”Maximum dose” points in cervical and endometrial cancer medium dose rate brachytherapy
Background: Best dose distribution in target volume and control of Organ at Risk (OAR) dose are the two main goals in brachytherapy. Materials and Methods: In this study in vivo dosimetry in 4 rectal points was performed by Transillumination Dosimeter (TLD) s and the measured doses were compared in different patients. One point was reported to have the maximum dose in each patient and the very ...
متن کاملPulsed 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 کاملApplicator Attenuation Effect on Dose Calculations of Esophageal High-Dose Rate Brachytherapy Using EDR2 Film
Introduction Interaluminal brachytherapy is one of the important methods of esophageal cancer treatment. The effect of applicator attenuation is not considered in dose calculation method released by AAPM-TG43. In this study, the effect of High-Dose Rate (HDR) brachytherapy esophageal applicator on dose distribution was surveyed in HDR brachytherapy. Materials and Methods A cylindrical PMMA phan...
متن کاملDo androgen deprivation and the biologically equivalent dose matter in low‐dose‐rate brachytherapy for intermediate‐risk prostate cancer?
The objective of this study was to investigate the impact of the biologically equivalent dose (BED) on treatment outcomes after iodine-125 low-dose-rate brachytherapy (LDR-BT) with or without supplemental external beam radiotherapy (EBRT) and androgen deprivation therapy (ADT) for intermediate-risk prostate cancer (PCa). We retrospectively evaluated 292 Japanese patients. The impact of the BED ...
متن کاملHigh-dose-rate and pulsed-dose-rate brachytherapy for oral cavity cancer and oropharynx cancer
Interstitial brachytherapy represents the treatment of choice for small tumours, regionally localized in the oral cavity and the oropharynx. In the technical setting, continuous low-dose-rate (LDR) brachytherapy represented for many years the gold standard for administering radiation in head and neck brachytherapy. Large series of head and neck cancer patients treated with LDR brachytherapy hav...
