A multilevel perspective on MSH6‐associated Lynch syndrome: Integrating molecular, biological, and clinical insights

open access: yesInternational Journal of Cancer, EarlyView.
Abstract Lynch syndrome (LS) is the most common hereditary colorectal cancer syndrome, caused by a germline pathogenic variant in one of the mismatch repair (MMR) genes. Among these, MSH6‐associated LS represents a distinct subtype with unique molecular and clinical characteristics.

Hypervision Proton Surgery: The Future Direction of Proton Therapy

open access: yesiNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

Targeting GRP78 and the Proteostasis Network to Break the Therapeutic Ceiling in Neuroendocrine Prostate Cancer

open access: yesiNew Medicine, EarlyView.
ABSTRACT HSPA5 (also known as GRP78/BiP) is a master regulator of the endoplasmic reticulum (ER) stress response and a key node in the proteostasis network. In neuroendocrine prostate cancer (NEPC), an aggressive, therapy‐refractory lineage that emerges under pressure from androgen receptor (AR) directed therapies, GRP78 is upregulated and co‐opted to ...

An efficient and robust MRI-guided radiotherapy planning approach for targeting abdominal organs and tumours in the mouse.

open access: yesPLoS ONE, 2017
IntroductionPreclinical CT-guided radiotherapy platforms are increasingly used but the CT images are characterized by poor soft tissue contrast. The aim of this study was to develop a robust and accurate method of MRI-guided radiotherapy (MR-IGRT ...

Motion Mitigation Techniques for Abdominal and Cardiac MR Imaging

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT MRI of the heart and abdominal organs provides unparalleled soft tissue contrast and quantitative biomarkers, yet remains highly susceptible to physiological motion. Contractions of the myocardium, respiratory excursions, peristalsis, vascular pulsatility, and unpredictable bulk patient movement generate artifacts that impair image quality ...

Quantitative Real‐Time MRI for the Assessment of Gastric Motility

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Current reference standards for measuring gastric emptying and motility are not considered optimal due to the time required, ionizing radiation, invasiveness, and spatial resolution. Purpose To assess gastric motility using novel real‐time dynamic magnetic resonance imaging in combination with static measurements for gastric ...

Magnetic Resonance Guided Radiation Therapy (MRgRT) Prostate Motion and Margins

open access: yesJournal of Medical Radiation Sciences, EarlyView.
This study evaluated intra‐fractional prostate motion during MR‐guided radiotherapy to determine appropriate PTV margins for prostate cancer. Analysis of 18 patients resulted in calculated margins of 3.2 mm (AP), 1.7 mm (LR), and 3.2 mm (SI), supporting the potential for margin reduction with MRgRT. ABSTRACT Introduction Systematic and random errors in
