Monte Carlo dosimetry of a novel Yttrium-90 disc source for episcleral brachytherapy
CONCLUSION: Monte Carlo simulations were successfully performed to confirm the measured PDD curve of the novel Y-90 disc source. This simulation work laid a solid foundation for characterizing the full dosimetry parameters of this source for episcleral brachytherapy applications.PMID:37708092 | DOI:10.1002/acm2.14140

The role of multidisciplinary team and stepwise pelvic devascularization to minimize blood loss during total pelvic exenteration for patients refusing blood transfusion
We describe the case of a female Jehovah's Witness patient in her 60s undergoing pelvic exenteration, focusing on the preoperative, intraoperative, and postoperative measures that allowed an uncomplicated surgery without blood transfusion. Blood transfusions are common in the surgical management of gynecology oncology patients, up to 93% of patients undergoing pelvic exenteration may require blood products. However, increasingly more patients are cautious in receiving blood products, either for fear of potential risks or for religious believes. It is therefore vital to optimize the management of these patients in order to ...

Uncertainty in magnetic resonance imaging-based prostate postimplant dosimetry: Results of a 10-person human observer study, and comparisons with automatic postimplant dosimetry
Uncertainties in postimplant quality assessment (QA) for low-dose-rate prostate brachytherapy (LDRPBT) are introduced at two steps: seed localization and contouring. We quantified how interobserver variability (IoV) introduced in both steps impacts dose-volume-histogram (DVH) parameters for MRI-based LDRPBT, and compared it with automatically derived DVH parameters.

Benchmarking ChatGPT-4 on a radiation oncology in-training exam and Red Journal Gray Zone cases: potentials and challenges for ai-assisted medical education and decision making in radiation oncology
ConclusionBoth evaluations demonstrate the potential of ChatGPT-4 in medical education for the general public and cancer patients, as well as the potential to aid clinical decision-making, while acknowledging its limitations in certain domains. Owing to the risk of hallucinations, it is essential to verify the content generated by models such as ChatGPT for accuracy.

Are 7.5gy ×2 fractions more efficient than 6gy×3 in exclusive postoperative endometrial cancer brachytherapy? a clinical and dosimetrical analysis
CONCLUSION: Considering the lack of vaginal relapses and similar LVT over time, 7.5Gy×2fractions seem more efficient in terms of patient comfort, workload, and cost. This is the first study using dosimetry parameters to compare effectivity of schedules. Larger series are needed to confirm the present results.PMID:37699447 | DOI:10.1016/j.radonc.2023.109909

Clinical outcomes of radioactive seed brachytherapy and microwave ablation in inoperable stage I non-small cell lung cancer
This study assessed the efficacy and safety of radioactive iodine-125 seed ablation brachytherapy (RSABT) in comparison to microwave ablation therapy (MWAT) for treating inoperable stage I non-small cell lung cancer (NSCLC). We conducted a retrospective analysis of data from stage I NSCLC patients who underwent CT-guided RSABT or MWAT. The primary outcomes measured were progression-free survival (PFS), overall survival (OS), and the occurrence of adverse events. Of the patients included in the study, 71 underwent RSABT and 105 received MWAT. The median follow-up time for these groups was 47.4 months and 60 months, respecti...

The American Brachytherapy Society and Indian Brachytherapy Society consensus statement for the establishment of high-dose-rate brachytherapy programs for gynecological malignancies in low- and middle-income countries
The global cervical cancer burden is disproportionately high in low- and middle-income countries (LMICs), and outcomes can be governed by the accessibility of appropriate screening and treatment. High-dose-rate (HDR) brachytherapy plays a central role in cervical cancer treatment, improving local control and overall survival. The American Brachytherapy Society (ABS) and Indian Brachytherapy Society (IBS) collaborated to provide this succinct consensus statement guiding the establishment of brachytherapy programs for gynecological malignancies in resource-limited settings.
