Reply to Comment on 'egs_brachy: a versatile and fast Monte Carlo code for brachytherapy'. Phys Med Biol. 2017 Dec 01;: Authors: Thomson RM, Taylor REP, Chamberland MJP, Rogers DWO Abstract We respond to the comments by Dr. Yegin by identifying the source of an error in a fit in our original paper but arguing that the lack of a fit does not affect the conclusion based on the raw data that egs_brachy is an accurate code and we provide further benchmarking data to demonstrate this point.

Whole pelvis radiotherapy (WPRT) may improve clinical outcomes over prostate-only radiotherapy (PORT)in high-risk prostate cancer patients by sterilization of micrometastatic nodal disease provided there is optimal control of the primary site.
Older patients undergoing radiation therapy (RT) for pelvic malignancies are at increased risk for pelvic fracture, which is associated with significant morbidity and mortality. RT techniques such as brachytherapy or intensity modulated RT (IMRT) allow for more conformal dose distributions, but it is not known whether the risk for pelvic fracture varies by RT modality.
African American men have historically had poorer prostate cancer biochemical and survival outcomes than Caucasians. However, emerging data suggest nononcologic factors drive much of this disparity. Prior evidence has suggested an association between a transient prostate specific antigen (PSA) bounce and improved biochemical control. However, racial differences in this relationship have remained relatively unexplored.
We presented the physics preparations and clinical workflow required for implementing MRI-based HDR IBT (MRI-HDR-IBT) of gynecologic cancer patients in a high-volume brachytherapy center. The present document is designed to focus on the clinical steps required from a physicist's standpoint. Those steps include: (a) testing IBT equipment with MRI scanner, (b) preparation of templates and catheters, (c) preparation of MRI line markers, (d) acquisition, importation and registration of MRI images, (e) development of treatment plans and (f) treatment evaluation and documentation. The checklists of imaging acquisition, registrat...

The purpose of the study was to develop and evaluate an automated digitization algorithm for high-dose-rate cervix brachytherapy, with the goal of reducing the duration of treatment planning, staff resources, variability, and potential for human error.
In conclusion, HDR-BT was an effective treatment modality for patients with cervical cancer recurrence in the vaginal stump. PMID: 31579327 [PubMed - in process]
Ultrasound (US) imaging has been proved as an excellent diagnostic tool in gynecology and, due to its wide availability and limited cost, is under intense investigation as base for dose adaptation in cervical ...
