Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022 Abstract Purpose Treatment planning for head‐and‐neck (H&N) cancer, in particular oropharynx, nasopharynx, and paranasal sinus cases, at our center requires noncoplanar proton beams due to the complexity of the anatomy and target location. Targeting accuracy for all beams is carefully evaluated by using image guidance before delivering proton beam ...

Treatment planning with a 2.5 MV photon beam for radiation therapy
Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022 Abstract Purpose The shallow depth of maximum dose and higher dose fall‐off gradient of a 2.5 MV beam along the central axis that is available for imaging on linear accelerators is investigated for treatment of shallow tumors and sparing the organs at risk (OARs) beyond it.

Extramedullary plasmacytoma: Tumor occurrence and therapeutic concepts—A follow‐up
Cancer Medicine, Volume 11, Issue 24, Page 4743-4755, December 2022., 2022 This paper provides an overview of the extramedullary plasmacytoma cases reported between 1999 and 2021. The global patients’ cohort and the current therapy options are compared to our previous report from 1999. Abstract Background Extramedullary plasmacytoma (EMP) is a solitary tumor consisting of neoplastic plasma cells, with very little to no bone ...

Dental management before radiotherapy of the head and neck region: 4‐year single‐center experience
Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1478-1486, December 2022., 2022 Abstract Objective To review our experience with a standardized dental management approach in patients with planned radiotherapy of the head and neck region based on preradiation and follow‐up data. Material and Methods Records of patients who underwent radiotherapy between June 2016 and November 2020 were reviewed.

Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1467-1477, December 2022., 2022 Abstract Background We recently described the tumor immune microenvironment (TIME) in oral squamous cell carcinomas (OSCC) from Sudan by assessing the core of the lesions. However, the invasive tumor front (ITF) is the most active part of OSCC lesions; thus, TIME should also be characterized at the ITF in this patient cohort.

Efficient proton arc optimization and delivery through energy layer pre-selection and post-filtering [PDF]
Med Phys. 2024; 51: 4982-4995, 2023 Proton arc therapy (PAT) has emerged as a promising approach for improving dose distribution, but also enabling simpler and faster treatment delivery in comparison to conventional proton treatments. However, the delivery speed achievable in proton arc relies on dedicated algorithms, which currently do not generate plans with a clear speed-up and ...

Genes, Chromosomes and Cancer, Volume 62, Issue 2, Page 85-92, February 2023., 2023 Abstract Chromosomal translocations with gene fusions are uniquely rare events in paraganglioma, mostly involving UBTF::MAML3 gene fusion. Precedent literature suggests that tumors involving MAML3 gene fusion correlate with poor clinical outcomes. Herein, we report a case of metastatic sporadic paraganglioma harboring EWSR1::CREM gene fusion in a 36 ...
