## What is/are Brachytherapy Dose?

Brachytherapy Dose - An LDR brachytherapy dose of 20-60 Gy was administered, corresponding to biologically effective dose values of 15-53 Gy and equivalent dose values of 12-43 Gy.^{[1]}Methods A previously validated in-house brachytherapy dose calculation program was used for ODD calculations.

^{[2]}PURPOSE There is a growing trend towards the adoption of model-based calculation algorithms (MBDCAs) for brachytherapy dose calculations which can properly handle media and source/applicator heterogeneities.

^{[3]}Escalated proton plans did not meet the brachytherapy dose volumes in any plan, and doses along the entry paths rose to over 150% of the prescription.

^{[4]}Brachytherapy doses were based on our current institutional standards: 10.

^{[5]}Optimizing brachytherapy doses for young children and establishing a clear and long term follow-up protocol, could help to reduce these complications.

^{[6]}The mean dose difference at the landmarks after mapping the external radiotherapy and brachytherapy dose distributions was 1.

^{[7]}Then, brachytherapy dose distribution of a new model of the human eye was investigated for a 14-mm COMS eye plaque loaded with these sources with GATE Monte Carlo simulation.

^{[8]}EBRT and three-dimensional brachytherapy dose fusion values were calculated for target areas and OARs using Elastix V5.

^{[9]}Potential Applications: The CLRP EPv2 database provides accurate reference 3D dose distributions to advance ocular brachytherapy dose evaluations.

^{[10]}Use of equivalent dose at 2 Gy per fraction (EQD2) models has allowed incorporation of external beam radiotherapy dose to the brachytherapy dose leading to development of consolidated dose constraints for organs-at-risk in the modern era.

^{[11]}Future improvement of brachytherapy dose delivery methods and techniques may continue to prolong control rates and improve outcomes for this challenging group of patients.

^{[12]}All patients received a brachytherapy dose of 21 Gray (Gy)/3 fractions (#) after concurrent chemo-radiotherapy (50.

^{[13]}The brachytherapy dose is delivered from parallel-opposed beams from 192Ir sources in circle applicators.

^{[14]}Material and Methods: In this prospective study, 20 patients with cervical cancer stages (IIB-IIIB) were planned for a brachytherapy dose of 7Gy per fraction for three fractions using 2D image-based treatment plan and CT-based plan.

^{[15]}Purpose To observe the effect of different high-dose-rate (HDR) intracavitary brachytherapy dose schedules on equieffective dose in 2 Gy per fraction (EQD2).

^{[16]}The brachytherapy dose was 14 Gy in 2 fractions of 7 Gy each.

^{[17]}The biggest factors influencing the brachytherapy dose distributions are the number of available channels and their separation from each other within the target.

^{[18]}Future work will incorporate the brachytherapy dose to the ovarian-sparing CTV and assess the clinical response of this technique as a means to preserve ovarian endocrine function.

^{[19]}CONCLUSIONS We outlined two methods for achieving higher high-dose-rate brachytherapy dose conformity using the tungsten shielding rods (to spare contralateral healthy tissues) and double-balloon technique (to decrease dose gradient within the target to minimize dose to the proximal mucosa).

^{[20]}The median EBRT dose was 50Gy and Brachytherapy dose received was 23Gy.

^{[21]}The brachytherapy dose was 16Gy in four fractions of 4Gy each.

^{[22]}Local control was worse with adenocarcinomas, HRCTV >40 cm3 at brachytherapy, requirement for a higher brachytherapy dose, and treatment >51 days.

^{[23]}Additional investigation to define the optimal single-fraction HDR brachytherapy dose is warranted, and single-fraction treatment currently should not be offered outside the context of a clinical trial.
