS The study group included 32 T1-4N0M0 lip cancer patients with a median age of 71 years (ranged 41-87 years), treated with interstitial PDR BT to the planned total dose of 60-70 Gy; 1 Gy/pulse, pulses repeated every hour a day. There were 26 untreated patients, and six ...
متن کاملLow-dose-rate or high-dose-rate brachytherapy in treatment of prostate cancer – between options
PURPOSE Permanent low-dose-rate (LDR-BT) and temporary high-dose-rate (HDR-BT) brachytherapy are competitive techniques for clinically localized prostate radiotherapy. Although a randomized trial will likely never to be conducted comparing these two forms of brachytherapy, a comparative analysis proves useful in understanding some of their intrinsic differences, several of which could be exploi...
متن کاملA buccal mucosa carcinoma treated with high dose rate brachytherapy
This manuscript presents a case of early stage squamous cell carcinoma of the left buccal mucosa treated with intensity-modulated radiation therapy (IMRT) followed by a high-dose rate (HDR) brachytherapy boost. With limited literature available on HDR mold (stent) radiotherapy for oral cancer, a discussion on the issues encountered during treatment planning and delivery may prove to be insightf...
متن کاملQuality assurance prusedore in high dose rate bracythrapy
Introduction: Quality assurance is essential for obtaining the best achievable tumor control, avoiding unnecessary side effects, accuracy and safety during performing High Dose Rate (HDR) Brachytherapy (BT). Quality assurance is extremely important because HDR BT procedures are performed quickly, with high doses given in a short time period, with little opportunity for correcti...
متن کاملIs pulsed dose rate more damaging to spinal cord of rats than continuous low dose rate?
BACKGROUND AND PURPOSE Theoretical calculations suggest that pulsed dose-rate irradiation (PDR) should have approximately the same effectiveness as continuous low dose-rate (CLDR) when the same total dose is given in the same overall time, unless large doses per pulse (> 2 Gy) are used and/or non-exponential or very short half-times of repair (< 0.5 h) are present in the irradiated tissues. How...
