Use of ultrasound in image-guided high-dose-rate brachytherapy: enumerations and arguments

Journal of Contemporary Brachytherapy, 2017
Inherently, brachytherapy is the most conformal radiotherapeutic technique. As an aid to brachytherapy, ultrasonography (USG) serves as a portable, inexpensive, and simple to use method allowing for accurate, reproducible, and adaptive treatments.

A Feasibility Study of the Repurposing of Prazosin to Improve Treatment Outcomes in Men Receiving Radiotherapy for Prostate Cancer (MiniRaP‐00)

The Prostate, EarlyView.
ABSTRACT Background Further work is needed to improve treatment outcomes for prostate cancer (PCa), with the repurposing of the α1‐adrenoreceptor antagonists presenting a potential solution. This feasibility clinical trial presents the first prospective data of the use of an α1‐adrenoreceptor antagonist in men undergoing radiotherapy for PCa.

Combined CONVentional with HYPOfractionated regimen (CONV-HYPO) alternative instead of conventionally fractionated radiotherapy to improve treatment outcomes

Nowotwory
For years, the process of accelerated repopulation recognized as a dominant factor for radiotherapy failures has beendeduced rather than proved by direct clinical data. It sounds logical and that towards the end of fractionated radiotherapyresidual tumor

A Brief Review of Low-Dose Rate (LDR) and High-Dose Rate (HDR) Brachytherapy Boost for High-Risk Prostate

Frontiers in Oncology, 2019
For patients with unfavorable or high-risk prostate cancer, dose escalated radiation therapy leads to improved progression free survival but attempts to deliver increased dose by external beam radiation therapy (EBRT) alone can be limited by late ...

Metastatic prostate cancer recurrence within a percutaneous computed tomography guided needle biopsy tract: A rare case report

UroPrecision, EarlyView.
Abstract Background Metastatic prostate cancer tumor seeding within a percutaneous biopsy tract is rare. While reports of tumor seeding following perineal and transrectal prostate biopsies exist, no cases of prostate cancer tumor seeding along a metastatic percutaneous bone biopsy tract detected by prostate specific membrane antigen (PSMA) positron ...

Clinical efficacy of CT-guided 125I brachytherapy in patients with local residual or recurrent hepatocellular carcinoma after thermal ablation

Insights into Imaging, 2022
Key points 125I brachytherapy is a treatment for locally recurrent HCC after ablation. 125I brachytherapy combined with ablation may improve tumor control. Vascular invasion, multiple lesions, and AFP are prognostic risk factors.

Timing for Radiotherapy Initiation After Dental Extraction and Risk of Osteoradionecrosis in Head and Neck Cancer Patients: A Systematic Review and Meta‐Analysis

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Background Head and neck cancer (HNC) patients are advised to undergo dental extraction of teeth with poor prognosis prior to radiotherapy (RT) initiation to prevent osteoradionecrosis (ORN). However, insufficient healing time may result in persistent extraction wounds during RT, which constitute a potential risk factor for ORN, whereas ...
