Objective: To examine the visual and anatomic outcomes of patients with retinal capillary hemangiomas secondary to von Hippel-Lindau (VHL) disease treated with globe-salvaging fractionated external beam radiotherapy (EBRT) after progression of hemangiomas despite initial therapy.
Design: Retrospective noncomparative consecutive case series.
Participants: Review of medical records of 5 patients with retinal capillary hemangiomas secondary to VHL disease.
Intervention: External beam radiotherapy delivered to a total dose of 2160 cGy given over 12 daily fractions.
Main Outcome Measures: Data on visual acuity and tumor size were collected at baseline, 1, 3, 6, and 12 months after EBRT, and at final follow-up, using echography, fundus photographs, and clinical examination.
Results: Six eyes of 5 patients were treated. Mean follow-up was 28.3 months (range, 6-51). Mean baseline visual acuity was 20/70. Mean visual acuity at last follow-up was 20/45 (range, 20/25-20/60). Tumor volume reduction was 27.5 mm(3) (range, 0.9-109.6 mm(3)). Mean percentage reduction in tumor volume was 39.6% (range, 3.3%-71.1%).
Conclusions: External beam radiotherapy is a useful option in the treatment of retinal hemangiomas secondary to VHL disease that progress despite standard therapy. External beam radiotherapy leads to improvement in visual acuity, reduction in tumor volume, and stabilization of retinal detachment in most patients treated.

Outcomes of endometrial cancer prevention strategies in patients with Lynch syndrome: a nationwide cohort study in the Netherlands.
EClinicalMedicine
January 2025
Department of Clinical Genetics, Erasmus MC Cancer Institute, Rotterdam, the Netherlands.
Background: Female Lynch syndrome carriers have an increased risk of developing endometrial cancer. Regardless, research on endometrial carcinoma tumorigenesis is scarce and no uniform, evidence-based gynaecological management guidelines exist. We therefore described gynaecological surveillance and surgery outcomes in a nation-wide Lynch syndrome cohort.

Purpose: Treating stage II endometrial cancer involves total hysterectomy, bilateral salpingo-oophorectomy, and risk-adapted adjuvant therapy. Professional guidelines support various adjuvant treatments, but high-level data supporting specific options are conflicting. We sought to evaluate adjuvant radiation therapy (RT) trends for these patients, hypothesizing increased utilization of pelvic external beam RT (EBRT) over time.

Purpose: To evaluate the efficacy of ultrasound-guided ruthenium (Ru 106) plaque brachytherapy for treatment of exudative retinal detachment in diffuse choroidal haemangioma (DCH).
Methods: Retrospective analysis of four paediatric patients treated with ultrasound-guided Ru 106 plaque brachytherapy for DCH with total exudative retinal detachment directed to the thickest part of the DCH. A dose of 40 Gy to the tumour apex was delivered in all patients.
Long-term outcome and antitumor immune activation response in prostate cancer treated with low-dose-rate brachytherapy.
Medicine (Baltimore)
November 2024
Department of Urology, Tianjin Institute of Urology, The Second Hospital of Tianjin Medical University, Tianjin, China.
To evaluate the long-term clinical outcomes of iodine-125 low dose-rate brachytherapy (LDR-BT)-based treatment approaches for ≤ cT3 prostate cancer (PC) patients in China, as well as the effects on the PC immune microenvironment. Data was retrospectively collected from 237 patients with ≤ cT3 PC who were treated with radical prostatectomy (RP) or LDR-BT alone or in combination with androgen deprivation therapy (ADT), and biochemical progression-free survival (bPFS), prostate cancer-specific survival (PCSS) and overall survival (OS) rates were compared. In 63 cases, PC patients received RP after biopsy, received at least 6 months of ADT before RP, or received LDR-BT and deferred limited transurethral resection of the prostate (TURP).

Background And Objective: In 2019 and 2021, Europa Uomo initiated the Europa Uomo Patient Reported Outcome Study (EUPROMS) and the EUPROMS 2.0 survey, with the goal of collecting data on patients' self-reported perspective on physical and mental well-being outside of a clinical trial setting, to be able to investigate the burden of prostate cancer (PCa) treatment from a patient-to-patient perspective. Acknowledging the importance of collecting quality of life (QoL) follow-up data, a 1-yr follow-up (1yrFU) study was conducted to assess the effect of additional PCa treatment on QoL.
