Article Synopsis
- The study retrospectively evaluated the effectiveness of ultra-low dose rate brachytherapy (uLDR-BT) in 39 patients with unfavorable intermediate risk prostate cancer, despite current guidelines recommending against it due to insufficient evidence.
- Results showed a promising median follow-up of about 56 months, with an 87.02% biochemical failure-free survival rate, indicating uLDR-BT could be a viable treatment option.
- No significant differences in outcomes were observed based on additional risk factors or treatment methods, suggesting that uLDR-BT's effectiveness is consistent across different patient profiles in the intermediate risk category.
Background: Early-stage high-risk breast cancer (BC) is standardly treated with breast-conserving therapy (BCT), combined with systemic therapy and radiotherapy (RT) ± tumor bed boost, e.g., with interstitial high-dose-rate brachytherapy (HDR-BT).

Radiation retinopathy (RR) and radiation maculopathy (RM) can occur as a result of uveal melanoma radiation treatment and after irradiation of other head and neck extraocular tumors, even with precise targeting techniques, such as stereotactic or proton beam radiotherapy. This review provides an overview of the current understanding of potential radiation damage to ocular tissues, and how recent developments in ophthalmic multimodal imaging techniques and treatment modalities have improved managing options. Several treatment strategies have been employed so far for the management of RR, including laser photocoagulation, intravitreal injections of anti-vascular endothelial growth factor (VEGF) agents or glucocorticosteroids and surgery.

Material And Methods: Medical records of patients who underwent ruthenium plaque treatment for iris and iridociliary melanoma at the Department of Ophthalmology, Poznań University of Medical Sciences, between 1999 and 2021 were retrospectively reviewed.
Results: We identified 24 patients, including 17 women and 7 men, with a median age of 61.
Background And Purpose: We conducted a multicentre real-world study to assess the outcomes of radical salvage re-irradiation for non-melanoma skin cancer (nMSC) recurrences following definitive or postoperative radiotherapy.
Materials And Methods: Data on patients treated between 2006 and 2022 with re-irradiation for nMSCs were retrospectively collected from five high-volume brachytherapy centers. The primary endpoint was local control (LC).
