Biochemical failure-free survival of F-rhPSMA-7 and F-flotufolastat PET-guided salvage radiotherapy for patients with recurrent prostate cancer.

Prostate-specific membrane antigen (PSMA)-targeted positron emission tomography (PET) has improved localization of prostate cancer (PC) lesions in biochemical recurrence (BCR) for salvage radiotherapy (SRT). We conducted a retrospective review of patients undergoing F-rhPSMA-7 or F-flotufolastat (F-rhPSMA-7.3)-PET-guided SRT compared with conventional-SRT (C-SRT) without PET.

Analysis of radiation oncology integration within general practitioners' daily patient care: a cross-sectional survey in Germany.

Purpose: General practitioners (GPs) play a crucial role in providing interdisciplinary care for radiation oncology patients. This study aims to understand the specific needs and challenges faced by general practitioners in Germany when treating oncology patients.

Methods: A comprehensive web-based questionnaire with 24 items was disseminated to GPs in Germany via email using survio.

PET/CT-based target volume definition in involved-site radiotherapy for treatment of early-stage nodal follicular lymphoma.

Purpose: Recent advancements in imaging, particularly 18F-fluorodeoxyglucose positron-emission tomography-computed tomography (FDG-PET/CT), have improved the detection of involved lymph nodes, thus influencing staging accuracy and potentially treatment outcomes. This study is a post hoc analysis of the GAZAI trial data to evaluate the impact of FDG-PET/CT versus computed tomography (CT) alone on radiation target volumes for involved-site radiotherapy (IS-RT) in early-stage follicular lymphoma (FL).

Methods: All patients in the GAZAI trial underwent pretherapeutic FDG-PET/CT examinations, which were subject to central quality control.

Superior Anti-Tumor Response After Microbeam and Minibeam Radiation Therapy in a Lung Cancer Mouse Model.

Objectives: The present study aimed to compare the tumor growth delay between conventional radiotherapy (CRT) and the spatially fractionated modalities of microbeam radiation therapy (MRT) and minibeam radiation therapy (MBRT). In addition, we also determined the influence of beam width and the peak-to-valley dose ratio (PVDR) on tumor regrowth.

Methods: A549, a human non-small-cell lung cancer cell line, was implanted subcutaneously into the hind leg of female CD1 mice.

Influence of radiotherapy on cardiac implantable devices and leads-a single-institution analysis and critical evaluation of current guidelines.

Purpose: Increasing life expectancy and advances in cancer treatment will lead to more patients needing both radiation therapy (RT) and cardiac implantable electronic devices (CIEDs). CIEDs, including pacemakers and defibrillators, are essential for managing cardiac arrhythmias and heart failure. Telemetric monitoring of CIEDs checks battery status, lead function, settings, and diagnostic data, thereby identifying software deviations or damage.
